Every part of the body except the head is exposed to herbal steam. This produces sweat, dilates the channels of the body, and facilitates easy removal of impurities from the system through excretory outlets like the sweat gland, kidney, and liver. When done after a treatment, it also helps the absorption of medicinal particles present in the herbal oil.

The steam bath gives greater flexibility and suppleness to the body and reduces stiffness and swelling. The body becomes light due to the elimination of excess water.
