At a glance
The EMA classes peppermint oil as "well-established use" for two uses: gastro-resistant capsules for mild cramps, wind and abdominal pain, especially in irritable bowel syndrome (IBS), and oil rubbed on the forehead and temples for mild tension-type headache. Inhalation for coughs and colds and skin use for muscle pain and itching rest on traditional use. It must never be used in children under 2 because of the risk of reflex breathing arrest.
