Synopsis

Rating (out of 5): 3

Passiflora, commonly known as passionflower, has a long history of use in traditional herbal medicine systems, particularly in the Americas and Europe, for its calming and sedative properties. Traditionally, Passiflora has been used to alleviate symptoms of anxiety, insomnia, and mild stress, all of which are closely related to the activity of the parasympathetic nervous system—which governs the body’s rest-and-digest functions. Ethnobotanical sources and historical records document its use as a mild tranquilizer and sleep aid. The sedative effects are thought to arise from its influence on neurotransmitter systems, potentially increasing gamma-aminobutyric acid (GABA) activity in the brain, leading to relaxation and reduced nervous system excitation.

While some modern studies suggest anxiolytic and sedative effects of Passiflora extracts, clinical evidence remains limited, and most studies are small or have methodological weaknesses. However, the traditional use is well-established for supporting the body’s natural relaxation response, which is mediated by the parasympathetic nervous system. Thus, the justification for using Passiflora to support the parasympathetic nervous system is primarily based on its traditional usage, though emerging scientific interest may provide further support in the future.
