Illustration of Marble pulse (danshi mai) from Renyuan maiying guizhi tushuo (Pictorial Handbook of Pulse Images Based on the Person). This is a specialist text on pulse diagnosis attributed to the third-century master Shuhe, edited and revised by Shen Jifen in the Ming period (1368-1644). It discusses various pulse images and the medical conditions to which they relate, and contains 48 pulse image diagrams. This undated edition was engraved and published in Japan.
The text states: Marble (i.e. taw) pulse is one of the Sixteen Weird Pulses (guai mai). It is also known as Ghost Corpse (gui shi) pulse. Its pulse image is staccato and sudden and rapid in onset, like stone pellets striking against rock. The presence of this pulse indicates that the Qi of the Kidney channel of Leg shaoyin is exhausted. A patient having this pulse will die within one day.
