Celery Seed essential oil possesses a spicy, warm, long-lasting aroma, and is used as a fragrance component in soaps, cosmetics, and perfumes.[1] Limonene is the dominant constituent at about 70%, which puts Celery Seed in the same league as the bright and refreshing citrus peel and fir needle oils. However, it is the quiet and 'peppery' phthalides and β-selinene – influential secondary constituents – that are the critical actors here, imparting both the typical Celery fragrance and much of the effects.

Apium graveolens is a familiar biennial plant native to southern Europe and cultivated extensively as a domestic vegetable. The essential oil is primarily produced in India, Holland, China, Hungary, and the US.[2] The calming aroma is suitable for massage blends and diffusers, and its earthy qualities have led some perfumers to use it in place of Oakmoss Absolute.
