St John's wort (hypericumperforatum) is known under different names in modern Greece. The name hypericum derives from hyper (above) and eikon (an image or apparition) and relates to the folk belief that the herb could exorcise evil spirits. It is a perennial plant with reddish stems and a bitter taste. It grows in fields, meadows and mountain slopes. It blooms in summer when it is harvested and then dried. St John’s wort should only be taken as an extract or a pill. It helps wound healing, insomnia, headaches, and is effective for mild or moderate depression. Other uses of the herb include digestive and urinary conditions. People being treated with any medications, should not use St. John's wort without first consulting their doctor or pharmacist.
