Cupping is the application of cups to specific points on a person’s body through suction. Cups come in various sizes and materials (glass, plastic, bamboo etc.), and are secured to the skin through a variety of ways (fire, water, or vacuum cupping). The cups are placed on areas of pain, tightness, or dysfunction, and left in place for a given amount of time. The cups may also be moved around while suctioned to the skin, creating a similar effect to skin rolling.
