Aged Garlic Shown to Help Lower Systolic Blood Pressure
Hypertension (high blood pressure) can lead to host of health problems, including heart disease. A recent study suggests that taking supplements of aged garlic may reduce systolic blood pressure (the top number in a reading) by up to 11.8 mmHg, which is similar to results seen with prescription antihypertensive medications.
The study included 79 participants with diagnoses of uncontrolled systolic hypertension who continued to take their prescribed antihypertensive medication for the duration of the trial. Over the course of 12 weeks, they underwent one of four interventions:
1. Low-dose: 240mg of aged garlic;
2. Medium-dose: 480mg of aged garlic;
3. High dose: 980mg of aged garlic.
At the conclusion of the study, the researchers noticed that the middle group had the highest reduction in systolic blood pressure, 11.8 mmHg. The highest dose group showed a reduction of 7.4 mmHg. The researchers not that the high dose of garlic was less tolerable, resulting in lower compliance in that group.
Previous studies have shown that reducing systolic blood pressure by 10 mmHg can reduce the risk of cardiovascular disease by 16-40.
The study was conducted by researchers at the University of Adelaide and the National Institute of Integrative Medicine in Melbourne, Australia. It was published online ahead of print on November 21, 2012, in the European Journal of Clinical Nutrition.
Aged garlic extract is a concentrated form of organic garlic that is odorless and richer in antioxidants than fresh garlic. Previous studies have shown that it helps lower cholesterol, lower blood pressure, reduce homocysteine, prevent atherosclerosis in coronary arteries by 50%,, increase circulation and boost immunity,
