Description:

St John's wort, Hypericum perforatum, has been used for the past 2,000 years as a medicinal herb. The genus name Hypericum is from the Latin word hyper, meaning "above," and icon, meaning "spirit." The herb was once hung above doorways to ward off evil spirits. The species name perforatum refers to the many puncture-like black marks on the underside of the plant's leaves. The plant, especially its tiny yellow flowers, is high in hypericin and other flavonoid compounds. Native to Europe, St. John's wort is now found growing in dry areas of many temperate climates throughout the world. 
St John's wort 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. Therefore, H. perforatum is sometimes called Common St John's wort to differentiate it. 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 today most widely known as an herbal treatment for depression.

According to the Cochrane Review, a key resource in evidence-based medicine, the available evidence suggests that the hypericum extracts tested in the included trials are superior to placebo in patients with major depression; are similarly effective as standard antidepressants; and have fewer side effects than standard antidepressants.
