Objectives : The purpose of this study is to discuss ginseng properties by historical research. Methods : Historical documentary records of ginseng were used to develop this review. Results : According to the historical research, the first Korean ginseng cultivation started from the Koryo Dynasty around A.D. 1000. Later, during the Chosun Dynasty around A.D. 1500$sim$1600, the ginseng cultivators established a method of cultivation. Gasam (cultivated ginseng) was cultivated ginseng on the skirts of their domicile. It was reported that Gasam cultivation was broadened throughout the country around A.D. 1790 on Cheongjosilrok. On the other hand, ginseng properties were reported slightly cool in the oriental herbal medicine books from A.D. 250 to A.D. 1600. But, they were reported slightly warm or warm after A.D. 1600. Korean ginseng cultivation started in the Koryo Dynasty around A.D. 1000. Later, during the Chosun Dynasty, the ginseng cultivators established a standard method of cultivation. Gasam, cultivated ginseng, was grown on the outskirts of their domicile. It was reported that Gasam cultivation was broadened throughout the country around 1790 A.D. in Cheongjosilrok. On the other hand, ginseng properties were reported slightly cool in the oriental herbal medicine books from 250 to A.D. 1600, but they were reported slightly warm or warm after A.D. 1600. Conclusions : It suggests that ginseng properties (slightly cool) before A.D. 1600 are wild ginseng. Also, wood-grown ginseng and ginseng properties (slightly warm, warm) after A.D. 1600 are Gasams.
