Cuban oregano (Plectranthus amboinicus) is a leafy, aromatic plant used both for visual interest and for culinary purposes. Alternative names for this plant include false oregano, Spanish thyme, Mexican thyme and Mexican mint. The leaves possess both strong aroma and taste. Use the leaves fresh and chopped to compliment foods in a similar way as you would use other aromatic herbs, such as sage, rosemary and oregano.
