Hypericum perforatum (LINN.), Herb tops, flowers, or whole herb used.
Appearance:
Dark brown to brownish-black powder

Hypericin 0.3% UV
Pharmacological Actions:
Hypericum extract contains numerous active compounds that together create the antidepressant and antianxiety effects. Hypericum is the first known substance to enhance three key neurotransmitters- serotonin, norepinephrine, and dopamine. Preliminary research suggests that St. John's Wort also lowers levels of the stress hormone cortisol and enhances the activity of gamma-aminobutyric acid (GABA), a naturally occurring tranquilizer in the brain. It is a very mild, clinically insignificant monoamine oxidase (MAO) inhibitor.
