Just in time for Halloween, the Food and Drug Administration is warning people about eating too much black licorice.
The FDA says the candy contains a substance known as glycyrrhizin that can lead to lower potassium levels in your body, abnormal heart rhythms, high blood pressure, muscle weakness, swelling and even heart failure.
