Ginger tea is the most effective tea for nausea, backed by more clinical evidence than any other herbal option. It works by blocking serotonin receptors in the gut that trigger the vomiting reflex. But ginger isn’t the only option. Peppermint, chamomile, fennel, and honey lemon tea can all help settle your stomach depending on what’s causing your nausea in the first place.
Ginger Tea: The Strongest Evidence
Ginger contains a group of active compounds called gingerols and shogaols that interfere with the signaling pathway your body uses to trigger nausea. Specifically, they act on the same receptors that prescription anti-nausea drugs target: the serotonin receptors in your gut lining. When these receptors fire, they send “time to vomit” signals to your brain. Ginger’s compounds don’t block the receptor directly but bind to a nearby site on the same receptor complex, dampening the signal in a dose-dependent way. The stronger the ginger, the stronger the effect.
In a clinical trial published in the American Journal of Obstetrics & Gynecology, pregnant women who took 1 gram of ginger daily experienced the same reduction in nausea scores as women taking dimenhydrinate (the active ingredient in Dramamine) over a seven-day period. The key difference: 77% of the Dramamine group reported drowsiness, compared to only 6% of the ginger group. During the first two days, ginger was slightly slower to reduce vomiting episodes, but by day three the two treatments were equally effective.
To make ginger tea, grate a small knob of peeled fresh ginger and steep it in boiling water for 10 to 20 minutes. A longer steep makes a stronger, more pungent cup. If you’re using dried ginger powder, a half teaspoon per cup is a reasonable starting point. Keep your total daily intake below 5 grams, as higher amounts increase the risk of heartburn, burping, and stomach discomfort.
Peppermint Tea: Best for Stomach Cramping
Peppermint works differently from ginger. Rather than blocking nausea signals directly, it relaxes the smooth muscle in your intestinal walls. This makes it particularly useful when your nausea comes with bloating, gas, or crampy abdominal pain. A 2023 review found that peppermint oil can relax intestinal muscles and relieve pain, and may help manage symptoms of irritable bowel syndrome.
Research on peppermint for chemotherapy-related nausea has also shown promise. Interestingly, some of the benefit appears to come simply from the scent. A 2020 clinical trial found that inhaling peppermint oil helped prevent nausea and vomiting, which means even holding a warm cup of peppermint tea near your face and breathing in the steam may provide some relief before you take your first sip.
Most studies focus on concentrated peppermint oil rather than brewed tea, so the effects of a cup of tea will be milder. To get the most out of it, crush 10 to 15 fresh peppermint leaves and steep them in a cup of hot water for 10 to 15 minutes. Pre-bagged peppermint tea works fine too, though it tends to be less potent than fresh leaves.
Chamomile Tea: For Stress-Related Nausea
If your nausea tends to come on with anxiety, tension, or an overall unsettled feeling, chamomile is worth trying. It has mild sedative and anti-inflammatory properties that can calm both your nervous system and your digestive tract. Chamomile won’t act as quickly or as powerfully as ginger for acute nausea, but it’s a good option when you feel queasy and wired at the same time.
Steep about 1 tablespoon (2 grams) of dried chamomile flowers in a cup of hot water for 5 to 10 minutes. The flavor is mild and slightly sweet, which makes it easier to drink when nothing else sounds appealing.
Fennel Tea: For Nausea From Bloating
When nausea is driven by indigestion, trapped gas, or a heavy, bloated feeling, fennel tea can help. Fennel contains compounds with anti-inflammatory properties that help relax digestive muscles, easing the pressure buildup that often produces that nauseated sensation after eating.
Add 1 teaspoon (2 grams) of dried fennel seeds to a cup of hot water, steep for 5 to 10 minutes, and strain. The taste is mildly sweet with a licorice-like flavor. It’s gentle enough to sip throughout the day.
Honey Lemon Tea: The Simplest Option
If you don’t have any herbs on hand, a simple combination of lemon juice and honey in hot water can ease mild nausea. The tartness of lemon can cut through that heavy, queasy feeling, while honey provides a small amount of easily digestible sugar that may help if low blood sugar is contributing to your symptoms. Mix 2 teaspoons of lemon juice and 2 teaspoons of honey into a cup of hot water. No steeping required.
Which Tea to Choose by Situation
- Morning sickness: Ginger tea is the first choice, with the strongest safety and efficacy data in pregnancy. Peppermint, chamomile, lemon, spearmint, and peach teas are also considered safe during pregnancy. One caution: peppermint essential oil (not tea) is not recommended during pregnancy because it can worsen reflux.
- Motion sickness: Ginger tea, ideally drunk 20 to 30 minutes before travel.
- Nausea after eating: Fennel or peppermint, both of which target bloating and digestive cramping.
- Stress or anxiety nausea: Chamomile for its calming effect.
- Chemotherapy-related nausea: Ginger has the most clinical support, but peppermint (even just the aroma) has shown benefit in studies as well.
Safety Considerations
Ginger can interact with blood-thinning medications like warfarin. Both ginger and warfarin independently affect bleeding risk, and combining them may increase the chance of unusual bleeding or bruising. If you take any anticoagulant medication, talk to your pharmacist or prescriber before drinking ginger tea regularly.
For most people, ginger tea in moderate amounts (under 5 grams of ginger per day) is safe. The most common side effects are mild: heartburn, burping, or loose stools. If ginger irritates your stomach, peppermint or chamomile are gentler alternatives that still offer real benefit.
