Foxglove (Digitalis purpurea)
Cheshire, England, 2004

In 1785 William Withering, working as a doctor in Birmingham, published "An account of the foxglove and some of its medical uses: with practical remarks on dropsy and other diseases."

Dr. Withering wasn't the first to discover that foxgloves could be used to treat some forms of heart failure, but his methodical observations and clinical trials, and his identification of the drug digitalis, marked a major advance in medical practice.
