But like homeopathy, naturopathy's roots also lie in the reaction by some physicians of 19th Century reaction against the bleedings and purgings of prescientific medicine. In this country, Benedict Lusk is credited as the father of naturopathy. A German physician who immigrated to the U.S. in 1892, Lusk was a believer in the therapeutic powers of water. Adherents of hydropathy, as it was known, made use of water almost as if it were a sacrament in soaks, showers, and the like. They often also advised other measures such "air baths," exercise, and dietary practices as a means to good health. Lusk opened his own water-cure facility in New York City and by 1902 was operating a school of massage, chiropractic, and naturopathy. In 1919 he founded the American Naturopathic Association. With the coming of age of scientific medicine, and especially the introduction of effective antibiotic agents, naturopathy, as well as its other prescientific competitors, receded. But today, with the renewed interest in healthy living, the preoccupation of many with ideas about the effect of spirituality on health, and a lack of understanding and suspicion of science, naturopathy has found fertile ground for a comeback. An N.D. (Doctor of Naturopathy) degree can be had today as a mail-order item. But there also exist two 4-year Naturopathic Schools. In an effort to earn some respectability, these institutions try to emulate to some extent the course of studies offered at reputable medical schools. These are the National College of Naturopathic Medicine in Portland, Oregon, and the John Bastyr College of Naturopathic Medicine in Seattle, Washington. Eight states now permit naturopaths to practice medicine legally: Washington, Oregon, Arizona, Connecticut, Hawaii, Utah, Florida and Alaska. The last three require previous licensure in another state, however. There are said to be some 800 N.D.s doing business in the U.S. currently, a little more than half in Washington and Oregon. Unfortunately, despite their emphasis on good health habits and preventive measures, naturopaths often are at odds with such practices. Because of their emphasis on "natural" healing methods, for example, they may oppose such public health measures as water supply fluoridation and the vaccination of children. Their knowledge of nutrition is, more often than not, nutrition pseudoscience, according to William Jarvis, Ph.D., a professor of health education at Loma Linda University and the President of the National Council Against Health Fraud. Naturopaths denigrate the use of medication by practitioners of medical science, preferring instead to use herbal remedies of various kinds. N.D. Joe Pizzorno, president of the John Bastyr school, for example, says that strep throat is caused by a breakdown of the body's defenses since "if you do routine cultures of the population, 90% have strep in their throat, but it doesn't cause infection" (Medical Tribune, 10/13/88). He therefore treats strep throat with Vitamin C and the herb goldenseal, because berberine, an alkaloid found in the herb, is purported to kill strep. Such claims and practices are simply false, and can be exceedingly dangerous since untreated strep infections can cause heart and kidney damage. Parallel situations exist with respect to asymptomatic gonorrhea, syphilis, and even HIV (the virus which causes AIDS) infection. A naturopath would presumably be uninterested in the presence of these pathogens, whether eradicable by such simple measures as penicillin or not. Naturopaths claim that herbal products are better because they're found in nature, whereas synthetic materials are "chemicals the body's never been exposed to before," and so are more dangerous according to Pizzorno. This assumes that every plant product on the planet was in the immediate environment of our African primate ancestors, of course. It's also a bit like saying that we should be restricting our building materials to grass, mud, and rocks since steel, glass and concrete weren't present during the course of human evolution. William Bennett, M.D., a Cambridge, MA internist and editor of the Harvard Medical School Health Letter, puts it this way: "regarding herbs ... as somehow different from drugs strikes me as just nonsense. Either the herb has no effect, in which case why bother, or it has an effect, in which case it's a drug." Naturopaths claim that purifying a drug from a plant material makes it more toxic, which is why they prefer to use the whole herb in their treatments. Bennett says: "That's a piece of 19th Century romantic philosophy." The fact is that purification of something like digoxin from the foxglove plant makes dosages safer and more standardized. Purification also removes the therapeutically inert materials which can nonetheless have toxic effects of their own. Naturopath Pizzorno also claims that "many of the herbs have synergistic agents that work together to produce the effect you're looking for." But the fact is that no one has identified such "synergistic agents." Despite their antipathy to drugs, naturopaths have fought for and won the right to prescribe in the states of Washington and Oregon. Some also practice obstetrics and perform minor surgery. And while they claim to be an "alternative" to high-priced conventional medicine, they have also actively pursued the right to bill insurance companies and other third-party payers for their services. It's also difficult to see just what the significance of naturopathy's efforts to appear more mainstream really amount to in practical terms. For other than their general preference for "natural" methods, N.D.s may make use of just about any "alternative" medical approaches. These include colored light therapy, homeopathy, iridology, "zone pressure" (pressing with a finger, hand, or toe near the area of concern), acupuncture, massage therapy, and colonic irrigation (enema therapy). If the 4-year colleges teach any science, it doesn't seem to have an effect. Many naturopaths are little more than jacks of all quackeries. In defense of naturopathy, proponents point to their frequent "success" in handling minor illnesses, infections that are less than life-threatening, and chronic medical problems for which medical science can offer no cures either. Undoubtedly, lavishing attention and "natural healing" therapies of some kind on people suffering from disorders with a psychosomatic component is likely to benefit some of them. But it's hardly an honest business to mislead people in this way, or for those interested in alleviating disease to delude themselves into believing in pseudoscience as a means of accounting for their successes. It probably happens frequently that practitioners of medical science attribute a success to their methods of treatment that would have occurred without them. But at least the methods themselves are to a greater or lesser degree connected with a body of facts and reasoning that support them. The ideas and practices of naturopaths are not, which makes them a threat to the unwary public. This information is provided by the D/FW Council Against Health Fraud.
