Peppermint tea for gas is a popular home remedy, but the honest answer is “maybe, a little, and not for everyone.” The best studies test peppermint oil capsules in people with irritable bowel syndrome (IBS), not a cup of tea. A warm cup may still help you relax and ease mild cramps after a heavy meal. It can also make heartburn worse. This guide explains what the research shows, how to brew a cup, who should skip it, and when gas needs a doctor.
What does peppermint tea for gas actually do?
Peppermint leaves contain menthol, an oil that gives mint its cool taste. In lab and gut studies, menthol is thought to relax the smooth muscle in the gut wall. Relaxed muscle may mean fewer cramps and an easier path for trapped gas.
That is the theory. The proof in people is narrower than most websites suggest. Here is what we can say, and what we cannot.
- Verified: Enteric-coated peppermint oil capsules beat a placebo for IBS symptoms and belly pain in adults.
- Not shown: That brewed peppermint tea removes gas or bloating. NCCIH, the US National Center for Complementary and Integrative Health, says the evidence for peppermint leaf is very limited.
- Opinion, not proof: That a hot drink “feels” soothing. Warmth and a quiet five minutes can help you feel better, whatever the menthol is doing.
What does the research say?
The strongest evidence is a 2019 meta-analysis in BMC Complementary and Alternative Medicine. It pooled 12 randomized trials with 835 adults. Peppermint oil was better than placebo for overall IBS symptoms (risk ratio 2.39) and for belly pain (risk ratio 1.78). You can read the details in the 2019 meta-analysis of peppermint oil for IBS.
A risk ratio of 2.39 means people on peppermint oil were about 2.4 times as likely to report improvement as people on placebo. It does not mean symptoms dropped by 139 percent.
Three limits matter for you:
- These trials used enteric-coated capsules. The coating lets the oil reach the intestine before it is released. A tea releases menthol in the mouth and stomach instead.
- The people had IBS. Gas from a big dinner or from beans is a different problem.
- A cup of tea holds far less oil than a capsule, so we cannot assume the results carry over.
NCCIH’s page on peppermint oil safety and effectiveness, last updated in May 2025, says a small amount of research suggests enteric-coated capsules may improve IBS symptoms in adults. It also lists heartburn, nausea, belly pain and dry mouth as possible side effects.
Peppermint tea for gas versus capsules: which is which?
Many articles mix these two up. This table keeps them apart.
| Peppermint tea | Enteric-coated peppermint oil capsules | |
|---|---|---|
| What it is | Dried or fresh leaves steeped in hot water | Concentrated oil in a coated capsule |
| Tested for IBS in trials | No good trials found | Yes, in many trials |
| Menthol amount | Low and varies by brand and brew | Set by the maker |
| Main risk | Heartburn in some people | Heartburn, nausea, belly pain |
| Good for | A gentle, low-risk habit for people without reflux | A doctor-guided option for IBS |
If you have been told you have IBS, ask your doctor about capsules instead of drinking six cups of tea and hoping for the best.
Is peppermint tea for gas right for your kind of gas?
Not all gas is the same. Matching the symptom to the right step saves time. This is a practical guide, not a medical test.
| What you feel | Likely cause | What to try first |
|---|---|---|
| Burping and fullness right after meals | Swallowed air, fizzy drinks, eating fast | Slow down, skip straws and fizzy drinks. Peppermint is a poor first pick if you also have heartburn. |
| Cramps and trapped wind, often with changes in toilet habits | Could be IBS | See a doctor. Capsules are the studied option, not tea. |
| Gas after beans, lentils, cabbage or onions | Gut bacteria ferment hard-to-digest carbohydrates | Smaller portions, soaking pulses well. Tea is optional. |
| Burning in the chest, sour taste | Acid reflux | Skip peppermint. It may make this worse. |
| Bloating with constipation | Slow gut movement | Water, fibre and walking. See a GP if it keeps happening. |
The NHS bloating advice agrees with this simple approach: chew with your mouth closed, eat smaller meals, move your body, and limit fizzy drinks and gas-producing foods. It does not list peppermint as a treatment.
How to make peppermint tea for gas
If you want to try peppermint tea for gas, keep it simple. These steps are common kitchen practice, not a tested medical dose.
- Use about 1 teaspoon of dried peppermint leaf, one tea bag, or a small handful of fresh leaves for one cup (about 250 ml).
- Pour freshly boiled water over the leaves.
- Cover the cup and steep for 5 to 7 minutes. Covering keeps more of the aroma in the cup.
- Strain and sip slowly, ideally after a meal.
- Skip sugar if you can. A little honey is fine for adults.
Check the label. Some “mint” blends contain spearmint, fennel, or other herbs. In India, the fresh pudina sold in markets is often a different mint than true peppermint, so the taste and menthol level can differ. That is fine for a pleasant cup, but do not assume it behaves like the peppermint in studies. If you like a milder mint, our guide on how to make spearmint tea shows the difference.
Never add peppermint essential oil to your drink. It is far stronger than the leaf and can be unsafe to swallow.
A two week test of peppermint tea for gas you can run at home
You can find out if peppermint tea helps you without guessing. Gas has many causes, so this keeps the test fair.
- Days 1 to 3: Write down when you have gas, what you ate, and how bad it felt from 1 to 10. Change nothing.
- Days 4 to 14: Drink one cup of peppermint tea for gas after your largest meal. Keep the same notes.
- Change only one thing. If you also cut out fizzy drinks, you will not know which step helped.
- Compare: If your scores do not improve after two weeks, the tea is not your answer. Stop and move to food changes or a doctor visit.
This is our suggested method, not a study. Its value is that it stops you from crediting the tea for a change that came from eating slower.
Who should avoid peppermint tea for gas?
Peppermint tea for gas is safe for most healthy adults in food-like amounts, but it is not for everyone.
- People with acid reflux or GERD. Peppermint may relax the valve between the stomach and food pipe, which can let acid rise. The IBS trials also report more heartburn-type side effects with peppermint oil in some reviews.
- People with gallstones or bile duct problems. Ask your doctor first.
- People on regular medicines. NCCIH advises talking to your provider before using any herbal product. If you take antacids, many guides suggest spacing peppermint a couple of hours apart. Ask your pharmacist.
- Pregnancy and breastfeeding. NCCIH says oral peppermint in food amounts is likely safe, but little is known about medicinal amounts. Stick to one cup and check with your doctor.
- Babies and young children. NCCIH warns that peppermint oil should not be applied to the face of infants or young children, because inhaled menthol can cause serious side effects. Do not give strong peppermint tea to babies. Never give honey to children under one year.
- Anyone allergic to mint-family plants. Stop if you get a rash, swelling, or trouble breathing.

Does peppermint tea count toward your daily water?
Yes. Peppermint tea has no caffeine, so it counts toward fluid intake like plain water. We explain this in more detail in our post on whether peppermint tea counts toward daily hydration. Drinking enough fluid also helps if your bloating comes with constipation.
Common questions about peppermint tea for gas
How fast does peppermint tea for gas work?
There is no reliable data on timing for tea. Some people feel calmer within 20 to 30 minutes, but that may come from warmth and rest. If nothing changes after two weeks of trying, it is probably not helping you.
Can I drink peppermint tea every day?
For most healthy adults, one to three cups a day of ordinary peppermint tea is a common habit. No strong long term safety data for daily tea exists, so stop if you notice heartburn, nausea, or mouth dryness.
Is peppermint tea better than ginger tea for bloating?
We cannot say it is. Neither has strong trials for gas in the form of tea. Ginger is often used for nausea, and peppermint is the one with capsule research for IBS. Choose by your symptoms and by which one your stomach tolerates.
When should I see a doctor about gas and bloating?
See a GP if bloating happens regularly, keeps coming back despite diet changes, or comes with unplanned weight loss or blood in your stool. Get urgent help if bloating comes with vomiting, a swollen hard belly, fever, or sudden severe stomach pain. These are the NHS warning signs.
The bottom line
Peppermint tea for gas is a low-cost, low-risk habit for many people, but it is not a proven treatment. The real evidence is for oil capsules in IBS, not for peppermint tea for gas itself. Try the two week test, watch for heartburn, fix the basics such as eating slowly, and see a doctor if symptoms persist or worsen.
