Most research shows that oral ingestion of peppermint oil can help relieve stomach bloating in individuals with irritable bowel syndrome, according to the National Institutes of Health. However, it does not appear to relieve post-surgery stomach bloating.
Peppermint oil may also assist in alleviating mild to moderate cases of stomach pain, gas and diarrhea in individuals with irritable bowel syndrome, reports Healthline. Additionally, the combination of peppermint oil and caraway oil is a potential treatment for soothing indigestion, according to a few small studies.
Individuals should consult with a doctor before using peppermint oil as a medical treatment, as it can be dangerous in incorrect doses and may interact with other medications. However, moderate consumption of fresh peppermint leaves and dried peppermint tea is considered to be safe, says Healthline.
