Abstract Through studies on morphological characteristics, distribution and ecological habitat described in ancient literatures, Osmunda japonica is believed to the original plant of Chinese herbal medicine Cyrtomium Rhizome. Meanwhile, analysis is also made on causes for descriptions that do not comply with characteristics of O. japonica such as toxicity, flowers and fruits, illustrations, indumentums and flakes as well as appearance of other original plants. It is suggested to list O. japonica as the only original plant of Cyrtomium Rhizome and distinguish it from other frequently seen medical plants. Separated studies are also conducted for pesticide effect and active ingredients of Dryoteris Crassrhizomae Rhizome and Woodwardia japonica that show better effects.
