While performing the Virechana karam, the vitiated doshas are eliminated through the rectum.
The drugs used for the purgation therapy are to vitiate the doshas and bring them into the abdomen.
During the procedure, the patient is subjected to Oleation ( ingestion of medicated ghee, directly or mixed with recommended food ) first, then Fomentation (Induced Sweating therapy ), which is followed by Emesis ( induced vomiting ) and Samsarjana Karma ( diet control – post operative).
The internal Oleation is followed for three to seven days. Thereafter, a medicated steam bath is performed for three days. A light and warm diet is prescribed for the patient, a day before starting Virechana karma in ayurveda panchakarma treatment.
