What is Licorice Root?

Updated on May 28, 2014

What is Licorice? Candy or Healing Herb?

The first time I heard that liquorice (also spelled licorice) could be used to heal different ailments, I laughed. I mean, how the heck was candy supposed to cure depression or heal ulcers? It took me a while to realize there was actually a licorice plant and not just licorice candy.

Since that realization, I've been astounded by the proven health benefits of licorice root. I mean, a lot of herbs are used for healing purposes, but most haven't been proven to work. But it's different with licorice root. Because it's one of the most widely used herbs in the world, many of the healing benefits of licorice root have been documented and proven to work. There have been almost 200 clinical trials testing what it can and can't do. And with each positive result, the powers of licorice become that much stronger.

Unlike a lot of herbs, licorice isn't thought of as a wanna-be healer. It's been proven so many times, it's making some doctors reach farther than ever. Did you know that it's been tested on both cancer and HIV? And both studies showed positive results. The polyphenols in licorice induce cell death in the cancer cells and it does this without harming anything else. Two recent studies about the effect of licorice on HIV found that the antiviral properties of glycyrrhizin and glycyrrhetinic acid can prevent the virus from entering healthy cells and replicating itself. In both studies, not a single person using licorice root developed Aids. Unfortunately, the placebo groups weren't so lucky.

Prevent the Bad Effects of Licorice by using DGL

Whole licorice contains a compound called glycyrrhizin. While it provides numerous health benefits, ingesting too much of it can cause fluid retention, increased blood pressure, loss of potassium and other harmful side effects.

These effects can be prevented by using deglycyrrhizinated licorice (DGL), which is licorice root with the glycyrrhizin removed.

Licorice Tea

Drinking licorice root tea everyday can have amazing effects on your health. It's been proven to treat multiple digestive problems like ulcers, acid reflux, heartburn, constipation and indigestion. And while it's doing all that, licorice root tea can also strengthen your immune system by boosting your body's levels of interferon (a substance that attacks viruses). But the health benefits of licorice root don't stop there. Licorice also contains at least 8 different compounds that help relieve the symptoms of depression.

Just think about it. A healthy body and a sound mind could be yours by drinking just 2 - 3 cups a day.

This caffeine free tea is made of pure licorice root. The recommended dose is 3 cups a day for 2-4 weeks. Then break for 2 weeks.


Licorice Extract

Licorice contains plant estrogen very similar to those found in soy. By binding tightly to estrogen receptors, this gives licorice an effect almost like real estrogen, which makes it the perfect natural remedy to treat the symptoms of menopause.

By encouraging the production of your estrogen and stimulating your adrenal gland, you're overworked kidneys and adrenal gland will get a break. This will help with the frequent trips to the bathroom. Drinking 1 - 2 cups of licorice tea or taking 30 drops of licorice extract everyday could help curb your hot flashes.

While it helps stimulate the production of estrogen in women, it does the exact opposite in men. An article in The New England Journal of Medicine stated that the glycyrrhizic acid in licorice can sometimes inhibit 2 of the enzymes needed to convert androstenedione to testosterone. If this happens, a mans testosterone level will decrease and that could leave him with a decreased sex drive or hypertension. The good news is that everything will go back to normal once he stops using licorice.

Licorice extract is a great herbal remedy to keep on hand. This specific extract was prepared from the roots of hand harvested organically grown licorice. It was extracted using a 1 : 2 ratio with organic grain alcohol and distilled water.

If you don't like the taste of licorice, you'll be happy to know that licorice extract (or glycyrrhiza) tastes nothing like licorice. Glycyrrhiza is said to be 50 times sweeter than sugar and that gives it a yummy taste of it's own.


Licorice Root

Licorice Benefits
Licorice Benefits

Licorice root is one of the most effective natural treatments available for healing a variety of ailments in the mouth. These include canker sores, gingivitis, tooth decay, and other mouth sores. There are three popular ways to treat sores inside the mouth:

The first is a dissolving licorice patch like CankerMelts. The active ingredient in CankerMelts is glycyrrhiza (licorice extract). By placing the disc on or near a canker sore, you'll begin to feel relief almost immediately. And as it slowly dissolves, it will relieve the inflammation around the sore. As an alternative, you can easily make your own licorice lozenges.

The second way is by making your own licorice mouthwash or licorice infusion. For mouthwash, just combine a 1/2 teaspoon of licorice extract with 1/4 cup of water. Gargle thoroughly and then spit it out. Use this mouthwash up to 4 times a day.

The third way is by using licorice tablets. Some people just chew them slowly, while others use the tablets to make a paste. That's easily done by crushing a licorice extract tablet into powder and adding water to make a paste. Then spread it on the affected area up to 4 times a day.

These licorice root chewable tablets are deglycyrrhizinated to make them safer for you. These are perfect for those who don't like the taste of licorice (like me) because they're mocha flavored. But just because they're chewable tablets, doesn't mean you have to chew them. As stated above, you can grind them up and make a paste or you can grind them up and add with water to make a mouthwash.


Licorice for Skin

Licorice is a very effective treatment against certain skin ailments like eczema and rosacea. It's most effective when applied topically using a 2% gel. It's also a great weapon against wrinkles and uneven skin tone. The key ingredient is a flavonoid called glagridin. This compound is what inhibits pigmentation and encourages even skin tone. What's great about licorice is that it's not a skin bleacher. It's actually a skin brightener. So if you have age spots, you don't have to worry about carefully applying it just to those dark spots. You can rub the licorice lotion or gel all over your face and with time, it will lighten the dark spots and brighten your normal skin. After a month or so, you should have a nice even skin tone again that's smoother than ever. It works the exact same way to fight against eczema and acne.

Often you'll find beauty products containing both licorice and chamomile. This is because chamomile contains a special compound that promotes healing and encourages tissue regeneration. When you add that to the powers of glagridin, these two herbs are just about unstoppable.


Licorice with Glycyrrhizin

Licorice with glycyrrhizin can be used safely if taken in small doses (no more than 500 mg a day) and by using for no more than two weeks at a time. Glycyrrhizin is actually the strongest therapeutic compound in licorice. Glycyrrhizin increases the production of mucus and relaxes bronchial spasms. Because of this, it's often used to treat bronchitis, sore throat, congestion, coughing and other respiratory illnesses. Glycyrrhizin enhances the production and activity of cortisol, which is an anti-inflammatory. Because of this, licorice root is often used to treat asthma and arthritis. The increased cortisol activity also increases energy levels, reduces stress and treats different ailments sensitive to cortisol levels, such as chronic fatigue syndrome and fibromylagia.

The anti-inflammatory properties of licorice can even be used in the treatment of hepatitis. It does this by fighting the virus that causes hepatitis and by supplying the liver with powerful antioxidants that help maintain it's health. Plus the anti-inflammatory properties help calm the liver inflammation associated with hepatitis.

Glycyrrhizin is also a very powerful weapon against the herpes simplex virus. It's been proven that by applying a paste or tincture directly to herpes lesions, glycyrrhizin acid irreversibly inactivates the virus. It's able to inhibit the growth of several viruses without affecting your own cell activity.

Nature's Way Licorice Root, 450mg, 100 Capsules


This is an extract of licorice in a base of vegetable glycerin. 1/2 a teaspoon will give you 150 mg of Glycyrrhizic acid. Using the suggested daily dose of 1/4 - 1/2 teaspoon 3 times a day will let you gain the health benefits of the glycyrrhizic while still keeping your risk of side effects to a minimum.


Dosage and Side Effects of Licorice Root

These doses are all for an adult weighing approximately 150 pounds. Adjust for weight as necessary.

  • Dried root: 1 - 5 g, 3 times daily

    Take as an infusion or decoction (boiled)

  • Tincture: 2 - 4 mL, 3 times daily
  • Extract: 250 - 500 mg, 3 times daily
  • DGL chewable tablets: 3 times daily

  1. Do not use licorice if you have:

    Heart failure

    Heart disease

    Fluid retention

    High blood pressure (hypertension)


    Kidney disease

    Liver disease

  2. Do not use licorice if you take any of the following medications:

    Ace inhibitors and diuretics

    MAO inhibitors




    Oral contraceptives

    Aspirin or other anti-inflammatory drugs

  3. Do not use licorice if you're pregnant or breastfeeding

    One study showed that glycyrrhetinic acid inhibits the compound responsible for protecting the fetus, causing the cortisol to gain direct access to the fetal circulation system. A later study showed that the high cortisol level caused low birth weight.

    A different study showed that when 9 pregnant rats were fed compounds from licorice, their babies were born with skeletal deformations.

    So please don't use licorice if you're pregnant or breastfeeding.

  4. Taking too much glycyrrhizin can cause many nasty side effects.

    Too much glycyrrhizin can cause pseudoaldosteronism, which then can cause fatigue, headaches, high blood pressure, and heart attacks.

    Too much glycyrrhizin can also cause hypokalemia, which is low levels of Potassium, increased fluid retention and high blood pressure. Many herbalists recommend supplementing your herbal licorice remedy with potassium supplements.

  5. Regulate your glycyrrhizin intake.

    No more than 500 mg a day. And every few weeks, stop using licorice completely . This will prevent toxicity.

  6. Do not drink grapefruit juice while taking licorice.

    Grapefruit juice enhances the effects of many medications, licorice included.

Proof that Licorice Root Heals

Licorice root is one of the few herbs that's been studied enough to prove that it actually does have healing properties. In fact, there's been at least 195 documented clinical trials done studying the different healing aspects of licorice and glycyrrhiza.

  1. Estrogen and Progestin Bioactivity of Herbs

    Documenting that licorice root contains plant estrogen similar to those found in soy, and that they bind strongly to estrogen receptors.

  2. Kinetics and dynamics of orally administered 18 beta-glycyrrhetinic acid in humans

    Documented that daily doses of 500 mg or less of glycyrrhizic acid decreased the risk of inhibiting (11 beta OHSD).

  3. Studies on the protective effect of deglycyrrhinised liquorice against aspirin (ASA) and ASA plus bile acid-induced gastric mucosal damage

    Documented that DGL Licorice is effective for treating ulcers.

  4. Identification of glycyrrhizin as a thrombin inhibitor

    Documented that glycyrrhizin owes part of it's anti-inflammatory properties to the inhibition of thrombin.

  5. Glycyrrhizic acid inhibits virus growth and inactivates virus particles

    Documented that glycyrrhizic acid attacks certain viruses and permanently inactivates herpes simplex virus particles.

  6. Effect of Glycyrrhiza glabra roots and glycyrrhizin on the glucuronidation in rats

  7. Activation of macrophages by crude polysaccharide fractions obtained from shoots of Glycyrrhiza glabra and hairy roots of Glycyrrhiza uralensis in vitro

    Documented that certain sugars in Licorice root stimulate the production of macrophages (immune cells).

  8. Inhibition of human complement by beta-glycyrrhetinic acid Immunology

    Documented that beta-glycyrrhetinic acid is an inhibitor of certain types of inflammatory immune system components.

  9. Deglycyrrhizinated liquorice in aphthous ulcers

    Documented that DGL mouthwash is effective in treating small ulcers in the mouth.

  10. Effect of deglycyrrhizinated liquorice on gastric mucosal damage by aspirin

    Documented that DGL is effective in reducing stomach bleeding caused by asprin.

Licorice Infusion
Licorice Infusion

Licorice Infusion

Although infusions are normally drunk the same as tea, a licorice infusion is different. Instead, it's meant to be used the same as a mouthwash.


  • 2 cups water
  • 1 Tbsp dried crushed licorice root


  1. 1. Heat the water until just boiling
  2. 2. Remove from heat, mix in the licorice root and set aside for 20 - 30 minutes
  3. 3. Strain the pulp out and discard
  4. 4. Let the infusion cool to room temperature and then store in a container with a lid
  5. 5. Use this infusion the same as you would use mouthwash, up to 4 times a day

Licorice Lotion

Applying licorice lotion to your skin everyday is an easy way to make sure your skin stays healthy and beautiful. If you suffer from uneven skin tone, acne, eczema, or some other skin condition, this lotion could be just what you need. Licorice contains this fantastic compound called glagridin. It's a flavonoid that inhibits pigmentation to encourage even skin tone. It's anti-inflammatory, anti-irritation properties will help soothe and clear up acne, eczema and rosacea.


  • 1 oz Beeswax
  • 1 oz Cocoa Butter
  • 3 oz Grapeseed Oil
  • 60 drops licorice essential oil


  1. 1. Melt the beeswax in a double boiler or a crock pot.
  2. 2. When it's melted, add the cocoa butter and grapeseed oil. Mix it completely.
  3. 3. When it's mixed together, remove it from heat and let it cool to room temperature.
  4. 4. When it's cool, add the licorice oil. Mix well, then pour into a sterile container with a lid.
  5. To keep your lotion fresh, store it in a dark colored container and seal it tight when it's not in use. Store it away from sunlight.

      I drink licorice tea daily for adrenal support. without it I become exhausted and can't get through the day. it helps your body reuse and recycles the cortisol that is in your body. Cortisol is your "get up and go" hormone. When you have adrenal fatigue you don't make enough cortisol, so using licorice makes your body re-use what little you have and this really helps!
