We report the case of a 47-year old woman with a long history of arterial hypertension. Because of a recent difficulty to control blood pressure values accompanied by hypokalaemia, a thorough investigation was performed, showing low renin and aldosterone blood levels and high urinary potassium levels. Repeated questionings revealed that the patient regulary consumed non-negligible quantities of liquorice-flavoured chewing-gum. The physiopathogenic mechanisms of action of liquorice are reviewed.
