Genetics, diet, and stress can cause high blood pressure (hypertension [1]), but a recent study [2] shows there's a way to lower it naturally. Drink three cups of hibiscus tea [3] a day. Look for this tea at your health food store, either solely hibiscus, or ones that are blended with this herb. The ability to lower blood pressure has to do with the actual plant and also the relaxing effects of sipping tea. Although your blood pressure may not decrease dramatically, even a small drop can benefit the body and lower your risk of the health problems associated with hypertension. Most people — 50 percent — are unaware that they even have high blood pressure [4], so if you haven't had yours checked in a while, see a doctor, or use one of those machines at your pharmacy. If it's on the high side, while you're out, pick up some hibiscus tea.
