The meridian system is a key concept of traditional Chinese Medicine. It is believed that energy—also called the life force, prana, or qi (chi)—flows throughout the body in the same way that blood does. When this energy becomes blocked or disproportionate, adverse symptoms and disease may occur. Every organ and every part of your body is directly linked to a specific tooth or area of the mouth via these meridians, or energy highways.
