雨降连绵，久鲜日照，则阴霾之邪，迷漫宇宙，地中湿气上腾，人身之阳易伏，而
阴独盛。凡见邪热化斑病，始终总宜轻散。虽延有日，壮热烦闷，舌不燥，口不渴，似化
热未伤阴，乃阴滞于内，而格阳于外，故热止发于皮肤，不曾伤及胃腑，惟有透阳以和
阴，不当助阴以困阳。若与凉剂，即神昏乱语，烦躁不休矣。且雨泽多，淫湿生寒，每
伤脾土，则中气不运，常见疟痢痹痛霍乱等症，用药喜温忌凉。
喉系于肺，肺开窍于鼻，则鼻外通天气，一触非时厉气，由肺传胃，先见鼻塞，咳嗽，
恶寒，发热，遂喉肿痛腐，其病似喉风。传染他人，甚则耳下漫肿，或肿串左右，牙关
紧胀，痰壅气急，或身发红斑，（肿处宜贴清散膏药。）治法见《青囊集》。下手误进苦寒药，
冰伏风热，随转沿烂，声哑呛咳。（大人费手，小儿不救。）
疔症初起，一疙瘩如粟米，觉麻木痒痛，误食荤腥，即助火生痰，闭毒不出，愈加肿
硬，作疼，是为走黄。有毒走串他处，发如注痰者。（误刺火针成不治。）轻者可治，毒重者不
救。俟至十日外，脓熟痛减，无妨。并搭背，对口，一切火毒，致病皆忌荤腥。
有男女染毒，知欲发疮，畏耻不言，只求速效。每有用轻粉一钱，或升药一钱，加
大枣肉数枚，为丸，分数次，令病患服下者。则患者口舌破腐，咽喉肿痛，难进汤水，时
吐唾涎，十数日，喉口方松，毒收入骨，如油和面。疮虽暂愈，后或数月，或隔几年，毒
又外透。随处生核，或小，或大，皮色如常，隐痛渐破，黑烂极臭，竖头坏肉深嵌，在上
部，用升药、生石膏、黄连、大黄，研细末掺之，贴膏药渐愈。如落膝盖下，暂痊，必
屡发。多服败毒方。可知轻粉、升药，皆水银炼成，性烈助火，入胃灼阴殆尽。医者临
此症，询其生梅毒否，服截毒丸否？方有把握。至此遂遗毒于后嗣。苦邪淫湿火，不由
下泄，每炎炎上烁肺系，喉中肿痛，并无寒热，可进饮食。（倘喉风发寒热，难进饮食。）烂
形似蜂窠，或有臭味，或肿烂及帝丁，甚而烂脱，渐串至鼻，或有鼻烂脱，尽串至唇口，
面目烂者。或有毒攻脑户，烂延头额，此名开天窗者，或有满舌臭烂，如蜂窠，此名舌
疳者。或止鼻孔肿痛，生小红疮，此为鼻疳者。或先由鼻串烂，唇口渐烂通喉者。或止
喉烂，为喉疳者。吹以青霜散，加升药擂匀，方见《青囊集》。外掺遇仙丹，见《青囊集》。
外贴膏药，常服仙遗粮散，以降其毒（方见后）。或止由上唇，外边先烂腐后，便豁嘴串鼻者，
不治。
连绵阴雨，久无日照，导致阴霾邪气弥漫天地，地中湿气上升，人体阳气容易郁伏，而阴气独盛。凡是见到邪热化斑的病证，始终适宜用轻清宣散的方法治疗。虽然病程已延续数日，出现高热烦闷，但舌苔不干燥，口不渴，看似化热但未伤及阴液，实则是阴气阻滞于内，格拒阳气于外，所以发热仅表现在皮肤，未曾伤及胃腑，只有透发阳气以调和阴气，不应当助长阴气而使阳气困顿。如果给予寒凉药剂，就会导致神志昏迷、胡言乱语、烦躁不安不止。况且雨水多，淫湿生寒，常常损伤脾土，导致中焦之气运行不畅，常见疟疾、痢疾、痹痛、霍乱等症状，用药宜温忌凉。
喉部系属于肺，肺开窍于鼻，因此鼻子外通天气，一旦接触非时节的厉气，病邪由肺传入胃，先出现鼻塞、咳嗽、恶寒、发热，随后咽喉肿痛溃烂，病症类似喉风。此病会传染他人，严重时耳下漫肿，或肿胀串连左右，牙关紧闭胀硬，痰液壅塞、气息急促，或者身体发出红斑。（肿胀处适宜贴敷清散膏药。）治疗方法见《青囊集》。若下手误用苦寒药物，会使风热冰伏，随即转为沿烂，声音嘶哑呛咳。（成人治疗棘手，小儿无法救治。）
疔疮初起，有一个如粟米大小的疙瘩，感觉麻木痒痛，误食荤腥食物，就会助火生痰，使毒气闭阻不能透出，更加肿胀坚硬，疼痛，这就是走黄。有毒气走窜他处，发作如注痰者。（误用火针穿刺会导致不治之症。）轻症可以治愈，毒重者无法救治。等到十日后，脓熟痛减，便无妨碍。以及搭背、对口等一切火毒致病，都忌讳荤腥。
有男女感染毒邪，知道要发疮，因羞耻而不说，只求速效。每每有用轻粉一钱，或升药一钱，加入大枣肉数枚，制成丸药，分几次让病患服下的情况。则患者口舌破溃腐烂，咽喉肿痛，难以进食汤水，时常吐唾涎，十几天后，喉口才松弛，毒气深入骨髓，如同油和面混合。疮疡虽然暂时痊愈，后来或许数月，或许隔几年，毒气又向外透出。随处生成肿块，或大或小，皮色如常，隐痛逐渐破溃，黑烂极臭，竖头坏肉深嵌，在上部的，用升药、生石膏、黄连、大黄，研成细末掺撒患处，贴膏药逐渐痊愈。如果落在膝盖以下，暂时痊愈，必定屡次复发。多服用败毒方。可知轻粉、升药，都是水银炼制而成，性质猛烈助火，入胃灼烧阴液几乎耗尽。医者遇到此类病症，询问是否患梅毒？是否服用过截毒丸？才有把握。至此遂将毒遗留给后代。苦于邪淫湿火，不由下泄，往往炎炎上烁肺系，喉中肿痛，并无寒热，可以进食。（倘若喉风发作伴有寒热，难以进食。）溃烂形状似蜂窠，或有臭味，或肿烂波及帝丁（悬雍垂），甚至烂脱，逐渐串连至鼻子，或者有鼻烂脱，尽串连至唇口，面目溃烂的。或者有毒气攻入脑户，烂延头额，这名叫开天窗的；或者有满舌臭烂，如蜂窠，这名叫舌疳的；或者仅鼻孔肿痛，生小红疮，这名叫鼻疳的；或者先由鼻子串烂，唇口逐渐烂通喉咙的；或者仅喉咙溃烂，为喉疳的。吹以青霜散，加升药擂匀，方剂见《青囊集》。外掺遇仙丹，见《青囊集》。外贴膏药，常服仙遗粮散，以降低其毒性（方剂见后）。或者仅由上唇，外边先烂腐后，便豁嘴串鼻的，属不治之症。
Continuous rain and lack of sunlight cause the evil of yin and haze to fill the universe, while dampness from the earth rises. The yang qi of the human body is easily suppressed, leading to an excess of yin. For diseases characterized by pathogenic heat transforming into macules (skin eruptions), light dispersing methods should always be preferred. Although the disease has persisted for days with high fever and restlessness, if the tongue is not dry and there is no thirst, it appears that heat has transformed without damaging yin fluids; however, this is actually yin stagnation internally rejecting yang externally. Thus, heat manifests only on the skin without injuring the Stomach organ. The treatment should focus on venting yang to harmonize yin, rather than assisting yin which would trap yang. If cold-natured formulas are administered, it will lead to coma, delirium, and unceasing irritability. Furthermore, excessive rain generates damp-cold, often injuring Spleen Earth, causing dysfunction of Middle Jiao Qi, manifesting as malaria, dysentery, bi-syndrome pain, cholera, etc.; medications should be warm in nature and avoid cold.
The throat is connected to the Lung, and the Lung opens into the nose; thus, the nose communicates externally with heaven's qi. Upon contact with abnormal pestilential qi out of season, the pathogen transmits from the Lung to the Stomach, initially presenting with nasal congestion, cough, aversion to cold, and fever, followed by sore throat, swelling, and ulceration, resembling wind-throat disease. It is contagious to others; severely, it causes diffuse swelling below the ears or swelling spreading bilaterally, lockjaw, phlegm obstruction with rapid breathing, or red macules on the body. (Swollen areas should be treated with Qing San Gao plaster.) Treatment methods are described in *Qing Nang Ji*. Mistakenly using bitter-cold medicines initially freezes wind-heat, leading to spreading ulceration, hoarseness, and choking cough. (Difficult to treat in adults, incurable in children.)
When a ding carbuncle first appears, it presents as a millet-sized nodule feeling numb, itchy, and painful. Mistakenly consuming meat and fish aids fire and generates phlegm, closing the toxin inside so it cannot exit, becoming more swollen, hard, and painful; this is called "Zou Huang" (running yellow/toxin spreading). If toxic qi spreads to other parts, it may present like pouring phlegm. (Mistaken puncture with fire needles leads to incurable conditions.) Mild cases are treatable; severe toxicity is incurable. After ten days, when pus matures and pain decreases, there is no harm. For all fire-toxin diseases such as back carbuncles and neck carbuncles, meat consumption is taboo.
Men and women infected with toxins who fear shame do not disclose their condition, seeking only quick cures. Some use one qian of Light Powder (Calomel) or one qian of Sheng Yao (Red Sublimate), mixed with several jujube meats, formed into pills taken in divided doses. This causes oral and tongue ulceration, sore throat swelling, difficulty swallowing, and frequent salivation. After over ten days, the throat loosens, but the toxin enters the bone marrow, mixing like oil and dough. Though sores temporarily heal, months or years later, the toxin re-emerges externally. Nodules appear anywhere, varying in size, with normal skin color, slowly breaking open with hidden pain, turning black, rotting, and extremely foul-smelling, with deep embedded necrotic tissue. For lesions on the upper body, apply a fine powder of Sheng Yao, Raw Gypsum, Coptis Rhizome, and Rhubarb, cover with plaster to gradually heal. If located below the knee, temporary cure is followed by frequent recurrence; take Du Jin Fang (Toxin-Resolving Formula) frequently. Note that Light Powder and Sheng Yao are refined from mercury, possessing fierce properties that aid fire and scorch yin fluids upon entering the stomach. When encountering such cases, physicians must inquire about syphilis history or prior use of toxin-blocking pills to ensure accurate diagnosis. Such negligence leaves toxins for future generations. Bitter, lascivious, damp-fire evils, failing to drain downward, blaze upward scorcing the Lung system, causing sore throat and swelling without chills or fever, allowing normal diet. (If wind-throat presents with chills/fever and inability to eat, prognosis is poor.) Ulcers resemble honeycombs, may have odor, or swell and rot involving the uvula, even detaching, spreading to the nose, or causing nasal detachment spreading to lips and mouth, facial ulceration. Toxin attacking the brain gate spreading to forehead is called "Opening the Sky Window"; full tongue foul ulceration like honeycomb is called "Tongue Chan"; nasal swelling/pain with small red sores is called "Nose Chan"; nasal spreading to lips/mouth/throat; or isolated throat ulceration called "Throat Chan". Apply Qing Shuang San mixed with Sheng Yao (see *Qing Nang Ji*). Externally apply Yu Xian Dan (see *Qing Nang Ji*). Apply plaster externally, take Xian Yi Liang San orally to reduce toxicity (formula see later). If ulceration starts on the outer upper lip, causing hare-lip spreading to nose, it is incurable.
