Quick Take

Direct human evidence is limited; may help sleep and relaxation, but most support comes from chamomile trials.

Apigenin is a flavone found in chamomile, parsley, celery, and some citrus fruits. It may calm the nervous system by modulating GABA_A signaling and shows anti-inflammatory activity in lab studies. The best human evidence comes from chamomile extract trials, which suggest modest benefits for sleep quality and anxiety. It is most relevant for people with mild sleep problems or stress who want a non-prescription calming aid.

How It Works

Apigenin can cross the blood-brain barrier and modestly modulate GABA_A receptors, including the benzodiazepine binding site, which may reduce neural excitability. In lab studies it also inhibits NF-κB and COX-2 signaling, producing anti-inflammatory effects that are not yet well proven in humans.
