Peppermint
Peppermint does more than just dress up a cocktail or freshen your breath. It ranks third, behind sage and oregano, in terms of antioxidant content, and it might actually keep you skinny. Simply smelling mint can reduce cravings, so much so that a study from Wheeling Jesuit University in West Virginia found that people who sniffed peppermint every 2 hours for a week consumed 2,800 fewer calories that week than non-peppermint-sniffers.
