No Thrush is the first ever "DRY" approach to thrush treatment. It's Safe, All-Natural formula is "dusted on" with a thin-tipped squeeze bottle, which provides excellent coverage of the infected area. The ingredients have been ground into a fine powder. It coats the area of the infection just as flour coats and stays on your hands while baking. No Thrush finds the damp, deep-in places that wet products cant find. Won't burn your horse's tender tissue with chemicals!
