Garlic is an oft-touted natural remedy, particularly regarding affairs of the heart. Regular garlic consumption has been said to improve cardiovascular health. In the past, one way it was believed to improve health was its ability to reduce blood pressure.
A previous review found seven trials in which the effects of garlic (powder) were compared with placebo: Three showed a significant reduction in systolic blood pressure (the higher blood pressure value), while four showed a significant reduction in diastolic blood pressure (the lower blood pressure value). Overall, the results indicated that garlic had genuine blood-pressure-lowering potential.
Since this review was published, other evidence has come to light. Recently, scientists brought the state of the science on this topic up to date with a meta-analysis, which combined the results of eleven relevant studies.
The results demonstrated the following: overall, a statistically significant reduction in systolic blood pressure (an average reduction of 4.6) and overall, no statistically significant reduction in diastolic blood pressure. [Blood pressure is measured in mmHg.]
