Liquorice can also be used to treat skin inflammation and infections. Research published in 1980 demonstrated the anti-inflammatory effects of glycyrrhizinic acid against erythema (reddening of the skin) caused by exposure to ultraviolet light. Liquorice also stimulates the secretion of aldosterone, a hormone that causes water and sodium retention, but prevents the retention .of potassium. As a result, it has adverse side effects if taken in large doses, particularly in people with heart or liver problems.
