Exploring the efficacy and molecular mechanism of Danhong injection comprehensively in the treatment of idiopathic pulmonary fibrosis by combining meta-analysis, network pharmacology, and molecular docking methods
Medicine (2024) · Meta analysis · n=896
These results provided scientific basis for the clinical use of Danhong injection for the treatment of IPF, and provided a new direction to explore the potential mechanism of action of Danhong injection.
Based on single RCT (n=160) showing sleep improvement with various supplements including L-serine. Conservative estimates given limited direct evidence and lack of dose-specific data for L-serine alone. Effect likely mediated through conversion to glycine.
Evidence limited to systematic reviews and animal studies. Low bioavailability of standard luteolin forms significantly limits effectiveness. Human RCT data lacking for direct neuroprotective effects.
AI-estimated from published studies. Interpret as directional guidance.
Luteolin has a higher evidence score (8.5/10 vs 8.5/10) and wins in 1 of 3 categories.
For neuroprotection, L-Serine has a higher relevance score (75 vs 70).
No known interactions between L-Serine and Luteolin have been documented in our database. However, always consult a healthcare provider before combining supplements.
