Renying

and

Cunkou

pulse diagnostic method is one of the important parts of the pulse diagnosis in

Huangdi Neijing

(

Inner Canon of Yellow Emperor

) and has been controversial since its proposal. This article takes

WANG Shu-he's

diagnostic operation as the evidence

and is in reference of the statement

"

Cun

region (the region ahead of

Guan

region of

Cunkou

) determines the human life

that on the left hand refers to

Renying

while on the right hand is

Qikou

". The pulse conditions on the left and right hands represent

yin

and

yang

. If

Renying

pulse on the left is greater

the diseases are in

yang

meridians

while if

Cunkou

pulse on the right is bustling

the diseases are in

yin

meridians. By comparing the pulse condition and strength

as well as the pulse beating (rapid and urgent) between

Guan

region and region ahead of

Guan

on the same side

the conditions of three

yang

and three

yin

meridians are detected. In treatment

based on the records of

Renying

and

Cunkou

pulse diagnosis in

Huangdi Neijing

the principles are proposed for reinforcing and reducing methods on hand and foot meridians of

yin

and

yang

. Five-

shu

points and

yuan-

source points are taken as the main acupoints in acupuncture treatment. During treatment

the changes in pulse conditions should be emphasized specifically and those at

Renying

and

Cunkou

regions are the criteria for judging

qi

arrival and

qi

regulation.
