Passion Flower

Passion flower is a climbing vine native to the United States and Central and South America. It has been used for many years, as the chemicals within the vine have been shown to have calming, sleep-inducing, and muscle relaxation effects. Valerian root has been shown to have some similar effects.

A double-blind randomized controlled trial in the Journal of Clinical Pharmacology and Therapeutics compared passion flower to oxazepam, a benzodiazepine requiring prescription, and found that passion flower was an effective treatment for generalized anxiety. It was also found to have less sedating effects when compared to oxazepam, making it potentially safer for daytime use.

Another double-blind study found that passion flower combined with the prescription drug clonidine, had significantly more efficacy in treating opioid withdrawal than clonidine alone.

Another double-blind study found that passion flower effectively decreased anxiety in surgical patients.

Passion flower’s suggested benefit in after surgery recovery is in its ability to help reduce anxiety and offer a calming sensation, while also helping with muscle relaxation.*
