The orange peel is chock full of vitamins- almost as much as the fruit itself. It contains Vitamin C, which helps in boosting the immune system and improves health in general. It also contains high amounts of antioxidants, which help in fighting free radicals that in turn lower the risk of diseases. Orange peel has a refreshing aroma and taste, which makes it a wonderful addition to delicate tea. A cup is sure to liven you up at the end of a long day, and the relaxing properties help ease muscle tension.
