Foxglove is a tall plant with beautiful bell-shaped flowers that can be purple, pink, white, or yellow. It is often grown in gardens because of how striking it looks. Behind its beauty, however, foxglove is one of the most important plants in the history of medicine.
In the late 1700s, doctors began noticing something unusual.
A British doctor named William Withering observed that people with severe swelling and weak hearts sometimes improved after taking a traditional herbal mixture that contained foxglove.
Over time, foxglove became known for helping with:
β’ Swelling caused by heart problems
β’ Shortness of breath
β’ Weak or failing hearts
β’ Irregular heartbeats
These early observations eventually led scientists to study the plant in detail and discover exactly how it worked.

π The leaves
Foxglove leaves contain very strong natural chemicals called cardiac glycosides. These compounds have a direct and powerful effect on the heart.
Because foxglove is so strong, it is not safe to use as a home remedy.
Instead, scientists turned the plant into carefully measured prescription medicines.
Foxglove affects the body mainly through the heart.
