Complementary and alternative medicine
Alternative medicine is a catch-all phrase used in a variety of ways that can encompass a broad variety of concerns. It might be used, on the one hand, for any set of health, medical or therapeutic practices not blessed by the medical establishment and thus not covered by medical insurance. It might also refer, used by a different person, to practices believed by the established medical authority to be dangerous, deceptive or ineffective. It might even refer to matters on which the established medical authority has no opinion, either because no studies have been done or no opinion sought. Public debates include extreme viewpoints in conflicting directions, from on the one hand, banning anything and everything not blessed by the establishment, and on the other hand, to providing individual freedom to try a wide variety of therapies as long as they are not actually banned as dangerous or illegal and as long as no patently unprovable claims of efficacy are being made to potential clients.
This begs the question: who gets to decide? The U. S. Food and Drug Administration is supposed to prevent companies or individuals from marketing drugs or food which are not known to be safe, and also to prevent anyone from making claims of efficacy which are not supported by independent studies using accepted scientific methodology.
But many state agencies also become involved in regulating what is allowed or not allowed. For example, while medical insurance may not recommend or pay for therapeutic massage, chiropractic manipulation, or acupuncture (just for example), many states require practitioners of these arts to be licensed by a state agency intended to guarantee a certain minimum level of competence and training.
The history of struggles and disputes over medical and health approaches is better told in articles related to a specific unofficial health approach. It is easy to consult a regulating authority to find out what therapies and approaches are "official" (and by definition, everything else may be considered "alternative"). But the issue of whether a specific therapy is "complementary", "harmful", "useful", or whatever, is open to much and passionate dispute.
