Celery is a good source of potassium. It has a diuretic effect, can help control blood pressure and has anti-inflammatory effects.

Celery is most nutritious eaten raw, but is still beneficial when cooked.

Wild celery can be found throughout Europe, the Mediterranean, and parts of Asia. The leaves, stalks, root, and seeds can be eaten. In western cuisine, the stalks of its domesticated cousin are commonly used in cooking and may be eaten raw alone or in salads, or as a cooked ingredient in various recipes. Celery seed has also been used as a diuretic (increase urine flow) and to treat gout (foot inflammation). However, there is insufficient evidence in humans to support the use of celery for any indication.
