History of Licorice
Licorice is a shrub that grows in subtropical climates. It has been used medicinally for more than 3000 years, and is often called "The Grandfather of the Herbs".


It was used to treat a variety of complaints including congestion, coughs, colds, rashes, constipation and arthritis. It was also used to treat more serious problems like cancer and hepatitis.


The Chinese call it "the great detoxifier" as it is thought to rid the body of poisons. Native Americans made a tea from licorice, drank it as a laxative, and used it to treat earaches and coughs.
