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 'Bone Covering' (mengwei) pox, in traditional ink and brush style, comes from The Gold And Chalcedony Mirror of Pox Diseases.
The text states: Pox (dou) that erupt in clusters on the high bone behind the ear are called Bone Covering (mengwei). This is a symptom of poison entrenched in the Kidney channel. It should be treated by purging fire and removing poisons by means of Muscle Freeing and Poison Expelling powder (songji tongdu san) in conjunction with Poison Dissolving elixir (huadu dan) and pig's tail grease. Cochineal ointment can be applied externally.
