Traditional Chinese medicine is a branch of traditional medicine that is said to be based on more than 3,500 years of Chinese medical practice that includes various forms of herbal medicine, acupuncture, cupping therapy, gua sha, massage, bonesetter, exercise, and dietary therapy. Acupuncture is a component of TCM commonly found in Western medicine and has received the most study of all the alternative therapies. Some herbal treatments used in TCM can act as medicines and be very effective but may also have serious side effects. In 2004, for example, the FDA banned the sale of dietary supplements containing ephedra and plants containing ephedra group alkaloids due to complications, such as heart attack and stroke. Ephedra is a Chinese herb used in dietary supplements for weight loss and performance enhancement. However, the ban does not apply to certain herbal products prepared under TCM guidelines intended only for short-term use rather than long-term dosing. It also does not apply to OTC and prescription drugs or to herbal teas. TCM should not be used as a replacement for conventional or allopathic treatment, especially for serious conditions, but it may be beneficial when used as complementary therapy. Since some TCM herbal medicines can interfere or be toxic when combined with Western medicines, you should inform your doctor if you are using TCM.
