Wild celery is the plant that garden celery comes from. Its botanical name is Apium graveolens. In German it is called Echter Sellerie.
As a remedy, it usually means the seed rather than the stalk. Celery seed is sold as a spice, a tea, a tincture or a capsule. The stalks and juice are food.
European folk healers used it for gout, stiff joints and water build-up. The honest verdict: human evidence for these uses is thin and the few trials are small. Long traditional use is not proof that it works, and it is not proof that it is safe.
Food amounts suit most people. Strong seed extracts and the essential oil are a different matter, and celery is a well known cause of severe allergy.
No one has shown how wild celery works in the body in people. The ideas below come from lab dishes and animals.
Celery seed holds a group of oil compounds called phthalides. In animal studies these relaxed blood vessel walls and lowered blood pressure. Whether that happens in humans is not settled.
The plant also holds apigenin and luteolin, two flavonoids. In cell studies they damp down markers of inflammation. A change in a dish is not the same as an easier joint.
The old "flushing" idea rests on a mild water pill (diuretic) effect. That has been seen in animals. Good human proof is missing.
Celery seed contains coumarins, and raw juice carries nitrate. Both have been used to explain blood pressure or blood flow effects. These remain proposals, not proven paths.
You will meet wild celery in several forms:
- Fresh stalks and leaves, eaten as food. - Celeriac, the swollen root, also a food. - Raw celery juice.
- Dried seed, used whole or ground as a spice. - Celery salt, which is seed mixed with salt. - Seed tea, made from crushed seed.
- Tinctures made with alcohol. - Capsules of seed extract, often standardised for phthalides. - Essential oil, sold for scent and massage blends.
The essential oil is not for swallowing. Seed sold as garden stock may be treated with chemicals and is not food.
Celery has a long record in European and Mediterranean writing. Greek and Roman authors described it, and it appeared in Dioscorides. Wreaths of it were used at games and at funerals.
Medieval and early modern herbals carried it forward. Culpeper and other English writers listed it for wind, stopped water and "cleansing the blood". Folk use in German-speaking Europe leaned on the seed for gout and joint pain.
It also had a name as a food that stirred appetite and desire. None of this was tested in the way we test medicines now. The record tells you it was popular, not that it helped.
Call emergency services at once if you get swelling of the lips, tongue or throat, trouble breathing, widespread hives or faintness. These are signs of a severe allergic reaction.
Stop and see a doctor if you develop a blistering rash after sun exposure.
See a doctor rather than self treating if you have a hot, swollen joint, blood in your urine, burning when you pass urine, or swelling in both legs. Also get help if you feel dizzy or faint after starting a seed extract alongside blood pressure medicine.
In the EU, UK, US, Canada and Australia, celery is an ordinary food. Celery seed is a legal food spice and is sold as a supplement, not an approved medicine. In the EU and UK, celery must be named on food labels as an allergen.
