In short: Herbal teas such as chamomile, fennel, anise, ginger or peppermint are popular for stomach and gut complaints. Honestly, the evidence is thin: the US centre NCCIH sees no sufficiently reliable evidence for chamomile, and for peppermint oil, studies show benefits in irritable bowel but not as a tea. As a warm ritual and extra fluid, teas are still pleasant.
For many people, a warm tea after a meal is part of the feel-good routine. Here we take a close look at what tea can actually do for stomach and gut, and what is so far only tradition.
Which herbal teas are drunk for stomach and gut?
Most often it's chamomile, fennel, anise, caraway, peppermint, ginger and lemon balm that end up in the cup. Ready-made blends often combine several of these herbs.
| Herb | Traditionally used for | What does the evidence say? |
|---|---|---|
| Chamomile | stomach and gut, relaxation | according to NCCIH, not enough reliable evidence for individual complaints |
| Peppermint | digestion, irritable bowel | peppermint oil better than placebo for irritable bowel, tea not equally proven |
| Fennel and anise | bloating, feeling of fullness | traditional use, not specifically proven here |
| Ginger | nausea, stomach | often used, not specifically proven here |
The table sums up what we can back up from the sources we checked. Missing studies don't mean a tea does nothing, but they do mean claims should be read with caution.
What does science say about chamomile tea?
The NCCIH, an institute of the US health agency NIH, writes that studies on chamomile for various complaints have not delivered sufficiently reliable evidence. As a tea in usual amounts, chamomile is considered likely safe. Nausea, dizziness and allergic reactions are rare.
If you take medication, especially blood thinners or the pill, ask beforehand, as interactions have been reported. People with a known allergy to daisy-family plants should be especially careful.
Does peppermint tea help with stomach problems?
There are studies on peppermint oil: an analysis of 10 studies from 2022 found that peppermint oil improved symptoms and abdominal pain in irritable bowel more than placebo, though with more side effects such as heartburn. The result applies to peppermint oil and can't simply be transferred to tea.
The NCCIH also points out that peppermint oil on its own can harm some people with digestive problems. With heartburn, peppermint is therefore not always the best choice. More in our article Heartburn: What to Drink?
What's in frank.'s Happy Stomach Tea?
According to the product page, our Happy Stomach Tea contains linden blossom, anise, fennel, chamomile, ginger and sage. It costs €15. We don't claim it treats complaints; we see it as a soothing companion for your gut feeling after eating.
If you'd rather look for something to relax, the Organic Teas collection has other flavours like Calm Down Tea and Feel Good Tea.
How do you prepare stomach tea properly?
Pour freshly boiled water over 1 to 2 teaspoons and let it steep, covered, for about 7 to 10 minutes so the essential oils don't evaporate. Drink it unsweetened in small sips, ideally between meals or afterwards.
- Cover the cup while the tea steeps
- don't steep for longer than 10 minutes
- drink unsweetened
- two to three cups a day is a good framework
Which habits support the stomach as well?
Tea is one building block; habits are the foundation. If you eat slowly, chew thoroughly, don't eat meals too late in the evening and leave breaks between meals, you often do your stomach more good than with a new type of tea. Add high-fibre foods and enough fluid.
- Eat slowly and chew thoroughly
- Avoid large, heavy meals late in the evening
- Drink between meals, not just with them
- Move after eating, for example a short walk
- Increase fibre gradually
The NHS also describes how fibre and fluid work together: it recommends increasing fibre slowly and drinking plenty.
What's the bottom line?
Tea is not a medicine and doesn't need healing claims to earn a place in everyday life. A warm cup after a meal provides fluid, a pause and often a good gut feeling. The evidence on individual herbs is limited, so choose the tea you like and that does you good, and trust the basics: fibre, exercise, sleep and drinking enough.
For persistent or new symptoms, getting them checked comes before your next tea purchase.
Can you drink stomach tea every day?
For most people, one to two cups a day is unproblematic as long as there's no allergy. With long-term use of a single plant, variety makes sense, as does during pregnancy, breastfeeding and when taking medication, because some herbs are stronger than you'd think. If in doubt, ask your pharmacy.
When should you see a doctor about stomach and gut complaints?
If symptoms last more than a few days, recur or come with blood in the stool, weight loss, fever or severe pain. That also applies to sudden changes in digestion. The British NHS names blood in the stool, unintended weight loss and abdominal pain with constipation as reasons to see a doctor.
Tea can complement your routine but is no substitute for getting things checked. For ongoing complaints, you'll find background in our articles Constipation and Bloating.
