Ainsworths – formally registered as Ainsworths (London) Ltd – is a British limited company. It describes itself as specializing "in the making and provision of traditional homoeopathic remedies and the individual preparation of Bach flower remedies".
The company's founder, John Ainsworth, had previously been a director of Nelsons, a homeopathic pharmacy. His new company was incorporated in 1974 as J.B.L. Ainsworth (Caterham) Ltd, and its first pharmacy opened in London in 1978. By 1989 the company had 56 employees. In 2009 the company changed to its current name.
Ainsworths is a member of the British Association of Homeopathic Manufacturers.
In 2009 Ainsworths was cleared following an investigation by the Royal Pharmaceutical Society into its sale of homeopathic remedies for Swine flu, on the basis that the products were not sold by an organization registered with them.
In 2013, a BBC News investigation found that Ainsworths was willing to advise parents to use homeopathic pills to as a substitute for immunization against whooping cough. Adam Finn, a pediatrician at the Bristol Royal Infirmary was quoted as saying "I'm very concerned because what I know about vaccines tells me these cannot possibly be effective at preventing infections".
