St. John's Wort



Standardized herbal extract

  • St. Johns Wort (Hypericum perforatum) and its active constituent, hypericin, help to increase one of the brains neurotransmitters, serotonin, by blocking the action of mono-amine oxidase (MAO), the enzyme responsible for breaking down serotonin, and by impairing the uptake of serotonin into nerve cells.
  • Clinical studies with St. Johns Wort extract have demonstrated that this herb helps support normal psychological mood.
