Infarto agudo de miocardio e hipopotasemia severa por consumo de regaliz durante el confinamiento por COVID-19

Liquorice is one of the oldest known herbs with medicinal properties and comprises up to 300 active compounds. It has been used for millennia for its digestive, anti-inflammatory and anti-infective properties. However, its possible toxic effects were described only a few years ago and there is growing interest in the side effects associated with chronic consumption. The main active component of liquorice is the prodrug glycyrrhizin and its active metabolite glycyrrhetic acid. It is a rare cause of hypokalaemia due to suppression of the renin-angiotensin-aldosterone axis, causing pseudohyperaldostenonism (PHA). We describe a rare case of secondary acute myocardial infarction in a patient with chronic consumption of liquorice.
