Abstract
Abstract The invention concerns a therapeutic dressing comprising an elongated flexible permeable support and a mixture of mineral components comprising 16 to 24% by mass of South African bentonite, 16 to 29% by mass of Kaolinite and 47 to 68% total by mass of South African illite and/or attapulgite, which mixture has been rendered into paste-form by the addition of at least an equal part by weight of a liquid mixture comprising 6 to 10 parts by mass of water and 6 to 2 parts by mass of glycerine.
