The mode of action of passionflower extracts is insufficiently researched clinically. It is possible that ingredients of the plant bind centrally and peripherally to specific receptors (GABA-A receptors), through which a sedative effect is mediated. In animal experiments, the calming and anxiety-relieving effects have been demonstrated.
