Animal traditional Chinese medicine has a long history of application in China, and its clinical application is very extensive. Due to the complex chemical composition in animal traditional Chinese medicine, the basis of chemical research is relatively weak, which leads to the unclear composition and toxic components of many animal Chinese medicines. The relationship between the medicinal and toxic components of animal Chinese medicine has not yet been elucidated. The non-clinical safety evaluation of animal traditional Chinese medicine mainly includes acute toxicity, long-term toxicity, safety pharmacology, reproductive toxicity, genotoxicity experiments, and experimental studies such as carcinogenicity are needed when necessary. The current preclinical safety research on animal traditional Chinese medicine is mainly based on the study for toxic animal traditional Chinese medicines. Most animal Chinese medicines have not carried out systematic preclinical and clinical safety studies. The research method is mainly focused on acute toxicity test. It is necessary to carry out systematic preclinical safety studies on animal traditional Chinese medicines, to clarify the possible side effects and its characteristics, its toxic target organs, toxic doses and poisoning mechanisms induced by different animal traditional Chinese medicines. Finally, this paper suggests that in the preclinical safety study of animal traditional Chinese medicine, in-depth research and comparison should be carried out in combination with chemical substance foundation, origin, and collection season, and the safety of "non-toxic" animal traditional Chinese medicine should be carried out when necessary. In addition, it is necessary to rationally use the cutting-edge technologies and methods of toxicology research to fully clarify the preclinical safety information of animal Chinese medicines.
