Digitalis (Foxglove)

Digitalis, commonly known as foxglove, is a plant that contains compounds called digoxin and digitoxin, which influence heart function. These substances help strengthen the heart's contractions and regulate irregular heartbeats, making them useful in treating certain heart conditions. However, digitalis is potent and requires careful medical supervision because an overdose can be toxic. Historically, foxglove was a vital source for these heart medications, and while synthetic versions are now often used, digitalis remains important in cardiology when administered appropriately.
