Description: Passionflower is a perennial climber with deeply lobed, finely toothed leaves, with fragrant lavender to white flowers appearing in summer. Edible fruits follow the flowers of passionflower.
Uses: Passionflower is used internally to treat nervous restlessness, sleep disorders, anxiety, neuralgia, irritability and overcoming the difficulty in falling asleep. The ripe passion fruits are eaten raw and can be made into jellies, jams, wines and fruit based drinks, while the flowers are made into syrup. Its narcotic properties cause it to be used in diarrhea and dysentery, neuralgia, sleeplessness and dysmenorrhea.
Passionflower is used for sleep problems (insomnia), gastrointestinal (GI) upset related to anxiety or nervousness, generalized anxiety disorder (GAD), and relieving symptoms related to narcotic drug withdrawal.
Passionflower is also used for seizures, hysteria, asthma, symptoms of menopause, attention deficit-hyperactivity disorder (ADHD), nervousness and excitability, palpitations, irregular heartbeat, high blood pressure, fibromyalgia, and pain relief.
Some people apply passionflower to the skin for hemorrhoids, burns, and pain and swelling (inflammation).
In foods and beverages, passionflower extract is used as a flavoring.
In 1569, Spanish explorers discovered passionflower in Peru. They believed the flowers symbolized Christ’s passion and indicated his approval for their exploration. Passionflower is found in combination herbal products used as a sedative for promoting calmness and relaxation. Other herbs contained in these products include German chamomile, hops, kava, skullcap, and valerian.
Passionflower was formerly approved as an over-the-counter sedative and sleep aid in the U.S., but it was taken off the market in 1978 because safety and effectiveness had not been proven. However, passionflower may still be available alone or in combination with other herbal products.
