Oregano is an herb that originated in the Mediterranean region. It is used both fresh and dried, but actually is much more flavorful when dried.
Oregano is a good source of fiber, iron, and manganese and contains a wide variety of health-promoting antioxidants as well. Per gram, oregano actually has 4 times as much antioxidant activity as blueberries! (Check out more oregano nutrition facts on World's Healthiest Foods.)
