Chronic ingestion of liquorice induces a syndrome with
findings similar to those in primary hyperaldosteronism.
We describe a patient who, with a plasma K<sup>+</sup> of 1.8 mmol/l, showed a paralysis and severe rhabdomyolysis after the habitual consumption of natural liquorice. Liquorice has become widely available as a flavouring agent in foods and drugs. It is important for physicians to keep liquorice consumption in mind as a cause for hypokalaemic paralysis and rhabdomyolysis.
