William Withering (17 March 1741 – 6 October 1799) was an English physician, botanist, chemist, and geologist. He is best known for his pioneering work in the medical use of the foxglove plant, from which the cardiac glycoside digitalis is derived.

Early Life and Education

William Withering was born in Wellington, Shropshire, England. He was educated at Edinburgh Medical School, where he graduated with an MD in 1766. His early interest in botany and natural history was evident during his studies, and he became a member of the Linnean Society of London.

Medical Career

Withering began his medical practice in Stafford, but later moved to Birmingham in 1775. He became a physician at the Birmingham General Hospital, where he conducted much of his research. Withering's most significant contribution to medicine was his systematic study of the foxglove plant, which led to the development of digitalis as a treatment for heart disease.

Discovery of Digitalis

In 1775, Withering was introduced to a traditional herbal remedy used by an old woman in Shropshire to treat "dropsy" (now known as edema). The remedy contained over 20 different herbs, but Withering identified the active ingredient as the foxglove plant, Digitalis purpurea. He conducted extensive clinical trials and published his findings in 1785 in the book An Account of the Foxglove and some of its Medical Uses. This work laid the foundation for the modern use of digitalis in treating congestive heart failure and other heart conditions.

Contributions to Botany and Geology

Withering was also a noted botanist and geologist. He published A Botanical Arrangement of All the Vegetables Naturally Growing in Great Britain in 1776, which was one of the first comprehensive floras of the British Isles. He was a member of the Lunar Society of Birmingham, a group of prominent scientists, inventors, and industrialists, which included Erasmus Darwin, James Watt, and Matthew Boulton.

Personal Life and Legacy

William Withering married Helena Cookes in 1772, and they had three children. He continued his medical practice and research until his death in 1799. Withering's work on digitalis remains a cornerstone of cardiology, and his contributions to botany and geology are also well-regarded.
