New evidence
Turmeric's curcumin slashed systolic blood pressure in a meta-analysis of 894 people — but the finding comes from a COPD review, not a blood pressure trial.
This is the first solid signal that curcumin might meaningfully lower systolic blood pressure, but the effect was observed within a COPD-specific meta-analysis, so it needs direct replication in a general population before it's actionable.
A systematic review of dietary polyphenols in COPD patients found that curcumin (from turmeric) significantly reduced systolic blood pressure by a large amount (effect size -0.82) compared to placebo. However, this result is embedded in a review focused on lung disease, and the overall evidence for curcumin's blood pressure effect remains novel and unconfirmed outside COPD. The dose ranged from 200 to 500 mg/day.
Where this fits in the evidence
This is among the first studies we've indexed on Turmeric for Reduced Systolic Blood Pressure — treat it as an early signal until more research accumulates.
