'Diagram of zang and fu viscera, Yin and Yang, cold and heat' from Yijing xiaoxue (A Little Primer of the Medical Canon), publ. 1438 (3rd year of the Zhengtong reign period of the Ming dynasty), Juan (Volume) 2: Pulses, Rhymes of the Pulses, 2.
Yijing xiaoxue, in six juan, condenses the medical canon and the work of some of the most celebrated pre-Ming physicians into simple, concise verse. It covers materia medica, the pulses, the channel (meridian) system, disease processes, treatment and the movement of Qi (yun qi). The book is entirely written in rhyme, for ease of memorization.
This page is a ready-reference guide to the pulse images corresponding to three pairs of concepts -- zang and fu; Yin and Yang; cold and hot. The text states: If Slow Pulse (chimai) is found at the cun (Inch) pulse sector of the wrist, it indicates a cold syndrome in the viscera. Rapid Pulse (shuomai) at the cun sector indicates a heat syndrome in the viscera. Cold syndromes are classed as Yin and heat syndromes as Yang.
