Cupping helps to increase circulation to an affected area. It is useful as a pain-relieving tool, as well as to enhance immune function and to promote detoxification. Cupping involves the use of glass cups in which the oxygen is removed by fire. It is then placed on the skin to create a vacuum, drawing up the skin and muscular tissue and breaking the tiny capillaries at the surface of skin. This action promotes the regeneration of new blood vessels, helps the body to rid toxins, reduces muscular tension and even diminishes cellulite. Although one should expect bruising for a few days after receiving cupping, this treatment is safe and yields significant results. People often compare the sensation of cupping to a massage.
