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 kapha dosha, which dislodges the toxins mainly from the respiratory and gastrointestinal tract.
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 spring i.e. Hemant season as a preventive therapy in order to prevent disorders related to kapha.
Vamana treatment is targeted to expel increased Kapha Dosha out of the body. When Kapha dosha increases, it causes certain types of diseases – such as cold, cough etc. If the extent of Kapha increase is less, then some oral medicines can be given to suppress it.
Since Kapha is situated in the chest region, expelling it from the oral route is very easy. Hence, Vamana treatment is designed. To expel it out, first the Kapha Dosha needs to be forcefully brought from the extremities and different organs into the stomach, and then vomiting is induced.
