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.
