Liquorice root

Liquorice root comes from the perennial herb Glycyrrhiza glabra, native to southern Europe and parts of Asia. The root is dried and can be used whole, cut, or powdered. It has a distinctive sweet flavour, often described as anise-like.

Liquorice root is primarily used as a flavouring agent in foods and beverages, particularly in confectionery, teas, and some alcoholic drinks. Its natural sweetness means it can also contribute to the sweet taste profile of products. It is commonly found in herbal teas and some speciality teas.

Liquorice root is not an authorised food additive in the UK and is used for its flavouring properties. The consumption of large quantities of liquorice root, particularly from processed foods containing added liquorice extract, has been associated with potential health effects such as increased blood pressure and lowered potassium levels. These effects are mainly linked to glycyrrhizin, a compound found in liquorice root. EFSA has evaluated flavourings, and liquorice root is considered a flavouring substance. The UK's Food Standards Agency and Food Standards Scotland provide guidance on healthy eating, advising moderation in the consumption of foods high in sugar and salt.
