Vaman-Kalpa involves the use of emetic substances which are hot, sharp and penetrative in quality. This therapy expels the impurities from the chest to the crown by facilitating the upward flow of prana,
and hence removes the excess mucus, phlegm, and bile which cause digestive and respiratory discomforts, torpor and anabolic imbalances.
Emetic substances are beneficial in chronic obesity, asthma,
chronic coughs and colds, nausea, poisoning, indigestion, fever and diarrhea.
