Fraisenketten; Christianity already found the use of amulets, pendants, stones, etc. in popular belief and took over this form of blessed and special materials and objects. The Fraisenkette is a protective amulet. On a ribbon several amulets, blessing signs or protective objects were lined up. "Fraisen" is a historical term for epilepsy or seizures. The latter were often caused by the consumption of bread from cereals infested with ergot.
