[Research on the original plants of Gou-wen and Ye-Ge--and the herbological thoughts of Jin].

Ye-Ge exists in the SHOOSOUIN, and the herbal origin was decided as Gelsemium elegans Bentham. On the other hand, Gou-Wen may be a general term that means poison plants as well as Jin. At least four kinds of Gou-Wen were known in ancient times: three herbs and one wood-like plant. The shi-leaf Gou-Wen may be Gelsemium elegans Bentham, in short, the same as Ye-Ge. The huang jing-leaf Gou-Wen may be Croomia heterosepala. The qin-leaf Gou-Wen may be Cicuta virosa L. The wood-like Gou-Wen may be Coriaria nepalensis Wall.
