Shadarasa Chikitsa: An Introduction
One of the foundational concepts of Ayurveda is the doctrine of “Rasa”—meaning taste. Ayurveda recognizes that taste is not merely a sensory experience but a therapeutic tool. The ancient texts say:
“Raso vai saha” – Rasa is life itself.
“Rasatmakaṁ hi jīvitam” – Life is sustained through Rasa.
According to Ayurveda Shadarasa containing diet is balanced diet. Ayurveda identifies six primary tastes (Shad Rasa), each with distinct properties and effects on the body and mind. These six are:

Amla (Sour)
Lavana (Salty)
Katu (Pungent)
Tikta (Bitter)
