The word vamana means the act of vomiting.<ref>Monier-Williams, Monier-Williams Sanskrit- English Dictionary, 1st edition; Oxford University Press, Vamana, Page 920</ref> It is one of the five purification therapies ([[panchakarma]]). It is the best preventive measure and treatment for disorders due to vitiation of [[kapha]] [[dosha]]. [Cha.Sa.[[Sutra Sthana]] 25/40] The [[dosha]] accumulated in the upper part of the body (trunk and supraclavicular region) is evacuated by therapeutic emesis. [Cha.Sa.[[Sutra Sthana]] 20/19][Cha.Sa.[[Kalpa Sthana]] 1/4] 'Vamana' is also a therapeutic procedure to expel vitiated [[dosha]] by administration of medicine to induce vomiting. On the other hand, 'Chhardi' is a disease with a predominant feature of vomiting due to various underlying pathologies. The present article deals with vamana, i.e., therapeutic emesis.

The mixture of emetic medicines is given empty stomach. The selection of emetic medication depends upon the disease condition or status of health of the patient. The most commonly used emetic medicine is Randia dumetorum (madanaphala) and Acorus calamus (vacha). The emetic medications are given as powder, decoction or as paste mixed with honey and salt. [A.S.Sutra Sthana 27/10] There are 355 formulations described in [[Kalpa Sthana]] for therapeutic emesis.
