Turmeric and Reduced Blood Pressure

Research synthesisModerate evidenceMixed effect size3 studies · 2 beneficial · 1 neutral · 0 harmful

Across 3 studies (2 reviews and 1 meta-analysis), 2 reported beneficial effects on blood pressure with small to moderate effect sizes, while one meta-analysis in patients with type 2 diabetes or hyperglycemia found no significant effect.

Caveats: Evidence base is small (only 3 studies) — conclusions should be considered preliminary. All three studies are reviews or meta-analyses; individual trial characteristics may vary. One meta-analysis specifically in type 2 diabetes or hyperglycemia showed neutral results, suggesting the effect may depend on population.
