Astanga Hrudaya
ते रसानुरसतो रसभेदा- स्तारतम्यपरिकल्पनाय च। सम्भवन्ति गणनां समतीता दोषभेषजवशादुपयोज्याः॥४४॥
These Rasa (primary tastes) and Anurasas (secondary tastes) in their proportional (more, moderate and less) combinations become innumerable. These are to be selected and used after considering the conditions of the Dosas and drugs (and therapies).
