The Doctrine of Signatures states that every fruit and vegetable has a certain pattern that resembles a body organ, and that this pattern acts as a signal or sign as to that fruit or vegetable’s benefit to us. The cross section of a carrot, the pupil, iris and radiating lines look just like the human eye. And science now shows carrots greatly enhance blood flow to the eyes and aid in the general function of the eyes. Orange foods are high in beta-carotene, which our bodies transform into VitaminA and antioxidants. These nutrients aid in the prevention of cancer, heart disease, and infections by supporting an important part of the immune system. Beta-carotene also helps maintain healthy eyes and skin.
