AN ASSESSMENT OF VEERYA BY EXOTHERMIC AND ENDOTHERMIC REACTIONS OF TRAYUSHANA:- SHUNTI RHIZOME (ZINGIBER OFFICINALE ROSCOE), MARICHA FRUIT (PIPER NIGRUM LINN), PIPPALI FRUIT (PIPER LONGUM LINN) CHURNA” AN EXPERIMENTAL STUDY

In Ayurveda, Dravya plays a vital role in the treatment and Dravya has been positioned in second prime place in the Chikitsta Chatushpada. The therapeutic efficacy of Dravya depends on its Rasa-Panchaka, especially Veerya. Veerya is the potency of a Dravya that allows the Dravya to exhibit its action. It is the ultra-chemical action of the drug and it can be found in two kinds: 1. Usna Veerya (Hot in potency), which is Vata-Kapha Doshahara and 2. Shita Veerya (Cold in power) is Pitta Doshahara. Hence Veerya of Dravya has significant role in treatment. To determine the potency of drug, the concept of Endothermic and Exothermic reactions play an imperative role. In this experiment, Trayushana: - Shunti, Maricha, Pippali also known as Trikatu, the three indispensable drugs used in Ayurveda were taken for the assessment of Veerya. Results of this study demonstrated the Usna Veerya property of Shunti and Maricha and Anushna Veerya property of Pippali.
