Exploring synergistic effects of Achyranthes bidentata Blume and Paeonia lactiflora Pall. on hypertension with liver yang hyperactivity using the multidisciplinary integrative strategy

Pall. (PL) for hypertension with liver yang hyperactivity (HLYH). The integrated research consisting of principal component analysis (PCA), metabolomics, microbiology, and weighted correlation network analysis (WGCNA) were used to find the optimal combination of AB-PL combinations and reveal the mechanism of action. The result showed AB-PL (2:3) had a substantial protective impact on HLYH, as shown by lower blood pressure, improved liver yang hyperactivity, reduced cardiac remodeling and malondialdehyde (MDA), and increased NO content. Furthermore, the essential elements for AB-PL reducing hypertension may be related to 135 metabolites and 23 microorganisms. In conclusion, our findings support the efficacy of herbal remedies in the treatment of hypertension and provide some pharmacological evidence for the ongoing development of novel modern Chinese drugs for cardiovascular disorders.
