How are complementary health therapies different from holistic medicine?

Holistic Medicine. "complementary health therapies" may be practiced by non-physicians, and are usually used along with ongoing conventional treatments. "holistic medicine" is practiced by physicians, and is the art and science of healing that addresses the whole person. It integrates conventional and complementary therapies to promote optimal health, and prevent and treat disease.
Good question. Holistic medicine addresses the needs of the whole person whereas "complementary therapies" refer to treatments not usually part of conventional medicine - like acupuncture, chiropractic, massage, nutrition, and guided imagery.
