Quackery is the promotion of unproven or fraudulent medical practices. Random House Dictionary describes a "quack" as a "fraudulent or ignorant pretender to medical skill" or "a person who pretends, professionally or publicly, to have skill, knowledge, or qualifications he or she does not possess; a charlatan".
The word "quack" derives from the archaic word "quacksalver", of Dutch origin (spelled kwakzalver in contemporary Dutch), literally meaning "hawker of salve". In the Middle Ages the word quack meant "shouting". The quacksalvers sold their wares on the market shouting in a loud voice.
"Health fraud" is often used as a synonym for quackery, but quackery's salient characteristic is aggressive promotion ("quacks quack!") rather than fraud, greed or misinformation. "Pseudo-medicine" is a term for treatments known to be ineffective, regardless of whether their advocates themselves believe in their effectiveness.

Famous quotes containing the word quackery:
“Consider the deference which is everywhere paid to a doctor’s opinion. Nothing more strikingly betrays the credulity of mankind than medicine. Quackery is a thing universal, and universally successful. In this case it becomes literally true that no imposition is too great for the credulity of men.”
—Henry David Thoreau (1817–1862)
“The church is a sort of hospital for men’s souls, and as full of quackery as the hospital for their bodies. Those who are taken into it live like pensioners in their Retreat or Sailor’s Snug Harbor, where you may see a row of religious cripples sitting outside in sunny weather.”
—Henry David Thoreau (1817–1862)
