Havij is the Persian word for the carrot. Its Latin name is Daucus carota. This page is about the single herb, used on its own.
Most people eat the orange root as food. In Persian and Unani medicine, the root, the juice and the seed are also used as home remedies. Old texts use it for the eyes, the skin, the gut, and to help the body pass more urine.
Carrot is a good food source of beta-carotene. The body turns beta-carotene into vitamin A. That part is well accepted by nutrition science.
The rest is less clear. Very few human trials test carrot itself as a treatment for any illness. Long use in a tradition is not proof that a remedy works, and we say plainly below where the proof stops.
The best understood part is simple. Carrot gives you beta-carotene, an orange plant colour. Your body turns some of it into vitamin A.
Vitamin A helps you see in dim light. It also helps skin and the immune system (your body's defence against germs) work in the normal way. So carrot helps most in people who are short of vitamin A.
Carrot also has fibre. Fibre adds bulk and water to stool, which can help you stay regular.
Other ideas are not settled. Lab work shows carrot holds antioxidants, which are things that guard cells from damage. Whether eating carrot changes the risk of any disease in people is still an open question.
Unani texts explain carrot in their own way, as a warm and moist food that clears the gut and the water passages. That is a traditional idea, not a tested one.
Common forms are:
Raw or cooked root, the usual food form.
Fresh carrot juice.
Dried root or root powder, used in Unani mixes.
Carrot seed, used in small amounts in traditional recipes.
Carrot seed essential oil, used on the skin in scent products. It is not for swallowing.
Beta-carotene capsules. These are made in a factory and are far stronger than food. They are not the same as eating carrots.
Carrot has been grown for food and medicine for well over a thousand years. Purple and yellow types came first, in and around Persia and Central Asia. The orange type became common in Europe much later.
Persian and Unani doctors listed carrot as a food-medicine for the gut, the urine and the sight. Greek, Arab, Indian and European folk healers used it in much the same way.
Some reactions to Havij need urgent care. Call your local emergency number or go to an emergency department straight away — do not wait to see whether it passes.
Get emergency help at once if your lips, tongue or throat swell, if you come out in hives, or if you struggle to breathe after eating carrot. That can be a severe allergic reaction.
See a doctor soon if the whites of your eyes turn yellow, if your urine turns dark, or if your skin yellows and you have not been eating much carrot. That is jaundice, not carotene, and it needs checking.
Also see a doctor if you have trouble seeing in dim light, if constipation lasts more than two weeks, or if you take warfarin and plan to start drinking carrot juice every day.
