Glycyrrhizin is the glycoside found in licorice root that is responsible for licorice’s unique flavor. It is extremely sweet but its distinctive taste makes it unsuited to use as a sweetener. It is used as a flavoring agent.
Excess glycyrrhizin intake can cause hypertension, water retention, and can interfere with kidney function and metabolism of certain hormones.
The EU recommends limiting consumption to no more than 100mg a day.
