[Herbological study for the Beimu categorical Chinese medicine on the original plants].

This article reports the herbological study of "Beimu" categorical Chinese medicine on the original plants. The result showed that the medicinal "Beimu" before "Weijin" period is "Jia Beimu" (Bolbostemma paniculatum); "Nenbei" daynasty began to used "Zhe Beimu" (Fritillaria thunbergii), but "Jia Beimu" and "Hubei Beimu" (F. hupehensis) occupied an important position continuously; Last phase of "Ming" dynasty began to used the "Zhe Beimu" and "Chuan Beimu" (F. cirrhosa, F. unibracteato, F. przewalskii and F. delavayi) for "Beimu" greatly. The "Zhe Beimu" from Xiangshan, Zhejiang Province, is named "Xiang Beimu" and others are named "Tu Beimu" and the "Chuan Beimu" included the "Yi Beimu" (F. walujuewii and F. pallidiflora) continuously. So that, authors suggested that the contemporary documents such as Chinese Pharmcopoeia must recover the name "Beimu" to change the name "Tu Beimu" so as to avoid chaos with the "Tu Beimu" of the herbological documents; "Hubei Beimu" may take the place of "Zhe Beimu" but don't substitue for "Chuan Beimu"; "Yi Beimu" may be merged into "Chuan Beimu" to gear to actual circumstances and history; "Ping Beimu" to take the place of "Chuan Beimu" is not foundation from herbological documents.
