The essential oil of oregano (riganelaio) is used in perfume and medicine. The word "oregano" comes from the composition of the words "oros" (mountain) and "ganos" (joy) and means the joy of the mountain.Oregano is widely used in Greek and Italian cuisine, in grilled meats, poultry, fish, pizza, pasta sauces, beans, etc. It is also used to give flavor and aroma in vegetables, wines, and salad dressings.
