Part supplied

The chopped root.

Food Use

Liquorice is a popular addition to herbal tea blends, especially in digestifs taken after meals to support sensitive digestion and pick-me-up blends. The whole root can be chewed and is a pleasant, low-calorie alternative to sweets, enjoyed by both children and adults.


Use 1 teaspoon of dried herb to one cup of boiling water to make a tasty tea. Infuse for 5-10 minutes. Sweeten with honey or lemon to taste.

Alternatively add half a teaspoon (2.5 ml) of tincture to a cup of warm water for a quick alternative to tea.

The herb can be added as a flavouring to gin, vodka and other infusions.

Medicinal Use

Liquorice has traditionally been used as an anti-inflammatory, expectorant, laxative and supportive tonic for the adrenal glands. It is considered to be a synergistic herb and often incorporated as a flavouring in traditional herbal medicines. It is an active ingredient in our historic licenced Sage and Garlic Catarrh Remedy which contains the equivalent of 550 mg of Liquorice root per 5 ml dose to soothe coughs and encourage the expulsion of mucus. It was often incorporated into throat lozenges in the past for this reason.

Key actions: Demulcent, expectorant, adrenal tonic, anti-inflammatory.

In clinic: Herbalists use this herb to treat adrenal insufficiency, bronchitis, gastritis and peptic ulceration.
