Licorice Herb – Uses And Side Effects

Used medicinally since Roman times, licorice is still popular in Chinese herbal medicine. The “licorice candy” sold In the United States usually is flavored with anise oil and doesn’t actually contain licorice. Besides serving as a flavoring and sweetener for bitter drugs, licorice is an ingredient in some tobacco products, chewing gums, candies, beverages, toothpastes, and shampoos.

Most licorice remedies come from the roots of Glycyrrhiza glabra, a perennial low growing shrub native to the Mediterranean region. Spanish licorice is the most common variety, but G. glabra plants are widely cunivated in the United States, Russia, Spain, Turkey, Greece, India, naly, Iran, and Iraq.

The plants are graceful, with light, spreading, pinnate foliage, presenting an almost feathery appearance from a distance. The leaflets (like those of the False Acacia) hang down during the night on each side of the midrib, though they do not meet beneath it. From the axils of the leaves spring racemes or spikes of papilionaceous small pale-blue, violet, yellowish-white or purplish flowers, followed by small pods somewhat resembling a partly-grown peapod in form. In the type species glabra, the pods are smooth, hence the specific name; in others they are hairy or spiny.

The underground system, as in so many Leguminosae, is double, the one part consisting of a vertical or tap root, often with several branches penetrating to a depth of 3 or 4 feet, the other of horizontal rhizomes, or stolons, thrown off from the root below the surface of the ground, which attain a length of many feet. These runners are furnished with leafbuds and throw up stems in their second year. The perennial downward-running roots as well as the long horizontal stolons are equally preserved for use.

What the research shows

Researchers have studied licorice extensively as a treatment for peptic ulcers. They’ve found that it performs no better than established drugs, may cause more side effects, and can be poisonous if taken in large doses for a long time.

However, glycyrrhetic acid, a chemical made from the licorice plant, shows promise in enhancing the effects of steroid preparations applied to the skin.
