Clinical trials of PC-SPES appeared to show it had some effect on human hormones, but it was discovered the PC-SPES had been adulterated with estrogenic chemicals, which were likely the cause of these effects. [3]

Alternative medicine is any practice that aims to achieve the healing effects of medicine despite lacking biological plausibility, testability, repeatability or evidence of effectiveness. Unlike modern medicine, which employs the scientific method to test plausible therapies by way of responsible and ethical clinical trials, producing repeatable evidence of either effect or of no effect, alternative therapies reside outside of mainstream medicine and do not originate from using the scientific method, but instead rely on testimonials, anecdotes, religion, tradition, superstition, belief in supernatural "energies", pseudoscience, errors in reasoning, propaganda, fraud, or other unscientific sources. Frequently used terms for relevant practices are New Age medicine, pseudo-medicine, unorthodox medicine, holistic medicine, fringe medicine, and unconventional medicine, with little distinction from quackery.

Magnetic therapy is a pseudoscientific alternative medicine practice involving the weak static magnetic field produced by a permanent magnet which is placed on the body. It is similar to the alternative medicine practice of electromagnetic therapy, which uses a magnetic field generated by an electrically powered device. Magnet therapy products may include wristbands, jewelry, blankets, and wraps that have magnets incorporated into them.

Rolfing is a form of alternative medicine originally developed by Ida Rolf (1896–1979) as Structural Integration. Rolfing is marketed with unproven claims of various health benefits. It is based on Rolf's ideas about how the human body's "energy field" can benefit when aligned with the Earth's gravitational field.

Orthomolecular medicine is a form of alternative medicine that aims to maintain human health through nutritional supplementation. The concept builds on the idea of an optimal nutritional environment in the body and suggests that diseases reflect deficiencies in this environment. Treatment for disease, according to this view, involves attempts to correct "imbalances or deficiencies based on individual biochemistry" by use of substances such as vitamins, minerals, amino acids, trace elements and fatty acids. The notions behind orthomolecular medicine are not supported by sound medical evidence, and the therapy is not effective for chronic disease prevention; even the validity of calling the orthomolecular approach a form of medicine has been questioned since the 1970s.

The National Center for Complementary and Integrative Health (NCCIH) is a United States government agency which explores complementary and alternative medicine (CAM). It was initially created in 1991 as the Office of Alternative Medicine (OAM), and renamed the National Center for Complementary and Alternative Medicine (NCCAM) before receiving its current name in 2014. NCCIH is one of the 27 institutes and centers that make up the National Institutes of Health (NIH) within the United States Department of Health and Human Services.

<span class="mw-page-title-main">Craniosacral therapy</span> Pseudoscientific alternative medicine technique

Craniosacral therapy (CST) or cranial osteopathy is a form of alternative medicine that uses gentle touch to feel non-existent rhythmic movements of the skull's bones and supposedly adjust the immovable joints of the skull to achieve a therapeutic result. CST is a pseudoscience and its practice has been characterized as quackery. It is based on fundamental misconceptions about the anatomy and physiology of the human skull and is promoted as a cure-all for a variety of health conditions.

The Burzynski Clinic is a clinic selling an unproven cancer treatment, which has been characterized as harmful quackery. It was founded in 1976 and is located in Houston, Texas, in the United States. It offers a form of chemotherapy originally called "antineoplaston therapy" devised by the clinic's founder Stanislaw Burzynski in the 1970s. Antineoplaston is Burzynski's term for a group of urine-derived peptides, peptide derivatives, and mixtures. There is no accepted scientific evidence of benefit from antineoplaston combinations for various diseases, and the Clinic's claimed successes have not been replicated by independent researchers. The therapy has been rebranded in various ways over the years to mirror fashions in medicine, for example as a kind of "immunotherapy". The therapy is administered through the ruse of running a large numbers of clinical trials, which long-time Burzynski lawyer Richard Jaffe has described as "a joke".

Hoxsey Therapy or Hoxsey Method is an alternative medical treatment promoted as a cure for cancer. The treatment consists of a caustic herbal paste for external cancers or a herbal mixture for "internal" cancers, combined with laxatives, douches, vitamin supplements, and dietary changes. Reviews by major medical bodies, including the U.S. Food and Drug Administration (FDA), the National Cancer Institute, the American Cancer Society, M. D. Anderson Cancer Center, and Memorial Sloan-Kettering Cancer Center, have found no evidence that Hoxsey Therapy is an effective treatment for cancer. The sale or marketing of the Hoxsey Method was banned in the United States by the FDA on September 21, 1960 as a "worthless and discredited" remedy and a form of quackery.

Alternative cancer treatment describes any cancer treatment or practice that is not part of the conventional standard of cancer care. These include special diets and exercises, chemicals, herbs, devices, and manual procedures. Most alternative cancer treatments do not have high-quality evidence supporting their use and many have been described as fundamentally pseudoscientific.
