Now we’re going to get down to how these natural blood thinners work. These foods keep your blood and heart-healthy, and we’re going to start with onions. Onions are rich in vitamin C, flavonoids, and phytochemicals. Flavonoids, such as quercetin, are potent antioxidants that can help your body get rid of the free radicals responsible for cancer. Phytochemicals trigger healthy reactions in the human body, allowing the body to function at its best. What’s excellent about onions is that you can still reap these rewards, whether raw or cooked, since the cuisine process doesn’t break down the nutrients too much.
