Quick Answer: No, pure chamomile tea does not contain caffeine. A standard cup of 100% chamomile tea has 0 milligrams of caffeine because it's an herbal infusion made from dried chamomile flowers, not from the Camellia sinensis plant that produces caffeinated teas like black, green, and white tea. The main exception is blended teas that combine chamomile with actual tea leaves, so it's always worth checking the ingredient label.
Why Chamomile Tea Has No Caffeine
The reason comes down to botany. Black tea, green tea, white tea, and oolong all come from the same plant, Camellia sinensis, which naturally produces caffeine as part of its chemistry. Chamomile tea is different: it's made by steeping the dried flowers of the chamomile plant, which isn't related to the tea plant at all. In fact, chamomile is part of the Asteraceae family, the same botanical family as daisies, marigolds, and chrysanthemums, which is also why the flower itself resembles a small daisy.
Technically, chamomile tea isn't "tea" in the botanical sense. It's a tisane, an herbal infusion made from flowers, leaves, or roots of plants other than Camellia sinensis. Most tisanes, including peppermint, rooibos, and hibiscus, are naturally caffeine-free for the same reason. There are a few notable exceptions in the herbal tea world, though, yerba mate being the best known, which does naturally contain caffeine despite being an herbal infusion rather than a true tea. Chamomile isn't one of these exceptions; it contains no natural caffeine at all.
Roman vs. German Chamomile
Most chamomile tea on the market comes from one of two related but distinct plants, and neither contains caffeine:
- German chamomile (Matricaria chamomilla): The more widely used variety in commercial tea. It's an annual plant with a sweeter, more subtle flavor.
- Roman chamomile (Chamaemelum nobile): Sometimes called "true chamomile." It's a perennial plant with a bolder, slightly more bitter flavor profile.
Both varieties are used similarly, for tea, aromatherapy, and topical preparations, and the caffeine-free status applies equally to either one.
The Exception: Blended Chamomile Teas
Where things get less straightforward is with blended tea products. Some commercial tea bags marketed with "chamomile" in the name actually combine chamomile flowers with real tea leaves, green tea, black tea, or occasionally yerba mate, specifically to add caffeine to the blend.
This is why searches like "does Bigelow chamomile tea have caffeine" or "does Starbucks chamomile tea have caffeine" don't always have the same simple answer as pure chamomile. Most single-ingredient chamomile products from major brands are caffeine-free, but blends can vary. The only reliable way to know for certain is to check the ingredient list on the specific product you're drinking. If the only ingredient listed is chamomile flowers, it's caffeine-free. If it lists green tea, black tea, or "tea leaves" alongside chamomile, it will contain some caffeine.
Does Chamomile Tea Make You Sleepy?
Chamomile has a long history as a bedtime drink, and there's a plausible mechanism behind that reputation. Chamomile contains a compound called apigenin, which binds to certain receptors in the brain associated with reducing anxiety and promoting relaxation. Because it contains no caffeine, it also won't work against sleep the way caffeinated teas can.
That said, it's worth being accurate about the evidence here: research on chamomile specifically for insomnia has produced mixed and generally modest results, more consistent evidence supports a mild anxiety-reducing effect than a strong sleep-inducing one. It's reasonable to think of chamomile tea as a calming bedtime ritual rather than a proven sleep aid on its own.
Chamomile Tea vs. Green Tea
| Feature | Chamomile Tea | Green Tea |
|---|---|---|
| Caffeine content | 0 mg (pure chamomile) | Roughly 25 to 45 mg per cup |
| Plant source | Chamomile flower (not a true tea) | Camellia sinensis leaves |
| Best time to drink | Evening or before bed | Morning or daytime |
| Primary reputed benefit | Calming, mild anxiety reduction | Antioxidants, alertness |
Neither is objectively "better," they simply serve different purposes. Green tea suits people wanting a lighter caffeine option earlier in the day, while chamomile fits an evening wind-down routine specifically because it won't interfere with sleep.
Is Chamomile Tea Good for Kidneys?
Chamomile has a long history in traditional medicine as a remedy for kidney and bladder complaints, dating back to ancient Egyptian and Greek use. However, it's important to be honest about the modern evidence here: rigorous clinical research specifically on chamomile and kidney health is limited, and safety in people with existing liver or kidney disease hasn't been well established in clinical studies. If you have a diagnosed kidney condition, it's worth checking with a doctor before making chamomile tea a regular habit, rather than assuming traditional use translates to a proven modern benefit.
Who Should Avoid Chamomile Tea
Chamomile is well tolerated by most people, but a few groups should be cautious or avoid it:
- People with ragweed or daisy family allergies: Chamomile belongs to the Asteraceae (daisy) family, along with ragweed, chrysanthemums, and marigolds. People allergic to these plants have a higher risk of allergic reactions to chamomile, including rare but serious reactions.
- People on blood thinners or related medications: Chamomile may have mild blood-thinning properties and has been reported to interact with warfarin specifically. It may also interact with other antiplatelet drugs, NSAIDs like ibuprofen, and certain medications for organ transplant rejection (such as cyclosporine). Anyone on these medications should check with a doctor before drinking chamomile regularly.
- People taking sedating medications: Chamomile has mild calming properties and may add to the effects of sedatives, benzodiazepines, or other sleep or anti-anxiety medications.
- Pregnant individuals: Many health authorities advise avoiding regular chamomile use during pregnancy, since it may be associated with uterine contractions and there isn't enough safety data to confirm it's risk-free.
- People on hormone-sensitive medications: Chamomile may have mild estrogen-like effects. Some research suggests it could interact with birth control pills or affect hormone-sensitive conditions.
- Anyone scheduled for surgery: Due to its potential blood-thinning effect, it's commonly recommended to stop chamomile roughly two weeks before a surgical procedure.
- Anyone planning to drive: Because chamomile has mild sedative properties, some sources note it may cause drowsiness that's worth being aware of before getting behind the wheel.
None of this means chamomile tea is dangerous for the average healthy adult in normal amounts, it's one of the most widely consumed herbal teas worldwide. These are simply the groups where a conversation with a doctor is worthwhile first.
Frequently Asked Questions
Does chamomile tea have caffeine?
No. Pure chamomile tea contains 0 milligrams of caffeine because it's made from chamomile flowers, not the Camellia sinensis plant that produces caffeinated tea.
Does Starbucks chamomile tea have caffeine?
Starbucks' chamomile-based tea offerings are generally caffeine-free when chamomile is the sole tea ingredient, but it's worth checking the specific product, since blended options can differ. Checking the menu or asking directly is the most reliable way to confirm.
Can I drink chamomile tea in the morning?
Yes. Since it has no caffeine, chamomile tea won't provide an energizing effect, but there's no health reason it can't be enjoyed any time of day, not just before bed.
Does chamomile tea help you sleep?
It may support relaxation through a compound called apigenin, and its lack of caffeine makes it a sensible evening choice. However, scientific evidence for chamomile as a strong, standalone sleep aid is modest rather than conclusive.
Who should not drink chamomile tea?
People with ragweed or daisy family allergies, those on blood-thinning medication, pregnant individuals, and anyone with hormone-sensitive conditions should talk to a doctor before drinking chamomile regularly.
Which is better, chamomile or green tea?
Neither is universally better, they serve different purposes. Chamomile is caffeine-free and suited to evening relaxation, while green tea contains a moderate amount of caffeine and is better suited to daytime use.
Can you drink chamomile tea every day?
For most healthy adults, a cup or two of chamomile tea daily is generally considered safe. Long-term safety data is limited, though, so if you're drinking more than that regularly, or have an existing health condition, it's worth mentioning to a doctor.
Is there a caffeine-free herbal tea that still contains caffeine?
Yes, this sounds contradictory, but it's a common point of confusion. Most herbal teas (tisanes) are naturally caffeine-free, chamomile included. Yerba mate is a notable exception: despite being an herbal infusion rather than a true tea, it naturally contains a meaningful amount of caffeine.
