Cupping has also been apart of Chinese medicine for over 2,500 years, and is similar to a deep tissue massage. Typically massage oil is applied to the skin, and heat is introduced into the cup. The cup is then applied to the skin. The heat creates a vacuum effect, and skin is drawn up into the cup. This creates an increase of blood to the area, toxin release, increased circulation of the lymph nodes, relaxation of tight muscles, and reduced inflammation. Cupping can leave noticeable marks that resemble a bruise, or a hickey. They may look shocking, but they are not painful. Marks typically disappear within a few days.
