Ayurveda
• The traditional approach is to prescribe formulations with frequent and consistentrepetition of certain herbals individually or as a group for a variety of diseases
•The rationality of this kind of therapy was investigated scientifically and systematically by team of scientists at RRL, Jammu
![Page 6: GOLDEN TRIANGLE APPROACH Traditional Knowledge Modern ...](https://reader031.fdocuments.us/reader031/viewer/2022020620/61e336736714f660d464ac73/html5/thumbnails/6.jpg)
The ancient wisdom of Ayurveda which is embedded in the art of multi-
component therapy has beenscientifically revealed.
It could be the ability of specific plants(s) to synergise each other
for enhanced action profile. (Biological Response Modifiers)

• One of the foremost of such group of herbals which has been documented very frequently as an essential part of about 70% prescriptions is `Trikatu’ which contains three herbs in equal proportions:
Piper longumPiper nigrumZingiber officinalis

• Studies conducted at RRl, Jammu, have revealed the important role of `Trikatu’as a drug bioavailability/ bioefficacy enhancer.
• During the last 20 years a new approach of enhancement of drug bioavailability using drugs in combination with plant based substances as an adjunct was conceptualized and developed at RRL, Jammu
