Cupping is the use of combustion, suction, squeeze and other methods to remove the air in the cupping jar, which results in negative pressure in the cupping jar and makes it attached to the specific parts of the body surface (the affected area or points). This produces a wide range of stimuli from the body which results in disease prevention and treatment or strengthening of the body's physical fitness. This is particular effective for treating anemofrigid cold, joint pain, anemofrigid-damp arthralgia, cough and asthma, skin eczema, and pains in the neck, shoulder, back and other parts of the body.
