Brown Yellow Powder HPLC UV 3% Hypericin St John's Wort Extract powder


General Description


The St. John's wort mechanism is believed to inhibit the uptake of serotonin (5-HT) dopamine, and

noradrenaline,much like the conventional selective serotonin reuptake inhibitor (SSRI) antidepressants.

It also has affinity for GABA and glutamate receptors. The major active antidepressive constituents in St.John's

wort are thought to be hyperforin and hypericin, although other biologically active constituents present,

for example, flavonoids and tannins, may also be involved.
