Never forage wild carrot. It looks almost identical to poison hemlock and water hemlock, both of which can kill. Buy seed only from a reputable herbal supplier.
Traditional carminative (traditionally used to settle gas and bloating) and mild diuretic (makes you pass more urine) action.
Essential oil (carotol, α-pinene) shows mild antimicrobial (slows the growth of germs) and antifungal activity in lab.
Source of luteolin and kaempferol flavonoid (a family of protective plant compounds) antioxidants.
Wild carrot grows abundantly across the Iranian plateau and the foothills of the Alborz. Its tiny aromatic seeds are quite different from the orange root of cultivated carrot. Since antiquity, people have used the seeds as a warming aid for gas, a urinary cleanser, and a women's regulating herb. Modern lab analysis confirms they carry a rich mix of essential oils (the concentrated aromatic oil of the plant) and flavonoids (a family of protective plant compounds).
Known to botanists as Daucus carota subsp. carota.

The Plant Itself
Biennial (living for two years and flowering in the second) herb 30–120 cm tall with finely divided fern-like leaves and a characteristic flat white umbel (a flat-topped cluster of small flowers, like the top of a dill plant), often with a single dark central floret. Aromatic seeds are the primary medicinal part. The wild ancestor of the cultivated carrot.
Family: Apiaceae (carrot family).

What Is In It

Notable: Essential oils: carotol, α-pinene, daucol · Polyacetylenes (plant compounds with antimicrobial properties found in carrot family plants)

What Lab Studies Show
From laboratory work, not from people taking it
Daucus carota seed extracts show diuretic (makes you pass more urine) and smooth-muscle relaxing activity in animal studies. Rated: early research.

What Studies in People Show
What studies in people show
Furanocoumarins (plant compounds that can make skin unusually sensitive to sunlight) in wild carrot can cause phototoxic skin reactions (skin injury triggered by sunlight) after contact with the fresh plant.Moderate evidence

Medicines and Interactions
General caution:
Hormonal contraceptives — Wild carrot seed has a long folk reputation as a contraceptive and may interfere with hormonal methods. Do not rely on either while using the seed. (moderate concern)
General caution:
Diuretics — The seed is a traditional diuretic (makes you pass more urine) and can add to water tablets. (low concern)
General caution:
Lithium — Any strong diuretic (makes you pass more urine) effect can raise lithium levels in the blood, which is dangerous. (high concern)

Who Should Be Careful
General caution:
DO NOT FORAGE without expert botanical identification — poison hemlock (Conium maculatum) and water hemlock (Cicuta) are look-alikes, and both can be deadly.
General caution:
Active kidney inflammation.
Pregnancy and breastfeeding:
Pregnancy, or trying to conceive: avoid entirely. Wild carrot seed has been used traditionally to prevent and end pregnancy, and animal studies support some of that effect.
General caution:
May increase photosensitivity in fair skin.
Allergy:
Known Apiaceae (carrot family) allergy.

Pregnancy, Children and Older Adults
Pregnancy and breastfeeding
Pregnancy and breastfeeding:
Avoid entirely during pregnancy and while breastfeeding. Wild carrot seed has been used traditionally to prevent and end pregnancy, and animal work supports some of that activity.
Children
Children:
Not for children. The identification risk alone rules it out, and there's no dose worked out for them.
Older adults
Older adults:
The diuretic (makes you pass more urine) effect matters more with age, particularly for anyone on water tablets or with kidney disease. Cultivated carrot gives the nutrition without the risk.

What Persian Medicine Says
Persian temperament: Hot & Dry (2nd degree). The seed rather than the root carries the reputation, and it's read as warming, drying and moving.
Persian medicine sees wild carrot seed as warm and dry, and diuretic (makes you pass more urine), carminative (herb that eases digestive gas), and emmenagogue (herb that encourages cycle regularity). Avicenna recommends a small daily dose of the seeds for cold-type urinary retention, sluggish digestion, and to promote a regular monthly cycle.
Carminative (traditionally used to settle gas and bloating) seed tea for gas, bloating, and colicky cramping.
Traditional emmenagogue (traditionally used to bring on a menstrual period): to encourage delayed cycles.
Cooling poultice (a soft paste held against the skin) from crushed seeds for skin inflammation.

What It Goes With
Pairing:
Fennel
Both are carrot-family seeds used for wind and cramping.
Spice:
Cumin
Cumin is the everyday kitchen version of the same warming seed idea, and much easier to get.
Pairing:
Carrot
The garden carrot is the same species, bred for its root.
Honey:
Honey
The seed tea is sharp and honey makes it drinkable.

Through the Year
Spring:
Spring
First-year rosettes appear. The root is edible now and woody later, but identification is hardest at this stage.
Summer:
Summer
The white umbels [flat-topped clusters of small flowers, like the top of a dill plant] open, each with the single dark floret at the centre that names the plant.
Autumn:
Autumn
Seed harvest. The heads curl inward into the classic bird's nest and the seed comes away easily.
Winter:
Winter
Dried seed only, used a pinch at a time.
