How does St John’s wort work?

The plant is known to have active chemical component hypericin while others include hyperforin and flavonoids.

How St. John’s work for the treatment of anxiety and depression is not precisely known, but it most likely works as a selective serotonin reuptake inhibitor (SSRI) like fluoxetine, or Prozac which helps to increase the secretion of the chemical in the brain such as dopamine, serotonin, and norepinephrine.

These are neurotransmitters that help to elevate mood. Previously it was believed that hypericin is only responsible for it, but now studies suggest that other chemicals may also play a role in decreasing depression and improve mood.

Not all the research studies, however, agree with the effectiveness of St. John’s wort for anxiety and depression.

But these studies have also been weighed against the studies that show its efficacy similar to that of drugs like Prozac, Celexa, paroxetine (Paxil), and Zoloft.
