《周礼·天官冢宰·亨人&兽医》
凡治疗畜病，先灌药使它行走，节制它行走的快慢，以发动它的脉气，再观察所发的脉气而加以治疗。
凡疗兽病，灌而行之，以节之，以动其气，观其所发而养之。
In treating diseases in animals, they first gave the animal a purgative to get it walking, controlled the speed of its gait to make its pulse beat faster, and then observed the resulting pulse and administered a cure based on the pulse.
