Totally unrelated but the active compound in Passion flower is also a flavonoid. Don’t remember the name atm, I can add it later. It’s active at serotonergic receptors and there’s an extract available on eBay atm that is quite nice.
For anyone wondering, that would be scopoletin also an acetylcholinesterase inhibitor. Scopoletin is found in higher amounts in Viburnum opulus (Guelder rose) a western botanical and Brunfelsia grandiflora sometimes used in ayahuasca.
The results indicate that its antidepressant-like effect is dependent on the serotonergic (5-HT2A receptors), noradrenergic (α1- and α2-adrenoceptors) and dopaminergic (D1 and D2 receptors) systems.
