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.
Homeopathy or homoeopathy is a pseudoscientific system of alternative medicine. It was conceived in 1796 by the German physician Samuel Hahnemann. Its practitioners, called homeopaths or homeopathic physicians, believe that a substance that causes symptoms of a disease in healthy people can cure similar symptoms in sick people; this doctrine is called similia similibus curentur, or "like cures like". Homeopathic preparations are termed remedies and are made using homeopathic dilution. In this process, the selected substance is repeatedly diluted until the final product is chemically indistinguishable from the diluent. Often not even a single molecule of the original substance can be expected to remain in the product. Between each dilution homeopaths may hit and/or shake the product, claiming this makes the diluent "remember" the original substance after its removal. Practitioners claim that such preparations, upon oral intake, can treat or cure disease.
Pseudoscience consists of statements, beliefs, or practices that claim to be both scientific and factual but are incompatible with the scientific method. Pseudoscience is often characterized by contradictory, exaggerated or unfalsifiable claims; reliance on confirmation bias rather than rigorous attempts at refutation; lack of openness to evaluation by other experts; absence of systematic practices when developing hypotheses; and continued adherence long after the pseudoscientific hypotheses have been experimentally discredited. It is not the same as junk science.
A placebo is a substance or treatment which is designed to have no therapeutic value. Common placebos include inert tablets, inert injections, sham surgery, and other procedures.
Quackery, often synonymous with health fraud, is the promotion of fraudulent or ignorant medical practices. A quack is a "fraudulent or ignorant pretender to medical skill" or "a person who pretends, professionally or publicly, to have skill, knowledge, qualification or credentials they do not possess; a charlatan or snake oil salesman". The term quack is a clipped form of the archaic term quacksalver, derived from Dutch: kwakzalver a "hawker of salve" or rather somebody who boasted about their salves, more commonly known as ointments. In the Middle Ages the term quack meant "shouting". The quacksalvers sold their wares at markets by shouting to gain attention.
Voodoo Science: The Road from Foolishness to Fraud is a book published in 2000 by physics professor Robert L. Park, critical of research that falls short of adhering to the scientific method. Other people have used the term "voodoo science", but amongst academics it is most closely associated with Park. Park offers no explanation as to why he appropriated the word voodoo to describe the four categories detailed below. The book is critical of, among other things, homeopathy, cold fusion and the International Space Station.
Matthias Rath is a doctor, businessman, and vitamin salesman. He earned his medical degree in Germany. Rath claims that a program of nutritional supplements, including formulations that he sells, can treat or cure diabetes, cardiovascular disease, cancer, and HIV/AIDS. These claims are not supported by any reliable medical research. Rath runs the Dr. Rath Health Foundation, has been closely associated with Health Now, Inc., and founded the Dr. Rath Research Institute.

Patrick Holford is a British author and entrepreneur who endorses a range of vitamin tablets. As an advocate of alternative nutrition and diet methods, he appears regularly on television and radio in the UK and abroad. He has 36 books in print in 29 languages. His business career promotes a wide variety of alternative medical approaches such as orthomolecular medicine, many of which are considered pseudoscientific by mainstream science and medicine.
Energy medicine is a branch of alternative medicine based on a pseudo-scientific belief that healers can channel "healing energy" into patients and effect positive results. The field is defined by shared beliefs and practices relating to mysticism and esotericism in the wider alternative medicine sphere rather than any sort of unified terminology, leading to terms such as energy healing, vibrational medicine, and similar terms being used synonymously. In most cases, no empirically measurable "energy" is involved: the term refers instead to so-called subtle energy. Practitioners may classify their practice as hands-on, hands-off, or distant wherein the patient and healer are in different locations. Many approaches to energy healing exist: for example, “biofield energy healing”, “spiritual healing”, “contact healing”, “distant healing”, therapeutic touch, Reiki, and Qigong.

Detoxification foot baths, also known as foot detox, ionic cleansing, ionic foot bath and aqua/water detox are pseudoscientific alternative medical devices marketed as being able to remove toxins from the human body. They work by providing an electric current to an electrode array immersed in a salt water solution. When switched on, the electrodes rapidly rust in a chemical process called electrolysis which quickly turns the water brown. This reaction happens regardless of whether or not a person's feet are immersed in the water and no toxins from the human body have ever been detected in the water after use.
The infinitesimally low concentration of homeopathic preparations, which often lack even a single molecule of the diluted substance, has been the basis of questions about the effects of the preparations since the 19th century. Modern advocates of homeopathy have proposed a concept of "water memory", according to which water "remembers" the substances mixed in it, and transmits the effect of those substances when consumed. This concept is inconsistent with the current understanding of matter, and water memory has never been demonstrated to exist, in terms of any detectable effect, biological or otherwise.
