Fire cupping is a kind of physical therapy, which can play the role of dispelling wind and removing dampness (dispelling wind and dampness in the body), relaxing tendons and activating collaterals (stretching the tendons and bones, dredging the meridians and channels), and to a certain extent, it can get rid of dampness in the body. In clinical practice, it is mainly used to treat pain caused by blockage of meridians, such as wind-cold-dampness paralysis (paralysis of limbs caused by wind, cold and dampness). Fire Cupping is generally used on the skin surface, mainly through its suction and extraction effect, to promote the flow of blood and qi, and expel dampness. Fire cupping has a good therapeutic effect on dampness caused by external environmental factors such as humidity, but it is usually ineffective in treating dampness caused by internal factors such as spleen deficiency, which needs to be treated with medication under the guidance of a doctor. It is recommended that patients who need to get rid of dampness should go to a regular hospital to identify the cause of the disease, and if fire cupping is needed, it should be operated by a professional doctor to avoid side effects or aggravation of the condition caused by self-operation.
