Swedana is a steam treatment explained in Ayurvedic medical science. The word Sweda is derived from Sanskrit swid, meaning ‘to sweat or to perspire’. So swedana is the process of inducing sweat with the help of steam, generated from medicated herbal decoctions. It is the pre-operative procedure in various Ayurvedic detox therapies where the objective is to dilate the channels of the body to detach the toxins from the tissues. Ayurvedic fomentation is usually given after an oil massage.
