FDA Warns Against Too Much Black Licorice
For adults age 40 or older, the FDA says, eating 2 ounces of black licorice a day for at least two weeks may lead to arrhythmia, or irregular heart rhythm, which could land you in the emergency room.
The culprit is glycyrrhizin, a sweetening compound derived from licorice root. In large amounts, glycyrrhizin can cause the body’s potassium levels to drop, which in turn, may lead to abnormal heartbeat and high blood pressure. It can also cause water retention and swelling, which is a particular risk for people with congestive heart failure.
