Ginger tea and peppermint tea are the two strongest options for relieving indigestion, each working through a different mechanism. Ginger speeds up the rate your stomach empties, while peppermint relaxes the muscles in your digestive tract to ease cramping and spasms. The best choice depends on what type of indigestion you’re dealing with, because the same property that makes peppermint so effective for some symptoms can actually make acid reflux worse.
Ginger Tea for Fullness and Bloating
If your indigestion feels like heavy fullness after eating, nausea, or a sense that food is sitting in your stomach like a brick, ginger tea is the strongest pick. A clinical trial in patients with functional dyspepsia found that ginger cut the time it takes for the stomach to empty nearly in half compared to placebo: about 12 minutes versus 16 minutes. That faster emptying was linked to more frequent contractions in the lower part of the stomach, essentially helping your digestive system move food along more efficiently.
For a meaningful effect, you want roughly 1 gram or more of ginger. That’s about a one-inch piece of fresh ginger root, peeled and sliced thin, steeped in hot water for 10 to 15 minutes. Pre-made ginger tea bags work too, though they typically contain less ginger than a fresh preparation. Drinking it 20 to 30 minutes before a meal gives it time to start working before food arrives.
Peppermint Tea for Cramps and Spasms
Peppermint is best suited for indigestion that comes with cramping, gut spasms, or a tight, uncomfortable feeling in your abdomen. The menthol in peppermint prevents the smooth muscle lining your digestive tract from contracting too forcefully, which is why it’s been used for centuries as a stomach soother. Animal studies confirm this antispasmodic effect throughout the gut.
There’s one important catch: peppermint relaxes muscles everywhere in the digestive tract, including the valve between your esophagus and stomach. If your indigestion involves heartburn or acid reflux, peppermint tea can make it worse by allowing stomach acid to travel upward more easily. Research from the Medical University of South Carolina confirmed that peppermint relaxes this lower esophageal muscle. So if burning is your main symptom, skip peppermint and reach for ginger or chamomile instead.
Chamomile Tea for an Irritated Stomach
Chamomile is a good all-around choice when your indigestion involves general stomach irritation, mild nausea, or discomfort that doesn’t fit neatly into one category. The flowers contain over 120 active compounds, with a flavonoid called apigenin being the most studied. These compounds help reduce inflammation in the gut lining and ease smooth muscle spasms at the same time, giving chamomile a dual action that covers several types of indigestion.
Chamomile also has mild sedative properties, which makes it particularly useful for indigestion that shows up at night or feels worse when you’re stressed. Stress increases stomach acid production and disrupts normal digestion, so a tea that calms both your nervous system and your gut can address the problem from two directions. Steep for at least five minutes to extract enough of the active compounds from the flowers.
Fennel Tea for Gas and Flatulence
When indigestion shows up primarily as gas, bloating, or that uncomfortable pressure of trapped air in your intestines, fennel tea targets the problem directly. The key compound in fennel seeds, trans-anethole, is chemically similar to dopamine and relaxes the smooth muscles in your intestines. This helps trapped gas move through and pass rather than building up and causing pain. Fennel has also been shown to increase bowel movements, which helps clear gas from the lower digestive tract.
To make fennel tea, crush about one teaspoon of fennel seeds lightly with the back of a spoon to release the oils, then steep in boiling water for 7 to 10 minutes. The tea has a mild, slightly sweet licorice-like flavor that most people find pleasant on its own.
Licorice Root Tea for Acid-Related Discomfort
If your indigestion is tied to excess stomach acid or a raw, burning feeling in the stomach itself (not the esophagus), licorice root tea offers something the others don’t: it promotes mucus production in the stomach lining, creating a protective barrier against acid and digestive enzymes. This is the same principle behind some over-the-counter stomach coatings, just in a milder, plant-based form.
Look for deglycyrrhizinated licorice (often labeled DGL) if you plan to drink it regularly. Standard licorice contains a compound called glycyrrhizin that can raise blood pressure and lower potassium levels with frequent use. DGL versions have this compound removed while keeping the stomach-protective benefits intact.
Bitter Herb Teas for Sluggish Digestion
Some people experience chronic mild indigestion because their stomach doesn’t produce enough acid or digestive enzymes to break food down properly. This often feels like prolonged fullness, belching, or a vague heaviness after meals. Bitter herb teas, made from ingredients like dandelion root or gentian root, work by stimulating your bitter taste receptors. This triggers a chain reaction: your mouth produces more saliva, your stomach ramps up acid and enzyme production, and your whole digestive system shifts into a higher gear. According to Cleveland Clinic, people who don’t produce enough stomach acid on their own often benefit most from this approach.
Matching the Tea to Your Symptoms
- Nausea or heavy fullness after eating: ginger tea
- Stomach cramps or spasms (without reflux): peppermint tea
- General stomach irritation or stress-related upset: chamomile tea
- Trapped gas and bloating: fennel tea
- Burning or acid irritation in the stomach: licorice root tea (DGL)
- Chronic mild indigestion with low appetite: bitter herb tea
Safety During Pregnancy
Pregnant women commonly turn to herbal teas for indigestion, but the safety picture is more nuanced than most people realize. Peppermint tea is generally classified as safe in moderate amounts, though excessive use in early pregnancy is not recommended. Ginger should be used in limited quantities. Chamomile has been associated with a higher incidence of preterm labor when consumed regularly, leading some researchers to classify it as potentially unsafe during pregnancy.
A reasonable guideline across all herbal teas during pregnancy is no more than two cups per day. Tinctures, which are alcohol-based extracts, should be avoided entirely because they contain much higher concentrations of active compounds along with alcohol as a carrier. Herbal teas brewed from dried herbs in hot water contain the lowest concentrations and carry the least risk.
