Quackwatch

Quackwatch is a United States-based network of people founded by Stephen Barrett, which aims to "combat health-related frauds, myths, fads, fallacies, and misconduct" and to focus on "quackery-related information that is difficult or impossible to get elsewhere." Since 1996 it has operated the alternative medicine watchdog website quackwatch.org, which advises the public on unproven or ineffective alternative medicine remedies. The site contains articles and other information criticizing many forms of alternative medicine.

Quackwatch cites peer-reviewed journal articles and has received several awards. The site has been developed with the assistance from a worldwide network of volunteers and expert advisors. It has received positive recognition and recommendations from mainstream organizations and sources. It has been recognized in the media, which cite quackwatch.org as a practical source for online consumer information. The success of Quackwatch has generated the creation of additional affiliated websites; as of 2013 there were 21 of them. The organization has often been challenged by supporters and practitioners of the various forms of alternative medicine that are criticized on the website.
