The ingredients of passion flower alter the transmission of stimuli in the brain, where nerve cells communicate with each other and messenger substances are released. It works precisely where feelings of sadness and fear arise. If just thinking about the challenges of the next day drives up blood pressure or a lack of relaxation even prevents you from falling asleep or staying asleep, passion flower extract can alleviate nervous restlessness. It is not known for certain whether the flavonoids, vitexin, coumarin, harmonine or kaempferol contained in the plant are responsible for the effect. Furthermore, not all of its ingredients have been identified to date. What is clear, however, is that the ingredients contained in the leaves of Passiflora incarnata help to relieve tension, irritability and anxiety. Tea or a tincture can also be used to successfully treat back pain and tension, heart pain and gastrointestinal complaints. The calming effect also has a positive impact on the cardiovascular system and thus on blood pressure.
