No Thrush Hoof Powder from Four Oaks Farm Products will change the way you treat thrush. We use is every single day in our barn, especially during those wet fall and spring months. It could not be easier to apply and is much less mess than any other product you might use. I also like the idea that the product is 100% natural and safe. Over and over again is has helped horses with thrushy soles/frogs and sore center heel sulcuses. A light dusting when you pick out feet can help with the prevention of thrush on horses that are prone to it as well.
