Vamana is a therapeutic procedure to eliminate the vitiated Kapha Dosha through vomiting. Kapha is predominating in the upper portion of the body hence in disease like cough, asthma, and difficult breathing etc Vamana is preferred. Vamana is mainly intended for Kapha Dosha but it eliminates also Pitta Dosha. Shodhana Chikitsa is especially indicated to flush out the vitiated Doshas which converts in to Mala, because of various interactions taking place in the body right from the accumulation of Doshas. These malas cause immense damage to the body residing in side, and there toxins are eliminated through the Vamana induced by the Vaman Producer.

Vamana karma is not only indicated for curative purpose, also it is prescribed for maintenance of health as- ‘Seasonal Sodhana’. It is done in ,where in Kapha Dosha is in aggravating phase.

Of all the five Panchakarma therapies, this is the most precarious; one can strain to vomit and damage the nerve reflexes. With proper guidance one learns the method for oneself or consults a qualified Panchakarma specialist. It is done regularly to cleanse the stomach and remove ama (toxins) and mucus from the nadis (channels) and chest.

Two types of Vamana herbs exist:

  • Vamaka Drugs: - Those that induce vomiting (vamaka). They are hot (circulating throughout the body, loosening and liquefying), sharp (separating qualities), and penetrating (throughout the body). Therapies include kutaj, salt water, liquorice, and vacha.
  • Vamanopaga Drugs: - Herbs that further help or enhance the inducing herbs (vamanopaga). Herbs include pippali, amalaki, rock salt, neem, and madana phal.

Mode of action of Vamana herbs:-

As Vamaka Drugs posses the qualities like ushna (hot), Tikshna(irritating), sukshma (deep penetrating) Vyavayi (spreading speedily)and acts by their own potency and reach throughout the body channels, break up the hard masses, which are softened by the purva karma (snehana and swedana) producers, sticking on in all the small and big pores inside. These Vamana drugs by his own qualities cut off their adhesions and make them move out drop by drop without any further adherence, just like water moves inside a pot smeared with oil and collect inside the stomach. These drugs have Agni and Vayu panchbhoutika constitution so their action in upwards movements give rise to reflex vomiting.    

Vamana is not recommended for pregnant women, with other Váyu excesses, before oleation, when hungry, under constant grief, for children, elderly, emaciated, Váyu obesity, wounded, heart problems, high blood pressure, and vomiting (Pitta or Váyu imbalances). It is not practiced with weakness, enlarged spleen or abdomen, blindness, intestinal parasites, upward movement of Vayu (reverse peristalsis) bleeding, immediately after an enema, loss of speech, urine retention, or abdominal tumours.
