    Viewers have heard that eating too much black licorice can make you sick.

    As it turns out, some people can overdose on black licorice, according to the Food and Drug Administration.

    Those 40 and older who eat 2 ounces of black licorice a day for two weeks could end up in the hospital with an irregular heartbeat, the FDA said. That’s caused by a sweetening compound that can cause potassium levels in the body to fall.

    Potassium levels usually return to normal when black licorice consumption stops.

    The FDA advises people of all ages shouldn’t eat large amounts of black licorice in one sitting.
