Cupping is an ancient technique of alternative medicine where glass cups are put on the body using a flame to create suction. The vacuum formed draws up stagnant blood to the surface of the skin. This creates space for increased circulation, oxygen, living cells and nutrients in the body. This can help alleviate pain and muscle tightness, as well as be a great form of fascial work.
Where there is dead, static blood, lymph, cellular debris, pathogenic factors, and toxins present in the body, Cupping can leave red or purple marks which indicates that the stagnation or disease has been moved from the deeper tissue layers to the surface.
