Cupping is a traditional Chinese medical treatment in which cups are placed on the patient's skin along the meridian lines and a vacuum is created when heat is applied and then the air inside the cup is allowed to cool. " The cupping method has the function of warming and promoting the free flow of qi and blood in the meridians, dispelling cold dampness, diminishing swellings and pains. In clinics, the cupping method is mainly used to treat Bi syndrome caused by wind dampness, such as pain of the low back, shoulders, and leg, gastrointestinal disorders such as stomachache, vomiting, and diarrhea, and the lung disease such as cough and asthma. The cupping method combined with bloodletting is suitable to treat acute sprains accompanied by blood stasis." (1)
