ABSTRACT

Ayurveda, the science of life is based on three pillars-hetu, linga and aushada. The two main goals of Ayurveda are– 1. To protect the health of a healthy person. 2. To eradicate the disease. These two goals will be achieved with the help of dravya. According to Charaka there is no any substance in the world which may not be used as a medicine. The knowledge of dravya is very important, not only in Ahara (food) aspect but also in the Aushadha (drug) aspect because of its panchabhoutikta. If the drug is not known then it can be compare with poision, fire, and thunderbolt. But if anyone knows about it then it acts like a nectar. (Raj nighantu). Rasa was defined by Acharya Charaka as the special sense known through the rasana or rasanenedriya (tongue or taste buds)6. But after observing all the concept of rasa, it could be defined as ‘It is the object of gustatory sense organ which is located in the tongue. It is not only the perception of taste but is an indicator of the composition, properties & probable action of the dravya’.
