Overview
Passionflower is native to the southeastern United States and was used by Native Americans for its calming properties long before European contact. Spanish explorers named it after the Passion of Christ, seeing religious symbolism in its intricate flower structure.
Unlike stronger sedatives, passionflower works gently to calm nervous tension without causing heavy sedation. It is particularly helpful for the type of anxiety that manifests as racing thoughts, making it useful for both daytime anxiety and sleep disturbances caused by an overactive mind.
How It Works
Passionflower increases levels of GABA in the brain by inhibiting its breakdown. This is similar to how benzodiazepines work, but passionflower's effect is much gentler and does not carry the same risks of dependence.
The flavonoids in passionflower, particularly chrysin, appear to bind to benzodiazepine receptors in the brain, contributing to its calming effects. Unlike synthetic sedatives, passionflower contains multiple compounds that work together, which may explain its gentler action.
What It's Used For

Clinical studies show effectiveness comparable to some anti-anxiety medications for generalized anxiety. Works without sedation at moderate doses.
