Abstract
Abstract In a method and means (cooling pack) for cooling injured parts or areas of a human or animal body, xylite (C 5 H 12 O 5 ) is used as the cold means. The xylite is dissolved in crystalline form in an aqueous or non-aqueous fluid and brought into direct or indirect contact with the part or area of the body to be cooled. The xylite may preferably be accommodated in a flexible container to which the solvent fluid can be supplied directly or from a container joined thereto.
