 Mediterranean 
      and Mexican oregano are two different plants, 
      but because they are used 
      in the same way and have a somewhat similar flavor they are both called 
      oregano. Mediterranean oregano grows wild on the hilly mountainsides of 
      southern Europe and is an essential ingredient in so many of the dishes 
      from the region.  For Italian sauces to Greek salads, the sweet, 
      strong flavor of Mediterranean oregano is perfect.  Mexican oregano 
      is stronger and less sweet, well-suited to the spicy, hot, cumin-flavored 
      dishes of Mexico and Central America, perfect for chili and salsa. Both 
      types of oregano should be added in the beginning of cooking, so the 
      flavor has time to come out and meld with the other flavors of the dish.
