Kinds of sweating; heat and steam sweating

Sweating is of four kinds: heat (tapa), steam (ushma), bandage or poultice (bandhana, upanaha) and liquid (drava). Tapa sweating warms the lying patient with heated cloth, palms and the like or with embers; ushma sweating uses heated bricks, stones or coarse grains sprinkled with sour gruel, the patient covered with a wet cloth. A footnote adds steam from a heated pot of milk, curd, sour gruel or vata-reducing decoction.
