Well.. this is what I got when I searched the question. Hope it helps.
Purist nutjobs exist in all religions.
There's a bunch of purists who use our holy Prophet (SAW) Hadiths on the medicinal benefits of camel urine. Here's the except from the Hadees on camel urine.
Some people of ‘Ukl or ‘Uraina tribe came to Medina and its climate did not suit them ... So the Prophet ordered them to go to the herd of (Milch) camels and to drink their milk and urine (as a medicine). So they went as directed and after they became healthy.
