digestive system

Peppermint has a great affinity with the digestive system and, as a carminative, antispasmodic and digestive juice and bile secretion stimulant; it can be used to treat indigestion, travel sickness, flatulence and colic. The essential oil acts as a mild anaesthetic to the stomach wall and allays feelings of nausea and the desire to vomit.

respiratory system

Peppermint is a cooling diaphoretic and useful for treating fevers associated with any type of infection, whether respiratory, digestive or urinary. This is especially useful when treating infants who have had a high fever causing febrile convulsions. Please note, however, that the essential oil is contraindicated in epilepsy as it is a mild neurotoxin in high doses due to its menthone content. The tea is safe, just avoid the oil for children, in high doses or for epileptics.
