There are individuals who cannot speak throughout their entire lives. This is due to the obstruction of the lung orifices, where Kidney Qi fails to ascend to the throat, akin to a lock firmly sealing the aperture, preventing the free flow of respiratory Qi. If the inability to speak arises from illness, it occurs only in sudden diseases such as wind-stroke (Zhong Feng) and cold damage (Shang Han). Recently, the wife of Gu Xunxiang suffered from violent anger and food stagnation, presenting with panting, abdominal distension, and incessant vomiting and regurgitation. The physician mistakenly diagnosed it as wind pathogen and administered exterior-releasing herbs, resulting in coma, staring eyes, aphasia, and unresponsiveness to calls. She sought help from Shi Wan (Zhang Lu's pseudonym). Examination revealed a choppy and submerged pulse in all six positions, indicating that phlegm was caused by Qi closure. Ideally, one should follow the momentum and induce vomiting to open the orifices. However, fearing severe vomiting, the family was given Dao Tan Tang (Phlegm-Draining Decoction) supplemented with Chang Pu (Acori Tatarinowii Rhizoma) and Yuan Zhi (Polygalae Radix). After one dose, speech was restored. Subsequently, Bing Lang (Arecae Semen) and Tie Luo (Iron Filings) were added to the formula; after defecation, the patient recovered. A disciple asked: Since this condition requires induced vomiting, why does purgation also yield results? I replied: Treating disease requires flexibility. As long as the meridians are unblocked, the "lock" naturally opens. For instance, concentrated decoction of Chen Pi (Citri Reticulatae Pericarpium) can induce vomiting; Shen Lu (Ginseng Radicis Caulis) concentrated decoction can be灌ed to induce vomiting; Jiang Zhi (Zingiberis Recens Juice) and Zhu Li (Bambusae Succus) can also induce vomiting. In wealthy households, Ju Fang Zhi Bao Dan (Official Formula Treasure Box Pill), Niu Huang Wan (Calculus Bovis Pill), and Su He Xiang Wan (Styrax Pill) are all usable. Why insist on a specific formula?
The Classic states: "Obstruction of the Two Yangs is called Xiao (Wasting-Thirst)." (The Two Yangs refer to the Yangming channels. Hand-Yangming Large Intestine governs body fluids; in Wasting-Thirst, there is yellowing of the eyes and dry mouth, indicating fluid deficiency. Foot-Yangming Stomach governs blood; heat causes rapid digestion and hunger, with latent fire in the blood, indicating blood deficiency. "Obstruction" means insufficient fluids leading to coagulation and lack of moistening, all caused by dryness-heat.) "Dan heat develops into Xiao Zhong (Middle Wasting); Heart transfers heat to the Lung, transmitting as Ge Xiao (Diaphragm Wasting)." (Irritability and thirst above the diaphragm, drinking much and digesting quickly, lung Qi fails to transform, resulting in reduced urination.) "Heart transfers cold to the Lung, forming Fei Xiao (Lung Wasting)." (Fei Xiao presents as drinking one part and urinating two parts; it is incurable/deadly. When Minister Fire loses control, Yin Fire takes over. Although Lung Metal has exogenous heat consuming water, the True Yang of the Lower Jiao fails to hold, causing increased urination, hence death.) "Large Intestine transfers heat to the Stomach, causing excessive eating but emaciation, called Shi Yi (Food Migration/Easy Digestion)." (Shi Yi refers to food passing through quickly. Stomach heat prevents muscle formation, internal consumption of fluids leads to external emaciation. If Stomach heat transfers to Gallbladder, irritability and bitter taste occur.) "Kidney Heat Disease begins with lower back pain and soreness, bitterness and thirst with frequent drinking, and body heat. Sweet taste in the mouth indicates Pi Dan (Spleen Heat)." (Five flavors enter the mouth and store in the Stomach; the Spleen distributes their essence. Fluids remaining in the Spleen cause sweet taste. Such individuals likely consume excessive sweet, fatty foods. Fatty foods generate internal heat; sweet foods cause middle Jiao fullness. Thus, Qi overflows upward, transforming into Xiao Ke (Wasting-Thirst). Treatment uses Lan Cao (Orchid Herb) to remove stale Qi.) Patients with Re Zhong (Internal Heat) and Xiao Zhong must avoid rich foods (Gao Liang), fragrant herbs (Fang Cao), and mineral drugs (Shi Yao). Mineral drugs cause mania; fragrant herbs cause frenzy. Their qi is rapid and forceful, unsuitable for those without calm hearts. Heat lingering in the Small Intestine causes pain; Dan heat scorches and thins, making stool hard and dry, leading to painful obstruction. Pulse in Xiao Dan is excess-large (curable if chronic) or suspended-small-firm (incurable if chronic). *Jin Gui* states: "Men with Wasting-Thirst have excessive urination; drinking one dou yields one dou of urine; treat with Shen Qi Wan." Kidney stores essence for transformation. Excessive loss of essence and restless fire injure Lung Dryness, causing thirst. Water entering the Stomach lacks Lung transformation to circulate. Kidney failure to constrain leads to 1:1 output ratio. Shen Qi Wan relies on Gui Zhi (Cinnamomi Ramulus) and Fu Zi (Aconiti Lateralis Radix Praeparata) for acrid-warmth to evaporate fluids and moisten organs, not merely tonifying Kidney.
Pulse floating, difficult urination, slight fever, and Wasting-Thirst indicate need for diuresis and sweating; treat with Wu Ling San (Polyporus Powder). This addresses thirst from failing water-Qi transformation, similar to Shui Ni (Water-Reversal) where drinking leads to vomiting. Both involve water-Qi blocking fluids, so Wu Ling San disperses water, allowing fluid irrigation and stopping thirst.
For incessant thirst and desire to drink, use Wen Sha San (Clam Shell Powder). Wen Sha treats cold-water exposure causing thirst without actual dryness (exterior cold-water). Here, it treats interior heat-thirst using its salty-cold nature to clear fire and moisten dryness. It is particularly suitable for Heart transferring heat to Lung (Ge Xiao). Zhao Yangkui states: Upper Xiao features red cracks on the tongue and extreme thirst; treated with Bai Hu Jia Ren Shen Tang (White Tiger Plus Ginseng Decoction). Middle Xiao features polyphagia, emaciation, spontaneous sweating, constipation, and frequent urination; treated with Tiao Wei Cheng Qi Tang (Regulate the Stomach Order the Qi Decoction). Lower Xiao features irritability, thirst, dry earlobes, and greasy urine (Kidney Xiao); treated with Liu Wei Wan (Six-Ingredient Pill with Rehmannia). Ancient methods distinguish these clearly. My view: When Water-Fire balance and Qi-Blood nourishment exist, no Wasting-Thirst occurs. Improper regulation causes Fire-Water imbalance, fluid depletion, and Dragon-Leopard Fire flaming upward, scorching intestines and drying five viscera, leading to emaciation and fatigue. Thus, treating Wasting-Thirst prioritizes the Kidney regardless of upper/middle/lower classification, using Liu Wei, Ba Wei, or Jia Jian Ba Wei Wan to descend Heart Fire and nourish Kidney Water. Bai Hu and Cheng Qi formulas are inappropriate. Ultimately, Ming Men Fire fails to return to its source; wandering to Lung causes Upper Xiao, to Stomach causes Middle Xiao. Ba Wei Shen Qi Wan guides fire back to source, achieving Water-Fire interaction, steaming moisture to the Lung. Some ask why Di Huang Tang fails for some. Answer: Heart/Lung are proximal (small dosage); Kidney/Liver are distant (large dosage). For Lower Xiao with severe dryness/thirst, use one jin of Jia Jian Ba Wei Wan material plus one liang of Rou Gui, decocted in seven bowls, taken cold while sleeping. Prescription dosage depends on flexibility.
Some desire to drink but reject water after one or two sips, then become thirsty again. This is Middle Qi deficiency-cold with cold-water flooding upward, forcing floating fire to the throat/mouth. Upper Jiao seeks water relief, but Middle Jiao rejects water. Treat with Li Zhong Tang (Regulate the Middle Decoction) delivering Ba Wei Wan if face is red and irritable.
Yu Jiayan states: Wasting-Thirst starts mild and becomes severe, starting in Stomach and ending in Lung/Kidney. Initially like water on hot iron (evaporates); later like water on stone (passes through). Drinking one, urinating one or two indicates true Yin depletion by dry-fire, leading to imminent death. *Nei Jing* discusses but lacks treatment; *Jin Gui* has both. Compilers incorrectly inserted *Shang Lun* Jueyin chapter text, confusing later generations. *Shang Lun* heat resolves without thirst; unlike chronic mixed diseases. *Nei Jing* says treating Xiao Dan, stroke, hemiplegia, flaccidity, and reverse Qi relates to rich people's dietary issues (Middle Xiao origin). Fat but poor eat poorly; noble but thin eat moderately; fat and noble consume unlimited rich food, creating internal heat and fluid depletion. Thirst increases, Middle Xiao forms. Heat spreads upward to Lung (Upper Xiao) or downward to Kidney (Lower Xiao). Upper Xiao: Stomach heat transmits to Lung, Heart heat transfers to Lung, Metal suffers Fire punishment. High source water is forced down by heat, causing 1:2 urine ratio, exhausting essence, worse than acute diarrhea, thus fatal. Lower Xiao: Stomach heat transmits to Kidney via gate; Kidney essence depleted by minerals or sexual excess, Yang strong externally, Yin insecure internally, urine greasy, 1:2 ratio, Kidney Xiao forms. Kidney is Stomach's gate. Open gate causes edema; closed gate causes Wasting-Thirst. *Jin Gui* prescribes Shen Qi Wan for 1:1 ratio to steam essence upward. Zhang Zihe criticized this, praising He Jian's Shen Xiong Wan instead, which is biased and shallow. He Baixai refuted this. Dai Ren never treated Wasting-Thirst with purgation. Lower Xiao fire is fire in water; purging intensifies it. Middle Xiao fire is fire in drained pond; purging damages it. Upper Xiao fire is prairie fire; extinguished by rain, not gut attack. Earth Qi rises to form clouds, Heaven Qi falls as rain. Must raise Earth Qi (steep Kidney Water) to irrigate Three Jiao. *Nei Jing*: Heart heat to Lung is Ge Xiao. Dai Ren confused this with Lung Xiao (Cold). Heart and Lung share the diaphragm; Lung is delicate, susceptible to both cold and heat. Cold binds externally, heat transmits internally; treatments differ. Kidney Xiao (Qiang Zhong/Nei Xiao) often from lust or minerals, causing deficient Yang, nocturnal emission, incontinence, dry lips, treated with Jia Jian Ba Wei Wan delivered by Sheng Mai San. *Qian Jin* notes mineral-induced heat cured by Piao Xiao (Mirabilite). *Jin Gui* Shen Qi Wan for 1:1 ratio; 1:2 is difficult. Misdiagnosing as Fire and using cold herbs kills; use Sheng Mai San. Upper Jiao heat: Qing Xin Lian Zi Yin. Ge Xiao (Heart/Diaphragm heat): Xuan Ming Mai Men Dong Yin Zi. Elderly thirst: Yi Lao Men Dong Yin. Middle Xiao (polyphagia/emaciation): Lan Xiang Yin Zi. Severe heat/thirst/pulse large-slippery: Gan Lu Yin Zi. Stomach heat/bad breath: Xie Huang San. Post-meal hunger/Stomach heat/Yangming pulse strong: Qi Wei Bai Zhu San. Heart/Diaphragm heat/dry mouth: Sheng Liao Gu Ben Wan plus Huang Qi, Gan Cao, Shi Hu, Ze Xie, Pi Pa Ye. Floating pulse/difficult urination/Wu Ling San indicated. If heat/thirst persists, add Ren Shen. Sweet-smelling urine indicates Spleen Qi sinking; Qi Wei Bai Zhu San. Greasy urine indicates Kidney deficiency; Bai Zhu San/Shen Qi Wan save 10-20%. Pi Xiao (Spleen Wasting) digests food instantly like snow in soup, exiting as white curds in urine, wasting muscles. Hot herbs worsen; cold herbs weaken. Sun Simiao warns of carbuncles in Wasting-Thirst patients.
[Diagnosis] Shi Wan: *Nei Jing* says excess-large pulse in Xiao Dan is curable even if chronic; suspended-small-firm pulse is incurable. Excess-large matches syndrome. Suspended-small-firm reveals True Visceral pulse, untreatable. If pulse is small but not suspended/firm, follow *Jin Gui* Shen Qi Wan. All Xiao Dan pulses show rapidity. Check floating/sinking, left/right, cun/chixia, excess/deficiency, and regional climate/person constitution to avoid errors. Northern patients often have deep-stone-slippery-rapid pulses due to cold water authority and coal heating, thick Kidney Qi; Liu/Zhang cold-purging methods work. Some laborers/water-workers have deficient Yang/unsealed storage (Right Chixi rapid-large, Lower Xiao) or exhausted Yin/dry Lung (Cunkou rapid-excess, Upper Xiao). Sexual excess/rich diet causes Slippery pulse at Qikou (Middle Xiao). Do not limit by region; guide fire, strengthen water, remove stale Qi. Southern patients (South of Yangtze) rarely have deep-stone pulses; slippery-rapid pulses feel soft upon pressure, often string-like at Chixi or large-rapid at Qikou/Mingmen due to weak soil/water and easy Kidney Yin depletion. Follow *Jin Gui*, Dong Yuan, Yangkui; Liu/Zhang methods are unsuitable. South of Yuling: floating-large-rapid pulses, apparent excess but actual deficiency. Use acrid-cool to clear heat, sweet-cold to nourish Yin; avoid acrid-hot or bitter-cold. Assess cun/chixi excess/deficiency: Cun excess indicates Qi disease; Chi deficiency indicates Kidney deficiency. Left stringy indicates essence injury; Right vigorous indicates deficient Yang. Pathogens originate internally; exterior signs are rare. Even *Jin Gui* Wu Ling San case involves water-Qi failure, not original Wasting-Thirst pulse. Floating pulse here is from exogenous pathogen, not the syndrome's root.
Shi Wan treated Scholar Zhao Xuefang: Middle Xiao, polyphagia, night meals, drowsiness after eating, acid/sweet belching, dream emissions, irregular drinking. Previously treated with calming/nourishing/clearing herbs failed. Pulse all positions large-slippery-rapid, especially Right Guan, with weak Shen at Chixi.
