alternative medicine, the treatment and prevention of disease by techniques that are regarded by modern Western medicine as scientifically unproven or unorthodox. The term alternative medicine can encompass a wide range of therapies, including chiropractic, homeopathy, naturopathy, acupuncture, herbal medicine, meditation, biofeedback, massage therapy, and various "new age" therapies such as guided imagery and naturopathy. Although many alternative therapies have long been widely employed in the treatment of disease, the scientifically oriented modern medical establishment has typically been skeptical about, and sometimes strongly opposed to, their use. Despite this, Americans spend billions of dollars on alternative treatments each year. In 1993 the U.S. National Institutes of Health established the Office of Alternative Medicine to examine the merits of such techniques. See also holistic medicine.
