有发热之初，偶感风寒，饮食停滞而腹痛者，用加味升消平胃散一剂，其痛立止。然停
食作腹痛与毒瓦斯作腹痛，其症不同。停食腹痛者，其痛必急疾而叫啼必甚，多在脐之上，而
面必清白、唇淡、手足冷，升消平胃散主之。毒瓦斯作腹痛者，痛稍延缓，而有作有止，多在
脐下，或连腰而痛，面红而唇紫，手足不冷，败毒和中散主之。
一发热之初，有呕吐，有泄泻，有吐泻交作者，全要辨虚实寒热而用药。或吐泻交作而
胸腹痛甚者，此感寒而停食也。仍用升消平胃散主之，一服立效。或胃气弱而有寒，呕吐不
思饮食，或食下即吐，其吐必顺快而无声，面必青白，唇必淡，精神必倦怠。宜用加味参砂
和胃散主之。或脾气弱，饮食不化而泄泻，其泄必滑利而色带白。宜用术芩调脾散主之。或
有毒瓦斯作吐泻者，其吐必酸辣而有声，神气不甚困倦，其泻必黄色而秽臭，虽或吐泻交作，
胸腹多不痛。此则毒瓦斯由吐泻而发泄，所谓吐泻为顺候而不必止者，惟此一症耳。若虚寒吐
泻，与此迥异者多矣。张洁古等乃谓痘前一概吐泻，慎勿乱治而多吉，并不分虚实寒热，何
其孟浪之甚耶？
身热至二三日，痘欲出不出，或烦闷惊搐，或狂言妄语，切不可惊惶失措，须详审虚实
寒热而治之。要之此等症，皆由毒瓦斯在内，不得宣发于外。然毒瓦斯不得宣发，症有不同，不
可不辨。
有毒瓦斯壅盛于内，不得骤发于外，而惊搐狂躁，其症痘影必红紫，面赤唇紫，声音亮，
口气粗，手足热，脉洪数。此毒瓦斯壅盛也，宜用清解散宣之。
有内毒本盛，而外为风寒所束，郁滞不得出，而惊搐狂躁者。其形色多同前，但声重鼻
塞，或鼻涕，脉浮数。此毒瓦斯为风寒所束，然此多在寒凉之月，或不禁风寒者，然后有之，
宜以苏解散发之。
有气血虚弱，送毒不出，而惊搐狂躁者，其痘影淡淡在皮下，不见红舌，唇淡面白或青
，脉又迟缓，虽烦躁惊狂谵语，亦是气血虚而送毒不出也。宜用温中益气托之。
以上三者，最宜精详，观形察色，审音问症，又参之以脉，然后可以辨别明白，而用药
当，一剂之后，痘出而惊狂定矣。昔人谓痘未出之前，惊搐为顺，皆不必治，岂其然乎？
又，儿欲出痘，有发热二三日，全无痘点形影，而忽然惊搐狂躁，状与急惊风相似者，
此亦毒瓦斯壅盛，不能宣发所致。宜用清解散宣之，痘出而惊即定矣。若医者不知是痘，而误
作急惊风施治，或以寒凉药投之，或以驱痰药下之，其儿必死。何者？阻遏其毒，使不得出
而内攻也。故未出痘之儿，若遇此等症，即当惊疑，恐是出痘。
又有发热稍轻，三、四日而痘常隐隐不出者，最要详审，不可概认为毒轻痘少。若发热
和缓，精神清爽，饮食如常，出痘少而点数明，颗粒尖，渐渐长大红活，此谓毒轻痘少无
疑矣。若身热加轻，至三、四日而倦怠嗜卧，不思饮食，所出之痘，形影淡白，点粒不明，
此非毒轻痘少，亦是气血虚弱，送毒不出也。急用温中益气汤以托之，甚者必连二、三剂，
痘始出齐，其痘必多。若因其安静而袖手玩视，不急托痘出外，延至五、六日后，毒瓦斯内攻
，须臾告变，甚可畏也。则昔人热轻痘少之说，可尽信乎？而六日以前，痘未出齐，勿用温
补之说，可尽拘尽？自有方书以来，其时不啻二千年，其人不啻数百家，然皆详于已出之后
，略于未出之先，深言出速稠密之危，不言留中不出之祸。不知已出之毒外寇也，未出之毒
内寇也。内寇与外寇势孰急？内攻与外攻祸孰烈？故痘已出而死者，多在旬日之内，外痘未
出
安
而
实热者，宣发其壅滞以逐毒出外；虚寒者，补助其气血以逐毒出外。至于急用寒凉遏毒内攻
等弊，则谆谆致戒，不惮再三，一以救前哲之失，一以开后人之迷，虽岐黄复起，不易吾言
矣。
一发热至三四日报痘，形如粟米，口、鼻、腮、耳、年寿之间，先发数点，淡红润泽者
，最吉。若身热一二日即出，先发于天庭、司空、印堂等处者，或一齐涌出而稠密者，或干
枯而紫黑者，或成片不分颗粒者，皆血气凝滞而毒瓦斯肆行，最为可忧。急宜活血养气而解毒
，宜用调元化毒汤为主。腹痛者去参、 ，加枳壳八分。大便久秘者参、 不用，加熟军一
钱五分。若血气与毒瓦斯俱旺，而脉洪数者，归、芍减三分之一，去参、 不用。
若痘出不快者，其症不同，最宜分别。有痘色红紫、干枯，或密如蚕种，或一片不分颗
粒，身热，大便秘而出不快者，此毒瓦斯壅滞，血气不行也。宜用调元化毒汤，去参、 ，加
小川芎清之。
或有痘色淡白，饮食减少，身凉，手足冷，小便清，大便滑而出不快者，此气血怯弱，
不能载毒出外也。宜用温中益气汤以托之。
有鼻塞声重，咳嗽恶寒而出不快者，风寒闭之也。宜加减参苏饮以发散之，但不可出汗。
或有因邪秽所触，伏陷而出不快者，其痘必痒，宜平和汤解之。外用苍术、红枣、沉檀
烧之，以避其气。
痘正出时，有忽传风眼直视，牙关紧者，此调护不谨而外为风寒所袭也。且勿轻用驱风
峻药，宜用姜附汤。白附子二钱，此药毒重不可轻用，以制附片或肉桂代之可也，老姜二钱
，煎浓温服，出微汁自愈。
痘正出时，以身微温，不热不寒者为佳，或轻热和缓者亦无妨，惟大热者可忧；若出齐
而发大热尤可忧。其痘必稠密，必红紫，必干枯。宜用调元化毒汤去参、 主之。看痘出齐
与否，以足心为验，足心有痘则出齐矣。若痘稀者，不以此拘。
肉食不可太早，必待痘出齐而身热尽退，方可食猪肉。若身热未退，而遽食肉以助火邪
，必成大害。鸡肉首尾俱不可食，惟起胀时，虚弱者可食以助行浆。壮盛者仍宜忌之，诸鱼
皆腥，牛羊皆膻，痘家最忌，所宜禁绝。
在发热的初期，如果偶然感受风寒，加上饮食停滞导致腹痛，服用加味升消平胃散一剂，疼痛立刻停止。然而，因停食引起的腹痛与因毒瓦斯（痘毒）引起的腹痛，症状是不同的。停食引起的腹痛，疼痛必定急骤剧烈，哭闹声很大，疼痛部位多在肚脐上方，面色清白、嘴唇淡白、手脚冰凉，用升消平胃散主治。因毒瓦斯引起的腹痛，疼痛稍微迟缓，时有时无，多在肚脐下方，或者牵连腰部疼痛，面色红、嘴唇紫，手脚不凉，用败毒和中散主治。
在发热初期，有的出现呕吐，有的出现泄泻，有的吐泻同时发作，全都要辨别虚实寒热来用药。如果是吐泻同时发作且胸腹疼痛剧烈的，这是感寒兼有停食。仍然用升消平胃散主治，服一次立即见效。如果是胃气虚弱且有寒邪，呕吐不想吃东西，或者吃下去就吐，呕吐时声音顺畅没有声响，面色青白，嘴唇淡白，精神疲倦乏力，宜用加味参砂和胃散主治。如果是脾气虚弱，饮食不消化而泄泻，泄泻必定滑利且颜色带白，宜用术芩调脾散主治。如果有因毒瓦斯引起吐泻的，呕吐必定酸辣且有声响，神气不是很困倦，泄泻必定是黄色且秽臭，虽然可能吐泻同时发作，但胸腹部大多不痛。这是因为毒瓦斯通过吐泻发泄出来，所谓吐泻是顺证而不必止住的情况，只有这一种症候罢了。如果是虚寒引起的吐泻，与此大不相同了。张洁古等人却说痘疹发出前一律会有吐泻，千万不要乱治而多能获吉，并不区分虚实寒热，这也太轻率鲁莽了吧？
身体发热到二三天，痘疹想要出来却出不来，或者烦躁闷乱、惊厥抽搐，或者胡言乱语，切不可惊慌失措，必须详细审察虚实寒热来治疗。总之这类病症，都是由毒瓦斯在内，不能宣发于外所致。然而毒瓦斯不能宣发，症状有所不同，不可不辨别。
有因毒瓦斯在体内壅盛，不能骤然发于体表，而出现惊厥抽搐、狂躁不安的，其症状是痘影必定红紫，面红唇紫，声音洪亮，口气粗重，手脚发热，脉象洪数。这是毒瓦斯壅盛，宜用清解散宣发它。
有因内毒本盛，而外部被风寒束缚，郁滞不能排出，而出现惊厥抽搐、狂躁不安的。其形色大多同前一种情况，但声音沉重鼻塞，或者有鼻涕，脉象浮数。这是毒瓦斯被风寒所束，这种情况多见于寒冷的月份，或者不耐受风寒的人身上，宜用苏解散发除它。
有因气血虚弱，推动无力将毒排出，而出现惊厥抽搐、狂躁不安的，其痘影淡淡地在皮下，不见红色，嘴唇淡白、面色苍白或发青，脉象又迟缓，虽然烦躁惊狂谵语，也是气血虚弱无法将毒排出的缘故。宜用温中益气法托举毒邪外出。
以上三种情况，最需精细详察，观察形体色泽，审听声音询问症状，再结合脉象，然后才能辨别明白，用药得当，服一剂之后，痘疹发出而惊狂安定。古人说痘疹未出之前，惊搐是顺证，都不必治疗，难道真是这样吗？
另外，小儿将要出痘，有发热二三天，完全没有痘点形影，却忽然惊厥抽搐、狂躁不安，状似急惊风的，这也是毒瓦斯壅盛，不能宣发所致。宜用清解散宣发它，痘出而惊搐即定。如果医生不知道这是出痘，而误作急惊风治疗，或者投以寒凉药，或者用驱痰药攻下，患儿必定死亡。为什么呢？因为阻遏了毒邪，使其不能排出反而向内攻陷。所以未出痘的小儿，如果遇到这类症状，应当惊疑，恐怕是出痘。
又有发热稍轻，三、四天后痘疹常常隐隐不出来的，最要详细审察，不可一概认为是毒轻痘少。如果发热和缓，精神清爽，饮食如常，出痘少而点数清晰，颗粒尖挺，渐渐长大红活，这确实是毒轻痘少无疑。如果身热减轻，到了三、四天却倦怠嗜睡，不思饮食，所出的痘疹，形影淡白，点粒不明，这不是毒轻痘少，也是气血虚弱，送毒不出。急用温中益气汤托举它，严重的必须连服两、三剂，痘才出齐，其痘数量必然很多。如果因其安静而袖手旁观，不及时托痘外出，拖延到五、六日后，毒瓦斯内攻，顷刻间病情变化，非常可怕。那么古人说的“热轻痘少”的说法，可以完全相信吗？而“六日以前，痘未出齐，勿用温补”的说法，可以完全拘泥吗？自有方书以来，时间不止两千年，人数不止几百家，然而都详细论述痘已发出后的情况，略述痘未发出前的情况，深刻指出出痘迅速稠密的危险，却不提及毒留体内不出的祸患。不知道已发出的毒是外寇，未发出的毒是内寇。内寇与外寇，哪种形势紧急？内攻与外攻，哪种祸害猛烈？所以痘已发出而死的人，多在十日之内；若外痘未出而实热者，应宣发其壅滞以驱逐毒邪外出；虚寒者，补助其气血以驱逐毒邪外出。至于急用寒凉药遏阻毒邪内攻等弊端，则谆谆告诫，不厌其烦，一来挽救前贤的失误，二来启发后人的迷惑，即使岐伯、黄帝复活，也不会改变我的言论。
发热至三四天报痘，形状像粟米，口、鼻、腮、耳、年寿（鼻准）之间，先发数点，淡红润泽的，最吉利。如果身热一二天就出，先发于天庭、司空、印堂等处，或者一齐涌出而稠密的，或者干枯而紫黑的，或者成片不分颗粒的，都是血气凝滞而毒瓦斯肆行，最为可忧。急宜活血养气而解毒，宜用调元化毒汤为主。腹痛的去掉人参、[此处原文缺字，推测为某药]，加枳壳八分。大便久秘的不用人参、[此处原文缺字]，加熟大黄一钱五分。如果血气与毒瓦斯都旺盛，而脉象洪数的，当归、芍药减少三分之一，去掉人参、[此处原文缺字]不用。
如果痘出不快，症状不同，最需分别。有痘色红紫、干枯，或者密如蚕种，或者一片不分颗粒，身热，大便秘结而出痘不快的，这是毒瓦斯壅滞，血气不行。宜用调元化毒汤，去掉人参、[此处原文缺字]，加小川芎清解它。
或者有痘色淡白，饮食减少，身凉，手脚冷，小便清长，大便滑利而出痘不快的，这是气血怯弱，不能载毒外出。宜用温中益气汤托举它。
有鼻塞声重，咳嗽恶寒而出痘不快的，这是风寒闭塞所致。宜用加减参苏饮发散它，但不可令其出汗。
或者有因邪秽触碰，伏陷而出痘不快的，其痘必定瘙痒，宜用平和汤解之。外用苍术、红枣、沉水香、檀香焚烧，以避其气。
痘正出时，有忽然传变出现风眼直视、牙关紧闭的，这是调护不慎而被风寒侵袭。暂且不要轻用驱风峻烈药物，宜用姜附汤。白附子二钱，此药毒性重不可轻用，可以用制附片或肉桂代替也可，老姜二钱，煎浓温服，出微汗自愈。
痘正出时，以身体微温，不热不寒为佳，或者轻微发热和缓的也无妨，惟独大热的令人担忧；如果痘出齐了还发大热尤其令人担忧。其痘必定稠密，必定红紫，必定干枯。宜用调元化毒汤去掉人参、[此处原文缺字]主治。看痘是否出齐，以足心为验证，足心有痘则出齐了。如果痘稀少的，不以此拘泥。
肉食不可太早，必须等到痘出齐且身热尽退，方可吃猪肉。如果身热未退，就急于吃肉以助火邪，必定造成大害。鸡肉从头到尾都不可吃，惟独在起胀阶段，虚弱者可吃以助行浆。壮盛者仍宜忌口，各种鱼皆腥，牛羊皆膻，痘家最忌讳，应当禁绝。
At the initial stage of fever, if one accidentally contracts wind-cold and suffers from abdominal pain due to food stagnation, administering one dose of Jiawei Shengxiao Pingwei San (Modified Ascending, Eliminating, and Stomach-Pacifying Powder) will stop the pain immediately. However, the symptoms of abdominal pain caused by food stagnation differ from those caused by toxic vapors (smallpox toxins). Abdominal pain due to food stagnation is characterized by sudden and severe pain, loud crying, pain located mostly above the umbilicus, a clear-white complexion, pale lips, and cold hands and feet; it is treated with Shengxiao Pingwei San. Abdominal pain due to toxic vapors presents with slightly delayed pain that comes and goes, located mostly below the umbilicus or radiating to the waist, a red face with purple lips, and warm hands and feet; it is treated with Baidu Hezhong San (Toxin-Resolving and Middle-Jiao-Harmonizing Powder).
During the initial stage of fever, symptoms may include vomiting, diarrhea, or both simultaneously. Medication must be prescribed based on a differentiation of deficiency/excess and cold/heat. If vomiting and diarrhea occur together accompanied by severe chest and abdominal pain, this indicates contraction of cold combined with food stagnation. Shengxiao Pingwei San should still be used, yielding immediate results after one dose. If stomach qi is weak and cold pathogenic factors are present, leading to vomiting, loss of appetite, or immediate regurgitation after eating, where the vomit is smooth and silent, the complexion is blue-white, lips are pale, and spirit is fatigued, Jiawei Rensha Hewei San (Modified Ginseng and Amomum Stomach-Harmonizing Powder) is appropriate. If spleen qi is weak, causing indigestion and diarrhea where the stool is slippery and whitish, Shuqin Tiaopi San (Atractylodes and Scutellaria Spleen-Regulating Powder) is indicated. If vomiting and diarrhea are caused by toxic vapors, the vomit will be sour and spicy with sound, the spirit not overly exhausted, and the stool yellow and foul-smelling. Although vomiting and diarrhea may occur together, the chest and abdomen are generally not painful. This represents the venting of toxic vapors through vomiting and diarrhea, which is considered a favorable sign (shun hou) where stopping them is unnecessary; this is the only such case. In contrast, vomiting and diarrhea due to deficiency-cold are vastly different. Zhang Jiegu and others claimed that all cases prior to smallpox eruption involve vomiting and diarrhea, advising against treatment to ensure good outcomes, without distinguishing between deficiency/excess and cold/heat; this is extremely reckless.
When body heat persists for two to three days, and the rash desires to erupt but fails to do so, or if there is irritability, stifling sensation, convulsions, or delirious speech, one must not panic. Treatment requires careful examination of deficiency/excess and cold/heat. Essentially, these conditions arise because toxic vapors are trapped internally and cannot be vented externally. However, the failure of toxic vapors to vent manifests in different symptoms, necessitating differentiation.
If toxic vapors are abundant and stagnant internally, unable to suddenly erupt externally, resulting in convulsions and mania, the rash shadows will be red-purple, the face red and lips purple, voice loud, breath coarse, hands and feet hot, and pulse surging and rapid. This indicates abundant toxic vapors; Qingjie San (Clearing and Resolving Powder) should be used to vent them.
If internal toxins are originally abundant but constrained externally by wind-cold, leading to stagnation and inability to exit, resulting in convulsions and mania, the physical signs are similar to the previous case, but with heavy voice, nasal congestion, or runny nose, and a floating-rapid pulse. This indicates toxic vapors constrained by wind-cold, occurring mostly in cold months or in individuals intolerant to wind-cold. Sujiexuan San (Perilla-Resolving and Venting Powder) should be used to disperse them.
If qi and blood are weak, failing to push toxins out, resulting in convulsions and mania, the rash shadows are faint under the skin, tongue shows no redness, lips are pale, face is white or cyan, and pulse is slow and languid. Even with irritability, convulsions, madness, and delirium, this is due to qi and blood deficiency failing to expel toxins. Wenzhong Yiqi Tuo (Warming the Middle, Tonifying Qi, and Supporting/Ejecting method) is indicated.
These three categories require precise observation: examining form and color, listening to sounds, asking about symptoms, and consulting the pulse. Only then can differentiation be clear, medication accurate, and after one dose, the rash erupts and convulsions cease. Ancients claimed that convulsions before smallpox eruption are a favorable sign requiring no treatment; is this true?
Furthermore, when a child is about to develop smallpox, they may have fever for two to three days with no visible rash points, yet suddenly experience convulsions and mania resembling acute convulsive disease (Ji Jing Feng). This is also due to abundant toxic vapors unable to vent. Qingjie San should be used to vent them; once the rash erupts, convulsions cease. If physicians mistake this for acute convulsive disease and treat accordingly, using cold-cooling herbs or phlegm-dispersing purgatives, the child will surely die. Why? Because it obstructs the toxins, preventing their exit and causing internal attack. Therefore, for children before eruption encountering such symptoms, one should suspect smallpox.
In cases with slightly milder fever where the rash remains hidden for three to four days, careful examination is crucial; one must not assume light toxin and few spots. If fever is mild, spirit is clear, diet is normal, and the few erupted spots are distinct, pointed, gradually enlarging, red, and vibrant, this is indeed light toxin and few spots. However, if body heat lessens but by day three or four the child is fatigued, lethargic, anorexic, and the erupted rash is pale, indistinct, and shapeless, this is not light toxin but qi and blood deficiency failing to send toxins out. Urgently use Wenzhong Yiqi Tang (Warming Middle and Tonifying Qi Decoction) to support expulsion; severe cases may require two to three doses until the rash fully erupts, often resulting in numerous spots. If one ignores the quiet state and delays supporting the eruption, waiting until day five or six allows toxic vapors to attack internally, leading to sudden changes, which is terrifying. Thus, can the ancient saying "light heat means few spots" be fully trusted? Can the rule "do not use warming tonics before day six while the rash is incomplete" be rigidly adhered to? Since the existence of medical texts, spanning over two millennia and hundreds of authors, most detail post-eruption conditions while neglecting pre-eruption phases, warning of the dangers of rapid, dense eruptions but ignoring the disaster of retained toxins. The erupted toxin is an external invader; the un-erupted toxin is an internal invader. Which threat is more urgent? Internal attack or external attack, which is more severe? Deaths from erupted smallpox usually occur within ten days. For real-heat cases where external rash has not emerged, vent stagnation to drive toxins out; for deficiency-cold cases, tonify qi and blood to drive toxins out. Regarding the evils of urgently using cold-cooling agents to suppress toxins internally, warnings are repeated earnestly to correct past errors and enlighten future generations. Even if Qibo and Huangdi returned, my words would not change.
Reporting the rash at three to four days of fever, shaped like millet grains, appearing first in points around the mouth, nose, cheeks, ears, and nose tip (Nianshou), with a pale-red and moist appearance, is most auspicious. If the rash appears after one or two days of fever, starting at Tian Ting, Si Kong, Yin Tang, etc., or erupting densely all at once, or appearing dry, withered, purple-black, or confluent without distinct grains, this indicates blood-qii stagnation and rampant toxic vapors, which is most worrying. Urgently employ methods to invigorate blood, nourish qi, and resolve toxins, primarily using Yuanyuan Huadu Tang (Restoring Origin and Transforming Toxin Decoction). For abdominal pain, remove Ren Shen (Ginseng Root) and [missing character], add Zhi Ke (Aurantium Fruit) 8 fen. For chronic constipation, omit Ren Shen and [missing character], add Shu Jun (Prepared Rhubarb) 1 qian 5 fen. If both qi-blood and toxic vapors are vigorous with a surging-rapid pulse, reduce Gui (Angelica Sinensis Root) and Shao Yao (Peony Root) by one-third, and omit Ren Shen and [missing character].
If the rash erupts slowly, symptoms vary and must be distinguished. If the rash is red-purple, dry, dense like silkworm eggs, or confluent, accompanied by fever and constipation, this indicates toxic vapor stagnation and blocked qi-blood. Use Yuanyuan Huadu Tang, removing Ren Shen and [missing character], adding Xiao Chuan Xiong (Sichuan Lovage Rhizome) to clear.
If the rash is pale-white, with reduced diet, cool body, cold hands and feet, clear urine, and loose stools with slow eruption, this indicates deficient qi-blood unable to carry toxins out. Use Wenzhong Yiqi Tang to support expulsion.
If nasal congestion, heavy voice, cough, and aversion to cold accompany slow eruption, this is closure by wind-cold. Use Jiajian Rensu Yin (Modified Ginseng and Perilla Drink) to disperse, but avoid inducing sweating.
If triggered by foul pathogens causing latent sinking and slow eruption, the rash will itch. Use Pinghe Tang (Harmonizing Peaceful Decoction) to resolve. Externally, burn Cang Zhu (Atractylodes Rhizome), Red Dates, Chen Xiang (Aquilaria Wood), and Tan Xiang (Sandalwood) to ward off the odor.
During active eruption, sudden onset of wind-eye (staring eyes) and lockjaw indicates careless nursing and invasion by wind-cold. Do not lightly use harsh wind-dispelling drugs; use Jiang Fu Tang (Ginger and Aconite Decoction). Bai Fu Zi (Typhonii Rhizoma) 2 qian; this drug is highly toxic and should not be used lightly; processed Fu Pian (Aconite Lateralis Radix Preparata) or Rou Gui (Cinnamon Bark) may substitute. Lao Jiang (Old Ginger) 2 qian, decocted thick and taken warm; slight sweating leads to recovery.
During active eruption, a slightly warm body without heat or cold is ideal; mild, harmonious heat is also acceptable. Severe heat is worrisome; especially if high fever persists after the rash fully erupts. The rash will be dense, red-purple, and dry. Use Yuanyuan Huadu Tang, removing Ren Shen and [missing character]. To judge if the rash is complete, check the soles of the feet; presence of rash on the soles indicates completion. This rule does not apply to sparse rashes.
Meat should not be consumed too early; wait until the rash is complete and fever has completely subsided before eating pork. Eating meat while fever persists aids fire-pathogens and causes great harm. Chicken should be avoided entirely; only during the swelling phase can weak patients consume it to aid pus formation. Robust patients should avoid it. All fish are fishy, beef and mutton are gamey; these are taboo for smallpox patients and must be strictly prohibited.
