Bay leaf essential oil (Laurus nobilis) is an aromatic oil obtained from the leaves of a plant associated with the Lauraceae family and Mediterranean region. It is known for its fresh, spicy, green, and slightly camphoraceous with a refined leafy warmth. and is used in perfumery, diffuser blends, and other traditional aromatic preparations.

Bay leaf essential oil from Laurus nobilis is valued in fresh herbal diffuser blends and invigorating aromatic formulas. It differs from West Indian bay oil and is usually chosen for its green spicy laurel aroma rather than its clove-heavy bay-rum character.

This oil is especially appreciated for its rosemary-style blending potential and is usually used in small amounts because its scent profile can strongly shape the finished aroma.
