About

Passionflower is a climbing vine traditionally used as a calming herb in North and South American folk medicine. Research suggests its flavonoids, particularly chrysin, may support relaxation and sleep by interacting with GABA receptors in the brain.

How It Works

Chrysin and other flavonoids bind GABA-A receptors (benzodiazepine site); increases total GABA levels.
