› Health benefits
Peppermint is commonly used to address a variety of health concerns, including irritable bowel syndrome (IBS), general digestive discomfort, the common cold and certain types of headache. Applied topically, peppermint oil is also used to relieve muscle aches, itching and tension.
Irritable bowel syndrome
Peppermint oil has been most thoroughly researched for its effects on IBS. Multiple trials suggest that enteric-coated peppermint oil capsules can reduce symptoms of IBS, such as abdominal pain and bloating.
Some preliminary studies have examined combination products containing peppermint and caraway oil for indigestion relief. While initial results are promising, the specific product studied is not widely available in the United States and more research is needed.
Headaches
Topical peppermint oil has a history of use for tension-type headaches. A limited body of evidence indicates that applying peppermint oil to the temples or forehead may provide short-term relief for some people.
› How much do I need?
Appropriate peppermint oil dosage varies by age and by the condition being treated. Follow the directions on product labels, and consult a pharmacist, physician or other qualified healthcare professional before beginning use.
Potential side effects include allergic reactions and heartburn. Enteric-coated capsules are commonly used to reduce the risk of heartburn associated with oral peppermint oil.
When applied to the skin, peppermint oil can cause irritation or rash in sensitive individuals. Do not apply peppermint oil to the face or chest of infants or young children; inhaling menthol from the oil can lead to serious breathing problems.
› Dietary supplements
Peppermint oil is sold in several forms, including liquid solutions and capsules. Enteric-coated capsules are a common choice for those using peppermint oil for digestive issues.
