Illustration of Soggy Pulse (rumai) 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: The pulse image of Soggy Pulse is as follows. It is imperceptible when pressed, and can be felt only with a gentle touch; it lacks force and feels like cotton floating in water. Soggy Pulse relates to deficiency (vacuity, xu) conditions. When Soggy Pulse is found at the cun (Inch) pulse sector of the wrist, it indicates Yang deficiency (yang xu), spontaneous sweating and cold in shangjiao (the Upper Burner); at the guan (Pass) sector, it indicates enfeebled Qi in the spleen, deficiency-cold (xuleng), and swelling in the lower part of the body(?); at the chi (Foot) sector, it indicates blood deficiency, fever and malign cold (e han).
