Lemon Peel

Lemon peel is the familiar cut and dried yellow outer layer of the lemon. Although orange peel is more commonly prescribed in traditional Chinese and Ayurvedic medicine, lemon peel also stimulates the appetite by encouraging the release of gastric juices to digest food, and helps provide vitamin C. Lemon peel is added to scores of herbal teas and herbal formulas for aroma and taste enhancement.

Many people eat lemon peel. A recent study in Arizona found that the regular consumption of lemon peel greatly reduced the risk of skin cancer caused by sun exposure. 
Lemon peel also provides citrus bioflavonoids that help stabilize capillaries, helping to heal varicose veins, bloodshot eyes, and hemorrhoids (when the lemon peel is used to make a tea that is drunk).
