The *I Ching* discusses Heaven and Earth, stating that from the Great Void to the Yellow Springs, there are six positions. The *Huangdi Neijing* (Yellow Emperor’s Inner Canon) states that the human body, from head to foot, also has six positions. Now I further observe that from the Lung to the Kidney, there are again six positions. Humans and the creation of Heaven and Earth share the same Five Elements, like being smelted in one furnace; knowing one allows you to know the other. Thus, the Qi establishing Heaven is Metal and Fire; the Qi establishing Earth is Earth and Water; the Qi establishing Humanity is Wind and Fire. Therefore, when Metal and Fire combine, they are hot yet clear; when Earth and Water combine, they are damp yet cold; when Wind and Fire combine, they are warm yet blazing. The area between the chest and abdomen of humans is likewise. The Lung is at the very top, belonging to Metal and governing Dryness; the Heart follows, belonging to Sovereign Fire and governing Heat; the Liver follows, belonging to Wind-Wood and governing Warmth; the Gallbladder follows, belonging to Ministerial Fire and governing Extreme Heat; the Spleen follows, belonging to Damp-Earth and governing Coolness; the Kidney follows, corresponding to the Yellow Springs, belonging to Cold-Water and governing Cold. Thus, the Heart and Lung resemble Heaven, the Spleen and Kidney resemble Earth, and the Liver and Gallbladder resemble Humanity. Those who do not understand this cannot discuss human diseases with them. Earth is the root of all things, and Water is the origin of all things. Earth and Water unite in virtue, occupying Yin positions in Yin, dwelling together below, thereby establishing Earth as Qi. All things take root in Earth; therefore, Earth and Water are damp and cold. If Dryness-Heat and Yang-Excess prevail, the Qi of Earth cannot be established, the roots of all things will lack moisture, and branches and leaves will wither.
The *Suwen · Wu Chang Zheng Da Lun* (Great Treatise on the Five Constants and Normal Policies) says:
"Middle" is called Shenji (Spirit Mechanism). This refers to animals, whose root lies in the middle. The root refers to the Spleen, Stomach, and Kidney. When food enters the Stomach, the Spleen distributes and transforms its Qi and flavor, nourishing the five Zang organs and hundred bones. Thus, Sour enters the Liver and nourishes tendons and fascia; Bitter enters the Heart and nourishes blood vessels; Sweet enters the Spleen and nourishes muscles; Pungent enters the Lung and nourishes skin and hair; Salty enters the Kidney and nourishes bone marrow. The same applies to the Five Qi. Thus, Clear Qi nourishes the Lung, Heat nourishes the Heart, Warmth nourishes the Liver, Dampness nourishes the Spleen, and Cold nourishes the Kidney. Regarding these Five Flavors and Five Qi, excess causes disease, deficiency also causes disease; only balance ensures constant health. Thus, the *Suwen · Liu Jie Zang Xiang Lun* (Treatise on the Six Nodes and Viscera Manifestations) says: "When Five Flavors enter the mouth, they are stored in the intestines and stomach... storing them to nourish the Five Qi. When Qi is harmonious, life arises; when fluids and liquids form together, Spirit naturally generates." This is the principle. Furthermore, the *Suwen · Tai Yin Yang Ming Lun* (Treatise on Taiyin and Yangming) asks: "Why does the Spleen fail to function when diseased?" Qibo replies: "The four limbs all receive Qi from the Stomach, but cannot reach the meridians directly; they must rely on the Spleen to receive it. Now, if the Spleen is diseased and cannot transport fluids for the Stomach, it cannot receive Grain-Qi. Qi declines daily, meridians become obstructed, and tendons, bones, and muscles lack Qi to generate, hence they do not function." The Yellow Emperor asks: "Why does the Spleen not govern a specific season?" Qibo replies: "The Spleen belongs to Earth, governs the Center, and constantly nourishes the Four Zang organs throughout the four seasons, presiding for eighteen days at the end of each season; it cannot exclusively govern one season. The substances stored in the Zang organs constantly adhere to the essence of Stomach-Earth. Earth generates all things and models itself on Heaven and Earth. Therefore, from top to bottom, head to foot, it cannot exclusively govern one season."
The Yellow Emperor asks: "The Spleen and Stomach are connected only by membranes, yet they can transport fluids. Why?" Qibo replies: "The Foot-Taiyin (Spleen Meridian) is one of the Three Yin meridians; its vessel penetrates the Stomach, connects to the Spleen, and links to the throat. Thus, Taiyin transports Qi through the Three Yin meridians. The Foot-Yangming (Stomach Meridian) is exterior; it is the Sea of the Five Zang and Six Fu organs, and also transports Qi through the Three Yang meridians. The Zang and Fu organs receive Qi along their respective meridians to benefit Yangming, thus transporting fluids for the Stomach. The four limbs cannot receive Grain-Qi; Qi declines daily, Yin pathways become obstructed, tendons, bones, and muscles lack Qi to generate, hence they do not function. 'Not functioning' means being unable to utilize them. From this, we see that the Five Zang and Six Fu organs, and the four limbs and hundred bones, all receive from the Spleen and Stomach, which transport fluids, mutually moistening and nourishing. Later physicians, wishing to nourish the Spleen and Stomach and tonify Earth-Qi with drying-hot agents, are far off the mark! Moreover, patients with Xiao Ke (Wasting-Thirst) have extreme deficiency of damp-cold Yin Qi and excessive excess of dry-heat Yang Qi. Taking more drying-hot medicines would exhaust Spleen-Stomach Qi. In later ages, people fail to distinguish the excess/deficiency of the Five Movements and Six Qi, generally claiming Heat is Excess and Deficiency is Cold. They only understand the excess/deficiency of Heart-Fire Yang-Heat, not the excess/deficiency of the Six Qi of the Zang organs. Generally, the Lung is originally clear; when deficient, it becomes warm. The Heart is originally hot; when deficient, it becomes cold. The Liver is originally warm; when deficient, it becomes cool. The Spleen is originally damp; when deficient, it becomes dry. The Kidney is originally cold; when deficient, it becomes hot. If 'Stomach Cold' is considered Deficiency, it is actually because Yin-Water Cold Qi is excessive in the Stomach, while Yang-Fire Hot Qi is weak and deficient, not because the original dampness of Stomach-Earth is deficient. Therefore, one should warm and tonify the deficiency of Yang-Fire in the Stomach and reduce the excess of Yin-Water Cold Qi. Conversely, if 'Stomach Heat' is considered Excess, it is because Yang-Fire in the Stomach is excessive and Yin-Water is deficient. Thus, one should use cold medicines to purge the Excess-Fire in the Stomach and nourish the deficient Water. However, these methods address the deficiency-heat in the Stomach caused by Water and Fire invading pathogens, not the original state of Stomach-Dampness. The rest follow similar principles.
Regarding tonifying or purging the Water-Qi of Spleen-Stomach Damp-Earth: Moistening the dampness is tonifying dampness; drying the dampness is purging dampness, because Earth is originally damp.
For all Qi of the Zang and Fu organs, one need not assume Kidney-Water alone corresponds to Cold or Heart-Fire alone to Heat. One must know that for every Zang and Fu, the various Qi should be harmonized, dispersed, and balanced. Thus, I once said: In the Way of the Five Constants, Yin contains Yang, and Yang contains Yin. Solitary Yin does not grow; solitary Yang does not complete. As long as all things are present, the Five Elements mutually support and nourish each other; this is called Peace. Mutual overcoming leads to decline and rise. Disorder and loss of normalcy bring disaster. Therefore, less Water and more Fire result in Yang-Excess and Yin-Deficiency, causing Heat disease; more Water and less Fire result in Yin-Excess and Yang-Deficiency, causing Cold disease. The treatment method is to purge Excess and tonify Deficiency, aiming for balance. Thus, treating Xiao Ke involves tonifying the deficiency of Kidney-Water Yin-Cold and purging the excess of Heart-Fire Yang-Heat, removing severe dry-heat from the intestines and stomach, assisting the decline of bodily fluids, ensuring pathways remain open and unblocked, fluids generate without withering, and Qi and Blood flow smoothly without stagnation; then the disease will heal day by day. Moreover, Xiao Ke originates from improper diet and medication, leading to dry intestines and stomach, preventing the smooth distribution of Qi and fluids; or from mental exhaustion and exceeding limits; or from severe illness damaging Yin Qi and depleting Blood, resulting in fierce Yang Qi and severe stagnation of dry-heat. Thus, *Jizhong Xinbian* (New Compilation for Saving the Masses) states: San Xiao (Three Thirsts) all result from long-term craving for salty foods, indulgence in roasted/fried foods, and excessive alcohol consumption; some young people take metallic/mineral pills causing heat, which accumulates in the chest, creating lower-jiao deficiency-heat where Blood-Qi cannot control the mineral heat, causing extreme dryness in the Stomach, leading to thirst and drinking. If drinking much results in urinating much, it is named Xiao Ke (Wasting-Thirst); if eating much without intense hunger, frequent urination, and gradual emaciation occur, it is named Xiao Zhong (Consuming-Middle); if thirst persists despite continuous drinking, legs emaciate, and urine contains fatty liquid, it is named Shen Xiao (Kidney-Thirst). These three types of Xiao share the same dry-heat pathogenesis, differing only in severity.
I hear that worldly prescriptions often use one formula to treat all three types of Xiao Ke because they consume food/water quickly and crave thirst. However, modern discussions on Xiao Ke often ignore the root cause. They claim Xiao Ke involves Upper Excess-Heat and Lower Deficiency-Cold. Upper Heat causes irritability, thirst, and excessive drinking; Lower Cold causes frequent urination. The root is deficiency of Lower-Jiao Kidney-Water, failing to control Upper-Jiao Heart-Fire, resulting in Upper Excess-Heat and Lower Deficiency-Cold. They also say: Water number is one, the root of things and precursor of Five Elements. Thus, Kidney-Water is the root of humanity and origin of life; it must not be allowed to weaken. If the root is not firm, branches and leaves will not flourish; if Yuan Qi is not solid, the physique will not thrive. Patients with Xiao Ke have extremely cold Lower-Jiao Kidney-Water. If they take cold medicines, Yuan Qi becomes weaker, Lower-Jiao Kidney-Water declines further, Upper-Jiao Heart-Fire becomes hyperactive and difficult to treat. Instead, one should use warm medicines to tonify Yuan Qi. If Lower-Jiao Kidney-Water becomes substantial and overcomes Upper-Jiao Fire, thirst will naturally cease, urination will normalize, and the disease will heal. Such statements contradict Zhang Zhongjing. They sound plausible but violate logic. This error is not new; it has existed for a long time! For instance, Jiang Shi’s *Yao Zheng Bing Yuan* (Causes of Disease in Medicinal Evidence) discusses Xiao Ke, Xiao Zhong, and Kidney-Thirst, stating: "San Jiao and Five Zang are all deficiency-heat, only the Bladder is cold as ice." It also says: "Lower back and Kidney deficiency-cold increase daily." And: "Bladder and Kidneys are cold as a spring." Initially stating San Jiao and Five Zang are deficiency-heat with only the Bladder cold as ice, it later claims the Five Zang are also cold, and Kidney-Water cold is described as deficiency, while remaining heat is also called deficiency. How can Yin/Yang rise and fall work this way? His statements are self-contradictory. While the error seems small, the discrepancy in Cold/Heat and opposite medications cause grave harm! Others argue: Kidney and Bladder belong to Water; deficiency fails to control Fire. Since deficiency cannot control Fire, frequent urination occurs. They believe Excess Water-Qi controls Fire, while Deficiency cannot. Thus, Yang-Excess and Yin-Deficiency cause Heat to dry fluids, leading to scanty, painful urination; Yin-Excess and Yang-Deficiency fail to control Water, leading to profuse, frequent urination. Do they not realize that frequent urination in Xiao Ke is not due to this? Why? Because extreme dry-heat causes obstruction and stagnation in the pores of the San Jiao and intestines/stomach, making them dense and blocked. Fluids cannot渗泄 (seep and discharge) or moisten externally to nourish the body. Thus, external dry-heat is extreme; even with heavy internal drinking, it cannot moisten externally, so thirst persists. Frequent urination occurs because, despite heavy drinking, fluids cannot seep outside the intestines/stomach, leading to frequent voiding. Therefore, I elaborate in *Yuan Bing Shi*: Skin sweat pores are called Han Kong (Sweat Holes), gateways for sweating. Also called Qi Men (Qi Gates), portals for Qi release. Also called Culi (Interstices), tunnels for Qi and fluid textures. Also called Gui Men (Ghost Gates), gates to the netherworld. Also called Xuanfu (Dark Mansions), mansions of subtlety. Xuanfu exists in everything. Human Zang/Fu organs, skin/hair, muscles/fascia, bone marrow, and all things possess them; they are the pathways for entry/exit and ascent/descent. Thus, the Classics state: "If entry/exit ceases, the Spirit Mechanism perishes; if ascent/descent stands alone, it is perilous." Without entry/exit, there is no growth, strength, aging, or death; without ascent/descent, there is no growth, transformation, storage, or collection. Thus, entry/exit and ascent/descent exist in all vessels. We know that the eyes, ears, nose, tongue, body, mind, spirit, and consciousness function only because of smooth ascent/descent and entry/exit. Obstruction prevents function. If eyes cannot see, ears cannot hear, nose cannot smell, tongue cannot taste, tendons atrophy, bones bi, nails recede, teeth rot, hair falls, skin loses sensation, or intestines/stomach fail to secrete, all are caused by stagnant Heat blocking Xuanfu, preventing Jin Ye (Body Fluids), Blood Vessels, Ying-Wei (Nutritive-Defensive) Clear Qi from ascending/descending and entering/exiting. Depending on the severity of stagnation, diseases vary in magnitude. Exterior diseases involve stagnation, closed interstices, Yang Qi unable to disperse, causing dryness without sweat, preventing Qi/fluid exit. Modern physicians do not understand this; seeing frequent urination in Xiao Ke, they wrongly attribute it to Lower-Jiao Cold. Do they not know that intestinal/stomach dry-heat stagnation causes this? I cite this because worldly views on Xiao Ke attribute it to external intestinal/stomach dry-heat blocking secretion pathways. Although water enters the intestines/stomach, it cannot seep out, causing frequent urination followed by renewed thirst. These few sentences fully explain the principle. Consider cases: Some attribute thirst to Heart/Lung Qi Jue (Reversal); some to Liver Bi (Obstruction); some to Spleen Heat; some to Kidney Heat; some to Stomach/Large Intestine Heat Binding; some to Spleen Bi; some to Small Intestine Dan Heat; some to Malaria; some to rich/greasy/mineral drugs; some to drunkenness/coitus; some to travel fatigue in extreme heat; some to Stomach dryness injury; some to Kidney Heat; some to Wind disease. Although Zang locations differ and pathogenic encounters vary, the outcome is always Dry-Heat.
Regarding Heart/Lung Qi Jue causing thirst: The *Jue Lun* (Treatise on Reversal) states: "Heart transfers Heat to Lung, transmitting as Ge Xiao (Diaphragm Thirst)." Commentary: "Heart Heat enters Lung, transmits over time, internally forming Diaphragm Heat-Fluid." Regarding Liver Bi causing thirst: The *Bi Lun* (Treatise on Bi) states: "Liver Bi involves night terrors, excessive drinking, frequent urination." Regarding Spleen Heat causing thirst: The *Wei Lun* (Treatise on Flaccidity) states: "Spleen Heat causes Stomach dryness and thirst, muscle insensitivity, developing into Rou Wei (Muscle Flaccidity)."
Regarding Kidney Heat causing thirst: The *Ci Re Lun* (Treatise on Acupuncture for Heat) states: "Kidney Heat disease connects to Lung, ties to tongue root, causing dry mouth/tongue and thirst." Modern physicians only claim Kidney Deficiency fails to control Heart-Fire, resulting in Upper Excess-Heat and Lower Deficiency-Cold, using Heat to tonify Kidney-Water to overcome Heart-Fire. This misunderstands Yin/Yang Excess/Deficiency. Kidney-Water belongs to Yin and is originally Cold; deficiency leads to Heat. Heart-Fire belongs to Yang and is originally Hot; deficiency leads to Cold. If Kidney-Water is Yin-Deficient, Heart-Fire is Yang-Excessive, meaning Yang-Excess and Yin-Deficiency, clearly causing Heat above and below. Thus, *Qi Jue Lun* states: "Kidney Qi declines, Yang Qi prevails alone." *Xuan Ming Wu Qi Lun* states: "Kidney dislikes Dryness, due to dried Kidney and depleted Water." *Zang Qi Fa Shi Lun* states: "Eat pungent urgently to moisten." Cold substances belong to Yin, nourish Water, and purge Heart; Hot substances belong to Yang, nourish Fire, and deplete Water. Now, since Kidney-Water cannot overcome Heart-Fire, Heat exists above and below. How can one use Hot medicines to tonify Kidney-Water to overcome Heart-Fire? Is this not absurd?
Regarding Stomach/Large Intestine Heat Binding causing thirst: *Yin Yang Bie Lun* states: "Two Yang binding causes Xiao (Consumption)." Commentary: "Yang Binding means Stomach and Large Intestine both have Heat Binding." Intestines/Stomach storing Heat efficiently consume food/water. *Qi Jue Lun* states: "Large Intestine transfers Heat to Stomach, causing excessive eating and emaciation." *Mai Yao Jing Wei Lun* states: "Dan transforms into Xiao Zhong, causing excessive eating and emaciation."
Regarding Spleen Bi causing thirst,
the majority case is simply San Jiao dry-heat stagnation and Qi decline. How can one use drying-hot toxic drugs to assist strong Yang and attack declining Yin? This is truly committing the crime of 'tonifying Excess and purging Deficiency'! Xiao Ke often complicates into deafness, blindness, sores, tinea, acne, prickly heat, etc., all due to intestinal/stomach dry-heat stagnation preventing fluids from moistening the body; or severe Heat causing Bladder stagnation, preventing secretion, leading to erratic fluid movement and facial swelling.
Regarding Small Intestine Dan Heat causing thirst: *Ju Tong Lun* (Treatise on Pain) states: "Heat stays in Small Intestine, causing abdominal pain. Dan Heat and scorched thirst lead to hard stool inability to pass." Commentary: "Heat seeps fluids, making urine hard."
Regarding Malaria causing thirst: *Nie Lun* (Treatise on Malaria) states: "Yang Excess causes exterior Heat, Yin Deficiency causes interior Heat. Interior and exterior both Heat, causing panting and thirst, thus desiring cold drinks." However, Yang-Excess and Yin-Deficiency causing Heat disease requires cold medicines to nourish Yin and purge Yang, which is the way to purge Excess and tonify Deficiency.
Regarding Rich/Greasy/Mineral Drugs causing thirst: *Qi Bing Lun* (Treatise on Rare Diseases) asks: "One with sweet taste in mouth, what is the disease name?" Qibo replies: "This is overflow of Five Qi, named Pi Dan (Spleen Dan). Dan means Heat. Spleen Heat prevents Four Zang from receiving, so Five Qi overflow upward. Originally due to Spleen Heat, hence Pi Dan." The Classics also state: "Five Flavors enter mouth, store in Stomach, Spleen transports essence. Fluids in Spleen cause sweet taste." This originates from rich food. Such people surely eat sweet/greasy foods frequently. Grease causes internal Heat; sweetness causes central fullness. Thus Qi overflows upward, transforming into Xiao Ke. *Tong Ping Xu Shi Lun* states: "Xiao Dan, sudden collapse, hemiplegia, flaccidity, reversal Qi, belong to wealthy people, diseases of rich food." Some say Stomach Qi is the root. Spleen and Stomach are interior-exterior pairs, center of Middle Jiao, should receive warm-tonification to regulate diet. Now, Xiao Ke patients have extremely deficient Spleen/Stomach, suitable for warm-tonification. Taking cold medicines damages Spleen/Stomach, making original Qi deficient and hard to treat. This view ignores Yin/Yang/Cold/Heat/Excess/Deficiency/Tonification/Purging principles, speaking recklessly. Do they not know *Fu Zhong Lun* states: Yellow Emperor asks: "Master often says Re-Zhong and Xiao Zhong cannot take Fang Cao (Fragrant Herbs) or Shi Yao (Mineral Drugs). Mineral drugs cause Dian (Mania); Fragrant herbs cause Kuang (Rage)." Commentary: "Drinking much, urinating much is Re-Zhong; Eating much, urinating much is Xiao Zhong. Much joy is Dian; Much anger is Kuang. Fang means delicious. Shi refers to Ying Ru (Mineral preparations), heating drugs." The Classics also say: "Re-Zhong and Xiao Zhong affect wealthy people." Now forbidding rich food goes against their desires; forbidding fragrant/mineral drugs leaves the disease untreated. Wish to hear the explanation. Qibo replies: "Fragrant herbs taste good; Mineral drugs act fiercely. Their Qi is rapid, firm, and strong. Only calm-hearted people can take them." Yellow Emperor asks: "Why?" Qibo replies: "Heat Qi is fierce; Drug Qi is likewise. 'Drinking one part, urinating two parts' indicates Lung Qi exiting with Water; the Sea of Grain/Water is exhausted. Seeing Xiao Ke and immediately using Hot medicines harms many. Thus, the *Neijing* should say: 'Thirst is always like this.' Is it not clear? Yet confused people remain. When Qi extremes reverse and overcome, people err. For example, Yang Extreme resembles Yin. If one does not understand Root/Branch, mistaking similarity for truth, errors persist. Thus, seeing Lower Body Cold, knees like ice, this is Heart-Fire failing to descend, resembling Cold Water. One should add Cold medicines, administer three to five times, then Fire descends, Water rises, Cold transformation retreats. Yet the world remains deluded, discarding *I Ching* and *Suwen* like rotten wood, truly pitiable! Therefore, prescribing requires understanding Disease Root/Branch, Drug Capabilities, Qi Suitability, avoiding harm, to formulate correctly. Root/Branch: First disease is Root, subsequent is Branch, this is the beginning/end of disease. When Root/Branch transmit, save the emergency first. Also: Six Qi are Root, Three Yin/Three Yang are Branch. In disease, Zang disease is most urgent. Also: Six Qi are Root of Stomach. If Stomach Heat, Stomach is Branch, Heat is Root. Prescriber should remove Heat in Stomach, treating the Root. Thus, Six Qi consider severe as Pathogen, weak as Healthy Qi. Method: Purge severe, tonify weak, aim for balance. Nourish Healthy, remove Pathogen,"
