发表，大攻里，发表则重虚其阳，攻里则重虚其阴，必致夭亡。产后久病，固不宜大汗大下，设病势危笃，又当从权也。
感冒 感冒者，非冬时正伤寒也，今人不分感冒与正伤寒，一概混治者多矣。盖
冬中杀厉之气，名正伤寒，春秋夏则为温
为凉为暑，何得有寒？间有非时寒邪，人或感之，名曰感冒。既曰感冒，则所病非
轻，亦不得用冬时正伤寒辛甘辛温之药，当用微辛凉以解之。（如紫苏、干葛、羌活之类。）况
人春夏皮肤缓而腠理疏，则邪易入，或劳力汗出而遇微寒，或自外卸衣，或畏暑贪
凉，或天时暴寒，皆能伤之，其证鼻塞清涕，咳嗽头痛，身微发热微恶寒，此感冒
证也。又何得谓之伤寒哉！或曰∶夏天既无寒，间有阴证而用四逆汤何也？曰∶夏
月三阴在内用事，此人必有房事致肾经空虚，或食冷物，径中本经而成此证，足者
阴经所过之处，或者履寒水径中本经之络而成此证，则不谓夏月有寒，此自伤之也，
发表（使用发汗法解表），大攻里（使用峻下法通腑），发汗则严重耗伤阳气，攻下则严重耗伤阴液，必然导致早亡。产后或久病患者，本来就不宜使用大汗或峻下的方法，但如果病势危急，也应当权变处理。
感冒：所谓的“感冒”，并不是冬季感受的“正伤寒”。现在的人不分感冒与正伤寒，大多混为一谈进行治疗。冬季的凛冽寒气，称为“正伤寒”；而在春、夏、秋季，气候分别为温、凉、暑，怎么会有寒邪呢？偶尔有非时节的寒邪，人若感之，称为“感冒”。既然称为感冒，说明所患之病并非轻微，也不得使用治疗冬季正伤寒所用的辛甘、辛温药物，而应当使用微辛凉的药物来解除。（如紫苏、干葛、羌活之类。）况且人在春夏季节皮肤松弛、腠理疏松，邪气容易侵入；或者因劳累用力出汗后遭遇微寒，或者从外面回来脱下衣服，或者因为怕热贪凉，或者天气突然变冷，都能造成伤害。其症状表现为鼻塞流清涕、咳嗽、头痛、身体微微发热、微微恶寒，这就是感冒证。又怎么能称之为伤寒呢！有人问：夏天既然没有寒邪，为什么偶尔见到阴证而使用四逆汤呢？回答说：夏季三阴经（太阴、少阴、厥阴）之气在内主事，这种人必定是因为房事导致肾经空虚，或者食用生冷食物，直接损伤本经而成此证；或者是脚部经过寒冷的水域，直接损伤本经的络脉而成此证，这不能说是夏天有寒邪，这是自身伤害所致。
Releasing the exterior (using diaphoresis to resolve the exterior) and vigorously purging the interior (using drastic catharsis to unblock the bowels): releasing the exterior severely depletes Yang Qi, while purging the interior severely depletes Yin fluids; this will inevitably lead to premature death. For patients postpartum or suffering from chronic illness, drastic sweating or purging is generally contraindicated; however, if the disease condition is critical, one must apply flexible treatment principles.
Ganmao (Common Cold): "Ganmao" does not refer to "Zheng Shanghan" (True Cold Damage) contracted in winter. Nowadays, many people fail to distinguish between Ganmao and Zheng Shanghan, treating them indiscriminately. The biting cold qi of winter is called "Zheng Shanghan"; whereas in spring, summer, and autumn, the climates are warm, cool, and hot respectively, how can there be cold? Occasionally, non-seasonal cold pathogenic factors may affect a person, which is termed "Ganmao". Since it is called Ganmao, the illness is not trivial, and one must not use the acrid-sweet or acrid-warm herbs used for treating winter's Zheng Shanghan. Instead, slightly acrid-cool herbs should be used to resolve it (such as Perilla Fructus [Zisu], Puerariae Radix [Gange], Notopterygii Rhizoma et Radix [Qianghuo]). Moreover, during spring and summer, human skin is loose and interstices (Couli) are open, making it easy for pathogens to enter. This can occur after labor and sweating when exposed to slight cold, or upon removing clothes after returning from outside, or due to seeking coolness because of heat, or sudden cold weather, all of which can cause injury. The symptoms include nasal congestion with clear discharge, cough, headache, slight fever, and slight aversion to cold; this constitutes the Ganmao syndrome. How can this be called Shanghan! One might ask: If there is no cold in summer, why is Sini Tang (Four Reversal Decoction) occasionally used for Yin syndromes? The answer is: In summer, the Qi of the Three Yin meridians (Taiyin, Shaoyin, Jueyin) dominates internally. Such a person likely has emptiness in the Kidney Meridian due to sexual activity, or has ingested cold foods, directly injuring the affected meridian. Or, perhaps the feet passed through cold water, directly injuring the collaterals of the affected meridian. This condition arises from self-injury, not because there is cold in summer.
