Subset. Naturopaths incorporate notions from a number of fringe areas including oriental medicine, ayurvedic medicine, acupuncture, moxibustion, chiropractic, and herbal theories. All of these use methods which have not been subject to rigorous clinical testing of the type that is a requirement in standard medical practice.
Little differance. Naturopathic medicine blends centuries-old natural, nontoxic therapies with current advances in the study of health and human systems, covering all aspects of family health from pediatric to geriatric care. In the United States, oriental medicine refers to a graduate-level degree program of acupuncture and chinese herbal medicine, with tuina, qigong and associated modalities. A msom, msaom or mstom.
Proven vs unproven. By definition, "alternative" is different than modern western medicine. Generally any drug, herb, treatment, or procedure that stands up to rigorous scientific scrutiny is included in modern medicine. The problem is that many alternative practices, herbs etc do not stand up to scientific scrutiny and cannot be shown to work. They therefore remain "alternative". Be careful and watch your wallet.
