Several herbal teas can calm an upset stomach, with ginger, peppermint, and chamomile being the most reliable options backed by research. The best choice depends on your specific symptoms: nausea, bloating, cramping, or acid reflux each respond better to different teas.
Ginger Tea for Nausea
Ginger is the strongest option if your main symptom is nausea. The root contains compounds called gingerols and shogaols that speed up stomach emptying, which means food doesn’t sit in your stomach as long and that “about to be sick” feeling fades faster. A study of people with irritable bowel syndrome found that taking one gram of ginger daily led to a 26% reduction in symptoms over four weeks.
You can make ginger tea by slicing a one-inch piece of fresh ginger root and steeping it in hot water for 10 to 15 minutes. Fresh ginger tends to be more potent than pre-bagged ginger tea, though both work. If you find the flavor too sharp, a small amount of honey rounds it out without interfering with the digestive benefits. Ginger tea is also one of the few options that’s well studied for morning sickness during pregnancy, though keeping intake moderate is wise.
Peppermint Tea for Cramps and Bloating
Peppermint works differently from ginger. Instead of speeding up digestion, it relaxes the smooth muscles in your intestinal wall. This makes it especially useful when your upset stomach involves cramping, spasms, or that tight, bloated feeling after eating. The menthol in peppermint is the active ingredient doing the work.
One important caveat: peppermint can relax the valve between your esophagus and stomach. If your upset stomach is actually acid reflux or heartburn, peppermint tea may make things worse by allowing acid to travel upward. Stick to ginger or licorice root tea instead if you feel a burning sensation behind your breastbone.
Chamomile Tea for General Discomfort
Chamomile is the best all-purpose option when you’re not sure exactly what’s going on. It has mild anti-inflammatory and antispasmodic properties, meaning it reduces irritation in the stomach lining while also easing muscle tension in the gut. It’s particularly helpful when stress or anxiety is contributing to your stomach problems, since chamomile has a gentle calming effect on the nervous system as well.
Chamomile is mild enough to drink multiple cups throughout the day. It’s a good choice for children with stomachaches, too, since the flavor is gentle and the effects are subtle. If you have a ragweed allergy, be cautious, as chamomile belongs to the same plant family and can occasionally trigger a reaction.
Fennel Tea for Gas and Trapped Wind
If your upset stomach is really about gas, pressure, and bloating, fennel tea targets those symptoms more directly than the options above. Fennel seeds contain a compound called anethole that relaxes the muscles of the gastrointestinal tract, helping trapped gas move through rather than sitting painfully in place. The flavor is mildly sweet with a licorice-like taste.
To make fennel tea, crush about one teaspoon of fennel seeds lightly (this helps release the oils) and steep them in hot water for 10 to 15 minutes. Pre-made fennel tea bags work too, though whole seeds tend to produce a stronger brew. Fennel is a traditional remedy that parents in many cultures give to babies with colic, which speaks to how gentle it is.
Licorice Root Tea for Acid-Related Stomach Pain
Licorice root stands out when your stomach upset involves a gnawing or burning pain, which often points to excess acid irritating the stomach lining. A form of licorice called DGL (deglycyrrhizinated licorice) promotes mucus production in the stomach and esophagus. That extra mucus acts as a protective barrier against acid, allowing irritated tissue to heal.
There’s an important safety note here. Regular licorice root contains a compound called glycyrrhizin that, in large or frequent doses, can lower your potassium levels and raise blood pressure. These aren’t minor side effects: they can lead to abnormal heart rhythms, muscle weakness, and swelling. If you want to drink licorice tea regularly, look for DGL licorice products that have the glycyrrhizin removed. For occasional use, a single cup of regular licorice tea is generally fine for most people, but it’s not one to drink daily over weeks.
Green Tea: Helpful but With Limits
Green tea contains catechins, a type of antioxidant that has anti-inflammatory effects on the digestive tract. Animal research has shown that green tea extract can suppress stomach inflammation and inhibit the activity of H. pylori, a bacterium that causes chronic stomach irritation and ulcers, in a dose-dependent manner.
The catch is caffeine. Green tea contains enough caffeine to stimulate acid production in the stomach, which can worsen nausea, heartburn, or an already-irritated gut. If you want the benefits without the drawback, choose a decaffeinated green tea or brew it lightly. Drinking green tea on an empty stomach when you’re already feeling off is likely to make things worse, not better.
How to Brew for Maximum Effect
The way you prepare herbal tea matters more than most people realize. For medicinal purposes, you want to steep for 10 to 15 minutes, not the 3 to 5 minutes that’s typical for flavor. Longer steeping extracts more of the volatile oils that provide digestive relief.
Cover your mug or teapot while steeping. Those essential oils are carried in the steam, so an uncovered cup loses potency as the aromatic compounds evaporate. Use water just off the boil, around 208°F, rather than water at a full rolling boil. And resist stirring during the steep, which also releases oils into the steam prematurely. These small adjustments can make the difference between a pleasant-tasting drink and one that actually settles your stomach.
Choosing the Right Tea for Your Symptoms
- Nausea or slow digestion: Ginger tea is the strongest, most studied option.
- Cramping or intestinal spasms: Peppermint tea relaxes gut muscles directly.
- Gas, bloating, or pressure: Fennel tea helps trapped gas move through.
- Burning or acid-related pain: DGL licorice root tea coats and protects the stomach lining.
- General queasiness or stress-related stomach upset: Chamomile tea is the gentlest all-around option.
You can also combine teas. Ginger-peppermint blends are widely available and cover both nausea and cramping. Chamomile-fennel is another common pairing that works well for bloating with general discomfort. Start with one cup and see how you feel before drinking more, especially if your stomach is sensitive enough that anything might set it off.
