High Quality Content by WIKIPEDIA articles! William Withering (17 March 1741 6 October 1799) was an English botanist, geologist, chemist, physician and the discoverer of digitalis. Withering was born in Wellington, Shropshire, trained as a physician and studied at the University of Edinburgh. He worked at Birmingham General Hospital from 1779. The story is that he noticed a person with dropsy (swelling from congestive heart failure) improve remarkably after taking a traditional herbal remedy; Withering became famous for recognising that the active ingredient in the mixture came from the foxglove plant. The active ingredient is now known as digitalis, after the plant's scientific name.
