Force-fire
The force-fire (, which also translates to Need-fire), or a fire produced by friction, was used in folk magic practice in the Scottish Highlands until the 19th century. Believers considered it an antidote against bewitching, as well as the plague, murrain and all infectious diseases among cattle. It is also known as In Scotland and elsewhere as Need-fire or Neatsfire from an old word for cattle retained in the name " neatsfoot oil".
