《温热论》曰∶温邪上受，首先犯肺，逆传心包。
华岫云曰∶风温、湿温之时感者，邪从口鼻而入，故曰上受。若春温之由冬时伏寒藏于少阴者，又非上受也。按伤
寒从毛窍而入，温病从口鼻而入，二语世莫不奉为定案矣。其实二者亦皆互有，而总以从毛窍入者为多，南人中焦湿热
素盛，一感温邪，即表里合一，遂似全从口鼻而入，亦不察之甚也。若果尽从口鼻而入，何以治法中有汗法乎？本文上
受二字，即《内经》邪气在上之义。
附时人陆平一语:
外邪伤人，或袭皮毛，或入口鼻，皆受自表也。近人强指温病必从口鼻入，一若分疆划界。温气必不许从皮毛从者，
未免可笑。
《温热论》曰∶伤寒多有变证，温热虽久，总在一经为辨。
此义世皆以手足经释之，非也。伤寒亦有不传经者，但传经者多，温病传经者少。所以然者，寒邪为敛，其入以渐，
进一境即转一象，故变证多；温邪为开，重门洞辟，初病即常兼二三经，再传而六经已毕，故变证少也。
吴鞠通本顾景文“温邪上受、首先犯肺、逆传心包”之十二字，而为《温病条辨》。自条自辨，可发一笑者也。开

The *Wen Re Lun* (Treatise on Warm-Heat) states: "Warm-pathogens enter from the upper orifices, first attacking the Lung; if the condition deteriorates, it reversely transmits to the Pericardium."
Hua Xiuyun stated: "Wind-Warmth and Damp-Warmth are seasonal pathogens that enter through the mouth and nose, hence termed 'entering from above.' However, Spring-Warmth, caused by latent cold hiding in the Shaoyin channel during winter, does not fit this description of 'entering from above.'" It is widely accepted as a definitive rule that Cold damage enters through hair follicles, while Warm diseases enter through the mouth and nose. In reality, both pathways overlap, but entry via hair follicles is more common. People in the South often have abundant damp-heat in the Middle Jiao (Middle Burner); once they contract warm pathogens, the exterior and interior become involved simultaneously, making it appear as though the pathogen entered entirely through the mouth and nose. This is due to a lack of careful observation. If pathogens indeed entered solely through the mouth and nose, why would treatment methods include diaphoresis (sweating therapy)? The term "entering from above" in this text corresponds to the meaning of "pathogenic factors affecting the upper body" in the *Nei Jing* (Inner Canon).
A contemporary, Lu Pingyi, added:
"When external pathogens injure the human body, whether they attack the skin and hair or enter the mouth and nose, they all affect the exterior. Recent scholars insist that warm diseases must enter through the mouth and nose, drawing strict boundaries. To claim that warm qi absolutely cannot enter through the skin and hair is laughable."
The *Wen Re Lun* states: "Cold damage often presents with transformed syndromes; although warm-heat diseases may persist for a long time, they generally remain within one stage/channel for differentiation purposes."
The world interprets this using the twelve channels of the hand and foot, which is incorrect. Cold damage also has cases where transmission between channels does not occur, but transmission is frequent. Conversely, transmission in warm diseases is rare. The reason is that Cold pathogens are contracting in nature; their invasion is gradual. As they advance into each new level, the clinical presentation changes, leading to many transformed syndromes. Warm pathogens are expansive in nature; the defensive gates are wide open. At the onset, the disease often involves two or three channels simultaneously. After further transmission, all six channels are affected, resulting in fewer transformed syndromes.
Wu Jutong based his *Wen Bing Tiao Bian* (Systematic Differentiation of Warm Diseases) on Gu Jingwen's twelve characters: "Warm-pathogens enter from the upper orifices, first attacking the Lung; if the condition deteriorates, it reversely transmits to the Pericardium." Self-questioning and self-answering, it is quite amusing. The book opens by fabricating that Gui Zhi Tang (Cinnamon Twig Decoction) is the primary treatment for warm diseases, falsely attributing it to Zhang Zhongjing's original text. It then cites an error from the Summerheat section of Yang's case in *Lin Zheng Zhi Nan Yi An* (Clinical Guide to Medical Cases), claiming that Zhang Zhongjing differentiated Cold damage by the Six Channels and Liu Hejian investigated Warm heat by the Triple Burner. Wu uses this to illustrate Western Chang's method for treating plague, asserting it represents Liu Hejian's approach to treating warmth. However, Liu Hejian's treatments were discussed only in terms of the Six Channels; the term "Triple Burner" never appears in his *Liu Shu* (Six Books). These two errors speak for themselves. Furthermore, he shifts the root of warm diseases located in the Middle Jiao to the Upper Jiao, declaring that Middle Jiao medications must absolutely not be used. How tragic! [He rejects] Huang Qin (Scutellaria Root) and Lian Qiao (Forsythia Fruit) of the Middle Jiao. Immediately after, he states that prolonged retention of heat pathogens consumes True Yin, and long-standing heat causes "armor-like scaling" of the skin. These are statements made by Wu Jutong himself to others. Initially, he formulated Yin Qiao San (Honeysuckle and Forsythia Powder) [ingredients: Lian Qiao, Bo He, Jie Sui, Yin Hua, Zhu Ye, Dan Dou Chi, Jie Geng, Gan Cao, Niu Zi] and Sang Ju Yin (Mulberry Leaf and Chrysanthemum Drink) [ingredients: Xing Ren, Lian Qiao, Bo He, Sang Ye, Ju Hua, Jie Geng, Gan Cao, Wei Gen]. Neither formula uses a single herb from Gu Jingwen's mild acrid-cool agents; Wu merely extended them. Subsequently, he named formulas "An Gong," using Xi Jiao (Rhinoceros Horn) and Niu Huang (Calculus Bovis) [i.e., An Gong Niu Huang Wan, containing Niu Huang, Yu Jin, Xi Jiao, Huang Lian, Zhu Sha, Bing Pian, She Xiang, Zhen Zhu, Shan Zhi, Xiong Huang, Jin Bo, Huang Qin; and Qing Gong Tang contains Xuan Shen Xin, Lian Zi Xin, Zhu Ye Juan Xin, Lian Qiao Xin, Xi Jiao Jian, Lian Xin Mai Dong]. He named another "Zeng Ye," using Xuan Shen and Mai Dong [i.e., Zeng Ye Tang, containing Xuan Shen, Mai Dong, Xian Sheng Di], as well as the Fu Mai Tang variants with One, Two, and Three Shells [Jia Jian Fu Mai Tang uses Zhi Cao, Gan Di, Bai Shao, Mai Dong, E Jiao, Ma Ren; Yi Jia Fu Mai Tang removes Ma Ren and adds Mu Li from Jia Jian Fu Mai Tang; Er Jia Fu Mai Tang adds Bie Jia to Mu Li; San Jia Fu Mai Tang adds Gui Ban to Bie Jia]. Also Xiao Ding Feng Zhu [Ji Zi Huang, E Jiao, Gui Ban, Tong Bian, Dan Cai] and Da Ding Feng Zhu [Bai Shao, E Jiao, Gui Ban, Gan Di, Ma Ren, Wu Wei Zi, Mu Li, Mai Dong, Zhi Cao, Ji Zi Huang, Bie Jia]. These are nothing but cloying and greasy substances that damage Yin and trap pathogens inward, rendering the condition incurable. Yet, in his Middle Jiao chapter, he occasionally uses Huang Qin, Huang Lian, Shi Gao, and Da Huang. Whenever these herbs are used in warm diseases, they effectively dispel pathogens and reduce heat. Wu Jutong knew this well. However, had he not positioned the pathology in the Upper Jiao, the heat might not have lingered so long, nor would True Yin necessarily have been consumed. Had he not condemned Huang Qin and Huang Lian, the heat might not have lingered, nor would armor-like scaling have occurred. Gu Jingwen allowed the illness to drag on for days; Wu Jutong added the word "slowly/gradually." Why "slowly"? This seems inexplicable, yet it is understandable. This explains why practitioners following Wu Jutong refuse to abandon his methods. Using cloying herbs that retain pathogens and prolonging the course slowly, when heat is at its peak, Yin is inevitably damaged, and death is inevitable. Tao Jie'an's books *Yi Ti Jin*, *Sha Che Chui*, and *Jie Jiang Wang* have extremely malicious names; similarly, the One-, Two-, and Three-Shell Fu Mai Tangs and Ding Feng Zhu formulas have equally malicious names. Medicine is a grave matter, and physicians hold a serious profession; how can they treat it so frivolously?
