气不足，不能逐邪外出，则毒伏于内，喘胀而死者，是欲名闷痧也。
疹为胎毒发于心，肺与相连热毒侵，咳嗽鼻中清涕出，且观双目泪盈盈。
斑疹须明岁气先，勿轻汗下作伤寒，察人虚实施力法，莫犯天和损寿元。
疹喜清凉痘喜温，能知疹痘不同伦，疹苗痘实无人解，脏腑阴阳各自分。
过期不出势淹延，毒伏身中出见难，急用透肌休怠玩，岂堪脏腑受熬煎。
蒸蒸发热咳声频，目胀而浮气上行，坐卧不安痰唾少，肺焦叶举热邪侵。
火热重蒸汗润身，毒邪并迫血达经。汗多卫表邪从散，血去荣中毒少轻。
痘疮亦艳养来攻，疹子红鲜毒易松，白疹血虚犹可疗，黑斑候恶莫相逢。
疹家出没合阴阳，出以温和没以凉，连出不收阳气盛，迟迟间出是阴强。
头面部及两侧腮颊部位皮疹难以透发出来的，病情严重；感受风邪后未能及时治疗的，病情严重；两侧腮颊部位皮疹颜色呈紫色且成片出现的，病情严重；麻疹中夹杂斑疹，伴有气机上逆的，病情严重；皮疹颜色红紫、晦暗且干燥的，病情严重；咽喉肿痛，无法进食的，病情严重；热邪移入大肠导致变为痢疾的，病情严重。
皮疹颜色黑暗干枯，一出即隐没的，属于不治之症。鼻孔扇动、口张、眼神无神的，属于不治之症。鼻色青黑、粪便黑色的，属于不治之症。热势极盛导致气喘胸胀、胸部高耸、肩部呼吸（抬肩以助呼吸）、胡言乱语、鼻出血、手足抽搐、摇头、意识模糊（如寻衣摸床）、呃逆、厌恶饮食、便秘、口中呼出粪臭气的，属于不治之症。气喘且心前区吸气困难的，属于不治之症。头面部不出疹的，属于不治之症。
麻疹后期出现牙疳（牙龈腐烂）有五种情况属于不治之症：气味臭烂的，不治；病邪由外向内传变的，不治；没有脓血的，不治；牙齿白色的，这是胃腑腐烂的表现，不治；牙齿脱落的，这是肾气败绝的表现，不治。一旦正气不足，不能将邪毒驱逐外出，则毒邪潜伏于体内，导致气喘胸胀而死，这种病症被称为“闷痧”。
麻疹是胎毒发于心，与肺相连，热毒侵袭，会出现咳嗽、鼻流清涕，还要观察双眼是否泪汪汪。
诊治斑疹必须明了当年的岁气（气候特点），不要轻易使用发汗或攻下法当作伤寒治疗，要察辨病人的虚实来实施治疗方法，不要触犯天和之气而损害寿命根本。
麻疹喜欢清凉，痘疮喜欢温补，能知道麻疹和痘疮的不同之处，麻疹的形态轻浅而痘疮的形态充实，脏腑阴阳各自不同。
过期不出，势头拖延，毒邪伏在身体中难以透出，急需使用透肌发表的方法，不可懈怠玩忽，怎能忍受脏腑受到煎熬。
蒸蒸发热，咳嗽频繁，眼睛胀痛且浮肿，气机上行，坐卧不安，痰唾少，这是肺叶焦枯，热邪侵袭。
火热重蒸，汗水湿润身体，毒邪并迫，血液通达经络。汗多则卫表之邪随之消散，血去则营中毒邪减轻。
痘疮也艳丽，需要养护来攻治；麻疹子红鲜，毒邪容易松解；白色麻疹因血虚尚可治疗，黑色斑疹预后恶劣，不要相逢（遇到）。
麻疹患者的出没符合阴阳规律，出疹时用温和之法，隐没时用清凉之法；连续发出而不收敛，是阳气过盛；迟迟间断发出，是阴气偏强。
If the rash on the head, face, and both cheeks is difficult to erupt, the condition is severe; if wind-cold was contracted and treatment was delayed, the condition is severe; if the rash on both cheeks appears purple and in patches, the condition is severe; if macules are mixed with papules and there is rebellious Qi, the condition is severe; if the rash is red-purple, dark, and dry, the condition is severe; if there is soreness and swelling of the throat with inability to eat, the condition is severe; if heat transfers to the Large Intestine causing dysentery, the condition is severe.
If the rash is dark, black, and dry, disappearing immediately upon eruption, it is incurable. If the nostrils are flaring, the mouth is open, and the eyes lack spirit, it is incurable. If the nose is cyanotic and the stool is black, it is incurable. If extreme heat causes panting and chest distension, high chest, shoulder breathing (using accessory muscles), delirium, epistaxis, hand clenching, head shaking, picking at bedclothes, hiccups, aversion to food, constipation, and breath smelling like feces, it is incurable. If panting occurs with suction at the precordium, it is incurable. If no rash appears on the head and face, it is incurable.
For post-rash gingival gangrene (Ya Gan), there are five incurable conditions: foul rotting odor is incurable; pathogen moving from exterior to interior is incurable; absence of pus and blood is incurable; white teeth indicate stomach tissue decay and are incurable; falling teeth indicate kidney failure and are incurable. Once righteous Qi is insufficient to expel pathogens outward, toxins remain latent inside, leading to death from panting and chest distension; this condition is called "Men Sha" (Stifling Miasma).
Measles stem from fetal toxin originating in the Heart, connected to the Lung, where heat-toxin invades, causing coughing, clear nasal discharge, and watery eyes.
When diagnosing macules and papules, one must first understand the annual climate (Sui Qi); do not lightly use sweating or purging methods as for Taiyang disease (Shang Han). Observe the patient's deficiency or excess to apply appropriate methods, and do not violate the Harmony of Heaven, damaging longevity.
Measles prefers coolness, while smallpox prefers warmth; knowing their differences is crucial. Measles lesions are superficial, smallpox lesions are substantial; the Zang-Fu organs and Yin-Yang are distinct.
If overdue and not erupting, the course drags on, and toxins trapped within are hard to release. Urgently use methods to vent the skin; do not neglect, lest the Zang-Fu suffer torment.
With steaming fever and frequent coughing, swollen and floating eyes, rising Qi, restlessness, and scanty phlegm, the Lung leaves are scorched due to heat-toxin invasion.
Intense heat steams, moistening the body with sweat; pathogens force blood into the meridians. Excessive sweat disperses Wei-level pathogens; loss of blood reduces Ying-level toxicity.
Smallpox lesions are also vibrant, requiring nourishment to attack; measles lesions are bright red, allowing toxins to loosen easily. White measles due to Blood deficiency can still be treated; black macules indicate a dire prognosis, avoid encountering them.
The emergence and disappearance of measles conform to Yin and Yang. Eruption should be treated with mild methods, disappearance with cool methods. Continuous eruption without receding indicates excessive Yang; slow, intermittent eruption indicates strong Yin.
