What is it? / Overview
Passionflower appears to influence GABA neurotransmission producing mild anxiolytic effects. Human studies suggest it may reduce situational anxiety with relatively few adverse effects though evidence is less robust than for conventional anxiety treatments.
How is it used? / Administration
Form: Standardized Passiflora incarnata extract
Typical dose studied: 250–500 mg/day
Timing: Evening or 30–60 min before anxiety-provoking situations
Best evidence for mild or situational anxiety. May cause drowsiness — avoid driving until individual effects known.
How well does it work? / Evidence
? Emerging / limited evidence
Who should avoid it?
Avoid with: Breastfeeding
Interacts with: Sedatives; Benzodiazepines; Alcohol
Already taking it? Avoid combining with multiple sedating supplements without medical guidance. Traditionally avoided in pregnancy due to potential uterine stimulation -- worth stating plainly even though the platform's own intake flow already hard-blocks recommendation generation for anyone reporting current pregnancy.
