Licorice root has a sweet taste quite similar to star anise. The licorice root has long been known for its many beneficial uses because of its active compound known as glycyrrhizin, according to the University of Maryland Medical Center. It is recommended by many herbalists and holistic practitioners as an alternative remedy for various health problems and for boosting the adrenal health. In traditional medicine, licorice root is used for rheumatoid arthritis, scleroderma, lupus, and allergies. It is also known to be effective for peptic ulcer and mouth ulcers.

Licorice Root: From Candy To Herbal Medicine

Active ingredient and brief overview: The main active component in licorice root is glycyrrhizic acid, an anti-viral. In a 2009 study published in “Hepatology Research,” researchers at Tokyo’s Medical and Dental University state that this compound suppresses the replication of the hepatitis C virus.  In recent studies, glycyrrhizic acid has also been tested to disrupt the latent Kaposi sarcoma, a tumor caused by the Human herpesvirus 8 (HHV8).


  • Adrenal fatigue: The adrenal gland is responsible for hormonal release, in particular, the stress regulating hormone cortisol. A 1990 study published in “the Journal of Clinical Endocrinology and Metabolism found that glycyrrhizic acid blocks the enzyme that converts cortisol to cortisone, resulting in higher levels of cortisol. Cortisol is known to have a great effect in boosting a person’s energy and endurance level, stimulates the conversion of protein to carbohydrate and suppresses inflammation.
  • Anti-bacterial: Licorice root has anti-bacterial and anti-fungal properties.  Licorice root can be used to treat skin problems caused by the build-up of bacteria or fungus on the skin such as athlete’s foot, dandruff, acne, and other skin problems.
  • Cough relief: Licorice root can be used as an expectorant and cough remedy. Drinking licorice root tea thrice daily can help cure cough, asthma, and congestion. Licorice root has anti-inflammatory properties that will help loosen and release mucus and makes the air passages wider so that oxygen can flow more freely. It also has a soothing effect to calm lungs.
  • Laxative: Licorice root is good for the gastrointestinal tract. Licorice root can act as a laxative to help people with constipation. People with hemorrhoids can also benefit from this property of licorice root. Licorice can help in passing the bowels easier to avoid irritation and bleeding of the hemorrhoid glands.

In recent clinical studies, licorice root has been found to have anti-inflammatory and demulcent agents that can reduce the symptoms of eczema and other skin disorders. Topical application of licorice root extract can help in treating psoriasis, rashes, dry skin, itchy skin, and other skin disorders. To prepare a licorice root salve, bring 2 tbsp. dried licorice root and 6 cups water to a boil. Cover the pan, reduce heat and simmer for about 40 minutes. You can add this liquid to a cold compress and apply to the skin irritation or pour it into a bath for soothing relief.
  • Arterial health: Studies show that licorice root can improve the bile flow. Bile acids are responsible for the metabolism of cholesterol in the body and in eliminating the excess cholesterol.

This can help people with asthma, bronchitis, and dry cough. The anti-inflammatory properties of licorice root can also widen the air passages wider, making breathing easier.
  • Gastric problems: The flavonoid and chalcones that are found in the licorice root are used to treat different varieties of gastric and intestinal problems. The two chemicals can help in easing the infection and the inflammation of the mucous lining and intestinal tract.
