A typical appearance of a stall selling "ginseng" root. At this stall one can buy this root in all possible forms, e.g. dried, raw, in a tincture, in flakes, in powder, etc. Notice that instead of the vendor in the photo you can see me (i.e. Prof. Dr. Eng. Jan Pajak). Such "ginseng" root stalls are plentiful in Korea.
