Mid C20 Chinese medical illustration in trad. style: Smallpox

Youke san zhong (Three Books of Paediatrics) is a mid 20th century composite edition of three classics of paediatrics: Zengbu douzhen yusui jinjing lu (The Gold And Chalcedony Mirror of Pox Diseases, Expanded Edition) by Weng Zhongren (Ming period, 1368-1644), Youke tiejing (Iron Mirror of Paediatrics) by Xia Ding (Qing period, 1644-1911), and Xiao'er tuina guangyi (Overview of Paediatric tuina Massage) by Xiong Yingxiong (Qing period). A small number of illustrations are included in a supplement.

This illustration of 'Mouth Locking' pox, in traditional ink and brush style, comes from The Gold And Chalcedony Mirror of Pox Diseases.

The text states: In 'Mouth Locking' (suokou) there is a pox (dou) lesion at each corner of the mouth which is notably larger and harder than the other lesions, and not coiled(?). If there is a continuous rash around the perimeter of the upper and lower lip, this is also classed as Mouth Locking pox. This condition indicates that the spleen is congested with pathogens. It is treated in the same way as Cauldron Cover (fufu).
