Peppermint Oil for irritable bowel syndrome
Enteric-coated peppermint-oil capsules may modestly improve IBS symptoms such as abdominal pain, bloating, and gas over the short term. Evidence quality is low and individual trials are mixed; long-term benefit has not been established.
What this means
Short-term relief of global IBS symptoms in adults using an oral enteric-coated peppermint-oil capsule comparable to studied products; not a claim for peppermint tea, leaf, food, aromatherapy, topical oil, or undiluted essential oil.
How to use it: Use only a labeled oral enteric-coated capsule intended for IBS-type gastrointestinal use. Do not substitute peppermint tea, food, inhalation, topical preparations, or homemade essential-oil capsules. Reassess if symptoms persist and address IBS subtype, diet, fibre, and other established therapies.
Safety & cautions
Peppermint oil can cause reflux, heartburn, belching, nausea, abdominal discomfort, and perianal burning. It may be unsuitable for people with significant GERD or hiatal hernia. Do not swallow undiluted essential oil or improvise capsule doses.
Get medical care for symptoms that are severe, last longer than expected, get worse, or otherwise concern you.
Household preparations
Practical ways to use the ingredient may not provide the same form or amount discussed in the evidence.
