Purslane review finds a small systolic blood pressure reduction
Pooled trials favored purslane for systolic pressure, while the overall diastolic result remained inconclusive and study results differed substantially.
Based on the published abstract. The full paper may contain additional methods, results and limitations.
The 30-second takeaway
The pooled analysis suggested a small reduction in systolic blood pressure with purslane compared with control. It did not show a clear overall change in diastolic pressure. Because results varied greatly between trials, and the review measured blood pressure rather than cardiovascular events, the findings do not establish protection against heart disease.
Evidence certainty was moderate for systolic pressure and low for diastolic pressure, with concerns about applicability and precision. The abstract omits the overall duration range and details of purslane preparations.
What researchers found
Weighted mean difference in systolic blood pressure
Purslane versus placebo/control across trials; overall treatment-duration range was not reported.
What the abstract examined
The review pooled adult trials in which purslane was the only intervention. Systolic and diastolic blood pressure were analyzed separately, and the authors assessed differences across trials and certainty of evidence.
How to interpret subgroup signals
Some subgroup analyses suggested lower diastolic pressure among participants with diabetes and within certain age or duration categories. These signals do not establish dependable subgroup benefits, particularly given the low certainty of the diastolic evidence.
