St John's Wort extract has long been used as an antidepressant in Europe (especially Germany), but research on its mechanism and effective ingredients is still under exploration. It is generally believed that St John's Wort, like ordinary antidepressants, inhibits the reabsorption of norepinephrine and serotonin.
It is theorized that St John's Wort acts simultaneously in many ways: inhibiting the reabsorption of norepinephrine, serotonin and dopamine; low-level MAOI (monoamine oxidase inhibitor); acting on the hypothalamus, inhibiting the secretion of cortisol. There are also theories that the crude extract of St John's Wort has a good affinity for some receptors related to the mass transfer of brain nerves, such as GABA (γ-aminobutyric acid).
GABA is one of the main substances that calm the central nervous system. New research shows that GABA is also related to antidepressant. Depression patients have very low GABA levels, and drugs that can enhance GABA activity also have antidepressant effects. It has also been proposed that St John's Wort inhibits the activity of interleukin-6, which is a chemical substance that promotes immunity and can cause depression. And St John's Wort can be used to treat menopausal depression because of the action of β-sitosterol, a mild plant hormone contained in it.
