Finally...FURA-FREETM Non-CarcinogenicNo rashes! FURA-FREETM heals cracked heels, wounds, burns and abrasions faster than nitrofurazone products. FURA-FREETM also forms a thinner, more flexible scab, less likely to break open and bleed again. Best of all, FURA-FREETM is nitrofurazone-FREE! We do NOT use nitrofurazone since studies suggest that nitrofurazone has carcinogenic or cancer-causing properties.
