Objectives : This study aimed to review the change in the origin of Sokdan(續斷) by diachronically analyzing literature data from Korea and China. Methods : Literature records describing the origin(synonyms, location of production, description) of Sokdan were collected, records were divided into periods. The main contents were included in the results, and original texts were edited and summarized in the table. Results : Sokdan, whose leaves resemble Jeoma(苧麻)(SJ), was first recorded in 《Xinxiubencao(新修本草)》, and described in detail in 《Bencaotujing(本草圖經)》 during the Tang and Song dynasties in China. In modern times, SJ was assumed to be genus Phlomoides or Lamium; however, records of the plant have decreased. Finally, SJ was not included in the 《Pharmacopoeia of the People's Republic of China》 as Sokdan. However, 《Diannanbencao(滇南本草)》, 《Diannanbencaotushuo(滇南本草圖說)》, 《Zhiwumingshitukao(植物名實圖考)》 described Sokdan of dian(滇). It was assumed genus Dipsacus. From the 1950s onwards, Sokdan is described in the literature as a member of the genus Dipsacus. In korea, SJ was recorded in 《Hyangyakjipseongbang(鄕藥集成方)》 and 《Dongeuibogam(東醫寶鑑)》 during the Joseon dynasty. In modern times, the genera Phlomoides and Lamium were mostly recorded as the origin of Sokdan. Conclusions : Several species have been described as Sokdan over the years in China, but since the 1950s, the genus Dipsacus was noted as the origin of Sokdan. In Korea, SJ was used in the past, thus Sokdan was recorded as P. umbrosa in 《The Korean Herbal Pharmacopoeia(KHP)·1985》. However, 《KHP·1998》 referred to P. umbrosa as Hansokdan and D. asperoides as Sokdan.

Objectives : The roots of Dipsacus asper had been used as the herbal medicine "Cheon-Sokdan" in Korea. Moreover, the roots of Phlomoides umbrosa were used as "Han-Sokdan." In the present study, a comparative anatomical comparison of Cheon-Sokdan, Han-Sokdan, and Ilbon-Sokdan were conducted, because Ilbon-Sokdan, the roots of Dipsacus japonicus, was regarded as substitute of Cheon-Sokdan. Methods : For this study, permanent preparations were made using a paraffin embedding method. Anatomical features of these three Sokdans were observed using a light microscope. Results : The starch grains of parenchyma cells and the amounts of calcium oxalate crystals hardly differed among the three plants. Particularly, the longitudinally-sectioned vessels of the three plants showed a wide variety depending on the focal depth of the light microscope. Therefore, these features could not be considered as obligate criteria for distinguishing these plants. The shape of the xylem was linear in Cheon-Sokdan and Ilbon-Sokdan, whereas that in Han-Sokdan was wedge-shaped. The phloem of Cheon-Sokdan and Ilbon-Sokdan were rhomboid, whereas that of Han-Sokdan was thimble-like. Therefore, the shape of xylem and phloem appeared as good criteria for distinguishing Han-Sokdan from the other plants studied. Cheon-Sokdan and Ilbon-Sokdan showed characteristics similar in many parts. However, in the xylem of Ilbon-Sokdan, fiber bundles were more developed than those of Cheon-Sokdan. Therefore, the development of fiber bundles in xylem was considered suitable for distinguishing between Cheon-Sokdan and Ilbon-Sokdan. Conclusions : The identification-keys established in this study would be helpful for identifying microscopic features among the three Sokdans.
