Many investigators reported the mineral corticoid hormon-like action of Glycyrrhizin. The other investigators suggested concerning the glucocorticoid hormon-like action. Authors had been observed the glycogen content of the liver to make sure the relationship between glucocorticoid like action of Glycyrrhizin and glucose metabolism in the liver. There was significant increase in the liver glycogen content in rat fed Glycyrrhizin for two weeks, however it was confirmed that Glucuronic acid combined with Glucuronic was unable to make any influence to glycogen content. The relation concerning the effect of Glycyrrhizin on liver glycogen and its mechanism of action might be needed followup study.
