The Indigenization of Licorice and Its Meaning During the Early Days of the Joseon Dynasty / 의사학

This article explores the indigenization of licorice(Glycyrrhiza uralensis Fisch.) which was the most important medicine of the Oriental Medicine. There are a lot of records on licorice even before the Joseon Dynasty. The licorice had been used mainly in stomach related diseases such as food poisoning or indigestion. But the licorice was an imported medicine until the early days of the Joseon Dynasty. As the Joseon Dynasty began, the licorice production became necessary with the investigation and obtaining the herbs. And a large amount of licorice was needed when the epidemics outbroke under the reign of King Sejong. In particular, the licorice had been essential in treating the diseases of the Cold Damage which was focused in the Joseon Dynasty. That was why King Sejong ordered to plant the licorice in the Chollado province and Hamgildo province in 1448. But the licorice cultivation was not easy for two reasons. First, it was difficult to find the proper soil for proper soil for planting. Second, the people didn't actively grow the licorice, because they had to devote the licorice as the tax when the indigenization of licorice was succeeded. King Sejo and King Seongjong encouraged the people to plant the licorice. The recognition that the licorice is essential in pediatric diseases such as smallpox got stronger then before. Finally the indigenization of licorice was completed under the reign of King Seongjong. According to the Dongguknyeojiseungnam, edited in 1481, and Shinjeungdongguknyeojiseungnam, edited in 1530, the licorice was planted in seven districts. With the success of the indigenization of licorice, the approach of the people to the Oriental Medicine treatment had became much easier.

Physiological features and genetic polymorphism of a new breed licorice Wuxin No.1 / 中草药

Objective A new breed of licorice seeds(Wuxin No.1) was selected from wild licorice,Glycyrrhiza uralensis.Methods Its germination rate,content of soluble protein,and peroxidase(POD) activities were investigated and compared with the wild licorice seeds(control group).The leaves of Wuxin No.1 were collected and its genetic polymorphism was analyzed by inter-simple sequence repeat technique(ISSR).Results The results suggested that the seed vitality in Wuxin No.1 was higher than that in the control group.The change of soluble protein and POD activity also demonstrated that the seeds in Wuxin No.1 have the higher vigor.ISSR Analysis showed that among 22 random primers used in this experiment,six primers generated different DNA band types,which meant that there was genetic polymorphism in Wuxin No.1.Conclusion All these changes indicate that Wuxin No.1 is a prospective domestication species of licorice and may be cultivated widely in the future.
