St John¡¯s wort (traditionally pronounced /sejntÈd’Rnz Èwrt/, now sometimes the spelling pronunciation /ÈwTrt/)[1] is the plant species Hypericum perforatum, also known as Tipton¡¯s Weed or Klamath weed, but, with qualifiers, is used to refer to any species of the genus Hypericum. Therefore, H. perforatum is sometimes called Common St John¡¯s wort to differentiate it. The species of Hypericum have been placed by some in the family Hypericaceae, but more recently have been included in the Clusiaceae.[2] Approximately 370 species of the genus Hypericum exist worldwide with a native geographical distribution including temperate and subtropical regions of North America, Europe, Asia Minor, Russia, India, and China.

St. John¡¯s wort is widely known as a herbal treatment for depression.
