Swedana is a steam treatment explained in Ayurvedic medical science. The word Sweda is derived from Sanskrit said,  meaning ‘to sweat or to perspire’. So Swedan is the process of inducing sweat with the help of steam, generated from medicated herbal decoctions. 

It means medicated steam is given to body. It reduces pain as well as stiffness. For Panchakarma therapy like Vaman & Virechan, Swedan is used as pre procedure.
