Finally...FURA-FREE Non-CarcinogenicNo rashes! FURA-FREE heals cracked heels, wounds, burns and abrasions faster than nitrofurazone products. FURA-FREE also forms a thinner, more flexible scab, less likely to break open and bleed again. Best of all, FURA-FREE is nitrofurazone-FREE! We do NOT use nitrofurazone since studies suggest that nitrofurazone has carcinogenic or cancer-causing properties. Read the human carcinogenic warning on the jar of nitrofurazone products: They warn you not to touch the product with your bare hands! The RIGHT STUFF is available from Finish Line®. FURA-FREE contains the same type of polyglycol base, which has a very low thermal conductivity, making it an excellent sweat. Since the base is the same, the physical properties during application such as viscosity and softening range are similar also.
