In traditional bouts, amulets are often used as forms of supernatural protection. Amulets are seen in modern urban bouts, too, but officials generally discourage the use of magical protection on the grounds of fairness. It is still common that amulets are placed in the feather filled pillows which fighters place in their wrapped fists, and fighters often scar their striking arm, rubbing salves and resins into the healing wounds which are meant to provide strength or defence. Some modern traveling boxing companies engage in ritual smoking of Hemp or Marijuana before bouts.
