Illustration of Slippery Pulse (huamai) 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: Slippery Pulse comes and goes smoothly, like an unbroken string of beads. When pressed, it is hidden (fu), but when palpated lightly (ju, lit. raised), it feels abundant. Slippery Pulse relates to nausea and vomiting from retrograde Qi. This is the case when this pulse is present at the cun (Inch) and guan (Pass) pulse sectors of the wrist. At the chi (Foot) pulse sector, it relates to diarrhoea. Slippery Pulse also relates to amenorrhea.
