In this Panchakarma treatment, vomiting is induced by oral administration of herbal emetics to remove the accumulated doshas especially vitiated Kaphadosha from the body.

Vaman is one of the five therapies of panchakarma in Ayurveda. Vaman means therapeutic vomiting which is a medicated emesis.
This treatment is done for the aggravated kaphadosha, which dislodges the toxins mainly from the respiratory and gastrointestinal tract.
This therapy is also done for preventive & curative purposes. Ayurveda believes that different seasons have a great influence in the aggravation of doshas, ex: Kapha in hemant (spring season), pitta in Sharada(winter)season and vata in greeshma(summers) season.
Hence one can adopt Vaman therapy in Springi.ehemant season as a preventive therapy in order to prevent disorders related to kapha.
