Abstract

‛‛Tatra Doshaharanam Adhobhagam Virechanasanjnakam’’ - Charak. Kalpa. ¼ Virechana is a therapeutic procedure by which the Doshas are eliminated through the Adhomarga i.e. Guda. Though Virechana influences Tridoshas, it mainly eliminates Pitta Dosha. Virechana Dravyas possesses the qualities of Ushna, Tikshana, Sukshma, Vyavayi, Vikasi having predominance of Prithvi, Ap Mahabhutas and by Adhobhaghara Prabhava, it performs Virechana Karma. In the present scientific era of modern technologies it is a need to re-evaluate the Karmukta of Virechana Karma in light of modern pharmacodynamics. Virechana Dravya produces bowel evacuation by neural control and functional movements. The various classifications of Virechana Dravyas and their mode of action in Ayurvedic lines in light of modern pharmacodynamics will be presented in detail in this paper. Eg. A drug which is having action on the gall bladder stimulates it to contract and expels the bile into duodenum whereby the bile salts enhances the peristalsis causing laxation which action is called as pitta Saraka possessed by Katuka Rohini [Picrorrhiza kurra].

Keywords: Pitta; Virechana; Adhobhaghara.
