Licorice root is one of the most widely used medicinal herbs worldwide and is the single most used herb in Chinese medicine today. It was used by the Egyptians as a flavoring for a drink called Mai-sus, and large quantities were found in the tomb of King Tut for his trip into the afterlife. Pliny the Elder recommended it to clear the voice and alleviate thirst and hunger. Dioscides, when traveling with Alexander the Great, recommended that his troops carry and use licorice to help with stamina for long marches, as well as for thirst in areas of drought. In the Middle Ages it was taken to alleviate the negative effects of highly spicy or overcooked food.
Chew on the stick or brew it in a pot of tea. You can also add it to cold beverages to give them a subtle sweet flavour.
