Licorice-Induced Pseudohyperaldosteronism: A Case Report.

We present a 71-year-old man admitted to the intensive care unit with severe hypokalemia after ingesting licorice-containing confectionary over 6 weeks. Excess consumption of licorice with its active metabolite glycyrrhizic acid may precipitate pseudohyperaldosteronism with life-threatening hypokalemia. Public awareness and measures such as warning labels are needed to warn against excessive consumption.
