After the treatment of sweating for cold damage, the pathogenic heat should have been resolved. Why does it instead present with steaming body heat and yellowing of the face and eyes? The reason for this is that the pathogenic cold-dampness has clumped together inside the exterior shell (body surface). Therefore, jaundice occurs. Here, "interior" is a general term for the inside of the body, not implying that the cold-dampness has deeply penetrated into the zang-fu organs. Since the body and face belong to the exterior shell, they are unrelated to the zang-fu organs. One should seek the cause within the cold-dampness, which refers to the three methods mentioned below.
In cold damage, if stagnant heat is retained in the interior, the body will certainly turn yellow; Ma Huang Lian Qiao Chi Xiao Dou Tang (Ephedra, Forsythia, and Red Bean Decoction) is the primary formula. When the pathogen of cold damage encounters dampness, it becomes obstructed and fails to move, causing heat to stagnate in the body and result in jaundice. Therefore, an external resolving method is used. If one rigidly adheres to the concept of "interior," how could there be logic in treating the exterior when the pathogen is in the interior?
For cold damage presenting with jaundice and fever, Zhi Zi Bai Pi Tang (Gardenia and Phellodendron Bark Decoction) is the primary formula.
The heat has already emerged to the exterior, which is naturally different from heat stagnating internally. One should clear and resolve the jaundice following the trend of the heat, preventing it from remaining between the skin and muscles. In the previous clause, because heat was stagnant in the interior, Ma Huang (Ephedra) was used to disperse it. In this clause, because fever is at the exterior, Ma Huang is not used. The reason is that in cold-dampness patterns, it is difficult to obtain heat; once heat is present, its tendency is to move outward rather than inward. This is what is meant by seeking the cause within cold-dampness; one must not rigidly adhere to fixed rules for cold damage.
After seven or eight days of cold damage, if the body is yellow like an orange peel, urination is difficult, and the abdomen is slightly full, Yin Chen Hao Tang (Artemisia Capillaris Decoction) is the primary formula. (After taking the medicine), urine should resemble the juice of soap pods with a deep red color. After one night, abdominal fullness decreases, and the yellow color exits via urination.
Bright yellow color undoubtedly indicates heat in the Three Yang channels. Urinary difficulty and slight abdominal fullness are the fundamental signs of dampness diseases; one should not therefore identify them as interior syndromes of cold damage. The use of Da Huang (Rhubarb Root and Rhizome) in the formula is to assist Yin Chen (Artemisiae Scopariae Herba) and Zhi Zi (Gardeniae Fructus) in driving out dampness and eliminating pathogens through diuresis, not for purgation. However, there are cases where both bowel and bladder movements are obstructed: some due to urinary difficulty leading to constipation. For example, in Yangming syndrome, ten days without stool but no discomfort or thirst, or in the case of Wu Ling San (Five-Ingredient Powder with Poria), is this not caused by damp-heat carrying fluids downward into the Bladder, resulting in dry and obstructed stools? Here, due to the clumping of damp-heat and urinary difficulty causing slight abdominal fullness, a small amount of Da Huang is combined with water-draining herbs to open the lower orifice, allowing both bowel and bladder movements to become unobstructed, thereby reducing the intensity of damp-heat and facilitating its separation. ○ A question arises: Since Zhang Zhongjing mentions cold-dampness, why are herbs that dispel damp-heat avoided? The answer is that initially, cold-dampness invades the exterior shell. Over time, Yang Qi gradually recovers, becoming depressed and transforming into heat. If one rigidly sticks to the character "cold," one completely misses the meaning of transforming cold into heat.
After erroneous purgation followed by sweating, chills and a faint, thin pulse occur. The reason is deficiency in both the interior and exterior.
Erroneous sweating leads to loss of Yang Qi; erroneous purgation leads to loss of Yin fluids, resulting in deficiency in both interior and exterior. Although no formula is explicitly given, the established methods of using Fu Zi (Aconiti Lateralis Radix Preparata) to restore Yang and Ren Shen (Ginseng Radix) to benefit Yin are sufficient, requiring no further elaboration.
After erroneous purgation followed by sweating, if there is restlessness during the day preventing sleep, but quietness at night, without vomiting, thirst, or exterior signs, and with a deep, faint pulse and no significant fever, Gan Jiang Zhi Gan Cao Tang (Dried Ginger and Licorice Decoction) is the primary formula.
Restlessness during the day and quietness at night indicate that the Yin aspect is unaffected while the Yang aspect is diseased. Without exterior signs but with a deep, faint pulse, the Taiyang pathogen has been exhausted by purgation. Furthermore, repeated sweating after purgation disturbs the deficient Yang; thus, Fu Zi (Aconiti Lateralis Radix Preparata) and Gan Jiang (Zingiberis Rhizoma) are used to warm and tonify Yang. Si Ni Tang (Frigid Extremities Decoction) is not used to avoid the potential retention in the stomach caused by Gan Cao (Licorice Root) in combination with other strong warming agents, or specifically to avoid the harshness of Fu Zi in this specific context of restoring middle Jiao Yang. Similarly, for spontaneous sweating, frequent urination, dry throat, restlessness, and vomiting, Gan Jiang Zhi Gan Cao Tang is used to warm the Stomach and restore Yang; Si Ni Tang is avoided to prevent the harsh descending action of Fu Zi.
If sweating fails to resolve the disease and chills appear instead, it is due to deficiency. Shao Yao Gan Cao Fu Zi Tang (Peony, Licorice, and Aconite Decoction) is the primary formula.
Chills before sweating indicate excess pathogen and exterior excess; chills after sweating indicate the pathogen has retreated and the exterior is deficient. Yang deficiency causes chills, warranting the use of Fu Zi (Aconiti Lateralis Radix Preparata) to secure Yang. However, since the disease persists after sweating, heat remains. With heat present and no other symptoms, this is Yin deficiency heat. Shao Yao (Paeoniae Radix Alba) should be used to collect Yin. This is the rescue method for Ying and Wei Yin deficiency.
If chills appear after sweating, it is deficiency; if there are no chills but only fever, it is excess. One should harmonize the Stomach Qi with Tiao Wei Cheng Qi Tang (Modulate the Stomach and Direct the Flow Decoction).
Chills indicate recent deficiency of Ying and Wei due to sweating; thus, the method is to collect Yin, secure Yang, and harmonize Ying and Wei. Absence of chills indicates that although the exterior Qi is not yet deficient, increased aversion to heat suggests dried fluids and Stomach excess. Thus, the method is to drain excess and bring about peace. The phrase "give" implies careful consideration; direct purgation should be avoided to prevent severe depletion of fluids.
In cold damage, if the physician erroneously uses purgation, leading to continuous diarrhea with undigested food and body pain, one must urgently rescue the interior. Later, if body pain persists but bowel and bladder functions are normal, one must urgently rescue the exterior. Rescue of the interior requires Si Ni Tang (Frigid Extremities Decoction); rescue of the exterior requires Gui Zhi Tang (Cinnamon Twig Decoction).
Diarrhea with undigested food indicates weak interior Yang. Body pain indicates strong exterior pathogen. The method dictates urgent rescue of the weak interior Yang. Wait until bowel and bladder functions harmonize; then, if body pain persists, it is clearly due to disharmony of Ying and Wei, requiring urgent rescue of the exterior to allow the exterior pathogen to resolve from the outside. Rescuing the interior is vastly different from attacking the interior. Attacking the interior requires resolving the exterior first. Only when interior cold-dampness is extremely severe, fearing sudden collapse of Yang Qi, is urgent interior rescue necessary. In the Jueyin chapter, diarrhea with abdominal fullness and body pain requires warming the interior first, then attacking the exterior, illustrating the same principle.
If a disease presents with fever, headache, and a surprisingly deep pulse, and if it does not improve with body pain, one must rescue the interior, preferably with Si Ni Tang (Frigid Extremities Decoction).
Fever and headache suggest Taiyang cold damage; a surprisingly deep pulse indicates inherent deficiency or post-illness weak Yang Qi. Even with a deep pulse and deficiency, if exterior signs like headache persist, exterior-resolving medicines are used. If the disease does not improve and body pain worsens, this indicates Yang deficiency and Yin excess. Si Ni Tang (Frigid Extremities Decoction) should be given to restore Yang and scatter cold; the exterior resolves without direct intervention. The Taiyang Bladder is the fu organ of the Kidney. Kidney Yang deficiency and Yin excess inevitably transmit to the fu organ. Thus, Si Ni Tang is suitable to eliminate Yin and restore Yang. If after taking Si Ni Tang, the pulse becomes floating and rapid, and headache/body pain/fever persist, this indicates the interior Qi is assisting the expulsion of pathogens outward. A small amount of Gui Zhi Tang (Cinnamon Twig Decoction) can be used to assist sweating.
These are defective syndromes caused by Cold damaging the Ying level.
Taiyang disease lasting eight or nine days, resembling malaria with fever and chills, more heat than cold, no vomiting, normal bowel and bladder function, occurring two or three times a day, with a slightly slow pulse indicates impending recovery. A faint pulse with chills indicates dual deficiency of Yin and Yang; do not sweat, purge, or vomit again. If the face appears flushed with heat, resolution is not yet achieved; inability to produce slight sweating causes itching. Gui Zhi Ma Huang Ge Ban Tang (Half-Gui Zhi Half-Ma Huang Decoction) is appropriate.
Taiyang disease lasting eight or nine days, resembling malaria with fever and chills, more heat than cold, describes the condition from onset to now. The following text discusses future changes. Observing no vomiting and normal bowel/bladder function, occurring two or three times daily, with a slightly slow pulse indicates impending recovery. This section shows harmonious exterior with no disease, and a faint pulse indicates mild pathogen retreat. Yin and Yang are balanced, pulse and signs are consistent, signaling approaching peace; recovery may occur without sweating. If the pulse is faint with chills, this is dual deficiency of Yin and Yang; do not sweat, purge, or vomit again. This section requires warming. A reddish face indicates unresolved condition; inability to sweat slightly causes itching. Gui Zhi Ma Huang Ge Ban Tang (Half-Gui Zhi Half-Ma Huang Decoction) is needed; resolution requires sweating. The first section resembles Xiao Chai Hu Tang (Minor Bupleurum Decoction) syndrome, verified by no vomiting and normal bowels/bladder. The second section, despite faint pulse and chills, suits Xiao Jian Zhong Tang (Minor Construct the Middle Decoction) plus Huang Qi (Astragali Radix) to warm the flesh and regulate opening/closing, not primarily for warming meridians. The third section, reddish face, indicates residual exterior pathogen, hence the half-half decoction, distinct from facial flushing in other contexts.
Taiyang disease with fever, chills, more heat than cold, and a weak pulse indicates "No Yang"; do not sweat again. Gui Zhi Er Yue Bi Yi Tang (Two Parts Gui Zhi, One Part Yue Bi Decoction) is appropriate.
"No Yang" generally refers to lack of Jin Ye (Body Fluids). Jin is Yang, Blood is Yin. Lack of Yang stems from Spleen/Stomach weakness, precluding further sweating. To resolve wind-cold, take two parts Gui Zhi Tang (Cinnamon Twig Decoction) to treat wind, and one part Yue Bi (which contains Shi Gao/Gypsum) to treat stagnant heat. Shi Gao's acrid-cool nature transforms Stomach stagnant heat, generating fluids and allowing Spleen Qi to ascend and distribute Stomach fluids. The transmitted text says "Yue Bi," claiming Pi (Spleen) is a maid to the younger sister-in-law; this makes the character "Yue" meaningless and disjointed. We follow the correct version from *Waitai Miyao*.
After taking Gui Zhi Tang (Cinnamon Twig Decoction), heavy sweating occurs, and the pulse is flooding and large. Give Gui Zhi Tang (Cinnamon Twig Decoction) as before. If the pattern resembles malaria, occurring twice a day, sweating will resolve it. Gui Zhi Er Ma Huang Yi Tang (Two Parts Gui Zhi, One Part Ma Huang Decoction) is appropriate.
This is a pattern of much wind and little cold. Taking Gui Zhi Tang treats wind but leaves cold; heavy sweating results in a flooding pulse, suggesting renewed wind attack. Re-administering Gui Zhi Tang tests this. If purely wind, it resolves immediately. If resembling malaria twice daily, the pathogen intends to resolve but is held by slight cold; thus, slightly treating cold allows sweating to cure. The first half of this clause resembles Bai Hu Tang (White Tiger Decoction) syndrome in Warm Diseases, lacking "severe irritability and thirst." Severe irritability/thirst indicates heat consuming water, characteristic of latent qi, not just wanting a sip. This formula differs from Ge Ban Tang mainly in dosage/proportion, showing Zhang Zhongjing's precision.
After taking Gui Zhi Tang (Cinnamon Twig Decoction) or purging, if head/neck stiffness,翕翕 (mild) fever, no sweat, epigastric fullness with slight pain, and urinary difficulty persist, Gui Zhi Qu Gui Jia Fu Ling Bai Zhu Tang (Gui Zhi Decoction minus Cinnamon Twig plus Poria and Atractylodes Macrocephala Decoction) is primary.
Treating wind while neglecting cold causes non-resolution and transformation. Exterior wind-cold remains, while interior fluid retention rises. Thus, modify Wu Ling San (Five-Ingredient Powder with Poria) to use Bai Zhu (Atractylodis Macrocephalae Rhizoma) and Fu Ling (Poria) as main treatments. Gui Zhi (Cinnamon Twig) is removed because it was previously misused. Zhang Qingzi asks why not use Chen Pi (Citri Reticulatae Pericarpium) and Ban Xia (Pinelliae Rhizoma)? This indicates fluid retention with Stomach deficiency, causing no sweat. This resembles Jie Xiong (Chest Binding) but distinguishes itself by persistent Taiyang exterior signs, focusing on翕翕 fever.
After sweating or purging, if the disease persists with irritability, Fu Ling Si Ni Tang (Poria and Frigid Extremities Decoction) is primary.
This results from erroneous sweating/purgation in Da Qing Long Tang (Major Blue Green Dragon Decoction) syndrome, worsening irritability. Erroneous sweating loses Yang/exterior deficiency; erroneous purging loses Yin/interior deficiency. Dual deficiency with unresolved pathogen causes irritability. This formula rescues it. Fan (restlessness) is Heart irritability; Zao (fidgeting) is Kidney fidgeting. Gan Jiang (Zingiberis Rhizoma) and Fu Zi (Aconiti Lateralis Radix Preparata) enter the Kidney to resolve Zao; Fu Ling (Poria) and Ren Shen (Ginseng Radix) enter the Heart to resolve Fan. Irritability without sweating vs. after sweating differs greatly. Giving Da Qing Long Tang without pulse differentiation risks Yang collapse; thus, post-sweating irritability is already an error of sweating.
After cold damage treated with vomiting or purging, if epigastric reverse fullness, Qi rushing to the chest, dizziness upon standing, and deep-tight pulse occur, and sweating causes meridian disturbance with body tremors, Fu Ling Gui Zhi Bai Zhu Gan Cao Tang (Poria, Cinnamon Twig, Atractylodes Macrocephala, and Licorice Decoction) is primary.
This results from erroneous vomiting/purgation in Xiao Qing Long Tang (Minor Blue Green Dragon Decoction) syndrome. Epigastric reverse fullness and Qi rushing to the chest result from wind-clumping with fluid, blocking the diaphragm, causing dizziness. Post-vomit/purge, pathogen enters deficiency, moving fluid. Deep-tight pulse indicates cold-pathogen binding in the middle. Sweating alone exhausts fluids, damaging meridians, causing tremors. One must clear fluid and scatter pathogen. Xiao Qing Long Tang focuses on exterior wind-cold; here, post-vomit/purge, exterior pathogen is scattered, leaving fluid pathogen. Adding Gui Zhi (Cinnamon Twig) to fluid-resolving herbs disperses fluid pathogen, allowing fluids to nourish meridians. If excessive sweating post-vomit/purge causes Yang collapse, cold extremities, irritability, palpitations, or desire to fall, this is Zhen Wu Tang (True Warrior Decoction) syndrome, not treatable by this formula.
After cold damage treated with vomiting, purging, and sweating, if empty irritability, very faint pulse, epigastric痞硬 (stuffiness/hardness), hypochondriac pain, Qi rushing to the throat, dizziness, and meridian twitching occur over eight-nine days, prolonged suffering leads to Wei (flaccidity) syndrome.
This is the previous syndrome worsening, leading to disability. Empty irritability and faint pulse indicate internal fluid loss; deep-tight pulse is absent. Epigastric stuffiness/hardness and hypochondriac pain are worse than previous epigastric reverse fullness. Qi rushing to the throat is higher than rushing to the chest. All stem from phlegm-fluid rising. Unchecked rising to head/eyes causes worsening dizziness and tremors. Yang deficiency allows Yin to gather at the high peak, increasing tremors. Upper excess and lower deficiency lead to leg flaccidity. Zhang Zhongjing addressed this early with Fu Ling Gui Zhi Bai Zhu Gan Cao Tang.
After eight-nine days of cold damage, if Wind-Dampness clumps, causing severe body pain, inability to turn, no vomiting/thirst, and floating-deficient-choppy pulse, Gui Zhi Fu Zi Tang (Cinnamon Twig and Aconite Decoction) is primary. If stool is hard and urination normal, remove Gui Zhi and add Bai Zhu (Bai Zhu Fu Zi Tang / Atractylodes Macrocephala and Aconite Decoction).
Wind-Dampness clumping in joints causes severe pain without headache/vomiting/thirst, showing dampness rarely attacks high peaks/zang-fu. No vomiting means no upper exterior pathogen; no thirst means no interior heat. Floating-deficient-choppy pulse confirms Wind-Dampness in the exterior shell. Gui Zhi (Cinnamon Twig) scatters exterior wind; Fu Zi (Aconiti Lateralis Radix Preparata) drives meridian dampness. Normal urination and hard stool indicate fluid deficiency; thus, remove acrid-dispersing Gui Zhi and add Bai Zhu (Atractylodis Macrocephalae Rhizoma) to aid fluids.
If Wind-Dampness clumps, causing joint pain, pulling pain, inability to flex/extend, severe pain on touch, sweating, shortness of breath, urinary difficulty, aversion to wind preferring clothes, or slight swelling, Gan Cao Fu Zi Tang (Licorice and Aconite Decoction) is primary.
Wind affects the upper first; Dampness affects the lower first. Clumping in meridians/joints/bones causes universal pain. Shortness of breath indicates sweating-induced Yang loss and major Yang injury. Gan Cao (Licorice Root), Fu Zi (Aconiti Lateralis Radix Preparata), Bai Zhu (Atractylodis Macrocephalae Rhizoma), and Gui Zhi (Cinnamon Twig) restore Yang and resolve interior/exterior pathogens.
In cold damage, if floating pulse, spontaneous sweating, frequent urination, heart irritability, slight chills, and foot cramping occur, and Gui Zhi Tang (Cinnamon Twig Decoction) is wrongly given to attack the exterior, this is an error. Resulting in cold extremities, dry throat, irritability, and vomiting, make Gan Cao Gan Jiang Tang (Licorice and Dried Ginger Decoction) to restore Yang. If extremities warm, make Shao Yao Gan Cao Tang (Peony and Licorice Decoction) to extend the feet. If Stomach disharmony causes delirium, give small amounts of Tiao Wei Cheng Qi Tang (Modulate the Stomach and Direct the Flow Decoction). If heavily sweated and moxa-burned, Si Ni Tang (Frigid Extremities Decoction) is primary.
This is Yang deficiency with Ying/Wei injury, wrongly treated with Gui Zhi Tang, neglecting cold and interior. Floating pulse/spontaneous sweating suggest exterior wind; frequent uritation/heart irritability suggest interior pathogen. Slight chills and foot cramping indicate severe interior cold. Using Gui Zhi Tang solely for exterior worsens Yang deficiency and Yin unconstraint, causing cold extremities. Gui Zhi Tang is wrong; Ma Huang Tang (Ephedra Decoction) and Da Qing Long Tang (Major Blue Green Dragon Decoction) are even more inappropriate. Interior Yin-cold precludes exterior attack. Gan Cao Gan Jiang Tang restores Yang, scattering cold. Once extremities warm, fear prior acrid-hot herbs damaged Yin and tightened cramps; thus, Shao Yao Gan Cao Tang harmonizes Yin to extend feet. If Stomach disharmony causes delirium, fluids are consumed by heat; small amounts of Tiao Wei Cheng Qi Tang harmonize Stomach and stop delirium. Too much constitutes purgation, not harmony. If unaware of non-sweating indication and heavily sweated/moxa-burned, Yang collapse and Yin unconstraint ensue. Si Ni Tang (Frigid Extremities Decoction) restores Yang; adding Yin-nourishing herbs is contraindicated. This syndrome involves hidden Yin deficiency. Though floating pulse/spontaneous sweating seem Yang-excess, foot cramping/coldness indicates chronic lower deficiency. Heart irritability/frequent urination show both True Yang and True Yin deficiency. Using Yang-restoring herbs led to cold extremities.
Question: Syndrome resembles Yang Dan, treated according to method but worsens with cold extremities, dry throat, calf cramping, and delirium. Master said hands/feet would warm and legs extend at midnight, which happened. How did you know? Answer: Cun Kou pulse floating and large. Floating indicates wind; Large indicates deficiency. Wind generates slight heat; deficiency causes calf cramping. Syndrome resembles Gui Zhi Tang, so Fu Zi (Aconiti Lateralis Radix Preparata) was added, and Gui Zhi (Cinnamon Twig) increased to induce sweating. Fu Zi warms meridians; Yang loss occurred. Cold extremities, dry throat, irritability, Yangming internal binding, delirious confusion. Drink Gan Jiang Gan Cao Tang again. At midnight, Yang returns, feet warm. Calves still slightly cramped; re-give Shao Yao Gan Cao Tang to extend calves. Use Cheng Qi Tang slightly to soften stool and stop delirium. Hence, recovery is known.
Yang Dan is Gui Zhi Tang plus Huang Qin (Scutellariae Radix), the correct formula for Winter-Warmth. Given wrongly due to heart irritability/frequent urination resembling Winter-Warmth. Patient's inherent weak Yang caused immediate cold extremities. Heavy sweating or moxa-burning adds error; only Si Ni Tang (Frigid Extremities Decoction) can restore Yang. Treating as Winter-Warmth method explains immediate cold extremities, clearly due to Huang Qin aiding Yin-cold. Single Gui Zhi Tang would not cause this. Thus, Zhang Zhongjing used Yin Dan method to correct error. Increasing Gui Zhi to sweat and adding Fu Zi to warm meridians ignores dry throat/Yangming delirium, prioritizing Gan Jiang Gan Cao Tang to wait for midnight Yang return. Testing confirmed prediction. Huang Qin induced cold extremities quickly; Gui/Fu/Gan Jiang followed. Recovery was certain. Delirium/dry throat mixed with heat signs rule out severe Yin-cold. Once feet warmed, focus shifted to harmonizing Yin. How prudent!
These are defective syndromes of dual Ying/Wei injury.
Taiyang Wind Strike treated with fire-induced sweating: Pathogenic wind meets fire, blood/qi overflow, losing normal rhythm. Two Yangs scorch the body, causing jaundice. Yang excess leads to nosebleed; Yin deficiency leads to difficult urination. Dual Yin/Yang exhaustion causes dry body. Only head sweats up to neck. Abdominal fullness, slight wheezing, dry mouth, rotten throat, or constipation. Long-term delirium, severe retching, hand/foot restlessness, picking at clothes/bed. If urination is free, treatable.
Wind is Yang; Fire is Yang. Pathogenic wind aided by fire boils blood/qi, losing rhythm. Steaming causes jaundice. Yang pathogen in Yang positions may resolve via nosebleed or sweat. But Yang pathogen entering Yin positions consumes all fluids. Sweat stops below neck. Dry mouth/throat, scorched lungs, wheezing, dry body, difficult urination, constipation, restlessness, delirium, retching indicate fierce fire-pathogen and imminent death of True Yin, beyond medicinal power. Treatable only if urination is free, indicating Yin not fully injured, Lung Qi not reversed, Bladder Qi transformation active, Kidney Water not dry. Then, driving Yang and saving Yin is possible. Commentators cling to "dual Yin/Yang exhaustion," thinking free urination means Yin not deficient and Yang recoverable, mistaking "treatable" for "Yang restoration." This misses the classic intent. Urgent Yang rescue preserves a thread of Yin; even this is doubtful, let alone restoring Yang to further consume Yin. Head sweat is Yang pathogen congesting upward.
