Acu-moxa point chart, showing the
zhiyin (Reaching Yin) point, here also described as the 'difficult birth' point, from
Chuanwu lingji lu (Record of Sovereign Teachings), by Zhang Youheng, a treatise on acu-moxa in two volumes. This work survives only in a manuscript draft, completed in 1869 (8th year of the Tongzhi reign period of the Qing dynasty). It is illustrated with 84 charts, finely executed in colour.
The text states: The zhiyin point is located on the outer side of the little toe beside the corner of the toenail. This point is moxibusted with three moxa cones, the size of a grain of wheat. It can cure severe complications of childbirth.
