断血流药用历史及种质资源探讨

Discussion on medicinal history and germplasm resource of Clinopodium Herba

断血流药用历史比较久远，可以追溯至南宋《履蛲岩本草》的“草血竭”，其功效及用法记载明确。断血流的来源植物普遍认为是荫风轮Clinopodium polycephalum（Vaniot）C．Y．WuetHsuan与风轮菜C．chinensis（Benth．）O．Kuntze2个独立的种，也有学者认为荫风轮与风轮菜为同一种植物。荫风轮为断血流的主流来源，与风轮菜可能是原种与变种的关系。

By sorting out the literature on materiamedica,it is found that medicinal history of ClinopodiumHerba is rather long which can be traced back to caoxuejiein Lu chan yan ben cao （Mountainous Materia Medica） with definite efficacy and usage;it is generally believed that the original plant of ClinopodiumHerba is Clinopodiumpolycephalum （Vaniot） C.Y.Wu et Hsuan and C.chinensis （Benth.） O.Kuntze are two separate species, also some scholarsclaim that C.polycephalum and C.chinensisare the same plant.But I think C.polycephalum is the main origin of ClinopodiumHerba, and the relationship of C.polycephalum and C.chinensis maybe a species and its variety.
