Cupping is a technique that uses a partial vacuum that is created inside thick glass cups by burning all the oxygen that is within the cup. The cup is immediately placed on the skin and the vacuum draws the skin up into the cup. This therapy infuses the tissue with more circulation of Qi, blood and lymph. Most patients feel like it is a soothing deep tissue massage. Cupping is used to reduce muscle spasms and tension, relieve pain, improve asthma and coughs and to hasten the healing of injuries. There can be marks left by cupping but these will fade in several days.
