Cupping is a form of Traditional Chinese Medicine that involves heating glass or ceramic cups with fire and placing them on specific points on the body to create a local suction to facilitate the movement of blood in order to promote healing. Depending on the condition being treated, the cups are left in place for about 5-10 minutes; moved along the skin with oil; or placed momentarily, then moved to nearby location. Like a massage, moving the cups over the muscles increases blood and lymph circulation.
The cups may leave round red marks on the skin that last for up to one week. Areas that are cupped should be kept covered and protected from cold and wind for about 48 hours.
