It contains flavonoids and alkaloids believed to modulate GABA activity in the brain, which may promote relaxation and reduce anxiety. Passion flower is often consumed as tea, tincture, or capsules.
Commonly taken for stress, sleep, and nervous tension, passion flower shows mild sedative effects in some studies. More rigorous clinical trials are needed to better define its effectiveness and dosing.

Studies
These studies provide scientific insights into Passion Flower benefits:
A 1998 double‐blind RCT in 80 generalized anxiety disorder patients demonstrated that 260 mg/day Passion Flower extract reduced HAM‐A scores by 13.9 points versus 12.1 with oxazepam (10 mg/day) over 4 weeks (P > 0.05), suggesting comparable anxiolytic efficacy with fewer sedative effects.
A 2002 pilot study found 500 mg Passion Flower twice daily for 2 weeks did not significantly alter EEG sleep parameters or subjective sleep quality versus placebo in healthy volunteers (ns).
A 2022 systematic review of five small RCTs concluded that while Passion Flower may offer mild anxiolytic benefits, evidence certainty is low due to small samples and heterogeneous methodologies.
Despite in vitro GABAergic activity, no large‐scale RCTs have evaluated Passion Flower for insomnia or menopausal mood disturbances.
