Chamomile tea for sleep: small effect, real ritual
Chamomile tea for sleep produces modest improvements in sleep quality in trials, mostly in postpartum women and older adults. The bedtime routine may matter as much as the apigenin.

Key takeaways
- Chamomile contains apigenin, which binds benzodiazepine receptors weakly in laboratory models.
- Human trials show small improvements in self-reported sleep quality, not objective sleep time.
- People allergic to ragweed or on warfarin should check before regular use.
Chamomile is the most studied bedtime tea, which mostly tells you how little bedtime teas have been studied.
What is in it
The compound of interest is apigenin, a flavonoid that binds to benzodiazepine sites on the GABA-A receptor in vitro. The binding is weak, and how much apigenin crosses into the brain after a cup of tea is not well quantified.
What the trials show
A 2019 systematic review of 12 studies found small improvements in sleep quality scores, with the clearest effects in postpartum women and older adults in care settings. Objective measures, total sleep time, sleep efficiency on actigraphy, mostly did not move.
The ritual effect is not a dismissal
A warm, caffeine-free drink, dimmer lights and twenty minutes without a screen is a functioning wind-down routine. That the tea itself is a modest actor does not make the habit worthless, consistency of the pre-sleep cue is one of the better-supported behavioural levers.
Safety notes
- Allergy: chamomile is in the same family as ragweed, daisies and chrysanthemums
- Anticoagulants: chamomile has mild antiplatelet activity; check with a pharmacist if you take warfarin
- Pregnancy: high-dose extracts are not well studied; occasional tea is generally considered fine
If your sleep problem is chronic insomnia, cognitive behavioural therapy for insomnia outperforms every tea and most medications in head-to-head trials.
Frequently asked
How much should I drink?
Trials typically used one to two cups of strong infusion, or 200 to 400 mg of extract, in the hour before bed.
Does the liquid volume wake me up later?
It can. If you already wake to urinate, drink the tea 90 minutes before bed rather than at lights out.
