Swedana (sudation) therapy is a process which has a dual role in panchkarma as well as pradhan karma in relevance to panchkarma and the treatment of various vata-kaphaja and medopradoshaja vikara. Swedana helps to relief stiffness heaviness and coldness of the body and makes the body to perspire. It removes toxins from the body through hair follicles present all over the skin .The perspiration brought about by the swedana is more than the normal. Swedana is preventive, supportive as well as therapeutic. Acharya charak has mentioned the root of origin of swedavaha srotas (channels) lies in Meda (fat, lipids, Adipose tissue) and lomakoop (minute pores of the skin located around base of hair follicles). Sweda is considered to be excreta (Mala) of meda dhatu. The root of origin of medovaha srotas (channels) are Vrikka (kidney) and vapvahana(peritoneal membrane). The Vrikka (kidney) is originated from prasada bhag of Rakta (Blood) and meda. In Chronic kidney disease (CKD), the hemodynamics of the kidney is hampered which leads to accumulation of toxins and unltered excretory wastes. So with the help of swedana the hemodynamics of kidney and the body is improved which facilitates the expulsion of accumulated toxins through activation of sweat glands to produce more sweat. It causes apana vata anulomana which further facilitates micturition. In this article you will come to know the relevance of swedana in chronic kidney disease (CKD) patients.
