This pilot study demonstrates that pomegranate juice lowers blood pressure in patients with hypertension. Ten patients, ranging in age from 62 to 77, with an average blood pressure of over 155±7/83±7 drank 8 oz. (1.5 mmol total polyphenols equivalent) of POM Wonderful pomegranate juice each day for 2 weeks. This resulted in a 5% decrease in systolic blood pressure. ACE (angiotensin converting enzyme), which helps lower blood pressure, prevent heart disease and reduce the risk of stroke, was also decreased by 36%. Patients were already on ACE inhibitors or calcium channel blockers.
