Ginger tea is the most well-supported option for settling an upset stomach, but peppermint, chamomile, fennel, and a few other herbal teas also work, each targeting different types of digestive discomfort. The best choice depends on whether you’re dealing with nausea, cramping, bloating, or general indigestion.
Ginger Tea for Nausea
If your main symptom is nausea, ginger tea is the strongest pick. The active compounds in ginger root reduce inflammation in the digestive tract by lowering levels of inflammatory signaling molecules and protecting cells from damage. In animal studies, these compounds significantly reduced nausea behaviors and lessened injury to the gastrointestinal lining. Ginger also helps move food through your stomach faster, which matters when that heavy, “food sitting like a rock” feeling is part of the problem.
The FDA considers up to 4 grams of ginger per day safe, which is far more than you’d get from a cup or two of tea. Ginger tea is less concentrated than capsules or extracts, so one to two cups a day is a reasonable amount without much risk of side effects. To make it, slice about an inch of fresh ginger root, steep it in hot water for 10 to 15 minutes, and strain. Fresh ginger produces a more potent brew than pre-made tea bags, though bags still work in a pinch.
Peppermint Tea for Cramps and Spasms
Peppermint tea is the go-to when your stomach upset involves cramping, tightness, or that uncomfortable squeezing sensation in your gut. Menthol, the main active ingredient in peppermint, works by blocking calcium channels in the smooth muscle of your intestinal wall. When calcium can’t flow into those muscle cells, the muscles physically can’t contract as forcefully. The result is a direct relaxation of the gut, which is why peppermint is classified as a natural antispasmodic.
This mechanism has been confirmed in human colon tissue, not just in lab animals, and the effect is independent of other pain-relief pathways. It’s a straightforward muscle relaxant for your digestive tract. One important note: if your discomfort is caused by acid reflux, peppermint can make things worse. That same muscle-relaxing effect can loosen the valve between your esophagus and stomach, letting acid travel upward.
Chamomile Tea for General Upset
Chamomile is the all-purpose option. It contains a compound called apigenin, which has anti-inflammatory and antioxidant properties that calm irritation throughout the digestive tract. Research shows apigenin can reduce inflammation caused by common gut irritants, including the bacteria H. pylori, by dampening the body’s inflammatory response and reducing oxidative stress in stomach cells.
Chamomile is a particularly good choice when your stomach upset comes with stress or anxiety, since it also has mild calming effects on your nervous system. That gut-brain connection is real: when your stress response settles down, your digestive system often follows. A warm cup before bed can address both the tension and the stomach discomfort at the same time.
Fennel Tea for Bloating and Gas
Fennel tea has an unusual dual action that makes it especially effective for bloating. Research published in Neurogastroenterology & Motility found that fennel tea relaxes the upper portion of the stomach (reducing that uncomfortable pressure and fullness) while simultaneously increasing the strength of contractions in the lower stomach, which helps push food and gas through more efficiently. In other words, it loosens the part of your stomach that feels tight while speeding things along where movement has stalled.
The key compound, anethole, has also been shown to restore normal stomach emptying when it’s been delayed. This makes fennel particularly useful after a large meal or when you feel uncomfortably full and gassy. Fennel tea has a mild licorice-like flavor. You can buy it in tea bags or crush about a teaspoon of whole fennel seeds and steep them in boiling water for 10 minutes.
Lemon Balm Tea for Indigestion
Lemon balm is a member of the mint family with a gentle citrus flavor, and it’s a common ingredient in over-the-counter herbal digestive remedies for good reason. It helps calm spasms in the gastrointestinal tract, making it useful for occasional gas, mild cramping, and general indigestion. Cleveland Clinic notes that lemon balm can be a helpful remedy when your gut feels unsettled, though it’s best suited for mild, occasional symptoms rather than chronic digestive problems like ongoing acid reflux or persistent abdominal pain.
Licorice Root Tea for Stomach Lining Protection
Licorice root takes a different approach than the other teas on this list. Instead of reducing spasms or speeding digestion, it increases production of mucin, a protective compound that coats the lining of your digestive tract. This coating shields your stomach from the corrosive effects of its own acid and other irritants. If your stomach upset feels more like a raw, burning sensation than cramping or nausea, licorice root tea may be the most targeted choice.
Look for “deglycyrrhizinated licorice” (often labeled DGL) if you plan to drink it regularly. Standard licorice root contains a compound that can raise blood pressure and lower potassium levels with frequent use. DGL versions have this compound removed while keeping the stomach-protective benefits.
Teas That Can Make Things Worse
Not all tea settles your stomach. Black tea contains high levels of tannins, compounds that give it its dark color and astringent taste. Drinking black tea on an empty stomach can actually trigger nausea, especially if you have a sensitive digestive system. Green tea has lower tannin levels but still contains enough caffeine to stimulate acid production. If your stomach is already irritated, both are worth avoiding until you feel better.
Eating a small amount of food alongside caffeinated tea helps. Proteins and carbohydrates bind to tannins and reduce their ability to irritate your digestive tract. But when your stomach is actively upset, sticking with caffeine-free herbal teas is the safer bet.
Choosing the Right Tea for Your Symptoms
- Nausea or slow digestion: ginger tea
- Cramping or spasms: peppermint tea
- Bloating or gas: fennel tea
- Stress-related stomach upset: chamomile tea
- Mild indigestion: lemon balm tea
- Burning or raw feeling: licorice root tea (DGL version for regular use)
For general stomach upset where you’re not sure what’s causing it, ginger or chamomile are the safest starting points. Both have broad mechanisms and minimal risk of making things worse. Drink your tea warm rather than hot, since extreme heat can irritate an already sensitive stomach lining. And if you’re using fresh herbs or roots, a longer steep of 10 to 15 minutes will extract more of the active compounds compared to a quick three-minute dip.
