The lemonade diet drink, or master cleanse drink, is designed to rid your body of toxins that have accumulated through a lifetime of eating, breathing, and living. You wouldn't believe what's inside of you! The drink consists of lemon juice (must be fresh!), purified water, grade B organic maple syrup, and cayenne pepper. Sometimes you will hear it referred to as the "lemonade, maple syrup, cayenne pepper diet," but I find that too complicated.
