The Ishinpō is notable for preserving some of the Taoist sexual manuals from the Han to the Tang dynasty. The twenty-eighth section of the Ishinpō contains a complete transcription of a Daoist text known as The Classic of Sunu which is a dialogue between the Dark Maiden and the Yellow Emperor, with the former providing advice on sexual practices to the latter.
While the text is written in kanbun, Japanese terms are written to the side in Man'yōgana for plants, animals, and minerals.
