Overview:Peppermint is a popular culinary and medicinal herb used around the world, often taken after a meal for its ability to reduce indigestion and colonic spasms by reducing what is called the gastrocolic reflex. Peppermint tea was also traditionally used in Europe as a medicine to treat colds, fevers, headaches, nervous tension, insomnia, and to alleviate digestive disorders including colic, flatulence, and dyspepsia. The German Commission E also recognizes peppermint for treating gall bladder disorders and bile deficiency. In European folk tradition, peppermint leaf tea was also used as an antispasmodic for treating menstrual cramps and as a sedative. Peppermint oil has strong antimicrobial properties and can be used both internally and externally. Menthol, the principal constituent of peppermint oil, is an anodyne (a pain-relieving medicine, milder than analgesic) used topically to treat neuralgia and inflammation of the mucous membranes of the nose.
