In this study, the effects of a commercial St. John's wort extract (STW3-VI), hyperforin, miquelianin, and the selective serotonin reuptake inhibitor citalopram on the expression of genes relevant to HPA axis function were investigated in human neuronal cells. Hyperforin is believed to be responsible for most of the medicinal benefits of St. John’s wort. The randomized, placebo-controlled, multi-center study recruited 147 patients and divided them into 3 groups after a week on placebo.

Meta-analyses of quality clinical trials support a place for St. John's wort in the treatment of depression as mono- or adjunctive therapy. The specific mechanism by which hyperforin achieves these blockages involves the activation of an ion channel known as transient receptor potential ion channel or TRPC6. Besides the monoamine neurotransmitters, hyperforin also blocks the reuptake of glycine and choline. W e demonstrate that the phloroglucinol derivative hyperforin is not only the major lipophilic chemical constituent of the medicinal plant Hypericum perforatum (St. John's wort) but also a potent uptake inhibitor of serotonin (5-HT), dopamine (DA), noradrenaline (NA), GABA and L-Glutamate with IC50 values of about 0. As an anti-inflammatory agent, hyperforin inhibits the cyclooxygenase, COX-1, and the lipoxygenase, 5-LO. However, not all the plants in this family produce hyperforin. Over the next 42 days, one group continued on placebo; another group received an extract with 0.5% hyperforin while the third group was given another extract containing 5% hyperforin. By activating this ion channel, hyperforin allows the inflow of calcium and sodium ions into nerve cells and thus prevents the reuptake of monoamine neurotransmitters.

These neurotransmitters are released into the synaptic gap, allowed to work for a while and then removed from these gaps back into the vesicles where they are stored.
