A cup is applied to the skin and the pressure in the cup is reduced by using heat or by suctioning out air, so that the skin and superficial muscle layer is drawn into and held in the cup.
Generally, the cup is left in place for about 10 minutes (typical range is 5–15 minutes). The skin becomes reddened due to the congestion of blood flow. The cup is removed by pressing the skin along side it to allow some outside air to leak into it, thus equalizing the pressure and releasing it. Some bruising along the site of the rim of the cup is expected.
Today, cupping is mainly recommended for the treatment of pain, gastro-intestinal disorders, lung diseases (especially chronic cough and asthma), and paralysis, though it can be used for other disorders as well. The areas of the body that are fleshy are preferred sites for cupping
But Cupping is not for everyone. Contraindications for cupping include: areas of skin that are inflamed; cases of high fever, convulsions or cramping, or easy bleeding (i.e., pathological level of low platelets); or the abdominal area or lower back during pregnancy.
