Apigenin, a flavonoid in chamomile, may promote sleep onset via benzodiazepine receptor binding
Apigenin binds to benzodiazepine receptors and enhances GABAergic activity, promoting sedation. While preclinical evidence is strong, human clinical trials are limited. Chamomile, a natural source, has shown modest sleep benefits.

Apigenin, a flavonoid in chamomile, may promote sleep onset via benzodiazepine receptor binding The current body of evidence comprises 1 study, including 1 randomized controlled trial. EvidenceHub rates the overall confidence at 62/100 (low).
The Claim
Apigenin, a flavonoid in chamomile, may promote sleep onset via benzodiazepine receptor binding
This conclusion is most relevant to: Adults with mild sleep complaints, Postpartum women.
How It Works
The proposed biological pathway:
- ▸Apigenin (flavonoid from chamomile)
- ▸Benzodiazepine receptor binding (positive allosteric modulator)
- ▸Enhanced GABA-A receptor activity
- ▸Increased chloride ion influx
- ▸Neuronal inhibition / sedation
- ▸Potential sleep onset promotion
Who Might Benefit
Evidence fit by population:
- ▸Adults with mild sleep complaints
- ▸Postpartum women
Recommended Dose
Varies (chamomile tea or extract)
Limitations & Caveats
Important context when interpreting this evidence:
- ▸Very limited human RCT data
- ▸Most evidence is preclinical (animal/in vitro)
- ▸No standardized dosing for isolated apigenin
- ▸Difficult to separate apigenin effects from other chamomile compounds
Frequently Asked Questions
Does chamomile tea help you sleep?▼
Chamomile contains apigenin, which binds to benzodiazepine receptors and may promote sleep. Human evidence is limited but suggests modest benefits, especially for postpartum women and those with mild sleep issues.
How much apigenin should I take for sleep?▼
There is no established dose for isolated apigenin. Drinking 1-2 cups of chamomile tea before bed is the most common approach. Apigenin supplements are available but dosing varies widely.
Is apigenin as strong as prescription sleep aids?▼
No. Apigenin's sedative effects are much milder than benzodiazepines or Z-drugs. It may be suitable as a gentle, non-habit-forming option for mild sleep issues.
