Also known as Hypericum perforatum.
St. John's Wort is a bushy perennial plant with numerous yellow flowers. It is native to many parts of the world including Europe and the United States. The plant has been used as an herbal remedy since the Middle Ages. Many believed it to have magical powers to protect one from evil. Early Christian mystics named the plant after John the Baptist and is traditionally collected on St. John's Day, June 25.
It has a 2,400-year history of safe and effective usage in many folk and herbal remedies. St. John's Wort itself is a plant that grows in the wild and is harvested for its active ingredient, Hypericum (Hypericin). St. John's Wort should not be taken with any other antidepressants.
As there are several different types of antidepressants, ones such as Prozac in particular are commonly referred to as SSRIs, or Selective Serotonin Reuptake Inhibitors.
Its action is based on the ability of the active ingredient, Hypericin to inhibit the breakdown of neurotransmitters in the brain. The herb also inhibits monoamine oxidase (MAO) and works as a serotonin reuptake inhibitor (SRI).
The active constituents in the herb (there are over 50) include, as already mentioned, Hypericin and pseudohypericin, but also flavonoids, tannins and procyanidins.
