Abstract: A wound-healing preparation comprises a solution or paste of a non-reducing sugar and iodine in a vehicle consisting essentially of a pharamcologically acceptable glycol, especially glycerol, and, optionally, water. Preferably, the sugar is sucrose, especially that obtained from sugar beet, and the vehicle is substantially anhydrous glycerol. In one preferred embodiment, the preparation is in the form of a veterinary infusible solution and is particularly useful in the treatment of mastitis. In another embodiment, surgical sutures are treated by coating with the preparation to prevent the presence or abscesses around surgical suture lines.
