Ginger tea is the most reliably effective tea for an upset stomach, backed by the strongest evidence for reducing nausea and improving digestion. But the best choice depends on your specific symptoms. Cramping and bloating respond better to peppermint, while heartburn and acid irritation call for something gentler like chamomile or licorice root tea.
Ginger Tea for Nausea and Slow Digestion
Ginger is the go-to for nausea, whether it’s from motion sickness, a heavy meal, or general queasiness. The active compounds in ginger root work in two ways: they have a direct antispasmodic effect on the gut, calming involuntary contractions, and they counteract delayed stomach emptying, helping food move through your system when digestion stalls. That combination makes ginger especially useful when your stomach feels heavy and unsettled at the same time.
To make ginger tea, slice about an inch of fresh ginger root and steep it in just-boiled water for five to ten minutes. Fresh ginger tends to be more potent than pre-bagged versions, though commercial ginger tea bags still deliver enough of the active compounds to help with mild symptoms. The tea has a spicy, warming bite. If that’s too intense, adding a small squeeze of lemon or a little honey softens the flavor without reducing the effect.
Peppermint Tea for Cramping and Bloating
If your upset stomach involves cramping, gas, or a bloated feeling, peppermint tea is the better pick. Menthol, the compound that gives peppermint its cooling sensation, works by blocking calcium channels in the smooth muscle lining your digestive tract. When those channels are blocked, the muscle can’t contract as forcefully. The result is a measurable reduction in the intensity of gut contractions without changing their rhythm. That’s why peppermint feels like it “relaxes” your stomach: it’s literally reducing the strength of the spasms causing your discomfort.
This same muscle-relaxing property is the reason peppermint tea comes with one important caveat. It can also relax the valve between your esophagus and stomach, lowering the pressure that keeps stomach acid where it belongs. In healthy people, this is rarely noticeable. But if you have acid reflux or GERD, peppermint can trigger heartburn or make existing heartburn worse. Menthol infused into the esophagus produces a cold sensation in healthy subjects but induces heartburn in people with reflux disease. If acid is part of your problem, skip peppermint and try one of the options below instead.
Chamomile Tea for General Stomach Discomfort
Chamomile is the mildest option on this list, which makes it a good default when you’re not sure exactly what’s wrong. It has gentle anti-inflammatory and antispasmodic properties, and it won’t aggravate acid reflux the way peppermint can. Chamomile also has a mild calming effect, which helps when your upset stomach has a stress or anxiety component. Nervous stomach and digestive discomfort often overlap, and chamomile addresses both at once.
The flavor is light and slightly floral. Steep a chamomile tea bag or a tablespoon of dried flowers in hot water for five minutes. It’s gentle enough to drink on an empty stomach without irritation.
Licorice Root Tea for Heartburn and Acid Irritation
When your upset stomach is really about burning, acid, or irritation in the upper stomach and chest, licorice root tea takes a different approach than the others. Rather than calming muscle contractions, it promotes mucus production in the stomach lining. That extra mucus acts as a physical barrier between your stomach tissue and acid, which can protect irritated areas and give them a chance to heal.
Look for tea made with deglycyrrhizinated licorice (often labeled DGL). Regular licorice contains a compound called glycyrrhizin that can raise blood pressure and cause potassium imbalances when consumed frequently. DGL has this compound removed while keeping the stomach-protective benefits. Most health food stores carry DGL licorice tea, and it has a naturally sweet taste that needs no sweetener.
Why Green Tea Can Make Things Worse
Green tea is often lumped in with “healthy teas,” but it’s one of the more likely to irritate an already-upset stomach. The tannins in green tea increase gastric acid production, which can cause nausea or reflux in sensitive individuals, especially on an empty stomach. Caffeine compounds the problem by stimulating gastrin, a hormone that speeds up the muscle contractions pushing food through your gut. For someone with a settled stomach, that’s fine. For someone already dealing with nausea, cramping, or diarrhea, it can make symptoms noticeably worse.
This effect is dose-dependent. Steeping green tea longer than five minutes significantly increases tannin concentration. Matcha, which involves consuming the entire ground leaf, delivers a much higher load of both caffeine and tannins than regular green tea and is more likely to cause stomach upset. If you want to drink green tea while your stomach is sensitive, keep the steep time short (two to three minutes) and don’t drink it on an empty stomach. But for active symptom relief, the herbal teas above are better choices.
How to Steep for Maximum Effect
The way you prepare herbal tea affects how much of the beneficial compounds end up in your cup. Research on steeping times shows that the majority of polyphenols extracted after ten minutes are already present within the first five minutes, regardless of tea type. So five minutes is the sweet spot for most herbal teas: long enough to get a therapeutically useful concentration, short enough to avoid over-extracting bitter tannins.
Water temperature matters too. Herbal teas like ginger, peppermint, and chamomile do best with fully boiled water (around 96°C or 205°F), which is hotter than you’d use for delicate green or white teas. Pour the water directly over the tea and cover the cup while steeping. Covering it traps the volatile oils, especially menthol from peppermint, that would otherwise evaporate into the air instead of staying in your drink.
Choosing the Right Tea for Your Symptoms
- Nausea or feeling like you might vomit: ginger tea, sipped slowly while warm
- Cramping, gas, or bloating: peppermint tea
- Heartburn or acid irritation: licorice root (DGL) tea or chamomile tea
- General uneasiness or nervous stomach: chamomile tea
- Heavy, overly full feeling: ginger tea, which helps the stomach empty more efficiently
You can also combine some of these. Ginger-chamomile and ginger-peppermint blends are common in commercial “stomach comfort” teas and cover a broader range of symptoms than any single herb. If you’re pregnant, commercially produced herbal teas in standard amounts are generally considered safe by the American Pregnancy Association, though teas made with excessive amounts of herbs or uncommon herbal blends deserve more caution. Sticking with well-known brands that follow FDA guidelines is the simplest approach during pregnancy.
