ROLE OF PANCHAMAHABHUTA IN DRUG ACTION: A FUNDAMENTAL PERSPECTIVE OF DRAVYAGUNA

Abstract

Ayurveda presents a unique and holistic understanding of pharmacology through the concept of Panchamahabhuta, the five fundamental elements—Prithvi (earth), Ap (water), Teja (fire), Vayu (air), and Akasha (ether). Every substance (Dravya), including medicinal plants and formulations, is constituted by these elements, and their relative predominance determines the pharmacodynamic and therapeutic behavior of the drug. The principles of Rasa (taste), Guna (qualities), Virya (potency), Vipaka (post-digestive transformation), and Prabhava (specific action) are all governed by Mahabhuta composition. This elemental framework allows prediction of drug action on Dosha, Dhatu, and Mala, thereby forming the basis of rational drug selection in Ayurveda.
