Licorice helps fight many digestive disorders such as heartburn. Recommended by naturopaths, licorice helps in the formation of mucus that lines the wall of the stomach and protects it against gastric juices. In case of gastroesophageal reflux, it is advisable to take 2 to 5g of dried licorice roots 3 times a day in the form of powder, infusion or decoction (= roots boiled directly in water).
