It is urgent to establish the limit standard of toxic components of Chinese herbal medicine, since the safety of traditional Chinese medicine (TCM) has attracted more and more attention.This paper analyzes the present situation and problems in the study of the limit standard of toxic components of Chinese herbal medicine. In addition, the current methods for setting the limit standards of toxic ingredients of TCM are reviewed in this paper, and we also propose a theoretical calculation method for setting the limit standards of toxic ingredients of TCM. Employing aristolochic acid as a case study, we formulate the limit standard of toxic components of Chinese herbal medicine. We believe this paper would provide some useful suggesting for formulating limits standard of toxic components of TCM.
Keywords: aristolochic acid; limit standard; toxic components; traditional Chinese medicine (TCM).
