Peppermint oil lowers blood pressure in just 20 dayshttps://www.sciencedaily.com/releases/2026/08/260821012238.htm
Peppermint oil may have an unexpected benefit for people with mildly high blood pressure. Adults who took a small dose twice daily for 20 days saw their systolic blood pressure fall by an average of 8.5 mmHg, while a placebo group showed little change. Researchers say the inexpensive oil could eventually provide a simple additional option for managing elevated blood pressure.
