Cupping therapy is the method of using glass or plastic cups to create localized pressure by a vacuum. The Chinese have been doing this since ancient times by using heat inside glass or bamboo cups. Nowadays, cupping sets use suction to create the vacuum. The vacuum inside the cups causes the blood to form in the area and help the healing in that area.Another healing aspect of cupping therapy is through the release of toxins in your body. The suction from the cups can penetrate deep into your tissues causing the tissues to release harmful toxins. It triggers the lymphatic system, clears the blood vessels, and stretches and activates the skin.
