St. John's wort is a very old perennial medicinal herb that has been used as a medicinal plant since ancient times and is highly valued. St. John's wort originally comes from Europe, North Africa and Central Asia, but it can now be found almost worldwide, especially on roadsides, dams and in open forests on dry and calcareous soils. The symbolic medicinal plant has a long history of use and was used for somatic and psychological treatments several hundred years ago. The striking red oil has a high proportion of the active ingredient hypericin, which is used for rheumatism, gout, tension, depression, lumbago and injuries. The herb has a mood-enhancing and calming effect and is often prepared as a tea. The traditional burning of the herb on St. John's Day is a symbol of the sun. A popular bee pasture for insects.
