One of the doctors says that pigeon feces with mumiyo, if injected, drives urine. The remedies mentioned in the section on the treatment of dense blockages, and named as a cure for retention arising from cold, also work. A certain doctor said: “Here is one of the remedies that we tried, and it worked: take a candle from the sand of sugar candy and insert it into the rectum; this drives and releases urine.” They say that if you let a louse into the urinary canal or take a tick, who falls out of bed is probably an insect called al-fasafis bug or al-anjal, and insert it into the urinary canal, this will drive urine. The same thing will happen if you smear the top of the urinary canal with garlic or onion - this drives urine away - or if you put a stalk of saffron into the canal of the penis. When there is no tumor, but there is a blockage, whatever it may be, injecting olive oil in which white, not very harmful scorpions have been dried in the sun, helps; they are administered with a silver syringe and assisted by insufflation.
