CARROT

OTHER NAME(S):

Carota, Carotte, Cenoura, Danggeun, Daucus carota subsp. sativus, Gajar, Gelbe Rube, Hongdangmu, Hu Luo Bo, Karotte, Mohre, Mohrrube, Ninjin, Zanahoria.

Overview

Overview Information

Carrot is a plant. The leaves and the part that grows underground (carrot root) are used for food. The part that grows underground is also used for medicine.

Carrot root is used for Vitamin A deficiency. It is also used to prevent cancer, and for digestive health, obesity, other nutrient deficiencies, and other conditions, but there is no good scientific evidence to support these other uses.

In foods, carrot roots can be eaten raw, boiled, fried, or steamed. Carrot root can be eaten alone or added to cakes, puddings, jams, or preserves. Carrot root can also be prepared as a juice. Carrot leaves can be eaten raw or cooked.

How does it work?

Carrot contains a chemical called beta-carotene. Beta-carotene might act as an antioxidant and help to prevent cancer. Carrot also contains dietary fiber, which might improve stomach and intestine conditions such as diarrhea or constipation.

Uses

Uses & Effectiveness?

Possibly Effective for

  • Vitamin A deficiency. Some early research shows that eating carrot jam for 10 weeks improves growth rate in children with vitamin A deficiency. Other early research shows that eating grated carrot for 60 days improves vitamin A levels in some pregnant women who are at risk for not having enough vitamin A.

Insufficient Evidence for

  • Breast cancer. Population research suggests that eating more carrot might reduce the risk of getting breast cancer.
  • Diarrhea. Early research shows that giving a rehydration solution containing carrot and rice to infants and children with diarrhea helps shorten the length of time diarrhea is experienced.
  • Fibromyalgia. Early research shows that eating a vegetarian diet that includes drinking 2-4 servings of carrot juice for 7 months improves symptoms of fibromyalgia in some people.
  • Prostate cancer. Population research suggests that people who eat more carrots might have a lower chance of getting prostate cancer.
  • Cancer.
  • Constipation.
  • Diabetes.
  • Vitamin C deficiency.
  • Zinc deficiency.
  • Other conditions.
More evidence is needed to rate the effectiveness of carrot for these uses.

Side Effects

Side Effects & Safety

When taken by mouth: Carrot is LIKELY SAFE when eaten as a food. Carrot is POSSIBLY SAFE when taken in the larger amounts used as medicine for up to 4 weeks. Carrot might cause skin yellowing if eaten in large amounts.

When applied to the skin: There isn't enough reliable information to know if carrot is safe or what the side effects might be. Some people are allergic to carrot when applied to the skin.

Special Precautions & Warnings:

Pregnancy and breast-feeding: Carrot is LIKELY SAFE when eaten as a food if you are pregnant or breast-feeding. However, there isn't enough reliable information to know if carrot is safe to use as medicine when pregnant or breast-feeding. Stay on the safe side and stick to food amounts.

Children: Carrot is LIKELY SAFE when eaten as a food. But it is POSSIBLY UNSAFE to give large amounts of carrot juice to infants and young children. Large amounts of carrot juice might cause the skin to yellow and the teeth to decay.

Allergy to celery and related plants: Carrot may cause an allergic reaction in people who are allergic to birch, mugwort, spices, ivy, parsley, celery, and related plants. This has been called the "celery-carrot-mugwort-spice syndrome."
