Svedana is an ayurvedic sweat treatment, a detoxifying and soothing herbal steam bath. Plants such as castor root, barley, sesame, black gram, jujube and the drumstick plant all encourage the body to sweat more easily. Svedana is often applied after an oil massage. Sweating leads the doshas to fluidity, making it easier for it to flow out of the system. It improves peripheral circulation by vasodilatation, which opens the pores in the skin and absorbs the medicinal properties of the herbal oil, eliminates certain impurities through sweat, relieves stiffness, pain and swelling and provides lightness to the body.
