Islam's owner the false prophet Muhammad had lots of odd fetishes. Camel urine was among his obsessions which he preached was the miracle cure for a whole host of ailments.
Sahih Bukhari 7:71:590
The environment of Medina did not fit some individuals, so the Prophet got them to follow his shepherd, i.e. his camels, and also drink their milk as well as pee (as a medicine). So they adhered to the shepherd that is the camels as well as consumed their milk and also pee till their bodies came to be healthy and balanced.
