Cupping therapy was also practiced in ancient Greece and Rome. Cupping therapy causes negative pressure inside the can through exhaust, the edge of the can is tightly attached to the skin surface, pulling the nerves, muscles, blood vessels and subcutaneous glands, which can cause a series of neuroendocrine reactions, regulate the vascular diastolic, contractile function and vascular permeability to improve local blood circulation.
