Quacks or charlatans refer to people who sell “medical methods that do not work and are only intended to make money”. In Europe in the 15th century it was also common to see long-distance peddlers, who sold supposedly magical healing potions and elixirs. During the Great Plague of London in the 17th century, quacks sold many fake potions promising either cures or immunity. Because pills looked less trustworthy to the public, potions were often the top sellers of quacks. These potions often included bizarre ingredients such as floral pomanders and the smoke of fragrant woods. The well known Wessex quack Vilbert was known to sell love potions made of pigeon hearts.  By the 18th century in England, it was common for middle class households to stock potions that claimed to solve a variety of ailments. Quackery grew to its height in the 19th century.
