EXPLORING THE PHARMACODYNAMICS OF VIRECHANA KARMA: AYURVEDIC PRINCIPLES AND MODERN SCIENCE

Abstract

Virechana is a therapeutic measure in Ayurveda aimed at expelling Doshas, particularly Pitta, through the downward route. It is particularly beneficial in Pittaja Vikara since Virechana substances possess Ushna, Tikshana, Sukshma, Vyavayi and Vikashi properties. Virechana substances also offer predominance of the Prithvi and Jala elements. These substances showed Adhobhaghara effects which involve downward purgative action. Virechana drugs, due to their potency and inherent effect, reach the Hridaya and circulate throughout the channels. This action also facilitated by their Sukshma and Vyavayi properties. The Ushna quality of these drugs helps in Vishyandana of the accumulated Doshas. Tikshana and Vikashi properties cause Chhedana of the vitiated Dosha. These processes prepare Pitta Dosha, for expulsion and removes aggravated Doshas thus halts the progression of disease associated with Pittaja Vikara. Virechana as detoxifying procedure indicated in many conditions such as Pandu, Kamala, Kustha, Visarpa and Raktapitta, etc. This article explores the mode of action of Virechan Karma from both Ayurvedic and modern scientific perspectives.
