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.

 Function:

1)St. John’s Wort contains many different substances that work together. A major compound is hypericin.

2)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).

3)Hypericin is believed to act as an antibiotic, antiviral and nonspecific kinase inhibitor. Hypericin may inhibit the action of the enzyme dopamine β-hydroxylase, leading to increased dopamine levels, although thus possibly decreasing norepinephrine and epinephrine.
