Physiological and biochemical changes with Vamana procedure.

Vamana Karma (therapeutic emesis) primarily a Samshodhana Karma (purification procedure) is one of the five Pradhana Karmas (chief procedures) of Panchakarma. It is mentioned in Ayurvedic texts that a person after Samyak Vamana (proper Vamana) experiences lightness of the body, Hrit (precordium), Kantha (throat/voice), and Shirah (head) and weakness. This procedure is effectively used in healthy and ailing persons for purification of body and extraction of Doshas (especially Kapha) in Ayurvedic system. It has been found worth to observe the physiological and biochemical changes during Vamana and after the procedure to understand the effect/safety margins of the procedure in healthy volunteers.
