Product Description

 

 

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.
