How would you advise?
• More than 95 % of the population in the least developing countries use herbs for health and other purposes.
• More than one third of Americans and Europeans use herbs for health purposes, spending over 7.0 billion annually.
• More than 25 % of modern pharmaceutical drugs have botanical origins.

Herbal drugs are cheaper than generic drugs !!??

Herbal drugs have been used in India for more than 4000 years.
![Page 19: Prof (Dr.) K. C. Singhal M.D., Ph.D. (Medicine), D.Sc., F.I.A.N., F.I.P.S.,F.I.A.M.S. Former Consultant WHO Center for International Drug Monitoring,](https://reader036.vdocument.in/reader036/viewer/2022081506/56649e7e5503460f94b8196f/html5/thumbnails/19.jpg)
• Glamorized discipline• Pursued by most (influenced and so called ‘Literate’)
in India and, in western countries• Backed by technological advances -investigations• Based on sound scientific reasoning – experimental
evidence; not anecdotal• Thus, Modern Medicine is an evidence-based,
techno-savvy science that seems to provide ultimate care to sick patients
![Page 20: Prof (Dr.) K. C. Singhal M.D., Ph.D. (Medicine), D.Sc., F.I.A.N., F.I.P.S.,F.I.A.M.S. Former Consultant WHO Center for International Drug Monitoring,](https://reader036.vdocument.in/reader036/viewer/2022081506/56649e7e5503460f94b8196f/html5/thumbnails/20.jpg)
• The treatment often symptomatic, costly.• Except for infective pathologies, we do not
have much to offer except palliation• Lifestyle Disorders like neurodegenerative
disorders treatment is often very disappointing and limited by adverse events
• treats the Disease (symptomatic) and not the patient ‘as a whole’ (Holistic approach)
![Page 21: Prof (Dr.) K. C. Singhal M.D., Ph.D. (Medicine), D.Sc., F.I.A.N., F.I.P.S.,F.I.A.M.S. Former Consultant WHO Center for International Drug Monitoring,](https://reader036.vdocument.in/reader036/viewer/2022081506/56649e7e5503460f94b8196f/html5/thumbnails/21.jpg)
Therapeutic Objective• The ultimate goal of every physician is to
“CURE” the disease.• Has Allopathy achieved this goal for all
ailments? No; Except for infective pathologies, we do not achieve CURE
• Most often the treatment is Symptomatic and Palliative.
• Effective & Safe Medicine

Traditional medicines
• Middle of 19th century, 80% of all medicines were herbal
• Even today 25% of drugs are derived from plant source
• Most of these drugs came from traditional lead, folk knowledge etc.
• Some of these still could not substituted despite the enormous advancement in synthetic chemistry eg. Reserpine, taxol, vincristine etc.

Reverse pharmacology
• What is required is “Scientific evidence”
• Answer lies in providing scientific validation
for efficacy and safety
• Screening based on ethnomedical and
ethnobotanical lead as chances of hitting the
target is more.
