Ayurveda believes that in pitta prakop (aggravation of pitta— one of the basic body constituents), virechan helps in eliminating the cause of aggravation and in re-establishing a status of health. When pitta crosses its normal limits, it accumulates in the dhatu (body tissues) and in the strotasa (body channels). This accumulated pitta is liquefied, directed towards an outlet and then pushed out of the body by means of virechan. This Therapatic purgation is useful mainly in skin diseases like psoriasis, lichen planus, eczima, pimples, rash, alergy etc. & acidity, indigetion, excess vomiting, piles, fishers, fistula, diseases of reproductive system, burning sensation, pitta predominant diseases.
