Chamomile is one of the most consumed herbal teas on the planet, and most people drinking it before bed couldn't tell you why it's supposed to help. It's just what you reach for when it's late, and coffee is obviously off the table. Two questions come up constantly: does it do anything for sleep, and does chamomile tea have caffeine in it?
Both have straightforward answers, and this covers them properly.

What is Chamomile Tea?
Chamomile tea is an infusion made from the dried chamomile flower. Two species are used commercially, and they're not quite interchangeable.
German chamomile (Matricaria chamomilla) is the more common one in tea bags and dried herb blends. It grows as an annual; the flowers are small and daisy-like with a hollow yellow centre, and the flavour is slightly sweet with an apple-ish note.
Roman chamomile (Chamaemelum nobile) is a perennial, lower-growing, and more often used in essential oils and topical preparations. The flavour is more bitter when brewed.
If a product just says "chamomile," it's almost certainly German. Most of the sleep research has used German chamomile or apigenin extracted from it.
The chamomile flower has one of the longest documented histories of any medicinal herb, with recorded use in ancient Egyptian, Greek and Roman medicine.
Does Chamomile Tea Have Caffeine?
No. Chamomile tea is naturally caffeine-free.
The reason is botanical. Caffeinated teas (black, green, white, oolong) all come from the same plant, Camellia sinensis. Chamomile doesn't. It's a herbal infusion made from flowers, not tea leaves, which means there's no caffeine present at any point in the process.
This makes it suitable for evening drinking, for people cutting caffeine, and for anyone sensitive to stimulants.
| Tea | Plant source | Caffeine per cup (approx.) |
|---|---|---|
| Chamomile | Chamomile flower | 0mg |
| Peppermint | Peppermint leaf | 0mg |
| Green tea | Camellia sinensis | 30–50mg |
| Black tea | Camellia sinensis | 40–70mg |
| Decaf black tea | Camellia sinensis | 2–5mg |
Decaffeinated black or green tea still contains trace caffeine. Chamomile contains none, because there was never any there to remove.
Does Chamomile Tea Help With Sleep?
The compound doing most of the work is apigenin, a flavonoid found in chamomile flowers.
Apigenin binds to benzodiazepine receptors in the brain, which are part of the GABA system. GABA is the body's primary inhibitory neurotransmitter, essentially the brake pedal for neural activity. When GABA signalling increases, mental activity quietens. This is the same broad pathway that anti-anxiety medications act on, though apigenin's effect is far milder and works differently in practice.
What the studies found:
A 2011 randomised controlled trial published in BMC Complementary and Alternative Medicine (Zick et al.) investigated chamomile extract in adults with primary insomnia. The study observed modest improvements in some daytime functioning measures, though it did not find statistically significant improvements in sleep latency or total sleep time compared to placebo.
Other research has been more favourable. A 2017 trial in older adults found chamomile extract was associated with improved sleep quality scores.
The evidence for chamomile and sleep is promising but not conclusive. Study sizes have generally been small, doses and preparations vary widely, and results are mixed. What the research consistently supports is that apigenin is biologically active in a way that's relevant to relaxation. What it doesn't support is a claim that chamomile tea treats insomnia.
There's also a behavioural component worth acknowledging. A warm drink, in a quiet room, 30 minutes before bed, is itself a sleep cue. Some of what people experience from chamomile is the ritual, and that's still something that many find helpful.
How to Use Chamomile Tea for Sleep
- Timing: 30 to 60 minutes before you want to be asleep. Any earlier and the wind-down effect fades; any later and you'll be up during the night.
- Brewing: this is where most people go wrong. Steep for 5 to 10 minutes and cover the cup. Chamomile's volatile oils, including the ones carrying apigenin, evaporate with the steam. An uncovered cup steeped for two minutes is a much weaker drink than the same tea covered for eight.
- How much: one to two cups per evening. More than that and you're mostly just drinking a lot of water before bed.
- Loose flower vs tea bags: dried whole chamomile flowers are generally higher quality and more potent than the cut-and-sifted material in standard tea bags. Look for whole or nearly whole flower heads with a strong sweet smell. Pale, dusty, fragmentary chamomile has usually been sitting around too long.
- Making it a ritual: add a small drizzle of honey if the flavour is too grassy for you. Drink it somewhere that isn't your desk. The consistency of the habit is doing as much work as the tea.
Other Benefits of Chamomile Tea
Digestive support
Chamomile has a long history of traditional use for digestive comfort, and research has explored its antispasmodic properties in relation to the gut. It's commonly used for occasional bloating and cramping.
Mild anxiety and stress
The same GABA-related mechanism relevant to sleep also applies during the day. A 2016 study in Phytomedicine explored long-term chamomile extract use in generalised anxiety disorder and observed reductions in symptom scores, though the researchers noted the need for larger trials.
Chamomile Tea vs Other Natural Sleep Supports
Different mechanisms, different problems.
| Support | Works on | Best for |
|---|---|---|
| Chamomile | GABA receptors (calming) | A mind that won't switch off |
| Tart cherry | Tryptophan (natural sleep pathways) | Trouble winding down at the right time |
| Lemon balm | GABA breakdown inhibition | Stress and mental restlessness |
| Magnesium | Muscle relaxation, GABA function | Physical tension, restless legs |
Most people don't have just one of these problems. A multi-ingredient approach tends to cover more ground than any single herb, which is why combined evening formulas exist at all.
Who Should Avoid Chamomile Tea?
- Ragweed and daisy family allergies: Chamomile is in the Asteraceae family alongside ragweed, daisies, marigolds and chrysanthemums. Cross-reactivity is documented, and reactions range from mild oral itching to more serious responses. If you react to any of these, speak to your GP before drinking chamomile.
- Pregnancy: Safety data during pregnancy is limited, and some traditional sources note uterine-stimulating properties. Consult your GP or midwife.
- Blood thinners: Chamomile contains coumarin compounds, and there's a theoretical interaction risk with warfarin and similar medications. The risk from normal tea consumption is low, but worth raising with your doctor if you're on anticoagulants.
- Before surgery: Because of the above, it's recommended to stop chamomile two weeks before scheduled surgery.
Chamomile Tea For Your Sleep Ritual
The chamomile flower is caffeine-free, cheap, widely available, and backed by a real, if imperfect body of research. It won't knock you out, and anyone promising that is overselling it. What it does offer is a mild calming effect through a documented mechanism, plus a warm ritual that signals to your body that the day is finished.
Give it two to three weeks of consistent use before deciding. Steep it covered, for long enough, and drink it at the same time each night.
If you'd rather have chamomile alongside other evening ingredients in one step, PurQ's natural sleep supplement combines chamomile with lemon balm, sour cherry, kiwifruit and Queen Garnet plum, which contributes anthocyanins alongside the calming botanicals. Explore the range at PurQ.
Frequently Asked Questions
Does chamomile tea have caffeine?
No. Chamomile tea is naturally caffeine-free because it's made from chamomile flowers, not from the Camellia sinensis plant that produces black, green and white teas. It's suitable for drinking in the evening.
How long does chamomile tea take to work for sleep?
Most people drink it 30 to 60 minutes before bed. The calming effect is gradual rather than immediate. Research protocols generally ran for two to four weeks, so consistent nightly use is more relevant than any single cup.
Can you drink chamomile tea every night?
For most healthy adults, yes. It's caffeine-free and non-habit forming. If you have a ragweed or daisy allergy, are pregnant, or take blood thinners, check with your GP first.
Is chamomile flower the same as chamomile tea?
Chamomile tea is made from dried chamomile flowers. Loose dried flowers and tea bags contain the same plant material, though whole flowers are generally higher quality and more potent than the finely cut material used in most commercial bags.
