Licorice is an herb that is native to the Mediterranean, southern and central Russia, and Asia Minor to Iran. Many species are now grown throughout Europe, Asia, and the Middle East. Licorice contains glycyrrhizic acid, which can cause complications when eaten in large quantities. Many "licorice" products manufactured in the U.S. actually don't contain any licorice. Instead, they contain anise oil, which has the characteristic smell and taste of "black licorice."
Licorice is taken by mouth for various digestive system complaints including stomach ulcers, heartburn, colic, and ongoing inflammation of the lining of the stomach (chronic gastritis).
Some people take licorice by mouth for sore throat, bronchitis, cough, and infections caused by bacteria or viruses.
Licorice is also taken by mouth for Addison's disease, a type of diabetes caused by a hormone deficiency (diabetes insipidus), menopausal symptoms, osteoporosis, osteoarthritis, systemic lupus erythematosus (SLE), liver disorders, malaria, tuberculosis, high potassium levels in the blood, food poisoning, chronic fatigue syndrome (CFS), a condition in which there is too much muscle tone (hypertonia), abscesses, recovery after surgery, rash, high cholesterol.
