What Is Licorice?
Licorice is a wild plant native to Southern Europe, Western Asia, and North Africa. It belongs to the bean family and derives its name from a Greek-Latin term meaning “sweet root.” This herb has a long history, with its use dating back to ancient Egypt, where it was prized for making sweet drinks. Egyptian rulers, including King Tut, included licorice in their treasures due to its perceived value.
Licorice plants grow between 1 to 1.5 meters tall, with purple to light blue flowers and extensive roots, including taproots and runners. The roots are light brown, flexible, and soft, while the plant has small, rounded leaves. Licorice thrives in sunny, dry climates, tolerates drought, and requires well-drained soil with minimal watering. It is an easy-to-grow perennial plant that is harvested in autumn, typically 2–3 years after planting.
Geographical Distribution and Trade
Licorice is cultivated in China, Iran, Turkey, Iraq, Italy, Pakistan, India, and other countries. Major importers in Europe include Germany, France, Italy, the Netherlands, the United Kingdom, and Finland. Licorice’s appearance and type vary by origin; for example, Spanish licorice is sold as unpeeled runners, while Russian licorice comes in peeled pieces.
Nutritional and Structural Components
Research shows that licorice contains:
- 20 Triterpenoids and Nearly 300 Flavonoids:
- Triterpenoids: Natural glycosides with bioactive properties.
- Flavonoids: Polyphenolic compounds found in flowers, tea leaves, grains, fruits, and vegetables, known for their antioxidant, anti-inflammatory, and anti-cancer effects.
- Minerals: Phosphorus, calcium, iron, magnesium, potassium, and others contribute to its nutritional value.
Licorice’s Sweetness
Licorice’s distinct sweetness is due to glycyrrhizin, a compound 50 times sweeter than sugar. This makes licorice a popular natural sweetener in various industries.
Licorice’s versatility, nutrient-rich composition, and history of use make it a valuable resource in modern medicine, food, and other industries.

Licorice Effects on Our Health and Body
Licorice (Glycyrrhiza glabra) has been widely recognized for its medicinal properties and positive effects on various health conditions. Below are the key health benefits of licorice:
Digestive Health
Licorice root, primarily through its active compound glycyrrhizin, is effective in treating:
- Stomach pain, indigestion, and heartburn
- Acid reflux and peptic ulcers, which are often caused by bacterial inflammation. Glycyrrhizin aids in healing and reducing inflammation in the stomach lining.
Respiratory Health
Licorice acts as an expectorant, helping to remove excess mucus from the airways. It has also been used to treat bronchial asthma and slow the progression of bronchitis, thanks to its glycyrrhizic, asiatic, and oleanolic acids.
Skin Health
Licorice’s antibacterial, antiviral, and anti-inflammatory properties make it effective for improving skin conditions such as:
- Eczema and psoriasis, by reducing redness, irritation, and itchiness.
- Wound healing, promoting faster recovery.
Dental Health
Licorice root is a natural remedy for oral diseases, including:
- Aphthous ulcers (canker sores)
- Gingivitis (gum inflammation)
- Dental caries (tooth decay)
- Periodontitis (gum disease)
Antibacterial and Antiviral Properties
Licorice contains flavonoids and compounds like GL (glycyrrhizin) and GA (glycyrrhetinic acid), which:
- Inhibit bacterial infections.
- Weaken viral activity by interfering with virus replication and gene expression.
Menopausal Symptom Relief
Research on menopausal women shows that licorice root helps reduce hot flashes and other menopausal symptoms by regulating hormonal fluctuations.
Liver Health
Licorice is effective in managing Hepatitis C, as glycyrrhizin controls the disease’s progression and helps prevent cirrhosis. It also supports liver health by breaking down cortisol, a stress hormone.
Anti-Fungal and Anti-Cancer Effects
Licorice contains glabridin, an antifungal compound that slows the growth of bacteria and viruses. Additionally, licorice may reduce the growth of cancer cells in conditions such as:
- Breast cancer
- Prostate cancer
- Other forms of cancer.
Stress Management
Licorice helps regulate adrenal gland function, balancing cortisol levels and combating stress. This results in better energy management and improved reactions during stressful situations.
Conclusion
Licorice is a potent natural remedy with a wide range of health benefits, from aiding digestion and improving respiratory health to managing skin conditions, liver health, and stress. Its unique combination of glycyrrhizin, glabridin, flavonoids, and other bioactive compounds makes it a valuable addition to traditional and modern medicine.
Licorice
Excessive Consumption of Licorice
Licorice should be consumed in moderation as overuse can cause side effects, primarily due to glycyrrhizic acid. Prolonged or excessive intake may lead to:
- High blood pressure and low potassium levels, particularly dangerous for individuals with hypertension, kidney, or heart issues.
- Muscle weakness, fatigue, and irregular heart rhythms.
- Rare cases of licorice poisoning, causing kidney dysfunction.
Pregnancy and Breastfeeding: Women should consult their doctor to determine safe licorice consumption during these periods.
Conclusion
Consume licorice within recommended doses to avoid health risks, especially for vulnerable individuals.
The World Health Organization (WHO) and the European Scientific Committee of Food (SCF) recommend limiting glycyrrhizin intake to 100 mg per day to avoid potential side effects.
Medication Interactions
Licorice can interact with medications such as:
- Blood pressure drugs
- Warfarin (blood thinner)
- Anti-cholesterol medications
- Estrogen-based contraceptives
If you are on any of these medications, consult your doctor before consuming licorice.
DGL (Deglycyrrhizinated Licorice)
DGL is a processed form of licorice with significantly lower glycyrrhizin levels, making it safer for long-term use and reducing the risk of drug interactions.
Research from 2014 found that DGL promotes mucus production, which helps protect the stomach lining and acts as a barrier against acid reflux. This makes DGL an effective treatment for peptic ulcers and acid reflux.
Conclusion
To safely consume licorice, follow recommended glycyrrhizin limits, consult a doctor if taking medications, and consider DGL as a safer alternative for prolonged use.
