Raw garlic contains allicin, but most of this powerful ingredient is destroyed when garlic is cooked. Some studies have shown that taking garlic in tablet form reduces blood pressure up to 10 percent. Chewing garlic produces allicin, which then breaks down into beneficial compounds that help relax the blood vessels. However, the amount of raw garlic one would have to consume to reduce blood pressure would be quite large. It’s best to stick with a supplement to reap the most benefits.
If your goal is to come off of your high blood pressure medication, discuss some of these changes with your doctor first. You can monitor the positive effects of your lifestyle and dietary changes together, and then make the best choice for your health.
