Acupuncture originated in China and has been practiced there for thousands of years. Acupuncture treatment improves the body's functions and promotes the natural self-healing process by stimulating specific anatomic sites--commonly referred to as acupuncture points, or acupoints. The most common method used to stimulate acupoints is the insertion of fine, sterile needles into the skin. 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 ointments. Hundreds of clinical studies on the benefits of acupuncture show that it successfully treats conditions ranging from musculoskeletal problems (back pain, neck pain, and others) to nausea, migraine headache, anxiety, depression, insomnia, and infertility. Research suggests that acupuncture could be an effective tool to treat lower back pain. The frequency and number of treatments differ from person to person. Some people experience dramatic relief in the first treatment. For complex or long-standing chronic conditions, one to two treatments per week for several months may be recommended. For acute problems, usually fewer visits are required, usually eight to ten visits in total. The advantage of acupuncture is that it does not have any side effects at all. It is also an affordable treatment.
