What does quackery mean?
Quackery names deceptive practices or claims that are presented as knowledgeable, authoritative, or therapeutic despite lacking reliable evidence. Its most common use is in medicine and health care, where unsupported remedies, miracle cures, and false medical advice can cause people to delay effective treatment. The word is strongly critical: it implies deliberate misrepresentation, exploitation, or credulity rather than merely a mistaken belief. Quackery can also describe broader forms of bogus expertise, commercial deception, and pseudoscientific promotion. For example, a website selling an unproven supplement with dramatic claims of curing disease would be promoting quackery. Although closely related to the word quack, which names the person responsible, quackery focuses on the practices, claims, and resulting culture of deception.
nounQuackery is the practice of promoting or using dubious medical theories, remedies, or treatments without reliable scientific evidence. It can also refer more broadly to unfounded claims or deceptive practices presented as authoritative or beneficial.
- The use or promotion of dubious medical treatments, remedies, or theories, especially when presented as legitimate medical knowledge.
"The campaign aimed to expose the quackery behind several popular but medically unproven remedies."

"Public-health campaigns are often designed to warn consumers about quackery and fraudulent health products."
The plural is used when referring to multiple instances or forms of deceptive, unsupported practice.

Quackery sounds harmless like a duck, but its consequences can be serious: persuasive health claims can lead people away from effective treatment.

Where does quackery come from?
Quackery is formed from quack, meaning a person who dishonestly claims medical knowledge, together with the suffix -ery, which forms nouns denoting an activity, practice, or collection. The word quack developed in the 17th century and was influenced by the earlier word for a duck's call, with the sense of noisy, boastful, or dubious talk. Its medical sense became established through association with unqualified practitioners and fraudulent remedies.
How quackery is actually used
