切忌发汗及吐下，盖元气盛，则邪不能为害，传遍经络自愈。仲景不敢补，反攻邪气，致正气受伤，误人
多矣。凡遇此证，只用姜附汤多服，自然解散。（元虚而受攻伤正，何必老人，仲景医之圣者，宁不知此。）
凡伤寒阳证欲作汗，阴证已加灸，真元欲复，与邪气分争，必发寒战，鼻衄昏迷，牙关微紧，四肢微厥，
乃阴阳换气也。一二时辰，自然腋下汗出而愈。（阴阳换气，即今之所谓战汗，须预告病家，令其不必惊骇，
否则阖室苍惶，谗言蜂起，彼时一剂误投，遂有生死之判。）
凡伤寒谵语，属少阴，仲景属阳明误也。阳明内热必发狂，今止谵语，故为少阴。（仲景皆指神虚，未尝
不属少阴也。）急灸关元三百壮，若灸后，仍不止者死。
凡鼻衄不过一二盏者，气欲和也，不汗而愈。若衄至升
斗者，乃真气脱也，针关元入三寸，留二十呼，血立止；再灸关元二百壮，服金液丹。不然恐成虚劳中满。
（当解、当清、当温、当补，审证施治，庶几无误。）
伤寒瘥后，饮食起居劳动则复发热。其候头痛、身热、烦躁，或腹疼，脉浮而紧，此劳复也。服平胃散、
分气丸，汗出而愈。若连服三四次不除者，此元气大虚故也，灸中脘五十壮。（劳复证仲景数方，用须斟酌，
第一须审邪气之有无，辨寒热之多寡，以施治则无误矣。）
切忌使用发汗、催吐及泻下法，因为元气充足，邪气就无法造成危害，病邪传遍经络后自然会痊愈。张仲景不敢采用补法，反而攻伐邪气，导致正气受损，误人害命的情况太多了。凡是遇到这种情况，只需多服用姜附汤，病邪自然就会消散。（元气虚弱而受到攻伐损伤正气，这哪里只是老人如此，即使是像张仲景这样的医学圣人，难道不知道这一点吗？）
凡是伤寒阳证想要出汗，阴证已经施灸，真元即将恢复，与邪气相互抗争时，必然会出现寒战、鼻出血、昏迷、牙关微微紧闭、四肢微微厥冷等症状，这是阴阳之气进行转换的表现。经过一两个时辰，腋下自然出汗，病就好了。（阴阳之气转换，就是现在所说的“战汗”，必须提前告知病人家属，让他们不要惊慌害怕，否则全家惶恐不安，谣言四起，那时如果误投一剂药，就会有生死的区别。）
凡是伤寒出现胡言乱语的症状，属于少阴经病，张仲景将其归为阳明经病是错误的。阳明经内热严重一定会导致发狂，现在只是胡言乱语，所以属于少阴经。（张仲景所说的神志恍惚，未尝不属于少阴经病。）急需艾灸关元穴三百壮，如果灸后症状仍不停止，就会死亡。
凡是鼻出血不超过一两盏量的，是气血将要调和的表现，不出汗也会痊愈。如果出血达到升斗之多，是真气脱失的表现，针刺关元穴进针三寸，留针二十次呼吸的时间，血立刻停止；再灸关元穴二百壮，服用金液丹。不然恐怕会形成虚劳和中满病症。（应当解表、应当清热、应当温中、应当补益，仔细审察证候进行治疗，才差不多不会出错。）
伤寒病愈之后，因饮食、起居或劳动过度而再次发热。其表现为头痛、身体发热、烦躁不安，或者腹痛，脉象浮而紧，这就是劳复症。服用平胃散、分气丸，出汗后痊愈。如果连续服用三四次仍不能消除症状，这是因为元气大虚的缘故，艾灸中脘穴五十壮。（劳复症张仲景有多个方剂，使用时需要斟酌，第一必须审察邪气是否存在，辨别寒热的多少，按照此原则治疗就不会出错了。）
It is strictly forbidden to use methods of inducing sweating, vomiting, and purging. When the primordial qi (Yuan Qi) is robust, pathogenic factors cannot cause harm, and the disease will resolve spontaneously after spreading through the meridians. Zhang Zhongjing dared not employ tonification, but instead attacked the pathogenic factors, thereby injuring the healthy qi, leading to numerous cases of medical error. In such cases, one should simply administer large doses of Jiang Fu Tang (Ginger and Aconite Decoction), and the pathogens will naturally dissipate. (When primordial deficiency is compounded by injury from attacking treatments, this applies not only to the elderly; even Zhang Zhongjing, a sage of medicine, surely knew this.)
In cases of Yang-pattern Shanghan where sweat is about to occur, or Yin-pattern Shanghan where moxibustion has been applied, as the true yuan recovers and contends with pathogenic factors, chills, epistaxis, coma, slight rigidity of the jaw, and slight coldness of the four limbs will inevitably manifest. This represents the transformation of yin and yang qi. After one or two hours, sweat will naturally appear in the axillae, and the patient will recover. (The transformation of yin and yang qi refers to what is now called "battle sweat." It is necessary to warn the patient's family in advance so they do not panic; otherwise, the household will be in turmoil, rumors will spread, and a misprescribed dose at that critical moment could determine life or death.)
Delirium in Shanghan belongs to the Shaoyin channel; Zhang Zhongjing’s attribution to the Yangming channel is incorrect. Internal heat in the Yangming channel must lead to mania; since there is only delirium here, it belongs to the Shaoyin channel. (Zhang Zhongjing’s references to spiritual emptiness did not exclude Shaoyin involvement.) Urgent moxibustion on Guanyuan (CV4) for 300 moxa cones is required. If symptoms persist after moxibustion, death ensues.
If epistaxis does not exceed one or two small cups, it indicates that qi and blood are harmonizing, and recovery will occur without sweating. If bleeding reaches the volume of a sheng or dou, it signifies the collapse of true qi. Needle Guanyuan (CV4) to a depth of three cun, retain the needle for twenty breaths, and the bleeding will stop immediately. Follow with moxibustion on Guanyuan (CV4) for 200 cones and administration of Jin Ye Dan (Golden Fluid Pill). Otherwise, xu lao (deficiency consumption) and zhong man (abdominal fullness) may develop. (One must decide whether to release the exterior, clear heat, warm the interior, or tonify, treating according to a careful assessment of the syndrome to avoid errors.)
After recovery from Shanghan, fever recurs due to improper diet, daily activities, or overexertion. Symptoms include headache, body heat, irritability, abdominal pain, and a floating and tight pulse. This is known as Lao Fu (recurrence due to labor). Administer Ping Wei San (Peaceful Stomach Powder) and Fen Qi Wan (Qi-Separating Pill); recovery occurs with sweating. If taken three or four times without effect, it indicates severe deficiency of primordial qi. Moxibustion on Zhongwan (CV12) for 50 cones is indicated. (For Lao Fu, Zhang Zhongjing provided several formulas; their use requires careful consideration. First, one must ascertain the presence or absence of pathogenic factors and distinguish the degree of cold and heat to ensure correct treatment.)
