Complementary and alternative therapies are those not yet considered mainstream and, therefore, not normally offered by conventional medical providers. “Complementary medicine” refers to use of CAM together with conventional medicine, such as using acupuncture in addition to usual care to help lessen pain. Most use of CAM by Americans is complementary.
“Alternative medicine” refers to use of CAM in place of conventional medicine. “Integrative medicine” (also called integrated medicine) refers to a practice that combines both conventional and CAM treatments for which there is evidence of safety and effectiveness. CAM treatments include, but are not limited to: nutrition, herbal medicine, spinal manipulation, “energy medicine,” homeopathy, massage therapy, spiritual attunement, relaxation training and stress management, biofeedback and acupuncture.
The list of what is considered complementary and alternative therapy is constantly changing as more research becomes available. As they demonstrate efficacy and safety, these therapies become part of conventional medicine.
