[Discussion on the meaning of "<i>yinluo</i>" in <i>Suwen: Shuire Xue Lun</i>].

By analyzing the understandings of water points (acupoints connected with the kidney) and its association with water (kidney), <i>zangfu</i> organs and meridian-collateral recorded in <i>Suwen: Shuire Xue Lun</i> (<i>Discussion on Water and Heat Diseases in Plain Question</i>), it is found that the recognition on the water points is different from that on water diseases in <i>Huangdi Neijing</i> (<i>the</i> <i>Yellow Emperor </i>'<i>s Inner Classic</i>)<i>.</i> 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 "<i>luo</i>" in <i>Huangdi Neijing</i>, it is discovered that "<i>yinluo</i>" discussed in water points is actually the misunderstanding of "<i>zang zhi yinluo</i>" that means "the connection by the kidney". It is shown that the discussion of water points refer to the elaboration of <i>zangfu</i> organs and 57 acupoints connected with water (the kidney), rather than the theory of collaterals. The characteristics of these 57 acupoints involved and the related needling techniques provide a new approach to the treatment of <i>zangfu</i> diseases.
