Dried grapefruit peel is a colorful, fragrant and flavorful ingredient in cocktails, fruit drinks, syrups, bitters, and loose tea blends. It may also be tinctured or powdered and taken in capsule form. With a high concentration of potent antioxidants, the peel is also a functional addition to many topical products, such as soaps, salves, massage oils, facial serums, lotions and hair care products.
