Licorice Root Tea Benefits: 7 Science-Backed Benefits (2025)
For thousands of years, licorice root has been one of the most treasured herbs in traditional medicine systems across Asia, Europe, and the Middle East. This remarkable root, known scientifically as Glycyrrhiza glabra, has been used since ancient Egyptian times—historians note it was even found in King Tutankhamun’s tomb. Today, licorice root tea continues to gain popularity as people discover its impressive range of potential health benefits. From soothing digestive issues to supporting respiratory health, this naturally sweet herb offers a gentle, delicious way to support your daily wellness routine. Research published in journals like Phytotherapy Research and Journal of Ethnopharmacology has begun validating many of these traditional uses, revealing why licorice root has earned its reputation as a healing superfood.

What is Licorice Root Tea?
Licorice root tea is an herbal infusion made from the dried root of the Glycyrrhiza glabra plant, a member of the legume family native to Western Asia, Southern Europe, and parts of the Mediterranean. The root contains a compound called glycyrrhizin, which is approximately 50 times sweeter than sugar—this is what gives the tea its distinctive sweet, slightly earthy flavor profile. Traditional Chinese Medicine refers to licorice root as “Gan Cao” and uses it as a harmonizing herb in many formulas, while Ayurvedic medicine has long valued it for its cooling and nourishing properties. Licorice root is also a key component in Japanese “Kampo” medicine and has been a staple in European herbalism for centuries. The tea is typically prepared by steeping dried licorice root slices or powder in hot water for 5-10 minutes, producing a golden-brown brew with a uniquely sweet taste that many people find naturally appealing without needing additional sweeteners.
Top 7 Benefits of Licorice Root Tea
1. Supports Digestive Health and Soothes Stomach Discomfort
Licorice root tea has been traditionally used to address various digestive complaints, and modern research is confirming these benefits. The glycyrrhizin compound in licorice root has been shown to have anti-inflammatory effects on the stomach lining, potentially helping to soothe irritation and discomfort. A study published in the Journal of Ethnopharmacology found that licorice root extract helped protect the gastric mucosa and promoted mucus secretion, which can be beneficial for those dealing with occasional heartburn or indigestion. The demulcent properties of licorice root—meaning it forms a soothing film over mucous membranes—can provide gentle relief for an upset stomach. Many people find that drinking a cup of licorice root tea after meals helps support comfortable digestion.
2. May Help Reduce Acid Reflux and Heartburn Symptoms
Licorice root tea has gained attention for its potential to help manage acid reflux and heartburn symptoms naturally. Unlike conventional antacids that simply neutralize stomach acid, licorice root may help address the underlying inflammation that can contribute to these uncomfortable symptoms. Research published in Phytotherapy Research demonstrated that deglycyrrhizinated licorice (DGL) extract was effective in reducing symptoms of acid reflux when used over a 30-day period. The soothing properties of licorice root tea can help calm the esophageal lining and support the body’s natural digestive processes. However, it’s important to note that whole licorice root (not DGL) contains glycyrrhizin, which may not be suitable for everyone—those with acid reflux should consider this when choosing their product.
3. Supports Respiratory Health and Soothes Sore Throats
Licorice root has a long history of use for supporting respiratory health, particularly for soothing sore throats and calming irritated airways. The herb contains compounds that have demonstrated expectorant properties, meaning it may help loosen and clear mucus from the respiratory tract. In traditional Chinese Medicine, licorice root is frequently included in formulas designed to address coughs and bronchial congestion. A study in the International Journal of Molecular Sciences highlighted glycyrrhizin’s anti-viral properties, suggesting it may help the body fight off respiratory infections. Gargling with cooled licorice root tea has been a folk remedy for sore throats for generations, and modern herbalists continue to recommend this practice for its soothing effects on the throat tissue.
4. May Support Immune System Function
Licorice root contains bioactive compounds that have been studied for their potential immune-modulating effects. Glycyrrhizin and related flavonoids in licorice root have demonstrated antiviral, antimicrobial, and anti-inflammatory properties in various scientific studies. Research published in Biomedicine & Pharmacotherapy found that licorice root compounds showed activity against several strains of influenza virus and other respiratory pathogens. Additionally, licorice root may help support the body’s natural cortisol production, which plays a role in the stress response and overall immune function. Regular consumption of licorice root tea during seasonal changes may offer general wellness support, though it should not replace medical treatment for any condition.
5. Supports Liver Health and Detoxification
The liver-protective properties of licorice root have been documented in numerous scientific studies. Glycyrrhizin has been shown to have hepatoprotective effects, helping to protect liver cells from damage caused by toxins, medications, and oxidative stress. A study published in the Journal of Pharmacy and Pharmacology found that licorice root extract helped reduce markers of liver damage in animal models. In traditional medicine systems, licorice root is often used to support the liver’s natural detoxification pathways. The antioxidant compounds in licorice root may also help neutralize free radicals that can damage liver tissue over time. While more human studies are needed, these preliminary findings suggest licorice root tea may be a supportive addition to a liver-healthy lifestyle.
6. May Help Reduce Stress and Support Adrenal Function
Licorice root has adaptogenic properties, meaning it may help the body cope with physical and mental stress more effectively. The herb appears to support the adrenal glands and may help regulate cortisol—the primary stress hormone—in a way that promotes more balanced energy levels throughout the day. Research in Endocrine Regulations has explored the relationship between glycyrrhizin and the hypothalamic-pituitary-adrenal (HPA) axis, which controls the body’s stress response. People experiencing fatigue or burnout may find that licorice root tea helps support their energy and resilience. However, due to its effects on cortisol and blood pressure, those with certain health conditions should use caution and consult with a healthcare provider before using licorice root for stress support.
7. Promotes Healthy Skin and May Help with Eczema
Licorice root contains compounds that have shown promise in supporting skin health, particularly for conditions like eczema and minor skin irritations. The anti-inflammatory and antimicrobial properties of licorice root make it a popular ingredient in natural skincare products. Topical application of licorice root extract has been studied for its effects on atopic dermatitis, with research published in Dermatology showing reduced inflammation and itching. Drinking licorice root tea may also support skin health from within due to its anti-inflammatory effects. Additionally, the antioxidant content in licorice root may help protect skin from environmental damage and support a healthy, radiant complexion. More research is needed to fully understand the skin benefits of oral consumption, but the traditional use of licorice root for skin health is well-documented.
How to Prepare Licorice Root Tea
Preparing licorice root tea is simple and straightforward. Start with 1-2 grams of dried licorice root per cup of water (or use one pre-bagged tea). Bring fresh water to a boil, then let it cool for approximately 30 seconds—this prevents the delicate compounds in licorice root from being damaged by rolling boiling water. Pour the hot water over the licorice root and allow it to steep for 5-10 minutes, depending on how strong you prefer the flavor. The longer you steep, the more pronounced the sweet, earthy flavor will become. You can enjoy licorice root tea plain, or add a small amount of honey if desired. For a more complex flavor profile, try blending licorice root with other herbs like ginger or peppermint. It’s generally recommended to limit consumption to 1-2 cups per day and to take periodic breaks from daily use.
Side Effects and Precautions
While licorice root tea offers many potential benefits, it’s important to be aware of certain precautions. The compound glycyrrhizin can cause the body to retain sodium and lose potassium, which may lead to increased blood pressure in some individuals. Those with hypertension, heart disease, or kidney problems should exercise particular caution and consult with a healthcare provider before regularly consuming licorice root tea. The FDA recommends that excessive consumption of glycyrrhizin (more than 50 grams of licorice daily for several weeks) may cause serious health issues. Pregnant and breastfeeding women should avoid licorice root tea due to insufficient safety data. Those taking medications—including blood pressure medications, diuretics, corticosteroids, or blood thinners—should speak with their doctor before using licorice root. For those concerned about glycyrrhizin’s effects, deglycyrrhizinated licorice (DGL) products are available as an alternative.
