Does chamomile tea help you sleep?

Verdict — Modest and mixed
Reviewed against the AntiAgingGreens evidence standard · Two randomised trials (mostly extract) · Last reviewed July 2026

A little — and the evidence is genuinely mixed. Some trials found chamomile improved self-reported sleep, but a rigorous placebo-controlled trial in people with insomnia found no clear effect on measured sleep, and most studies used chamomile extract, not the tea. It's a pleasant, low-risk bedtime ritual, not a proven sleep aid.

Elderly, extract capsules
Better self-reported sleep (unblinded, no placebo)
Insomnia, placebo-controlled
No significant change in measured sleep
The tea itself
Little direct evidence; a small, short-lived signal
Where the study design was weaker, chamomile looked helpful; in the most rigorous trial, it didn't move measured sleep. The honest read sits in between.

What the evidence supports

  • ✓ Better self-reported sleep quality in elderly taking chamomile capsules1
  • ✓ Hints of better daytime function and fatigue in insomnia (not significant)2
  • ✓ A low-risk, caffeine-free bedtime drink and wind-down ritual

What it doesn't mean

  • ✗ A proven sleep aid — the rigorous insomnia trial was null on measured sleep2
  • ✗ That the tea is what's tested — most trials used extract capsules
  • ✗ A treatment for insomnia, or a reason to take supplements

Where this comes from

What the human evidence shows
Two randomised trials frame the picture. In one, 77 nursing-home elderly took 400 mg of chamomile extract twice a day for four weeks and reported significantly better sleep quality than a control group.1 That's encouraging, but the study was unblinded with no placebo, so relaxation and expectation could explain much of it. In the more rigorous study — a double-blind, placebo-controlled trial in 34 adults with chronic insomnia taking chamomile extract for 28 days — there were no significant differences from placebo in sleep-diary measures (total sleep time, efficiency, how quickly people fell asleep, night-time waking), only small, non-significant hints on daytime function and fatigue.2
Tea versus extract
Note that both of those trials used chamomile extract in capsules — a supplement — not brewed tea. Direct evidence for chamomile tea is thin: a small study in new mothers found short-term improvements in sleep and mood that had faded a few weeks after they stopped. Broader reviews report improvements in self-rated sleep, but they pool tea with extract and rest on modest, subjective outcomes. So the cleaner statement is that chamomile has a weak, mixed signal, strongest for how people feel they slept rather than measured sleep.
Where the evidence stops — and why the tea can still help
Taken together, this is modest and uncertain, not a demonstrated treatment. But there's a genuine, separate reason a bedtime chamomile can help: a warm, caffeine-free drink as part of a calm wind-down routine supports sleep for many people, independent of the herb itself. That ritual is worth having. Chamomile tea is low-risk for most — the main caution is allergy, since it's in the daisy family — but we don't recommend chamomile supplements, and it's no substitute for sleep basics or, for lasting insomnia, cognitive behavioural therapy.

The practical version: if a mug of chamomile is part of a relaxing bedtime routine you enjoy, keep it — it's caffeine-free, low-risk and may help you wind down. Just don't count on the herb itself as a sleep cure, skip the chamomile capsules, and lean on the things that reliably move sleep: consistent timing, a cool dark room, less caffeine and alcohol, and CBT-I for ongoing insomnia. We recommend no supplement, and we sell nothing.

Bottom line for you

Chamomile tea is a lovely bedtime drink, but don't expect it to fix your sleep. The trials are small and pull in different directions — a weaker study in elderly people found better self-rated sleep, while a rigorous placebo-controlled trial in insomnia found no real change in measured sleep — and most tested chamomile extract, not the tea.

The honest takeaway: a warm, caffeine-free cup as part of a calm wind-down routine genuinely helps many people relax, and that's reason enough to enjoy it. Just treat any benefit as modest and uncertain, skip the chamomile capsules, and put your effort into the things that reliably improve sleep. We recommend no supplement, and we sell nothing.
