While we all are familiar with peppermint as a flavoring in our favorite gum or candy, some people also use its leaves and oil as a remedy for digestive problems and a way to soothe headaches, inflammation and pain, among other complaints. It's also been considered a helpful treatment for coughs, colds, sinus and respiratory infections. In the laboratory, peppermint has been successfully used to kill some forms of bacteria, fungus and viruses, but this hasn't translated into any antibacterial, antifungal or antiviral benefits for humans yet. So far, there isn't enough evidence that peppermint is an effective treatment against coughing and the common cold.
