Passionflower Extract
Also known as: Passiflora incarnata, maypop, passion flower, passiflora extract
An extract of the aerial parts of Passiflora incarnata, a climbing vine used in calming and sleep formulas. A double-blind trial found that a single 500 mg oral dose taken before ambulatory surgery reduced pre-procedure anxiety without slowing recovery, and an earlier four-week pilot compared a liquid extract favorably with a benzodiazepine on anxiety scores. It is mild, pairs well with valerian and lemon balm, and is usually taken in the evening.
Research summary
Flavonoids such as vitexin and chrysin, along with harman alkaloids, are proposed to modulate GABA-A receptor activity and reduce central excitability.
