Aged Garlic Extract May Lower Blood Pressure in People with Uncontrolled Hypertension
Uncontrolled hypertension occurs when people are either not adhering to their blood pressure treatment regimen, have inadequate treatment, or have treatment resistance. It is particularly dangerous because it can lead to damage to the heart and coronary arteries, heart attack, heart failure, or stroke. A recent study suggests that taking aged garlic supplements may reduce mean blood pressure by as much as 5 mmHg in people with uncontrolled hypertension.
Participants in the study included 88 people with uncontrolled hypertension who were given either 1.2 grams per day of aged garlic extract or a placebo for 12 weeks. At the conclusion of the study, the researchers noted a mean blood pressure reduction of 5 mmHg in the aged garlic group. Systolic blood pressure was reduced by an average of 11.5 mmHg and diastolic blood pressure was reduced by an average of 6.3 mmHg. No changes were noted in the placebo group.
They also noted improvements in central blood pressure, mean arterial pressure, pulse-wave velocity, and arterial stiffness in the aged garlic group. However, these changes were not statistically significant. The aged garlic extract was highly tolerable and acceptable, with no increased risk of bleeding in those participants on blood-thinning medication.
Researchers from Australia’s National Institute of Integrative Medicine conducted the study. It was published on January 27, 2016, in Integrated Blood Press Control.
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, reduce homocysteine, prevent atherosclerosis in coronary arteries by 50%, increase circulation and boost immunity.
