Quackery is offering medical treatment or advice without qualifications, and is punished severely in most countries. The term evolved from the Middle English word “charlatan,” used to describe people who sold products at fairs. Quackery has been around since the practice of medicine began, but regulation began to emerge in the 19th century. Some famous doctors were accused of being charlatans due to radical ideas. There is dispute about the boundaries of quackery, with some allopathic medicine practitioners viewing alternative and complementary practitioners as charlatans. All forms of healthcare are closely monitored for misleading advertising and claims.
A quack is someone who offers medical treatment or advice without the qualifications to do so. As a general rule, quack is a derogatory term and an accusation of quackery can result in serious punishments, as unlicensed medical practice is punished very severely in most countries. The term “quack” is also used more generally to refer to someone who has no scientific qualifications but still talks about scientific matters.
The word “charlatan” is an abbreviation of “charlatan,” a Middle English word that was used to describe people who sold various groceries and other products at fairs and markets. Typically, quacks would advertise their wares in piercing, loud voices, making a variety of exuberant claims to attract customers, so one can see how the word evolved to refer to an unlicensed practitioner of medicine. “Quacksalver,” incidentally, comes from a Dutch word meaning “to boast.”
Quackery is probably as old as the practice of medicine itself, although it soared to new heights in the 18th and 19th centuries when an explosion of patented drugs plagued many countries in Europe and the United States. Many people saw the potential to make a quick profit and turned to selling patented medicines and dispensing with medical advice as a way to make a living. At the end of the 19th century some attempts at regulation began to emerge and today quackery is treated as a crime, usually prosecuted as a health care fraud.
Some very famous doctors were accused of being charlatans in their day; Louis Pasteur, for example, was mocked and called a quack for proposing that food could be sterilized by the application of heat, although pasteurization is an accepted and widely used practice today. In these cases, the allegations of quackery were the result of radical ideas or an improper understanding of a concept.
There is some dispute about the boundaries of quackery. Some allopathic medicine practitioners, for example, view alternative and complementary practitioners as charlatans, railing against treatments ranging from acupuncture to the use of magnets in medical therapy. Many of these allegations stem from legitimate concerns about the effectiveness of treatments, based on poor performance in empirical tests.
Because of quackery concerns, all forms of healthcare are closely monitored for advertising and claims that could be considered misleading, and only someone with a medical degree is allowed to dispense medical advice, prescriptions, and information. Because of this, many people who practice alternative medicine are severely limited; a massage therapist may work on tight muscles, for example, but cannot legally offer medical advice such as nutritional recommendations to the client.
