An increasing number of health insurance policies provide benefits for so-called alternative medicine—that is, for therapeutic practices and treatments that lie outside the mainstream of Western medical care. Policies that cover alternative medicine may provide benefits for such treatments as acupuncture, chiropractic care, therapeutic massage, and naturopathy (treatments that avoid drugs and surgery in favor of natural remedies). Advocates of alternative medical practices believe that they can provide safe, natural approaches to treating illnesses or injuries that conventional medicine has had limited success in curing, such as chronic pain and drug addiction.
