How it works

Passion flower is primarily used for reducing symptoms of generalized anxiety and improving sleep quality. Clinical trials suggest it may be as effective as some benzodiazepines for mild anxiety with fewer cognitive side effects.

It modulates the GABA system by increasing levels of gamma-aminobutyric acid in the brain, which promotes relaxation and reduces central nervous system activity.

Safety

  • May cause drowsiness, dizziness, or confusion.
  • Avoid during pregnancy as it may induce uterine contractions.
  • Discontinue 2 weeks before scheduled surgery due to potential CNS depression with anesthesia.
