Peppermint For Colds and Flu

If you have a dry cold, drink peppermint tea and it will almost immediately ease your symptoms. And if your friends are scared of catching it from you, or you wish to keep your family free from infection, tell them to rub a little peppermint oil under the nose and round the throat, and to take a small dose as well, it is an antiseptic and a strong preventative of disease.
