Liquorice (Template:PronEng Template:Respell),[1] also licorice, is the root of Glycyrrhiza glabra from which a sweet flavour can be extracted. The liquorice plant is a legume (related to beans and peas), native to southern Europe and parts of Asia. It is not related to Anise, Star Anise or Fennel, which are the source of superficially similar flavouring compounds. It is an herbaceous perennial, growing to 1 m in height, with pinnate leaves about 7–15 centimetres (3–6 in) long, with 9–17 leaflets. The flowers are 0.8–1.2 cm (½–⅓ in) long, purple to pale whitish blue, produced in a loose inflorescence. The fruit is an oblong pod, 2–3 centimetres (1 in) long, containing several seeds.[2] The flavor of liquorice comes mainly from a sweet-tasting compound called anethole ("trans"-1-methoxy-4-(prop-1-enyl)benzene), an aromatic, unsaturated ether compound also found in anise, fennel, and other herbs. Additional sweetness in liquorice comes from glycyrrhizin, a compound sweeter than sugar.

Excessive consumption of liquorice or liquorice candy is known to be toxic to the liver[3] and cardiovascular system, and may produce hypertension [4] and oedema.[5] The European Commission 2008 report suggested that “people should not consume any more than 100mg of glycyrrhizic acid a day, for it can raise blood pressure or cause muscle weakness, chronic fatigue, headaches or swelling, and lower testosterone levels in men.”

Liquorice grows best in deep, fertile, well-drained soils, with full sun, and is harvested in the autumn, two to three years after planting.[2]
