Licorice Root has long been known for its ability to soothe respiratory inflammation. Licorice Extract is a proven treatment for stomach ulcers. The extract also seems to have a beneficial effect on viral infections of the liver.

Licorice contains glycyrrhetic acid, which helps heal stomach ulcers. Other ingredients including glabridin, glycyrrhizin and licoricidin soothe inflammation. The glycyrrhizin in Licorice also appears to combat viruses such as hepatitis B, influenza and HIV by boosting the immune system's T-cell count and stimulating production of protective compounds such as interferon.
