(NaturalNews) A naturally occurring plant compound found in onions may reduce high blood pressure if consumed regularly, according to a new study conducted by researchers at the University of Utah and published in the Journal of Nutrition.

Researchers studied 22 adults with hypertension and 19 adults with pre-hypertension, giving them each either a placebo or a 730-milligram supplement of quercetin each day. The blood pressure of the patients with hypertension who were given quercetin decreased by approximately 7 mmHg systolic and 5 mmHg diastolic relative to those who had been given the placebo. Among the pre-hypertension patients, neither the placebo nor quercetin-supplemented groups experienced a significant change in blood pressure.
