"Shan Yao" (山薬), which was first described in the "Shen-Nung-Pen Ts'ao" (神農本草) as "Shu Yu (薯), is a common Chinese drug obtained from the rhizophors of several kinds of Dioscorea. We have undertaken histological studies on the rhizophors of the Dioscorea spp. found in Formosa and Japan in order to verify the source of the various kinds of "Shan Yao" found on the drug market. From the results of these studies, we have found that: 1) The Chinese "Shan Yao" produced in Central-China at present is obtained from Dioscorea batatas DECAISNE, where as the typical Japanese drug "San Yaku" is obtained from D. japonica THUNBERG. 2) The recent Formosan "Shan Yao" is obtained from several kinds of Dioscorea found in Formosa, i. e., D. alata L., D. alata var. purpurea (ROXB.) M. POUCH, the so-called "Airingrod", D. doryophora HANCE and the so-called "Dalitco". However, the authors have found several imitations of the "Shan Yao" in Formosa which were obtained from the starchy underground portion of Ipomoea batatas (L.) POIR-Tainung No. 31 or No. 17 (Convolvulaceae), Xanthosoma sagitiifolium SCHOTT (Araceae) and Manihot utilissima POIIL (Euphorbiaceae).
