This study was carried out to investigate histological characteristics of Korean ginseng in steaming process. The Korean red ginseng were prerared with 6-years-old ginseng according to the steaming prcess and dried with 13{pm}0.5% moisture and than cut in vertical section and horizontal section. The tissues are separated into epidermis, cortex, and xylem observed with Scanning Electron Microscope. The materials dried without steaming process contain cell membrane and crystallization of starch particle within them. But Korean red ginseng with prolonged steaming process are condensed, and the large hollows and cell membranes of vessel and resin duct are disappeared. In addition, Ca-oxalate rosette crystal is not found in the case of above 60-minute steaming time. The reason is that the tissues are condensed because of dry after elements’’ gelatinization.
