In China, the crude drug licorice (kanzo in Japanese, gancao in Chinese) has been used both dried and roasted as the situation demands from ancient times. The meaning of roasted licorice is simply roasted and honey-roasted in ancient and modern times, respectively. However, it is not clear medicinal purposes of processed licorice or why licorice processed with honey began to be used. We researched ancient literature and found that the main objective of roasting was to change the property of licorice from cool to warm (i.e., dried licorice had the effect of draining fire), while roasted licorice was used as an energy supplement, having a digestive effect and thus warming the body. Meanwhile, doctors began using honey-roasted licorice to treat throat pain from the Song dynasty, and then at the end of the Qing dynasty, honey-roasted licorice was expected to have the same effects of roasted licorice (i.e., supplementing energy and having a digestive effect).
