Article 1 The Master said: There are five types of water disorders: Fengshui (Wind-water), Pishui (Skin-water), Zhengshui (Standard-water), Shishui (Stone-water), and Huanghan (Yellow sweat). In Fengshui, the pulse is naturally floating. The external manifestations include pain in the bones and joints, and aversion to wind. In Pishui, the pulse is also floating. The external manifestations include edema that leaves an indentation when pressed, aversion to wind is absent, abdominal distension like a drum, and absence of thirst. Treatment should involve inducing sweating. In Zhengshui, the pulse is deep and slow. The external manifestation is spontaneous panting. In Shishui, the pulse is naturally deep. The external manifestation is abdominal fullness without panting. In Huanghan, the pulse is deep and slow, accompanied by fever, chest fullness, and edema of the limbs, head, and face. If untreated for a long time, it will inevitably lead to sores and pus.
The "water" discussed in this chapter, along with "dampness" in the second chapter and "fluid retention" in the preceding twelve chapters, seems to share a common etiology. However, they are listed as three separate categories because there are inherent distinctions. Generally, when there is no morphological form of fluid retention but only the presence of Qi, it is called "dampness." When dampness aggregates into a tangible form, it is called "fluid retention" or "water." Dampness arises from sweat Qi stagnating in the hair follicles (Xuanfu); thus, dampness should theoretically remain only at the Xuanfu. However, sweat is transformed from the vigorous essence of the Stomach. This humid heat Qi, once leaving the Zang-Fu organs but before exiting the skin, can generate dampness anywhere. This explains why after using diaphoretic formulas, one must use formulas like Wuling San (Five-Ingredient Powder with Poria) or Zhuling Tang (Polyporus Decoction) to drain residual sweat Qi. It also explains why Gegen Tang (Kudzu Decoction) remains the primary formula for dampness disorders. This indicates that dampness is already-formed body fluids that have transformed into sweat but cannot be excreted, nor can they revert to normal body fluids. As for water and fluid retention, they seem indistinguishable. Yet, Zhang Zhongjing's intent was that ingested liquids stagnating in the intestines, unable to descend, float upward and expand laterally. Conditions such as Tan (Phlegm), Zhi Yin (Branch Fluid Retention), Xuan Yin (Hanging Fluid Retention), and Yi Yin (Overflowing Fluid Retention) represent diseases where the ingested liquid has not changed form before becoming pathological; hence, they are called "fluid retention." Water disorders, however, involve progression from the Stomach to the Small Intestine and Bladder. Due to difficult urination, and since the Bladder is the Fu organ of the Taiyang channel, which governs the meridians, exterior, and skin, the water Qi floats upward and expands outward from the Taiyang Fu organ to the Taiyang meridian regions. Although water disorders originate from fluid retention, by this stage, they have transformed into the state of "water," hence the name. Among fluid retention disorders, only Fuyin (Hidden Fluid Retention) is similar to water. Thus, when discussing fluid retention, references to Fei Shui (Lung Water) occasionally appear.
Fengshui occurs when wind pathogens of the three seasons invade the Wei (Defensive) level. The Wei Qi becomes strong; this strength causes Yin water Qi from below to ascend and adhere to it. Pishui occurs when the meridians are deficient externally, and urination is difficult downward. The water pathogen in the lower part becomes substantial, attracting the deficiency of the external collaterals, causing water to move through the skin. Zhengshui refers to water residing in its normal pathways, such as in the intestines and stomach. Shishui is named for its sinking and heavy sensation, resembling stone. Huanghan is described in Article 30: sweating while bathing in cold water allows water to enter the pores. Cold water stimulates and submerges the Wei Qi, depriving it of its enveloping power. Consequently, damp-heat Qi overflows externally, producing yellow sweat. These five conditions are all caused by water and have similar symptoms, hence they are discussed together.
When the Taiyang channel is affected by wind, the Wei Qi becomes suspended and strong. Water Qi in the Bladder does not descend but steams upward into the meridians, resulting in a floating pulse. The interaction between wind and water leads to obstruction of Yin Qi and congestion of Yang Qi, causing bone and joint pain. Aversion to wind occurs because wind pathogens penetrate each other, and external wind directly invades the hair follicles after the Wei Qi has been compromised. Pishui involves steaming upward from the Bladder, sharing the same mechanism as Fengshui, except for the absence of external wind pathogens. Hence, the pulse is also floating. [Text missing, likely referring to ankle bone]. Edema is the response of water in the lower Jiao overflowing outward. Indentation upon pressing indicates water reaching the skin, with severity increasing downwards. Absence of aversion to wind confirms the lack of wind pathogens. Abdominal distension like a drum indicates water affecting the interior more severely than the exterior. Absence of thirst suggests neither heat-transforming wind pathogens nor internal rejection by abdominal water. Inducing sweating is indicated for both Fengshui and Pishui because water in the Wei level and skin layers is best drained via opening the Xuanfu.
Zhengshui results from water moving from the Bladder to the Small Intestine and Stomach, representing a pattern of deficiency-cold and failure of Qi transformation. A deep pulse indicates water; a slow pulse indicates cold. Thus, a deep-slow pulse is appropriate. Water-cold Qi shooting upward causes panting. Shishui presents with a purely deep pulse, indicating water without cold. Abdominal fullness results from water; absence of panting results from absence of cold. However, the classic states that simultaneous deep pulses of Liver and Kidney indicate Shishui; thus, abdominal fullness in Shishui should be located outside the intestines in the Liver-Kidney region, distinguishing it from Zhengshui. In Huanghan, water entering the pores causes a deep pulse. Cold water submerging Wei Qi causes a deep and slow pulse. Stagnant sweat causes fever. Cold water obstructing sweat Qi and forcing it backward into the chest causes chest fullness. The limbs are where Yang Qi is abundant; the head and face are where Yang Qi converges. Stagnation of both water and sweat causes edema. Prolonged stagnation leads to Qi decay, generating sores; Qi decay leads to Blood decay, generating pus.
Article 2 A floating and surging pulse. Floating indicates wind; surging indicates Qi. Wind and Qi battling each other: if Wind is stronger, it causes hidden rashes and body itching. Itching is termed "Xiefeng" (Leaking Wind); prolonged cases develop crusts and scabies. If Qi is stronger, it causes water retention, making flexion and extension difficult. If Wind and Qi strike each other violently, severe body edema occurs; recovery follows sweating. Aversion to wind indicates deficiency, classifying this as Fengshui. Absence of aversion to wind, with free urination, cold in the Upper Jiao, and excessive salivation, classifies this as Huanghan.
The pulse description refers to the whole body, as subsequent articles specify parts. Wind is a Yang pathogen with ascending nature; a floating pulse indicates wind invading the Wei level. Qi belongs to the Yang division; excess manifests as fire; a surging pulse indicates Qi stagnation at the exterior. Wind and Qi battling means wind lifts Qi (making it more floating) and Qi drums Wind (making it more surging). "Strong" implies rigidity. Strong Wind dries the blood and causes dry-heat in the meridians, leading to hidden rashes and itching. Since there is insufficient blood to expel the pathogen, wind leaks out, causing itching ("Wind Leakage"). Prolonged itching leads to sores and scabies. Strong Qi implies Yang failing to hold inward and erupting; water replaces Ying-Yin and ascends, resembling dragon-water attraction, causing water retention. Difficulty in movement results from water, wind, and Qi battling in the meridians, causing severe edema. Sweating disperses wind, water, and Qi through the pores, normalizing the pulse and curing the disease. If aversion to wind is added, it indicates severe Wei Qi deficiency; nourishing Yin and tonifying Yang should be added to diaphoretics. This is the typical presentation of Fengshui. The five sentences regarding "no aversion to wind" specifically address edema, not the entire syndrome. Body edema without aversion to wind lacks wind etiology; free urination lacks water etiology. Cold in the Upper Jiao with excessive saliva indicates cold-water Qi entering the chest via pores, impairing Lung distribution of fluids. This is Huanghan, not Fengshui. Article 30 describes Huanghan as resembling Fengshui; thus, differentiation is necessary here.
Article 3 A deep and slippery pulse at the Cun Kou (Radial artery) indicates internal water Qi. Swelling of the face and eyes with fever is named Fengshui. Observing slight swelling above the eye sockets, resembling a silkworm just waking up, pulsation of the neck vessels, frequent coughing, and pitting edema on the hands and feet that does not rebound immediately confirm Fengshui.
The previous article discussed generalized Fengshui; this article focuses on the upper body. Cun Kou corresponds to the head/eyes internally and the Wei exterior externally. A deep pulse indicates submerged Qi; a slippery pulse indicates gathered water. Wind has harmed the Upper Jiao and Wei Qi, causing them to sink, allowing water Qi to rise and expand. This initial sign indicates internal water Qi. "Middle" here does not mean interior but implies that even before full edema appears, these subtle signs allow prediction. The symptoms described are exterior, not Zang-Fu related. Combining pulse and symptoms: facial swelling corresponds to Cun Kou. Deep pulse means Yang Qi sinks; slippery pulse means Yin Qi rises. This describes the water etiology. Fever with a deep-slipse pulse suggests Yang pathogenic wind transforming into heat. The following six sentences elaborate on the earliest signs based on the deep-slipse pulse. One need not wait for full facial swelling or fever; these signs suffice. Swelling above the eye socket (upper eyelid) resembles a silkworm shedding skin, bright and watery. This area is active and gathers Yang Qi. Slight swelling indicates wind harming weak Yang, allowing water to invade. Neck vessel pulsation refers to the Renying point (ST9), distributing Stomach Qi to the head. Agitated pulsation indicates wind and water pathogens obstructing ascending Qi. Lung rebellion causes coughing due to wind-water invading the Wei and flooding the chest. Hands and feet are the extremities of Yang. Weak Yang retreating inward allows water to invade first, causing edema. Non-pitting edema indicates Qi edema (formless, rebounds quickly); pitting edema indicates Water edema (tangible, rebounds slowly). Early diagnosis prevents progression. A student asked: Why does water rush to wind? What path does it take? Why do Articles 2 and 3 show different pulses (floating-surging vs. deep-slippe) for the same condition? The answer uses analogy: Wind rising, sun fading, clouds gathering, rain forming—this is Fengshui. Water evaporating to clouds, clouds condensing to rain—Qi movement mirrors water transformation. The pulse differences reflect Wei Qi strength. Strong Wei battling wind externally yields floating-surging pulse (Yang brightness); weak Wei hiding from wind internally yields deep-slippe pulse (Yin obscurity). Zhang Zhongjing’s work reveals the mysteries of Heaven and Earth.
Article 4 Taiyang disease with a floating-tight pulse typically presents with bone/joint pain. If there is no pain but instead heaviness and numbness, and no thirst, sweating cures it; this is Fengshui. Chills indicate extreme deficiency caused by improper sweating. Thirst without chills indicates Pishui. Body edema with coldness, resembling Zhoubi (generalized bi-syndrome), chest oppression, inability to eat,集聚 pain, evening restlessness, and insomnia indicate Huanghan. Pain in joints with cough/panting and no thirst indicates Pi Zhang (Spleen Distension), resembling edema, cured by sweating. However, if patients with these conditions have thirst plus diarrhea or frequent urination, sweating is contraindicated.
Taiyang disease encompasses symptoms like stiff neck. Floating-tight pulse usually means wind-cold blocking bone Qi, causing pain. Heaviness stems from water; numbness from wind. Spleen and Lungs dislike dampness; water stagnation causes heaviness. Joints prefer freedom; wind stagnation causes numbness. Tight pulse reflects floating cold-water Qi in Taiyang. No thirst indicates mild wind and strong water rejection. Sweating resolves both wind and water. This differs from Article 2 (heavy wind and water); here, water exceeds wind, explaining lack of joint pain and presence of heaviness/no thirst. Chills refer to pre-disease state: prior sweating weakened Wei Qi and opened pores, inviting wind and water. Article 1 mentions aversion to wind; Article 2 links aversion to wind with deficiency; Article 4 links chills with extreme deficiency from sweating. Some Fengshui cases have aversion to wind (wind opens pores); others do not (strong Wei battles wind externally, causing surface excess). Extreme deficiency causes both wind and cold aversion, treated with Huangqi (Astragalus) or Fuzi (Aconite) as per Articles 24-25. Article 1 says Pishui has no thirst; Article 4 says Pishui has thirst. This is not contradictory. Pishui from intestinal heat with poor urination causes thirst (heat steaming). Pishui from cold intestines due to purgative abuse causes no thirst (cold water rejecting internally). See Article 6 note. Articles 1 and 4 contrast Fengshui/Pishui symptoms to differentiate them. Zhengshui and Shishui are omitted because Pishui often originates from them. Water and sweat competing at the exterior cause edema; cold water submerging Wei Qi causes coldness. Zhoubi shares similarities with Huanghan (weak Qi, external pathogen, internal Yang depression). Chest oppression and anorexia relate to Upper Jiao dysfunction.集聚 pain in the evening results from Yin dominance meeting cold-water pathogen, disturbing weak Yang. Huanghan is differentiated from Pi Zhang: joint pain/cough/no thirst indicates Pi Zhang (Spleen distension affecting Lung), not Huanghan. Spleen-Lung interaction failure causes edema, joint pain, and cough. Lung fluid stagnation causes no thirst. Sweating cures all five conditions mentioned. However, sweating is contraindicated if thirst accompanies diarrhea or frequent urination, as Qi and fluids are already depleted downward; sweating would deplete remaining Qi and Blood. Note: "Frequent urination" in Shanghan/Jingui usually means difficult urination, but here it implies free, frequent urination.
Article 5 Li Shui (Interior Water) presents with yellow edema of the whole body and face, deep pulse, and difficult urination, causing water disease. If urination is free, it indicates loss of body fluids causing thirst. Yuebi Jia Zhu Tang (Yuebi Decoction plus Atractylodes) is indicated.
Yuebi Jia Zhu Tang Formula: Mahuang (Ephedrae Herba, 6 liang), Shigao (Gypsum Fibrosum, 0.5 jin), Gancao (Glycyrrhizae Radix et Rhizoma, 2 liang), Shengjiang (Zingiberis Rhizoma Recens, 2 liang), Dazao (Jujubae Fructus, 15 pieces), Baizhu (Atractylodis Macrocephalae Rhizoma, 6 liang). Boil the six ingredients in 6 sheng of water. First boil Mahuang, remove foam. Add other herbs. Boil to 3 sheng. Divide into three warm doses.
Li Shui originates from Zhengshui/Shishui in the intestines, liver, and kidneys, with massive internal water spreading outward. Unlike Fengshui/Pishui (external deficiency attracting water), Li Shui is internal origin. Yellow color indicates water overflowing earth; edema indicates water lifting Qi. Swelling from lower body to face indicates ascending water. Deep pulse and difficult urination confirm internal accumulation and external overflow. If urination is free despite edema, it indicates prior damage to fluids (via sweating/vomiting/purging), causing thirst and compensatory water absorption. Treatment should focus on fluid restoration, not diuresis. Yuebi Jia Zhu Tang is used because Wei Qi is not deficient, but water fills the Ying level. Mahuang induces sweating to drain water. Stagnant water causes heat (root of yellowing); Shigao clears heat and calms aggression. Although Li Shui, the upper/exterior symptoms are urgent. Gancao supports upward/outward movement. Shengjiang promotes Yang; Dazao nourishes fluids. This protects Qi and Blood during sweating. Baizhu removes residual dampness, acting like rear-guard troops securing peace. The formula is precise for free urination with edema. For the upper section described as Li Shui with difficult urination...
