思虑太重，则成气消；
不得早起，不得劳心费力，反此则病必复。
夫伤寒感冒，但有轻重之分，重者为伤，轻者为感。必须问症以察于外，切脉以审于内，
尤当辨其阴阳，观其传变。一日至三日病在皮肤者为表，宜投药汗之，以驱散其寒邪。有汗
不得服麻黄，无汗不得服桂枝。四日五日之间病在胸膈，痰气紧满枝上，宜投药以吐之。六
日七日之间其病入腹，脏腑结燥，狂言潮热，宜投药以下之。又有初得病即胸腹闷痛，胃气
喘息，则又不可拘以日数，即宜下之。又有六七日尚或头痛恶寒，项上有汗，小便清利，乃
表症未除，仍宜汗之。若应汗而反下，则热蓄于里必致发狂而或结胸；若应下而反汗，则津
竭体虚必至亡阳而谵语；若应吐而温补，则毒瓦斯郁于内心发而为斑，色如锦纹者生，色黑者
难疗。其中变易非止一端，略举其概，以备仓卒调理。伤寒不可不谨，临症用药切宜详慎。

思虑过度，会导致气机耗散；
不能早起，不能劳心费力，如果违背这些原则，疾病必定复发。
至于伤寒感冒，只有轻重的区别，重者称为“伤”，轻者称为“感”。必须通过问诊来观察外在症状，通过切脉来审察内在情况，
尤其应当辨别其阴阳属性，观察病邪的传变过程。发病一日至三日，病邪在皮肤表层属于表证，适宜用药发汗，以驱散寒邪。有汗出的患者不得服用麻黄，无汗出的患者不得服用桂枝。第四日至第五日之间，病邪在胸膈部位，痰气壅盛、胸部胀满，适宜用药催吐。第六日至第七日之间，病邪入腹，脏腑燥结，出现胡言乱语、定时发热等症状，适宜用药攻下。又有初得病即出现胸腹闷痛、胃气上逆喘息的情况，则又不必拘泥于发病天数，应立即使用攻下法。又有六七日仍然头痛恶寒，项部出汗，小便清长通畅的，这是表证未除，仍宜使用发汗法。如果应当发汗却反而使用攻下法，则热邪蓄积于体内，必然导致发狂或形成结胸证；如果应当攻下却反而使用发汗法，则津液枯竭、身体虚弱，必然导致亡阳而出现谵语；如果应当催吐却使用温补法，则毒瓦斯郁结于内心而发为斑疹，颜色如锦纹者可生，颜色黑者难治。其中的病情变化不止一端，略举其大概，以备仓促间调理之用。治疗伤寒不可不谨慎，临症用药务必详细审慎。

Excessive thinking leads to the consumption of Qi;
One should not stay up late, nor engage in mental or physical labor; violating these principles will inevitably cause the disease to relapse.
Regarding Taiyang disease (diseases caused by external pathogenic factors affecting the Taiyang channel) and common colds, there are only distinctions of severity: severe cases are termed "Shang" (injury), while mild cases are termed "Gan" (sensation). One must inquire about symptoms to observe external signs and palpate the pulse to examine internal conditions,
especially distinguishing between Yin and Yang and observing the transmission and transformation of the disease. From the first to the third day, if the pathogen is in the skin and surface, it is a Exterior Syndrome (a syndrome where the pathogen is located on the exterior of the body), and it is appropriate to administer diaphoretic herbs to disperse the Cold Evil (pathogenic cold). Patients with sweating should not take Ephedra Decoction (Mahuang Tang); patients without sweating should not take Cinnamon Twig Decoction (Guizhi Tang). Between the fourth and fifth days, if the pathogen is in the chest and diaphragm, with phlegm and Qi stagnation causing tightness and fullness, it is appropriate to administer emetic herbs. Between the sixth and seventh days, if the pathogen enters the abdomen, causing dryness and knotting in the Zang-Fu organs, accompanied by delirious speech and tidal fever, it is appropriate to administer purgative herbs. In cases where chest and abdominal stuffiness and pain occur immediately upon contracting the disease, along with stomach Qi rebellion and wheezing, one should not be bound by the number of days but should immediately use purgation. In cases where headache, aversion to cold, sweating on the nape, and clear, free urination persist after six or seven days, this indicates that the Exterior Syndrome has not been resolved, and diaphoresis is still indicated. If diaphoresis is indicated but purgation is used instead, heat will accumulate internally, likely leading to mania or Chest Binding Syndrome (Jie Xiong); if purgation is indicated but diaphoresis is used instead, fluid exhaustion and body deficiency will lead to Yang collapse and delirium; if emesis is indicated but warming tonification is used, toxic vapors will stagnate in the heart, manifesting as macules; those with colors like brocade may survive, while those with black colors are difficult to treat. The variations in condition are numerous; I have briefly outlined the general principles for emergency management. Treating Taiyang disease requires caution, and medication administration during clinical practice must be detailed and prudent.
