A poultice is a material that “draws” fluid into it from an adjacent material. I have used “sugardine” frequently in my practice over the years, primarily on the sole of the hoof, where it has a drying and drawing effect. This paste can be used on certain skin wounds too.
Pour 1/4 cup of sugar into a cup. Add about 3 tablespoons of povidone iodine solution to it. Using a spoon or tongue depressor, stir it until it becomes a thick granular paste (the consistency of cake frosting). Use a tongue depressor, gloved hand or 4x4 gauze pad, to apply it liberally to a defect in the hoof. Apply gauze pad over it and a hoof bandage over the top of that.
