Introduction

Licorice is one of the most widely used herbs in the world. It has a strong presence in Chinese and Ayurvedic traditional medicine, and was used by the ancient Greeks and Egyptians. In fact, it’s been used in foods and medicines by virtually all peoples that have had access to it for the last several thousand years.

Licorice also has a long history in flavoring foods, and the scientific naming alludes to this. Glycirrhiza means “sweet root.” The sweet taste comes from a saponin, glycyrrhizin, which is said to be 50 times sweeter than sugar. No doubt, this is a key contributing factor to its use in candies and deserts.

Whether due to its widespread use as a medicinal herb, or as a side-effect of its use in the food industry, modern science eventually took notice of the herb and began conducting experiments. What they discovered confirmed many traditional uses and expanded on others. In the 1980s, licorice was used as a major anti-ulcer drug. In recent years, its antiviral properties have come more into focus.

Whether you use licorice as a food or a medicine, it has a lot to offer.

Medicinal Properties of Licorice

Licorice has a large number of useful medicinal properties. Interestingly, one of the most valued properties has to do with how it affects other herbs, rather than how it affects us.

Licorice is called the great harmonizer. It has a way of helping other herbs work together while minimizing side effects. Licorice has a strong synergistic effect with other herbs and is used more often in combination than alone.⁴⁵⁾Buhner, Stephen Harrod. Herbal Antivirals: Natural Remedies for Emerging and Resistant Viral Infections. Pownal, VT: Storey, 2013.⁴⁶⁾Forêt, Rosalee De La. “Licorice Monograph.” HerbMentor.

Licorice is also a broad-spectrum antiviral that works through a number of mechanisms. It directly inactivates some viruses, keeps others from multiplying, and prevents still others from entering your cells. It is effective against many viruses, including HIV, herpes, hepatitis, tuberculosis, SARS, influenza, viral respiratory infections, pneumonia, tuberculosis, retroviruses, viral encephalitis, and the common cold.⁴⁷⁾Zhou, Jun-Xian, Markus Braun, Pille Wetterauer, Bernhard Wetterauer, and Michael Wink. “Antioxidant, Cytotoxic, and Antimicrobial Activities of Glycyrrhiza Glabra L., Paeonia Lactiflora Pall., and Eriobotrya Japonica (Thunb.) Lindl. Extracts.” Medicines 6, no. 2 (2019): 43. doi:10.3390/medicines6020043.⁴⁸⁾Buhner, Stephen Harrod. Herbal Antivirals: Natural Remedies for Emerging and Resistant Viral Infections. Pownal, VT: Storey, 2013.⁴⁹⁾Bone, Kerry, and Simon Mills. Principles and Practice of Phytotherapy Modern Herbal Medicine. Edinburgh: Churchill Livingstone, Elsevier, 2013.⁵⁰⁾Hoffmann, David. Medical Herbalism: The Science and Practice of Herbal Medicine.

Accessed April 12, 2019. https://herbmentor.learningherbs.com/herb/licorice/.

The main antiviral component in licorice is glycyrrhizin. All species of licorice contain glycyrrhizin in varying quantities, and can be used medicinally.⁵³⁾Buhner, Stephen Harrod. Herbal Antivirals: Natural Remedies for Emerging and Resistant Viral Infections. Pownal, VT: Storey, 2013. Cultivated licorice (Glycyrrhizi glabra) contains the highest concentration of glycyrrhizin, however Chinese licorice (Glycyrrhizi uralensis) is also commonly used. American licorice (Glycyrrhzi lepadita) has a lower amount of glycyrrhizin, though it is still favored by many.

Glycyrrhizin takes 4-8 hours to reach its maximum levels in the body, after being ingested. It then remains in the body for 72 hours, though most is removed after 24 hours. In short, glycyrrhizin is good at remaining in the body, helping it to keep working long after it is consumed.⁵⁴⁾Buhner, Stephen Harrod. Herbal Antivirals: Natural Remedies for Emerging and Resistant Viral Infections. Pownal, VT: Storey, 2013.

In the case of cold sores and other mouth ulcers, licorice can be applied directly in its powder form, or as a cream or salve.⁵⁵⁾Bone, Kerry, and Simon Mills. Principles and Practice of Phytotherapy Modern Herbal Medicine. Edinburgh: Churchill Livingstone, Elsevier, 2013. It can be used in the care of teeth and gums to prevent bacterial actions and the formation of biofilm.⁵⁶⁾Buhner, Stephen Harrod. Herbal Antivirals: Natural Remedies for Emerging and Resistant Viral Infections. Pownal, VT: Storey, 2013. For internal infections, it can be taken through a number of applications, as listed below. Licorice is also antibacterial and has immune-stimulating properties.⁵⁷⁾Zhou, Jun-Xian, Markus Braun, Pille Wetterauer, Bernhard Wetterauer, and Michael Wink. “Antioxidant, Cytotoxic, and Antimicrobial Activities of Glycyrrhiza Glabra L., Paeonia Lactiflora Pall., and Eriobotrya Japonica (Thunb.)

Truly, licorice is a powerful herb with a number of different, useful effects.

Nutritional Properties of Licorice

Licorice is typically not consumed in high quantities. It is more often used as a sweet flavoring in foods, drinks, and herbal formulas. It is high in several nutrients, such as magnesium, silicon, sodium, niacin, iron, and chromium.

Preparation and Usage 

The roots, stolons, and rhizomes are the commonly used parts for medicine-making. Leaves can also be used, but are less potent.

Synergize

Licorice is most often used in conjunction with other herbs, due to its synergizing and harmonizing effect. Your options abound in this regard, though one good option is to combine it with Chinese skullcap (Scutellaria baicalensis). Both are broad-spectrum antivirals and help to amplify each other’s effects.⁹⁵⁾Buhner, Stephen Harrod. Herbal Antivirals: Natural Remedies for Emerging and Resistant Viral Infections.

Softened Licorice Root Slices

While not lollipops in the traditional sense, these sweet, softened licorice roots can be sucked on by children (or adults) with a hoarse throat. Give one once each day to be sucked on for as long as desired. The hoarse throat usually disappears after 2 days.

• (1) 5-inch-long piece of licorice root
• 1 cup water
• 2 tablespoons honey (Omit if using Chinese or cultivated licorice.)

Put all the ingredients in a covered pot and bring to a boil. Reduce heat and simmer for 5 minutes. Strain out the pieces and set them aside. You can keep and drink the liquid, if desired. When cool enough to handle, root pieces can be given to children to suck on.

Tincture 

Place dried licorice root in a 40-50% alcohol solution, at a ration of 1 part root to 5 parts alcohol. You my want to add a bit of vinegar to the mixture. Gycyrrhizin is better extracted in a lower-pH environment.

Decoction 

Add 6 grams of powdered licorice root to 16 ounces (or 500 ml) of water and bring it to a moderate boil. Allow it to boil, uncovered, until the liquid volume reduces by half. Then add enough enough water to bring the volume up to 1,000 ml. Drink this throughout the day.

Powder 

Licorice powder can be used externally or internally. Externally, you can gently rub the powder onto canker sores and wounds to soothe them and help fight infection. Internally, the powder can be used in teas, in decoctions, or via any of the others methods listed.

Capsules

Divide 4,000 mg into three daily doses. One-half teaspoon of licorice powder is roughly 2,000 mg.

If you are concerned about taking too much licorice internally, you can still soothe a sore throat and fight microbes in the mouth by using licorice in a mouthwash. Add 1/2 teaspoon of licorice tincture to 1/4 cup water. Swish and gargle with this combination up to 4 times a day.

The whole root can also be fashioned into a toothbrush or into a tooth-cleaning stick.

To make a toothbrush, cut away the outer skin on the tip of the root and chew the inner fibers until they spread out like the bristles on a toothbrush. To refresh your toothbrush for future brushings, you can clip the chewed end of the root off and whittle away the outer skin on the next section.

To make a cleaning stick, use a knife to carve a wedge shape and use it to carefully scrape each tooth clean. Use your knife to continue modifying the edge to clean all the tooth surfaces. For detailed instructions on using sticks to clean your teeth, check out “Alternatives to Dentists.”

Precautions and Contraindications

Licorice is generally nontoxic, even in higher doses. However, long-term use is not recommended. Do not use licorice for more than 4-6 weeks without guidance from a medical professional. Blood pressure, potassium levels, and sodium levels should be monitored with extended use.

Lower doses may be safe over a longer time period, but even licorice tea can occasionally cause issues when taken for a period of years.⁹⁶⁾Buhner, Stephen Harrod. Herbal Antivirals: Natural Remedies for Emerging and Resistant Viral Infections. Pownal, VT: Storey, 2013.

Long-term use can cause hypokalemia (potassium depletion), headache, fatigue, dizziness, hypertension, weak limbs, edema, spastic numbness, and potentially heart attack. Very high doses can cause a decrease in body weight, thymus weight, and blood cell count. Symptoms abate after licorice use is discontinued.

Most side effects are linked to the glycyrrhizine in the licorice. Deglycyrrhizinated licorice products can be purchased. These products retain the soothing, demulcent properties of licorice, but lose many of their other properties.

Another way to minimize some side effects is to consume a low-sodium, high-potassium diet while taking licorice.

While licorice can be used with children and the elderly, this should be done with due caution.

Large doses should not be used with children. As children usually enjoy the flavor of licorice, you should monitor their intake.

Large and long-term doses are detrimental during pregnancy. Lower doses, such as might be used in a mouthwash, an occasional tea, or combined in low amounts with other herbs, appear to be safe.⁹⁷⁾Buhner, Stephen Harrod. Herbal Antivirals: Natural Remedies for Emerging and Resistant Viral Infections. Pownal, VT: Storey, 2013. High doses during lactation should also be avoided. Licorice is contraindicated in cases of hypertension, hypokalemia, hypernatremia, and low testosterone levels. However, low doses in combination with other herbs, over a period of no more than 10 days, should be fairly safe.

Licorice has an estrogenic effect. It can cause breast growth in men. This is especially true if used in high quantities for long periods of time, or with other estrogenic herbs. Like other side effects, this effect will go away after you stop taking the herb.

There is also anecdotal evidence that licorice’s estrogenic effect can impact a woman’s menstrual cycle, potentially lengthening it or causing spotting between cycles.

Due to the highly synergistic nature of licorice, it is not advised to take licorice with estrogenic pharmaceuticals, hypertensive drugs, cardiac glycosides, or diuretics.

How to Identify Licorice

This perennial plant grows up to 6 feet (2 meters) tall and 3 feet (a meter) wide. As a member of the pea family, licorice has several pea-like features. It’s leaves are pinnately compound, 3-6 inches long with 9-17 oval leaflets. The flowers grow in dense racemes and have the typical banner, wings, and keel of a pea family bloom. They can be blue to purple, or yellow with other species.

The roots grow up to 4 inches across and descend as deep as 3 feet (1 meter). Rhizomes spread out from the roots and can emerge as much as 26 feet (8 meters) away from the parent.

The inside of the roots is usually yellowish, with wild species being darker.

Several members of the pea family might be considered look-alikes for this plant. Goats rue (Galega officinalis) is possibly the closest. If you are unsure, these two can be differentiated by the stem. Licorice has a solid stem, while goats rue has a hollow one. Licorice also has a burr-like seed pod, which helps to differentiate it from other pea family members.

Where It Grows and Where to Find It

Cultivated licorice (Glycyrrhiza glabra) can be found in cultivation, and escaped, in much of the world. Chinese licorice (Glycyrrhiza uralensis) grows wild in southeastern Europe and southwestern Asia. American licorice (Glycyrrhiza lepidota) can be found throughout most of the United States and Canada. You can find some species of licorice nearly everywhere.

Licorice is adapted to many environments, but can often be found along waterways in sandy soil. Many members of the genus prefer wet climates, but others vary and can even be found in semiarid deserts. Representatives of the genus can be found from sea level up to 8,500 feet (2.500 meters).

How and When to Harvest

The roots are typically harvested in autumn, when the concentration of glycyrrhizin is greatest. 3- to 4-year-old roots are preferred, as larger roots have a higher concentration of glycyrrhizin. With Glycyrrhiza uralensis, wait for at least 4-year-old roots, and harvest in mid-summer.

Established licorice plants have a lot of root mass. The amount you can harvest will depend on the age of the plant and how deeply you dig.

A well-established plant could provide a family with medicine indefinitely. It is doubtful that you would ever completely dig out the root system, which would keep the plant coming back year after year.

However, spreading out your harvest between plants, with a few years to recover in between, is kinder to the plant.

Licorice can be propagated by root cuttings, allowing you to bring wild plants closer to your home. Once established, they are very hardy and even difficult to get rid of. So think carefully about where to put them. Licorice can also be grown from seed, though this is less reliable.

Licorice is a great-tasting medicine with tons of applications. Whether you use it as a medicine or a flavoring, it has a lot to offer.
