Acupuncture is a 3000-year-old holistic health practice stemming from Traditional Chinese Medicine. The most common method involves insertion of fine, sterile needles into the skin, stimulating specific anatomic sites and triggering the body's natural self-healing process. Pressure, heat, or electrical stimulation may further enhance the effects. Other acupoint stimulation techniques include: manual massage, moxibustion or heat therapy, cupping, and the application of topical herbal medicines and linaments. In 1997, the U.S. National Institutes of Health (NIH) documented and publicized acupuncture’s safety and efficacy for treating a wide range of conditions. Acupuncture is now covered by many insurance policies and is used most broadly to relieve pain.
