celery seed

Celery seed refers to the tiny, seedlike fruits of the celery plant (Apium graveolens). These seeds are dried and used as a condiment, offering a taste and aroma similar to the plant itself.12

Celery seeds are particularly useful as a seasoning in soups and pickles. They contain an essential oil rich in compounds like phthalides and terpenes, which contribute to celery's characteristic aroma. Historically, celery seed has also been employed in herbal medicine, traditionally used as a diuretic and for its anti-inflammatory properties to address conditions such as rheumatism and gout.23

Celery seed oil, also known as celery oil, is a colorless to yellowish essential oil derived from these seeds. It is primarily utilized as a flavoring agent due to its distinct celery odor and taste.4
