Scientists Discover Cheap, Natural Remedy for High Blood Pressure

A small randomized trial found that peppermint oil may help lower mildly elevated blood pressure.

In the study, 40 adults with prehypertension or stage 1 hypertension took 100 microliters twice daily for 20 days.

The peppermint oil group saw an average 8.5 mmHg drop in systolic blood pressure, while the placebo group changed little.

Researchers say larger studies are needed, but peppermint oil could become a low-cost option with fewer side effects.
