Chinese licorice, Gan-cao, Glycyrrhiza uralensis. In China, licorice is first mentioned in Shen Nong Ben Cao Jing (first century A.D.). It is used in Chinese prescriptions for coughs, sore throat, asthma, gastric and duodenal ulcers, and as a mediator of potentially toxic ingredients. Licorice is one of the better-studied herbs. Numerous pharmacological and clinical reports confirm its usefulness in treating ulcers and support its reputation as a cough suppressant and expectorant. Licorice may cause some individuals to experience water retention and hypertension due to sodium retention and potassium loss. Individuals with heart disease, liver disease or hypertension should avoid licorice.
