Propolis and Reduced C-Reactive Protein Levels

Research synthesisModerate evidenceModerate effect3 studies · 3 beneficial · 0 neutral · 0 harmful

Across 3 meta-analyses, all reported beneficial moderate-to-large reductions in C-reactive protein (CRP) levels with propolis supplementation. The strongest evidence comes from a 2025 systematic review of 12 RCTs in people with type 2 diabetes, showing a moderate effect (MD = -2.68, 95% CI: -3.48 to -1.89). Effect sizes were predominantly moderate across studies.

Studied populations: people with type 2 diabetes

Caveats: Evidence base is small (only 3 studies) — conclusions should be considered preliminary. Available evidence is overwhelmingly positive — clinical literature in this area is subject to publication bias (null-result studies are less likely to be published or indexed). Study durations and doses were not consistently reported, limiting dose-response insights.
