The Master said: If a patient's pulse is faint (Wei) and choppy (Se), this is due to medical error. Because of excessive sweating, followed by repeated severe purgation, the patient has lost blood. The condition should manifest as alternating aversion to cold and fever, without cessation. In the height of summer heat, the patient desires to wear thick clothes; in the depth of winter cold, the patient desires to expose the body. The reason for this is that when Yang Qi is deficient, there is aversion to cold; when Yin is weak, there is fever. Thus, excessive sweating makes Yang Qi even more deficient, and severe purgation makes Yin Qi even weaker. In the fifth month, Yang Qi floats on the exterior, while the Stomach is cold and empty. Because internal Yang Qi is deficient and cannot overcome cold, the patient desires to wear thick clothes. In the eleventh month, Yang Qi sinks into the interior, causing vexatious heat in the Stomach. Because internal Yin Qi is weak and cannot overcome heat, the patient desires to expose the body. Furthermore, a slow (Chi) and choppy (Se) pulse in the Yin positions indicates loss of blood.
After three days of Taiyang disease, if sweating, emesis, purgation, or warm needle therapy have been applied but the disease remains unresolved, this is termed a "ruined disease" (Huai Bing). Guizhi Tang (Cinnamon Twig Decoction) is no longer applicable. One must observe the pulse and symptoms, determine what therapeutic error was committed, and treat according to the current pattern. If the pulse is floating (Fu) and rapid (Shu), the method dictates recovery through sweating. However, if purgation was mistakenly used, it leads to heaviness of the body and palpitations. Sweating is contraindicated at this stage; recovery will occur naturally through spontaneous sweating. This is because a faint pulse at the Chi position indicates interior deficiency. When both exterior and interior are solidified and fluids are harmonized, spontaneous sweating will lead to cure. Generally, whether a disease has undergone sweating, emesis, purgation, or involves blood/fluid loss, if Yin and Yang can self-harmonize, the disease will surely resolve on its own.
After severe purgation followed by sweating, if the patient experiences difficulty urinating, this is due to fluid depletion. Do not forcibly treat it; when urination resumes, the patient will likely recover spontaneously. After purgation followed by sweating, chills and tremors will inevitably occur, accompanied by a faint and fine pulse. This is due to deficiency in both the interior and exterior.
If Taiyang disease is first treated with purgation without resolution, and then sweating is induced, leading to deficiency in both exterior and interior, the patient may experience dizziness (Mao). Patients with dizziness will recover through spontaneous sweating, because the exterior harmony is restored. Once the exterior is harmonized, purgation may then be considered.
If, after six or seven days of illness, the pulse is slow (Chi) and floating-weak (Fu Ruo), with aversion to wind and cold, and warm hands and feet, but the physician repeatedly uses purgation, the patient may suffer from inability to eat much, fullness in the hypochondrium, yellowing of the face and body, stiff neck, and difficult urination. Administering Chaihu Tang (Bupleurum Decoction) would subsequently cause a sensation of rectal heaviness. If the patient was originally thirsty and vomiting upon drinking water, Chaihu Tang is also contraindicated, and eating may induce hiccups.
In Taiyang disease lasting two to three days, if the patient cannot lie down and only wishes to rise, there must be obstruction in the epigastrium. If the pulse is faint, this indicates an underlying cold condition. If purgation is mistakenly used, and diarrhea stops, chest binding (Jie Xiong) will form. If diarrhea does not stop, and purgation is repeated on the fourth or fifth day, this constitutes diarrhea with attached heat.
If Taiyang disease is treated with purgation, and the pulse becomes urgent (Cu) without forming chest binding, the disease is about to resolve. If the pulse is floating, chest binding will form. If the pulse is tight (Jin), throat pain will occur. If the pulse is string-taut (Xian), bilateral hypochondriac stiffness will occur. If the pulse is fine and rapid, headache will persist. If the pulse is deep and tight, vomiting will ensue. If the pulse is deep and slippery, diarrhea with attached heat will occur. If the pulse is floating and slippery, hematochezia will occur.
In concurrent Taiyang and Shaoyang diseases, mistaken purgation leads to chest binding, hardness in the epigastrium, unceasing diarrhea, inability to swallow liquids, and mental restlessness. If a floating-tight pulse is treated with purgation, the tight pulse moves inward, resulting in epigastric fullness (Pi). It feels soft upon pressure, constituting merely Qi stagnation. After emesis, purgation, or sweating in Shanghan, if mental restlessness occurs with a very faint pulse, and after eight or nine days, epigastric hardness, hypochondriac pain, Qi rushing up to the throat, dizziness, and twitching of meridians occur, this may eventually develop into Wei syndrome (flaccidity syndrome).
In Yangming disease, if the patient cannot eat and purgation fails to resolve the condition, the patient remains unable to eat. Attacking the heat will induce hiccups because the Stomach is cold and deficient.
In Yangming disease, if the pulse is slow, and the patient cannot eat until full, experiencing vexation and dizziness after eating, and difficulty urinating, this indicates impending Gu Dan (Grass Jaundice). Even with purgation, abdominal fullness persists due to the slow pulse.
In Taiyang disease, if the Cun pulse is slow, Guan pulse floating, and Chi pulse weak, with fever, sweating, aversion to cold, no vomiting, but epigastric fullness, this is caused by mistaken purgation. After severe emesis and purgation in Shanghan, leading to extreme deficiency, followed by excessive sweating causing exterior Qi oppression, giving water to induce sweating results in hiccups due to cold in the Stomach. After emesis, purgation, and sweating, if the pulse is normal but slight irritability remains, it is because the newly deficient state cannot handle food Qi.
If Taiyang disease is treated with sweating, leading to fever and aversion to cold, followed by purgation causing epigastric fullness, this indicates deficiency in both exterior and interior, exhaustion of Yin and Yang Qi, where the absence of Yang leaves Yin alone. Adding fire needle therapy causes irritability, bluish-yellow complexion, and dry skin, making it difficult to treat. However, if the complexion is slightly yellow and hands and feet are warm, it is easy to cure. If Guizhi Tang is taken followed by purgation, resulting in stiff neck and head, mild fever, no sweating, epigastric fullness with slight pain, and difficulty urinating, this belongs to the pattern of Guizhi Qu Gui Jia Fuling Baizhu Tang (Cinnamon Twig Decoction minus Cinnamon Twig plus Poria and Atractylodes Macrocephala Decoction).
If Taiyang disease is first treated with sweating without resolution, followed by purgation, and the pulse remains floating, the disease will not resolve. Floating indicates the pathogen is external; purging externally prevents resolution. Since the pulse is floating, the pathogen is still external, and releasing the exterior with Guizhi Tang will cure it. After purgation followed by sweating, if the patient experiences daytime irritability and insomnia, nighttime quietness, no vomiting or thirst, no exterior signs, a deep-faint pulse, and no significant fever, this belongs to Ganjiang Fuzi Tang (Dried Ginger and Aconite Root Decoction). After Shanghan treated with emesis, purgation, and sweating, if there is epigastric rebellious fullness, Qi hitting the chest, dizziness upon standing, a deep-tight pulse, and body tremors upon sweating, this belongs to Fuling Guizhi Baizhu Gancao Tang (Poria, Cinnamon Twig, Atractylodes Macrocephala, and Licorice Decoction). If unresolved after sweating, emesis, and purgation, with irritability, this belongs to Fuling Sini Tang (Poria and Four Reversal Decoction). After Shanghan treated with sweating, emesis, and purgation, if mental restlessness and insomnia occur, or severe tossing and turning with inner vexation, this belongs to Zhizi Chi Tang (Gardenia and Fermented Soybean Decoction). If shortness of breath, use Zhizi Gancao Tang (Gardenia and Licorice Decoction). If vomiting, use Zhizi Shengjiang Tang (Gardenia and Fresh Ginger Decoction). If abdominal fullness, use Zhizi Houpo Tang (Gardenia and Magnolia Bark Decoction). If sweating or purgation leads to vexation, heat, and chest oppression, this belongs to the Zhizi Chi Tang pattern.
If Taiyang disease passes the meridian stage for over ten days, with epigastric nausea, chest pain, loose stools, slight abdominal fullness, and slight vexation, following previous extreme emesis or purgation, Chengqi Tang (Bowels Unblocking Decoction) may be given. Otherwise, do not give it. Vomiting, chest pain, and loose stools indicate this is not a Chaihu Tang pattern, but rather a result of extreme emesis/purgation. If Taiyang disease is heavily sweated and purged, leading to five to six days of constipation, dry tongue with thirst, slight afternoon tidal fever, and hardness/pain from epigastrium to lower abdomen, this belongs to Daxiexion Tang (Major Chest Binding Decoction). If Shanghan lasts five to six days, after sweating and purgation, with slight chest/hypochondriac fullness, difficulty urinating, thirst without vomiting, only head sweating, alternating chills/fever, and irritability, this is unresolved and belongs to Chaihu Guizhi Ganjiang Tang (Bupleurum, Cinnamon Twig, and Dried Ginger Decoction).
After Shanghan sweating, emesis, or purgation resolves, if epigastric hardness and persistent belching remain, this belongs to Xuanfuzhe Tang (Inula and Hematite Decoction). After severe purgation, Guizhi Tang is contraindicated. If sweating, wheezing, and lack of high fever occur, Mahuang Xingren Gancao Shigao Tang (Ephedra, Apricot Kernel, Licorice, and Gypsum Decoction) may be used. After severe purgation followed by sweating, if epigastric fullness and aversion to cold persist, the exterior is unresolved. Do not attack the fullness; resolve the exterior first with Guizhi Tang, then attack the fullness with Dahuang Huanglian Xiexin Tang (Rhubarb, Coptis, and Scutellaria Heart-Clearing Decoction).
After Shanghan emesis/purgation, if unresolved after seven to eight days, with heat consolidated internally, exterior-interior heat, frequent aversion to wind, extreme thirst, dry irritable tongue, and desire to drink several liters of water, this belongs to Baihu Tang (White Tiger Decoction). If unresolved after emesis/purgation, with five to ten+ days of constipation, afternoon tidal fever, no aversion to cold, and delirious speech as if seeing spirits, severe cases involve unconsciousness, grasping at clothes, fearfulness, slight panting, and fixed gaze. A string-taut pulse indicates life; a choppy pulse indicates death. Mild cases with fever and delirium belong to Chengqi Tang. If purged, do not administer again. In concurrent San Yang disease, with abdominal fullness, body heaviness, difficulty turning, oral insensitivity, facial grease, delirium, and enuresis, sweating worsens delirium; purgation causes forehead sweating and cold extremities with spontaneous sweating. This belongs to Baihu Tang.
In Yangming disease, if the pulse is floating-tight, with dry throat, bitter taste, abdominal fullness, wheezing, fever, sweating, no aversion to cold but preference for heat, and body heaviness, sweating induces agitation and delirium. Warm needles cause fear and insomnia. Purgation empties the Stomach, allowing hostile Qi to disturb the Diaphragm, causing inner vexation and tongue coating, belonging to Zhizi Chi Tang.
In Yangming disease, after purgation, if exterior heat exists, hands/feet are warm, no chest binding, inner vexation, hunger but inability to eat, and only head sweating, this belongs to Zhizi Chi Tang.
In Yangming disease, after purgation, if inner vexation and irritability occur with dry feces in the Stomach, purgation is indicated. If the abdomen is slightly full but stool is hard at the beginning and loose at the end, purgation is contraindicated. Dry feces indicate the Chengqi Tang pattern.
After Taiyang disease treated with emesis/sweating/purgation, if slight irritability, frequent urination, and hard stool occur, Xiao Chengqi Tang (Minor Bowels Unblocking Decoction) may harmonize and cure.
After massive sweating or purgation, if cold extremities occur, this belongs to Sini Tang (Four Reversal Decoction).
In Taiyang disease, after purgation, if the pulse is urgent with chest fullness, this belongs to Guizhi Qu Shaoyao Tang (Cinnamon Twig Decoction minus Peony Decoction). If slight aversion to cold occurs, add Fuzi, becoming Guizhi Qu Shaoyao Jia Fuzi Tang.
After Shanghan five to six days, severe purgation leaves fever and heart-binding pain, indicating the disease is not resolving, belonging to Zhizi Chi Tang.
After Shanghan purgation, if irritability and abdominal fullness cause restlessness, this belongs to Zhizi Houpo Tang.
If a physician uses pill-based purgatives in Shanghan, leaving fever and slight irritability, this belongs to Zhizi Ganjiang Tang (Gardenia and Dried Ginger Decoction).
If a physician purges Shanghan, leading to continuous clear grain diarrhea, and body pain exists, urgently save the interior with Sini Tang. If body pain exists but stool is normal, urgently save the exterior with Guizhi Tang.
If Taiyang disease passes the meridian stage for ten+ days, and is repeatedly purged, and after four to five days Chaihu patterns persist, start with Xiao Chaihu Tang (Minor Bupleurum Decoction). If vomiting stops and comfort returns (or vomiting continues with epigastric urgency), and vexation persists, give Da Chaihu Tang (Major Bupleurum Decoction) to purge. If Shanghan persists thirteen days with chest/hypochondriac fullness, vomiting, afternoon tidal fever, and slight diarrhea, although Chaihu purgation was indicated, the diarrhea suggests the physician used pill purgatives incorrectly. Tidal fever indicates excess. First, take Xiao Chaihu Tang to release the exterior, then use Chaihu Jia Mangxiao Tang (Bupleurum plus Mirabilite Decoction).
If Shanghan persists thirteen days, passes the meridian, with delirium indicating internal heat, purgation with decoction is needed. If urination is free, stool should be hard; if loose with a harmonious pulse, it indicates incorrect pill purgation. Spontaneous loose stool usually implies a faint/cold pulse; a harmonious pulse here indicates internal excess, belonging to Chengqi Tang.
After Shanghan eight to nine days, purgation leads to chest fullness, fright, difficulty urinating, delirium, and inability to turn the body, belonging to Chaihu Jia Longgu Muli Tang (Bupleurum plus Dragon Bone and Oyster Shell Decoction). Fire-negativity followed by purgation and fire-needle induced irritability belongs to Guizhi Gancao Longgu Muli Tang (Cinnamon Twig, Licorice, Dragon Bone, and Oyster Shell Decoction).
In Taiyang disease, a floating-moving-rapid pulse indicates Wind, Heat, Pain, and Deficiency respectively. Headache, fever, slight night sweat, and aversion to cold indicate the exterior is unresolved. Mistaken purgation changes the moving-rapid pulse to slow, causing dizziness or diaphragmatic pain. Empty Stomach allows hostile Qi to disturb the Diaphragm, causing shortness of breath, irritability, inner vexation, and sinking of Yang Qi into the epigastrium, forming chest binding (Daxiexion Tang). If no chest binding, but only head sweating stopping at the neck, with difficulty urinating, jaundice will develop.
If Shanghan five to six days presents with vomiting and fever, and Chaihu patterns are complete, mistaken purgation leaves Chaihu patterns intact. Re-administering Chaihu Tang is not adverse. The patient will shiver and sweat out the fever to resolve. If epigastric fullness is hard and painful, it is chest binding (Daxiexion Tang). If full but not painful, it is Pi (epigastric fullness), Chaihu Tang is contraindicated; use Banxia Xiexin Tang (Pinellia Heart-Clearing Decoction). If purgation caused epigastric fullness, give Xiexin Tang. If unresolved with thirst, dry mouth, and difficulty urinating, use Wuling San (Five-Ingredient Powder with Poria). Some say enduring it for one day cures it.
In Shanghan or Fengzhong, mistaken purgation causes frequent diarrhea with undigested food, borborygmus, epigastric hardness/fullness, dry retching, and vexation. Seeing epigastric fullness, the physician mistakenly purges again, worsening the fullness. This is not heat binding, but Stomach deficiency with hostile Qi reversing upward, belonging to Gancao Xiexin Tang (Licorice Heart-Clearing Decoction).
If Shanghan medication causes continuous diarrhea and epigastric hardness, and Xiexin Tang fails, subsequent purgation worsens diarrhea. Lizhong Tang treats the Middle Jiao, but this diarrhea is in the Lower Jiao; use Chishizhi Yuyuliang Tang (Red Halloysite and Illite Decoction). If unresolved, promote diuresis.
If Taiyang exterior signs persist and repeated purgation causes heat-attached diarrhea, epigastric hardness, and unresolved exterior-interior, this belongs to Guizhi Renshen Tang (Cinnamon Twig and Ginseng Decoction).
After Shanghan emesis, if abdominal fullness occurs, give Chengqi Tang. If a patient has no exterior-interior signs, fever for seven to eight days, and a floating-rapid pulse, purgation may be used. If purgation fails to resolve the rapid pulse, and heat causes hunger with digestion, followed by constipation after six to seven days, blood stasis exists, belonging to Didang Tang (Di Dang Decoction). If the rapid pulse persists with bleeding, pus and blood in stool will occur.
If Taiyang disease is mistakenly purged, causing intermittent abdominal fullness and pain, it belongs to Taiyin, treated with Guizhi Ji Shaoyao Tang (Cinnamon Twig plus Peony Decoction). Severe pain belongs to Guizhi Jia Dahuang Tang (Cinnamon Twig plus Rhubarb Decoction).
After Shanghan six to seven days, severe purgation leads to deep-slow pulse, cold extremities, absent lower pulses, sore throat, spitting pus/blood, and continuous diarrhea, making it difficult to treat; use Mahuang Shengma Tang (Ephedra and Cyathula Decoction).
If Shanghan originally involved cold purgation, and the physician re-emetics/purges, causing cold rejection and immediate vomiting upon eating, use Ganjiang Huangqin Huanglian Renshen Tang (Dried Ginger, Scutellaria, Coptis, and Ginseng Decoction).
