A sticky, perennial herb with underground stems (rhizomes). The hairy stems are upright, growing to about 1 m tall
Leaves divided into 9–17 leaflets, held on a leaf stalk 10–20 cm long. The leaflets are arranged in pairs along a central axis, with a single leaflet pointing outwards at the end.
Flowers light blue to violet (rarely white), 1.0–1.5 cm long and resembling sweet pea flowers in shape. The flowers are held in loose, conical spires, almost as long as the leaves, each consisting of 10 or more individual flowers.
Plant widely distributed in Eurasia. Where it is cultivated as a crop, it is normally harvested in a sustainable manner, although there are some concerns that the commercial harvest of rhizomes can be destructive to naturally occurring populations and their habitats.
Glycyrrhiza glabra contains the compound glycyrrhizin, which is 50 times sweeter than sugar. It was well known by the ancient Greeks and Romans for its sweetness and is still a popular flavouring for confectionery today. Cultivated as a crop plant, the underground stems (rhizomes) of G. glabra are harvested and the juice extracted before being concentrated by boiling. The solid extract is used in confectionery, such as traditional liquorice sticks and wheels.
Liquorice is used in the production of drinks, for example as an ingredient in many root beers, and some brewers use it to colour stout (a dark beer made using roasted malt or barley).
It is also used in plug tobacco (a form of chewing tobacco), shoe polish and soap and as a fibre for the production of plastics and fibreboard. Spent liquorice rhizomes (underground stems) are used in fire-extinguishing agents and as compost for growing mushrooms.
Alkaline, sandy but moist soil is preferable.
