What is St. John’s Wort?

 

Hypericum perforatum, also known as St John's wort, is a flowering plant species of the genus Hypericum 

 

and a medicinal herb that is sold over-the-counter as a treatment for depression. Other names for it include 

 

Tipton's weed, rosin rose, goatweed, chase-devil, or Klamath weed. With qualifiers, St John's wort is used

 

to refer to any species of the genus Hypericum. Therefore, H. perforatum is sometimes called common St

 

John's wort orperforate St John's wort to differentiate it. Hypericum is classified in the family Hypericaceae,

 

having previously been classified as Guttiferae or Clusiaceae. Approximately 370 species of the genus 

 

Hypericum exist worldwide with a native geographical distribution including temperate and subtropical

 

regions of Europe, Turkey, Ukraine, Russia, Middle East, India, and China.

 

 

 

What is St. John’s Wort Extract Hypericin?

 

Hypericin is a naphthodianthrone, a red-colored anthraquinone-derivative, which, together with hyperforin,

 

is one of the principal active constituents of Hypericum (Saint John's wort). Hypericin is believed to act as

 

an antibiotic, antiviral and non-specific kinase inhibitor. Hypericin may inhibit the action of the enzyme 

 

dopamine β-hydroxylase, leading to increased dopamine levels, although thus possibly decreasing 

 

norepinephrine andepinephrine.
