Hibiscus tea for high blood pressure?

Nutrition researchers at the US Department of Agriculture report that hibiscus tea reduced blood pressure in a random, controlled trial. The higher the blood pressure, the greater the effect. However, the sample was quite small - 65 people in both control and experimental groups. This would need to be replicated with a much larger sample.
