Public Description:

Hypericum is a genus of herbaceous annual or perennials to shrubs and small trees known as “St.John’s-wort”, has a nearly worldwide distribution, missing only from tropical lowlands, deserts and polar regions. There are approximately 458 species in the world and 96 species (104 taxa) in Türkiye. The flowers vary from pale to dark yellow, rarely red colour. Some species with large flashy flowers are used as ornamental plants. St. John's Wort can be seen as a weed in agricultural land and gardens. These plants have an anti-sensitizing effect on the light and sometimes cause abortions when consumed by animals too much. Common St. John's-wort (Hypericum perfoliatum L.) has long been used as a herbal remedy. The oils of this plant are antiseptic, antiviral and and astringent, especially for cuts or skin wounds.
