 Description 
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 can now be found almost worldwide, especially on roadsides, dams and in sparse forests on dry and calcareous soils. The symbolic medicinal plant has a long history of use and was already used several hundred years ago for physical and psychological treatments. The striking red oil has a high proportion of the active ingredient hypericin, which is used for rheumatism, gout, tension, depression, lumbago and also 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.

St. John's wort prefers a permeable, nutrient-poor, calcareous, rather dry and sandy loam soil. It also thrives in all other clay soils. Doesn't tolerate waterlogging.

 Additional tips 
Only plant in neutral or alkaline soils; if the soil is too acidic, St. John's wort absorbs toxic cadmium. In order to quickly obtain a fine, crumbly and permeable soil with good nutrient and water storage capacity, it is recommended to also incorporate biochar and primary rock flour.
