2Ethnopharmacological Studies

Introduction

Modern medicine vs Traditional medicinemodern medicine improved health care, high

cost and unavailability of modern medicine led to continued dependence on MPs.

“Albularyos” and their use of MPs are still widely practiced in rural areas of the country.

DOH endorses “Sampung Halamang Program”Still no systematic research strategy in

identification, characterization and evaluation of MPs used by “albularyos”.


Importance of the topicProblem: Poverty; No access to health care. Need alternative sources of medication. Increased income for farmers and significant

contribution to the national economyIncreased awareness and attention on MPs

Results of the researchCharacterization and evaluation of our biodiversityServe as baseline or database for further studiesused by DOH to evaluate health practices of

Pulilan.Exposure for the students: community based study

and explore ethnopharmacology in the Phils.

Significance of the Study


General Objective To document the different

medicinal plants prescribed by folk herbalist and its relationships to the Sampung Halamang Gamot endorsed by the Department of Health


Specific Objectives

1. To determine the most common medicinal plants being prescribed for common disease indications

2. To determine the parts, formulations and prepartions of medicinal plants being prescribed for common disease indications.

3. To identify the plants used by folk herbalists for common disease indications.


Specific Objectives

4. To determine the Informant Consensus Factor (ICF) and Fidelity Level (FL) in relation to medicinal plant use.

5. To determine which medicinal plants being used by the folk herbalists belong to the “Sampung Halamang Gamot.”

6. To determine the conformity of the folk herbalist for the use of the “Sampung Halamang Gamot” to its endorsed indications.


Scope and Limitation

Informants of the study“Albularyos” that prescribe medicinal plants as

means to cure diseases“Albularyos” necessitate credibility.

Location of the study Pulilan, Bulacan.

Indications of focusFever, cough, bronchitis, ringworm, diabetes, gout,

kidney stone, diarrhea, sore throat, diuretic, irregular menstruation, toothache, abdominal pain, arthritis, skin disease, wounds and burns.

of diseases, disorders and the promotion of good health

Folk Herbalist person especially in rural areas who used medicinal

plants and other alternative materials and procedures to heal

any kind of alternative medical practitioner referred by health care worker who is a resident of Pulilan ,Bulacan

knowledgeable about medicinal plants and prescribes and/or makes use of plants or plant parts in his treatment regimen.

- Tested the curative effects of herbal medicines

- Handed from generations to generations

- Moral support and psychological comfort from patients

- High social status and are well respected


Modern drugs- cheaper- decline of herbal medicines popularity

Philippine Institute of Traditional and Alternative Health Care (PITAHC)

“Traditional and alternative health care in the hands of the people”

- A Government owned and controlled corporation (GOCC)

- To deliver the traditional alternative health care.


Alternative Healthcare - used in the prevention, diagnosis and elimination of physical or mental disorder

Traditional Medicine Recognized by the peopleinterrelations based on culture, history,

heritage and consciousness


According to the DOH, the health sector falls short due to:

- inappropriate health delivery system - inadequate health regulatory mechanisms- poor health care financing

scientific study that correlates ethnic groups, their health practices, and how it relates to their physical habits and methodology in creating and using medicines

incorporates the social science of ethnology and the medical science of pharmacology.

it explores medicinal plants in indigenous cultures.

methods of collection, extraction, preparation – allowed safe usage of the substance and its safety record


- Documentation of indigenous medical knowledge

- Scientific study of indigenous medicines

- Search for pharmacologically unique principles from existing indigenous remedies.


- interviewing healers

- interpreting traditional terminologies into their modern counterparts

- examining patients consuming herbal remedies

- identifying the disease for which an herbal remedy is used


- Interpretation of signs and symptoms

- Clinical studies on herbs and their interaction with modern medicines

- Advising pharmacologists

- Strengthen traditional system of medicine in a community


Collection of information from local population concerning the use of regional medicinal plants, identified the most important species used and calculate the Informant consensus factor (ICF). The collection of data relied on a qualitative interview (Aburjai et al)


- 92 traditional medicine practitioners/healers were interviewed to collect information on the use of herbal treatments

- Information was also collected on the method of preparation, dose and duration along with the botanical names, family and local names of the medicinal plants (Hedge et al).


- Performed door-to-door visits in order to identify the local people with specialized knowledge on the use of the medicinal plants.

- By using the snowball method, the names of other specialists were obtained.

- Calculated the Informant consensus factor (ICF) for the data analysis.

- The rural dwellers of the community helped in collection of the information.


People who have knowledge on traditional medicine.

Individual Interviews

Open and semi-structured questions

More than one interview session took place


Local representatives help in identifying folk herbalists (Gazzaneo).

The local people guide in locating the folk herbalists (Akerreta).

The chosen folk herbalists have no scientific knowledge on the medicinal plants (Akerreta).

The interviewees are born or live most of their lives in the studied region (Akerreta).27Ethnopharmacological Studies

According to WHO, traditional medicine is still being used by 80% of the world population as part of their health care, especially those in developing countries.

Many African countries including Tanzania, depend on traditional healers who provide primary health care by taking care of people living with emerging diseases such as HIV/AIDS (Kisangau).


3 criteria of triangulation

Endorsement from Barangay Health Care Office

Confirmation from folk herbalists

Interview by researchers

BHCO refers traditional medical practitioners/folk herbalists in the area

Health Care Officers (HCO) and Barangay Health Workers (BHW)

verifies authenticity of referred folk herbalists

HCOs and BHWs fills up rubric sheet to quantitatively assess the recommended

folk herbalists

Self assessment of folk herbalists using rubric sheet facilitated by

researchers

Researchers divide themselves to 5 groups, each group interviewing 2 to 3 folk

herbalists

Following a standard questionnaire folk herbalists would be asked to provide information on indications,

parts of the plant used, preparation and route of

administration.

Researchers will also fill up a rubric sheet

Score of each folk herbalist from the 3 criteria will be averaged. A score of < 75 would indicate unreliability, whereas a score of > 75

indicates reliability and gives credibility to the folk herbalist.

Halamang Gamot• Informant Consensus Factor (ICF)• Fidelity Level (FL)• comparison between the herbal plants used

by the folk herbalists and those included in the Sampung Halamang Gamot


• Informant Consensus Factor (ICF)– will be used to identify agreements of the informants

on the reported cures for the groups ailments

ICF = (nur – nt) / (nur – 1)

• Fidelity Level (FL)– percentage of informants claiming the use of a certain

plant for the same major purpose

FL(%) = (Np / N) x 100

where Np = number of informants that claim a use of a plant species to treat a particular disease

N = number of informants that use the plants as a medicine to treat any given disease
