A traditional Chinese and Middle Eastern treatment for many ailments is cupping therapy. It is positioning cups on a person's skin in specific locations. By applying suction to the cups, a practitioner applies pressure to the skin. You can cup something wet or dry. A little amount of the patient's blood is drawn during the process of wet cupping, which requires puncturing the skin before beginning the suction. After being exposed to the suction effects of cupping, a person's skin usually develops round bruises as blood vessels burst.
