What diseases does foxglove treat?

Heart failure: Foxglove (Digitalis) is primarily used to treat congestive heart failure, a condition in which the heart is unable to pump blood effectively. It helps the heart work more efficiently by increasing the force of its contractions and slowing down the heart rate.

Atrial fibrillation: Foxglove can also be used to control the heart rate in people with atrial fibrillation, a type of irregular heartbeat that originates in the heart's upper chambers.

Other uses: Foxglove has also been used historically to treat various cardiac conditions such as atrial flutter, paroxysmal tachycardia, and heart valve disease, but its use in these indications is limited due to the availability of safer and more effective alternatives.
