Track Wild Carrot with reminders and record whether it helped, in the app.
Wild carrot is a common roadside plant, better known as Queen Anne's Lace. It is the wild parent of the garden carrot. Folk healers used its seeds, root and flat white flower heads.
American folk and Eclectic healers used it mainly for the urinary tract. They gave the seed for gravel, stones and water build-up. Some women took the seed hoping to avoid pregnancy.
The honest verdict: human evidence is almost absent. Long use in tradition does not prove that it works, and does not prove that it is safe. Wild carrot also looks much like poison hemlock, a plant that can kill.
Short answer: no one has shown how wild carrot works in people.
The seed holds a strong-smelling oil. In rat studies, seed extracts raised urine output. That fits the old use as a diuretic (something that makes you pass more urine).
In animal studies, extracts also relaxed smooth muscle and lowered blood pressure for a short time. Whether that happens in people is not known.
Rodent work suggests seed extracts can stop a pregnancy from taking hold. This has never been tested properly in women. That is a reason to avoid it in pregnancy, not a reason to trust it as birth control.
The plant makes furanocoumarins (natural chemicals that react with sunlight). These are known to burn human skin in sunlight. That effect is well established in people, not a lab guess.
Most wild carrot products are made from the seed.
Common forms: - Dried seed, brewed as a tea - Tincture, which is a liquid alcohol extract - Capsules of ground seed or seed extract - Carrot seed essential oil, sold for skin products and scent - Fresh root, eaten as a wild food
The essential oil is not for swallowing. It is very strong and is meant for outside use only.
The garden carrot in your kitchen is the same species. Eating food carrots is not the same as taking a wild carrot seed remedy.
Wild carrot has a long written record in Europe and North America.
Greek and Roman writers listed the seed for urine problems and for bringing on a late period. Medieval herbals copied those claims forward.
In the 1800s, Eclectic doctors in the United States used the seed for gravel, stones and dropsy (an old word for fluid swelling). King's American Dispensatory described seed tea for these uses.
Folklorists recorded Appalachian and other American women chewing the seed as home birth control. This went on well into the 1900s. It was never tested or approved as a way to prevent pregnancy.
Stop using it and see a doctor if any of these happen: - A rash, redness or blisters on skin that met sunlight - Severe or one-sided back or side pain - Blood in your urine, or you cannot pass urine - Dizziness, fainting or a very fast heartbeat - Period pain that is far worse than normal
Get emergency help at once for swelling of the lips, tongue or throat, or trouble breathing.
Call emergency services or poison control now if someone may have eaten hemlock by mistake. Warning signs include drooling, shaking, muscle twitching, weakness, seizures or trouble breathing.
In the United States, wild carrot seed is sold as a dietary supplement and is not an approved drug. In the UK and EU it is sold as a food or as an unlicensed herbal product.
