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).
Right-hand illustration:
Xin ju (heart abscess), you yong (hidden abscess), he yong (conspicuous abscess) and xiaofu yong (underbelly abscess) belong, in Chinese medicine, to the category of ulcer and abscess diseases (yongju bing). The illustration shows the disease location for each of these conditions. Xin ju occurs at the juque (Great Gateway) point, at the front of the thorax. You yong occurs at the shangwan (Upper Cavity) point, 7 cun (Chinese/proportionate inches) above the navel. He yong occurs 3 cun below the navel. Xiaofu yong generally refers to abscesses found around the qihai (Sea of Qi) and guanyuan (Pass to the Origin) points, below the navel; but here, it seems to indicate umbilical hernia accompanied by abdominal pain.
Left-hand illustration:
Yao ju (Calamitous abscess), rui du (sharp poison), shenshu fa (Kidney Conveyor lesion), quankou ju (cheekbone-opening abscess), xuanyong (suspended ulcer) and weizheng du (Middle of the Crook poisoning) also belong to the category of abscess and ulcer dieases. The illustration shows the disease location for each of these conditions. Abscesses occurring 1.3 cun (Chinese/proportionate inches) behind the ear are called yaoju if found on the left side, and ruidu if found on the right. Shenshu fa occurs at the shenzhu (Kidney Conveyor) point on the lower back. Quankou ju occurs at the tip of the coccyx. Xuanyong occurs behind the scrotum and in front of the anus. Weizheng du (Middle of the Crook poisoning) occurs at the weizheng (Middle of the Crook) point in the popliteal fossa.
