New evidence
A meta-analysis found propolis supplementation lowered systolic blood pressure by 5.58 mmHg. The catch: the trials were unblinded, diastolic pressure didn't change, and the underlying studies showed moderate disagreement.
As one of the first pooled analyses on propolis and blood pressure, this finding is an intriguing early signal — but the unblinded design, the null result for diastolic pressure, and the moderate heterogeneity across trials mean it's far from conclusive.
Propolis supplementation was associated with a 5.58 mmHg reduction in systolic blood pressure (the top number) in a meta-analysis of controlled trials, though the optimal dose was not specified. However, the underlying studies were not blinded, which makes the results susceptible to bias, and diastolic blood pressure (the bottom number) did not change significantly. The individual trials also showed moderate disagreement, and this is among the first analyses of its kind, so the evidence should be treated as preliminary.
Where this fits in the evidence
This is among the first studies we've indexed on Propolis for Reduced Systolic Blood Pressure — treat it as an early signal until more research accumulates.
