The long-lasting, time-release gel formula fights white line disease, seedy toe, thrush, candida yeast, aerobic and anaerobic bacteria, mold, and fungus. Use it in nail holes, cracks, and defects. Apply along horn rim, deep into the sulcus, under shoes, and pads. The tip allows for the exact placement of the gel along the horn rim and frog with no messy waste or run-off. The gel contains a special medical dye that stains diseased hoof tissue and shows where to add more gel as the blue color fades. It can arrest hoof disease that otherwise may result in hoof resection. Help ensure horse hoof health with this solution.
