Types of complementary and alternative medicine
The National Institute of Health's National Center for Complementary and Alternative Medicine (NCCAM) classifies complementary and alternative medicine and therapies according to the following "practices":Manipulative and body-based practices are based on manipulation or movement of one or more body parts. Examples include various types of massage therapy of the soft tissues of the body (various types), chiropractic, Trager bodywork, Rolfing and acupuncture .
Mind-body medicine uses a variety of techniques designed to enhance the mind's ability to affect bodily function and symptoms. Examples include relaxation, biofeedback, yoga , meditation, hypnosis, and tai chi.
Biologically based practices use substances found in nature, such as herbs, special diets, or vitamins (in doses outside those used in conventional medicine). Examples include nutritional supplements like antioxidants, a low-carbohydrate diet like Atkins, or a biological supplement like milk thistle.
Energy medicine involves the use of energy fields, such as magnetic fields or biofields (energy fields that some believe surround and penetrate the human body). Examples include Qi gong, intercessory prayer (prayer on behalf of another), and healing touch (the type that purports to identify imbalances and correct energy by the therapist).
Whole medical systems are built upon complete systems of theory and practice. Often, these systems have evolved apart from and earlier than the conventional medical approach used in the United States. Examples include homeopathy and traditional Chinese medicine.
