POO was collected in canoes placed carefully under bridges that had loos at regular intervals. It was taken away and used as perfectly good manure/fertiliser (apparently, it conserves valuable elements like nitrogen and phosphorous - the ancient Chinese did the same).
PEE had many uses. Alfredo López Austin explains: ‘Without a doubt, urine was the product of the human body most used in ancient therapeutics [remedial medicine]. It was utilised to treat the sternum [breastbone], dandruff, boils on the head, ringworm of the scalp, abscesses, wounds, ear infections, chapped faces, neck infections, and even tartar on the teeth as well as internal contusions [bruises], this last requiring the medicine to be drunk.’ (Yuk!)
