The Finish Line Fura-Free Sweat & Salve Horse Liquid promotes healthy skin， and it’s safe to use. Because studies have suggested that nitrofurazone may have cancer-causing properties， this product was designed to be nitrofurazone-free for both your and your horse’s health and safety. This liquid both protects and soothes minor cuts， scrapes and burns， and you can also apply it to cracked heels. The formula helps to form a thinner， flexible scab that’s less likely to break open， making wound healing easier. Its natural essential oils include tea tree， myrrh， thyme， lemon balm and calendula， and this blend creates soothing relief for burns， cuts and other irritation. Need to use this product as a sweat on a larger area， like a leg? The liquid form makes that easy， so the only thing sweating will be your horse.
