Licorice root is one of the most widely recognized traditional herbal ingredients, valued for its naturally sweet flavor and long history of use in herbal medicine. Also known simply as licorice, the root has traditionally been used in teas, herbal formulas, throat preparations, and food products. Today, licorice root is available as dried root, powder, tea, extracts, and supplements, but understanding its potential benefits and safety is important before using concentrated products.
1. What Is Licorice Root?
Licorice root comes from plants in the Glycyrrhiza genus, including Glycyrrhiza glabra, one of the best-known species used in herbal products. The plant is a perennial herb in the legume family and develops long underground roots and rhizomes.
The root is the primary part traditionally harvested and used. It contains naturally occurring compounds that give licorice root its characteristic sweetness. One of the most important is glycyrrhizin, also known as glycyrrhizic acid.
Licorice root has a long history in European, Middle Eastern, Chinese, and other Asian herbal traditions. It has been used in traditional preparations for digestive comfort, respiratory and throat support, and general herbal wellness.
Today, licorice root can be found in herbal teas, powders, capsules, extracts, lozenges, and topical products. It is also used as a natural flavoring ingredient in certain foods and beverages.
It is worth noting that products with a “licorice flavor” do not always contain real licorice root. Some foods use anise or other flavoring ingredients instead.
2. Licorice Root Benefits and Uses
Licorice root benefits have been discussed for centuries in traditional herbal medicine. The root contains several biologically active plant compounds, including glycyrrhizin and flavonoids, which have been studied in laboratory and human research.
However, traditional use and scientific evidence are not the same. Some potential uses of licorice root have been investigated, but evidence remains limited for many health claims. Licorice root should therefore not be viewed as a proven treatment for a specific disease.
Traditional Digestive Uses
One of the best-known traditional uses of licorice root is in digestive herbal preparations. It has historically been combined with other herbs in formulas intended to support stomach and digestive comfort.
Some research has examined licorice-containing preparations for digestive symptoms. However, many studies involve products containing several herbs or ingredients, so it is not always possible to determine whether licorice root itself produced the observed effects.
For this reason, licorice root is better described as a traditional digestive herb rather than a clinically established treatment.
Traditional Respiratory Uses
Licorice root has also been traditionally used in preparations for the respiratory system. Herbal teas, syrups, and formulas containing licorice root have historically been used to soothe the throat and support respiratory comfort.
Its naturally sweet taste makes it particularly useful in herbal preparations intended for the throat.
Although researchers have studied compounds found in licorice root for various biological activities, there is not enough reliable evidence to establish licorice root as a treatment for respiratory diseases.
Throat and Mouth Uses
Another area of interest is the use of licorice root in oral and throat preparations.
Preliminary research has examined licorice-containing mouth rinses, gargles, and other preparations. Some studies have also explored licorice for temporary throat discomfort and recurrent canker sores.
These findings are promising but limited. More high-quality human research is needed before licorice root can be considered an established treatment for oral or throat conditions.
Skin-Related Uses
Licorice root is also found in some creams, gels, and cosmetic products. Certain compounds from the root have been investigated for their potential effects on the skin.
Traditional preparations containing licorice root have been used for various skin-related concerns, while modern research has explored specific licorice compounds in topical applications.
However, different products can contain different concentrations and additional ingredients. People with persistent or serious skin problems should seek professional medical advice rather than relying solely on licorice root products.
Antioxidant Plant Compounds
Licorice root contains several naturally occurring compounds, including flavonoids, saponins, and glycyrrhizin.
Laboratory studies have investigated the biological activity of these compounds, including their antioxidant-related properties. However, laboratory findings cannot automatically be translated into proven health benefits in humans.
This distinction is important when evaluating claims about licorice root benefits.
Common Uses of Licorice Root
Traditionally, licorice root has been used in:
- Herbal teas
- Traditional digestive formulas
- Throat preparations
- Herbal syrups
- Mouth rinses
- Lozenges
- Botanical extracts
- Topical products
- Food and beverage flavoring
- Multi-herb formulas
Overall, licorice root has an extensive history of traditional use, but modern evidence is still developing.
3. How to Take Licorice Root
Licorice root is available in several forms, including dried root, tea, powder, capsules, extracts, and DGL products. The appropriate form depends on the intended use and the specific product.
Licorice Root Tea
Dried licorice root can be prepared as an herbal tea. Some teas contain licorice root as the main ingredient, while others combine it with herbs such as peppermint, ginger, or chamomile.
The concentration of glycyrrhizin can vary between products, so different licorice teas may not have the same strength.
Because regular exposure to high amounts of glycyrrhizin can cause health problems, licorice root tea should not automatically be treated like an ordinary beverage for unlimited daily use.
Licorice Root Powder
Dried licorice root can also be ground into powder. Licorice root powder is used in traditional herbal preparations and may be included in capsules or blended into other products.
Follow the instructions provided by the manufacturer and avoid assuming that larger amounts provide greater benefits.
Licorice Root Extract
Licorice root extracts are more concentrated than dried root or tea. They may be available as liquid extracts, capsules, tablets, or other supplements.
Concentrated extracts require additional caution because they may contain substantially higher amounts of active compounds.
Always check the product label for information about glycyrrhizin and follow the recommended directions.
DGL Licorice Root
DGL, or deglycyrrhizinated licorice, is licorice that has been processed to remove or substantially reduce glycyrrhizin.
This makes DGL different from conventional licorice root products. However, DGL products can vary, so consumers should carefully read the label and use them according to product directions.
4. Licorice Root Side Effects & Safety
Although licorice root has a long history of traditional use, it is not risk-free. The main safety concern is glycyrrhizin, particularly when licorice root is consumed in large amounts or for an extended period.
Excessive glycyrrhizin intake can affect blood pressure, potassium levels, and fluid balance. In serious cases, these effects may contribute to abnormal heart rhythms and cardiovascular complications.
Potential side effects associated with excessive consumption of glycyrrhizin-containing licorice root include:
- Increased blood pressure
- Low potassium levels
- Fluid retention
- Swelling
- Weakness
- Muscle-related symptoms
- Abnormal heart rhythm
- Cardiovascular complications
The risk can be greater for people who already have high blood pressure, heart disease, kidney disease, or conditions involving electrolyte balance.
Licorice Root and Medication Interactions
Licorice root may interact with certain medications. People taking prescription or over-the-counter medicines should speak with a healthcare professional before using concentrated licorice root supplements.
This is particularly important for medications that affect blood pressure, potassium, fluid balance, or corticosteroids.
Licorice Root During Pregnancy
Large amounts of oral licorice root, especially concentrated extracts, should be avoided during pregnancy unless specifically recommended by a qualified healthcare professional.
People who are breastfeeding should also seek professional guidance because safety information for concentrated licorice products is limited.
The amount of licorice used as a food flavoring is different from the amount found in concentrated herbal supplements.
5. Who May Consider Using Licorice Root?
Licorice root may be of interest to adults who want to explore traditional herbal ingredients or use licorice as part of teas, foods, or botanical preparations.
It may also be relevant to people researching traditional herbal approaches related to:
- Digestive comfort
- Throat and respiratory preparations
- Herbal teas
- Oral-care products
- Traditional skin preparations
However, the intended use matters. A small amount of licorice root used as a food ingredient is very different from a concentrated extract or supplement.
People considering licorice root for a specific health concern should review the available evidence and discuss concentrated products with a healthcare professional.
It is also important to check whether the product contains glycyrrhizin, because this compound is responsible for many of the safety concerns associated with regular licorice root.
6. Who Should Avoid Licorice Root?
Some people should avoid regular or concentrated licorice root products because glycyrrhizin can affect blood pressure, potassium, and fluid balance.
Extra caution is recommended for people with:
- High blood pressure
- Heart disease
- Kidney disease
- Low potassium levels
- Electrolyte disorders
- Fluid retention
- Conditions affected by sodium or potassium balance
Pregnant people should avoid large amounts of oral licorice root, particularly concentrated extracts. Those who are breastfeeding should discuss licorice supplements with a healthcare professional before use.
People taking medications should also check for potential interactions before using concentrated licorice root products.
Children and teenagers should not use concentrated herbal supplements without appropriate guidance from a parent or guardian and a qualified healthcare professional.
If unusual symptoms develop after using a concentrated licorice root product, stop using the product and seek appropriate medical advice.
7. Harvest & Store Licorice Root
The root of the licorice plant is the primary part traditionally harvested for herbal use. Licorice is a perennial plant, and its underground roots and rhizomes develop over time.
Commercial licorice root is generally harvested, cleaned, dried, and processed before being sold as whole root, cut root, powder, tea, or extract.
If growing licorice at home, the plant should be well established before harvesting. After harvesting, the roots should be cleaned thoroughly and dried properly to reduce moisture and prevent spoilage.
How to Store Licorice Root
To maintain the quality of dried licorice root:
- Store it in a cool, dry place.
- Use an airtight container.
- Keep it away from moisture.
- Protect it from direct sunlight.
- Label the container with the herb name and storage date.
- Discard it if mold or unusual moisture develops.
Licorice root extracts, capsules, and other commercial products should be stored according to the manufacturer’s instructions.
8. Conclusion
Licorice root is a traditional herbal ingredient with a long history of use in teas, herbal formulas, throat preparations, food products, and topical applications. Its roots contain glycyrrhizin and other plant compounds that have been studied for different potential effects.
While traditional licorice root benefits include digestive, respiratory, throat, and skin-related uses, scientific evidence remains limited for many claims.
The most important consideration is safety. Regular or excessive consumption of glycyrrhizin-containing licorice root can affect blood pressure, potassium, and fluid balance. Choosing the right product and using concentrated forms carefully can help reduce unnecessary risks.
