Where can we get the heart drug, digitalis?

Explanation:
Digitalis, the heart drug, comes from the foxglove plant. The plant contains cardiac glycosides such as digitoxin and digoxin, which help the heart beat more forcefully and can help regulate rhythm by changing how calcium works in heart cells. This plant-based source is what’s being asked about. Other items don’t provide digitalis: willow is linked to salicylates (the basis of aspirin), coffee beans give caffeine, and plastic isn’t a natural plant source at all.
