Does ginger help with blood pressure? What the research does and doesn't show

A 2026 systematic review pooling 41 randomized trials found systolic blood pressure was, on average, about 2.7 mmHg lower in people taking ginger than in people taking a placebo. Diastolic pressure showed no significant average difference. That's a small pooled average across trials that used very different doses and durations — not a tested result at one specific amount.

What the evidence doesn't support

It doesn't support ginger as a treatment for diagnosed high blood pressure or as a substitute for a prescribed blood pressure medication — no trial has tested it that way, and a 2.7 mmHg average is well short of what a medication is expected to achieve. It doesn't support one specific milligram amount, since the trials behind this pooled figure varied widely in dose and length and weren't broken out individually for the blood pressure result. And it doesn't support a diastolic pressure benefit at all — the same review found no significant average change there.

What the trials found

A 2026 systematic review searched four databases through January 2025 and pooled 41 randomized controlled trials of ginger supplementation, evaluating a range of outcomes including blood pressure, blood lipids and glycemic markers. Across the pooled trials, systolic blood pressure was on average 2.72 mmHg lower (95% CI -5.25 to -0.19 mmHg) in ginger groups than placebo groups — a statistically significant but small difference. Diastolic blood pressure was not significantly different between groups. The review's authors reported that effects across the pooled outcomes tended to be larger in trials that enrolled people who already had a metabolic condition (such as type 2 diabetes or metabolic syndrome) than in trials of healthy volunteers, and noted that dosage and duration varied enough across the 41 trials that a clear optimal amount couldn't be established.

No trial included in this pooled review was designed specifically to test ginger as a blood pressure treatment in people with diagnosed hypertension; the blood pressure figure is one outcome among several measured across a broader set of metabolic trials.

Questions people ask

Can ginger root lower blood pressure?

A 2026 pooled review of 41 trials found systolic blood pressure about 2.7 mmHg lower, on average, with ginger than placebo. That's a real but small average difference across mixed doses and trial designs — not a result from a trial built specifically to treat high blood pressure.

Is ginger root good for high blood pressure?

The pooled evidence shows a small average reduction in systolic pressure, with no measurable effect on diastolic pressure. It's not evidence that ginger treats diagnosed hypertension or replaces a prescribed medication for it.

Does ginger root raise blood pressure?

The pooled review found the average direction was a decrease in systolic pressure, not an increase, across the 41 trials it included.

How much ginger should I take for blood pressure?

The review doesn't report one dose tied to the blood pressure result specifically — doses varied across the 41 pooled trials. See how much ginger should you take a day for the range of amounts used across the wider ginger literature.

When to talk to a doctor

High blood pressure is diagnosed and managed medically, and ginger is not a treatment for it or a substitute for a prescribed medication. If you already take blood pressure medication, ask a doctor before adding ginger — combining it with a medication that acts on blood pressure the same way hasn't been specifically studied. See ginger and medications: what to check.
