 However, legends claim it is notoriously difficult to recognize the herb, and reputedly only certain chthonic animals are able to identify it.The herb is known by a multitude of names among the South Slavs, and the names vary significantly by region.While "razkovniche" and "raskovnik" are the customary names in Bulgarian and Serbian respectively and the root is also preserved in the Leskovac dialect as "raskov", in some parts of Macedonia it is known as "ež trava" ("hedgehog grass").
