     Study: Passionflower in the treatment of generalized anxiety: a pilot double-blind randomized controlled trial with oxazepam
This study found that Passiflora extract and oxazepam, a benzodiazepine, were both effective in the treatment of generalised anxiety disorder, and no significant difference was observed between the two treatments at the trial’s end. Oxazepam acted quickly, with more problems found relating to job performance impairment in subjects. Passiflora extract was determined to be an effective drug for the management of generalised anxiety disorder, with low interference in a person’s work performance being an advantage. View study
