History of Licorice
Licorice (Glycyrrhiza glabra) is a wild plant from the Fabaceae family, native to Southern Europe, Northern Africa, and temperate regions of Asia
The leaves are compound, consisting of 4 to 7 pairs and a terminal leaflet, and are sticky due to resin secretion. The plant has bluish flowers and produces pods containing 5 to 6 brownish seeds.

Licorice, also known as "sweet root," is much sweeter than sugar. It has been used for thousands of years in traditional Chinese medicine and is considered a “harmonizer.” Today, it is widely used and cultivated across Russia, Spain, France, the UK, Germany, the Middle East, and Asia.
