Every “best sleep tea” list starts with chamomile. The reason has a name: apigenin.
What is apigenin?
Apigenin is a naturally occurring flavonoid concentrated in chamomile flowers. It’s the compound most cited when researchers study why chamomile is associated with calm and sleepiness.
How is it thought to work?
Studies suggest apigenin can bind to the same receptor family in the brain that calming medications target — far more gently. That’s why a strong chamomile cup is relaxing rather than sedating: support, not a switch.
How do I get a stronger cup?
Whole flowers (not dust), a full teaspoon, water just off the boil, steeped covered for 5–7 minutes. Covering matters — it keeps the volatile compounds in the cup instead of the air.
Quick facts
• Apigenin occurs in chamomile, parsley and celery — chamomile tea is its most famous source.
• Whole dried chamomile keeps more potency than crushed teabag dust.
