Torsade de Pointes Caused by a Compound Licorice Tablet

The clinical manifestations of licorice-induced pseudoaldosteronism include muscle weakness, periodic paralysis, hypokalemia, and hypertension. Excessive licorice consumption can lead to adverse reactions affecting multiple systems, including the endocrine, cardiovascular, nervous, digestive, and immune systems. Although licorice is a frequently used Chinese herbal medicine, life-threatening adverse reactions have been reported among its users. This article presents a case of severe hypokalemia, torsade de pointes, severe hypertension, and exacerbation of manic symptoms resulting from an overdose of compound licorice tablets. This study aimed to enhance the understanding of the causes of hypokalemia and raise awareness on the potentially fatal adverse reactions associated with licorice drugs.
