The Sanskrit term “rasa” denotes a wide spectrum of meanings viz. “sap”, “juice”, “essence”, “taste, flavor”, “delight”, “charm,” and “sentiment,” etc. In Ayurveda, the term denotes taste/flavor, primary circulating nutritional fluid (ahararasa), fresh juice of plant (svarasa).In the context of rasashastra it indicates quicksilver, mercury (parada) and other precious metals. In Ayurveda, the primary taste is one of the identifying markers of the dravya. Apart from the contemporary meaning of taste, the concept of rasa has a wider pharmacological approach. The taste plays a vital role in deriving the pharmacological activity profile of the medicines.A physician, well acquainted with the classification of rasa and dosha, seldom commits blunders in ascertaining the etiology, symptomatology, and treatment of diseases.[1] This chapterdescribes concept of rasa (taste) with its applications in pharmacotherapeutics.

Etymology & derivation

rasa: masculine vocative singular stem: rasa [3]
As per “Dhatuvritti, 316” the root √rasaderives the meaning “āsvādanasnehanayoḥ (रसआस्वादनस्नेहनयोः।रसयति।रसतिइतिअपिशपि।)” [4] which may be broadly understood in the following manner: The Sanskrit “rasa” is composed of two roots “ra” means “giving” “bestowing” “granting” “yielding” and “sa” means “wisdom” “knowledge” “paradise”. Together these roots create “rasa” meaning “to grant knowledge,” “to yield happiness,” “to bestow paradise,” all of which are the “essence” of life, so the Sanskrit dictionary defines “rasa” as “essence”. This article deals with the aspect of rasa as taste/flavor.
