Objective To investigate the mechanism of Sini Powder in treatment of major depressive disorder, generalized anxiety disorder, breast fibrocystic disease with the "homotherapy for heteropathy". Methods The active components of Sini Powder were screened and compared the drug-like properties with existing drugs for the treatment of major depressive disorder, generalized anxiety disorder, breast fibrocystic disease using principal component analysis. Multiple databases were used to analyze the targets of Sini Powder and three diseases, DAVID database was used to conduct GO enrichment and KEGG pathway analysis of common targets, BioGPS database was used to locate and analyze the key targets. Corticosterone (CORT) induced PC12 cells was used to prepare models of depression. Sini Powder (6.250 0, 3.125 0, 1.562 5 mg·mL^-1) was used for intervention treatment. Cell survival was detected by MTT, IL-1β and IL-6 mRNA expression was tested by qRT-PCR. Results Most of the active components of Sini Powder had good drug-like properties. There were 32 common targets of Sini Powder treating three diseases with "homotherapy for heteropathy". The key targets were IL6, TNF, TP53, AKT1 and IL1B, etc. The key active components were quercetin, luteolin, and nobiletin, etc. Sini Powder mainly played the role of treating different diseases through HIF-1, pathways in cancer and PI3K-Akt signaling pathway. It was speculated that the liver and thymus were the key parts of the drug. The results of cell experiments showed that Sini Powder could reverse the cytotoxicity of CORT on PC12 and affected the mRNA expression of IL-1β and IL-6. Conclusion The treatment of three diseases with Sini Powder reflected the thought of "homotherapy for heteropathy" in Chinese medicine through multiple components, multiple targets, and multiple pathways by regulating inflammatory response and other factors.
