Oregano is a staple ingredient in many Italian and Mexican dishes. The dry herb that we use to garnish our food comes from the leaves of a native Mediterranean herb.
This particular herb is one of the most concentrated antioxidant sources ever studied. In fact, it has been recorded by the U.S. Department of Agriculture (USDA) to have antioxidant activity between three and 20 times higher than any other herb or fruit. Even the popular antioxidant-rich blueberry falls short, when compared to oregano. It has four times the antioxidant activity of blueberries, 12 times that of oranges, and a whopping 42 times that of apples.
However, to reap the benefits of oregano for its antioxidants, you might have to use concentrated amounts of it. Apart from sprinkling it to your foods, you can also drizzle your salad with oregano essential oil.
