It is an aromatic biennial with bulbous fleshy roots and solid grooved stems, pinnate divided leaves, up to 50 cm long. Gray-brown seeds follow umbels of green-white flowers. Celery is used externally to combat fungal infections and to battle tumors. The furocoumarins contained in celery are typically used for their stomachic, carminative, diuretic and emmenagogue properties. As a salad vegetable or made into a tea, celery can be helpful also in clearing up skin problems. A decoction of the seeds can be used for bronchitis, rheumatism and as a sedative for nervousness.
