1 Introduction

Cancer is a complex disease that is very heterogenic andvariable at cellular level and also differs from one patient tothe other in its behaviour development and outcome [1]Physical metabolic and behavioural variations of cancercells from normal ones arise through the accumulation ofgenetic modifications and help them to proliferate rapidlyescape from host immune surveillance and ultimately in-vade distant tissues [2] Histopathological genetic andepigenetic and clinical outcome variations between andwithin different types of cancers have been the greatest

challenge to understand the disease and develop noveltherapies [3]

Surgery and radiation therapy were the most preferredmeans of treatment to control cancer before 1950 and after1960 respectively [4] Chemotherapy can be done beforesurgery to shrink the tumor or after surgery to kill theremaining cancer cells [5] However most of the chemo-therapeutic drugs lack specificity and tend to rapidly damagenormal dividing tissues causing side effects such as im-munosuppression neurotoxicity and hair loss [6] More-over resistance has also reduced therapeutic efficacy of someanticancer chemotherapeutic drugs [7]

In order to address these limitations tapping nature as amajor source of chemically diverse novel anticancer com-pounds is a consistently proven track [8] Screening naturalproducts yield more hit with more ldquodrug-likerdquo character-istics (absorption andmetabolism) as compared to screeningof rationally designed compounds [9] Furthermorescreening medicinal plants based on traditional use providesa higher chance of finding active plants relative to therandom approach [10]

Ethiopia has a rich and diverse heritage of traditionalmedical practices known for using plants to prepare morethan 90 of the remedies [11] In addition the country hasmore than 6500 higher plant species of which around 12are endemic [12] Reports indicate that up to 80 of thepopulation relies on traditional remedies as a primary sourceof health care [13] Only few ethnobotanical reports fromdifferent agroecological zones of Ethiopia are available in theliterature regarding medicinal plants used for cancertreatment )ese include Bersama abyssinica Buddlejapolystachya Clerodendrum myricoides Dovyalis abyssinicaEkebergia capensis Myrsine melanophloeos Olea capensisPentas lanceolata Sideroxylon oxyacanthum and Zingiberofficinale [14] Bidens macroptera Clematis simensis Ferulacommunis and Punica granatum [15] Rumex abyssinicus[16] Zanthoxylum chalybeum [17] Phytolacca dodecandraand Vinca rosea [18] Kalanchoe lanceolata Stephaniaabyssinica and Vernonia hymenolepis [19] Plumbago zey-lanica [20ndash22] Acalypha acrogyna Carissa spinarumMaytenus ovatus and Salvia nilotica [23] Croton macro-stachyus [24] and Dorstenia barnimiana [25 26]

In view of this fact and considering the weak traditionalrecording and knowledge transfer system and an alarmingrate of environmental degradation finding anticancer plantsand documenting their ethnobotanical information con-stitute an urgent and indispensable task)erefore the mainaim of this study was to establish an inventory of medicinalplants traditionally used to treat cancer in eleven districts ofEthiopia

2 Materials and Methods

21Descriptionof the StudyAreas )is ethnobotanical studywas conducted in four national regional states of EthiopiaOromia Amhara Afar and Southern Nations Nationalitiesand People)e survey included different districts from eachregion namely Bale Robe and Goba from Oromia BahirDar Zuria and Filiklik fromAmhara Gewane fromAfar andWondo Genet Sodo Zuria Doyo Gena North Bench MizanAman and Shako from Southern Nations Nationalities andPeople Regional State (Figure 1) )ese geographicallyculturally and agroecologically different study areas (Ta-ble 1) were selected mainly based on the availability oftraditional healers and recommendations from healthworkers

22 Data Collection A team comprising a botanist andresearchers from Addis Ababa University was set up andhealth authorities were contacted for permission and

identification of traditional herbalists living in each studyarea Altogether 117 traditional healers were approachedusing the snowball technique and 74 traditional healers whoused herbs to manage cancer-like symptoms were selectedEthnobotanical data were collected between January andAugust 2016 mainly through individual interviews with theselected traditional herbalists using a semistructured in-terview questionnaire )e questionnaire was prepared inAmharic language and translated to different local languagesfor traditional healers who do not speak Amharic )isquestionnaire was designed to obtain information in thefollowing areas (i) general data on the informant (ii) schoolattendance (iii) use of plants for cancer treatment (iv)source of the plant material (v) part of the plant used (vi)method of medicinal preparation (vii) route of adminis-tration and (viii) side effects

A traditional healer for the purpose of this study is ldquoaperson who is recognized by the community in which shelives as competent to provide healthcare by using plants andplant productsrdquo Each traditional healer was approachedbriefed about the purpose of the research and asked for hisher verbal consent in talking about cancer and its treatment)ey were assured of the confidentiality of the informationthey provided If plants were mentioned for their anticancerpurposes a botanical sample was collected )ese specimenswere pressed and preserved for later identification at theNational Herbarium Addis Ababa University Addis Ababaand a voucher specimen of each plant was deposited in theinstitute All botanical names have been transcribedaccording to the nomenclature system used by the Plant List(httpwwwtheplantlistorg)

23 Data Analysis )e relative importance of medicinalplants used in the management of cancer-like symptoms instudy areas was assessed using the relative frequency ofcitation (RFC) use value (UV) informants consensus factor(ICF) and cultural importance index (CI)

231 Relative Frequency of Citation (RFC) )e RFC wascalculated by dividing the number of informants that cite aparticular plant species (FC) by the total number of infor-mants in the survey (N) [29]

RFC FCN

232 Use Value (UV) )e use value demonstrates therelative importance of plant species to treat particular ail-ment and it is determined by the following formula [30]

233 Informant Consensus Factor (ICF) Informant con-sensus factor (ICF) was calculated to determine the ho-mogeneity of the information collected about particularplant species to treat specific ailment It was estimated usingthe following formula [31]

ICF Nur minus NtNur minus 1

(3)

where Nur is the number of use reports of informants forparticular ailment category and Nt refers to the number ofspecies used for the ailment category by all informants

234 Cultural Importance Index (CI) Cultural importanceindex (CI) is calculated by the sum of the use reports (UR) ofinformants mentioning each species use (from i1 to iN) ineach use category and adding all the UR of each category(from u1 to uNC) divided by the total number of informantsN )is index is determined by the following formula [29]

3 Results

)e informants consisted of 66 male and 8 female traditionalhealers and they were divided into three age groups 20ndash4041ndash60 andge 61 years Out of 74 interviewed traditionalhealers most of them (N) were adults aged between 41 and60 years Majority of the respondents (702) gained theirknowledge from family members and 82 of all interviewedrespondents practiced ethnomedicine for more than 25years More than 70 of the respondents were either only attheir primary level of education or did not have a formaleducation at all (Figure 2) Traditional healers usually usedtheir intuition and relied on the chronicity and growth ofexternal mass as a means to diagnose cancer Lumpy growthwas the most commonly cited criteria used to diagnosecancer followed by ulcerative wounds and bleeding (Ta-ble 2) However there were instances where some of thehealers claimed to have treated patients already diagnosedwith cancer at modern health institutions Traditional

A total of 53 plant species belonging to 30 families werereported for their anticancer use (Table 3) )e result of thisstudy showed that shrubs (491) herbs (339) trees(132) and climbers (38) were the main sources of po-tential anticancer medicinal plants )is study also indicatedthat leaves (567) were the most commonly used plant partsfollowed by roots (217) bark (67) stem (17) seeds(17) whole plant (17) leaves and roots (5) leaves orstem (17) and leaves or seeds (17) (Figure 3) Most of thereported plants occurred naturally in wild (962) howevercultivationwas also a source (38) Reportedmedicinal plantshave been traditionally claimed to be used to treat differenttypes of ailments including cancer However only few havebeen scientifically investigated for their antiproliferative orcytotoxic activity (Table 4) While comparing the amount anddistribution of anticancer plants in the past ten years

regardless of the study areas all respondents believed that theamount and distribution of these plants are reduced

In the current study the highest UVs were recorded forAloe spp (6) Albizia schimperiana (4) Sida schimperiana(4) Achyranthes aspera (4) Brucea antidysenterica (4)Cleome brachycarpa (3) Leonotis ocymifolia (3) and Prunusafricana (3) )e lowest UVs were obtained for Acokantheraschimperi Acmella caulirhiza Cineraria abyssinica andGnidia involucrata (Table 3) A total of 228 use reports havebeen documented and categorized into seven categories(Table 5) Among these other ailments (463) and skincancer (265) had the highest use reports FurthermoreICF values were also calculated and ranged from 0 to 042)e highest ICF values were recorded in other ailments(042) and breast cancer (032) followed by skin cancer(023) category (Table 5) )e other ailments categorycomprises of diseases such as stomach ache malaria wartswelling wounds evil eye toothache bleeding gastroin-testinal disorder headache bone fracture cough snakebite herpes simplex tonsillitis hypertension dandrufffever and hemorrhoid)e ICF value of the remaining fourcategories (lung cancer colon cancer cervical cancer andthroat cancer) was zero Quantitative ethnobotanical in-dexes such as RFC and CI were calculated in this study to

analyze the ethnobotanical information According to RFCvalues Croton macrostachyus (01) Vernonia auriculifera(004) Clematis simensis (004) and Acmella caulirhiza(004) are the most frequently cited among all reportedplants Croton macrostachyus (016) Dorstenia barnimiana(012) and Aloe spp (008) rank 1st 2nd and 3rd in positionrespectively according to the CI reference Our result alsoshows that the Pearson correlation coefficient of RFC waspositively and negatively correlated to CI and UV re-spectively (Table 6)

Most of the reported remedies prepared from theseplants were either applied topically (50) or taken orally(417) )e remaining remedies were prepared to be ad-ministered either topically or orally (33) both topicallyand orally (17) and intranasally (17) Usually freshplants were finely chopped dried and pounded to powderform )en the powder of either one or the combination ofmore than one plant was either mixed with drinking water orpasted and applied topically In other cases fresh plant partswere decocted and taken orally or crushed and appliedtopically Water was the main medium in preparation ofmost remedies and additives like honey milk and butterwere also used To determine the amount of plant parts usedto prepare remedies traditional healers used spoon fin-gertip and number (in case of fresh leaves) Adverse effectsreported by respondents include vomiting diarrhea andskin ulcers

4 Discussion

Despite the rich biodiversity of the study areas broad ac-ceptability and centuries-old tradition of using traditionalmedicines the number of anticancer plants reported in thisstudy is far less than expected As it was reported by differentethnobotanical studies conducted in different parts ofEthiopia this could be attributed to the attitude of manytraditional healers to guard their indigenous medicalknowledge as a family secret and hence hesitant to share withthe researchers [13 32 73] Justifying the lower number offemale traditional healers (8 11) participated in this studythese studies also inferred that traditional healers usuallypass their knowledge to the first son of the family

In this study in agreement with the studies conducted inFiche district [35] Ghimbi district [20] and Hawassa city[17] of Ethiopia the predominant botanical familiesrecorded listing over 5 plant species each were AsteraceaeFabaceae and Lamiaceae )is could be due to the fact thatthese families are the largest in the flora of Ethiopia andEritrea [15 21 143] Moreover cytotoxicity studies con-ducted on different Mexican plants reported that the highestnumber of plant species with both in vitro and in vivoantineoplasic activities was from these families [20]

)e highest UVs recorded in this study include Aloe spp(6) Achyranthes aspera L (4) Albizia schimperiana (4) Sidaschimperiana (4) and Brucea antidysenterica (4) )e

)e present study also revealed that RFC and CI values ofsome reported species are similar However there is adistinct difference in species ranking using each index Cmacrostachyus is placed in the first position according toboth RFC and CI index)is could be due to the fact that thisspecies is mentioned by many informants and is the mostrecognized plant in most study areas Furthermore CI valueof C macrostachyus is also high suggesting the diversifieduse of the plant V auriculifera and C simensis ranked nextto C macrostachyus according to RFC index On the otherhand D barnimiana and Aloe spp ranked 2nd and 3rd by CIindex It has been suggested that UV value is a good measureof use diversity than the number of citations [144] Inagreement with this UV value in our study is driven byspecies with greatest number of use rather than those citedby more informants )e Pearson correlation coefficient ofminus036 between RFC and UV shows significant negativeassociation between the local importance of each medicinalplant and relative importance of use of plants )is result isin contrast to previous studies that reported a significantpositive correlation between RFC and UV [145 146] On theother hand there is a significant positive correlation betweenRFC and CI (r2 074 plt 0001) implying that their patternmatches across species )e species with larger RFC valueusually have higher CI such as Croton macrostachyus andVernonia auriculifera

Leaves and roots are the most commonly used plantparts in the preparation of remedies in the study districts

Similarly other ethnobotanical studies conducted in dif-ferent parts of Ethiopia also reported that leaves are thedominant plant part followed by root [16ndash18 20] )epreference towards leaves may be because leaves are themain photosynthetic organs in plants and the primaryreservoirs for secondary metabolites with medicinal values[36] In contrary to other ethnobotanical studies [17 18]where the common use of concoctions and oral route werereported in the current study majority of the reportedremedies are prepared from a single plant species and ap-plied topically

Comparative analysis of this study with other ethno-botanical surveys of plants used traditionally in treating andmanaging cancer in Ethiopia [18] Kenya [147] Cameroon[37] Nigeria [19 38] South Africa [39] and Bangladesh[148] revealed some similarities in the plants cited in thesesurveys Of the 30 plant species cited to be used in Ethiopia[18] 7 species are identified in our study Bersama abyssinicaFresen Brucea antidysenterica JF Mill Calpurnia aurea(Ait) Benth Dodonaea angustifolia Lf Dorstenia bar-nimiana Schweinf Kalanchoe petitiana A Rich and Prunusafricana (Hook f ) Kalkm

Although herbal remedies are believed by the generalpublic to be safe [46] some research findings suggestedotherwise For instance traditionally used )ai anticancerplants Ganoderma lucidum (Fr) Karst Houttuynia cordata)unb and Saussurea involucrata Matsum amp Koidz werereported to cause side effects such as headache insomniaconstipation and diarrhea [62] Similarly side effects such asvomiting diarrhea and skin necrosis associated with the useof traditional herbal remedies were reported in this andother ethnobotanical studies conducted in Ethiopia[149 150] Few side effects reported in this study ascompared to other ethnobotanical studies conducted inEthiopia could be attributed to the frequent use of thetopical route of administration Nevertheless consideringthe probability of underreporting adverse effects extensivetoxicological investigations should be conducted to protectthe public

In vitro cytotoxicity and antioxidant properties of someof the plants reported in our study have also been studiedAmong these plants potent cytotoxic activity was reportedfor knipholone anthrone isolated from Kniphofia foliosawith IC50 value that ranges between 09plusmn 01 and33plusmn 04 μgmL [89] Similarly Nibret and Wink reportedthe cytotoxic activity of the crude extract of Acokanthera

5 Conclusion

)e present study showed that traditional healers in elevendistricts of Ethiopia use different medicinal plants to managecancer-like symptoms Frequency of citation value rankedCroton macrostachyus Del Clematis simensis FresenDorstenia barnimiana Schweinf Vernonia auriculiferaHiern and Acmella caulirhiza Del as most cited plantspecies in study areas Hence based on these findings we arecurrently evaluating the in vitro antiproliferative activities ofreported medicinal plant species with a higher frequency ofcitation against human breast adenocarcinoma (MCF-7)human uterine cervical adenocarcinoma (SiSo) human lungcarcinoma (A-427) and human bladder cancer (RT-4) celllines using crystal violate assay However considering therapid disappearance of the traditional knowledge of me-dicinal plants and an urgent need for new anticancer agentsadditional studies have to be conducted to document andscientifically validate traditionally used Ethiopian anticancerplants

In order to address these limitations tapping nature as amajor source of chemically diverse novel anticancer com-pounds is a consistently proven track [8] Screening naturalproducts yield more hit with more ldquodrug-likerdquo character-istics (absorption andmetabolism) as compared to screeningof rationally designed compounds [9] Furthermorescreening medicinal plants based on traditional use providesa higher chance of finding active plants relative to therandom approach [10]

Ethiopia has a rich and diverse heritage of traditionalmedical practices known for using plants to prepare morethan 90 of the remedies [11] In addition the country hasmore than 6500 higher plant species of which around 12are endemic [12] Reports indicate that up to 80 of thepopulation relies on traditional remedies as a primary sourceof health care [13] Only few ethnobotanical reports fromdifferent agroecological zones of Ethiopia are available in theliterature regarding medicinal plants used for cancertreatment )ese include Bersama abyssinica Buddlejapolystachya Clerodendrum myricoides Dovyalis abyssinicaEkebergia capensis Myrsine melanophloeos Olea capensisPentas lanceolata Sideroxylon oxyacanthum and Zingiberofficinale [14] Bidens macroptera Clematis simensis Ferulacommunis and Punica granatum [15] Rumex abyssinicus[16] Zanthoxylum chalybeum [17] Phytolacca dodecandraand Vinca rosea [18] Kalanchoe lanceolata Stephaniaabyssinica and Vernonia hymenolepis [19] Plumbago zey-lanica [20ndash22] Acalypha acrogyna Carissa spinarumMaytenus ovatus and Salvia nilotica [23] Croton macro-stachyus [24] and Dorstenia barnimiana [25 26]

In view of this fact and considering the weak traditionalrecording and knowledge transfer system and an alarmingrate of environmental degradation finding anticancer plantsand documenting their ethnobotanical information con-stitute an urgent and indispensable task)erefore the mainaim of this study was to establish an inventory of medicinalplants traditionally used to treat cancer in eleven districts ofEthiopia

2 Materials and Methods

21Descriptionof the StudyAreas )is ethnobotanical studywas conducted in four national regional states of EthiopiaOromia Amhara Afar and Southern Nations Nationalitiesand People)e survey included different districts from eachregion namely Bale Robe and Goba from Oromia BahirDar Zuria and Filiklik fromAmhara Gewane fromAfar andWondo Genet Sodo Zuria Doyo Gena North Bench MizanAman and Shako from Southern Nations Nationalities andPeople Regional State (Figure 1) )ese geographicallyculturally and agroecologically different study areas (Ta-ble 1) were selected mainly based on the availability oftraditional healers and recommendations from healthworkers

22 Data Collection A team comprising a botanist andresearchers from Addis Ababa University was set up andhealth authorities were contacted for permission and

identification of traditional herbalists living in each studyarea Altogether 117 traditional healers were approachedusing the snowball technique and 74 traditional healers whoused herbs to manage cancer-like symptoms were selectedEthnobotanical data were collected between January andAugust 2016 mainly through individual interviews with theselected traditional herbalists using a semistructured in-terview questionnaire )e questionnaire was prepared inAmharic language and translated to different local languagesfor traditional healers who do not speak Amharic )isquestionnaire was designed to obtain information in thefollowing areas (i) general data on the informant (ii) schoolattendance (iii) use of plants for cancer treatment (iv)source of the plant material (v) part of the plant used (vi)method of medicinal preparation (vii) route of adminis-tration and (viii) side effects

A traditional healer for the purpose of this study is ldquoaperson who is recognized by the community in which shelives as competent to provide healthcare by using plants andplant productsrdquo Each traditional healer was approachedbriefed about the purpose of the research and asked for hisher verbal consent in talking about cancer and its treatment)ey were assured of the confidentiality of the informationthey provided If plants were mentioned for their anticancerpurposes a botanical sample was collected )ese specimenswere pressed and preserved for later identification at theNational Herbarium Addis Ababa University Addis Ababaand a voucher specimen of each plant was deposited in theinstitute All botanical names have been transcribedaccording to the nomenclature system used by the Plant List(httpwwwtheplantlistorg)

23 Data Analysis )e relative importance of medicinalplants used in the management of cancer-like symptoms instudy areas was assessed using the relative frequency ofcitation (RFC) use value (UV) informants consensus factor(ICF) and cultural importance index (CI)

231 Relative Frequency of Citation (RFC) )e RFC wascalculated by dividing the number of informants that cite aparticular plant species (FC) by the total number of infor-mants in the survey (N) [29]

RFC FCN

232 Use Value (UV) )e use value demonstrates therelative importance of plant species to treat particular ail-ment and it is determined by the following formula [30]

233 Informant Consensus Factor (ICF) Informant con-sensus factor (ICF) was calculated to determine the ho-mogeneity of the information collected about particularplant species to treat specific ailment It was estimated usingthe following formula [31]

ICF Nur minus NtNur minus 1

(3)

where Nur is the number of use reports of informants forparticular ailment category and Nt refers to the number ofspecies used for the ailment category by all informants

234 Cultural Importance Index (CI) Cultural importanceindex (CI) is calculated by the sum of the use reports (UR) ofinformants mentioning each species use (from i1 to iN) ineach use category and adding all the UR of each category(from u1 to uNC) divided by the total number of informantsN )is index is determined by the following formula [29]

3 Results

)e informants consisted of 66 male and 8 female traditionalhealers and they were divided into three age groups 20ndash4041ndash60 andge 61 years Out of 74 interviewed traditionalhealers most of them (N) were adults aged between 41 and60 years Majority of the respondents (702) gained theirknowledge from family members and 82 of all interviewedrespondents practiced ethnomedicine for more than 25years More than 70 of the respondents were either only attheir primary level of education or did not have a formaleducation at all (Figure 2) Traditional healers usually usedtheir intuition and relied on the chronicity and growth ofexternal mass as a means to diagnose cancer Lumpy growthwas the most commonly cited criteria used to diagnosecancer followed by ulcerative wounds and bleeding (Ta-ble 2) However there were instances where some of thehealers claimed to have treated patients already diagnosedwith cancer at modern health institutions Traditional

A total of 53 plant species belonging to 30 families werereported for their anticancer use (Table 3) )e result of thisstudy showed that shrubs (491) herbs (339) trees(132) and climbers (38) were the main sources of po-tential anticancer medicinal plants )is study also indicatedthat leaves (567) were the most commonly used plant partsfollowed by roots (217) bark (67) stem (17) seeds(17) whole plant (17) leaves and roots (5) leaves orstem (17) and leaves or seeds (17) (Figure 3) Most of thereported plants occurred naturally in wild (962) howevercultivationwas also a source (38) Reportedmedicinal plantshave been traditionally claimed to be used to treat differenttypes of ailments including cancer However only few havebeen scientifically investigated for their antiproliferative orcytotoxic activity (Table 4) While comparing the amount anddistribution of anticancer plants in the past ten years

regardless of the study areas all respondents believed that theamount and distribution of these plants are reduced

In the current study the highest UVs were recorded forAloe spp (6) Albizia schimperiana (4) Sida schimperiana(4) Achyranthes aspera (4) Brucea antidysenterica (4)Cleome brachycarpa (3) Leonotis ocymifolia (3) and Prunusafricana (3) )e lowest UVs were obtained for Acokantheraschimperi Acmella caulirhiza Cineraria abyssinica andGnidia involucrata (Table 3) A total of 228 use reports havebeen documented and categorized into seven categories(Table 5) Among these other ailments (463) and skincancer (265) had the highest use reports FurthermoreICF values were also calculated and ranged from 0 to 042)e highest ICF values were recorded in other ailments(042) and breast cancer (032) followed by skin cancer(023) category (Table 5) )e other ailments categorycomprises of diseases such as stomach ache malaria wartswelling wounds evil eye toothache bleeding gastroin-testinal disorder headache bone fracture cough snakebite herpes simplex tonsillitis hypertension dandrufffever and hemorrhoid)e ICF value of the remaining fourcategories (lung cancer colon cancer cervical cancer andthroat cancer) was zero Quantitative ethnobotanical in-dexes such as RFC and CI were calculated in this study to

analyze the ethnobotanical information According to RFCvalues Croton macrostachyus (01) Vernonia auriculifera(004) Clematis simensis (004) and Acmella caulirhiza(004) are the most frequently cited among all reportedplants Croton macrostachyus (016) Dorstenia barnimiana(012) and Aloe spp (008) rank 1st 2nd and 3rd in positionrespectively according to the CI reference Our result alsoshows that the Pearson correlation coefficient of RFC waspositively and negatively correlated to CI and UV re-spectively (Table 6)

Most of the reported remedies prepared from theseplants were either applied topically (50) or taken orally(417) )e remaining remedies were prepared to be ad-ministered either topically or orally (33) both topicallyand orally (17) and intranasally (17) Usually freshplants were finely chopped dried and pounded to powderform )en the powder of either one or the combination ofmore than one plant was either mixed with drinking water orpasted and applied topically In other cases fresh plant partswere decocted and taken orally or crushed and appliedtopically Water was the main medium in preparation ofmost remedies and additives like honey milk and butterwere also used To determine the amount of plant parts usedto prepare remedies traditional healers used spoon fin-gertip and number (in case of fresh leaves) Adverse effectsreported by respondents include vomiting diarrhea andskin ulcers

4 Discussion

Despite the rich biodiversity of the study areas broad ac-ceptability and centuries-old tradition of using traditionalmedicines the number of anticancer plants reported in thisstudy is far less than expected As it was reported by differentethnobotanical studies conducted in different parts ofEthiopia this could be attributed to the attitude of manytraditional healers to guard their indigenous medicalknowledge as a family secret and hence hesitant to share withthe researchers [13 32 73] Justifying the lower number offemale traditional healers (8 11) participated in this studythese studies also inferred that traditional healers usuallypass their knowledge to the first son of the family

In this study in agreement with the studies conducted inFiche district [35] Ghimbi district [20] and Hawassa city[17] of Ethiopia the predominant botanical familiesrecorded listing over 5 plant species each were AsteraceaeFabaceae and Lamiaceae )is could be due to the fact thatthese families are the largest in the flora of Ethiopia andEritrea [15 21 143] Moreover cytotoxicity studies con-ducted on different Mexican plants reported that the highestnumber of plant species with both in vitro and in vivoantineoplasic activities was from these families [20]

)e highest UVs recorded in this study include Aloe spp(6) Achyranthes aspera L (4) Albizia schimperiana (4) Sidaschimperiana (4) and Brucea antidysenterica (4) )e

)e present study also revealed that RFC and CI values ofsome reported species are similar However there is adistinct difference in species ranking using each index Cmacrostachyus is placed in the first position according toboth RFC and CI index)is could be due to the fact that thisspecies is mentioned by many informants and is the mostrecognized plant in most study areas Furthermore CI valueof C macrostachyus is also high suggesting the diversifieduse of the plant V auriculifera and C simensis ranked nextto C macrostachyus according to RFC index On the otherhand D barnimiana and Aloe spp ranked 2nd and 3rd by CIindex It has been suggested that UV value is a good measureof use diversity than the number of citations [144] Inagreement with this UV value in our study is driven byspecies with greatest number of use rather than those citedby more informants )e Pearson correlation coefficient ofminus036 between RFC and UV shows significant negativeassociation between the local importance of each medicinalplant and relative importance of use of plants )is result isin contrast to previous studies that reported a significantpositive correlation between RFC and UV [145 146] On theother hand there is a significant positive correlation betweenRFC and CI (r2 074 plt 0001) implying that their patternmatches across species )e species with larger RFC valueusually have higher CI such as Croton macrostachyus andVernonia auriculifera

Leaves and roots are the most commonly used plantparts in the preparation of remedies in the study districts

Similarly other ethnobotanical studies conducted in dif-ferent parts of Ethiopia also reported that leaves are thedominant plant part followed by root [16ndash18 20] )epreference towards leaves may be because leaves are themain photosynthetic organs in plants and the primaryreservoirs for secondary metabolites with medicinal values[36] In contrary to other ethnobotanical studies [17 18]where the common use of concoctions and oral route werereported in the current study majority of the reportedremedies are prepared from a single plant species and ap-plied topically

Comparative analysis of this study with other ethno-botanical surveys of plants used traditionally in treating andmanaging cancer in Ethiopia [18] Kenya [147] Cameroon[37] Nigeria [19 38] South Africa [39] and Bangladesh[148] revealed some similarities in the plants cited in thesesurveys Of the 30 plant species cited to be used in Ethiopia[18] 7 species are identified in our study Bersama abyssinicaFresen Brucea antidysenterica JF Mill Calpurnia aurea(Ait) Benth Dodonaea angustifolia Lf Dorstenia bar-nimiana Schweinf Kalanchoe petitiana A Rich and Prunusafricana (Hook f ) Kalkm

Although herbal remedies are believed by the generalpublic to be safe [46] some research findings suggestedotherwise For instance traditionally used )ai anticancerplants Ganoderma lucidum (Fr) Karst Houttuynia cordata)unb and Saussurea involucrata Matsum amp Koidz werereported to cause side effects such as headache insomniaconstipation and diarrhea [62] Similarly side effects such asvomiting diarrhea and skin necrosis associated with the useof traditional herbal remedies were reported in this andother ethnobotanical studies conducted in Ethiopia[149 150] Few side effects reported in this study ascompared to other ethnobotanical studies conducted inEthiopia could be attributed to the frequent use of thetopical route of administration Nevertheless consideringthe probability of underreporting adverse effects extensivetoxicological investigations should be conducted to protectthe public

In vitro cytotoxicity and antioxidant properties of someof the plants reported in our study have also been studiedAmong these plants potent cytotoxic activity was reportedfor knipholone anthrone isolated from Kniphofia foliosawith IC50 value that ranges between 09plusmn 01 and33plusmn 04 μgmL [89] Similarly Nibret and Wink reportedthe cytotoxic activity of the crude extract of Acokanthera

5 Conclusion

)e present study showed that traditional healers in elevendistricts of Ethiopia use different medicinal plants to managecancer-like symptoms Frequency of citation value rankedCroton macrostachyus Del Clematis simensis FresenDorstenia barnimiana Schweinf Vernonia auriculiferaHiern and Acmella caulirhiza Del as most cited plantspecies in study areas Hence based on these findings we arecurrently evaluating the in vitro antiproliferative activities ofreported medicinal plant species with a higher frequency ofcitation against human breast adenocarcinoma (MCF-7)human uterine cervical adenocarcinoma (SiSo) human lungcarcinoma (A-427) and human bladder cancer (RT-4) celllines using crystal violate assay However considering therapid disappearance of the traditional knowledge of me-dicinal plants and an urgent need for new anticancer agentsadditional studies have to be conducted to document andscientifically validate traditionally used Ethiopian anticancerplants

233 Informant Consensus Factor (ICF) Informant con-sensus factor (ICF) was calculated to determine the ho-mogeneity of the information collected about particularplant species to treat specific ailment It was estimated usingthe following formula [31]

ICF Nur minus NtNur minus 1

(3)

where Nur is the number of use reports of informants forparticular ailment category and Nt refers to the number ofspecies used for the ailment category by all informants

234 Cultural Importance Index (CI) Cultural importanceindex (CI) is calculated by the sum of the use reports (UR) ofinformants mentioning each species use (from i1 to iN) ineach use category and adding all the UR of each category(from u1 to uNC) divided by the total number of informantsN )is index is determined by the following formula [29]

A total of 53 plant species belonging to 30 families werereported for their anticancer use (Table 3) )e result of thisstudy showed that shrubs (491) herbs (339) trees(132) and climbers (38) were the main sources of po-tential anticancer medicinal plants )is study also indicatedthat leaves (567) were the most commonly used plant partsfollowed by roots (217) bark (67) stem (17) seeds(17) whole plant (17) leaves and roots (5) leaves orstem (17) and leaves or seeds (17) (Figure 3) Most of thereported plants occurred naturally in wild (962) howevercultivationwas also a source (38) Reportedmedicinal plantshave been traditionally claimed to be used to treat differenttypes of ailments including cancer However only few havebeen scientifically investigated for their antiproliferative orcytotoxic activity (Table 4) While comparing the amount anddistribution of anticancer plants in the past ten years

regardless of the study areas all respondents believed that theamount and distribution of these plants are reduced

4 Evidence-Based Complementary and Alternative Medicine

analyze the ethnobotanical information According to RFCvalues Croton macrostachyus (01) Vernonia auriculifera(004) Clematis simensis (004) and Acmella caulirhiza(004) are the most frequently cited among all reportedplants Croton macrostachyus (016) Dorstenia barnimiana(012) and Aloe spp (008) rank 1st 2nd and 3rd in positionrespectively according to the CI reference Our result alsoshows that the Pearson correlation coefficient of RFC waspositively and negatively correlated to CI and UV re-spectively (Table 6)

Most of the reported remedies prepared from theseplants were either applied topically (50) or taken orally(417) )e remaining remedies were prepared to be ad-ministered either topically or orally (33) both topicallyand orally (17) and intranasally (17) Usually freshplants were finely chopped dried and pounded to powderform )en the powder of either one or the combination ofmore than one plant was either mixed with drinking water orpasted and applied topically In other cases fresh plant partswere decocted and taken orally or crushed and appliedtopically Water was the main medium in preparation ofmost remedies and additives like honey milk and butterwere also used To determine the amount of plant parts usedto prepare remedies traditional healers used spoon fin-gertip and number (in case of fresh leaves) Adverse effectsreported by respondents include vomiting diarrhea andskin ulcers

4 Discussion

Despite the rich biodiversity of the study areas broad ac-ceptability and centuries-old tradition of using traditionalmedicines the number of anticancer plants reported in thisstudy is far less than expected As it was reported by differentethnobotanical studies conducted in different parts ofEthiopia this could be attributed to the attitude of manytraditional healers to guard their indigenous medicalknowledge as a family secret and hence hesitant to share withthe researchers [13 32 73] Justifying the lower number offemale traditional healers (8 11) participated in this studythese studies also inferred that traditional healers usuallypass their knowledge to the first son of the family

In this study in agreement with the studies conducted inFiche district [35] Ghimbi district [20] and Hawassa city[17] of Ethiopia the predominant botanical familiesrecorded listing over 5 plant species each were AsteraceaeFabaceae and Lamiaceae )is could be due to the fact thatthese families are the largest in the flora of Ethiopia andEritrea [15 21 143] Moreover cytotoxicity studies con-ducted on different Mexican plants reported that the highestnumber of plant species with both in vitro and in vivoantineoplasic activities was from these families [20]

)e highest UVs recorded in this study include Aloe spp(6) Achyranthes aspera L (4) Albizia schimperiana (4) Sidaschimperiana (4) and Brucea antidysenterica (4) )e

)e present study also revealed that RFC and CI values ofsome reported species are similar However there is adistinct difference in species ranking using each index Cmacrostachyus is placed in the first position according toboth RFC and CI index)is could be due to the fact that thisspecies is mentioned by many informants and is the mostrecognized plant in most study areas Furthermore CI valueof C macrostachyus is also high suggesting the diversifieduse of the plant V auriculifera and C simensis ranked nextto C macrostachyus according to RFC index On the otherhand D barnimiana and Aloe spp ranked 2nd and 3rd by CIindex It has been suggested that UV value is a good measureof use diversity than the number of citations [144] Inagreement with this UV value in our study is driven byspecies with greatest number of use rather than those citedby more informants )e Pearson correlation coefficient ofminus036 between RFC and UV shows significant negativeassociation between the local importance of each medicinalplant and relative importance of use of plants )is result isin contrast to previous studies that reported a significantpositive correlation between RFC and UV [145 146] On theother hand there is a significant positive correlation betweenRFC and CI (r2 074 plt 0001) implying that their patternmatches across species )e species with larger RFC valueusually have higher CI such as Croton macrostachyus andVernonia auriculifera

Leaves and roots are the most commonly used plantparts in the preparation of remedies in the study districts

Similarly other ethnobotanical studies conducted in dif-ferent parts of Ethiopia also reported that leaves are thedominant plant part followed by root [16ndash18 20] )epreference towards leaves may be because leaves are themain photosynthetic organs in plants and the primaryreservoirs for secondary metabolites with medicinal values[36] In contrary to other ethnobotanical studies [17 18]where the common use of concoctions and oral route werereported in the current study majority of the reportedremedies are prepared from a single plant species and ap-plied topically

Comparative analysis of this study with other ethno-botanical surveys of plants used traditionally in treating andmanaging cancer in Ethiopia [18] Kenya [147] Cameroon[37] Nigeria [19 38] South Africa [39] and Bangladesh[148] revealed some similarities in the plants cited in thesesurveys Of the 30 plant species cited to be used in Ethiopia[18] 7 species are identified in our study Bersama abyssinicaFresen Brucea antidysenterica JF Mill Calpurnia aurea(Ait) Benth Dodonaea angustifolia Lf Dorstenia bar-nimiana Schweinf Kalanchoe petitiana A Rich and Prunusafricana (Hook f ) Kalkm

A total of 53 plant species belonging to 30 families werereported for their anticancer use (Table 3) )e result of thisstudy showed that shrubs (491) herbs (339) trees(132) and climbers (38) were the main sources of po-tential anticancer medicinal plants )is study also indicatedthat leaves (567) were the most commonly used plant partsfollowed by roots (217) bark (67) stem (17) seeds(17) whole plant (17) leaves and roots (5) leaves orstem (17) and leaves or seeds (17) (Figure 3) Most of thereported plants occurred naturally in wild (962) howevercultivationwas also a source (38) Reportedmedicinal plantshave been traditionally claimed to be used to treat differenttypes of ailments including cancer However only few havebeen scientifically investigated for their antiproliferative orcytotoxic activity (Table 4) While comparing the amount anddistribution of anticancer plants in the past ten years

regardless of the study areas all respondents believed that theamount and distribution of these plants are reduced

In the current study the highest UVs were recorded forAloe spp (6) Albizia schimperiana (4) Sida schimperiana(4) Achyranthes aspera (4) Brucea antidysenterica (4)Cleome brachycarpa (3) Leonotis ocymifolia (3) and Prunusafricana (3) )e lowest UVs were obtained for Acokantheraschimperi Acmella caulirhiza Cineraria abyssinica andGnidia involucrata (Table 3) A total of 228 use reports havebeen documented and categorized into seven categories(Table 5) Among these other ailments (463) and skincancer (265) had the highest use reports FurthermoreICF values were also calculated and ranged from 0 to 042)e highest ICF values were recorded in other ailments(042) and breast cancer (032) followed by skin cancer(023) category (Table 5) )e other ailments categorycomprises of diseases such as stomach ache malaria wartswelling wounds evil eye toothache bleeding gastroin-testinal disorder headache bone fracture cough snakebite herpes simplex tonsillitis hypertension dandrufffever and hemorrhoid)e ICF value of the remaining fourcategories (lung cancer colon cancer cervical cancer andthroat cancer) was zero Quantitative ethnobotanical in-dexes such as RFC and CI were calculated in this study to

analyze the ethnobotanical information According to RFCvalues Croton macrostachyus (01) Vernonia auriculifera(004) Clematis simensis (004) and Acmella caulirhiza(004) are the most frequently cited among all reportedplants Croton macrostachyus (016) Dorstenia barnimiana(012) and Aloe spp (008) rank 1st 2nd and 3rd in positionrespectively according to the CI reference Our result alsoshows that the Pearson correlation coefficient of RFC waspositively and negatively correlated to CI and UV re-spectively (Table 6)

Most of the reported remedies prepared from theseplants were either applied topically (50) or taken orally(417) )e remaining remedies were prepared to be ad-ministered either topically or orally (33) both topicallyand orally (17) and intranasally (17) Usually freshplants were finely chopped dried and pounded to powderform )en the powder of either one or the combination ofmore than one plant was either mixed with drinking water orpasted and applied topically In other cases fresh plant partswere decocted and taken orally or crushed and appliedtopically Water was the main medium in preparation ofmost remedies and additives like honey milk and butterwere also used To determine the amount of plant parts usedto prepare remedies traditional healers used spoon fin-gertip and number (in case of fresh leaves) Adverse effectsreported by respondents include vomiting diarrhea andskin ulcers

4 Discussion

Despite the rich biodiversity of the study areas broad ac-ceptability and centuries-old tradition of using traditionalmedicines the number of anticancer plants reported in thisstudy is far less than expected As it was reported by differentethnobotanical studies conducted in different parts ofEthiopia this could be attributed to the attitude of manytraditional healers to guard their indigenous medicalknowledge as a family secret and hence hesitant to share withthe researchers [13 32 73] Justifying the lower number offemale traditional healers (8 11) participated in this studythese studies also inferred that traditional healers usuallypass their knowledge to the first son of the family

In this study in agreement with the studies conducted inFiche district [35] Ghimbi district [20] and Hawassa city[17] of Ethiopia the predominant botanical familiesrecorded listing over 5 plant species each were AsteraceaeFabaceae and Lamiaceae )is could be due to the fact thatthese families are the largest in the flora of Ethiopia andEritrea [15 21 143] Moreover cytotoxicity studies con-ducted on different Mexican plants reported that the highestnumber of plant species with both in vitro and in vivoantineoplasic activities was from these families [20]

)e highest UVs recorded in this study include Aloe spp(6) Achyranthes aspera L (4) Albizia schimperiana (4) Sidaschimperiana (4) and Brucea antidysenterica (4) )e

)e present study also revealed that RFC and CI values ofsome reported species are similar However there is adistinct difference in species ranking using each index Cmacrostachyus is placed in the first position according toboth RFC and CI index)is could be due to the fact that thisspecies is mentioned by many informants and is the mostrecognized plant in most study areas Furthermore CI valueof C macrostachyus is also high suggesting the diversifieduse of the plant V auriculifera and C simensis ranked nextto C macrostachyus according to RFC index On the otherhand D barnimiana and Aloe spp ranked 2nd and 3rd by CIindex It has been suggested that UV value is a good measureof use diversity than the number of citations [144] Inagreement with this UV value in our study is driven byspecies with greatest number of use rather than those citedby more informants )e Pearson correlation coefficient ofminus036 between RFC and UV shows significant negativeassociation between the local importance of each medicinalplant and relative importance of use of plants )is result isin contrast to previous studies that reported a significantpositive correlation between RFC and UV [145 146] On theother hand there is a significant positive correlation betweenRFC and CI (r2 074 plt 0001) implying that their patternmatches across species )e species with larger RFC valueusually have higher CI such as Croton macrostachyus andVernonia auriculifera

Leaves and roots are the most commonly used plantparts in the preparation of remedies in the study districts

Similarly other ethnobotanical studies conducted in dif-ferent parts of Ethiopia also reported that leaves are thedominant plant part followed by root [16ndash18 20] )epreference towards leaves may be because leaves are themain photosynthetic organs in plants and the primaryreservoirs for secondary metabolites with medicinal values[36] In contrary to other ethnobotanical studies [17 18]where the common use of concoctions and oral route werereported in the current study majority of the reportedremedies are prepared from a single plant species and ap-plied topically

Comparative analysis of this study with other ethno-botanical surveys of plants used traditionally in treating andmanaging cancer in Ethiopia [18] Kenya [147] Cameroon[37] Nigeria [19 38] South Africa [39] and Bangladesh[148] revealed some similarities in the plants cited in thesesurveys Of the 30 plant species cited to be used in Ethiopia[18] 7 species are identified in our study Bersama abyssinicaFresen Brucea antidysenterica JF Mill Calpurnia aurea(Ait) Benth Dodonaea angustifolia Lf Dorstenia bar-nimiana Schweinf Kalanchoe petitiana A Rich and Prunusafricana (Hook f ) Kalkm

Although herbal remedies are believed by the generalpublic to be safe [46] some research findings suggestedotherwise For instance traditionally used )ai anticancerplants Ganoderma lucidum (Fr) Karst Houttuynia cordata)unb and Saussurea involucrata Matsum amp Koidz werereported to cause side effects such as headache insomniaconstipation and diarrhea [62] Similarly side effects such asvomiting diarrhea and skin necrosis associated with the useof traditional herbal remedies were reported in this andother ethnobotanical studies conducted in Ethiopia[149 150] Few side effects reported in this study ascompared to other ethnobotanical studies conducted inEthiopia could be attributed to the frequent use of thetopical route of administration Nevertheless consideringthe probability of underreporting adverse effects extensivetoxicological investigations should be conducted to protectthe public

In vitro cytotoxicity and antioxidant properties of someof the plants reported in our study have also been studiedAmong these plants potent cytotoxic activity was reportedfor knipholone anthrone isolated from Kniphofia foliosawith IC50 value that ranges between 09plusmn 01 and33plusmn 04 μgmL [89] Similarly Nibret and Wink reportedthe cytotoxic activity of the crude extract of Acokanthera

5 Conclusion

)e present study showed that traditional healers in elevendistricts of Ethiopia use different medicinal plants to managecancer-like symptoms Frequency of citation value rankedCroton macrostachyus Del Clematis simensis FresenDorstenia barnimiana Schweinf Vernonia auriculiferaHiern and Acmella caulirhiza Del as most cited plantspecies in study areas Hence based on these findings we arecurrently evaluating the in vitro antiproliferative activities ofreported medicinal plant species with a higher frequency ofcitation against human breast adenocarcinoma (MCF-7)human uterine cervical adenocarcinoma (SiSo) human lungcarcinoma (A-427) and human bladder cancer (RT-4) celllines using crystal violate assay However considering therapid disappearance of the traditional knowledge of me-dicinal plants and an urgent need for new anticancer agentsadditional studies have to be conducted to document andscientifically validate traditionally used Ethiopian anticancerplants

analyze the ethnobotanical information According to RFCvalues Croton macrostachyus (01) Vernonia auriculifera(004) Clematis simensis (004) and Acmella caulirhiza(004) are the most frequently cited among all reportedplants Croton macrostachyus (016) Dorstenia barnimiana(012) and Aloe spp (008) rank 1st 2nd and 3rd in positionrespectively according to the CI reference Our result alsoshows that the Pearson correlation coefficient of RFC waspositively and negatively correlated to CI and UV re-spectively (Table 6)

Most of the reported remedies prepared from theseplants were either applied topically (50) or taken orally(417) )e remaining remedies were prepared to be ad-ministered either topically or orally (33) both topicallyand orally (17) and intranasally (17) Usually freshplants were finely chopped dried and pounded to powderform )en the powder of either one or the combination ofmore than one plant was either mixed with drinking water orpasted and applied topically In other cases fresh plant partswere decocted and taken orally or crushed and appliedtopically Water was the main medium in preparation ofmost remedies and additives like honey milk and butterwere also used To determine the amount of plant parts usedto prepare remedies traditional healers used spoon fin-gertip and number (in case of fresh leaves) Adverse effectsreported by respondents include vomiting diarrhea andskin ulcers

4 Discussion

Despite the rich biodiversity of the study areas broad ac-ceptability and centuries-old tradition of using traditionalmedicines the number of anticancer plants reported in thisstudy is far less than expected As it was reported by differentethnobotanical studies conducted in different parts ofEthiopia this could be attributed to the attitude of manytraditional healers to guard their indigenous medicalknowledge as a family secret and hence hesitant to share withthe researchers [13 32 73] Justifying the lower number offemale traditional healers (8 11) participated in this studythese studies also inferred that traditional healers usuallypass their knowledge to the first son of the family

In this study in agreement with the studies conducted inFiche district [35] Ghimbi district [20] and Hawassa city[17] of Ethiopia the predominant botanical familiesrecorded listing over 5 plant species each were AsteraceaeFabaceae and Lamiaceae )is could be due to the fact thatthese families are the largest in the flora of Ethiopia andEritrea [15 21 143] Moreover cytotoxicity studies con-ducted on different Mexican plants reported that the highestnumber of plant species with both in vitro and in vivoantineoplasic activities was from these families [20]

)e highest UVs recorded in this study include Aloe spp(6) Achyranthes aspera L (4) Albizia schimperiana (4) Sidaschimperiana (4) and Brucea antidysenterica (4) )e

)e present study also revealed that RFC and CI values ofsome reported species are similar However there is adistinct difference in species ranking using each index Cmacrostachyus is placed in the first position according toboth RFC and CI index)is could be due to the fact that thisspecies is mentioned by many informants and is the mostrecognized plant in most study areas Furthermore CI valueof C macrostachyus is also high suggesting the diversifieduse of the plant V auriculifera and C simensis ranked nextto C macrostachyus according to RFC index On the otherhand D barnimiana and Aloe spp ranked 2nd and 3rd by CIindex It has been suggested that UV value is a good measureof use diversity than the number of citations [144] Inagreement with this UV value in our study is driven byspecies with greatest number of use rather than those citedby more informants )e Pearson correlation coefficient ofminus036 between RFC and UV shows significant negativeassociation between the local importance of each medicinalplant and relative importance of use of plants )is result isin contrast to previous studies that reported a significantpositive correlation between RFC and UV [145 146] On theother hand there is a significant positive correlation betweenRFC and CI (r2 074 plt 0001) implying that their patternmatches across species )e species with larger RFC valueusually have higher CI such as Croton macrostachyus andVernonia auriculifera

Leaves and roots are the most commonly used plantparts in the preparation of remedies in the study districts

Similarly other ethnobotanical studies conducted in dif-ferent parts of Ethiopia also reported that leaves are thedominant plant part followed by root [16ndash18 20] )epreference towards leaves may be because leaves are themain photosynthetic organs in plants and the primaryreservoirs for secondary metabolites with medicinal values[36] In contrary to other ethnobotanical studies [17 18]where the common use of concoctions and oral route werereported in the current study majority of the reportedremedies are prepared from a single plant species and ap-plied topically

Comparative analysis of this study with other ethno-botanical surveys of plants used traditionally in treating andmanaging cancer in Ethiopia [18] Kenya [147] Cameroon[37] Nigeria [19 38] South Africa [39] and Bangladesh[148] revealed some similarities in the plants cited in thesesurveys Of the 30 plant species cited to be used in Ethiopia[18] 7 species are identified in our study Bersama abyssinicaFresen Brucea antidysenterica JF Mill Calpurnia aurea(Ait) Benth Dodonaea angustifolia Lf Dorstenia bar-nimiana Schweinf Kalanchoe petitiana A Rich and Prunusafricana (Hook f ) Kalkm

)e present study showed that traditional healers in elevendistricts of Ethiopia use different medicinal plants to managecancer-like symptoms Frequency of citation value rankedCroton macrostachyus Del Clematis simensis FresenDorstenia barnimiana Schweinf Vernonia auriculiferaHiern and Acmella caulirhiza Del as most cited plantspecies in study areas Hence based on these findings we arecurrently evaluating the in vitro antiproliferative activities ofreported medicinal plant species with a higher frequency ofcitation against human breast adenocarcinoma (MCF-7)human uterine cervical adenocarcinoma (SiSo) human lungcarcinoma (A-427) and human bladder cancer (RT-4) celllines using crystal violate assay However considering therapid disappearance of the traditional knowledge of me-dicinal plants and an urgent need for new anticancer agentsadditional studies have to be conducted to document andscientifically validate traditionally used Ethiopian anticancerplants

)e present study also revealed that RFC and CI values ofsome reported species are similar However there is adistinct difference in species ranking using each index Cmacrostachyus is placed in the first position according toboth RFC and CI index)is could be due to the fact that thisspecies is mentioned by many informants and is the mostrecognized plant in most study areas Furthermore CI valueof C macrostachyus is also high suggesting the diversifieduse of the plant V auriculifera and C simensis ranked nextto C macrostachyus according to RFC index On the otherhand D barnimiana and Aloe spp ranked 2nd and 3rd by CIindex It has been suggested that UV value is a good measureof use diversity than the number of citations [144] Inagreement with this UV value in our study is driven byspecies with greatest number of use rather than those citedby more informants )e Pearson correlation coefficient ofminus036 between RFC and UV shows significant negativeassociation between the local importance of each medicinalplant and relative importance of use of plants )is result isin contrast to previous studies that reported a significantpositive correlation between RFC and UV [145 146] On theother hand there is a significant positive correlation betweenRFC and CI (r2 074 plt 0001) implying that their patternmatches across species )e species with larger RFC valueusually have higher CI such as Croton macrostachyus andVernonia auriculifera

Leaves and roots are the most commonly used plantparts in the preparation of remedies in the study districts

Similarly other ethnobotanical studies conducted in dif-ferent parts of Ethiopia also reported that leaves are thedominant plant part followed by root [16ndash18 20] )epreference towards leaves may be because leaves are themain photosynthetic organs in plants and the primaryreservoirs for secondary metabolites with medicinal values[36] In contrary to other ethnobotanical studies [17 18]where the common use of concoctions and oral route werereported in the current study majority of the reportedremedies are prepared from a single plant species and ap-plied topically

Comparative analysis of this study with other ethno-botanical surveys of plants used traditionally in treating andmanaging cancer in Ethiopia [18] Kenya [147] Cameroon[37] Nigeria [19 38] South Africa [39] and Bangladesh[148] revealed some similarities in the plants cited in thesesurveys Of the 30 plant species cited to be used in Ethiopia[18] 7 species are identified in our study Bersama abyssinicaFresen Brucea antidysenterica JF Mill Calpurnia aurea(Ait) Benth Dodonaea angustifolia Lf Dorstenia bar-nimiana Schweinf Kalanchoe petitiana A Rich and Prunusafricana (Hook f ) Kalkm

)e present study also revealed that RFC and CI values ofsome reported species are similar However there is adistinct difference in species ranking using each index Cmacrostachyus is placed in the first position according toboth RFC and CI index)is could be due to the fact that thisspecies is mentioned by many informants and is the mostrecognized plant in most study areas Furthermore CI valueof C macrostachyus is also high suggesting the diversifieduse of the plant V auriculifera and C simensis ranked nextto C macrostachyus according to RFC index On the otherhand D barnimiana and Aloe spp ranked 2nd and 3rd by CIindex It has been suggested that UV value is a good measureof use diversity than the number of citations [144] Inagreement with this UV value in our study is driven byspecies with greatest number of use rather than those citedby more informants )e Pearson correlation coefficient ofminus036 between RFC and UV shows significant negativeassociation between the local importance of each medicinalplant and relative importance of use of plants )is result isin contrast to previous studies that reported a significantpositive correlation between RFC and UV [145 146] On theother hand there is a significant positive correlation betweenRFC and CI (r2 074 plt 0001) implying that their patternmatches across species )e species with larger RFC valueusually have higher CI such as Croton macrostachyus andVernonia auriculifera

Leaves and roots are the most commonly used plantparts in the preparation of remedies in the study districts

Similarly other ethnobotanical studies conducted in dif-ferent parts of Ethiopia also reported that leaves are thedominant plant part followed by root [16ndash18 20] )epreference towards leaves may be because leaves are themain photosynthetic organs in plants and the primaryreservoirs for secondary metabolites with medicinal values[36] In contrary to other ethnobotanical studies [17 18]where the common use of concoctions and oral route werereported in the current study majority of the reportedremedies are prepared from a single plant species and ap-plied topically

Comparative analysis of this study with other ethno-botanical surveys of plants used traditionally in treating andmanaging cancer in Ethiopia [18] Kenya [147] Cameroon[37] Nigeria [19 38] South Africa [39] and Bangladesh[148] revealed some similarities in the plants cited in thesesurveys Of the 30 plant species cited to be used in Ethiopia[18] 7 species are identified in our study Bersama abyssinicaFresen Brucea antidysenterica JF Mill Calpurnia aurea(Ait) Benth Dodonaea angustifolia Lf Dorstenia bar-nimiana Schweinf Kalanchoe petitiana A Rich and Prunusafricana (Hook f ) Kalkm

)e present study also revealed that RFC and CI values ofsome reported species are similar However there is adistinct difference in species ranking using each index Cmacrostachyus is placed in the first position according toboth RFC and CI index)is could be due to the fact that thisspecies is mentioned by many informants and is the mostrecognized plant in most study areas Furthermore CI valueof C macrostachyus is also high suggesting the diversifieduse of the plant V auriculifera and C simensis ranked nextto C macrostachyus according to RFC index On the otherhand D barnimiana and Aloe spp ranked 2nd and 3rd by CIindex It has been suggested that UV value is a good measureof use diversity than the number of citations [144] Inagreement with this UV value in our study is driven byspecies with greatest number of use rather than those citedby more informants )e Pearson correlation coefficient ofminus036 between RFC and UV shows significant negativeassociation between the local importance of each medicinalplant and relative importance of use of plants )is result isin contrast to previous studies that reported a significantpositive correlation between RFC and UV [145 146] On theother hand there is a significant positive correlation betweenRFC and CI (r2 074 plt 0001) implying that their patternmatches across species )e species with larger RFC valueusually have higher CI such as Croton macrostachyus andVernonia auriculifera

Leaves and roots are the most commonly used plantparts in the preparation of remedies in the study districts

Similarly other ethnobotanical studies conducted in dif-ferent parts of Ethiopia also reported that leaves are thedominant plant part followed by root [16ndash18 20] )epreference towards leaves may be because leaves are themain photosynthetic organs in plants and the primaryreservoirs for secondary metabolites with medicinal values[36] In contrary to other ethnobotanical studies [17 18]where the common use of concoctions and oral route werereported in the current study majority of the reportedremedies are prepared from a single plant species and ap-plied topically

Comparative analysis of this study with other ethno-botanical surveys of plants used traditionally in treating andmanaging cancer in Ethiopia [18] Kenya [147] Cameroon[37] Nigeria [19 38] South Africa [39] and Bangladesh[148] revealed some similarities in the plants cited in thesesurveys Of the 30 plant species cited to be used in Ethiopia[18] 7 species are identified in our study Bersama abyssinicaFresen Brucea antidysenterica JF Mill Calpurnia aurea(Ait) Benth Dodonaea angustifolia Lf Dorstenia bar-nimiana Schweinf Kalanchoe petitiana A Rich and Prunusafricana (Hook f ) Kalkm

)e present study showed that traditional healers in elevendistricts of Ethiopia use different medicinal plants to managecancer-like symptoms Frequency of citation value rankedCroton macrostachyus Del Clematis simensis FresenDorstenia barnimiana Schweinf Vernonia auriculiferaHiern and Acmella caulirhiza Del as most cited plantspecies in study areas Hence based on these findings we arecurrently evaluating the in vitro antiproliferative activities ofreported medicinal plant species with a higher frequency ofcitation against human breast adenocarcinoma (MCF-7)human uterine cervical adenocarcinoma (SiSo) human lungcarcinoma (A-427) and human bladder cancer (RT-4) celllines using crystal violate assay However considering therapid disappearance of the traditional knowledge of me-dicinal plants and an urgent need for new anticancer agentsadditional studies have to be conducted to document andscientifically validate traditionally used Ethiopian anticancerplants

)e present study also revealed that RFC and CI values ofsome reported species are similar However there is adistinct difference in species ranking using each index Cmacrostachyus is placed in the first position according toboth RFC and CI index)is could be due to the fact that thisspecies is mentioned by many informants and is the mostrecognized plant in most study areas Furthermore CI valueof C macrostachyus is also high suggesting the diversifieduse of the plant V auriculifera and C simensis ranked nextto C macrostachyus according to RFC index On the otherhand D barnimiana and Aloe spp ranked 2nd and 3rd by CIindex It has been suggested that UV value is a good measureof use diversity than the number of citations [144] Inagreement with this UV value in our study is driven byspecies with greatest number of use rather than those citedby more informants )e Pearson correlation coefficient ofminus036 between RFC and UV shows significant negativeassociation between the local importance of each medicinalplant and relative importance of use of plants )is result isin contrast to previous studies that reported a significantpositive correlation between RFC and UV [145 146] On theother hand there is a significant positive correlation betweenRFC and CI (r2 074 plt 0001) implying that their patternmatches across species )e species with larger RFC valueusually have higher CI such as Croton macrostachyus andVernonia auriculifera

Leaves and roots are the most commonly used plantparts in the preparation of remedies in the study districts

Similarly other ethnobotanical studies conducted in dif-ferent parts of Ethiopia also reported that leaves are thedominant plant part followed by root [16ndash18 20] )epreference towards leaves may be because leaves are themain photosynthetic organs in plants and the primaryreservoirs for secondary metabolites with medicinal values[36] In contrary to other ethnobotanical studies [17 18]where the common use of concoctions and oral route werereported in the current study majority of the reportedremedies are prepared from a single plant species and ap-plied topically

Comparative analysis of this study with other ethno-botanical surveys of plants used traditionally in treating andmanaging cancer in Ethiopia [18] Kenya [147] Cameroon[37] Nigeria [19 38] South Africa [39] and Bangladesh[148] revealed some similarities in the plants cited in thesesurveys Of the 30 plant species cited to be used in Ethiopia[18] 7 species are identified in our study Bersama abyssinicaFresen Brucea antidysenterica JF Mill Calpurnia aurea(Ait) Benth Dodonaea angustifolia Lf Dorstenia bar-nimiana Schweinf Kalanchoe petitiana A Rich and Prunusafricana (Hook f ) Kalkm

Although herbal remedies are believed by the generalpublic to be safe [46] some research findings suggestedotherwise For instance traditionally used )ai anticancerplants Ganoderma lucidum (Fr) Karst Houttuynia cordata)unb and Saussurea involucrata Matsum amp Koidz werereported to cause side effects such as headache insomniaconstipation and diarrhea [62] Similarly side effects such asvomiting diarrhea and skin necrosis associated with the useof traditional herbal remedies were reported in this andother ethnobotanical studies conducted in Ethiopia[149 150] Few side effects reported in this study ascompared to other ethnobotanical studies conducted inEthiopia could be attributed to the frequent use of thetopical route of administration Nevertheless consideringthe probability of underreporting adverse effects extensivetoxicological investigations should be conducted to protectthe public

In vitro cytotoxicity and antioxidant properties of someof the plants reported in our study have also been studiedAmong these plants potent cytotoxic activity was reportedfor knipholone anthrone isolated from Kniphofia foliosawith IC50 value that ranges between 09plusmn 01 and33plusmn 04 μgmL [89] Similarly Nibret and Wink reportedthe cytotoxic activity of the crude extract of Acokanthera

5 Conclusion

)e present study showed that traditional healers in elevendistricts of Ethiopia use different medicinal plants to managecancer-like symptoms Frequency of citation value rankedCroton macrostachyus Del Clematis simensis FresenDorstenia barnimiana Schweinf Vernonia auriculiferaHiern and Acmella caulirhiza Del as most cited plantspecies in study areas Hence based on these findings we arecurrently evaluating the in vitro antiproliferative activities ofreported medicinal plant species with a higher frequency ofcitation against human breast adenocarcinoma (MCF-7)human uterine cervical adenocarcinoma (SiSo) human lungcarcinoma (A-427) and human bladder cancer (RT-4) celllines using crystal violate assay However considering therapid disappearance of the traditional knowledge of me-dicinal plants and an urgent need for new anticancer agentsadditional studies have to be conducted to document andscientifically validate traditionally used Ethiopian anticancerplants

)e present study also revealed that RFC and CI values ofsome reported species are similar However there is adistinct difference in species ranking using each index Cmacrostachyus is placed in the first position according toboth RFC and CI index)is could be due to the fact that thisspecies is mentioned by many informants and is the mostrecognized plant in most study areas Furthermore CI valueof C macrostachyus is also high suggesting the diversifieduse of the plant V auriculifera and C simensis ranked nextto C macrostachyus according to RFC index On the otherhand D barnimiana and Aloe spp ranked 2nd and 3rd by CIindex It has been suggested that UV value is a good measureof use diversity than the number of citations [144] Inagreement with this UV value in our study is driven byspecies with greatest number of use rather than those citedby more informants )e Pearson correlation coefficient ofminus036 between RFC and UV shows significant negativeassociation between the local importance of each medicinalplant and relative importance of use of plants )is result isin contrast to previous studies that reported a significantpositive correlation between RFC and UV [145 146] On theother hand there is a significant positive correlation betweenRFC and CI (r2 074 plt 0001) implying that their patternmatches across species )e species with larger RFC valueusually have higher CI such as Croton macrostachyus andVernonia auriculifera

Leaves and roots are the most commonly used plantparts in the preparation of remedies in the study districts

Similarly other ethnobotanical studies conducted in dif-ferent parts of Ethiopia also reported that leaves are thedominant plant part followed by root [16ndash18 20] )epreference towards leaves may be because leaves are themain photosynthetic organs in plants and the primaryreservoirs for secondary metabolites with medicinal values[36] In contrary to other ethnobotanical studies [17 18]where the common use of concoctions and oral route werereported in the current study majority of the reportedremedies are prepared from a single plant species and ap-plied topically

Comparative analysis of this study with other ethno-botanical surveys of plants used traditionally in treating andmanaging cancer in Ethiopia [18] Kenya [147] Cameroon[37] Nigeria [19 38] South Africa [39] and Bangladesh[148] revealed some similarities in the plants cited in thesesurveys Of the 30 plant species cited to be used in Ethiopia[18] 7 species are identified in our study Bersama abyssinicaFresen Brucea antidysenterica JF Mill Calpurnia aurea(Ait) Benth Dodonaea angustifolia Lf Dorstenia bar-nimiana Schweinf Kalanchoe petitiana A Rich and Prunusafricana (Hook f ) Kalkm

)e present study showed that traditional healers in elevendistricts of Ethiopia use different medicinal plants to managecancer-like symptoms Frequency of citation value rankedCroton macrostachyus Del Clematis simensis FresenDorstenia barnimiana Schweinf Vernonia auriculiferaHiern and Acmella caulirhiza Del as most cited plantspecies in study areas Hence based on these findings we arecurrently evaluating the in vitro antiproliferative activities ofreported medicinal plant species with a higher frequency ofcitation against human breast adenocarcinoma (MCF-7)human uterine cervical adenocarcinoma (SiSo) human lungcarcinoma (A-427) and human bladder cancer (RT-4) celllines using crystal violate assay However considering therapid disappearance of the traditional knowledge of me-dicinal plants and an urgent need for new anticancer agentsadditional studies have to be conducted to document andscientifically validate traditionally used Ethiopian anticancerplants

)e present study also revealed that RFC and CI values ofsome reported species are similar However there is adistinct difference in species ranking using each index Cmacrostachyus is placed in the first position according toboth RFC and CI index)is could be due to the fact that thisspecies is mentioned by many informants and is the mostrecognized plant in most study areas Furthermore CI valueof C macrostachyus is also high suggesting the diversifieduse of the plant V auriculifera and C simensis ranked nextto C macrostachyus according to RFC index On the otherhand D barnimiana and Aloe spp ranked 2nd and 3rd by CIindex It has been suggested that UV value is a good measureof use diversity than the number of citations [144] Inagreement with this UV value in our study is driven byspecies with greatest number of use rather than those citedby more informants )e Pearson correlation coefficient ofminus036 between RFC and UV shows significant negativeassociation between the local importance of each medicinalplant and relative importance of use of plants )is result isin contrast to previous studies that reported a significantpositive correlation between RFC and UV [145 146] On theother hand there is a significant positive correlation betweenRFC and CI (r2 074 plt 0001) implying that their patternmatches across species )e species with larger RFC valueusually have higher CI such as Croton macrostachyus andVernonia auriculifera

Leaves and roots are the most commonly used plantparts in the preparation of remedies in the study districts

Similarly other ethnobotanical studies conducted in dif-ferent parts of Ethiopia also reported that leaves are thedominant plant part followed by root [16ndash18 20] )epreference towards leaves may be because leaves are themain photosynthetic organs in plants and the primaryreservoirs for secondary metabolites with medicinal values[36] In contrary to other ethnobotanical studies [17 18]where the common use of concoctions and oral route werereported in the current study majority of the reportedremedies are prepared from a single plant species and ap-plied topically

Comparative analysis of this study with other ethno-botanical surveys of plants used traditionally in treating andmanaging cancer in Ethiopia [18] Kenya [147] Cameroon[37] Nigeria [19 38] South Africa [39] and Bangladesh[148] revealed some similarities in the plants cited in thesesurveys Of the 30 plant species cited to be used in Ethiopia[18] 7 species are identified in our study Bersama abyssinicaFresen Brucea antidysenterica JF Mill Calpurnia aurea(Ait) Benth Dodonaea angustifolia Lf Dorstenia bar-nimiana Schweinf Kalanchoe petitiana A Rich and Prunusafricana (Hook f ) Kalkm

Although herbal remedies are believed by the generalpublic to be safe [46] some research findings suggestedotherwise For instance traditionally used )ai anticancerplants Ganoderma lucidum (Fr) Karst Houttuynia cordata)unb and Saussurea involucrata Matsum amp Koidz werereported to cause side effects such as headache insomniaconstipation and diarrhea [62] Similarly side effects such asvomiting diarrhea and skin necrosis associated with the useof traditional herbal remedies were reported in this andother ethnobotanical studies conducted in Ethiopia[149 150] Few side effects reported in this study ascompared to other ethnobotanical studies conducted inEthiopia could be attributed to the frequent use of thetopical route of administration Nevertheless consideringthe probability of underreporting adverse effects extensivetoxicological investigations should be conducted to protectthe public

In vitro cytotoxicity and antioxidant properties of someof the plants reported in our study have also been studiedAmong these plants potent cytotoxic activity was reportedfor knipholone anthrone isolated from Kniphofia foliosawith IC50 value that ranges between 09plusmn 01 and33plusmn 04 μgmL [89] Similarly Nibret and Wink reportedthe cytotoxic activity of the crude extract of Acokanthera

schimperi with IC50 value of 71 μgmL [73] Studies con-ducted on the leaves of Cineraria abyssinica [100] bark ofSenna singueana [116] and bark and leaves of Rumexnepalensis [79] also revealed potent radical scavenging ac-tivity of these plants

5 Conclusion

)e present study showed that traditional healers in elevendistricts of Ethiopia use different medicinal plants to managecancer-like symptoms Frequency of citation value rankedCroton macrostachyus Del Clematis simensis FresenDorstenia barnimiana Schweinf Vernonia auriculiferaHiern and Acmella caulirhiza Del as most cited plantspecies in study areas Hence based on these findings we arecurrently evaluating the in vitro antiproliferative activities ofreported medicinal plant species with a higher frequency ofcitation against human breast adenocarcinoma (MCF-7)human uterine cervical adenocarcinoma (SiSo) human lungcarcinoma (A-427) and human bladder cancer (RT-4) celllines using crystal violate assay However considering therapid disappearance of the traditional knowledge of me-dicinal plants and an urgent need for new anticancer agentsadditional studies have to be conducted to document andscientifically validate traditionally used Ethiopian anticancerplants

)e present study also revealed that RFC and CI values ofsome reported species are similar However there is adistinct difference in species ranking using each index Cmacrostachyus is placed in the first position according toboth RFC and CI index)is could be due to the fact that thisspecies is mentioned by many informants and is the mostrecognized plant in most study areas Furthermore CI valueof C macrostachyus is also high suggesting the diversifieduse of the plant V auriculifera and C simensis ranked nextto C macrostachyus according to RFC index On the otherhand D barnimiana and Aloe spp ranked 2nd and 3rd by CIindex It has been suggested that UV value is a good measureof use diversity than the number of citations [144] Inagreement with this UV value in our study is driven byspecies with greatest number of use rather than those citedby more informants )e Pearson correlation coefficient ofminus036 between RFC and UV shows significant negativeassociation between the local importance of each medicinalplant and relative importance of use of plants )is result isin contrast to previous studies that reported a significantpositive correlation between RFC and UV [145 146] On theother hand there is a significant positive correlation betweenRFC and CI (r2 074 plt 0001) implying that their patternmatches across species )e species with larger RFC valueusually have higher CI such as Croton macrostachyus andVernonia auriculifera

Leaves and roots are the most commonly used plantparts in the preparation of remedies in the study districts

Similarly other ethnobotanical studies conducted in dif-ferent parts of Ethiopia also reported that leaves are thedominant plant part followed by root [16ndash18 20] )epreference towards leaves may be because leaves are themain photosynthetic organs in plants and the primaryreservoirs for secondary metabolites with medicinal values[36] In contrary to other ethnobotanical studies [17 18]where the common use of concoctions and oral route werereported in the current study majority of the reportedremedies are prepared from a single plant species and ap-plied topically

Comparative analysis of this study with other ethno-botanical surveys of plants used traditionally in treating andmanaging cancer in Ethiopia [18] Kenya [147] Cameroon[37] Nigeria [19 38] South Africa [39] and Bangladesh[148] revealed some similarities in the plants cited in thesesurveys Of the 30 plant species cited to be used in Ethiopia[18] 7 species are identified in our study Bersama abyssinicaFresen Brucea antidysenterica JF Mill Calpurnia aurea(Ait) Benth Dodonaea angustifolia Lf Dorstenia bar-nimiana Schweinf Kalanchoe petitiana A Rich and Prunusafricana (Hook f ) Kalkm

Although herbal remedies are believed by the generalpublic to be safe [46] some research findings suggestedotherwise For instance traditionally used )ai anticancerplants Ganoderma lucidum (Fr) Karst Houttuynia cordata)unb and Saussurea involucrata Matsum amp Koidz werereported to cause side effects such as headache insomniaconstipation and diarrhea [62] Similarly side effects such asvomiting diarrhea and skin necrosis associated with the useof traditional herbal remedies were reported in this andother ethnobotanical studies conducted in Ethiopia[149 150] Few side effects reported in this study ascompared to other ethnobotanical studies conducted inEthiopia could be attributed to the frequent use of thetopical route of administration Nevertheless consideringthe probability of underreporting adverse effects extensivetoxicological investigations should be conducted to protectthe public

In vitro cytotoxicity and antioxidant properties of someof the plants reported in our study have also been studiedAmong these plants potent cytotoxic activity was reportedfor knipholone anthrone isolated from Kniphofia foliosawith IC50 value that ranges between 09plusmn 01 and33plusmn 04 μgmL [89] Similarly Nibret and Wink reportedthe cytotoxic activity of the crude extract of Acokanthera

5 Conclusion

)e present study showed that traditional healers in elevendistricts of Ethiopia use different medicinal plants to managecancer-like symptoms Frequency of citation value rankedCroton macrostachyus Del Clematis simensis FresenDorstenia barnimiana Schweinf Vernonia auriculiferaHiern and Acmella caulirhiza Del as most cited plantspecies in study areas Hence based on these findings we arecurrently evaluating the in vitro antiproliferative activities ofreported medicinal plant species with a higher frequency ofcitation against human breast adenocarcinoma (MCF-7)human uterine cervical adenocarcinoma (SiSo) human lungcarcinoma (A-427) and human bladder cancer (RT-4) celllines using crystal violate assay However considering therapid disappearance of the traditional knowledge of me-dicinal plants and an urgent need for new anticancer agentsadditional studies have to be conducted to document andscientifically validate traditionally used Ethiopian anticancerplants

)e present study also revealed that RFC and CI values ofsome reported species are similar However there is adistinct difference in species ranking using each index Cmacrostachyus is placed in the first position according toboth RFC and CI index)is could be due to the fact that thisspecies is mentioned by many informants and is the mostrecognized plant in most study areas Furthermore CI valueof C macrostachyus is also high suggesting the diversifieduse of the plant V auriculifera and C simensis ranked nextto C macrostachyus according to RFC index On the otherhand D barnimiana and Aloe spp ranked 2nd and 3rd by CIindex It has been suggested that UV value is a good measureof use diversity than the number of citations [144] Inagreement with this UV value in our study is driven byspecies with greatest number of use rather than those citedby more informants )e Pearson correlation coefficient ofminus036 between RFC and UV shows significant negativeassociation between the local importance of each medicinalplant and relative importance of use of plants )is result isin contrast to previous studies that reported a significantpositive correlation between RFC and UV [145 146] On theother hand there is a significant positive correlation betweenRFC and CI (r2 074 plt 0001) implying that their patternmatches across species )e species with larger RFC valueusually have higher CI such as Croton macrostachyus andVernonia auriculifera

Leaves and roots are the most commonly used plantparts in the preparation of remedies in the study districts

Similarly other ethnobotanical studies conducted in dif-ferent parts of Ethiopia also reported that leaves are thedominant plant part followed by root [16ndash18 20] )epreference towards leaves may be because leaves are themain photosynthetic organs in plants and the primaryreservoirs for secondary metabolites with medicinal values[36] In contrary to other ethnobotanical studies [17 18]where the common use of concoctions and oral route werereported in the current study majority of the reportedremedies are prepared from a single plant species and ap-plied topically

Comparative analysis of this study with other ethno-botanical surveys of plants used traditionally in treating andmanaging cancer in Ethiopia [18] Kenya [147] Cameroon[37] Nigeria [19 38] South Africa [39] and Bangladesh[148] revealed some similarities in the plants cited in thesesurveys Of the 30 plant species cited to be used in Ethiopia[18] 7 species are identified in our study Bersama abyssinicaFresen Brucea antidysenterica JF Mill Calpurnia aurea(Ait) Benth Dodonaea angustifolia Lf Dorstenia bar-nimiana Schweinf Kalanchoe petitiana A Rich and Prunusafricana (Hook f ) Kalkm

Although herbal remedies are believed by the generalpublic to be safe [46] some research findings suggestedotherwise For instance traditionally used )ai anticancerplants Ganoderma lucidum (Fr) Karst Houttuynia cordata)unb and Saussurea involucrata Matsum amp Koidz werereported to cause side effects such as headache insomniaconstipation and diarrhea [62] Similarly side effects such asvomiting diarrhea and skin necrosis associated with the useof traditional herbal remedies were reported in this andother ethnobotanical studies conducted in Ethiopia[149 150] Few side effects reported in this study ascompared to other ethnobotanical studies conducted inEthiopia could be attributed to the frequent use of thetopical route of administration Nevertheless consideringthe probability of underreporting adverse effects extensivetoxicological investigations should be conducted to protectthe public

In vitro cytotoxicity and antioxidant properties of someof the plants reported in our study have also been studiedAmong these plants potent cytotoxic activity was reportedfor knipholone anthrone isolated from Kniphofia foliosawith IC50 value that ranges between 09plusmn 01 and33plusmn 04 μgmL [89] Similarly Nibret and Wink reportedthe cytotoxic activity of the crude extract of Acokanthera

5 Conclusion

)e present study showed that traditional healers in elevendistricts of Ethiopia use different medicinal plants to managecancer-like symptoms Frequency of citation value rankedCroton macrostachyus Del Clematis simensis FresenDorstenia barnimiana Schweinf Vernonia auriculiferaHiern and Acmella caulirhiza Del as most cited plantspecies in study areas Hence based on these findings we arecurrently evaluating the in vitro antiproliferative activities ofreported medicinal plant species with a higher frequency ofcitation against human breast adenocarcinoma (MCF-7)human uterine cervical adenocarcinoma (SiSo) human lungcarcinoma (A-427) and human bladder cancer (RT-4) celllines using crystal violate assay However considering therapid disappearance of the traditional knowledge of me-dicinal plants and an urgent need for new anticancer agentsadditional studies have to be conducted to document andscientifically validate traditionally used Ethiopian anticancerplants

)e present study also revealed that RFC and CI values ofsome reported species are similar However there is adistinct difference in species ranking using each index Cmacrostachyus is placed in the first position according toboth RFC and CI index)is could be due to the fact that thisspecies is mentioned by many informants and is the mostrecognized plant in most study areas Furthermore CI valueof C macrostachyus is also high suggesting the diversifieduse of the plant V auriculifera and C simensis ranked nextto C macrostachyus according to RFC index On the otherhand D barnimiana and Aloe spp ranked 2nd and 3rd by CIindex It has been suggested that UV value is a good measureof use diversity than the number of citations [144] Inagreement with this UV value in our study is driven byspecies with greatest number of use rather than those citedby more informants )e Pearson correlation coefficient ofminus036 between RFC and UV shows significant negativeassociation between the local importance of each medicinalplant and relative importance of use of plants )is result isin contrast to previous studies that reported a significantpositive correlation between RFC and UV [145 146] On theother hand there is a significant positive correlation betweenRFC and CI (r2 074 plt 0001) implying that their patternmatches across species )e species with larger RFC valueusually have higher CI such as Croton macrostachyus andVernonia auriculifera

Leaves and roots are the most commonly used plantparts in the preparation of remedies in the study districts

Similarly other ethnobotanical studies conducted in dif-ferent parts of Ethiopia also reported that leaves are thedominant plant part followed by root [16ndash18 20] )epreference towards leaves may be because leaves are themain photosynthetic organs in plants and the primaryreservoirs for secondary metabolites with medicinal values[36] In contrary to other ethnobotanical studies [17 18]where the common use of concoctions and oral route werereported in the current study majority of the reportedremedies are prepared from a single plant species and ap-plied topically

Comparative analysis of this study with other ethno-botanical surveys of plants used traditionally in treating andmanaging cancer in Ethiopia [18] Kenya [147] Cameroon[37] Nigeria [19 38] South Africa [39] and Bangladesh[148] revealed some similarities in the plants cited in thesesurveys Of the 30 plant species cited to be used in Ethiopia[18] 7 species are identified in our study Bersama abyssinicaFresen Brucea antidysenterica JF Mill Calpurnia aurea(Ait) Benth Dodonaea angustifolia Lf Dorstenia bar-nimiana Schweinf Kalanchoe petitiana A Rich and Prunusafricana (Hook f ) Kalkm

Although herbal remedies are believed by the generalpublic to be safe [46] some research findings suggestedotherwise For instance traditionally used )ai anticancerplants Ganoderma lucidum (Fr) Karst Houttuynia cordata)unb and Saussurea involucrata Matsum amp Koidz werereported to cause side effects such as headache insomniaconstipation and diarrhea [62] Similarly side effects such asvomiting diarrhea and skin necrosis associated with the useof traditional herbal remedies were reported in this andother ethnobotanical studies conducted in Ethiopia[149 150] Few side effects reported in this study ascompared to other ethnobotanical studies conducted inEthiopia could be attributed to the frequent use of thetopical route of administration Nevertheless consideringthe probability of underreporting adverse effects extensivetoxicological investigations should be conducted to protectthe public

In vitro cytotoxicity and antioxidant properties of someof the plants reported in our study have also been studiedAmong these plants potent cytotoxic activity was reportedfor knipholone anthrone isolated from Kniphofia foliosawith IC50 value that ranges between 09plusmn 01 and33plusmn 04 μgmL [89] Similarly Nibret and Wink reportedthe cytotoxic activity of the crude extract of Acokanthera

5 Conclusion

)e present study showed that traditional healers in elevendistricts of Ethiopia use different medicinal plants to managecancer-like symptoms Frequency of citation value rankedCroton macrostachyus Del Clematis simensis FresenDorstenia barnimiana Schweinf Vernonia auriculiferaHiern and Acmella caulirhiza Del as most cited plantspecies in study areas Hence based on these findings we arecurrently evaluating the in vitro antiproliferative activities ofreported medicinal plant species with a higher frequency ofcitation against human breast adenocarcinoma (MCF-7)human uterine cervical adenocarcinoma (SiSo) human lungcarcinoma (A-427) and human bladder cancer (RT-4) celllines using crystal violate assay However considering therapid disappearance of the traditional knowledge of me-dicinal plants and an urgent need for new anticancer agentsadditional studies have to be conducted to document andscientifically validate traditionally used Ethiopian anticancerplants

)e present study also revealed that RFC and CI values ofsome reported species are similar However there is adistinct difference in species ranking using each index Cmacrostachyus is placed in the first position according toboth RFC and CI index)is could be due to the fact that thisspecies is mentioned by many informants and is the mostrecognized plant in most study areas Furthermore CI valueof C macrostachyus is also high suggesting the diversifieduse of the plant V auriculifera and C simensis ranked nextto C macrostachyus according to RFC index On the otherhand D barnimiana and Aloe spp ranked 2nd and 3rd by CIindex It has been suggested that UV value is a good measureof use diversity than the number of citations [144] Inagreement with this UV value in our study is driven byspecies with greatest number of use rather than those citedby more informants )e Pearson correlation coefficient ofminus036 between RFC and UV shows significant negativeassociation between the local importance of each medicinalplant and relative importance of use of plants )is result isin contrast to previous studies that reported a significantpositive correlation between RFC and UV [145 146] On theother hand there is a significant positive correlation betweenRFC and CI (r2 074 plt 0001) implying that their patternmatches across species )e species with larger RFC valueusually have higher CI such as Croton macrostachyus andVernonia auriculifera

Leaves and roots are the most commonly used plantparts in the preparation of remedies in the study districts

Similarly other ethnobotanical studies conducted in dif-ferent parts of Ethiopia also reported that leaves are thedominant plant part followed by root [16ndash18 20] )epreference towards leaves may be because leaves are themain photosynthetic organs in plants and the primaryreservoirs for secondary metabolites with medicinal values[36] In contrary to other ethnobotanical studies [17 18]where the common use of concoctions and oral route werereported in the current study majority of the reportedremedies are prepared from a single plant species and ap-plied topically

Comparative analysis of this study with other ethno-botanical surveys of plants used traditionally in treating andmanaging cancer in Ethiopia [18] Kenya [147] Cameroon[37] Nigeria [19 38] South Africa [39] and Bangladesh[148] revealed some similarities in the plants cited in thesesurveys Of the 30 plant species cited to be used in Ethiopia[18] 7 species are identified in our study Bersama abyssinicaFresen Brucea antidysenterica JF Mill Calpurnia aurea(Ait) Benth Dodonaea angustifolia Lf Dorstenia bar-nimiana Schweinf Kalanchoe petitiana A Rich and Prunusafricana (Hook f ) Kalkm

Although herbal remedies are believed by the generalpublic to be safe [46] some research findings suggestedotherwise For instance traditionally used )ai anticancerplants Ganoderma lucidum (Fr) Karst Houttuynia cordata)unb and Saussurea involucrata Matsum amp Koidz werereported to cause side effects such as headache insomniaconstipation and diarrhea [62] Similarly side effects such asvomiting diarrhea and skin necrosis associated with the useof traditional herbal remedies were reported in this andother ethnobotanical studies conducted in Ethiopia[149 150] Few side effects reported in this study ascompared to other ethnobotanical studies conducted inEthiopia could be attributed to the frequent use of thetopical route of administration Nevertheless consideringthe probability of underreporting adverse effects extensivetoxicological investigations should be conducted to protectthe public

In vitro cytotoxicity and antioxidant properties of someof the plants reported in our study have also been studiedAmong these plants potent cytotoxic activity was reportedfor knipholone anthrone isolated from Kniphofia foliosawith IC50 value that ranges between 09plusmn 01 and33plusmn 04 μgmL [89] Similarly Nibret and Wink reportedthe cytotoxic activity of the crude extract of Acokanthera

schimperi with IC50 value of 71 μgmL [73] Studies con-ducted on the leaves of Cineraria abyssinica [100] bark ofSenna singueana [116] and bark and leaves of Rumexnepalensis [79] also revealed potent radical scavenging ac-tivity of these plants

5 Conclusion

)e present study showed that traditional healers in elevendistricts of Ethiopia use different medicinal plants to managecancer-like symptoms Frequency of citation value rankedCroton macrostachyus Del Clematis simensis FresenDorstenia barnimiana Schweinf Vernonia auriculiferaHiern and Acmella caulirhiza Del as most cited plantspecies in study areas Hence based on these findings we arecurrently evaluating the in vitro antiproliferative activities ofreported medicinal plant species with a higher frequency ofcitation against human breast adenocarcinoma (MCF-7)human uterine cervical adenocarcinoma (SiSo) human lungcarcinoma (A-427) and human bladder cancer (RT-4) celllines using crystal violate assay However considering therapid disappearance of the traditional knowledge of me-dicinal plants and an urgent need for new anticancer agentsadditional studies have to be conducted to document andscientifically validate traditionally used Ethiopian anticancerplants

)e present study also revealed that RFC and CI values ofsome reported species are similar However there is adistinct difference in species ranking using each index Cmacrostachyus is placed in the first position according toboth RFC and CI index)is could be due to the fact that thisspecies is mentioned by many informants and is the mostrecognized plant in most study areas Furthermore CI valueof C macrostachyus is also high suggesting the diversifieduse of the plant V auriculifera and C simensis ranked nextto C macrostachyus according to RFC index On the otherhand D barnimiana and Aloe spp ranked 2nd and 3rd by CIindex It has been suggested that UV value is a good measureof use diversity than the number of citations [144] Inagreement with this UV value in our study is driven byspecies with greatest number of use rather than those citedby more informants )e Pearson correlation coefficient ofminus036 between RFC and UV shows significant negativeassociation between the local importance of each medicinalplant and relative importance of use of plants )is result isin contrast to previous studies that reported a significantpositive correlation between RFC and UV [145 146] On theother hand there is a significant positive correlation betweenRFC and CI (r2 074 plt 0001) implying that their patternmatches across species )e species with larger RFC valueusually have higher CI such as Croton macrostachyus andVernonia auriculifera

Leaves and roots are the most commonly used plantparts in the preparation of remedies in the study districts

Similarly other ethnobotanical studies conducted in dif-ferent parts of Ethiopia also reported that leaves are thedominant plant part followed by root [16ndash18 20] )epreference towards leaves may be because leaves are themain photosynthetic organs in plants and the primaryreservoirs for secondary metabolites with medicinal values[36] In contrary to other ethnobotanical studies [17 18]where the common use of concoctions and oral route werereported in the current study majority of the reportedremedies are prepared from a single plant species and ap-plied topically

Comparative analysis of this study with other ethno-botanical surveys of plants used traditionally in treating andmanaging cancer in Ethiopia [18] Kenya [147] Cameroon[37] Nigeria [19 38] South Africa [39] and Bangladesh[148] revealed some similarities in the plants cited in thesesurveys Of the 30 plant species cited to be used in Ethiopia[18] 7 species are identified in our study Bersama abyssinicaFresen Brucea antidysenterica JF Mill Calpurnia aurea(Ait) Benth Dodonaea angustifolia Lf Dorstenia bar-nimiana Schweinf Kalanchoe petitiana A Rich and Prunusafricana (Hook f ) Kalkm

Although herbal remedies are believed by the generalpublic to be safe [46] some research findings suggestedotherwise For instance traditionally used )ai anticancerplants Ganoderma lucidum (Fr) Karst Houttuynia cordata)unb and Saussurea involucrata Matsum amp Koidz werereported to cause side effects such as headache insomniaconstipation and diarrhea [62] Similarly side effects such asvomiting diarrhea and skin necrosis associated with the useof traditional herbal remedies were reported in this andother ethnobotanical studies conducted in Ethiopia[149 150] Few side effects reported in this study ascompared to other ethnobotanical studies conducted inEthiopia could be attributed to the frequent use of thetopical route of administration Nevertheless consideringthe probability of underreporting adverse effects extensivetoxicological investigations should be conducted to protectthe public

In vitro cytotoxicity and antioxidant properties of someof the plants reported in our study have also been studiedAmong these plants potent cytotoxic activity was reportedfor knipholone anthrone isolated from Kniphofia foliosawith IC50 value that ranges between 09plusmn 01 and33plusmn 04 μgmL [89] Similarly Nibret and Wink reportedthe cytotoxic activity of the crude extract of Acokanthera

5 Conclusion

)e present study showed that traditional healers in elevendistricts of Ethiopia use different medicinal plants to managecancer-like symptoms Frequency of citation value rankedCroton macrostachyus Del Clematis simensis FresenDorstenia barnimiana Schweinf Vernonia auriculiferaHiern and Acmella caulirhiza Del as most cited plantspecies in study areas Hence based on these findings we arecurrently evaluating the in vitro antiproliferative activities ofreported medicinal plant species with a higher frequency ofcitation against human breast adenocarcinoma (MCF-7)human uterine cervical adenocarcinoma (SiSo) human lungcarcinoma (A-427) and human bladder cancer (RT-4) celllines using crystal violate assay However considering therapid disappearance of the traditional knowledge of me-dicinal plants and an urgent need for new anticancer agentsadditional studies have to be conducted to document andscientifically validate traditionally used Ethiopian anticancerplants

)e present study also revealed that RFC and CI values ofsome reported species are similar However there is adistinct difference in species ranking using each index Cmacrostachyus is placed in the first position according toboth RFC and CI index)is could be due to the fact that thisspecies is mentioned by many informants and is the mostrecognized plant in most study areas Furthermore CI valueof C macrostachyus is also high suggesting the diversifieduse of the plant V auriculifera and C simensis ranked nextto C macrostachyus according to RFC index On the otherhand D barnimiana and Aloe spp ranked 2nd and 3rd by CIindex It has been suggested that UV value is a good measureof use diversity than the number of citations [144] Inagreement with this UV value in our study is driven byspecies with greatest number of use rather than those citedby more informants )e Pearson correlation coefficient ofminus036 between RFC and UV shows significant negativeassociation between the local importance of each medicinalplant and relative importance of use of plants )is result isin contrast to previous studies that reported a significantpositive correlation between RFC and UV [145 146] On theother hand there is a significant positive correlation betweenRFC and CI (r2 074 plt 0001) implying that their patternmatches across species )e species with larger RFC valueusually have higher CI such as Croton macrostachyus andVernonia auriculifera

Leaves and roots are the most commonly used plantparts in the preparation of remedies in the study districts

Similarly other ethnobotanical studies conducted in dif-ferent parts of Ethiopia also reported that leaves are thedominant plant part followed by root [16ndash18 20] )epreference towards leaves may be because leaves are themain photosynthetic organs in plants and the primaryreservoirs for secondary metabolites with medicinal values[36] In contrary to other ethnobotanical studies [17 18]where the common use of concoctions and oral route werereported in the current study majority of the reportedremedies are prepared from a single plant species and ap-plied topically

Comparative analysis of this study with other ethno-botanical surveys of plants used traditionally in treating andmanaging cancer in Ethiopia [18] Kenya [147] Cameroon[37] Nigeria [19 38] South Africa [39] and Bangladesh[148] revealed some similarities in the plants cited in thesesurveys Of the 30 plant species cited to be used in Ethiopia[18] 7 species are identified in our study Bersama abyssinicaFresen Brucea antidysenterica JF Mill Calpurnia aurea(Ait) Benth Dodonaea angustifolia Lf Dorstenia bar-nimiana Schweinf Kalanchoe petitiana A Rich and Prunusafricana (Hook f ) Kalkm

Although herbal remedies are believed by the generalpublic to be safe [46] some research findings suggestedotherwise For instance traditionally used )ai anticancerplants Ganoderma lucidum (Fr) Karst Houttuynia cordata)unb and Saussurea involucrata Matsum amp Koidz werereported to cause side effects such as headache insomniaconstipation and diarrhea [62] Similarly side effects such asvomiting diarrhea and skin necrosis associated with the useof traditional herbal remedies were reported in this andother ethnobotanical studies conducted in Ethiopia[149 150] Few side effects reported in this study ascompared to other ethnobotanical studies conducted inEthiopia could be attributed to the frequent use of thetopical route of administration Nevertheless consideringthe probability of underreporting adverse effects extensivetoxicological investigations should be conducted to protectthe public

In vitro cytotoxicity and antioxidant properties of someof the plants reported in our study have also been studiedAmong these plants potent cytotoxic activity was reportedfor knipholone anthrone isolated from Kniphofia foliosawith IC50 value that ranges between 09plusmn 01 and33plusmn 04 μgmL [89] Similarly Nibret and Wink reportedthe cytotoxic activity of the crude extract of Acokanthera

schimperi with IC50 value of 71 μgmL [73] Studies con-ducted on the leaves of Cineraria abyssinica [100] bark ofSenna singueana [116] and bark and leaves of Rumexnepalensis [79] also revealed potent radical scavenging ac-tivity of these plants

5 Conclusion

)e present study showed that traditional healers in elevendistricts of Ethiopia use different medicinal plants to managecancer-like symptoms Frequency of citation value rankedCroton macrostachyus Del Clematis simensis FresenDorstenia barnimiana Schweinf Vernonia auriculiferaHiern and Acmella caulirhiza Del as most cited plantspecies in study areas Hence based on these findings we arecurrently evaluating the in vitro antiproliferative activities ofreported medicinal plant species with a higher frequency ofcitation against human breast adenocarcinoma (MCF-7)human uterine cervical adenocarcinoma (SiSo) human lungcarcinoma (A-427) and human bladder cancer (RT-4) celllines using crystal violate assay However considering therapid disappearance of the traditional knowledge of me-dicinal plants and an urgent need for new anticancer agentsadditional studies have to be conducted to document andscientifically validate traditionally used Ethiopian anticancerplants

schimperi with IC50 value of 71 μgmL [73] Studies con-ducted on the leaves of Cineraria abyssinica [100] bark ofSenna singueana [116] and bark and leaves of Rumexnepalensis [79] also revealed potent radical scavenging ac-tivity of these plants

5 Conclusion

)e present study showed that traditional healers in elevendistricts of Ethiopia use different medicinal plants to managecancer-like symptoms Frequency of citation value rankedCroton macrostachyus Del Clematis simensis FresenDorstenia barnimiana Schweinf Vernonia auriculiferaHiern and Acmella caulirhiza Del as most cited plantspecies in study areas Hence based on these findings we arecurrently evaluating the in vitro antiproliferative activities ofreported medicinal plant species with a higher frequency ofcitation against human breast adenocarcinoma (MCF-7)human uterine cervical adenocarcinoma (SiSo) human lungcarcinoma (A-427) and human bladder cancer (RT-4) celllines using crystal violate assay However considering therapid disappearance of the traditional knowledge of me-dicinal plants and an urgent need for new anticancer agentsadditional studies have to be conducted to document andscientifically validate traditionally used Ethiopian anticancerplants
