title: [The textual research on the original plant of grass monkshood].
abstract: According to the literature review and field investigation, the traditional production areas of the herb grass monkshood are East China, Sichuan and its surroundings. The protophytes of grass monkshood in the east China area are mainly the Huangshan monkshood variant and truppelianum; but in the Sichuan area they are mainly aconite and aconitum hemsleyanum. The above belong to the aconitum of aconitum suby and tendril monkshood. They are the closest genetic relatives and the most evolutive groups as well as the most toxic groups. Local aconite was used as grass monkshood medicine in folk medicine but this happened only in part of the region and for a period of time. There were few records in literature in past dynasties and they would not have been able to be included in mainstream history. It is obviously different from the aconitum kusnezoffii which is stipulated in the pharmacopoeia in past ages. It is not in accordance with history to take kusnezoffii as certified quality grass monkshood and it also has some particular influence on the clinical use of grass monkshood.
