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 , from kwakzalver a "hawker of salve". In the Middle Ages the term quack meant "shouting". The quacksalvers sold their wares at markets by shouting to gain attention.
Common elements of general quackery include questionable diagnoses using questionable diagnostic tests, as well as untested or refuted treatments, especially for serious diseases such as cancer. Quackery is often described as "health fraud" with the salient characteristic of aggressive promotion.
Psychiatrist and author Stephen Barrett of Quackwatch defines quackery as "the promotion of unsubstantiated methods that lack a scientifically plausible rationale" and more broadly as:
"anything involving overpromotion in the field of health." This definition would include questionable ideas as well as questionable products and services, regardless of the sincerity of their promoters. In line with this definition, the word "fraud" would be reserved only for situations in which deliberate deception is involved.
In addition to the ethical problems of promising benefits that are not likely to occur, quackery might cause people to forego treatments that are more likely to help them, in favor of ineffective treatments given by the "quack".
American pediatrician Paul Offit has proposed four ways in which alternative medicine "becomes quackery":
"by recommending against conventional therapies that are helpful."
"by promoting potentially harmful therapies without adequate warning."
"by draining patients' bank accounts ..."
"by promoting magical thinking ...

Vitalism is a belief that starts from the premise that "living organisms are fundamentally different from non-living entities because they contain some non-physical element or are governed by different principles than are inanimate things." Where vitalism explicitly invokes a vital principle, that element is often referred to as the "vital spark", "energy", "élan vital" (coined by vitalist Henri Bergson), "vital force", or "vis vitalis", which some equate with the soul.
