Cupping (拔罐) is the treatment of disease by suction of the skin surface. A vacuum is created in glass cups which are then attached to the body surface. The vacuum causes a drawing up of the underlying tissues into the cups, pulling inner congestion of fluids like mucus or blood, moving stagnant energy, and can also reduce swelling.
This practice, when completed correctly, is actually capable of relieving a great deal of discomfort in your body and can activate the lymphatic system, promote blood circulation, expel toxins, and promote deep healing.
More and more athletes like to useing the cupping to improve their performance.
