Peppermint tea is the most widely supported option for gas relief, but ginger, fennel, and chamomile teas also have carminative properties that help break up or prevent intestinal gas. Each works through a slightly different mechanism, so the best choice depends on what’s causing your discomfort.
Peppermint Tea
Peppermint is the go-to recommendation for a reason. Menthol, the main active compound in peppermint, works by reducing calcium flow into the smooth muscle cells lining your stomach, intestines, and colon. When those muscles can’t take in as much calcium, they relax instead of contracting. That relaxation is what eases the cramping and pressure you feel when gas gets trapped in your gut. This is the same mechanism behind peppermint oil capsules, which are sometimes recommended for irritable bowel syndrome.
One cup of strong peppermint tea after a meal is a reasonable starting point. Steep for at least five minutes with a lid on the mug to keep the volatile oils from escaping with the steam. If you experience acid reflux, though, be cautious: peppermint relaxes the smooth muscle at the bottom of your esophagus too, which can let stomach acid travel upward. People who already deal with heartburn or reflux may find peppermint makes that particular symptom worse, even as it helps with gas lower in the digestive tract.
Ginger Tea
Ginger tackles gas from a different angle. Rather than relaxing muscles to release trapped gas, ginger speeds up the rate at which food leaves your stomach and moves through your digestive system. The key compound, gingerol, promotes what’s called gastrointestinal motility. When food doesn’t sit in your stomach as long, it has less time to ferment and produce gas in the first place.
This makes ginger tea particularly useful if your gas tends to come with a feeling of uncomfortable fullness or nausea after eating. Fresh ginger sliced into hot water works well, and commercial ginger tea bags are fine too, though fresh ginger tends to be more potent. Drinking it 20 to 30 minutes before a meal can help prevent gas rather than just treating it after the fact. Ginger is also one of the gentler options for people who are pregnant, as it has a long track record of use for nausea during pregnancy.
Fennel Tea
Fennel seed tea has been used for digestive discomfort across cultures for centuries, and recent research helps explain why. The main active compound in fennel, trans-anethole, appears to do two things at once in different parts of the stomach. In the upper stomach, it acts as a muscle relaxant, easing tension and cramping. In the lower stomach (the antrum, which pushes food toward the intestines), it acts as a prokinetic, meaning it encourages the muscles to contract and keep things moving. That dual action, relaxing where there’s spasm and stimulating where there’s sluggishness, is unusually well suited to the kind of mixed discomfort that comes with gas and bloating.
A single cup of fennel tea made from crushed seeds can deliver a meaningful concentration of anethole to your stomach. Research analyzing fennel tea brewed according to standard instructions found that the anethole concentration in the stomach could reach roughly 107 micrograms per milliliter when consumed on an empty stomach. To make fennel tea at home, lightly crush about one teaspoon of fennel seeds, pour boiling water over them, and steep for seven to ten minutes.
Chamomile Tea
Chamomile is a milder option, but it works on two fronts that matter when you’re dealing with gas. Its volatile oils have a direct carminative effect, meaning they help break up gas bubbles in the digestive tract. At the same time, chamomile relaxes the smooth muscles of the stomach and intestines, easing the cramping and tightness that often accompany bloating. If your gas tends to get worse in the evening or when you’re stressed, chamomile has an added benefit: one of its flavonoids promotes relaxation and sleep, which can indirectly help with stress-related digestive issues.
Chamomile is also a good choice when you want something gentle enough to drink multiple times a day. It doesn’t carry the reflux risk that peppermint does, and it has very few interactions or side effects for most people.
Lemon Balm Tea
Lemon balm is less well known as a digestive tea, but it has a traditional history of use for bloating and gas. It’s a member of the mint family with a mild lemony flavor. Animal studies suggest it can ease intestinal spasms and support regular bowel movements, though human studies on lemon balm alone for gas are still limited. It’s one of the key ingredients in Iberogast, a European herbal digestive supplement that has shown benefits for abdominal pain and bloating in clinical settings. On its own, lemon balm tea is pleasant, very mild, and worth trying if you find peppermint too strong or if reflux is a concern.
How Herbal Teas Compare to OTC Gas Medications
You might wonder whether tea actually does anything compared to over-the-counter options like simethicone (the active ingredient in Gas-X and similar products). The comparison is more interesting than you’d expect. In randomized controlled trials studying colic, simethicone performed no better than placebo in any of three separate studies. A herbal tea blend containing chamomile, fennel, and lemon balm, by contrast, significantly reduced symptoms, with a number needed to treat of just three. That means for every three people who drank the herbal tea, one experienced meaningful relief that wouldn’t have happened with placebo.
A 2025 meta-analysis of five randomized controlled trials found that herbal medicines showed a small but statistically significant positive effect on functional gastric disorder symptoms, with a pooled effect size of 0.105. That’s a modest benefit, but it’s consistent, and it’s more than simethicone has demonstrated in controlled settings. The practical takeaway: herbal teas aren’t a miracle cure, but they do appear to have a real physiological effect on gas and bloating.
Choosing the Right Tea for Your Symptoms
The best tea depends on the pattern of your symptoms. If you feel sharp, crampy pain from trapped gas, peppermint or fennel is your best bet because of their direct antispasmodic effects. If your bloating comes with a heavy, overly full feeling after eating, ginger is the better choice because it speeds up digestion. If your gas tends to flare with stress or anxiety, chamomile’s calming properties give it an edge. And if reflux is part of the picture, skip peppermint entirely and reach for chamomile, fennel, or lemon balm instead.
Combining teas can work well too. Fennel and chamomile together is a classic European digestive blend. Ginger and peppermint complement each other by addressing both slow digestion and muscle spasm. Drinking your tea warm (not scalding) and sipping it slowly tends to work better than gulping it down, because warmth itself helps relax the gut and slow sipping prevents you from swallowing extra air, which would only add to the gas problem.
