What Is Traditional Chinese Medicine?
Traditional Chinese medicine (TCM) has evolved over thousands of years. TCM practitioners use various psychological and/or physical approaches (such as acupuncture and tai chi) as well as herbal products to address health problems.
What the Science Says About the Effectiveness of Traditional Chinese Medicine
Acupuncture is a technique in which practitioners stimulate specific points on the body, usually by inserting thin needles through the skin. Studies suggest that acupuncture stimulates the release of the body’s natural painkillers and affects areas in the brain involved in processing pain; however, some trials suggest that real acupuncture and sham acupuncture are equally effective, indicating a placebo effect. Results from a number of studies, however, suggest real acupuncture may help ease types of pain that are often chronic, such as low-back pain, neck pain, osteoarthritis/knee pain, and carpal tunnel syndrome. It also may help reduce the frequency of tension headaches and prevent migraine headaches. For more information, see NCCIH’s acupuncture fact sheet.
Tai chi combines certain postures, gentle movements, mental focus, breathing, and relaxation. Research findings suggest that practicing tai chi may improve balance and stability in older people and those with Parkinson’s disease, reduce pain from knee osteoarthritis, help people cope with fibromyalgia and back pain, and promote quality of life and improve mood in people with heart failure.

Chinese Herbal Products
Chinese herbal products have been studied for many medical problems, including stroke, heart disease, mental disorders, and respiratory diseases (such as bronchitis and the common cold), and a national survey showed that about one in five Americans use them. Because many studies have been of poor quality, no firm conclusions can be made about their effectiveness. For more information about specific herbs, see NCCIH’s
