Wrap treatments using the liquid for external use "Retterspitz Äußerlich" (with the wrap “Retterspitz Wadenwickel” or “Retterspitz Leibwickel”) naturally reduce fever and provide relief. Apply the body wrap “Retterspitz Leibwickel“ with Retterspitz Äußerlich once or twice a day until your temperature returns to normal. Fever often begins with chills and shivering. In this stage, the body must be warmed up. Adding the bath essence concentrate “Retterspitz Badekonzentrat” to a warm bath is the perfect way to do this.
