Abstract: Veerya is inherently the ultra-chemical accomplishment of the drugs that is principally of two types as per Ayurvedic lexicon-Ushna (hot) and Sheeta (cold). Veerya is given prime connotation in classics as it adopts the karma of a dravya because nir veerya dravya is prepensed as worthless. So veerya (potency) of drug exhibits an indispensable role in the treatment principles. Aims and Objectives are to analyse the veerya, exothermic and endothermic reactions plays an imperative role which is exhibited hereby taking Ayurvedic drugs as paradigm. 10 gram powder each of Masha, Kola, Kulattha, Suradaru, Rasna, Atasi, Gokshura, Kusha, Bala and Jeevanti was individually mixed with 10 ml water taken in 10 different beakers and temperature was acclaimed after 1, 3 and 5 minutes. These study shows Ushna veerya dravya unveiled accretion in the temperature from 1⁰-4⁰ f, while Sheeta veerya disported abatement in temperature varied from 1-3⁰f whilst temperature of water remaining constant So we can conclude that, Perception of Veerya can be scientifically corroborated taking exothermic reaction analysis as an intervention.
