Editing Cinchona (section)

=== Homeopathy ===
The birth of [[homeopathy]] was based on cinchona bark testing. The founder of homeopathy, [[Samuel Hahnemann]], when translating [[William Cullen]]'s ''[[Materia medica]]'', noticed Cullen had written that Peruvian bark was known to cure intermittent fevers.<ref>{{cite book

</ref> Hahnemann took daily a large, rather than homeopathic, dose of Peruvian bark. After two weeks, he said he felt malaria-like symptoms. This idea of "like cures like" was the starting point of his writings on homeopathy. Hahnemann's symptoms have been suggested by researchers, both homeopaths and skeptics, as being an indicator of his hypersensitivity to quinine.<ref>{{cite journal|last=Julian|first=F.
