Medicinal Uses
Taken internally, peppermint oil is used to relieve symptoms of irritable bowel syndrome
(IBS) and other digestive disorders, including flatulence and gastritis. When applied
externally, it is used for the relief of muscle pain (myalgia) and headaches.

inflammation of the gastrointestinal tract or gallbladder, or those with impaired liver

Warnings
• Peppermint oil should never be applied to the face, particularly near the nose of infants or
young children, as it may cause respiratory distress.
• Because the oil is highly irritant, it should be taken only in enteric-coated capsules to
prevent gastric irritation.
• It should be avoided by patients suffering from digestive ulcers, acid reflux, or ulcerative
colitis.
• Individuals with achlorhydria (absence of stomach acid), particularly those taking H₂-
