Licorice candy has glycyrrhizin which increases cortisol (stress hormone) levels in the body. This causes hypokalemia. Hypo- low. Kal- kalium (potassium). emia- presence in blood. Potassium signals muscle relaxation. Low potassium, low relaxation. Heart can't relax, then it stops.

Real licorice candy is not easy to get in the United States. It's not at big chain grocery stores. Most of what you can buy from the big brands is licorice flavored, and won't do this.

These cases are patients who I, or my colleagues have seen. They are de-identified and many instances have been presented in more depth in an academic setting. These videos are not individual medical advice and are for general educational purposes only. I do not give medical advice over the internet.
