- Carrot (Daucus carota) is a well-known root vegetable. The thick tap root's color can range from white to orange to red or purple. This change in color represents the nutrients in the carrot because some pigments, such as beta-carotene and lycopene, are also nutrients.
- Carrot probably originated around Afghanistan where there is the greatest variety of carrots today. Usually only the root is consumed, although the leaves are also edible. Although primarily used as a food source, carrots have also traditionally been used to treat infantile diarrhea. Carrot roots have been used to treat digestive problems, intestinal parasites, and tonsillitis. Other potential uses include vitamin A deficiency, antioxidant activity, constipation, and anemia. More research is need in all of these areas as the currently available research is of low quality.
