Peppermint Oil Lowers Blood Pressure by 8 Points in 20 Days, Study Finds
In a 20-day UK trial with 40 adults who had pre-hypertension or stage 1 hypertension, daily intake of peppermint oil (50 μL in water twice daily) reduced systolic blood pressure by 8.48 mmHg (about 8 points) and diastolic by 4.57 mmHg, with resting heart rate about 9 bpm lower versus placebo. The effect may be due to menthol relaxing blood vessels, but results come from a small, short study and should not be generalized yet; larger, longer trials are needed.
