This ancient Chinese treatment involves glass cups being heated and stuck to the skin, creating a vacuum. The suction cups help draw toxins from the body and increase circulation. The treatment is said to aid asthma, back pain, and blocked colons. It is also known toboost the immune system. Although the procedure looks painful, the temporary red welts are the only cringe-worthy side effect. A big fan of the procedure is Gwyneth Paltrow.
