黄帝问曰。有病温者。汗出辄复热。而脉躁疾。不为汗衰。狂言不能食。病名为何。岐伯对曰。病名阴阳交。交者

谷生于精。（汗生于水谷之精。水谷之精。由精气之所化。故曰谷生于精。夫汗之发原有二。一出于水谷之精。一出于肾

Huangdi asked, "There is a patient suffering from a warm disease. After sweating, the fever returns immediately, and the pulse is rapid and restless, not subsiding with the sweat. The patient also exhibits delirium and an inability to eat. What is this disease named?" Qibo replied, "This disease is called 'Yin-Yang Jiao' (Crossing of Yin and Yang). 'Jiao' implies death. (Warm diseases arise from cold injury in winter; those manifesting before the Summer Solstice are termed warm diseases. 'Yin-Yang Jiao' refers to the phenomenon where sweat, being Yin fluid, exits to the exterior (Yang), but the Yang heat pathogen does not resolve with the sweat but instead re-enters the Yin. This crossing signifies that the healthy Qi cannot overcome the pathogenic factor, and the pathogen subsequently damages the healthy Qi, resulting in a fatal condition.)" Huangdi said, "I wish to hear the explanation." Qibo said, "The reason humans sweat is that it all originates from grain (food and drink). Grain essence generates Jing (Essence). (Sweat is generated from the essence of water and grain. The essence of water and grain is transformed by Jing essence, hence it is said that 'grain generates Jing'. There are two origins for sweat: one comes from the essence of water and grain, and the other from the Jing stored in the Kidney. When it is said that 'all originate from grain', it means that the Jing stored in the Kidney is also produced by water and grain.) Now, if pathogens and healthy Qi contend between the bones and muscles and sweat occurs, this indicates that the pathogen is retreating and the Jing has prevailed. (Contending between bones and muscles means the pathogen hides between them. In spring, it contends with healthy Qi, causing warm disease. Sweating indicates that Jing prevails, and the pathogen should exit together. Ni Chongzhi stated: The Stomach governs flesh, and the Kidney governs bones. Sweat from stomachal grain essence differs from sweat originating from kidney blood essence. If the pathogen is in the flesh, it resolves with grain sweat; if in the bones, it requires kidney Jing sweat to resolve.) When Jing prevails, the patient should be able to eat and not have recurrent fever. Recurrent fever indicates the presence of the pathogen; sweat represents Jing essence. Now, sweating followed immediately by fever indicates the pathogen has prevailed. The inability to eat means there is no supplementation for the Jing. If the disease lingers, life will end abruptly. (This explains that the essence of water and grain is transformed by Kidney Jing. The Kidney is the Water Organ, receiving and storing the essence of water and grain. Its Jing ascends to combine with the Yangming channel. Wu and Gui combine to transform into Fire; the Qi of Fire and Earth digest the essence of water and grain to regenerate this Jing, illustrating the mutual nourishment of the Pre-Heaven and Post-Heaven sources. Now, after sweating, if the pathogen lingers, the heat pathogen will damage the Yin Jing again. Damaged Jing cannot combine with Yangming to aid digestion, meaning the source of Jing generation is cut off, and life will end instantly. Dong Weiyuan noted: The way of mutual growth rotates like a ring.) Furthermore, the *Lun* on Heat states: 'If the pulse remains rapid and vigorous after sweating, death ensues.' (This cites the *Lun* on Heat to explain the meaning of 'sweat originates from grain, grain from Jing, inability to eat, and lack of Jing supplementation'. The *Ling Shu: Lun on Heat* states: 'In heat disease, if sweat occurs but the pulse remains rapid and vigorous, this is the extreme of the Yin pulse, indicating death. If the pulse becomes calm after sweating, survival is indicated. If the pulse is rapid and vigorous but no sweat occurs, this is the extreme of the Yang pulse, indicating death. If the pulse is full and rapid but becomes calm after sweating, survival is indicated. Sweat is Jing essence. Rapid and vigorous pulse after sweating means the pathogen is strong and Jing is insufficient. The Yin pulse refers to the Shaoyin pulse; 'extreme' means termination. This indicates Shaoyin Qi is terminated due to intense heat pathogen. Rapid pulse without sweat indicates excessive Yang heat and exhaustion of Stomach Qi.) Now, the pulse does not correspond with the sweat (i.e., the pulse remains rapid despite sweating); this shows the healthy Qi cannot overcome the disease. Death is evident. Delirium indicates loss of Zhi (Will/Shen), and loss of Zhi leads to death. (Pulse not corresponding to sweat indicates deficient Stomach Qi unable to resist the pathogen, implying imminent Stomach Qi exhaustion. The Kidney stores Zhi. Delirium indicates Jing injury and premature death of Zhi. Premature death of Zhi results in death within one and a half days.) Now, three signs of death are present, with no sign of life. Even if temporary recovery occurs, death is inevitable. (Lingering disease is one sign of death; exhausted Stomach Qi is another; exhausted Kidney Qi is the third. The Kidney is the root of living Qi. If sweat fails to overcome the pathogen but Kidney Jing remains, there is a chance for life. If Jing is injured but Yangming's generative source is intact, there is a chance. 'Recovery' here means the pathogen is gone. If the pathogen is gone but the source of living Qi is exhausted, death is certain. The above discusses the principles of pathogen vs. healthy Qi and Yin-Yang, emphasizing the importance of protecting the generative source of healthy Qi.)" Huangdi asked, "There is a disease characterized by body heat, sweating, and vexation/fullness, where vexation/fullness does not resolve with sweating. What is this disease?" (Note: This chapter discusses how Yang heat pathogens are countered only by Yin Jing. Sweat is Jing essence, originating either from water/grain essence or Kidney fluids. Water/grain enters the Stomach, fluids distribute, and sweat flows profusely—this is water/grain essence. The Kidney is the Water Organ, storing essence from the five Zang organs. This essence transforms into blood via the Heart; the fluid of blood is sweat—this is Kidney essence. Thus, the previous section discussed sweat from grain, and this section below discusses wind damaging Kidney Jing. Wind causes water to disperse; overflowing water leads to deficiency of Jing. This section discusses wind moving Kidney Jing; the Lao Feng section discusses wind moving Kidney water Qi; the Shen Feng section discusses wind moving Kidney water pathogen—all ultimately belonging to deficiency of both Jing and Qi.) Qibo said, "Sweating with body heat is due to Wind. Sweating with unresolved vexation/fullness is due to Jue (Reversal). The disease is named 'Feng Jue' (Wind Jue). (Wind is a Yang pathogen that opens the muscle interstices. Sweat from the interstices is water/grain essence. Fluid leakage allows wind-heat to linger, causing body heat. Lingering wind-heat damages Kidney Qi, causing it to rebel upward. Upward rebellion causes heart vexation; attacking Spleen earth causes middle jiao fullness. Named 'Feng Jue' because wind causes Kidney Qi reversal. The previous section discussed death when healthy Qi is exhausted despite apparent recovery; this section discusses survival when the root remains intact despite lingering pathogen. The reality/deficiency of pathogen and healthy Qi determines life and death significantly; students must examine this carefully.)" Huangdi said, "I wish to hear the complete details." Qibo said, "Ju Yang (Taiyang) governs the exterior Qi and thus receives the pathogen first. Shaoyin is its interior-exterior pair.受热 (receiving heat) causes it to follow upwards; following upwards leads to Jue. (Ju Yang is Taiyang. Taiyang Qi governs the exterior. Wind is a Yang pathogen damaging Yang Qi. Two Yangs clashing cause heat disease. Shaoyin and Taiyang are interior-exterior pairs. Yang heat above causes Yin Qi to follow it up; following up results in Jue.)" Huangdi said, "How should it be treated?" Qibo said, "Needle both the exterior and interior channels, and administer decoctions. (Exterior and interior refer to Yin and Yang. Needling the exterior drains the Yang pathogen of wind-heat; needling the interior descends the rebellious Qi of Shaoyin. Administering decoctions assists in generating fluid-Jing sweat.)" Huangdi asked, "What about Lao Feng (Labor-induced Wind) disease?" (This discusses labor-induced sweating exposed to wind, injuring the Kidney. Vexation/labor causes Yang Qi to expand outward and Jing to deplete inward. Exterior Yang deficiency makes one susceptible to wind; interior Jing deficiency agitates water Qi.) Qibo said, "Lao Feng typically manifests below the Lung. (Wind moves cold-water Qi, which should reside below the Lung. *Shui Re Xue Lun* states: The Kidney is Supreme Yin, holding water; the Lung is Taiyin; Shaoyin is the Winter pulse. Thus, the root is in the Kidney, the branch in the Lung, both involving water accumulation.) Its symptoms include stiffness of the head and neck, and blurred vision. (Stiffness arises because Yang expands and wind strikes again, causing upper stiffness. Jing depletion and further injury cause blindness/blurred vision.) The patient spits phlegm resembling mucus, fears wind, and shivers with cold. This is Lao Feng disease. (Kidney fluids enter the Lung to become mucus; exiting the mouth is saliva. Wind moves Kidney water to the Lung base, causing spit resembling mucus. The Lung governs skin/hair; wind-cold invading the Lung causes fear of wind and chills. This occurs when one exerts oneself vigorously and labors heavily, causing Kidney sweat, which then encounters wind.)" Huangdi said, "How should it be treated?" Qibo said, "Rescue the ability to bend and extend. (*Jin Gui Yao Lue: Water Qi Chapter* states: Excessive Qi creates water, making bending and extension difficult. Cold-water Qi rebels upward, carrying有形 (form) water with it. One must urgently rescue the water pathogen to prevent upward overflow causing immobility.) If Taiyang Qi can guide Jing downward for urination, recovery takes three days; middle-aged individuals take five days; those with deficient Jing (elderly) take seven days. (This describes the method for restoring mobility, which should exit via urine. 'Taiyang guiding Jing' refers to the Bladder Fu, which stores fluids and excretes them upon Qi transformation. Strong Taiyang Qi guides Kidney pathogenic water out via urine, curing in three days. Middle-aged people with deficient Jing take five days; elderly with declining Jing take seven days. Three, five, and seven are Yang numbers, indicating that with Yang transformation, Yin water naturally exits.) If the patient coughs up green-yellow phlegm resembling pus, size of a bullet, exiting via mouth or nose, failure to expel it injures the Lung, leading to death. (This describes expelling cold-water pathogen rebelling below the Lung via the upper orifices, a method of draining from top and bottom. The Kidney is the Water Organ, storing essence from the five Zang. Now, Kidney water rebels upward, causing fluids of the four Zang to coagulate rather than descend. Green-yellow phlegm represents Liver/Spleen fluids; pus-like substance represents Heart/Lung fluids. Since these fluids do not descend to the Kidney but accumulate below the Lung, they must be coughed out. The Lung is above the Spleen. Exit via mouth (Spleen connection) or nose (Lung connection) are the external orifices for phlegm/saliva. The Lung is pure and empty; pathogenic turbidity injuring it causes death.)" Huangdi asked, "There is a patient with Shen Feng (Kidney Wind), presenting with facial edema and obstructed speech. Can acupuncture be used?" ('Qiu' refers to the cheekbone/foot swelling; 'Run' means swelling. Facial and foot edema. Shaoyin meridian passes through the Kidney and connects to the tongue root. Water pathogen rebels upward, obstructing speech.) Qibo said, "Deficiency patterns should not be needled. If needled inappropriately, the pathogen will arrive in five days. (Kidney damaged by wind has deficient Jing/Qi, so needling is contraindicated. Needling deficiency causes rebellious Qi to arrive in five days. *Ping Mai Pian* states: Weak Kidney Qi and scant Jing/blood cause rushing Qi entering the chest/diaphragm. Deficient Jing allows water pathogen to rebel upward. Five days refers to the pathogen starting in Taiyang and reaching Shaoyin to move Qi after five days.)" Huangdi asked, "What will happen when it arrives?" Qibo said, "It will definitely present with shortness of breath, intermittent fever, sweating, hot hands/feet, dry mouth with bitter taste and thirst, yellow urine, edema under the eyes, abdominal borborygmi, heavy body with difficulty walking, amenorrhea, vexation with inability to eat, inability to lie flat (supine position causes coughing). The disease is named 'Feng Shui' (Wind-Water). Discussion is in the *Ci Fa* (Acupuncture Methods) chapter. (Named Feng Shui because wind moves water. 'In Ci Fa' refers to the *Shui Re Xue Lun* chapter.)" Huangdi said, "I wish to hear the explanation." Qibo said, "Where the pathogen gathers, the Qi is necessarily deficient. Where Yin is deficient, Yang inevitably gathers. Hence, shortness of breath, intermittent fever, and sweating occur. (Wind damages the Kidney, causing Jing deficiency. Yin deficiency allows Yang to invade, causing intermittent fever. Kidney is the root of living Qi, hence shortness of breath. Yang added to Yin causes sweating. Damp-heat steams upward from chest/back to head. Heat in Lower Jiao causes yellow urine. Ni Chongzhi stated: Taiyang and Shaoyin share root/branch. Wind damages Kidney, starting in Taiyang, progressing to Kidney. Kidney heat steams upward along Taiyang Qi to the head.) Inability to lie flat is due to Stomach disharmony. Supine position worsens coughing because Qi presses on the Lung. (This clarifies Yang pathogen injuring Yin and moving Kidney water. 'Zheng Yan' is supine. Water rising to Stomach causes disharmony, preventing supine posture. Lung meridian connects to Large Intestine and circles the Stomach, so Qi presses on Lung. Previous section discussed Yang heat injuring Jing; this section discusses moving water. Ni Chongzhi stated: Lao Feng accumulates below Lung, producing lung fluid (phlegm), not Kidney water. Lung is the source of water; reversed Kidney Qi condenses water above. Supine pressing on Lung is due to Stomach Qi rising, not Kidney water. Edema under eyes is abdominal water pathogen manifesting below eyes. Note that Kidney deficiency with water flooding only reaches the abdomen.) All patients with water Qi exhibit slight edema, first appearing under the eyes. Huangdi asked, "Why?" Qibo said, "Water is Yin; under the eyes is also Yin. The abdomen is the residence of Supreme Yin. Thus, water in the abdomen causes edema under the eyes. (Taiyin is Supreme Yin. Water pathogen rises to abdomen, injuring Stomach then Spleen. Slight edema appears first under eyes. Spleen binds. Ni Chongzhi stated: Water in abdomen, edema under eyes, is due to water Qi.) True Qi rebels upward, causing bitter taste and dry tongue. (True Qi refers to the Heart Qi of the Zang. Heart is Fire and dislikes water. Water rising forces Heart Qi to rebel, causing bitterness and dryness.) Inability to lie flat; supine position causes coughing up clear water. (This describes water rising from Stomach to Spleen, Heart, and Lung. Kidney is root, Lung is branch; Metal/Water mother-child organs both hold water. Water rebelling to Lung causes coughing clear water.) All water disease patients cannot lie down; lying down causes fright, and fright worsens coughing. (Kidney pathogen rises to Stomach, pressing on Heart. Stomach Qi pressing on Heart forces Heart Qi onto Lung. Water in Stomach prevents lying down. Stomach meridian connects to Heart; Yang entering Yin causes Yin-Yang conflict, leading to fright. Heart Qi pressing on Lung causes Metal to fear Fire, worsening cough. Previous section discussed water rising from below; this section discusses Zang-Fu Qi also rising from below.) Abdominal borborygmi originates in the Stomach. (Water pathogen enters meridians, circulating downwards. Water disease starts in Stomach, draining via meridians, causing rumbling. Pressing Spleen causes vexation/anorexia. Spleen meridian connects to Heart, causing vexation. Upper Jiao governs intake, causing anorexia. Stomach obstruction prevents eating. Water flowing down causes heaviness. Ni Chongzhi stated: Pathogen only attacks Stomach; pressing Spleen/Lung/Heart is secondary Stomach Qi movement, not direct water attack on Heart. Kidney is the gate of Stomach; water exits gate, pathogen stays in Stomach, hence 'originates in Stomach'.) Amenorrhea is due to closure of Bao Mai (Uterine vessels). Bao Mai belongs to the Heart and connects to the Bao (Uterus). Now, Qi presses on the Lung, preventing Heart Qi from descending, hence amenorrhea. Huangdi said, "Excellent." (Fluids of Middle Jiao flow to Kidney as Jing, transform to blood via Heart. Blood fluid is sweat. This section begins with wind damaging Kidney Jing and ends with failure to transform to blood. This chapter evaluates Yang heat pathogens, stating they are countered only by Yin Jing/sweat. Previous chapter stated death if grain-sweat fails to overcome pathogen; here, Kidney Jing damaged by wind and unable to receive Heart Qi to transform to blood means wind cannot exit via sweat. Regarding Ying Qi: Grain enters Stomach, transmits to Lung, flows internally, distributes externally. Refined essence nourishes meridians continuously. Blood is Middle Jiao fluid flowing in meridians and seeping into skin, having two paths. Middle Jiao extracts juice, changes to red—this is refined blood in meridians. Flowing internally/distributing externally is blood in Bao and skin. Bao Mai belongs to Heart, becoming blood via descending Heart Qi. Chong and Ren meridians originate in Bao, ascend back, serving as Sea of Meridians. Floating/exterior branches ascend right abdomen to throat, connect lips/mouth. Abundant Qi/Blood fills skin/flesh; abundant Blood seeps into skin, growing hair. Men grow beard at lips; women menstruate at chest. Blood fluid as sweat is seeped skin blood, not meridian blood.
