Licorice: Flavoring Agent with Medicinal Potential and Health Considerations

Licorice, extracted from the root of the Glycyrrhiza glabra plant, has long been valued both as a sweetening agent and a traditional herbal remedy. Its primary active compound, glycyrrhizin, is 30 to 50 times sweeter than sucrose, making it highly effective in sub-therapeutic amounts across various applications. This natural sweetness has secured licorice a role in flavoring herbal medicines, lozenges, and tobacco products.

In herbal medicine, licorice root is commonly included not only for its taste-enhancing properties but also for its soothing and demulcent effects. It is widely used in syrups and teas aimed at relieving cough, sore throat, acid reflux, and mild gastrointestinal discomfort. Recent studies also highlight its potential anti-inflammatory, antioxidant, and antiviral activities, attributed to glycyrrhizin and flavonoid constituents. These findings support its inclusion in certain complementary therapies for conditions such as eczema, peptic ulcers, and respiratory infections.

In the tobacco industry, licorice is added to products like chewing tobacco and pipe blends to improve flavor, enhance aroma, and maintain moisture. Its ability to mask bitterness also improves product palatability.

However, despite its benefits, licorice poses risks when consumed in large quantities. Glycyrrhizin can inhibit the enzyme 11β-hydroxysteroid dehydrogenase, leading to increased cortisol activity, which may result in hypertension, hypokalemia (low potassium), and water retention. The U.S. FDA and European health agencies caution against excessive daily intake, especially for individuals with cardiovascular, renal, or metabolic disorders.

In conclusion, while licorice remains generally safe in sub-therapeutic doses and continues to be a valuable flavoring and medicinal component, consumers and manufacturers must remain aware of its physiological impact. Ongoing research may further clarify its therapeutic potential and help define safe usage guidelines in both food and medical contexts.

Licorice: History and Use

History of licorice as herbal drink

Licorices are believed to have originated in southern Asia and then spreading through the Middle East and into southern Europe, licorice is first reported in England as growing at a monastery in Pontefract, from whence its fame spread to the States and beyond.

The first documented medicinal use of licorice can be traced back to ancient Assyrian, Egyptians, Chinese and Indian cultures. Ancient Egyptians prepared a licorice drink for ritual use to honor spirits of the pharaohs. It was used in ancient Greece, China, and Egypt, primarily for gastritis and ailments of the upper respiratory tract.

According to Theophrastus (IV–III century b.c.), the great botanist, pharmacologist and disciple of Plato and Aristotle, the Greeks probably learnt about the pharmacological uses of licorice from the Scythians, an ethnic group who lived to the north and east of Greece in the area of the Ukraine between the Black and Caspian Seas.

Plinius the Elder suggested licorice as a remedy for asthma, malaises and the throat, ulcerations of the mouth, and even advised its use to combat sterility.

Its usage has also evolved over the years. From the licorice juice ancient people mixed into drinks as medicine and wasn’t until around the 13th century CE that licorice started appearing in confectionary.

During World War II, the Dutch physician F.E. Revers observed improvements in patients' peptic ulcer disease from a licorice preparation. He also noted facial and peripheral edema, sparking scientific investigation into licorice's properties and adverse effects. In the 1950s, there were reports of patients with Addison's disease 'craving' licorice candy, viewed by some as early evidence of steroid modulating properties.

Licorice: Uses and Health Benefits

Herbal Drinks
Licorice is harvested from the root and dried rhizomes of the low-growing shrub Glycyrrhiza glabra . Currently, most licorice is produced in Greece, Turkey, and Asia.
Licorice was used in ancient Greece, China, and Egypt, primarily for gastritis and ailments of the upper respiratory tract. Ancient Egyptians prepared a licorice drink for ritual use to honor spirits of the pharaohs. Its use became widespread in Europe and Asia for numerous indications.
During World War II, the Dutch physician F.E. Revers observed improvements in patients' peptic ulcer disease from a licorice preparation. He also noted facial and peripheral edema, sparking scientific investigation into licorice's properties and adverse effects. In the 1950s, there were reports of patients with Addison's disease 'craving' licorice candy, viewed by some as early evidence of steroid modulating properties.

In addition to its medicinal uses, licorice has been used as a flavoring agent, valued for sweetness (glycyrrhizin, a component of licorice, is 50 times sweeter than table sugar). The generic name "glycyrrhiza" stems from ancient Greek, meaning "sweet root." It was originally used as flavoring for licorice candies, although most licorice candy is now flavored with anise oil. Licorice is still used in sub-therapeutic doses as a sweetening agent in herbal medicines, lozenges, and tobacco products (doses low enough that significant adverse effects are unlikely).

Licorice has a long history of medicinal use in Europe and Asia. At high doses, there are potentially severe side effects, including hypertension (high blood pressure), hypokalemia (low blood potassium levels) and fluid retention.Most adverse effects have been attributed to the chemical component glycyrrhiza (or glycyrrhizic acid). Licorice can be processed to remove the glycyrrhiza, resulting in DGL (deglycyrrhizinated licorice), which does not appear to share the metabolic disadvantages of licorice.

In Europe, licorice has most often been used to treat cough, bronchitis, gastritis, and peptic ulcer disease. In Chinese medicine, it is felt to benefit Qi , reduce "Fire Poison" (sore throat, skin eruptions), and diminish "Heat." Specific conditions treated by Chinese herbalists include gastric and duodenal ulcers, abdominal pain, pharyngitis, malaria, tuberculosis, abscesses and sores. In Ayurveda, licorice is felt to be effective in the treatment of constipation, inflamed joints, peptic ulcer disease, and diseases of the eye.

Uses based on scientific evidence

Apthous ulcers / canker sores
Some research suggests that licorice extracts, DGL and carbenoxolone may provide benefits for treating cankers sores. However, studies have been small, with flaws in their designs. The safety of DGL makes it an attractive therapy if it does speed healing of these sores, but it is not clear at this time whether there is truly any benefit.

Atopic dermatitis
Topical licorice extract gel has been shown to be effective in the treatment of atopic dermatitis in preliminary human study. Further research is needed to confirm these results.


Bleeding stomach ulcers caused by aspirinAlthough there has been some study of DGL in this area, it is not clear what effects DGL has on gastrointestinal bleeding.

Familial Mediterranean Fever (FMF)
A small clinical pilot study and laboratory study of a multi-ingredient preparation containing licorice, called Immunoguard, suggests possible effects in managing FMF. Well-designed study of licorice alone is necessary before a recommendation can be made.

Herpes simplex virus
Laboratory studies have found that DGL may hinder the spread and infection of herpes simplex virus. Studies in humans have been small, but they suggest that topical application of carbenoxolone cream may improve healing and prevent recurrence.


High potassium levels resulting from abnormally low aldosterone levels
In theory, because of the known effects of licorice, there may be some benefits of licorice for high potassium levels caused by a condition called hypoaldosteronism. There is early evidence in humans in support of this use. However, research is preliminary and a qualified health care provider should supervise treatment.


Peptic ulcer disease
Licorice extracts, DGL and carbenoxolone have been studied for treating peptic ulcers. DGL (but not carbenoxolone) may offer some benefits. However, these studies have been small, with flaws in their designs, and results of different studies have disagreed with each other. Therefore, it is unclear whether there is any benefit from licorice for this condition.

Reducing body fat mass
Preliminary data shows that licorice may reduce body fat mass. Further research is needed to confirm these results.

Viral hepatitis
The licorice extracts DGL and carbenoxolone have been proposed as possible therapies for viral hepatitis. Animal studies have investigated the mechanism of licorice in hepatitis, and studies in humans have shown some benefits with a patented intravenous licorice preparation that is not available in the United States. Studies using oral licorice have been small, with flaws in their designs. Therefore, it is not clear whether there is any benefit from oral licorice for hepatitis treatment.

Genital herpes
Available studies have not found any benefit from carbenoxolone cream when applied topically to the skin to treat genital herpes infections.
