Definition:
Passion flower is a herbal supplement used in the treatment of anxiety and sleep problems. The supplement is available in a number of forms, including infusions, teas, liquid extracts and tinctures. In general, passion flower is considered safe and nontoxic; however, because the Food and Drug Administration does not regulate the production of herbs and supplements, there is no guarantee about the ingredients or safety of the product. In addition, more rigorous scientific investigation is needed to make conclusions about the effectiveness of passion flower for the treatment of insomnia and anxiety disorders.
