An 84-year-old man with long-standing hypertension presented to a Canadian ED with a hypertensive emergency, unaware that the cause was licorice tea.

His blood pressure was 196/66mmHg; on physical examination he had signs of volume overload, including pulmonary crackles on auscultation and pitting oedema up to his knees.
