Armoise essential oil (Artemisia herba-alba) is an aromatic oil obtained from the aerial parts of a plant associated with the Asteraceae family and North Africa and the Mediterranean region. It is known for its sharp, herbaceous, camphoraceous, and slightly bitter with a wild green edge. and is used in perfumery, diffuser blends, and other traditional aromatic preparations.

Armoise essential oil has been used in traditional herbal settings for cleansing aromatic blends and strongly herbaceous preparations. Because Artemisia oils may contain thujone and other potent constituents, armoise should be handled with extra caution and is not considered an everyday oil for routine use.

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