5. Kidney Disease Pattern Differentiation

5. Kidney Disease Pattern Differentiation

Dizziness, tinnitus, lower back pain, and leg fatigue, along with a weak chi pulse, constitute the kidney-deficiency symptom cluster. If accompanied by bone-steaming heat, five-heart heat, and night sweats, it is kidney-yin deficiency; if accompanied by cold limbs and spontaneous sweating, it is kidney-yang deficiency. Treatment for kidney-yin deficiency is to nourish yin and replenish the kidneys, using Liu Wei Di Huang Tang (from "Xiaoyuer Yaozheng Zhijue"); kidney-yang deficiency can be further divided into the following four types, each treated separately:

(1) Kidney Not Storing Essence

Basic symptoms of kidney-yang deficiency include nocturnal emission and impotence—treatment involves strengthening the kidneys and solidifying essence, using Bu Shen Wan (from "Yinhai Jingwei").

(2) Kidney Not Receiving Qi

Basic symptoms of kidney-yang deficiency include shortness of breath and喘息—treatment involves warming the kidneys and receiving qi, using Du Qi Wan (from "Yizong Ji Ren Bian").

(3) Decline of Life Gate Fire

Basic symptoms of kidney-yang deficiency include diarrhea at dawn—treatment involves warming the kidneys and stopping diarrhea, using Si Shen Wan (from "Neike Zhaiyao").

(4) Yang Deficiency Leading to Water Overflow

Basic symptoms of kidney-yang deficiency include generalized or regional edema—treatment involves warming yang and transforming water, using Zhen Wu Tang (by Zhang Zhongjing).

Appendix: 1. Lower Yuan Deficiency-Cold: enuresis, frequent urination, nocturia, cold lower abdomen—treatment involves warming and tonifying the lower yuan, using Suo Quan Jiu (from "Furen Liangfang"). 2. Bladder Damp-Heat: frequent urination, urgency, pain, and tight lower abdomen—treatment involves clearing heat and draining dampness, using Ba Zheng San (from "Jufang").

The above zang-fu pattern differentiation symptom clusters can appear individually, but in most cases, several zang-fu syndromes often occur together. For example, heart-spleen dual deficiency syndrome, spleen-kidney yang deficiency syndrome, and liver-kidney yin deficiency syndrome. Heart-spleen dual deficiency syndrome is formed by the combination of heart-blood deficiency and spleen qi deficiency, meaning it includes both the pale complexion, poor appetite, fatigue, and shortness of breath associated with spleen qi deficiency, as well as the palpitations, forgetfulness, insomnia, and frequent dreaming associated with heart-blood deficiency. The representative formula for treating this syndrome is Gui Pi Tang, which contains ingredients that strengthen the spleen and tonify qi, such as dang shen, bai zhu, fu ling, and huang qi, as well as ingredients that nourish the heart-blood, such as yuan zhi, yuan rou, and fried jujube seeds. As long as one masters the individual zang-fu syndromes, it is easy to analyze, understand, and recognize their combined clinical manifestations.

III. Fever Disease Pattern Differentiation

Fever disease is a general term for both Shanghan and Wenbing. Shanghan is caused by cold pathogens, while Wenbing is caused by heat pathogens. Although the causes are different, both share the characteristic of fever and fall under the category of exogenous diseases, hence they are collectively referred to as fever disease and also as exogenous diseases. Traditionally, TCM uses the six-channel pattern differentiation in "Shanghan Lun" to differentiate Shanghan, and relies on "Wen
