Heal Balms with Urea

Q: Can heal balms be used that contain urea?

A: Urea is a substance extracted from the urine of animals. It is haraam to use such substances. There are alternate heel balms or similar creams that could be used to treat cracked heels, hence it will not be permissible to use heel balms that contain urea. If the problem is severe and a Muslim doctor advises or experience has proves, that only the heel balm containing urea is beneficial, then to use it will be permissible.
