The history of Cao Ling:

Licorice has been used as medicine for a long time. As early as more than two thousand years ago, Shennong Herbal Classic listed it as a good medicine. Tao Hongjing, a medical scientist in the Southern Dynasties, respected licorice as "the old man of the country" and said: "This grass is the king of many medicines, and there are very few people who don't use it in ancient books." "the country is old", that is, the name of the empire.

The reason why Ural Glycyrrhiza uralensis Fisch is regarded as the "imperial doctor" of medicine is just as Li Shizhen explained in Compendium of Materia Medica: "Among all the medicines, Ural Glycyrrhiza uralensis Fisch is the king, treating 72 kinds of milk stone poisoning, solving 1,200 kinds of plant poisoning and reconciling various medicines, so it is called" the old country ".

According to the determination, the content of glycyrrhizic acid in licorice is about 10%, and there are many components such as mannitol and glucose. Because glycyrrhizic acid is 50 times sweeter than sucrose, licorice is really a "sweet grass".
