一痂后泄泻不止，目中无神而面色青者，死。一忽发大喘而类枯白唇白者死。一
痘瘢雪白者，是气血尽也。如不大补气血必死。一痂后发惊者，是心气已绝，神无所根据
不抬。一凡咽物作噎，喉中如锯，腹胀虚鸣，痰喘头汗者，死。一凡一病未已，一病
复生，五行胜复相乘者，死。
疮痂自脱痘瘢明，无凸无凹皮肉平，容貌不殊原未病，泰来否去一番新。
落痂之后瘢赤黑，爱养能教瘢自灭，突起还将风热论，四陷知因虚里得。
靥后痂皮令自脱，日久不脱脾胃弱，莫教 抽又伤肤，翻覆成疮皮似剥。
痂脱瘢痕黑暗多，劝君未可许无 ，毒邪归肾谁知得，只要其人表里和。
收靥迟迟不脱痂，神昏喜睡此无他，只因气弱神还倦，缓治求痊不必嗟。
号痂胃气未全舒，饮食安能便有余。若使食多休退喜，此中邪热未消除。
疮后新虚气未平，更宜调获保安宁，皮肤嫩薄风寒袭，肠胃伤残米谷停。
痂后身凉血气和，已知表里尽无 ，脉洪身热防余毒，解毒调荣爱益多。
夫痘密浆水清，痂后或发痈肿，人固知为余毒矣。殊不知气高而喘息作声，掀胸抬
肚者，余毒之在肺也。痰涎稠粘，咬呀戛齿，泄泻口臭者，余毒之在脾胃也。盗汗而
发热烦渴，睡中多惊者，余毒之在心也。目痛善怒，余毒之在肝也。耳 尚热，余毒之
在肾也。身肿不消，壮热不清，郁郁不乐，诸经皆有余毒也。
《痘科》云∶痘后余毒，一者疥，二者痈，三者目赤。疥者，心病也。痈者，脾病
也。目赤者，肝病也。然胎毒之发，五脏各有。一名心，心为斑，脾为疹，肺为脓泡，
肝为水泡，肾为黑陷。即发热之初，五脏俱有现症。如呵欠惊悸属心，项急顿闷属肝，
喷嚏咳嗽属肺，吐泻昏睡属脾，耳 足冷属肾。可独余毒，只言三脏，况三脏之症，又
不止于此，或者举其重而言之，欲人推展以及耳。如毒归于心，则为斑疹、为惊博、为
壮热、为丹、为诸血证。如毒归于肝，则为闷乱、为卵肿、为干呕、为诸目病、为手足
拘挛。如毒归于肺，则为咳、为喘、为衄血、为肩臂疼痛，或疮干燥皱揭。如毒归于
脾，则为口秽、为吐泻、为肿胀、为腹痛、为不食、为手足病。如毒归于肾。则为黑
陷、为多睡、为腰痛、为卒失声，甚则为败疮骨病而死。如毒归肠胃则为泄利、为便脓
血、为肠鸣失气、为大便不通。如毒归于膀胱，则为小腹满痛、为溺血、为遗尿、为头
肿痛、为目上视。惟脏腑气血未至大虚，则余毒不能内伏，治者失于清解，则毒瓦斯逗遛
经络，外不得泄于肌表，内不得入于脏腑，聚而不去，遂为之痈。甚者，头项脑胁，手
足肢节，尽皆肿痛。根浅者，易治。若根深蔓引，不独一二处者，则为溃筋伤骨而成废
疾，或绵延日久而死。至于目赤者，肝血既虚，火乘空窍也。疥癞者，血虚伏热，乃毒
之最轻者也。
夫痘顺者，其本疏，其毒微，自然易出易靥而无余毒。险者，其本密，其毒盛，自
然难出，虽靥而有余毒逆者，或陷伏，或倒靥，幸赖脾胃素强，调治又早，是以症虽得
痊而余毒未尽，因乃发而为病，多犯疥痈，目赤，痘毒，藉此消除，故凡痂落而口不
渴，身体元热，大小便调，腹中无痛，精神渐壮，饮食渐加，痂瘢红润者，此无余毒
也。若身热而渴，谵语惊搐，六脉浮洪。腹痛吐泻，或小便赤涩，大便坚秘，精神昏
愦，痂瘢赤紫，四肢倦怠，饮食减少者，此有余毒伏藏也，便须审其表里虚实，及阳虚
阴虚而加治之。然至痘疮之后，则内外俱虚，最要避寒暑，戒先澡，以养其表；节饮
食，远房室，以养其里。倘表里失调，荣卫气逆，皆可成痈成痘，岂必待因于何毒！故
毒者，偏阴偏阳，胜之所致，岂真有形恶劣
之谓欤！又不可因虚而概用温补，盖靥后原宜清解余毒，但不可太用清凉，盖气血大虚
痘痈治法，先宜审气而论虚实，察部位而加引经以治，如头加白芷、升麻、川芎∶
上身倍加桔梗；手加薄荷；腰加桂仲；腿膝加牛膝、木瓜，是其略也。若气实能食，大
便坚者，则用排毒散以疏利之，食小气虚者，则十宣散之类，以托里之。毒浅而小
者，则用小柴胡汤，加减服之，外用拔毒膏以贴之，此治肿疡之法也。若已成肿，则审
其毒之重轻，或气或血之虚弱，宜解毒而补托之，溃而成脓未破者，则用针以决去其
脓，勿使内溃。如已溃破者，则一十全大补汤主之，兼略解余毒，此治溃疡之法也。然
气血易凝滞于溥曲之所，故痘毒多发于手肘腕处，足膝 中。其在手腕者，属太阴肺，
在足 在者，属太阴脾，并宜解毒内托散主之。然痈由于痘，而痘为阳毒，故谓痘痈；
多是实毒血热，所以多用清热凉血为主，然亦有气血虚寒，元神弱者，而用凉血败毒、
必致成者不能溃，溃者不能敛矣。故贵合宜而用，药不执方也。
夫痘毒蕴于肌肤而郁热不散，则荣卫不能营运，是以结为疮疖，重则赤肿而成痈
毒，未脓宜急解表消毒，令其易散，及已成脓，则宜凉血活血，解毒托里，使其易愈。
若脓已熟者，必须以针刺去其脓，外用膏贴不刺，则害伤筋骨，不贴则毒反内攻。然凡
肿毒初起，血知痛色活，易种易脓易收者，是有元气而赤浅，吉之兆也。反此者，凶之
征也。并发于十二朝内者，多在腿脚，因痘毒之气，传注在下也。生于涌泉冲阳者，
凶。若成于足内踝太溪者，死，以毒发于肾也。若在十六朝外者，其气已升，毒随上
达，故多见于上部及头顶也，每多无事。凡痘后有遍身疮癣，如疥如癞，脓血侵淫，皮
肤溃烂，日久不愈者，此毒瓦斯弥漫于皮肤，宜升麻葛根汤类主之。若因得掐成疮者，
只以百花膏余之。更有身发红点，不肿不痛者，斑也，宜投化斑汤加玄参、地黄之类。
又有发为赤火丹瘤者，此恶候也。其毒红肿作痛。手不可近，流移上下，宜内用小柴胡
加生地黄激发，玄参化毒汤，外用砭法，去其恶血，否则，头上起者，过心即死，足上
起者，过心肾即死。
一、结痂后腹泻不止，眼中无神且面色发青的，预后不良（死）。
二、突然发生严重喘息，且嘴唇和口唇周围苍白如枯木的，预后不良（死）。
三、痘疤呈雪白色的，说明气血已经耗尽。如果不大力补益气血，必然死亡。
四、结痂后出现惊厥症状的，说明心气已经衰竭，神志无所依附而涣散。
五、凡是吞咽食物时感到噎阻，喉咙中有拉锯声，腹部胀满且虚鸣，伴有痰喘和头部出汗的，预后不良（死）。
六、凡是前一种病尚未痊愈，后一种病又生起，五行之气胜复相乘的，预后不良（死）。
疮痂自然脱落，痘疤明亮，不高凸也不凹陷，皮肉平整，容貌与患病前无异，否极泰来，焕然一新。
落痂之后若疤痕呈赤黑色，若能精心调养能使疤痕自行消退；若突起则需从风热角度论治；若下陷则知因里虚所致。
靥后痂皮应令其自然脱落，若日久不脱说明脾胃虚弱，不要让毛发牵拉又损伤皮肤，翻覆变成疮疡，皮肤似被剥落。
痂脱落后若瘢痕黑暗较多，劝你不要认为没有危险，毒邪归肾谁知道呢？只要其人表里调和即可。
收靥迟迟不脱痂，神志昏沉喜睡，这没有其他原因，只因气弱神倦，缓慢治疗以求痊愈，不必叹息。
号痂期胃气尚未完全舒展，饮食怎能便有余力？如果食欲增多不要高兴喜悦，这说明其中的邪热尚未消除。
疮后新虚，气机未平，更宜调理获得安宁，皮肤嫩薄易受风寒侵袭，肠胃伤残导致米谷停滞。
痂后身体凉爽，血气和顺，已知表里均无邪气，若脉象洪大、身体发热要防备余毒，解毒调荣益处很多。
夫痘密浆水清，结痂后或发痈肿，人们固然知道这是余毒。殊不知气息高促而喘息有声，掀胸抬肚的，是余毒在肺。痰涎稠粘，咬牙磨齿，泄泻口臭的，是余毒在脾胃。盗汗而发热烦渴，睡中多惊的，是余毒在心。目痛善怒，是余毒在肝。耳廓尚热，是余毒在肾。身体肿胀不消，壮热不清，郁郁不乐，是诸经皆有余毒。
《痘科》说：痘后余毒，一种是疥，一种是痈，一种是目赤。疥者，心病也。痈者，脾病也。目赤者，肝病也。然而胎毒之发，五脏各有表现。一名心，心表现为斑，脾表现为疹，肺表现为脓泡，肝表现为水泡，肾表现为黑陷。即在发热之初，五脏都有现症。如呵欠惊悸属心，项急顿闷属肝，喷嚏咳嗽属肺，吐泻昏睡属脾，耳冷足冷属肾。岂能独言余毒只涉及三脏，况且三脏的症状，又不止于此，或许是举出严重的来说，想让人推展了解其他情况。如毒归于心，则为斑疹、为惊痫、为壮热、为丹毒、为各种血证。如毒归于肝，则为闷乱、为睾丸肿胀、为干呕、为各种眼病、为手足拘挛。如毒归于肺，则为咳、为喘、为鼻衄、为肩臂疼痛，或疮干燥皱揭。如毒归于脾，则为口秽、为吐泻、为肿胀、为腹痛、为不食、为手足病。如毒归于肾，则为黑陷、为多睡、为腰痛、为卒然失声，甚则成为败疮骨病而死。如毒归肠胃则为泄利、为便脓血、为肠鸣失气、为大便不通。如毒归于膀胱，则为小腹满痛、为溺血、为遗尿、为头肿痛、为目上视。只有脏腑气血未至大虚，则余毒不能内伏，医者失于清解，则毒瓦斯逗留经络，外不得泄于肌表，内不得入于脏腑，聚而不散，遂形成痈。严重的，头项脑胁，手足肢节，全都肿痛。根浅的，易治。若根深蔓引，不只一两处的，则为溃筋伤骨而成废疾，或绵延日久而死。至于目赤者，肝血既虚，火乘空窍也。疥癞者，血虚伏热，乃是毒之最轻者也。
夫痘顺者，其本疏，其毒微，自然易出易靥而无余毒。险者，其本密，其毒盛，自然难出，虽靥而有余毒逆者，或陷伏，或倒靥，幸赖脾胃素强，调治又早，是以症虽得痊而余毒未尽，因乃发而为病，多犯疥痈，目赤，痘毒，藉此消除，故凡痂落而口不渴，身体元热，大小便调，腹中无痛，精神渐壮，饮食渐加，痂瘢红润者，此无余毒也。若身热而渴，谵语惊搐，六脉浮洪。腹痛吐泻，或小便赤涩，大便坚秘，精神昏愦，痂瘢赤紫，四肢倦怠，饮食减少者，此有余毒伏藏也，便须审其表里虚实，及阳虚阴虚而加治之。然至痘疮之后，则内外俱虚，最要避寒暑，戒先澡，以养其表；节饮食，远房室，以养其里。倘表里失调，荣卫气逆，皆可成痈成痘，岂必待因于何毒！故毒者，偏阴偏阳，胜之所致，岂真有形恶劣之谓欤！又不可因虚而概用温补，盖靥后原宜清解余毒，但不可太用清凉，盖气血大虚痘痈治法，先宜审气而论虚实，察部位而加引经以治，如头加白芷、升麻、川芎∶上身倍加桔梗；手加薄荷；腰加桂仲；腿膝加牛膝、木瓜，是其略也。若气实能食，大便坚者，则用排毒散以疏利之，食小气虚者，则十宣散之类，以托里之。毒浅而小者，则用小柴胡汤，加减服之，外用拔毒膏以贴之，此治肿疡之法也。若已成肿，则审其毒之重轻，或气或血之虚弱，宜解毒而补托之，溃而成脓未破者，则用针以决去其脓，勿使内溃。如已溃破者，则一十全大补汤主之，兼略解余毒，此治溃疡之法也。然气血易凝滞于溥曲之所，故痘毒多发于手肘腕处，足膝 中。其在手腕者，属太阴肺，在足 在者，属太阴脾，并宜解毒内托散主之。然痈由于痘，而痘为阳毒，故谓痘痈；多是实毒血热，所以多用清热凉血为主，然亦有气血虚寒，元神弱者，而用凉血败毒、必致成者不能溃，溃者不能敛矣。故贵合宜而用，药不执方也。
夫痘毒蕴于肌肤而郁热不散，则荣卫不能营运，是以结为疮疖，重则赤肿而成痈毒，未脓宜急解表消毒，令其易散，及已成脓，则宜凉血活血，解毒托里，使其易愈。若脓已熟者，必须以针刺去其脓，外用膏贴不刺，则害伤筋骨，不贴则毒反内攻。然凡肿毒初起，血知痛色活，易种易脓易收者，是有元气而赤浅，吉之兆也。反此者，凶之征也。并发于十二朝内者，多在腿脚，因痘毒之气，传注在下也。生于涌泉冲阳者，凶。若成于足内踝太溪者，死，以毒发于肾也。若在十六朝外者，其气已升，毒随上达，故多见于上部及头顶也，每多无事。凡痘后有遍身疮癣，如疥如癞，脓血侵淫，皮肤溃烂，日久不愈者，此毒瓦斯弥漫于皮肤，宜升麻葛根汤类主之。若因得掐成疮者，只以百花膏余之。更有身发红点，不肿不痛者，斑也，宜投化斑汤加玄参、地黄之类。又有发为赤火丹瘤者，此恶候也。其毒红肿作痛。手不可近，流移上下，宜内用小柴胡加生地黄激发，玄参化毒汤，外用砭法，去其恶血，否则，头上起者，过心即死，足上起者，过心肾即死。
One: Diarrhea that does not stop after the scabs fall off, with spiritless eyes and a bluish complexion, indicates a fatal prognosis.
Two: Sudden onset of severe panting accompanied by lips and perioral area as white as withered wood indicates a fatal prognosis.
Three: Scars that are snow-white indicate exhaustion of Qi and Blood. Without vigorous tonification of Qi and Blood, death is inevitable.
Four: Convulsions occurring after the scabs fall off indicate exhaustion of Heart Qi, where the Spirit has no foundation and dissipates.
Five: Any case where swallowing food causes choking, a sawing sound in the throat, abdominal distension with empty rumbling, phlegm-panting, and sweating on the head indicates a fatal prognosis.
Six: Any case where one disease has not yet resolved before another arises, with the Five Elements engaging in mutual overcoming and multiplication, indicates a fatal prognosis.
When sores and scabs naturally detach and the acne scars are bright, neither protruding nor depressed, with skin and flesh smooth, and the appearance unchanged from before illness, adversity turns to prosperity, bringing a new beginning.
If after shedding scabs the scars are red or black, careful nurturing can allow them to fade; if they protrude, it should be discussed in terms of Wind-Heat; if they sink inward, it is known to result from interior deficiency.
After the pockmarks heal, scabs should naturally detach; if they remain for a long time, it indicates weak Spleen and Stomach. Do not let hair pull and damage the skin, turning over into sores with skin resembling peeled layers.
If there are many dark scars after scab detachment, do not assume there is no danger; who knows if toxic pathogens have returned to the Kidney? As long as the person's exterior and interior are harmonious, it is acceptable.
Delayed shedding of scabs during the healing phase, with drowsiness and preference for sleep, has no other cause; it is merely due to weak Qi and tired Spirit. Treat slowly to seek recovery; there is no need to sigh.
During the scabbing stage, Stomach Qi has not fully relaxed; how can diet provide surplus energy? If appetite increases, do not rejoice, as this indicates the pathogenic heat within has not been eliminated.
After sores, the body is newly deficient and Qi mechanism is unbalanced; further regulation is needed to ensure peace. Delicate skin is easily attacked by Wind-Cold; damaged intestines and stomach lead to stagnation of grains.
After scabs fall, the body is cool, and Blood and Qi are harmonious, indicating no pathogens in the exterior or interior. However, if the pulse is surging and the body is hot, guard against residual toxins; resolving toxins and regulating Ying (Nutritive) Qi brings great benefit.
Regarding dense pocks with clear pus water, if carbuncles or swellings appear after scabbing, people naturally know this is residual toxin. However, one must not ignore that high-pitched breathing with audible panting, chest heaving, and belly lifting indicates residual toxin in the Lung. Thick and sticky phlegm-saliva, teeth grinding, diarrhea, and foul breath indicate residual toxin in the Spleen and Stomach. Night sweats with fever, vexation, thirst, and frequent startles during sleep indicate residual toxin in the Heart. Eye pain and irritability indicate residual toxin in the Liver. Heat remaining in the ear helix indicates residual toxin in the Kidney. Body swelling that does not subside, persistent high fever, and depression indicate residual toxin in all meridians.
The *Dou Ke* (Pockmark Science) states: Residual toxins after smallpox manifest as three types: scabies, carbuncles, and red eyes. Scabies corresponds to Heart pathology. Carbuncles correspond to Spleen pathology. Red eyes correspond to Liver pathology. However, the eruption of fetal toxins varies among the five Zang organs. The Heart manifests as macules, the Spleen as papules, the Lung as pustules, the Liver as vesicles, and the Kidney as black inversions. Even at the initial stage of fever, each Zang organ presents symptoms. For example, yawning and palpitations belong to the Heart; neck stiffness and sudden oppression belong to the Liver; sneezing and coughing belong to the Lung; vomiting, diarrhea, and lethargy belong to the Spleen; cold ears and feet belong to the Kidney. How can one claim residual toxins only involve three organs? Moreover, the symptoms of these three organs are not limited to these. Perhaps the severe cases are cited to encourage deduction of others. If toxins return to the Heart, they manifest as macules/papules, convulsions, high fever, erysipelas, and various blood disorders. If toxins return to the Liver, they manifest as confusion, testicular swelling, dry retching, various eye diseases, and limb spasms. If toxins return to the Lung, they manifest as cough, panting, epistaxis, shoulder/arm pain, or dry, wrinkled, peeling sores. If toxins return to the Spleen, they manifest as foul mouth, vomiting/diarrhea, swelling, abdominal pain, anorexia, and limb diseases. If toxins return to the Kidney, they manifest as black inversion, excessive sleep, lower back pain, sudden loss of voice, and eventually fatal bone diseases from decayed sores. If toxins return to the Intestines and Stomach, they manifest as diarrhea, bloody/purulent stools, borborygmus, and constipation. If toxins return to the Bladder, they manifest as lower abdominal fullness/pain, hematuria, enuresis, head swelling/pain, and upward-gazing eyes. Only when Zang-Fu Qi and Blood are not severely deficient can residual toxins fail to lodge internally. If physicians fail to clear and resolve, toxic vapors linger in the collaterals, unable to vent externally through the skin or enter internally into the Zang-Fu, gathering and persisting to form carbuncles. Severe cases involve swelling and pain in the head, neck, brain, temples, hands, feet, and joints. Those with shallow roots are easy to treat. If roots are deep and spreading, affecting more than one or two areas, they destroy tendons and bones, causing disability, or lead to death after prolonged duration. Regarding red eyes, since Liver Blood is deficient, Fire attacks the empty orifices. Regarding scabies/leprosy-like conditions, they result from Blood deficiency with latent heat, representing the mildest form of toxin.
Smooth smallpox has a sparse base and mild toxin, naturally emerging and healing easily without residual toxins. Dangerous cases have a dense base and strong toxin, naturally difficult to emerge; even if healed, residual toxins may arise. Adverse cases involve inversions or inverted healing. Fortunately, relying on strong Spleen and Stomach constitution and early treatment, although symptoms recover, residual toxins may remain and erupt as disease, often involving scabies, carbuncles, red eyes, or smallpox toxins, which can be eliminated thereby. Thus, if after scab shedding there is no thirst, normal body temperature, regular bowel movements, no abdominal pain, strengthening spirit, increasing appetite, and red/rosy scars, there is no residual toxin. If there is fever with thirst, delirium, convulsions, floating and surging pulses throughout six positions, abdominal pain, vomiting/diarrhea, or red/astringent urine, hard/sticky stool, mental confusion, red/purple scars, limb fatigue, and reduced appetite, this indicates hidden residual toxins. One must examine the exterior/interior, excess/deficiency, Yang deficiency/Yin deficiency, and treat accordingly. However, after smallpox, both interior and exterior are deficient. It is crucial to avoid cold and heat, refrain from bathing too early to nourish the exterior; regulate diet and avoid sexual activity to nourish the interior. If exterior and interior are disharmonious, and Ying and Wei Qi rebel, carbuncles and pocks can form; why wait to ask about specific toxins! Toxins are caused by Yin-Yang imbalance and mutual overcoming; do they truly refer to有形 (formidable) malice? Furthermore, one must not indiscriminately use warming tonics due to deficiency. After healing, clearing residual toxins is appropriate, but cooling agents should not be used excessively, as Qi and Blood are greatly deficient. Treatment of smallpox carbuncles first requires assessing Qi to determine excess/deficiency, observing location and adding guiding herbs: add Angelicae Dahuricae Radix (Baizhi), Cimicifugae Rhizoma (Shengma), Ligusticum Chuanxiong Rhizoma (Chuanxiong) for the head; double the dose of Platycodonis Radix (Jiegeng) for the upper body; add Menthae Haplocalycis Herba (Bohe) for hands; add Cinnamomi Ramulus (Guizhi) for waist; add Achyranthis Bidentatae Radix (Niuxi) and Papaveris Semen (Muguwa - *Note: likely refers to Paeoniae Radix Alba or similar for legs/knees, text says Mugua*) for legs and knees. This is a general outline. If Qi is substantial and appetite good, with hard stool, use Paidu San (Detoxification Powder) to promote drainage. If intake is small and Qi deficient, use Shixuan San (Ten Acupoints Decoction) type formulas to support the interior. For shallow and minor toxins, use Xiaochaihu Tang (Minor Bupleurum Decoction) with modifications externally applied with Badu Gao (Toxin-Drawing Plaster); this is the method for treating abscesses. If swelling has formed, assess toxin severity or Qi/Blood deficiency, and resolve toxins while supporting with tonification. If ulcerated with pus but not broken, puncture with a needle to drain pus, preventing internal rupture. If already broken, primarily use Shiquan Dabu Tang (Complete Great Tonifying Decoction), slightly resolving residual toxins; this is the method for treating ulcers. However, Qi and Blood easily stagnate in flexural areas, so smallpox toxins often occur at elbows, wrists, knees, and ankles. Those at wrists belong to Taiyin Lung; those at ankles belong to Taiyin Spleen; both should be treated with Jiedu Neituo San (Resolving-Toxin Interior-Supporting Powder). Since carbuncles arise from smallpox, and smallpox is Yang toxin, it is called "Smallpox Carbuncle"; mostly solid toxins and Blood-heat, so clearing heat and cooling Blood is primary. However, in cases of Qi/Blood deficiency-cold and weak Yuan Shen, using cooling-blood detoxifying methods will inevitably cause formed lesions to fail to suppurate and suppurated lesions to fail to heal. Therefore, appropriateness is valued, and prescriptions are not rigid.
Smallpox toxin accumulating in skin and muscles with unresolved stagnant heat prevents Ying and Wei from circulating, forming boils and furuncles. Severe cases become red and swollen, forming carbuncle toxins. Before suppuration, urgently release the exterior and detoxify to facilitate dispersion. Once pus forms, cool Blood, invigorate Blood, resolve toxins, and support the interior to facilitate healing. If pus is ripe, it must be drained by needle puncture; external plasters must be applied. Without puncturing, tendons and bones are harmed; without plasters, toxins attack internally. Generally, when swelling/toxins first appear, if blood color is active and painful, easily forming, suppurating, and healing, it indicates Yuan Qi presence and superficial redness, an auspicious sign. The opposite is inauspicious. Eruptions within twelve days mostly occur on legs and feet because smallpox toxin Qi transmits downward. Eruptions at Yongquan (KI1) or Chongyang (ST42) are ominous. Eruptions at Taixi (KI3) on the medial malleolus are fatal, as toxins erupt from the Kidney. Eruptions after sixteen days indicate ascending Qi, with toxins reaching upward, thus mostly appearing on the upper body and head, usually harmless. After smallpox, if widespread skin sores/scabies like eruptions with purulent discharge, skin ulceration, and non-healing for a long time, toxic vapors permeate the skin; use Shengma Gegen Tang (Cimicifuga and Pueraria Decoction) type formulas. If caused by scratching into sores, apply Baihua Gao (Hundred Flowers Ointment). If red spots appear without swelling or pain, these are macules; administer Huaban Tang (Macule-Resolving Decoction) with added Scrophulariae Radix (Xuanshen) and Rehmanniae Radix (Dihuang). If red fire erysipelas tumors erupt, this is a malignant condition. Toxins cause red swelling and pain, intolerable to touch, migrating up and down. Internally use Xiaochaihu Tang plus Sheng Dihuang (Raw Rehmannia) to stimulate, and Xuanshen Huadu Tang (Scrophularia Toxin-Resolving Decoction). Externally use Bianfa (Stone Needle Therapy) to remove bad blood. Otherwise, if arising on the head, crossing the Heart leads to death; if arising on feet, crossing Heart and Kidney leads to death.
