Possiflora incarnata L. - Passion flower

Abstract: The herb of passion flower (Passiflora incarnata L.) was introduced into European phytotherapy via homeopathy. There are a variety of indications for the traditional use of the drug in Europe. While Passiflora is generally acknowledged as a sedative, the cardiotonic effect corresponding to that of hawthorn is known in general in France and in Switzerland only. Former and recent pharmacological in vitro studies and animal experiments confirm the traditional use of Passiflora. Modern human-pharmacological trials however are missing. The herb of passion flower is mainly used in combination with other drugs having the same or at least similar indications. The main constituents are C-glycosylflavones. Harmanalkaloids do not play a role because of their low concentration. Maltol is rather an artifact than a relevant constituent. The fruits of Passiflora, which gain increasing significance in Europe thanks to the international trade, are not derived from the same species as the officinal drug, but from two subspecies of Passiflora edulis SIMS.
