FDA: Eating too much black licorice is harmful

The FDA is warning consumers that the main sweetener in the licorice root, a compound called Glycyrrhizin, can cause drops in potassium levels. That can lead to abnormal heart rhythms, high blood pressure, and even a heart attack.

The FDA is also suggesting that anyone taking prescription drugs consult with their doctor or druggist before dipping into the black licorice stash.
