This well-known aromatic herb grows wild in the mountains and rocky areas all over Greece. The flowers are collected, dried, rubbed and sieved into tiny particles. Oregano is an indispensable herb in Greek cooking. It adds flavour to a Greek salad. It is usually added to the lemon-olive oil sauce that accompanies many fish or meat barbecues and some casseroles. Oregano (Origanum vulgare) is prized not only for its strong flavour and pleasant aroma, but also for its health benefits. Oregano has antibacterial properties and also potent antioxidant activity. It is a very good source of iron, dietary fiber, calcium, vitamin C, vitamin A and omega-3 fatty acids.
