The root of Glycyrrhiza glabra, better known as licorice, has many purported uses. Scientific evidence is insufficient to verify whether it actually helps any health conditions, according to MedlinePlus, a website affiliated with the U.S. National Institutes of Health. Licorice with the component glycyrrhizin can cause serious side effects, but deglycyrrhizinated licorice, called DGL, appears to be safe. Consult a qualified health care provider before taking Glycyrrhiza glabra.
Respiratory Benefits
Ayurveda, the traditional medicinal system of India, considers Glycyrrhiza glabra to be a tonic, expectorant and a demulcent, notes the Memorial Sloan-Kettering Cancer Center. A demulcent has soothing, coating properties, while an expectorant eliminates phlegm and mucous from the respiratory tract. These properties account for the traditional use of licorice as a cough reliever and an asthma treatment. Results in studies have been mixed, according to the University of Maryland Medical Center.
Ulcer Treatment
DGL may be beneficial for treating stomach ulcers. A small number of studies indicate that DGL combined with antacids had results comparable to prescription drugs, according to the University of Maryland Medical Center. One study found a high rate of success with licorice root fluid extract for treating stomach ulcers, but other studies had conflicting results. Animal research suggests DGL may protect against ulcers caused by aspirin use.
