Most people know licorice as a well loved dessert. It actually gets its flavor from a component in licorice root called Glycyrrhizin, which is much sweeter than sugar and what gives it its unique taste. Licorice root can also be used make medicine. It’s most known use is to treat various symptoms of digestive disorders, the most common of which are heartburn, chronic gastritis, stomach ulcers, and colic.

For centuries, licorice root has also been used to treat coughs and other ailments affecting the respiratory tract. It is usually made into tea to relieve itchiness of the throat and upper chest.I t acts as a demulcent, which means it coats the throat with a very thin lining of mucous. It is also an expectorant and clears congestion in the lungs and bronchial tubes to loosen phlegm so that it’s easier to cough up. Recent studies have discovered that licorice root has a component, known as¬†carbenoxolone, that may help keep mental skills sharp. Carbenoxolone stops an enzyme in the brain from making stress related hormones. These stress related hormones have been linked to age related mental decline, such as Alzheimer’s. A small study has shown that taking supplements daily improves verbal fluency in healthy elderly men, and even improves verbal memory in older adults that have diabetes. Researchers say that licorice root may be able to help and prevent decline in memory and cognitive skills due to aging.

Licorice comes in many forms. 1-5g of dried licorice root can be boiled into tea and taken 3 times a day, and the root can even just be chewed. In liquid form and as a component to other products, the dosage is 1mL 3 times a day for an upset stomach.
