Peppermint tea is a naturally caffeine-free herbal tea made by steeping the leaves of Mentha x piperita in hot water. It is valued for its cooling menthol aroma, its crisp minty taste, and the fact that it carries no caffeine and virtually no calories.
Despite the name, it is not a true tea at all. True teas - green tea, black tea, oolong, white - all come from Camellia sinensis. Peppermint is a herbal infusion, which is exactly why it has no caffeine to begin with rather than having had it removed.
This guide covers what is in the cup, how to brew it properly, who should be careful with it, and - the part most articles skip - what the research does and does not actually show.
What Is Peppermint Tea?
Peppermint tea is derived from the peppermint plant, a natural hybrid of watermint and spearmint. It is made by steeping peppermint leaves, either fresh leaves or dried, in hot water. This releases the essential oil that gives the drink its minty aroma and flavour. The pleasant smell of a fresh cup of peppermint tea comes almost entirely from that oil, whose main constituent is menthol.
Peppermint naturally contains aromatic compounds - menthol above all, alongside menthone - and menthol is what produces the signature cooling sensation and crisp minty taste. The leaf also holds rosmarinic acid, which is not volatile and contributes nothing to the cooling effect. The same compounds appear in peppermint extract and peppermint oil, but in brewed tea they are present in a far milder concentration. That difference matters more than almost anything else on this page, and it comes up again below.
Because pure peppermint tea contains no caffeine, it can be enjoyed at any hour. Browse our peppermint tea collection to compare formats, flavours and blends.
Caffeine: How It Compares
Peppermint tea has no caffeine whatsoever. Not "low" - none, because the peppermint plant never contained any. Here is how a cup sits against the usual alternatives.
| Drink (8 oz) | Approximate caffeine |
|---|---|
| Peppermint tea | 0 mg |
| Green tea | 20-45 mg |
| Black tea | 40-70 mg |
| Brewed coffee | ~95 mg |
That is the whole reason peppermint turns up in evening routines and in the cupboards of people cutting back. If you are comparing caffeine-free options more broadly, our guide to herbal tea and caffeine covers which herbal infusions genuinely contain none.
How to Brew Peppermint Tea
Peppermint is one of the more forgiving infusions. It carries far fewer tannins than a true tea, so a long steep will not punish you the way it would with green tea.
- Leaf: 1 tea bag, or 1-2 tsp of dried peppermint, per 8 oz cup
- Water: just-boiled, straight off the kettle
- Time: 5-10 minutes, covered so the aromatic oils stay in the cup rather than leaving with the steam
Covering the cup while it steeps is the single tip most worth taking away: menthol is volatile, and an uncovered mug loses a noticeable amount of the aroma you are brewing for.
Fresh leaves work too. Use a generous handful, and tear the leaves lightly before they go in - torn peppermint leaves release their oils faster than whole ones. Peppermint also cold brews well: leave the leaf in cold water in the fridge for a few hours for a crisper, gentler infusion.
Formats: Loose Leaf, Bags and Organic
Peppermint tea comes as loose leaf tea, in tea bags, and in organic versions. Loose-leaf gives a fresher, more aromatic cup, since the leaf is larger and less broken; peppermint tea bags trade a little of that for convenience. Organic peppermint tea appeals to shoppers who prefer herbs grown without synthetic pesticides or fertilisers, and we carry those in our organic range.
Dried peppermint is easy to find in grocery stores, but quality varies a great deal - a pale, dusty leaf has usually lost most of its oil. Look for leaf that is still green and smells sharp through the bag.
Some people blend peppermint with other herbal teas to build a new flavour profile while keeping peppermint's cooling character. If you want similar caffeine-free options, spearmint, chamomile and lemon balm are the usual neighbours - each with its own profile. Our roundup of the best peppermint teas compares specific blends, and the flavour guide goes deeper on taste.

What Is Actually in the Cup
Peppermint tea contains aromatic compounds, chiefly menthol, along with menthone and rosmarinic acid. The term you will meet in the literature is muscle relaxant: it describes what concentrated peppermint oil was studied for in gastrointestinal trials, and it is not a property we would attach to a mug of tea. It also contains naturally occurring plant compounds with antioxidant activity; some research has examined antioxidant activity in peppermint compounds, though brewed tea is best viewed as a mild dietary beverage rather than a concentrated source.
Nutritionally it is close to nothing: naturally calorie free in practice, a plain cup of peppermint tea is typically 0-5 calories with under a gram of carbohydrate, no sugar and no sodium, provided you do not sweeten it. That is the basis of the one genuinely uncontroversial practical point on this page - swapping a 12 oz sugary soft drink for unsweetened peppermint tea removes roughly 140 calories and about 39 grams of sugar from the day.
What the Research Does and Does Not Show
Peppermint has been studied a great deal, and almost every popular claim you will read traces back to a study on peppermint oil capsules or topical oil rather than on a brewed cup. The two are not interchangeable: enteric-coated oil delivers a concentrated dose to the gut, while a mug of tea delivers a small fraction of the same compounds to a very different place. We think it is worth being specific about which is which.
- Digestive comfort and IBS symptoms. A 2014 systematic review and meta-analysis in the Journal of Clinical Gastroenterology pooled nine trials covering 726 patients and found enteric-coated peppermint oil significantly better than placebo for global IBS symptoms and for abdominal pain. That evidence is for the capsules. Brewed tea is a much milder product, and it has not been shown to do the same thing. Many people find a warm cup after a meal comfortable; that is a fair description, and treating persistent abdominal pain is not.
- Tension headaches. The research here involves peppermint oil applied to the skin, not tea. A warm, cooling-smelling drink may feel pleasant during a headache. It is not headache treatment, and headaches that are severe, frequent, unusual or accompanied by other symptoms need a doctor, not a teapot.
- Breath. In one often-cited study, students using a peppermint mouth rinse had better breath after a week than a control group. A rinse is not a tea. Peppermint tea leaves a fresh, minty sensation in the mouth; it does not replace brushing, flossing or dental care.
- Congestion. Simply inhaling the steam can make breathing feel clearer, and any warm liquid can feel soothing on a sore throat. Neither is decongestion, and peppermint tea does not kill viruses or shorten a cold.
- Weight. Some studies suggest peppermint oil capsules may affect appetite. Again: capsules. What peppermint tea genuinely offers here is arithmetic, not pharmacology - it is a zero-calorie drink that can take the place of a sweetened one.
Because so much of what circulates about this drink is second-hand, here is the claim landscape in one place. The left column is what people search for; the right is what the evidence actually involves.
| Popular claim | What is actually behind it |
|---|---|
| Supports digestive health, aids digestion, eases gas | Trials of enteric-coated oil capsules, not tea. Peppermint tea does not treat the digestive system. |
| Relieves IBS symptoms and abdominal pain | The 2014 meta-analysis below - again, capsules. Brewed tea has not been shown to do this. |
| Headache relief, eases headache symptoms | Studies applied peppermint oil to the skin. Peppermint tea is not headache treatment. |
| Clears clogged sinuses, decongestant | Menthol changes how airflow feels. Peppermint tea does not decongest and does not shorten a cold. |
| Fights bad breath and dental plaque | A mouth-rinse study. Peppermint tea gives fresher breath as a sensation only; it does not replace dental care. |
| Antibacterial properties against harmful bacteria | Laboratory work on extracts. Antibacterial activity in a petri dish is not an effect in a person drinking tea. |
| Helps you lose weight, weight management goals | Appetite work used capsules. The tea's only real contribution is that it is calorie-free. |
| Improves sleep quality, calms anxiety | No good evidence. It is caffeine-free, which is a different and much more modest thing. |
| Eases menstrual cramps, lowers blood pressure, improves brain function, clears kidney stones | Nothing we would stand behind. Some rest on animal studies, some on nothing at all. |
None of this makes peppermint tea less worth drinking. It makes it a drink rather than a remedy, which is how we would rather sell it. Where research suggests something real, it is nearly always about a concentrated product that is not in your mug.
More research is needed on nearly all of it, and much of the existing work is laboratory or animal studies rather than trials in people consuming peppermint tea. We sell tea, so we would rather tell you that plainly than repeat the health benefits of peppermint that we cannot stand behind. If you came here looking for the benefits of peppermint tea, the honest list is short: no caffeine, no calories, and a cup you enjoy.
How It Fits Into a Daily Routine
Peppermint tea is easy to work into the day precisely because it asks so little. Many people have a cup after meals, when its cooling aroma and clean finish feel appropriate. Others keep it for the evening, since it adds no caffeine to a routine that is winding down.
Its crisp, refreshing flavour makes it a straightforward alternative to sugary drinks, and it contributes to daily fluid intake. For anyone cutting back on sweetened beverages, that is a simple and durable swap - and the reason peppermint sits in so many kitchens as an everyday caffeine free tea. As a caffeine free beverage it asks nothing of your evening, which is more than most drinks can say.
Who Should Avoid or Limit It
Peppermint tea is well tolerated by most people, but it is not for everyone.
Peppermint is commonly listed among the things to be careful with if you have acid reflux, GERD, frequent heartburn or a hiatal hernia, because it can relax the sphincter between the stomach and the oesophagus and in some individuals that makes reflux worse rather than better. Whether that applies to you is a question for your clinician, not for us. It is the best-known caution, though not the only one.
Some people are sensitive or allergic to peppermint, so allergic reactions, though uncommon, are worth watching for. How much suits you is individual, and drinking too much peppermint tea may simply cause discomfort, so moderation is sensible. We are a tea shop and do not give intake guidance; if you want a number for your own circumstances, that question is for a clinician. If you are pregnant, taking medication, or managing a health condition, ask a professional who knows your situation rather than a tea shop.

Frequently Asked Questions
What happens if I drink peppermint tea every day?
For most people, very little beyond enjoying it. It is caffeine-free and essentially calorie-free, so a daily cup fits easily into an after-meal or evening routine. How much is right for you depends on your own tolerance, and that is not something we can answer for you.
Will peppermint tea flatten your stomach?
No. Peppermint tea is not a weight loss product and does not burn fat. Some people find a warm cup after a meal comfortable, but a temporary lighter feeling is not fat loss. Its only real contribution to weight management is that it can replace a higher-calorie drink.
When should you not drink peppermint tea?
The caution that comes up most often concerns acid reflux and GERD: peppermint can relax the lower oesophageal sphincter, which in some individuals worsens symptoms. Peppermint sensitivity, though uncommon, also exists. Whether either applies to you is a question for a clinician rather than a tea shop.
Does peppermint tea have caffeine?
No. Peppermint tea contains no caffeine at all, because peppermint is a herb rather than a true tea from the Camellia sinensis plant.
Is peppermint tea good for digestion?
Many people drink it after meals and find it comfortable. The stronger digestive evidence, though, is for enteric-coated peppermint oil capsules rather than brewed tea, so it is fairer to describe the tea as a pleasant after-meal drink than as a digestive remedy.
How long should you steep peppermint tea?
Five to ten minutes in just-boiled water, covered. Peppermint has far less tannin than a true tea, so a longer steep gives a stronger cup rather than a harsh one.
Final Notes
Peppermint tea is a simple, refreshing herbal tea that fits into a balanced daily beverage routine - after meals, in the evening, or in place of something sweeter. It carries no caffeine, next to no calories, and a cooling character that few other herbs match.
