Zone Therapy can be traced to the Egyptians and is the origin of hand and foot reflexology and also has a relationship to the acupressure circuitry. With Zone Therapy, the body is divided by vertical lines into five zones on the left side and five on the right side that relate to all parts of the body. The fingers and toes affect corresponding parts of the body and are the primary areas of treatment. Zone Therapy works more directly on nerve endings that are connected with organs along the zones and is a very effective technique for pain release.
