Cupping therapy is the method of using glass 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. The vacuum inside the cups causes the blood to flow in the area and help the healing in that area.
Ancient Chinese medicine maintains that the body contains "Meridians". These meridians are pathways in the body which the energy of life called Qi ("chi") flows through. It flows through every body part, tissue, and organ. Cupping therapy is mainly performed on one's back because there are five meridians on your back. When these meridians are opened, the internal energy is able to flow through the whole body.
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.
Cupping therapy has been found in ancient records dating back 3500 years and it is still used today.
