Licorice Root Extract Uses

Licorice root comes from a flowering plant called Glycyrrhiza glabra that grows in Europe, Asia and the Middle East. It has been used as a medicinal herb for thousands of years. The herb is sold as powdered and cut root, is available in capsule and tablet form, and is used in tinctures, teas and topical gels. Licorice root has a number of culinary and medical applications.

Internal Remedies

Licorice has been traditionally used as a treatment for asthma and coughing. It was valued as an effective demulcent and expectorant, and was used to coat and soothe sore throats and help rid the body of mucus and phlegm. It is also a remedy for canker sores, indigestion and possibly for peptic ulcers. According to the University of Maryland Medical Center, one study found that licorice may also be useful in reducing body fat, but contributes to water retention.

External Applications

Licorice has been used as a traditional herbal remedy for eczema, cysts and itching, among other conditions. It contains a substance called glabridin that lessens inflammation. In cosmetic products, licorice treats acne and lessens sunburn damage. A 2003 study by Mazandaran University of Medical Sciences indicates that a gel containing a 1 percent or 2 percent licorice extract solution showed promise as a treatment for the itching and discomfort associated with atopic dermatitis. In addition, a licorice extract called liquiritin has demonstrated benefits in treating a dark skin discoloration called melasma.

Culinary Uses

Licorice root extract adds flavor to foods and drinks, such as root beer, fruit juices and syrups as well as some alcoholic beverages. Licorice is also used in candies, but to a small degree; most contain less than 2 percent licorice extract. Most of the flavoring in licorice candy comes from anise or synthetic substitutes. Licorice root also adds flavor to some brands of chewing gum, baked goods and medications.

Tobacco Industry

Licorice is most commonly used as a flavoring for tobacco products such as cigars, chewing and pipe tobacco. It decreases the harshness of nicotine and improves the smoothness and flavor of the tobacco. Licorice also improves the moisture quality and shelf life of tobacco products and ensures that the flavors are spread evenly through the tobacco. Licorice adds a sweet smell to the smoke and reduces mouth and throat dryness.
