Tea for Headache: Which Tea Is Best, and How Many Cups of Chai Cross the Caffeine Line
Looking for the right tea for headache relief is a very Indian instinct. We reach for the kettle before the medicine box.
This page has been rebuilt from the original studies. Every number below comes from a trial, a guideline, or the international headache classification.
Short answer. Ginger has the best evidence. It is still modest: people were 1.79 times more likely to be pain-free at two hours. Peppermint works as an oil on your temples, not as a drink. Your chai is mostly a caffeine question. A strong cup carries 65 mg, so four of them cross the 200 mg withdrawal line.
The five things worth knowing
- Ginger helped during an attack and failed at preventing attacks.
- The famous peppermint result used 10% oil rubbed on the forehead, not tea.
- Caffeine needs 100 mg or more, alongside a painkiller, to do measurable work.
- An Indian 150 ml cup of tea is 30 to 65 mg of caffeine.
- Skipping your usual chai can start a headache within 24 hours.

Which tea is best for a headache?
Ginger tea is the best-supported choice, and the support is modest. Pool three randomised trials. People given ginger were 1.79 times more likely to be pain-free at two hours. The same analysis found no clear effect on overall treatment response. Nothing else on the tea shelf has trial evidence this strong.
Headaches are not a small Indian problem. A door-to-door survey in Karnataka covered 2,329 adults.
In one year, 63.9% of them had a headache. That is nearly two in every three people.
Migraine alone came in at 25.2%, against a global average near 14.7%. Tension-type headache reached 35.1%.
So the question is worth answering properly. Most pages about tea and headaches list five herbs and imply all five work.
That is not what the research says. One has real evidence for an attack in progress.
One has evidence in the wrong form. The rest have none at all.
Does chai help a headache, or cause one?
Your chai is a caffeine dose first and a comfort second. ICMR-NIN puts a 150 ml Indian cup of tea at 30 to 65 mg of caffeine. The headache classification is just as exact. A caffeine-withdrawal headache follows regular intake above 200 mg a day for over two weeks. It starts once you stop or delay that dose.
Nobody publishes that multiplication, so here it is. The weak column uses a 30 mg cup and the strong column 65 mg.
| Cups of chai a day | Weak cup | Strong cup | Where that lands |
|---|---|---|---|
| 1 | 30 mg | 65 mg | under both limits |
| 2 | 60 mg | 130 mg | under both limits |
| 3 | 90 mg | 195 mg | under both limits |
| 4 | 120 mg | 260 mg | a strong cup is past 200 mg |
| 5 | 150 mg | 325 mg | a strong cup is past 300 mg |
| 6 | 180 mg | 390 mg | a strong cup is past 300 mg |
| 7 | 210 mg | 455 mg | both ends past 200 mg |
Read the fourth row again. Four strong cups is 260 mg, already past the 200 mg line.
If your chai is light, you have more room. You would need about 7 weak cups to get there.
The same guideline sets a wider ceiling. It asks you to keep total caffeine under 300 mg a day.
That is roughly 5 strong cups. Or about 10 weak ones, before any coffee.
Here is the practical bit. On a headache day, keep your normal chai at your normal time.
Skipping it is the riskier move. Withdrawal shows up within 24 hours of your last dose.
It settles within seven days if you stay off caffeine. Most people would rather just have the chai.
One more thing the guideline says about chai. Tannins in tea block iron absorption.
So leave an hour either side of a meal. That single habit is worth more than most tea advice.

Shop NowHeadache: tea or coffee?
Coffee, if you want caffeine to do actual work. A Cochrane review pooled 20 studies. Caffeine at 100 mg or more was taken with a normal dose of paracetamol or ibuprofen. That let 5% to 10% more people reach good pain relief. A 150 ml cup of brewed coffee carries 80 to 120 mg. An Indian cup of tea carries 30 to 65 mg, usually under the dose.
This is the detail almost every article misses. The caffeine research is about caffeine added to a painkiller.
It is not about caffeine on its own. That is why headache tablets often list caffeine on the label.
The effect is also small. The number needed to treat was about 14.
So roughly one extra person in fourteen does better. That is real, and it is not dramatic.
Set against that, tea has one clear advantage. At 30 to 65 mg a cup, it is harder to overshoot.
Ginger tea: the best evidence, and where it failed
Ginger helps during an attack and does nothing to prevent one. A 100-person trial found ginger powder statistically comparable to sumatriptan at two hours. Its side effects were fewer too. Then 107 people took 200 mg of ginger extract, three times a day, for three months. It did no better than placebo at preventing migraines.
Start with the good news, because it is genuinely good. Ginger is the only tea ingredient here with randomised trials behind it.
The pooled result was a 1.79 times higher chance of being pain-free at two hours. Pain scores also fell further with ginger than with placebo.
Nausea and vomiting were lower too. For a migraine, that matters as much as the pain.
Now the three honest limits. First, the trials used ginger powder and extract capsules, never a brewed cup.
A strong cup of fresh ginger tea is not the same product. Nobody has measured how the two compare.
Second, the emergency-room trial gave 400 mg of ginger extract alongside 100 mg of intravenous ketoprofen. Ginger was the addition, not the treatment.
Third, ginger failed the prevention test outright. The authors wrote that it gave no greater benefit than placebo as a preventive.
So drink ginger tea when your head already hurts. Do not drink it every morning hoping the attacks stop.

Peppermint: oil on your temples, not tea in your cup
The peppermint result everyone quotes is about skin, not sipping. One crossover study covered 41 people and 164 tension headaches. A 10% peppermint oil solution, spread on the forehead and temples, cut headache intensity from 15 minutes onward. It matched 1,000 mg of paracetamol. No trial shows the same for drinking peppermint tea.
The oil was reapplied at 15 and 30 minutes. Patients reported no side effects.
You cannot reach that concentration in a cup. A brewed infusion is mostly water.
That does not make peppermint tea useless. It is caffeine-free, warm, and pleasant to breathe.
Just call it what it is. It is comfort, and comfort has value on a bad day.
If you want the oil route, buy a plain peppermint essential oil on Amazon and dilute it before it touches skin. We do not sell essential oils, so that is an affiliate link.
Our peppermint oil guide goes into the aroma research in detail, and peppermint oil for focus covers the alertness claims.
Black tea and green tea
Black and green tea are small, steady caffeine doses. Neither has a trial showing it treats a headache. What they do well is hold your caffeine level steady, which is what stops a withdrawal headache from starting.
People search for black tea and headaches in two opposite moods. Some want relief, and some suspect the tea caused it.
Both can be right on different days. The deciding factor is not the leaf, it is the dose and the routine.
Drink your normal amount and you are fine. Double it, or skip it, and your head will notice.
The guideline adds one note about milk. Tea's flavonoid benefits are best obtained when milk is not added and the tea is taken in moderation.
For everything else green tea does, see green tea benefits, and how to brew green tea for temperature.
Matcha is a stronger dose again, because you swallow the whole leaf. Our matcha caffeine guide carries those numbers.
What tea is good for tension headaches?
For tension headache, the tested thing is peppermint oil on the skin. No tea has trial evidence for this type. Tension-type headache is also the most common kind in India, at 35.1% of adults in a year.
A caffeine-free cup still earns its place. It gets you to sit down for ten minutes.
Chamomile, tulsi and plain peppermint all fit. None of them will keep you awake later.
Browse caffeine-free herbal teas for options, or tulsi tea benefits if holy basil is already in your kitchen.
Which tea is best for migraine?
Ginger, and only during an attack. Trials found ginger helped at two hours and failed as a preventive. Tea is never a replacement for a prescribed migraine treatment.
Migraine is common here. One in four adults in the Karnataka survey met the criteria.
That is well above the global average. It is also a reason to see a doctor rather than self-treat for years.
If ginger helps you, use it the way the trials did. Take it when the attack starts, not as a daily ritual.
Teas to leave alone when your head hurts
Two to watch: licorice and any very strong brew. Products supplying 100 mg or more of glycyrrhizic acid a day raised systolic blood pressure by 5.45 mmHg across 18 studies, and lowered plasma potassium. A second review of 8 trials found the same direction, about 3.48 mmHg systolic.
Licorice is mulethi, and it turns up in cough mixtures and herbal blends. It is a blood-pressure issue, not a headache cure.
The effect follows the dose. The reviewers noted a rise even at modest intakes.
Interestingly, the same 2024 review found no effect from licorice flavonoid products. The trouble is the glycyrrhizic acid specifically.
If you already manage hypertension, skip it and keep a home blood pressure monitor handy. Our tea and blood pressure page has the fuller picture.
The second thing to avoid is an unusually strong pot. It is the fastest way to push past 200 mg without noticing.
Willow bark deserves a line too. It is the plant aspirin came from, and we found no randomised trial of it for headache.
Treat it like aspirin anyway. Avoid it with an aspirin allergy, in pregnancy, on blood thinners, and in children.
Does drinking more water fix a headache?
It helps you feel better without cutting headache days. In a trial of 102 people with recurrent headaches, drinking an extra 1.5 litres a day improved migraine-specific quality of life by 4.5 points, and 47% reported much improvement against 25% in the control group. Days with at least moderate headache did not change.
That is a more honest result than the usual advice. Water made people feel better without removing the headaches.
A cup of tea is also water. On a hot Indian afternoon, that matters more than the leaf you chose.
Our daily water intake guide works out what your body actually needs.
When the tea is not the problem
Sometimes the painkiller is causing the headache. The classification defines medication-overuse headache as headache on 15 or more days a month, in someone with an existing headache disorder, from regular overuse of acute medication for more than three months. In the Karnataka survey, 1.2% of adults met the probable criteria.
That is a small percentage of a very large country. It is also completely fixable, once someone spots it.
The threshold depends on the drug. It is 10 or more days a month for some, and 15 or more for others.
If you are taking something for your head most weeks, that is the conversation to have with a doctor. No tea solves this one.
How to brew a ginger and peppermint infusion
Ginger for the evidence, peppermint for the steam and the taste. This is the cup the cover photo shows.
- Slice a 2-inch piece of fresh ginger into thin coins. Thin beats thick, because surface area does the work.
- Add a small handful of fresh peppermint leaves, around 8 to 10.
- Load both into a steel mesh infuser basket.
- Pour water at about 95 °C over them.
- Steep 8 to 10 minutes. Ginger is slower than tea leaves.
- Breathe the steam before the first sip, then drink it slowly.
Add lemon if the raw ginger bite is too sharp. Add nothing else.
A glass press pot makes this easy to see and easy to clean. New to loose leaf? Our tea infuser guide covers the basics.

Frequently asked questions
Which tea is best for headache?
Ginger tea has the best evidence, and it is still modest. A meta-analysis of three trials found people were 1.79 times more likely to be pain-free two hours after ginger. Those trials used ginger powder and extract capsules, not a brewed cup.
Kya chai peene se sar dard theek hota hai?
Sometimes, and sometimes chai is the cause. One cup of Indian tea carries 30 to 65 mg of caffeine. That is usually below the 100 mg dose that helps a painkiller work, and drinking four or more strong cups daily can set you up for a withdrawal headache.
Sar dard me chai peena chahiye ya nahi?
Have your usual cup, at your usual time. Skipping it is riskier than drinking it, because missing your regular caffeine can start a headache within 24 hours.
Headache - tea or coffee?
Coffee, if you want caffeine to do real work. A 150 ml cup of brewed coffee carries 80 to 120 mg and tea only 30 to 65 mg. The pain research only found a benefit at 100 mg or more, and only when caffeine was taken with a painkiller.
Is black tea good for a headache?
Black tea is a small dose of caffeine in hot water. It can take a mild edge off, mostly by keeping your usual caffeine level steady. It is not a treatment, and a very strong pot can push your daily total past the 200 mg dependency line.
Does green tea help or hurt headaches?
Both are possible. A cup keeps your caffeine level steady, which prevents a withdrawal headache. Drink far more than usual, or suddenly stop, and green tea becomes part of the problem.
Which tea is best for migraine?
Ginger, on the evidence we have. It helped during an attack in the trials, and it clearly failed at preventing attacks. Do not swap your prescribed migraine treatment for a cup of tea.
What tea is good for tension headaches?
For tension headache, the tested thing is peppermint oil rubbed on the forehead and temples, not peppermint tea. A caffeine-free cup still helps you rest, and the warm steam is pleasant.
Does peppermint tea help with headaches?
There is no trial showing that drinking it does. The trial that worked used a 10% oil solution applied to the skin. Drinking the tea is comfort, not medicine.
Can too much tea cause headaches?
Yes. The headache classification defines a caffeine-withdrawal headache after more than 200 mg a day for over two weeks, once you stop or delay your dose. Four strong Indian cups a day already reach that level.
Should I avoid licorice or mulethi tea if I get headaches?
Be careful if your blood pressure is high. Products with 100 mg or more of glycyrrhizic acid a day raised systolic pressure by about 5.45 mmHg in a meta-analysis of 18 studies.
How many cups of chai a day is too much?
By the Indian guideline, keep total caffeine under 300 mg a day. That is about five strong cups, or around ten weak ones, before you add any coffee.
