Abstract: Pharmacodynamics of dravya (substance) is explained with five fundamental principles viz. Rasa (taste), Guna (quality), V?rya (potency), Vip?ka (bio transformed) and Prabh?va (exceptional activity) collectively known as Rasapancaka (five attributes). Bridelia stipularis (L.) Blume is a folklore medicine with multiple uses. Identification of Rasapancaka of such folklore drugs is needed to incorporate them into Ayurvedic Materia Medica. The Rasa and Virya of Bridelia stipularis (L.) Blume was evaluated using Rasa analyzing Performa and endothermic and exothermic reaction respectively. The drug (2 g) was administered to 30 participants and their responses after intake of the drug were recorded. On analyzing the data it was found that the drug possesses predominantly Kashaya (astringent), Tikta (bitter) Rasa and Madhura (sweet) as anurasa (un-manifested). V?rya of the drug was found to be ??ta (coldness).
