伤寒病经过五六天，出现头部出汗、轻微怕冷、手脚发凉、胃脘部胀满、不想吃东西、大便干硬、脉象细的情况，这叫做“阳微结”（阳气轻微郁结）。一定是有表证又有里证。脉象沉也说明病在里。出汗是因为阳气轻微郁结。
假如是纯粹的阴寒凝结，就不会再有外面的表证，所有症状都进入体内，这就是病完全在里。现在既有表证，说明病一半在表、一半在里。脉象虽然沉紧，但不能诊断为少阴病（少阴经受邪所致的病证）。之所以这样判断，是因为少阴病通常不会有汗，现在只有头部出汗，所以知道这不是少阴病。
可以给予小柴胡汤（和解少阳的代表方剂）。如果服药后病情仍然没有完全缓解，通过排便就能痊愈。
伤寒病经过五六天，出现头部出汗、轻微怕冷、手脚发凉、胃脘部胀满、不想吃东西（默默不欲饮食）、大便干硬、脉象细（包含沉紧之象），这是阳明经的轻微郁结。
因为少阳和阳明两经的气机郁滞逼迫，结聚在胃口处，所以胃脘部胀满；经络中的热邪熏蒸，所以头部出汗。一定伴有少阳的表证，如出汗、怕冷、四肢发冷、心下胀满等；又伴有阳明的里证，如大便干硬等。大概是因为少阳与阳明合病，戊土（脾/胃之气）不能克制甲木（胆/肝之气），病势必然传入阳明的胃腑，所以肯定有里证。脉象沉主病在里；出汗是阳经的轻微郁结。假如纯粹是阴分的郁结（这里的“阳”指少阳经，“阴”指阳明腑），就一定不会再有像出汗、怕冷这样的外证，应当全部表现为里证。既然有外证，这说明病一半在里、一半在表。
其脉象虽然沉紧，也不能诊断为少阴病。原因所在，是少阴病不应该有汗，现在只有头部出汗，所以知道这不是少阴病，而是实为少阳病。这是大柴胡证的范畴，先给予小柴胡汤以解除少阳经的邪气。如果服用后仍然感觉不适，再用承气汤类方剂泄除阳明腑的邪气，通过排便就能痊愈。
太阳病超过病程阶段十余日，心中感到恶心欲吐且胸中疼痛，大便反而稀溏，腹部轻微胀满，情绪郁郁不乐且轻微烦躁。如果在之前此时曾经用过剧烈的催吐或泻下法，可以使用调胃承气汤（方剂见阳明篇第二十节）。如果不是这种情况，则不可使用。如果只是想要呕吐、胸中痛、大便稀溏，这不是柴胡证。因为有呕吐的症状，所以知道是之前剧烈吐下所致。
太阳病超过病程阶段十余日，本不应在少阳经，但出现心中恶心欲吐、胸中疼痛、大便反而稀溏、腹部轻微胀满、情绪郁郁不乐且轻微烦躁，又似乎像少阳柴胡证（这是因为胃土受到胆木的逼迫，出现这样的见证）。怎么会有少阳证持续这么久的情况呢？如果在此之前自己曾经过度使用吐法或下法，那么这就是少阳病传变为阳明病。此时少阳的经证轻微，而阳明的腑证已经形成，可以使用调胃承气汤，无需使用柴胡剂。因为少阳病传变至阳明，经气逼迫腑气导致郁结，通常会出现呕吐和下利的症状，即大柴胡证。当吐下症状严重时，正是少阳与阳明经腑同时受病的时刻，所以大柴胡汤是柴胡与承气并用，双解经腑之邪。现在已经过度吐下在先，仅剩下想吐和大便稀溏，这只是少阳病的余波，所以不使用柴胡剂而使用承气剂。如果不是由自己过度吐下引起的，那就是太阴病（脾阳虚衰所致的病证），不可使用承气汤。之所以知道是由之前的吐下引起，是因为今天出现的想吐和大便稀溏，显示少阳的余波仍在。
Taiyang disease (disease of the Taiyang channel) after five or six days presents with sweating on the head, slight aversion to cold, cold hands and feet, fullness in the epigastrium, anorexia, hard stools, and a fine pulse. This is termed "Yang Wei Jie" (mild constriction of Yang Qi). There must be both exterior and interior syndromes. A deep pulse indicates the pathology is interior. Sweating occurs due to mild Yang constriction.
If it were purely Yin constriction, there would be no exterior symptoms remaining; all manifestations would be interior. This would indicate the disease is entirely interior. Since there are now exterior symptoms, it indicates the disease is half-exterior and half-interior. Although the pulse is deep and tight, it cannot be diagnosed as Shaoyin disease (disease of the Shaoyin channel). The reason is that Shaoyin disease typically does not present with sweating. Since only the head is sweating, we know this is not Shaoyin disease.
Xiao Chai Hu Tang (Minor Bupleurum Decoction) may be administered. If the patient remains uncomfortable after taking it, recovery will occur upon defecation.
Taiyang disease after five or six days presents with sweating on the head, slight aversion to cold, cold hands and feet, fullness in the epigastrium, anorexia (silent desire for no food), hard stools, and a fine pulse (encompassing deep and tight qualities). This represents mild constriction in the Yangming channel.
Because the Qi stagnation of both the Shaoyang and Yangming channels forces and knots at the stomach opening, there is epigastric distension. Heat steaming from the channels causes sweating on the head. There must be Shaoyang exterior symptoms, such as sweating, aversion to cold, cold limbs, and epigastric fullness; and Yangming interior symptoms, such as hard stools. Generally, when Shaoyang and Yangming diseases combine, Wu Earth (Spleen/Stomach Qi) fails to control Jia Wood (Gallbladder/Liver Qi), so the pathology inevitably transmits to the Yangming Stomach Fu organ, ensuring interior symptoms. A deep pulse indicates interior pathology; sweating indicates mild Yang channel constriction. If it were purely Yin compartment constriction (here, "Yang" refers to the Shaoyang channel, and "Yin" refers to the Yangming Fu organ), there would certainly be no exterior symptoms like sweating or aversion to cold; all would manifest as interior signs. Since exterior symptoms exist, it indicates the disease is half-interior and half-exterior.
Although the pulse is deep and tight, it cannot be diagnosed as Shaoyin disease. The reason is that Shaoyin disease should not have sweating. Since only the head is sweating, we know this is not Shaoyin but actually Shaoyang disease. This falls under the category of Da Chai Hu Tang (Major Bupleurum Decoction) syndrome. First, administer Xiao Chai Hu Tang to resolve the Shaoyang channel pathogen. If discomfort persists after administration, use Cheng Qi Tang (Order the Qi Decoction) variants to drain the Yangming Fu pathogen, and recovery will occur upon defecation.
Taiyang disease exceeding its stage by more than ten days presents with nausea/desire to vomit, chest pain, loose stools, mild abdominal fullness, depression, and slight irritability. If the patient had previously undergone extreme emesis or purgation at that time, Tiao Wei Cheng Qi Tang (Regulate the Stomach Order the Qi Decoction) [Formula found in Yangming Chapter 20] may be used. If not, it should not be used. Symptoms of mere desire to vomit, chest pain, and loose stools do not constitute a Chai Hu syndrome. The presence of vomiting indicates it was caused by previous extreme emesis or purgation.
Taiyang disease exceeding its stage by more than ten days should no longer be in the Shaoyang phase. However, symptoms of nausea/desire to vomit, chest pain, loose stools, mild abdominal fullness, depression, and slight irritability resemble Shaoyang Chai Hu syndrome (this presentation results from Stomach Earth being pressured by Gallbladder Wood). How can a Shaoyang syndrome persist for so long? If the patient had previously undergone extreme emesis or purgation, this represents Shaoyang transmitting to Yangming. The Shaoyang channel syndrome is mild, while the Yangming Fu syndrome has formed. Tiao Wei Cheng Qi Tang may be used without Chai Hu agents. When Shaoyang transmits to Yangming, channel pressure on Fu organs causes constriction, typically presenting with vomiting and diarrhea, i.e., Da Chai Hu Tang syndrome. When vomiting and purgation are severe, it is precisely the time when both Shaoyang and Yangming channels and Fu organs are affected; thus, Da Chai Hu Tang combines Chai Hu and Cheng Qi agents to simultaneously resolve channel and Fu pathogens. Here, since extreme emesis/purgation occurred first, only residual desire to vomit and loose stools remain, representing residual Shaoyang waves. Therefore, Chai Hu agents are not used, but Cheng Qi agents are. If these symptoms did not arise from self-induced extreme emesis/purgation, it would be a Taiyin syndrome (disease of the Taiyin channel characterized by Spleen Yang deficiency), and Cheng Qi Tang should not be used. We know it stems from prior emesis/purgation because today's desire to vomit and loose stools show that Shaoyang residual waves are still present.
