The authentication of Sokdan, one of the Korean traditional medicines, was performed with comparative study of morphological feature between Dipsaci Radix, roots of Dipsacus asper Wall. ex C.B. Clarke, and Phlomidis Radix, those of Phlomis umbrosa Turcz. In addition to a sensory observation, a stereoscope was used for more improve the accuracies. The surface of Dipsaci Rdix (DR) had more deeper furrows than it of Phlomidis Radix (PR). And more, the surface patterns of PR were more regular and fine than those of DR. In a section, DR did not have a clear distinction between nearby xylem, but PR did. In a distal section of DR, the color of cortex was dark-brown or dark- green and xylem was lemon yellow. On the other hand, PR was generally lemon yellow. It was discriminable for two herbs by observing pattern of furrows and colors of section.
