In van der Kroon’s book Golden Fountain he described treating a severe foot injury in India which is where he learned about UT and the healing power of urine.  His foot had become infected and when the locals showed him how to cure it with the topical application of fresh urine onto bandages that were wrapped around it, his injury was cured in just a few days with no other treatment.

Here’s but one description of his healing though it lacks the details but it was through the use of urine compresses:

Kroon first became interested in urine therapy in India after sustaining a serious injury to his foot. When instead of healing, the foot gradually grew worse, someone suggested that he use urine compresses. Having nothing to lose he decided to give it a try - and it worked!
