Licorice Root Uses, Benefits, and Safety

Licorice root, also called “sweet root,” is a centuries-old food and medicinal herb. Both Eastern and Western medicine utilize licorice root as a treatment for conditions ranging from anxiety to the common cold to liver diseases. And while you might enjoy the taste of licorice in black bits or strips, many licorice-flavored candies sold in the United States contain anise oil rather than actual licorice root. Anise oil has a licorice-like flavor but is derived from the Pimpinella Anisum plant; it contains no licorice root.

Licorice for Eczema

Topical forms of licorice root have been studied for eczema, a chronic inflammatory skin condition that affects people of all ages. By soothing irritated skin, products containing licorice help reduce redness, swelling, and itchy skin that occurs with eczema outbreaks. Learn more tips in our Healthy Skin article.

Licorice Root for Anxiety

Licorice root has a long history of use in traditional herbal practices, including formulas intended to support the body’s response to stress. However, there is insufficient clinical evidence to establish licorice root as a treatment for anxiety. The University of Maryland Medical Center says some people use licorice root to treat anxiety.

Because licorice can affect blood pressure, potassium levels, and certain medications, consult a qualified healthcare professional before using it regularly. It is always best to follow a healthy lifestyle.

Other Uses for Licorice

The National Center for Complementary and Alternative Medicine lists licorice as a potential use for managing symptoms of bronchitis, sore throat, infections, and viral infections. Licorice root has traditionally been used in herbal preparations for coughs, sore throats, and respiratory support. Its compounds have also been investigated for antimicrobial and anti-inflammatory properties, although research has not established licorice as a treatment for infections or viral illnesses.

Safety and Cautions

Licorice contains glycyrrhizin, which can raise blood pressure, lower potassium levels, and cause irregular heart rhythms, particularly with excessive or prolonged use. DGL has most of this compound removed. Licorice root is available in various forms, including teas, capsules, and topical applications. People who use certain medications, such as diuretics, corticosteroids, and oral contraceptives, may be at risk for drug interactions. Additionally, licorice may not be safe for people with certain medical conditions, such as hypertension, heart disease, diabetes, kidney disease, or liver disease. Also avoid during pregnancy.
