Backgroud: According to the theory of traditional Chinese medicine (TCM), blood stasis syndrome (BSS) is the basis for many cardiovascular diseases. Ginger is often used as Chinese medicine (herb medicine) in China and Southeast Asia for the treatment of cardiovascular, respiratory, and digestive diseases. but the specific mechanism is unclear.Methods: After establishing an acute rat model of blood stasis syndrome, blood and urine of 5 groups of rats were collected for analysis of efficacy

Serum and urine were used for metabolomics, multivariate statistical analysis was used to explore metabolites and metabolic pathways, and the correlation between metabolites and pharmacodynamic indicators was further explored.Results: In this experiment, the model of blood stasis syndrome was successfully established based on changes in vascular disease and the efficacy index. The experimental results show that the efficacy indicators of dried ginger (DG) extracts of different doses have different degrees of changes than model group (MG), and the high dose of dried ginger group (GJH) changes are the most significant (p < 0.05 or p < 0.01). And 22 metabolites (10 in serum and 12 in urine) were identified and contributed to the blood stasis progress. These metabolites mainly involve seven metabolism pathways in different impact-value. Dried ginger has therapeutic effects on BSS rats by regulating multiple metabolic pathways.Conclusion: This study provides an effective method for understanding the metabolic mechanism of dried ginger extracts on BSS.
