Glycyrrhiza is a genus of about 18 accepted species in the legume family (Fabaceae), with a subcosmopolitan distribution in Asia, Australia, Europe, and the Americas.
The genus is best known for liquorice (British English; licorice in American English), G. glabra, a species native to the Mediterranean region, from which the confectionary called Liquorice is produced. Very little G. glabra is grown in North America, but American Licorice G. lepidota is a common native species there. Russian Liquorice (G. echinata) and Chinese Liquorice are also cultivated, the latter being important in traditional Chinese medicine.
Liquorice or licorice is the root of Glycyrrhiza glabra from which a somewhat sweet flavour can be extracted. The compound glycyrrhizic acid, found in liquorice, is now routinely used throughout Japan for the treatment and control of chronic viral hepatitis.
