Licorice
Background: Natural licorice, which has a very sweet taste, is extracted from the root of a shrub and used medicinally. Most licorice candy made in the United States is artificially flavored and does not contain true licorice.
Medicinal Claims: Licorice is used to suppress coughs, to soothe a sore throat, and to relieve stomach upset. Applied externally, it is thought to soothe skin irritation (for example, eczema).
Possible Side Effects: Licorice may cause fluid retention. Frequently taking large amounts of licorice can result in high blood pressure (hypertension).
