Adding vitamin-C packed citrus to tea can assist with detoxing the digestive system, says Dr. Salerno.
Boil water, then turn off heat. Allow tea bags and grapefruit to steep 5-10 minutes. Meanwhile, dissolve 1 part sugar into 1 part boiling water for simple syrup. Remove tea bags and pour tea into a gallon pitcher. Fill pitcher the rest of the way with cool water. Stir in no more than a tablespoon of simple syrup if the tea is too bitter. Chill 2-3 hours. Serve over ice.
