Scholar Xu treated a fellow townsman, Mr. Qiu. He suffered from Shanghan (Cold Damage) with fever, headache, mental restlessness, and thirst. Although his pulse was floating and rapid, it was forceless; the chi (cun kou) position below was slow and weak. Scholar Xu said:
Although this presents as a Mahuang Tang syndrome (Taiyang exterior excess pattern), the chi pulse being slow and weak indicates that Zhang Zhongjing stated: "A chi pulse that is slow signifies insufficiency of Ying Qi (Nutritive Qi)." Sweating therapy should not be used. Instead, he employed Jianzhong Tang (Middle-Builder Decoction) added with Danggui (Angelicae Sinensis Radix) and Huangqi (Astragali Radix).
The next day, the pulse remained unchanged. The patient's family demanded sweating medicine, their words becoming almost disrespectful. Scholar Xu endured this and only used Jianzhong Tang to harmonize Ying and Wei (Nutritive and Defensive Qi). By the fifth day, the chi pulse finally responded strongly.
He then administered Mahuang Tang (Ephedra Decoction) for two doses. The patient became manic for a moment, then settled slightly and slept, after which sweat appeared. Indeed, a physician must examine the exterior and interior, deficiency and excess, and wait for the appropriate time.
If one does not follow the proper sequence but seeks temporary efficacy, damaging the five zang organs and shortening life span, what is there to praise?
[Attached from *History of the Southern Dynasties*] Fan Yun, initially an official under Emperor Wu of Liang, suddenly contracted Shanghan when the Emperor was bestowed the Nine Bestowals. Fearing he could not participate in the celebration, he summoned Xu Wenbo for diagnosis. He asked: "Can I recover immediately?" Wenbo replied: "Recovering immediately is very easy, but I fear you will not rise again in two years." Fan Yun said: "If I hear the Dao in the morning, I can die content in the evening, let alone two years." Wenbo then heated the ground with fire, spread peach leaves, laid a mat, and placed Fan Yun upon it. In an instant, sweat appeared, and warm powder was applied to his body. He recovered the next day. Fan Yun was very pleased, but Wenbo said: "There is no need to rejoice. Two years later, you will indeed pass away." Taking sweat prematurely still shortens life, let alone those who disregard the exterior and interior, do not wait for the right time, and desire rapid recovery? Therefore, this case is recorded as a warning.

One person suffered from Shanghan with difficulty in bowel movements, tidal fever in the afternoon (shen hour), unconscious grasping at empty air (clutching at bedclothes/air), staring fixedly, and急促 breathing. After several physicians had treated him, Scholar Xu said: "This is indeed a critical condition; nine out of ten die. Although Zhang Zhongjing described this syndrome without a specific treatment method, considering that purging and vomiting have already been performed, medication is difficult. If we attempt rescue, if the bowels open and the pulse becomes wiry, survival is possible." He then gave Xiao Chengqi Tang (Minor Order the Yang Treasury Decoction) once. The bowels moved freely, various symptoms gradually receded, and the pulse became slightly wiry. He recovered in half a month. Someone asked: "Why does a wiry pulse after purging indicate survival?" Scholar Xu said: "Zhang Zhongjing said: 'Clutching at clothes, terrified and uneasy, slight panting, and fixed staring; a wiry pulse indicates survival, a choppy pulse indicates death.' For mild cases with only fever and delirium, Chengqi Tang is the primary treatment. I observe in Qian Yi's *Xiao'er Yao Zheng Zhi Jue* that 'hand clutching at clothing collar and picking at objects' indicates Liver Heat. This syndrome is listed in the Yangming section by Zhang Zhongjing. Yangming refers to the Stomach. Liver heat overflowing into the Stomach meridian is why Chengqi Tang is used to purge it. Furthermore, obtaining a wiry pulse means the Liver is pacified and the Stomach is not over-controlled. Hence, there is a rationale for survival."
[Attached] Lou Quanshan said: "I once treated several people who clutched at clothes and recovered, using large tonics for Qi and Blood. Only one person also had tremors and a intermittent pulse (Dai Mai). I added two fen of Guizhi (Cinnamon Twig) to the tonic, and the tremors stopped and the pulse harmonized, leading to recovery."

One person suffered from Shanghan, initially vomiting, then shortly after being purged by a physician. It had been eight or nine days, yet there was internal and external fever. Scholar Xu diagnosed: "Baitu Jia Renshen Tang (White Tiger Plus Ginseng Decoction) should be used." Someone said: "After both vomiting and purging, the deficiency should be severe. Can Baitu Tang be used?" Scholar Xu said: "Zhang Zhongjing said: 'After vomiting and purging, if unresolved after seven or eight days, with heat consolidated internally and both exterior and interior presenting heat, use Baitu Jia Renshen Tang.' The initial vomiting indicated heat in the stomach epigastrium. Now, with a flooding and slippery pulse, great thirst desiring water, dry tongue, and irritability, only Renshen Baitu Tang will suffice."

One person suffered from Shanghan with mental restlessness, frequent vomiting, and alternating chills and fever. A physician gave Xiaochaihu Tang (Minor Bupleurum Decoction), but the illness did not resolve. Scholar Xu said: "The pulse is flooding and solid, with heat consolidated internally. How can Xiaochaihu Tang remove it? Zhang Zhongjing said: 'In Shanghan for more than ten days, with heat consolidated internally and alternating chills and fever, administer Dachaihu Tang (Major Bupleurum Decoction).' After three doses, the illness resolved."

One person presented with Taiyang syndrome. Due to excessive sweating, he experienced aversion to wind, frequent urination, and spasmodic cramping of the legs, unable to extend them. The pulse was floating and large. Scholar Xu said: "This syndrome appears in two entries in Zhang Zhongjing's formulas, largely similar with minor differences. One is: Taiyang disease, after sweating, leakage of sweat continues, aversion to wind, difficult urination, slight stiffness of the four limbs, difficult flexion and extension. The other is: Shanghan with floating pulse, spontaneous sweating, frequent urination, mental restlessness, slight aversion to cold, and leg spasms. One belongs to leakage of wind and difficult urination; the other to spontaneous sweating and frequent urination. They cannot be treated indiscriminately. This case requires Guizhi Jia Fuzi Tang (Cinnamon Twig Plus Aconite Decoction). After three administrations, sweating stopped. Assisted by Shaoyao Gancao Tang (Peony and Licorice Decoction), the legs could extend."

A boatman suffered from Shanghan with jaundice, nasal soreness, body and eyes yellow like gold, red and frequent urination, but normal stools. Someone wanted to use Yinchen Wuling San (Artemisia Capillaris Five-Ling Powder). Scholar Xu said: "This is not the correct treatment. With harmonious urination and normal stools, we know the disease is not in the zang-fu organs. Now, eye pain and nasal soreness indicate the disease is in the clear pathways. Using Dahuang (Rhubarb) to purge would certainly cause abdominal distension and adverse effects. Use Gouti San (Melon Spore Powder). First, hold water in the mouth, then insufflate into the nose. When yellow fluid flows completely from the nose, he will recover."

A military officer was captured by bandits and confined on a boat plank. After escaping days later, he ate greedily due to hunger. Later, while undressing to catch lice, he contracted Shanghan the next day. He had spontaneous sweating and diaphragmatic obstruction. One physician treated it as food stagnation and purged him; another treated it as pathogenic invasion from undressing and induced sweating. Mixed treatments for several days led to increasing confusion and drowsiness, high-pitched wheezing. Scholar Xu diagnosed: "Taiyang disease after purging, with unresolving exterior and slight panting, requires Guizhi Houpo Xingren Tang (Cinnamon Twig, Magnolia Bark, and Apricot Seed Decoction). This is Zhang Zhongjing's method." He ordered the physician to prepare this medicine. After one dose, panting stabilized; after two doses, heat eased and slight sweat appeared. By evening, the body was cool and the pulse harmonized. The physician said: "In my life, I have never used Zhang Zhongjing's formulas; I did not know..."

A woman suffered from Re Ru Xue Shi (Heat Entering the Blood Chamber). The physician did not recognize it and used blood-tonifying and qi-regulating herbs, delaying for several days until it became Xue Jie Xiong (Blood Accumulation in the Chest). Someone advised using Xiaochaihu Tang. Scholar Xu said: "Xiaochaihu Tang is now too late; it cannot be used. Only puncturing the Qimen acupoint will work. I cannot perform acupuncture; please ask a skilled practitioner to treat her." She recovered as instructed. Someone asked: "Why does Heat Entering the Blood Chamber form Chest Accumulation?" Scholar Xu said: "Pathogenic factors enter the collaterals and contend with healthy Qi, flowing up and down. Meeting menstruation that has just started or stopped, pathogens enter the Blood Chamber due to deficiency. Blood is forced by pathogens upward into the Liver meridian. The Liver receiving pathogens causes delirium and hallucinations. Returning to the Danzhong (Chest Center), blood accumulates in the chest. Why say this? In women, blood resides in the Liver. Before pregnancy, it flows downward as menstruation; during pregnancy, it is retained internally to nourish the fetus; after childbirth, it rises upward to become milk. All this is blood. Now, pathogenic factors accumulate blood, returning to the Liver meridian, gathering at Danzhong, and knotting below the breasts. Thus, touching it causes pain. Medicine cannot reach here, so puncturing Qimen is necessary."

Yu Zhen notes: Zhang Zhongjing's *Shanghan Lun* is like the Confucian classics *Da Xue* and *Zhong Yong*. The language is ancient and profound, the principles and methods deep. From the Jin dynasty to now, only Scholar Xu Shuwei has skillfully utilized this book. The dozens of medical cases preserved all offer insights and serve as models for later learners. Regrettably limited by volume, they cannot be fully recorded. Leaving these few cases allows us to glimpse the whole.

Xiang Yanzhang treated one person suffering from fever, aversion to wind, spontaneous sweating, and faint, discontinuous Qi. Physicians treated it as Shanghan, using exterior-releasing methods to reduce fever, but the condition worsened. Xiang diagnosed the pulse as deeply submerged and fine-yin, slightly rapid in both yin and yang positions. He administered Buzhong Yiqi Tang (Middle-Boosting Qi-Enhancing Decoction). The physician said: "With exterior pathogens, using Renshen (Ginseng) and Huangqi to tonify will cause pathogens to strengthen with the tonification, leading to certain death from this medicine." Xiang said: "A submerged pulse indicates interior disease. Slight rapidity indicates internal stirring of the Five Elements' fire. Discontinuous Qi indicates deficiency of Middle Qi. This is named Neishang (Internal Injury). The *Classic* says: 'For exhaustion, warm it; for deficiency, benefit it.' Drinking the previous medicine proved effective."

Yu Zhen notes: *Mingyi Leian* has a section on Internal Injury, and this case is included therein. However, observing carefully, the syndromes described in various cases resemble Shanghan closely. Whether the disease is Shanghan or Internal Injury depends solely on the physician's ability to distinguish. It is not a separate condition. Li Dongyuan's differentiation of External and Internal Injury is hardly reliable. These cases rely on pulse differentiation. Generally, Internal Injury pulses are deficient, large, and forceless, or slightly rapid and forceless. The medications are primarily Buzhong Yiqi Tang with sweet-warm properties. Wind-cold additions include exterior-releasing herbs; stagnation additions include digestion-promoting herbs; fire additions include one or two cooling herbs. There is nothing else magical. Therefore, I have selected several cases to compile into the Shanghan, Warmth, and Summerheat sections, removing Internal Injury to avoid confusion. Exterior contraction of wind-cold damages the form, hence called Shanghan. Overwork and dietary irregularities damage Qi, hence called Internal Injury. This describes the origin of disease. Once manifested, both present with fever, headache, aversion to wind/cold, and even fullness, delirium, and madness. How can one rely merely on the narrated etiology? Only when the physician sees clearly can they distinguish: "That is Shanghan, this is Internal Injury." Just as within the Shanghan category, there are deficiencies and excesses, heat and cold, with complex threads requiring careful discrimination. Thus, categorizing them separately is less fruitful than compiling and comparing them.

Li Dongyuan treated Ge Junrui, a clerk of the Western Terrace. In mid-spring, he contracted Shanghan with fever. A physician administered Baitu Tang (White Tiger Decoction). The patient's face turned black as ink, and the original symptoms disappeared. The pulse was submerged and fine, with urinary incontinence. Li Dongyuan initially did not understand. Upon diagnosis, he said: "This is due to the mistaken use of Baitu Tang before Lixia (Start of Summer). Baitu Tang is extremely cold and not a meridian-traveling medicine. Misuse causes the original Shanghan pathology to hide曲折ly within the meridians. Using extremely hot medicines to dispel yin pathogens would likely cause other syndromes to arise; this does not rescue the effects of Baitu Tang. One should use warming medicines that raise Yang and travel through meridians." A skeptic asked: "If mistakenly used with extreme cold, how can extreme heat rescue it?" Li said: "The original pathology hides in the meridians. If Yang does not rise, meridians do not flow. When meridians flow, the original symptoms appear." It healed exactly as he predicted.

Yu Zhen notes: Li Dongyuan's "warming medicines that raise Yang" were likely Cinnamon Twig, Dried Ginger, Asarum, Ligusticum, Notopterygium, Saposhnikovia, Bupleurum, and Cimicifuga. Mistakenly using cold medicines without urgent rescue with hot medicines, this is one method.

The nephew of Hanlin Academician Feng, Yue, aged sixteen, suffered from Shanghan with red eyes, mental restlessness, and thirst. The pulse was seven or eight beats per breath. A physician wanted to purge with Chengqi Tang. Li Dongyuan diagnosed: "Although the pulse is seven or eight beats, pressing it reveals no drumming force. The *Neijing* states: 'Pulse arrives following the condition, but pressing reveals no drumming; this applies to all Yang conditions.' This is Yin excess repelling Yang to the exterior, not heat. He administered Ginger and Aconite preparations, and recovery followed sweating."
[Attached] Liu Zongnong said: "This is similar to Wang Haicang's treatment of delirium with macules, fever, and submerged-fine pulse, classified as Yin Syndrome. Li Dongyuan also treated weakness of legs and knees, coldness of buttocks and hips, foul-smelling genital sweat, and seminal emission with a submerged-rapid-forceful pulse, identifying it as Fire郁 (Stagnant) internally forcing Yin outward, named Yang Excess Rejecting Yin, treated with bitter-cold purgatives. This illustrates the subtlety of Water-Fire signs and the excellence of pulse-syndrome-treatment examples."

Wang Haicang treated Hou Fu. The pulse was extremely submerged and fine, with internal cold and external heat. Macules appeared on shoulders, back, chest, and ribs, numbering over ten. Speech was chaotic and manic. Someone said: "Macules and delirium are not heat?" Wang said: "No. Yang is forced by Yin, rising to the Lung, transmitting to skin and hair, thus macules appear. Spirit fails to reside in its house, thus confused speech resembling mania, not true delirium. Although skin surface is hot, pressing with hand for a moment reveals cold penetrating like ice. He administered over twenty taels of Ginger and Aconite, resulting in profuse sweating and recovery. Later, it relapsed with a submerged-slow pulse and constipation for three to four days. He administered Lizhong Wan (Regulate the Middle Pill). Consuming about half a jin within three days, the illness completely resolved. Hou Gong's mania was not Yang mania, but loss of spirit mania, i.e., Yin syndrome."
[Attached] *Zhunsheng* records one person. After seven or eight days of Shanghan, taking cooling medicines excessively caused body temperature to drop, cold extremities, black macules over the whole body except warmth at the heart. Six pulses were submerged and fine, coma, unconsciousness, inability to speak, resembling corpse-like syncope. Ren Shen San Bai Tang (Ginseng Three Whites Decoction) plus half a prepared Fuzi (Aconite Root) and two qian of Ganjiang (Dried Ginger) were administered. After about an hour, macule color gradually reddened, extremities warmed, and consciousness returned. However, some black macules are due to lingering residual heat, which should be regulated with Huanglian Jiedu Tang (Coptis Detoxification Decoction) and Zhuye Shigao Tang (Bamboo Leaf and Gypsum Decoction) for recovery.

Luo Qianfu treated Chang Defu, Counselor of the Southern Province. In March of Ji Xu year, traveling to Dadu, he contracted Shanghan. Luo treated him. Both hands' pulses were submerged and rapid, yet externally the body was cool, extremities cold, faint purple macules visible on skin, lips and gums cracked and colorless, dry throat, hoarse voice, silent desire to sleep, eyes unable to close, restless turning, constipation. This syndrome is "Heat deep, Cold deep," transforming into Huhe (Chancroid/Ulcerative syndrome). It is most urgent. Asking attendants, he learned: "From initial cold to now, sweating medicines were taken, causing excessive sweating, gradually leading to this state." Luo said: "Usually consuming rich foods, accumulating heat internally, drying fluids. Combined with excessive sweating, fluids are doubly exhausted. Thus transferring to Yangming, causing difficult defecation." Urgently purged with Da Chengqi Tang (Major Order the Yang Treasury Decoction). After defecation, Huanglian Jiedu Tang was used, reducing illness by half. Then Huanglian Xijiao Tang (Coptis and Rhinoceros Horn Decoction) was given, recovering in several days.
[Attached] *Zhunsheng* records a woman with Huhe, hoarseness, hypersomnia, eyes unable to close, aversion to food odor, unconsciousness. Half a month later, limb rigidity, rapid and fine pulse. First administered one cup of Bamboo Juice and Ginger Juice. Suddenly, sweat appeared in the chest, borborygmus occurred, eyes closed, and consciousness returned. Then Renshen, Baizhu, Danggui, and Chenpi were added to Bamboo and Ginger Juice drink. After five or six doses, she recovered.

Yu Zhen notes: Both are Huhe syndromes, yet different in deficiency and excess. So recording both for reference.

Qu Gong, Constitutional Commissioner of Eastern Zhejiang, fell ill. Cangzhou Weng, Lu Yuanying, was summoned. Observing complexion and pulse, Lu saw Yang Qi on the face, and cunkou pulses long and wiry. It was likely a combined disease of the three Yang channels of Shanghan. Having just crossed the sea, startled by wind and waves, blood became congested and spirit frightened. Blood contended with heat, causing hematemesis of about one sheng. Also胁 pain, restlessness, thirst, and delirium. Coinciding with the annual运气 (climate cycle), the left chi should not respond. His accompanying capital physician cried and told relatives: "The monitor's pulse and illness are contrary; death is imminent." Family was panicked. Lu said: "This is Tianhe Pulse (Natural Harmony Pulse), no worry." He administered Xiaochaihu Tang, reducing Renshen dosage and adding Shengdihuang (Rehmannia Root). Waiting for stomach solidity, he purged with Chengqi Tang, leading to recovery.

Yu Zhen notes: Scholar Xu considered slow-weak chi pulse as Ying Qi insufficiency; Lu Cangzhou considered non-responsive left chi as Tianhe Pulse. Both meanings are recorded in ancient books, not new discoveries of the two gentlemen, but citations were appropriate, each achieving efficacy. This is due to familiar diagnostic skills and agile thinking.

Son of Zhao family suffered from Shanghan for over ten days, fever but quiet demeanor, six pulses completely submerged. Folk doctors thought him dead and gave no medicine. Lu Yuanying diagnosed: No pulse felt in lifting or pressing in three positions. Tongue coating slippery, malar flush red like fire, speech coherent. He told them: "This boy will surely develop extensive red macules, body like brocade. Pulse is the wave of blood. Now blood is contended by heat pathogens, becoming macules, appearing externally on skin. Breath is formless, like water in ditches; though windy, it cannot form waves. When macules disappear, pulse will emerge." Uncovering him revealed bright red macules. Immediately, Baitu Jia Renshen Tang was used to transform macules, pulse then returned to normal. Subsequently, Chengqi Tang was administered for purging, leading to recovery. Macules without pulse was not discussed by Changsha [Zhang Zhongjing]; Yuanying likely inferred this.

Quan Benran suffered from Shanghan for ten days, pathogens entering Yangming. Folk doctors, seeing fluids exiting, deficient pulse, and spontaneous sweating, administered Zhenwu Tang to tonify. This led to coma resembling deep sleep. Family invited Yuanying to ask about death date. Pulses were submerged and unseen, skin hot burning fingers. Told family: "This is likely Ying heat causing macules and submerged pulse, not comparable to Yang disease showing Yin pulse. Seeing macules should correspond to prognosis; otherwise, it is Blood Accumulation." Inspecting hidden areas and lower abdomen, red macules were indeed seen, hardness like stone below navel, painful and rejecting pressure. Huaban Tang (Transform Macules Decoction) was administered. Half a dose, macules faded, pulse emerged. Then Han Shi Shengdihuang Tang (Han's Rehmannia Root Decoction) was used to expel blood. That night, black blood was passed. Three days later, abdominal pain recurred. TaoRen Chengqi Tang (Apricot Seed Chengqi Decoction) was used to purge. Passage was as before, then recovery.

Yu Zhen reviewed these two cases and knew that macules and blood accumulation have a sign of submerged pulse. However, pondering privately, submerged pulse before macules emergence might be logical. But once macules are transparent, why must pulse recovery wait until macules transform? Wu Youke proposed "Pulse Jue" (Extinction), where slight purging with Chengqi Tang makes pulse emerge, similar to using Baitu Tang here. But macules with submerged pulse is formidable. The first case's brilliance lies in coherent speech; the second, though comatose like sleep, was due to mistaken Zhenwu Tang, so both were treated based on confirmed evidence. Lu saying "seeing macules corresponds to prognosis" and thinking of blood accumulation was already forced.

Macule manifestations vary greatly. Attaching a few more cases for review.

Huai Baoqi from Yunjian treated a woman. In summer, drinking fiery wine, she had mental restlessness, red face, and macules. Pulse was absent. Huai said: "This is Fire stagnation with extreme heat." Used Zhichi Tang (Gardenia and Fermented Soybean Decoction) added with Gegen (Kudzu Root), Houpo (Magnolia Bark), and Huanglian (Coptis) to clear. Macules erupted extensively, and pulse appeared. Largely similar to this case. Another person had Shanghan passing stages unresolved, black macules all over, dry scorched lips and mouth, constipated stool. Sanhuang Shigao Tang (Three Yellows and Gypsum Decoction) cured him. This can be viewed together with the black macule case in *Zhunsheng*. Another woman, after Heat Entering Blood Chamber, developed macules; recovered with Xiaochaihu Tang added with Shengdihuang and Mudanpi. Another person with fever and macules had gastric stagnation, unbearable distension. Using Zhike, Houpo, and digestion-promoting herbs resulted in macule eruption and heat reduction. Thus believing Zhu Fengyi's saying: "Whenever macules appear, do not treat macules exclusively. Must examine pulse floating/sinking, disease deficiency/excess, and medicate accordingly." Truly profound words. Recalling brother Ye Ningqu from Xiaogang, Louxian, years ago, with fever and incomplete macule eruption, many doctors used macule-elevating medicines without effect. I saw him spitting saliva incessantly, soft limbs unable to move, large forceless pulse, fitting the Internal Injury Macule example. Buzhong Yiqi Tang cured him. Late friend Zhang Su'an, elder brother Zunhu, had fever, cold feet, swollen eyes, loose stools, incomplete macules. Pulse submerged, fine, forceless, fitting Yin Syndrome Macule example. Zhenwu Tang added with Renshen cured him. This effectively follows Haicang and *Zhunsheng* methods. However, tongue not dry, spirit not confused, so warm tonification can be used. If summer-autumn epidemic diseases, many have macules emerging after purging with Dahuang and Huanglian. Because internal pathogen obstruction, getting unblocked leads to macule emergence, same principle as deficiency-cold getting warm tonification to encourage macule emergence. Also, in my life, I saw two people with blue macules. One, fine pulse, confused spirit, refused treatment; large blue macules like chess pieces, rotted and died. One woman with blue macules, color like kingfisher feathers, hemoptysis, epistaxis, red tongue not dry, spirit not confused, could still walk to toilet. Xijiao Dihuang Tang (Rhino Horn and Rehmannia Decoction) was used, occasionally slight purging with Dahuang. Eventually recovered. Also, Gong Yunlin treated one person. In summer, due to fatigue, irregular diet, and injury from cold drinks, illness ensued. Treated as seasonal disease without success. By tenth day, suffering heavy body, cold extremities, spontaneous diarrhea with undigested food, pulling clothes to cover, difficult breathing, lazy to speak. This is Spleen affected by Cold-Damp, insufficient Middle Qi disease. Mouth dry, wanting water but not swallowing. Morning body cool with gooseflesh, afternoon irritability, unwilling to remove clothes, drowsy with red face, faint red macules on skin. This is exterior excess, interior deficiency. Thus interior deficiency causes exterior symptoms to change with time. Used Qian Shi Baizhu San (Qian's Atractylodes Macrocephala Powder) added with Shengma (Cimicifuga), combined with Gan Ge (Kudzu) and Gancao (Licorice) from this formula to resolve macules. Added small amounts of Baizhu and Fuling to drain dampness and promote urination. Renshen, Huoxiang, and Muxiang to calm Spleen and Stomach. Advance diet. Two doses, macules retreated, body warmed, diarrhea stopped. Next dose...
