Vamana or induced emesis is one of the five cleansing methods of Panchakarma Chikitsa. It is performed to subdue augmented Kapha Dosha. Giving decoction of medicinal herbs for ingestion in large amounts induces emesis. Before the main procedure (Vaman), there are three preparatory procedures to be employed. They are: Paachan (Digestion), Snehan (Oleation therapy) and Swedan (diaphoresis).
