Cupping is one of the common Chinese medical methods for treating external wind, which is a more effective method of physical therapy by giving local negative pressure to relieve tendons and channels, invigorate blood circulation, dispel wind and cold, and relieve swelling and pain. After cupping, there will be red or dark red cupping marks, while the back of the patient shows a blackish purple color is also normal, indicating that there is a disease in the patient’s body, and cupping has an effect on the disease. In Chinese medicine, the presence of black purple color after cupping is considered to be a symptom of “cold paralysis, pain paralysis”, which means that the patient’s body may be invaded by external wind and cold, resulting in obvious pain, numbness, restricted movement, soreness and swelling in the joints, muscles, tendons and other parts of the body. Usually, the black-purple color of the back can gradually subside after a few days, after which the color that appears from cupping will gradually fade and gradually appear red or dark red, indicating that wind-cold is gradually being eliminated and the body is gradually returning to normal. These diseases are similar to rheumatism, rheumatoid arthritis, osteoarthritis, gout, and ankylosing spondylitis in Western medicine, and are usually treated with acupuncture, moxibustion, and topical Chinese herbal medicine in addition to cupping. In addition, after cupping, attention should be paid to local skin protection, avoiding bathing, wind and cold for 24 hours to avoid aggravating the original disease. In addition, it is necessary to keep the local area clean and dry to avoid secondary injury and infection. The diet should be light and avoid spicy and stimulating foods to avoid aggravating the discomfort after cupping.
