Carrot, also called miniature ginseng, has the carrier of Vitamin A in its whole fruit oil, after the absorption, the carrier will be converted into two molecules of Vitamin A, so it can be used for all the diseased caused by lack of vitamin A. Though carrot whole fruit oil is mostly stored in liver, it won't have any toxic side effects due to over-doze, that is the very reason that it is also called non-toxic Vitamin A.
