Cupping should be done with 95-degree alcohol, because the higher the alcohol content, the greater the negative pressure, and the more effective the cupping is. The main purpose of cupping is to adjust the function of the body and prevent and control diseases by using the cans, which are burned by fire to create a certain negative pressure inside the cans, so that the cans are adsorbed on the selected acupoints. Generally cupping alcohol concentration need to choose 95 degrees, due to 95 degrees of alcohol compared to 75 degrees of alcohol, the concentration is higher, when the flame generated in the combustion is larger, it is easier to form a larger negative pressure in the can, so that the can is firmly adsorbed on the surface of the body. However, it should be noted that there are certain contraindications to cupping therapy, for acute serious diseases, contact with infectious diseases, serious heart disease, heart failure and other conditions of patients, need to be contraindicated to take cupping therapy. During the cupping period, if the patient is not feeling well, he should report to the doctor in time.
