Licorice Root
Glycyrrhiza glabra
Traditional Uses
Digestive & Gastrointestinal Health:
Licorice root is renowned for its soothing and healing effects on the digestive tract. It helps relieve heartburn, acid reflux, and indigestion by lowering stomach acid and protecting the mucous membranes. Its key active compound, glycyrrhizin, promotes ulcer healing and reduces inflammation in the stomach and intestines. It can also act as a mild laxative, supporting gentle elimination and healthy bile flow from the liver.
Liver Support & Detoxification:
Licorice enhances liver function by increasing bile secretion and supporting detoxification. Its antioxidant and anti-inflammatory properties help protect liver tissue and may assist in managing conditions such as hepatitis and fatty liver. By boosting levels of interferon — a key immune system protein — it helps the body defend against viral infections that can impact the liver.
Respiratory Health:
In the respiratory system, licorice acts as a soothing expectorant, helping to thin and expel mucus while calming coughs and throat irritation. It’s particularly beneficial for bronchitis, asthma, emphysema, and other inflammatory respiratory conditions. Its natural antiviral and antibacterial compounds help combat infections, making it a valuable ally during colds and flu.
Stress & Adrenal Support:
Licorice root is well known for supporting adrenal gland function. Glycyrrhizin helps prevent the breakdown of cortisol, the body’s primary stress hormone, making it more available during times of fatigue or prolonged stress. This adaptogenic action helps improve resilience, energy levels, and recovery during physical or emotional strain.
Hormonal & Menstrual Balance:
Licorice contains phytoestrogens — plant-based compounds that mimic mild estrogenic activity — making it useful for easing PMS and menopausal symptoms such as bloating, irritability, and breast tenderness. Its hormone-modulating effects help maintain balance during the menstrual cycle while supporting emotional and physical wellbeing.
Immune & Antiviral Action:
Licorice boosts immunity by increasing interferon levels and providing potent antiviral compounds that inhibit the growth of viruses such as influenza A and herpes simplex. Its antibacterial and antifungal properties make it effective for combating infections, including sore throats, yeast overgrowth, and gum inflammation.
Inflammation & Pain Relief:
Licorice’s natural anti-inflammatory effects make it useful in relieving joint pain, arthritis, and bursitis. Acting similarly to aspirin, it helps reduce fevers, headaches, and allergic reactions. Its anti-allergenic properties may benefit conditions such as hay fever, allergic rhinitis, and conjunctivitis.
Cardiovascular Support:
Research indicates that licorice may protect the heart by limiting oxidative damage from LDL (“bad”) cholesterol, helping prevent plaque buildup and supporting healthy blood vessels. Modest doses (around 100 mg daily) have been shown to encourage better cardiovascular function.
Mood & Fatigue Support:
Licorice root contains several natural compounds with antidepressant effects, making it a useful herbal alternative to St. John’s Wort for mild depression and chronic fatigue. By enhancing cortisol activity and stabilising blood sugar, it promotes sustained energy and improved mood balance.
How It Works:
Licorice’s primary therapeutic compound, glycyrrhizin, is up to 50 times sweeter than sugar and plays a central role in the herb’s broad range of effects. It modulates adrenal hormone metabolism, supports mucous membrane healing, and provides antiviral, antibacterial, and anti-inflammatory actions. The root also contains flavonoids, phytoestrogens, and antioxidants that contribute to its restorative effects.
Cautions:
Prolonged or excessive use of licorice (especially glycyrrhizin-containing forms) may cause water retention, high blood pressure, or reduced potassium levels. Individuals with hypertension, kidney disease, or heart conditions should use it under professional guidance. Pregnant or breastfeeding individuals and those taking corticosteroids or diuretics should consult a healthcare practitioner before use.
