Warnings:
A study mentions a possible uterotonic effect, preventing Passion Flowers use during pregnancy. Moreover, its traditional use for dysmenorrhea adds another doubt as to its safety during pregnancy.

Additional Information:
Passion Flowers main chemical components are alkaloids (harmane, harmaline, harmanine, etc.), flavonoids (vitexine, apigenine, luteoline, quercetine, etc.), maltol and ethylmaltol, sterols, etc.
Cyanogen molecules (producing cyanide in certain conditions) were presumably found in Passion Flower. These molecules have only been identified in a few varieties like Passiflora biflora, P. talamancensis, etc., but never in Passiflora incarnata.
The flavonoid apigenine links with GABA receptors, which could explain part of Passion Flowers tranquilizing effect. The alkaloids harmanes may inhibit monoamine oxidase, implying possible antidepressant and stimulant effects. Maltol and ethylmaltol may have sedative and anticonvulsant effects. However, there are too few of these molecules to validate these effects.
Like that of many other herbs, Passion Flowers effectiveness on anxiety and nervousness relies on the synergy of its components.
