Passionflower

A worthwhile gentle anxiolytic herb with credible support, especially when tension or racing thoughts are the main issue.

A rough internal score reflecting quantity, quality, and consistency of human evidence. Not a clinical recommendation.

Human studies suggest passionflower can reduce anxiety and improve sleep quality, though many trials are small or use it as part of combination formulas.

• May reduce anxiety and mental agitation
• Often improves sleep quality
• Useful for stress-driven restlessness

Common use ranges from tea to 250-1000 mg/day of extract, often in the evening.

• Drowsiness
• Dizziness
• GI upset

Can cause drowsiness and should be used cautiously with sedatives, alcohol, or before driving.

A meaningful share of the literature uses multi-herb formulas, so the herb-specific effect is hard to isolate.
