Oregano gives fragrance an aromatic green profile with peppery, savoury and slightly camphoraceous facets. Used most often in the top or heart of a composition, it provides definition and herbal lift rather than sweetness, making the opening feel brisk and distinctive.
In men's fragrances, oregano commonly appears alongside citrus, basil, lavender, spices and woods. Its character shifts with the surrounding materials: citrus and other herbs keep it crisp and energetic, while cedar, vetiver, leather or amber can draw out a drier, warmer side. Choose this note if you enjoy Mediterranean-style aromatics, herbal freshness and compositions with a more savory edge.
