（此症感四时邪毒之气，其后发于鼻面耳项咽喉，赤肿无头，或结核有根，寒热头痛，状如伤
寒。此乃时行湿毒之气，发于头面，所谓大头瘟也。以其能作脓出毒，故入外科。）
少宰李蒲汀患时毒，用发散之药，耗损元气，患处不消，体倦恶寒，食少口干。用益气汤加桔梗，
及托里消毒散而愈。
秋官陈同野患时毒，元气素弱，脉微细而伏，此形病俱虚也。用参、术、芎、归、陈皮、柴胡、
升麻、炙草以升举阳气，用牛蒡、元参、连翘、桔梗以解热毒，二剂肿顿消，而脉亦复矣。苟以脉微
细为属阴，以肿赤为属阳而药之，鲜有不误者。
一妇人时毒溃后，肿赤不消，食少体倦，脓清色白，乃脾肺气虚也。先用六君加桔梗、芎、归，
后用益气汤加桔梗而敛。
春官袁谷虚之妹，患时毒，表散过度，肿硬不痛，脉浮大，按之而短，此真气绝也。辞不治，后
果殁。
一男子患此症，肿痛发热作渴，脉实便秘，以五利大黄汤下之，诸症悉退。以葛根牛蒡子汤，四
剂而痊。
一男子患此症，表里俱解，肿痛尚不退。以葛根升麻汤，二剂而肿消。
一男子患此症，肿痛发寒热，脉浮数，以荆防败毒散，二剂少愈。以人参败毒散，二剂势减半，
又二剂而痊。
一男子患此症，耳面赤肿作痛，咽干发热，脉浮数，先以荆防败毒散二剂，势退大半。以葛根牛
蒡子汤，四剂而痊。
一妇人患此症，表邪已解，肿尚不消。诊之，数脉滑而数，乃瘀血欲作脓也，以托里消毒散溃之
而愈。
一男子患此症， 肿胀痛作渴，烦热便秘，脉数按之尤实，用防风通圣散一剂，诸症顿退。以荆
防败毒散加元参、牛蒡、黄芩，二剂而瘥。
一老人冬月头、面、耳、项俱肿痛甚，便秘，脉实，此表里俱实病也。饮防风通圣散不应，遂砭
患处出黑血，仍投前药即应，又以荆防败毒散而瘳。盖前药不应者，毒血凝聚上部经络，药力难达故
也。恶血既去，其药自效。或拘用寒远寒，及年高畏用硝、黄，而用托里，与夫寻常之剂，或不砭泄
其毒，专假药力，鲜不危矣。（徐灵胎曰∶通圣散乃治表里俱热之方，所谓两解法也。须审定内外俱
热之症，乃可消息施用。又曰∶荆防败毒散为时毒主方，惟人参不宜轻用。）
一男子患此症，表里俱解，惟肿不消。以托里消毒散四剂，脓成，针之而愈。
一妇人患此症，肿痛，用硝黄之剂，攻之稍缓，翼日复痛。诊之，外邪已退，此瘀血复作脓也，
用托里消毒散溃之而愈。
一男子头面肿痛，服硝黄败毒之剂愈甚。诊之，脉浮数，邪在表尚未解，用荆防败毒散二剂，势
退大半。更以葛根牛蒡子汤，四剂而痊。《内经》曰∶身半以上肿，天之气也；身半以下肿，地之气
也。乃邪客心肺之间，上攻头目而为肿。此感四时不正之气为患，与夫膏粱积热之症不同。硝黄之剂，
非大便秘实不可用。若不审其因，不辨其虚实表里，概用攻之，必致有误。常见饥馑之际，刍荛之人，
多患之，乃是胃气有损，邪气从之为患，不可不察。常治邪在表者，用葛根牛蒡子汤、人参败毒散，
或普济消毒饮子。邪在里者，五利大黄汤、栀子仁汤。表里俱不解者，防风通圣散。表里俱解而肿不
退者，犀角升麻汤。如肿甚者，砭患处出恶血以泄其毒，或用通气散取嚏以泄其毒，十日外自愈，若
嚏出脓血即愈。欲其作脓者，用托里消毒散；欲其收敛者，用托里散，此法最为稳当。五七日咽喉肿
闭，言语不出，头面不肿，食不知味者，不治。（此乃时行湿毒之气，发于头面，所谓大头瘟也。以
其能作脓出毒，故入外科。）
一男子患此症，服表散药愈炽，发热便秘。诊其脉沉实，此邪在里也。以大黄汤下之，里症悉退。
以葛根
牛蒡子汤，浮肿亦消。惟赤肿尚存，更以托里药溃之而愈。齐氏云∶时毒者，为四时邪毒之气而感之
于人也。其后发于鼻、面、耳、项、咽喉，赤肿无头，或结核有根，令人憎寒发热，头痛。或肢体痛
甚者，恍恍不宁，咽喉闭塞，昧者将谓伤寒，便服解药，一二日肿气增益方悟，始求疡医。原夫此症，
古无方论，世俗通为丹瘤，病家恶言时毒，切恐传染。考之于经曰∶人身忽经变赤，状如涂丹，谓之
丹毒。此风热恶毒所为，与时毒特不同耳。盖时毒初起，状如伤寒，五七日间，乃能杀人，治者宜精
辨之。先诊其脉滑、数、浮、洪、沉、紧、弦、涩，皆其候。盖浮数者，邪气在表也，沉涩者，邪气
深也。气实之人，急服化毒丹以攻之；热实不利，大黄汤下之；其有表症者，解毒升麻汤以发之；或
年高气软者，五香连翘汤主之。又于鼻内 通气散，取十余嚏。左右看病之人，每日用 药嚏之，则
不传染。其病患每日亦用嚏药三五次，以泄热毒。此治时毒之良法也。经三四日不解者，不可大下，
犹宜和解之，服犀角连翘散之类。至七八日，大小便不通利，头面肿起高赤者，可服托里散、黄 散，
宜镰砭割出血，泄其毒瓦斯。十日外，不治自愈也。此病若五日以前，精神昏乱，咽喉闭塞，语声不出，
头不肿，食不知味者，必死，治之无功矣。然而此疾有阴有阳，有可汗有可下。常见粗工但云热毒，
就用寒凉，殊不知病有微甚，治有逆从，不可不审也。
徐考功年逾三十，耳面 肿，寒热拘急，脉浮洪，此时毒症也。邪在表，以荆防败毒散加牛蒡、
元参治之，渐愈。更以升麻、葛根、连翘、桔梗、川芎、银花、牛蒡而平复。
（此病证感受四时邪毒之气，随后发作于鼻、面、耳、项、咽喉部位，红肿无头，或结成硬块且有根蒂，伴有恶寒发热、头痛，症状类似伤寒。这是时行湿毒之气，发于头面部，即所谓的大头瘟。因为此病能化脓排出毒素，所以归入外科范畴。）
少宰李蒲汀患时毒，使用发散药物后，耗损了元气，患处肿胀不消，身体疲倦、怕冷，食欲减退、口干。使用益气汤加桔梗，以及托里消毒散治疗而痊愈。
秋官陈同野患时毒，素来元气虚弱，脉象微细而伏，这是形体与病气都虚弱的表现。使用人参、白术、川芎、当归、陈皮、柴胡、升麻、炙甘草来升举阳气，使用牛蒡子、玄参、连翘、桔梗来解除热毒，服用两剂后肿胀顿时消退，脉象也恢复了。如果认为脉微细属于阴证，认为肿赤属于阳证而分别用药，很少有不误诊的。
一位妇人时毒溃破后，红肿不消，饮食减少、身体疲倦，脓液清稀色白，这是脾肺气虚的表现。先用六君子汤加桔梗、川芎、当归，后用益气汤加桔梗，使伤口收敛愈合。
春官袁谷虚的妹妹，患时毒，因表散过度，导致肿块坚硬且不痛，脉象浮大，重按则短促，这是真气绝灭的表现。拒绝治疗，后来果然去世。
一名男子患此病，肿痛发热、口渴，脉象实大、便秘，用五利大黄汤攻下，各种症状全部消退。再用葛根牛蒡子汤，服用四剂后痊愈。
一名男子患此病，表里症状都已解除，但肿痛仍未消退。用葛根升麻汤，服用两剂后肿胀消退。
一名男子患此病，肿痛并伴有寒热，脉象浮数，用荆防败毒散，服用两剂后症状稍有好转。用人参败毒散，服用两剂后病情减半，又服两剂后痊愈。
一名男子患此病，耳部面部红肿疼痛，咽干发热，脉象浮数，先用荆防败毒散两剂，病情退去大半。再用葛根牛蒡子汤，服用四剂后痊愈。
一名妇人患此病，表邪已解，但肿胀仍未消退。诊察发现，脉象滑数，这是瘀血将要化脓的表现，用托里消毒散促使排脓而痊愈。
一名男子患此病，肿胀疼痛、口渴，烦热便秘，脉象数且重按尤为坚实，用防风通圣散一剂，各种症状顿时消退。再用荆防败毒散加玄参、牛蒡子、黄芩，服用两剂后病愈。
一位老人在冬季头部、面部、耳朵、颈部都严重肿痛，便秘，脉象实大，这是表里俱实的病证。饮用防风通圣散没有效果，于是用砭石刺患处放出黑血，再投以前药方立即见效，后又用荆防败毒散而治愈。之前药方无效的原因，是毒血凝聚在上部经络，药力难以到达。恶血去除后，药物自然生效。如果拘泥于“寒远寒”（寒冷季节慎用寒药）的说法，以及年老畏惧使用芒硝、大黄，而改用托里法，或者使用寻常药剂，如果不通过砭石泄毒，专门依赖药力，很少有不出危险的。（徐灵胎说：防风通圣散是治疗表里俱热的方剂，即所谓的“两解法”。必须审定内外俱热的症状，才能斟酌施用。又说：荆防败毒散是治疗时毒的主方，其中人参不宜轻易使用。）
一名男子患此病，表里症状都已解除，只有肿胀未消。用托里消毒散四剂，脓液形成，针刺排脓后痊愈。
一名妇人患此病，肿痛，使用含芒硝、大黄的药剂攻下后，疼痛稍缓，第二天又痛。诊察发现，外邪已退，这是瘀血再次化脓的表现，用托里消毒散促使排脓而痊愈。
一名男子头面部肿痛，服用含芒硝、大黄等败毒药剂后病情加重。诊察发现，脉象浮数，邪气在表尚未解除，用荆防败毒散两剂，病情退去大半。再用葛根牛蒡子汤，服用四剂后痊愈。《内经》说：身体上半部分的肿胀，是天之气所致；身体下半部分的肿胀，是地之气所致。这是邪气客居在心肺之间，向上攻冲头目而导致肿胀。这是感受四时不正之气为患，与膏粱厚味积热引起的病证不同。含芒硝、大黄的药剂，除非是大便干结实证才可使用。如果不审察病因，不辨别虚实表里，一概使用攻下法，必然会导致误治。常见于饥荒之际，底层百姓多患此病，这是因为胃气受损，邪气趁机作乱，不可不仔细考察。通常治疗邪气在表的，用葛根牛蒡子汤、人参败毒散，或普济消毒饮子。邪气在里的，用五利大黄汤、栀子仁汤。表里都不解的，用防风通圣散。表里都解了但肿胀不退的，用犀角升麻汤。如果肿胀严重的，用砭石刺患处放出恶血以泄毒，或用通气散取嚏以泄毒，十日左右自愈，如果喷嚏中排出脓血即愈。想要它化脓的，用托里消毒散；想要它收敛的，用托里散，这种方法最为稳妥。如果发病五七日后，咽喉肿胀闭塞，不能言语，头面部不肿，进食不知味道，属于不治之症。（这是时行湿毒之气，发于头面部，即所谓的大头瘟。因为此病能化脓排出毒素，所以归入外科范畴。）
一名男子患此病，服用表散药物后病情更重，发热便秘。诊察其脉象沉实，这是邪气在里。用大黄汤攻下，里证全部消退。再用葛根牛蒡子汤，浮肿也消退。只有红肿尚存，再用托里药促使排脓而痊愈。齐氏说：时毒，是人感受四时邪毒之气而得的病。随后发作于鼻、面、耳、项、咽喉，红肿无头，或结成硬块且有根蒂，令人憎寒发热、头痛。或者肢体疼痛严重的，心神恍惚不安，咽喉闭塞，庸医将其误认为伤寒，便服用解表药，一二天后肿胀气盛才醒悟，才开始求治外科医生。原来此病，古代没有方论，世俗通称为丹瘤，病人厌恶提及“时毒”，担心传染。考证经典记载：人身忽然变红，状如涂丹，称为丹毒。这是风热恶毒所致，与时毒特别不同。大概时毒初起，症状像伤寒，五七日内，可能致死，治疗者应当精细辨别。先诊察其脉象滑、数、浮、洪、沉、紧、弦、涩，都是其征候。大概脉浮数的，邪气在表；脉沉涩的，邪气深。气实的人，急服化毒丹以攻邪；热实且大便不利，用大黄汤攻下；有表证的，用解毒升麻汤发汗；或者年高气弱的人，主用五香连翘汤。又在鼻内吹入通气散，取十余个喷嚏。左右看护的病人，每天用药取嚏，则不会被传染。病患每天也用嚏药三五次，以泄热毒。这是治疗时毒的好方法。经过三四天不解的，不可峻下，仍宜和解，服用犀角连翘散之类。到了七八日，大小便不通利，头面肿起高赤的，可服用托里散、黄芪散，宜用镰刀砭割出血，泄其毒瓦斯。十日外，不治也会自愈。此病如果在五日以前，精神昏乱，咽喉闭塞，声音不出，头不肿，进食不知味道，必定死亡，治疗也无功了。然而此疾有阴证有阳证，有可发汗有可攻下。常见粗劣的医生只说是热毒，就用寒凉药，却不知道病有轻重，治有逆从，不可不审慎。
徐考功年过三十，耳面部肿胀，恶寒发热、肢体拘急，脉象浮洪，这是时毒症。邪气在表，用荆防败毒散加牛蒡子、玄参治疗，逐渐好转。再用升麻、葛根、连翘、桔梗、川芎、金银花、牛蒡子，病情平复。
(This condition is caused by contracting the pathogenic qi of epidemic toxins from the four seasons. Subsequently, it manifests on the nose, face, ears, nape, and throat, presenting with redness and swelling without a head, or forming nodules with roots. It is accompanied by aversion to cold, fever, and headache, resembling Taiyang disease (Taiyang syndrome). This is due to the damp-toxin qi of seasonal epidemics manifesting on the head and face, known as "Da Tou Wen" (Great Head Plague). Because it can suppurate and discharge toxins, it is classified under Surgery.)
Li Puting, Vice Minister, suffered from Shi Du (Seasonal Epidemic Toxin). After using diaphoretic drugs, his Yuan Qi (Primal Qi) was depleted. The affected area did not subside; he experienced fatigue, aversion to cold, poor appetite, and dry mouth. He was treated with Yiqi Tang (Qi-Supplementing Decoction) plus Jiegeng (Platycodonis Radix), and Tuoli Xiaodu San (Interior-Supporting and Toxin-Resolving Powder), resulting in recovery.
Chen Tongye, Official of Autumn, suffered from Shi Du. His Yuan Qi had been weak since childhood, and his pulse was faint, fine, and deep. This indicates deficiency in both form and disease. He was prescribed Renshen (Ginseng Radix et Rhizoma), Baizhu (Atractylodis Macrocephalae Rhizoma), Chuanxiong (Ligustici Chuanxiong Rhizoma), Danggui (Angelicae Sinensis Radix), Chenpi (Citri Reticulatae Pericarpium), Chaihu (Bupleuri Radix), Shengma (Cimicifugae Rhizoma), and Zhigancao (Prepared Glycyrrhizae Radix et Rhizoma) to raise and uplift Yang Qi. Niubangzi (Arctii Fructus), Xuanshen (Scrophulariae Radix), Lianqiao (Forsythiae Fructus), and Jiegeng were used to resolve heat toxins. After two doses, the swelling subsided instantly, and the pulse recovered. If one were to classify the faint and fine pulse as Yin syndrome and the redness and swelling as Yang syndrome, treating them separately, few would avoid error.
A woman suffered from Shi Du after ulceration. The redness and swelling did not subside; she had poor appetite and fatigue. The pus was clear and white, indicating deficiency of Spleen and Lung Qi. She was first treated with Liujunzi Tang (Six-Gentlemen Decoction) plus Jiegeng, Chuanxiong, and Danggui. Later, she was treated with Yiqi Tang plus Jiegeng, leading to wound contraction and healing.
The younger sister of Yuan Guxu, Official of Spring, suffered from Shi Du. Due to excessive use of exterior-releasing methods, the swelling became hard and painless. Her pulse was floating and large but short upon deep pressure, indicating exhaustion of True Qi. Treatment was declined, and she subsequently died.
A man suffered from this condition with swelling, pain, fever, thirst, a full pulse, and constipation. He was purged with Wuli Dahuang Tang (Five-Benefits Rhubarb Decoction), after which all symptoms receded. He was then treated with Gegen Niubangzi Tang (Kudzu and Arctopus Decoction) for four doses, resulting in recovery.
A man suffered from this condition where exterior and interior symptoms had resolved, yet swelling and pain persisted. He was treated with Gegen Shengma Tang (Kudzu and Cimicifuga Decoction) for two doses, after which the swelling subsided.
A man suffered from this condition with swelling, pain, chills, and fever. His pulse was floating and rapid. He was treated with Jingfang Baidu San (Schizonepeta and Saposhnikovia Powder to Overcome Toxicity) for two doses, showing slight improvement. He was then treated with Renshen Baidu San (Ginseng Powder to Overcome Toxicity) for two doses, reducing the severity by half. After another two doses, he recovered.
A man suffered from this condition with redness, swelling, and pain in the ears and face, dry throat, fever, and a floating, rapid pulse. He was first treated with Jingfang Baidu San for two doses, reducing the severity by more than half. He was then treated with Gegen Niubangzi Tang for four doses, resulting in recovery.
A woman suffered from this condition where exterior pathogens had resolved, but swelling persisted. Palpation revealed a slippery and rapid pulse, indicating that blood stasis was about to suppurate. She was treated with Tuoli Xiaodu San to promote suppuration and recovery.
A man suffered from this condition with swelling, pain, thirst, irritability, fever, and constipation. His pulse was rapid and particularly firm upon deep pressure. He was given Fangfeng Tongsheng San (Saposhnikovia and Gentian Powder to Unblock the Whole Body) for one dose, after which all symptoms receded instantly. He was then treated with Jingfang Baidu San plus Xuanshen, Niubangzi, and Huangqin (Scutellariae Radix) for two doses, resulting in recovery.
An elderly man suffered from severe swelling, pain, and constipation in the head, face, ears, and nape during winter. His pulse was full. This was a condition of excess in both exterior and interior. Drinking Fangfeng Tongsheng San yielded no result. Consequently, Bian stones (stone lancets) were used to puncture the affected area to release dark blood. Upon resuming the previous medication, it took effect immediately. He was further treated with Jingfang Baidu San and healed. The reason the previous medication failed was that toxic blood was condensed in the upper meridians, preventing the medicinal power from reaching the site. Once the evil blood was removed, the medicine naturally worked. If one adheres strictly to the principle of avoiding cold medicines in cold seasons ("Han Yuan Han") or fears using Mangxiao (Natrii Sulfas) and Dahuang (Rhei Radix et Rhizoma) due to advanced age, opting instead for interior-supporting methods or ordinary remedies, and fails to use Bian stones to drain the toxin, relying solely on medicinal power, danger is rarely avoided. (Xu Lingtai stated: Fangfeng Tongsheng San is a formula for treating simultaneous exterior and interior heat, known as the "Dual Resolution Method." It must be applied only after carefully confirming symptoms of simultaneous exterior and interior heat. He also stated: Jingfang Baidu San is the main formula for Shi Du, but Renshen should not be used lightly.)
A man suffered from this condition where exterior and interior symptoms had resolved, leaving only swelling. He was treated with Tuoli Xiaodu San for four doses. Once pus formed, it was lanced, leading to recovery.
A woman suffered from this condition with swelling and pain. After being purged with medicines containing Mangxiao and Dahuang, the pain eased slightly, but returned the next day. Palpation revealed that exterior pathogens had retreated, indicating that blood stasis was recurring into suppuration. She was treated with Tuoli Xiaodu San to promote suppuration and recovery.
A man suffered from head and face swelling and pain. After taking medicines containing Mangxiao and Dahuang to resolve toxicity, his condition worsened. Palpation revealed a floating and rapid pulse, indicating that pathogens were still in the exterior. He was treated with Jingfang Baidu San for two doses, reducing the severity by more than half. He was then treated with Gegen Niubangzi Tang for four doses, resulting in recovery. The *Neijing* states: Swelling above the middle of the body is caused by Heavenly Qi; swelling below the middle of the body is caused by Earthly Qi. Here, pathogens lodge between the Heart and Lungs, attacking upward to the head and eyes, causing swelling. This is caused by contracting abnormal Qi of the four seasons, differing from conditions caused by accumulation of heat from rich foods. Medicines containing Mangxiao and Dahuang should only be used when there is solid constipation. If the cause is not examined, and deficiency/excess and exterior/interior are not distinguished, indiscriminate purging will inevitably lead to error. It is common during famines that people of low status suffer from this, due to damage to Stomach Qi allowing pathogens to act. This must be carefully observed. Generally, for pathogens in the exterior, Gegen Niubangzi Tang, Renshen Baidu San, or Puji Xiaodu Yinzi (Puji Toxin-Resolving Decoction) are used. For pathogens in the interior, Wuli Dahuang Tang or Zhizi Ren Tang (Gardenia Seed Decoction) are used. For unresolved exterior and interior, Fangfeng Tongsheng San is used. For resolved exterior and interior with persistent swelling, Xijiao Shengma Tang (Rhinoceros Horn and Cimicifuga Decoction) is used. For severe swelling, Bian stones are used to puncture the affected area and release evil blood to drain toxin, or Tongqi San (Ventilation Powder) is used to induce sneezing to drain toxin. It heals spontaneously after ten days; if pus and blood are sneezed out, it heals immediately. To promote suppuration, Tuoli Xiaodu San is used; to promote contraction, Tuoli San (Interior-Supporting Powder) is used. This method is the most secure. If after five to seven days the throat swells shut, speech is lost, the head and face do not swell, and taste is absent, it is incurable. (This is due to damp-toxin qi of seasonal epidemics manifesting on the head and face, known as "Da Tou Wen". Because it can suppurate and discharge toxins, it is classified under Surgery.)
A man suffered from this condition. After taking exterior-releasing medicines, his condition intensified with fever and constipation. Palpation revealed a deep and full pulse, indicating pathogens in the interior. He was purged with Dahuang Tang (Rhubarb Decoction), after which interior symptoms receded. He was then treated with Gegen Niubangzi Tang, and edema subsided. Only redness and swelling remained. He was further treated with interior-supporting medicines to promote suppuration and recovery. Qi Shi said: Shi Du is contracted by humans from the pathogenic qi of epidemic toxins of the four seasons. Subsequently, it manifests on the nose, face, ears, nape, and throat, presenting with redness and swelling without a head, or forming nodules with roots, causing aversion to cold, fever, and headache. Or, if limb pain is severe, the mind becomes unsettled, and the throat closes. Ignorant practitioners may mistake it for Shanghan (Cold Damage) and administer resolving medicines. Only after one or two days does the swelling increase before they realize their mistake and seek a surgeon. Originally, this condition had no formulas or discussions in ancient texts. Secularly, it is commonly called Dan Liu (Dan Tumor). Patients dislike the term "Shi Du" for fear of contagion. Examining the classics: Sudden reddening of the body, resembling painted cinnabar, is called Dan Du (Dan Poison). This is caused by wind-heat and evil toxicity, specifically different from Shi Du. Generally, Shi Du begins resembling Shanghan. Within five to seven days, it can be fatal. Practitioners must distinguish it carefully. First, palpate the pulse: slippery, rapid, floating, full, deep, tight, wiry, or choppy are all indicators. Floating and rapid indicate pathogens in the exterior; deep and choppy indicate pathogens are deep. In persons with strong Qi, Huadu Dan (Toxin-Transforming Pill) should be taken urgently to attack the pathogen. If heat is full and bowel movements are obstructed, Dahuang Tang is used to purge. If exterior symptoms exist, Jiedu Shengma Tang (Toxin-Resolving and Cimicifuga Decoction) is used to induce sweating. For those who are elderly and have weak Qi, Wuxiang Lianqiao Tang (Five-Aromatics and Forsythia Decoction) is the primary treatment. Additionally, Tongqi San is blown into the nose to induce over ten sneezes. Caregivers daily use medicine to induce sneezing to prevent contagion. Patients also use sneezing medicine three to five times daily to drain heat toxins. This is an excellent method for treating Shi Du. If unresolved after three or four days, drastic purging should not be used; reconciliation is still appropriate, such as taking Xijiao Lianqiao San (Rhinoceros Horn and Forsythia Powder). By the seventh or eighth day, if urination and defecation are obstructed, and the head and face are swollen, high, and red, Tuoli San and Huangqi San (Astragalus Powder) can be taken. It is advisable to lance and bleed to drain toxic vapors. After ten days, it heals spontaneously without treatment. If within five days the spirit is confused, the throat is closed, speech is lost, the head does not swell, and taste is absent, death is certain, and treatment is futile. However, this disease has Yin and Yang aspects, and can be treated with sweating or purging. Commonly, crude physicians merely say "heat toxin" and use cold-cooling medicines, unaware that diseases vary in severity and treatments have contrary and conforming approaches. This must be carefully considered.
Xu Kaogong, over thirty years old, suffered from ear and facial swelling, chills, fever, and limb stiffness. His pulse was floating and full. This was Shi Du. With pathogens in the exterior, he was treated with Jingfang Baidu San plus Niubangzi and Xuanshen, gradually improving. He was then treated with Shengma, Gegen, Lianqiao, Jiegeng, Chuanxiong, Yinhua (Lonicerae Japonicae Flos), and Niubangzi, leading to complete recovery.
