By analyzing the understandings of water points (acupoints connected with the kidney) and its association with water (kidney)

(

Discussion on Water and Heat Diseases in Plain Question

)

it is found that the recognition on the water points is different from that on water diseases in

Huangdi Neijing

(

the Yellow Emperor's Inner Classic

)

.

The recognition on the water points focuses on the core theory

"rooted at the kidney"

to explain the water diseases. Besides

in association with the study on the connotation of "

luo

" in

Huangdi Neijing

it is discovered that "

yinluo

" discussed in water points is actually the misunderstanding of "

zang zhi yinluo

" that means "the connection by the kidney". It is shown that the discussion of water points refer to the elaboration of

zangfu

organs and 57 acupoints connected with water (the kidney)

rather than the theory of collaterals. The characteristic

s of these 57 acupoints involved and the related needling techniques provide a new approach to the treatment of

zangfu

diseases.
