- Black Currant and Blood Pressure
Black currant lowered blood pressure during recovery from moderate-intensity exercise. In this study, 10 men and five women, average age 31, healthy, untrained, with normal blood pressure, took a placebo or 600 mg of black currant extract daily for seven days, pausing for two weeks, then switching groups.
Doctors measured blood pressure and heart rate after a two-hour supine rest that followed a moderate one-hour treadmill exercise at 50 percent of maximum oxygen usage. Systolic pressure decreased 5.6 vs. 3.5 mmHg for placebo, and fat burning increased 66 percent vs. no change for placebo.
