Acupuncture is one of the oldest, most commonly used systems of healing in the world. Originating in China some 4,000 years ago, only in the last three decades has it become popular in the United States.

Traditional Chinese medicine holds that there are as many as 2,000 acupuncture points on the human body, which are connected by 20 pathways (12 main, 8 secondary) called meridians. These meridians conduct energy, or qi (pronounced "chi"), between the surface of the body and its internal organs. Each point has a different effect on the qi that passes through it. Qi is believed to help regulate balance in the body. It is influenced by the opposing forces of yin and yang, which represent positive and negative energy and forces in the universe and human body. Acupuncture is believed to keep the balance between yin and yang, thus allowing for the normal flow of qi throughout the body and restoring health to the mind and body.

In the late 1970s, the World Health Organization recognized the ability of acupuncture and Oriental medicine to treat nearly four dozen common ailments, including neuromusculoskeletal conditions (such as arthritis, neuralgia, insomnia, dizziness, and neck/shoulder pain); emotional and psychological disorders (such as depression and anxiety); circulatory disorders (such as hypertension, angina pectoris, arteriosclerosis and anemia); addictions to alcohol, nicotine and other drugs; respiratory disorders (such as emphysema, sinusitis, allergies and bronchitis); and gastrointestinal conditions (such as food allergies, ulcers, chronic diarrhea, constipation, indigestion, intestinal weakness, anorexia and gastritis).

In 1997, a consensus statement released by the National Institutes of Health found that acupuncture is useful to treat addiction, headaches, menstrual cramps, tennis elbow, fibromyalgia, myofascial pain, osteoarthritis, lower back pain, carpal tunnel syndrome and asthma.
