Passionflower

Passiflora incarnata (passionflower) may help treat anxiety and insomnia.

P. incarnata has many common names, including purple passionflower and maypop. Early studies suggest it might help relieve insomnia and anxiety. It appears to boost the level of gamma-aminobutyric acid (GABA) in your brain. This compound lowers brain activity, which may help you relax and sleep better.
