<p style='text-align:justify;'>Dravya is classified into two types: rasa pradhana (dominated by rasa) and veerya- pradhana (dominated by veerya). <sup>[Chakrapani on Cha.Sa. Sutra Sthana 2/17]</sup> The dietary items (ahara dravya) are considered rasa pradhana, while medicines (aushadha) are deemed to be veerya pradhana. The aushadha are again divided into three types based on veerya, namely mild (mrudu veerya), moderate (madhyama veerya) and sharply acting (teekshna veerya) <sup>[Chakrapani on Cha.Sa. Sutra Sthana 2/17]</sup>. This can be summarised in the table given below:
