吕祖曰∶妙论如见，吾不能言之矣。
李白大仙说：我阅读医书，认为伤寒门最为紧要。两感证和隔经证，前人的书中已经明确说明不论治之外，现在（讨论）发狂、登高而歌、弃衣而走等症状。
治疗伤寒发斑的方剂：凡是遍身发斑的，病情看似严重反而较轻；只有心窝部发斑的，看似轻微反而严重。心窝部发斑者，是因为热邪存留于心中。方用：人参三钱，必须滋养心神以调和气血。
结胸且烦躁不安的是死症，不可攻下，即使攻下也是死症。所谓结胸烦躁，是胃气即将断绝的表现，胃气绝则津液如何生成？津液既然不能生成……
方用：天花粉五钱，枳壳一钱，陈皮五分，麦芽三钱，天门冬三钱，桑白皮三钱，神曲三钱。枳壳、花粉能迅速消除痞结。
有脏结的症状，记载在太阳经中，其实并非太阳经。为什么记载在太阳经呢？正是为了辨别太阳经中有类似症状但实质不同的情况……
方用：白术五钱，甘草一钱，附子一钱，当归一钱，肉桂五分。水煎服。白术能通利腰脐部位的气机，人参能挽救元阳的断绝，当归能活血周身，甘草能调和脾胃以定痛，附子和肉桂能散寒祛邪，脏腑内部既已温暖，结滞自然消散。
如果有人出现直视、谵语、喘满、下利，这是死症。如果还有一脏之气未绝，还可以治疗。方用：石膏五钱，人参……止……
伤寒坏病，已经发汗、已经催吐、已经攻下，但身体仍然发热，这是不治之症。现在特别传承此方，以补救上述三种误治的失误。方用……归五……生也……
少阴病，恶寒、身体蜷缩并伴有下利，是不治之症。阳气即将断绝，急需使用补阳的药物来挽回。方用：人参二……痊愈……
呕吐和下利同时发作、烦闷、手足四肢逆冷，是死症。然而如果在早期治疗，未必不能救活。方用：人参二两……
下利虽然停止，但头眩昏晕，这也是死症。阳气虽然回复但阴气已绝，现在因为阴气绝，导致诸阳之气上聚于头部，阳气尚未……
四肢逆冷、恶寒、身体蜷缩、脉象摸不到、不烦躁但感觉燥扰，本是死症。之所以认为可救，是因为脉象虽不至，但不烦躁而仅燥扰，说明阳气未绝……心……
呼吸浅表高促见于发病六七天之间，这是少阴病，不是太阳病。息高，是指鼻息微弱。这是因为下元的真气欲脱……两……也。
伤寒少阴病，脉象微细沉，想睡觉，出汗且不烦躁，自己想要呕吐，到了五六天出现自利，又烦躁不能卧的，是死症……两……
脉迟属于寒证，误用黄芩汤会使寒气更重。寒气极盛反而能进食，病名叫做“除中”。胃寒再加上寒凉药物，反而导致能食的现象……气除……肉桂……
伤寒六七天，脉微、手足厥冷、烦躁，厥冷不回转的，是死症。阴证发厥，灸其厥阴经，也是不得已的办法……参附……服，从脐始……
伤寒发热而伴有厥冷的，便有生机，因为邪气向外排出。然而厥冷可以偶尔发生一两次，不可以频频发作，如果下利非常严重，如何可以……通达……煎服……
伤寒热六七天没有下利，忽然出现下利的，是危症。何况出汗不止呢？这是亡阳。有阴无阳，死症很明显了……生。钱。
下利、手足厥冷、无脉，情况紧急。关元穴的脉气，非艾灸不能引出。艾灸之后，脉仍不出，反而出现微喘……三钱，熟地五钱，甘草一钱，附子一钱，名为还脉汤。服用一剂后脉象就出来的会死，如果脉象渐渐出来的还有希望完全康复……
伤寒下利十余次，脉象反而实有力的，是死症。为什么呢？亡阳应当脉象虚弱，反而不虚，呈现假实的现象……是正……也。方用……
吕祖说：精妙的论述如同亲眼所见，我已经无法再言语了。
Li Bai, the Great Immortal, said: "I have read medical books and believe that the section on Cold Damage (Shanghan) is of utmost importance. Cases of 'Liang Gan' (simultaneous involvement of exterior and interior meridians) and 'Ge Jing' (cross-meridian transmission) are already explicitly excluded in previous texts. Now, regarding symptoms such as mania, climbing high and singing, or discarding clothes to run about..."
For treating macules (skin eruptions) caused by Cold Damage: If macules appear all over the body, the condition appears severe but is actually mild; only if macules appear in the epigastrium (heart pit), does it appear mild but is actually severe. Epigastric macules indicate heat retained in the Heart. The prescription uses: Ren Shen (Ginseng Root) 3 qian, which must nourish the Heart Spirit to harmonize Qi and Blood.
In cases of Jie Xiong (chest binding/painful mass) accompanied by irritability, it is a death syndrome; purgation is contraindicated, and even if used, it leads to death. Such Jie Xiong with irritability indicates the impending extinction of Stomach Qi. If Stomach Qi is extinct, how can Body Fluids be generated? Since Body Fluids cannot be generated...
The prescription is: Tian Hua Fen (Trichosanthes Root) 5 qian, Zhi Ke (Aurantium Fruit) 1 qian, Chen Pi (Tangerine Peel) 5 fen, Mai Ya (Barley Sprout) 3 qian, Tian Men Dong (Asparagus Tuber) 3 qian, Sang Bai Pi (Mulberry Root Bark) 3 qian, Shen Qu (Medicated Leaven) 3 qian. Zhi Ke and Tian Hua Fen rapidly resolve stagnation.
There is a syndrome called Zang Jie (visceral knotting), recorded under the Taiyang Meridian, but it is actually not a Taiyang disease. Why is it recorded under Taiyang? Precisely to differentiate Taiyang conditions that present with similar symptoms but different pathologies...
The prescription is: Bai Zhu (Atractylodes Rhizome) 5 qian, Gan Cao (Licorice Root) 1 qian, Fu Zi (Aconite Lateral Root) 1 qian, Dang Gui (Angelica Sinensis Root) 1 qian, Rou Gui (Cinnamon Bark) 5 fen. Decoct in water and take orally. Bai Zhu promotes the movement of Qi in the waist and umbilical region; Ren Shen rescues the extinction of Primordial Yang; Dang Gui invigorates blood throughout the body; Gan Cao harmonizes the Middle Jiao to alleviate pain; Fu Zi and Rou Gui dispel cold and expel pathogens. Once the internal viscera are warmed, the knotting will naturally dissipate.
If a person presents with fixed staring, delirious speech, wheezing and chest fullness, and diarrhea, it is a death syndrome. However, if the Qi of one Zang organ has not yet perished, it may still be treatable. The prescription uses: Shi Gao (Gypsum Fibrosum) 5 qian, Ren Shen... to stop...
In complicated cases of Cold Damage (Huai Zheng), where the patient has already undergone sweating, vomiting, or purging, yet fever persists, it is an untreatable syndrome. Here, this special prescription is transmitted to remedy the errors of these three methods. The prescription uses... Gui... Sheng ye...
In Shaoyin disease, aversion to cold, curling up of the body, and diarrhea constitute an untreatable syndrome. When Yang Qi is about to perish, urgent use of Yang-tonifying herbs is required to reverse the condition. The prescription uses: Ren Shen 2... recovery...
When vomiting and diarrhea occur simultaneously, accompanied by stifling sensation and cold limbs (Si Ni), it is a death syndrome. However, if treated early, rescue is possible. The prescription uses: Ren Shen 2 liang...
Although diarrhea has ceased, dizziness and vertigo persist; this is also a death syndrome. Although Yang Qi has returned, Yin Qi is extinct. Due to the extinction of Yin, all Yang Qi gathers at the head, and Yang has not yet...
Cold limbs, aversion to cold, curling up of the body, absence of pulse, no irritability but restlessness, is originally a death syndrome. It is considered salvageable because although the pulse is absent, the lack of irritability suggests Yang has not completely perished... Heart...
Rapid, shallow breathing appearing between the sixth and seventh days indicates Shaoyin disease, not Taiyang disease. 'Xi Gao' refers to weak nasal respiration. This results from the depletion of True Qi in the lower Yuan... Liang... ye.
In Cold Damage Shaoyin disease, if the pulse is faint, fine, and deep; the patient desires to sleep; there is sweating without irritability; and spontaneous desire to vomit; progressing to day five or six with spontaneous diarrhea, followed by irritability and inability to lie down, it is a death syndrome... Liang...
A slow pulse indicates cold; mistakenly using Huang Qin Tang exacerbates the cold. Extreme cold presenting with the ability to eat is named 'Chu Zhong' (removal of the middle). Adding cold-natured herbs to a cold stomach paradoxically leads to appetite... Qi Chu... Rou Gui...
In Cold Damage, if six or seven days pass with a faint pulse, cold limbs, and irritability, and the cold limbs do not recover, it is a death syndrome. For cold syndromes presenting with cold limbs, moxibustion on the Jueyin meridian is a last resort... Can Fu... fu, starting from the navel...
In Cold Damage, fever accompanied by cold limbs indicates a potential for survival, as pathogens are moving outward. However, cold limbs may occur occasionally once or twice, but not frequently. If diarrhea becomes severe, how can one... penetrate through... decoct and take...
If Heat persists for six or seven days without diarrhea, but suddenly diarrhea occurs, it is a critical syndrome. Especially if sweating continues incessantly, this indicates collapse of Yang (Wang Yang). With Yin present but Yang absent, death is evident... Sheng. Qian.
Diarrhea with cold limbs and absence of pulse is urgent. The Qi of the Guan Yuan point cannot emerge without moxibustion. After moxibustion, if the pulse still does not return and slight panting occurs... 3 qian, Shu Di (Prepared Rehmannia Root) 5 qian, Gan Cao 1 qian, Fu Zi 1 qian, named Huan Mai Tang (Pulse-Restoring Decoction). If the pulse returns after one dose, death ensues; if the pulse gradually returns, full recovery is hoped for...
In Cold Damage, if there is diarrhea more than ten times daily but the pulse is surprisingly forceful/excess, it is a death syndrome. Why? Collapse of Yang should present with a weak pulse; if it is not weak but shows a false excess appearance... is Zheng... ye. The prescription uses...
