This extract concentrates the above-ground parts of *Passiflora incarnata*, standardizing to flavonoids (often 2-3%). Compared to raw herb or tea, it delivers more potency per dose, so typical serving sizes are smaller. Many choose extracts for convenience and reliable potency, but absorption comparisons with other forms remain limited.
People use this extract to promote calmness and ease occasional stress. Many take it before bed to encourage relaxation and support sleep onset. Tablets, capsules, and liquid drops are common forms, often taken in the evening or 30-60 minutes before sleep. A meal can help reduce stomach upset for sensitive individuals.
Do not drive or operate machinery until you know how passionflower affects you, as it can cause drowsiness. Avoid during pregnancy due to theoretical concerns about uterotonic effects, although evidence is weak. Talk to a healthcare professional before combining with sedatives or central nervous system depressants (for example, benzodiazepines, alcohol) because additive drowsiness may occur.
