What is passionflower?
Passionflower has a long history of medicinal use in Central and North American herbal medicine. Seeds that were thousands of years old were found in the Americas where the Algonquian Native Americans thrived. Various indigenous groups used the flower and root extensively to treat wounds and boils, as a gentle sedative, and as a tonic. Legend has it that the plant was discovered in Peru by a Spanish doctor during the 16th century - when Spanish missionaries saw the flower, they saw it as a physical representative of the crucifixion of Christ, giving rise to the name passionflower.

The health benefits of passionflower according to research
1. Heart and Circulatory Health
Passionflower may be useful in lowering blood pressure by dilating the arteries since it reduces stress and anxiety. According to the Journal of Nutritional Biochemistry, passionflower extract was found to reduce blood pressure levels. Scientists believe that a compound known as edulilic acid found in passionflower may be responsible for its blood-lowering effects.
2. Sleep Support
Passionflower is often recommended by doctors as a mild sedative for those suffering from insomnia or nervous exhaustion. Combining valerian root with other mildly sedating herbs such as passionflower and chamomile are also commonly recommended by doctors. These herbs can also be used alone as mild sedatives for those suffering from insomnia or nervous exhaustion. Preliminary clinical research suggests drinking one cup of passionflower tea an hour before going to bed improves measures of sleep quality.
3. Stress & Mood Support
According to modern research studies, passionflower reduces anxiety without inducing sedation. In one study, a combination of passionflower and valerian was shown to reduce symptoms in people suffering from anxiety. In another study, passionflower extract was shown to be as effective as a prescription medication used for anxiety.
Scientists believe that passionflower works by increasing levels of a chemical called gamma aminobutyric acid (GABA) in the brain. GABA has a calming effect by lowering the activity of some brain cells.
