Korean ginseng is botanically identical to the ginseng plant growing in Manchuria and in the maritime province of Siberia. Historically, Korean ginseng plants grew abundantly in the forested mountains over the peninsula. Wild mountain ginseng is called san-sam. Korean ginseng has been a very valuable remedy in medicine since the sixth century. In modern times, Korea has become the major ginseng-producing country in the world. This may be ascribed to the fact that Korea has the longest history in producing ginseng. Moreover, the climate and geographical conditions may be optimal for ginseng cultivation. Korea deserves the title of the “ginseng country.”
