| Remarks | At present, three species of Daji (= Taigeki) are distributed in China, Kōgataigeki of family Rubiaceae, Sōtaigeki of family Leguminosae and Kyōtaigeki of family Euphorbiaceae. Though each plant belongs to a different family, they are all called Taigeki. By nature, the real Taigeki described in materia medicas is Kyōtaigeki. However, only Kōgataigeki is imported to Japan in the present day. Kōgataigeki: the root of Knoxia valerianoides Thorel ex Pitard of family Rubiaceae. Sōtaigeki: the root bark of Lespedeza formosa (Vog.) Koehne of family Leguminosae or L. davidii Franch. In Xinjiang Uigur Autonomous Region, the root of Euphorbia soongarica Boiss. is used as Taigeki. Wataigeki, produced in Japan, is the root of E. pekinensis Rupr. var. japonensis Makino (Jap. name: Takatōdai, Ibukidaigeki). The root is cut vertically and dried, however it is not available in the market now. Korean Taigeki is the root of E. sieboldiana Morr. et Decne. (Jap. name: Natsutōdai). | ||||||
