→Pharmacodynamics of Vamana
Of all drugs, those that eliminate impurities from the upper part are known as emetics while those that act via the lower part are called purgatives. Or (broadly), both are collectively termed as evacuatives (or purgatives) because of their purging out excrement from the body. [4]

The ''ushna'', ''tikshna'', ''sukshma'', ''vyavayi'' and ''vikashi'' drugs, because of their vigorous ability in reaching the heart and circulating through the vessels, affect masses of impurity within the entire body, liquefying them and making them pass through large and small ducts (due to the fiery nature of such drugs) and detach them due to their sharpness. Consequently the detached masses left floating get ejected by ''udana'' (''vayu''). They get thrown upwards because of the natural composition of the drug with ''agni'' and ''vayu'' (''Mahabhutas'') and the specific potency (for emesis). When the natural composition of the drug predominates in ''jala'' and ''prithvi'' and there is specific potency (for purgation), it goes down. When both the above characters are combined it moves both ways. Thus the definition is said in brief. [5]
