Peppermint: A Whole New Way to Lower Blood Pressure.

Bet you’ve never thought of this one! Neither had science until now. A first of its kind study finds peppermint oil reduces blood pressure.

High blood pressure is the leading cause of cardiovascular disease and death from cardiovascular disease. It is also one of the most in your control. One way to do it is diet: eating more fruit and vegetables has been definitively shown to lower high blood pressure.

Another way is supplements. Until this new study, there has never been a study of peppermint oil on people with high blood pressure.

The double-blind study included 38 people with either prehypertension or stage 1 hypertension. Half were given a placebo, and half were given 50 mL of peppermint oil diluted in 100 mL of water twice a day for 20 days.

The peppermint oil was significantly more effective than the placebo. It reduced systolic blood pressure by 8.48 mmHg and diastolic blood pressure by 4.57 mmHg. And it did it safely with the same safety results as the placebo.

This first ever study of peppermint oil on people who actually have high blood pressure suggests that this safe and inexpensive natural treatment effectively lowers blood pressure.
