The key principle that defines and connects all of Chinese medicine is that of Chi, or vital energy. The chi of all organs must be in balance, neither too active nor too dormant, for a person to be healthy. The chi of the body’s organs and systems are all connected in meridians or channels that lie just under the skin. A naturopathic doctor will use Eastern herbs and acupuncture to assist the body in regulating the chi and achieving balance. Acupuncture is the use of very thin needles which are inserted into specific meridian points on the body. The practice of acupuncture has been used for over two-thousand years and has proven to be very effective especially for pain relief and chronic illness.
