What are the advantages and disadvantages of drawing fire and filling water?

Cupping has the functions of dredging meridians, promoting qi and blood circulation, relieving swelling and pain, expelling wind and dispelling cold, and has a wide range of treatment. Can be used for treating rheumatic joint pain, nerve paralysis and some acute and chronic pains such as shoulder pain, lumbago, abdominal pain, dysmenorrhea, epigastric pain, dyspepsia, and common cold. In addition, surgical diseases such as ulcers that do not fester at first, erysipelas, etc. can be used.

Its disadvantage is 1. Novices can't master cupping skills well, such as too much alcohol or poor grip, which is easy to burn patients or cause accidents; 2。 Whether it is a bamboo jar or a glass jar, the edge of the jar mouth is overheated, and the operator will burn the patient or even blister if he is not alert. 3。 If the glass jar is chipped, it will scratch the patient. 4。 Disinfection: sometimes after cupping or pricking, the disinfection of cans is not complete. After another patient comes, the same jar is used repeatedly for cupping. If the skin is damaged, it will easily lead to cross infection.
