Peppermint, botanically Mentha piperita, is a herbal medicine traditionally used for mild digestive complaints such as bloating, flatulence, fullness or minor abdominal spasms. Depending on the product, the leaves, essential oil or extracts may be used. Its effect is symptomatic and it does not treat serious causes of abdominal pain.
It is taken by mouth as tea, gastro-resistant capsules, drops or extract, according to the leaflet. Peppermint oil capsules should not be broken or chewed, because they may irritate the stomach. Products intended for external or inhalation use must not be swallowed. If digestive symptoms persist for more than a few days or recur frequently, medical assessment is needed.
Side effects may include heartburn, reflux, nausea, irritation of the mouth, rash or allergic reactions. People with gastro-oesophageal reflux disease, hiatus hernia, gallstones or other biliary disorders should be cautious, because peppermint may worsen heartburn or colic. Concentrated essential oil is not suitable for young children.
Seek medical help if severe abdominal pain, persistent vomiting, black stools, blood in the stool, fever, jaundice, weight loss or breathing difficulty after use occurs. During pregnancy, breastfeeding and childhood, only age-appropriate products should be used and medical advice is recommended. Peppermint may help minor discomfort, but it does not replace diagnosis.
