Apium graveolens, more commonly known as wild celery, is a biennial growing to 60cm tall. It is part of the umbelliferae family. Wild celery prefers moist soil and grows in ditches, by rivers, and near the sea.
Wild celery has been eaten and used medicinally for a long time. It reduces blood pressure, relieves indigestion, and is anti-inflammatory. An essential oil extracted from the plant is said to have a calming effect on the central nervous system. Raw or cooked, celery leaves can be used as a flavoring agent. However, they can be toxic in large amounts. The seeds are used in small quantities as a flavoring agent, as are the roots when cooked.
