Although celery (Apium graveolens) is more familiar as a vegetable than as a medicine, it can be used in the treatment of rheumatism, arthritis and gout.  Containing apiol, the seeds are also used as a urinary antiseptic. Celery is a good cleansing, diuretic herb, and the seeds are used specifically for arthritic complaints where there is an accumulation of waste products.  The seeds also have a reputation as a carminative with a mild tranquilizing effect.  The stems are less significant medicinally.
