Digitalis purpurea

It is also known as the Common/Purple Foxglove or the Lady's Glove. The flowers are typically purple in colour but they can be pink or even white in some cultivations.

At the end of the 18th century, William Withering introduced digitalis leaves as a tea into the treatment of “cardiac dropsy” (edema of congestive heart failure) and it helped many people. The active principles in these plants are steroids with one or more sugar molecules attached at C3.

Proven clinically, digoxin continues to be obtained from the plants Digitalis purpurea or D. lanata because its chemical synthesis is too difficult and expensive.
