Passion flower is native to the southeastern United States and Central and South America. It's been traditionally used to help with sleep.
People use passion flower for anxiety, including anxiety before surgery. Some people also take passion flower for insomnia, stress, ADHD, pain, and many other conditions. But there is no good scientific evidence to support these uses. In some foods and beverages, passion flower is added for flavoring.
Uses & Effectiveness ?
Possibly Effective for
- Anxiety. Taking passion flower by mouth can reduce symptoms of anxiety. It might work as well as some prescription medications.
- Anxiety before surgery. Taking passion flower by mouth can reduce anxiety when taken 30-90 minutes before surgery. In fact, it might work as well as some other treatments for anxiety before surgery, such as melatonin or midazolam. But it might also interact with some anesthesia drugs, so don't use passion flower before surgery unless recommended by a healthcare provider.
When applied to the skin: There isn't enough reliable information to know if passion flower is safe or what the side effects might be.
Special Precautions and Warnings
Breast-feeding: There isn't enough reliable information to know if passion flower is safe to use when breast-feeding. Stay on the safe side and avoid use.
Children: Passion flower is possibly safe for most children when taken by mouth for short periods of time. A specific passion flower product (Pasipay by Iran Darouk Pharmaceutical Company) has been used safely in children aged 6-13 years for up to 8 weeks.
Surgery: Passion flower might slow down the nervous system. Anesthesia and other medications used before and after surgery can also slow down the nervous system. Taking them together might slow down the nervous system too much. Talk to your healthcare provider if you are taking passion flower within 2 weeks of a scheduled surgery.
Sedative medications (CNS depressants) interacts with PASSIONFLOWER
Passionflower might cause sleepiness and drowsiness. Medications that cause sleepiness are called sedatives. Taking passionflower along with sedative medications might cause too much sleepiness.
Some sedative medications include pentobarbital (Nembutal), phenobarbital (Luminal), secobarbital (Seconal), clonazepam (Klonopin), lorazepam (Ativan), zolpidem (Ambien), and others.
