Abstract: The mechanism of detoxification of Chebulae Fructus against Aconiti kusnezoffii radix toxicity, which was known as Mongolian medical theory, was studied by establishing network of active components-targets-pathways of detoxification and enrichment analysis of targets and pathways based on network pharmacology. Firstly, the targets of active components collected from TCMSP and TCM Database@Taiwan were obtained through SwissTargetPrediction compared with disease targets from OMIM, TTD, DiGSeE. Then, the target enrichment analysis of GO functional annotations and KEGG pathways and protein function were analyzed by Metascape, furthermore, the action between main active ingredients and targets was assessed by SystemsDock Web Site. At last, the Cytoscape was used to construct the network of active components-targets-pathways. In conclusion, there were 15 components and 40 targets related to the cardiotoxicity caused by Aconiti kusnezoffii radix. Furthermore, Chebulae Fructus could regulate cardiac function to detoxify the toxicity by Aconiti kusnezoffii radix through the biological process of negative regulation of blood vessel diameter, regulation of ion transport circulatory system process, muscle contraction inorganic ion homeostasis and the pathways of neuroactive ligand-receptor interaction, calcium signaling pathway, adrenergic signaling in cardiomyocytes, etc.
