Acupuncture The NCAHF asserted that
acupuncture is scientifically unproven as a modality of treatment. In 1990, it said that research during the past twenty years had failed to demonstrate that acupuncture was effective against any disease. Perceived effects of acupuncture are, argued the NCAHF, probably due to a combination of expectation, suggestion and other psychological mechanisms. The NCAHF pointed out that acupuncture was banned in China in 1929 but underwent a resurgence in the 1960s. The organization also advocated that insurance companies should not be required to cover acupuncture treatment and that licensure of lay acupuncturists should be phased out.
Amalgam fillings There has been some controversy regarding the use of
amalgam fillings by dentists, because the amalgam contains mercury. Some forms of
mercury are toxic to humans, but the NCAHF cites the CDC in stating that there is no evidence that "the health of the vast majority of people with amalgam is compromised" or that "removing amalgam fillings has a beneficial effect on health". The NCAHF criticizes those who they believe exploit unfounded public fears for financial gain. NCAHF asserts that breath, urine and blood testing for mercury are inaccurate. Other tests for mercury exposure described by the NCAHF as invalid can include skin testing, stool testing,
hair analysis and electrodermal testing.
Chiropractic The NCAHF contended that
chiropractic can be dangerous and lead to injury or permanent disability. However, the NCAHF did not categorically oppose the practice. It differentiated between chiropractors who promote what it considered good and bad chiropractic practices. The former promote methods of diagnosis and treatment which have a scientific basis. For example, NCAHF claims there is no scientific support for
vertebral subluxation. Unverified assessment methods such as
iridology,
applied kinesiology, and routine
hair analysis for assessment of nutritional status are criticized. NCAHF and some of its members have long opposed implementation of beliefs that they characterize as unfounded or unscientific. NCAHF also questioned the health claims, marketing, safety, efficacy and labeling of many
herbal supplements. Herbal preparations are regulated as foods, rather than as drugs, in the United States. The NCAHF advocates regulations for a special
OTC category called "Traditional Herbal Remedies" (THRs) with an adverse reaction surveillance program, product batches marked for identification and tracking, package label warnings about proposed dangers of self-treatment, oversight requirements from outside of the herbal industry, and strong penalties for unapproved changes in herbal product formulations.
Diploma mills The NCAHF asserted that many unqualified practitioners are able to mislead the public by using
diploma mills or "degree mills" to get "specious degrees". Diploma mills are not accredited, and frequently engage in "
pseudoscience and
food faddism". NCAHF also noted that "some of the 'faculty' or 'academic' advisors at several of these schools have criminal convictions in the area of health fraud". NCAHF considers diploma mills harmful to the students and to the public. == Usefulness as a source ==
