Chinese woodcut: Abscesses -- zouma gan (galloping sore)

Woodcut illustrating the 17th century text Xu Ping waike zhengzong (Orthodox Manual of External Medicine with Commentary by Xu Dachun), from an edition published in 1860 (10th year of the Xianfeng reign period of the Qing dynasty). It shows the disease location for zouma ju (galloping sore), also known as zouma ya ju (galloping dental sore). The symptoms are sepsis of the gum, which becomes black, putrid and fetid. As the disease advances, the gums rot away, and the infection eats through the cheek and destroys the lips. The disease owes its name to the rapidity with which it progresses.
