Liquorice root | Glycyrrhiza glabra | Organic


Liquorice root is a prized herbal remedy, with a long history of traditional use and many actions which make it valuable for a variety of different applications. It has a very sweet taste, approximately 50 times sweeter than sucrose, hence its latin name Glycyrrhiza.

It is extremely useful as a demulcent, soothing the digestive tract and the lungs due to its polysaccharide component. It is used for cough remedies – see our blog here about this subject.

The Triperpeonoid saponins have adrenocorticoid actions where they reduce the conversion of cortisol to inactive cortisone, making the cortisol effectively active for longer without explicitly raising the plasma levels. This creates an anti-inflammatory action due to the effect of cortisol on inflammation. However this can create side effects so Liquoice root is contra-indicated in those who are sensitive to the effects of mineralocorticoids such as those with obesity, fluid retention, high blood pressure, high sodium and low potassium levels. Glycyrrhizin also directly binds to the gluco-corticoid receptors weakly initiating its effects. Liquorice can lower potassium levels which adds to its list of contraindications including those with kidney disease.

Liquorice can also lower testosterone levels which makes it useful for women with hirsutism, however in some studies it has not affected plasma testosterone levels significantly.

Immunity – Liquorice root has been shown to increase interferon levels, as well as enhance T-cell production within 24 hours and it also has antiviral, anti-fungal and antibacterial actions towards the following: Helicobacter pylori, Streptococcus mutans, Propionibacterium acnes, Staphylococcus aureus, Enterococcus faecalis, Bacillus subtilis, Micrococcus luteus, Mycobacterium tuberculosis, Legionella spp, Trichophyton mentagrophytes, Candida albicans, Epstein Barr, HSV, SARS1, HIV, Hepatitis B.

Liquorice root has a hepatoprotective action either through antiviral effects directly or via antioxidant pathways as well.

There is also some potential for components of Liquorice root having antiviral action against SARSCov2 which is currently being researched (5) (6) (7).

As an anti-inflammatory Liquorice root has been studied using a placebo controlled trial against Ibuprofen for dysmenorrhea and has been shown to be as effective in relieving pain (8).

Several flavonoids from Liquorice root have antioxidant effect in vitro and the Isoflavones glabridin and glabrene also have endocrine effects benefiting post-menopausal women.
