Compounds known as flavonoids have antioxidant and anti-inflammatory effects.
Physiological Mechanism of Action of St. John’s Wort
Although the precise physiological mechanism of St. John’s wort’s action is not completely known, it is thought to be a result of hypericin and hyperforin’s effects on brain neurotransmitters like serotonin, dopamine, and norepinephrine.
Serotonin, dopamine, and norepinephrine are released more readily by the body with the intervention of hyperforin while their absorption is inhibited. This causes these neurotransmitters’ concentrations in the brain to rise, which may have antidepressant and anxiolytic benefits.
Hypericin has been shown to have antiviral effects by inhibiting the enzyme monoamine oxidase (MAO). MAO is in charge of breaking down functional serotonin, dopamine, and norepinephrine. Hence, MAO may also have depressive effects.
