Ginger tea is the most well-supported option for an upset stomach, especially if nausea is your main symptom. But the best tea depends on what’s actually bothering you, whether that’s nausea, cramping, bloating, or general irritation. Several herbal teas target different types of digestive discomfort, and choosing the right one can make the difference between quick relief and just drinking a warm cup of water.
Ginger Tea for Nausea
If your stomach is churning and you feel like you might throw up, ginger tea is your best bet. The active compounds in ginger block a specific type of serotonin receptor in the gut that triggers the vomiting reflex. Since about 90% of the body’s serotonin is produced in the intestines, this receptor plays a major role in nausea, and ginger effectively dials it down. Ginger also speeds up gastric emptying, meaning it helps food move out of your stomach faster rather than sitting there making you feel worse.
For mild nausea, you can expect ginger tea to start working within 20 to 30 minutes. Some people need closer to an hour. Fresh ginger sliced into hot water tends to be more potent than pre-bagged ginger tea, though both work. Steep fresh slices for at least five minutes in near-boiling water to pull out enough of the active compounds. Two to three cups spread throughout the day is a reasonable amount for most adults.
Peppermint Tea for Cramps and Spasms
When your upset stomach feels more like cramping, tightness, or sharp pains in your abdomen, peppermint tea is often more effective than ginger. The menthol in peppermint directly relaxes the smooth muscle lining your intestines by blocking calcium from flowing into muscle cells. Without that calcium signal, the muscles can’t contract as forcefully, which reduces painful spasms.
This makes peppermint tea particularly useful for the kind of stomach upset that comes with irritable bowel symptoms, post-meal cramping, or intestinal discomfort that feels like things are “clenching” inside. One important caveat: if your upset stomach involves acid reflux or heartburn, peppermint can make it worse. The same muscle-relaxing effect that eases intestinal cramps also relaxes the valve between your stomach and esophagus, allowing acid to creep upward.
Chamomile Tea for Inflammation and Stress
Chamomile is the gentlest option on this list and works best for stomach upset tied to stress, mild inflammation, or general queasiness that doesn’t have one clear symptom. The key compound in chamomile suppresses several inflammatory pathways in the body, reducing the production of chemicals that cause redness, swelling, and irritation in the stomach lining. Animal studies have shown it can decrease visible signs of gastric inflammation at meaningful doses.
Chamomile also has mild sedative properties, which makes it a good choice when your stomach trouble is clearly linked to anxiety or tension. That nervous, unsettled stomach you get before a stressful event responds well to chamomile because it addresses both the physical inflammation and the mental state feeding into it. Steep chamomile in near-boiling water (around 96°C or just off a full boil) for at least five minutes to get a strong enough concentration of active compounds.
Fennel Tea for Bloating and Gas
If your “upset stomach” is really bloating, trapped gas, or that uncomfortable pressure feeling after eating, fennel tea is the most targeted choice. Fennel contains a compound called anethole that relaxes the muscles in the lower digestive tract, allowing gas to pass through rather than building up. This is why fennel has been used as a carminative (a fancy word for something that relieves gas) for centuries, including in gripe water given to colicky infants.
Fennel tea has a mild licorice-like flavor. You can make it from crushed fennel seeds steeped in hot water for 5 to 10 minutes, or use pre-made fennel tea bags. It also helps with the bloating that accompanies menstrual cramps, since the same muscle-relaxing effect works throughout the lower abdomen.
Licorice Root Tea for Stomach Lining Protection
Licorice root tea takes a different approach than the others. Instead of calming muscles or blocking nausea signals, it increases mucus production in the stomach, which coats and protects the lining. This makes it useful when your stomach upset involves a burning or raw feeling, as though the stomach itself is irritated or eroded. Multiple studies have shown this mucus-boosting effect can help prevent and heal ulcers.
One important note: regular licorice root contains a compound that can raise blood pressure and lower potassium levels if consumed in large amounts over time. If you want to drink licorice root tea regularly, look for “deglycyrrhizinated” versions (often labeled DGL) that have this compound removed. For occasional use when your stomach is bothering you, a cup or two of regular licorice root tea is fine for most people.
Teas That Can Make Stomach Upset Worse
Not all teas help a sensitive stomach. Green tea contains 25 to 45 mg of caffeine per cup and stimulates acid production. Drinking a strong green tea on an empty stomach can irritate the stomach lining, especially if you steep it longer than five minutes, which increases the concentration of tannins. Tannins are astringent compounds that can cause additional digestive discomfort. Black tea carries similar risks due to its higher caffeine and tannin content.
Matcha is even more likely to cause problems because you’re consuming the entire ground tea leaf rather than just a brewed extract. This means a much higher concentration of both caffeine and polyphenols hitting your stomach at once. If your stomach is already upset, stick with caffeine-free herbal teas and save the green tea, black tea, and matcha for when you’re feeling better.
Matching the Right Tea to Your Symptoms
- Nausea or vomiting: Ginger tea. It directly targets the nausea pathway and speeds up gastric emptying.
- Cramping or spasms: Peppermint tea. It relaxes intestinal muscles. Avoid it if you also have acid reflux.
- Stress-related stomach upset: Chamomile tea. It reduces inflammation and has calming effects.
- Bloating or gas: Fennel tea. It relaxes the lower gut and lets trapped gas move through.
- Burning or raw feeling: Licorice root tea. It coats the stomach lining with protective mucus.
You can also combine teas. Ginger and chamomile together cover nausea and inflammation. Peppermint and fennel together address cramping and gas. Most herbal teas are safe to drink alongside each other, and blending them is a common practice in traditional digestive remedies for good reason.
