Sometimes people needed a bit more help to purge, and the physician would administer aclysteror enema. For example, John of Arderne, a famous English surgeon, mixed water with honey, oil, wheat bran, soap and herbs such as mallow and camomile. He would squirt it into the patient’s anus used a greased pipe fixed to a pig’s bladder, while the patient rubbed his stomach. This would clear out any stubborn blockages.
