Ginger tea is the most effective herbal tea for nausea, backed by more clinical research than any other option. But it’s not the only one worth trying. Peppermint, fennel, and even the scent of lemon in hot water can settle your stomach depending on what’s causing the nausea in the first place.
Ginger Tea: The Strongest Option
Ginger contains two compounds, gingerol and shogaol, that block nausea-related pathways in both the gut and the brain. They essentially keep the brain’s vomiting center from switching on. There’s also some evidence that ginger speeds up the rate at which your stomach empties, which helps when nausea comes from food sitting too long in your digestive tract.
The research behind ginger is substantial. One meta-analysis found that taking at least 1 gram of ginger per day for three or more days reduced the chance of acute vomiting during chemotherapy by 60%. For everyday nausea from motion sickness, overeating, or a stomach bug, ginger tea is a reliable first choice. To make it, peel and grate a thumb-sized piece of fresh ginger and steep it in boiling water for 5 to 10 minutes. The longer you steep, the stronger (and spicier) it gets.
For morning sickness, ginger has a strong safety profile. A Cochrane review of randomized trials using 975 to 1,500 mg per day found no significant differences in birth weight, gestational age, or congenital anomalies compared to controls. That dose range translates roughly to 2 to 4 cups of ginger tea per day, though the exact concentration varies with how you prepare it. If you’re pregnant and dealing with persistent nausea, ginger tea is one of the most studied and well-supported remedies available.
Peppermint Tea: Best for Cramping and Bloating
Peppermint works differently than ginger. Rather than blocking nausea signals in the brain, it acts as an antispasmodic, relaxing the smooth muscles in your digestive tract. This makes it especially useful when nausea accompanies cramping, bloating, or indigestion. It calms stomach muscles and improves bile flow, which helps your body process food more efficiently.
Peppermint has been studied most extensively for irritable bowel syndrome, where it reduces pain, bloating, diarrhea, and gas. If your nausea tends to come with a feeling of fullness or pressure in your abdomen, peppermint tea is likely the better pick over ginger. It may also help with chemotherapy-related nausea, though the evidence there is thinner.
One important caveat: peppermint can relax the valve between your esophagus and stomach, which may trigger or worsen acid reflux. If your nausea is related to GERD or heartburn, peppermint tea could actually make things worse. In that case, ginger or fennel is a safer bet.
Spearmint Tea: A Gentler Alternative
Spearmint is in the same family as peppermint but milder in flavor and effect. It relaxes stomach muscles in a similar way, helping ease nausea along with other digestive discomfort. If peppermint feels too intense or you find its cooling sensation overwhelming when you’re already queasy, spearmint is worth trying. To prepare it, bring a cup of water to a boil, remove it from the heat, add a handful of fresh spearmint leaves, and steep until it reaches the strength you want.
Fennel Tea: When Gas Is the Problem
Nausea doesn’t always start in the stomach. Sometimes it’s driven by bloating, trapped gas, or sluggish digestion lower in the GI tract. Fennel tea targets this kind of nausea specifically. It relaxes the smooth muscles of the gastrointestinal system and helps reduce gas and bloating, which can resolve the nausea along with them.
Fennel tea has a mild, slightly sweet licorice flavor. To make it, pour a cup of hot water over one teaspoon (about 2 grams) of dried fennel seeds and let it steep for 5 to 10 minutes before straining. You can also steep fennel roots or leaves if you have access to the fresh plant.
Lemon in Hot Water: The Scent Matters
Lemon doesn’t have the same muscle-relaxing or signal-blocking properties as ginger or peppermint, but it still helps many people feel less nauseated. The benefit appears to come largely from the aroma rather than the liquid itself. The smell of citrus is calming and can settle stomach discomfort, which is why Mount Sinai’s clinical guidelines recommend slicing citrus fruit and positioning it nearby while breathing deeply.
Adding a lemon slice to hot water gives you both the scent and gentle hydration, which matters more than people realize. Nausea often suppresses your desire to drink, and even mild dehydration can make the queasiness worse. If plain water feels unappealing, warm lemon water can be an easier way to keep fluids going. This trick also pairs well with the other teas on this list: a squeeze of lemon in ginger tea adds another layer of anti-nausea support.
Chamomile Tea: For Stress-Related Nausea
When nausea is linked to anxiety, stress, or general nervous stomach rather than a digestive issue, chamomile is a solid option. It has mild sedative and anti-inflammatory properties that calm both the nervous system and the gut lining. To make it, steep a tea bag or one tablespoon of dried chamomile flowers in a cup of hot water until it reaches the strength you prefer. Chamomile won’t do much for motion sickness or severe vomiting, but for low-grade queasiness tied to tension or poor sleep, it’s a comforting choice.
Choosing the Right Tea for Your Situation
- Morning sickness: Ginger tea, up to a few cups per day. It has the strongest safety data in pregnancy.
- Motion sickness or general nausea: Ginger tea, started before or at the onset of symptoms.
- Nausea with bloating or cramps: Peppermint or fennel tea, depending on whether the discomfort is more in the stomach (peppermint) or lower gut (fennel).
- Nausea with acid reflux: Ginger tea. Avoid peppermint, which can worsen reflux.
- Nausea from anxiety or stress: Chamomile tea, possibly with lemon.
- Chemotherapy-related nausea: Ginger tea has the most clinical support. Peppermint may help as a complement.
For any of these teas, fresh ingredients steeped in water you’ve just boiled will give you the highest concentration of active compounds. Pre-made tea bags are convenient and still effective, but a fresh knob of ginger or a handful of mint leaves will produce a stronger brew. If one tea doesn’t help after a cup or two, try a different one. The cause of your nausea determines which remedy works best, and sometimes it takes a bit of trial and error to find the right match.
