In this treatment, a patient is given internal and external oleation and fomentation therapies for few days. Once the toxins get liquefied and gather in upper cavities of body, the patient is given emetic medicine and decoction. This induces vomiting and helps to eliminate toxins from the body tissues. Vaman therapy is especially recommended primarily for kapha-dominated conditions such as obesity, asthma and hyperacidity.
In virechan, purgation or elimination of toxins occurs through the evacuation of the bowels. In this treatment as well, the patient is given internal and external oleation and fomentation therapies. After that, the patient is given a herbal laxative to facilitate evacuation of the bowels that helps in cleansing the body of toxins. Virechan therapy is recommended primarily for pitta-dominated conditions such as herpes zoster, jaundice, colitis, celiac disease etc.
