问曰∶少腹满，何以是传经厥阴证？答曰∶胸膈以上，乃清阳之分，为少阳之分野；胸
膈以下，少腹以上，乃清浊交界之所，为太阴之分野；当脐者，少阴之分野；少腹者，厥阴
之分野。伤寒传至厥阴，少腹胀满，乃浊阴凝聚，实为有物矣，宜急下之。又问曰∶瘀血与
溺涩，亦少腹满，何也？答曰∶瘀血者，太阳膀胱经蓄血也；溺涩者，太阳膀胱经蓄水也。
膀胱系于脐下，故少腹满也。但蓄血证，少腹满，小便自利，大便黑色；溺涩证，小腹满，
小便不利，大便如常。若邪传厥阴，则大便闭结，小便短赤，是为燥粪证也。且厥阴必有烦
满囊缩，厥逆消渴诸症，与太阳膀胱经证，迥然不同也。
问曰∶舌蜷囊缩，何以是传经厥阴证？答曰∶肝主周身之筋，热邪内灼，则津液枯，
不能荣养于筋，故舌蜷而囊缩，宜急下之。又问曰∶直中证，亦舌蜷囊缩何也？答曰
∶直中于寒，阳气衰微而敛缩，此冬令万物闭藏之象，今内热消烁，此夏令津液干枯之象。
然直中证，脉必沉迟，或见下利清谷，口鼻气冷诸寒证。邪传厥阴，必烦满消渴之极，或唇
焦口燥，身如枯柴，形情大不相同。且直中证，舌虽短缩而润泽；邪传厥阴，则舌敛束如荔
枝，必然焦燥毫无津液。又问曰∶妇人之诊如何？答曰∶妇人乳缩，男人囊缩，先验其舌，
已自明白，不待细问矣。是以伤寒验舌之法不可不讲。
问：少腹部胀满，为什么说是邪气传入厥阴经的证候？答：胸膈以上，是清阳之气分布的区域，属于少阳经的管辖范围；胸膈以下、少腹以上，是清气与浊气交界的地方，属于太阴经的管辖范围；肚脐周围，是少阴经的管辖范围；少腹部，是厥阴经的管辖范围。伤寒病邪传至厥阴经时，出现少腹胀满，这是浊阴之气凝聚所致，体内确实有实邪积滞，应当紧急使用攻下法治疗。又问：瘀血阻滞和排尿不畅（淋证），也会导致少腹胀满，这是怎么回事？答：瘀血阻滞，是太阳膀胱经受邪后形成的蓄血证；排尿不畅，是太阳膀胱经受邪后形成的蓄水证。膀胱位于脐下，所以会出现少腹胀满。但是，蓄血证的特点是少腹胀满，小便通畅正常，大便颜色发黑；蓄水证（溺涩）的特点是少腹胀满，小便排出不利，大便如常。如果邪气传入厥阴经，则会出现大便闭结不通，小便短少色赤，这属于燥屎内结的证候。而且，厥阴病必然伴有心中烦闷胀满、阴囊收缩、四肢厥冷、口渴多饮等症状，这与太阳膀胱经的证候截然不同。
问：舌头卷缩、阴囊收缩，为什么说是邪气传入厥阴经的证候？答：肝主管全身筋脉，热邪在体内灼烧，导致津液枯竭，无法滋养筋脉，所以出现舌头卷缩和阴囊收缩的症状，应当紧急使用攻下法治疗。又问：寒邪直中脏腑（直中证），也会出现舌头卷缩、阴囊收缩，这是怎么回事？答：寒邪直中，是因为阳气衰微而收敛收缩，这是冬季万物闭藏的象；现在体内热邪消烁津液，这是夏季津液干枯的象。然而，直中寒证的脉象必定沉迟，或者出现下利清谷（腹泻排出未消化的食物）、口鼻气息寒冷等寒证表现。邪气传入厥阴经，必定出现极度烦闷胀满和口渴，或者嘴唇焦裂、口干舌燥，身体像枯柴一样消瘦，病情表现大不相同。而且，直中寒证，舌头虽然短缩但表面润泽；邪气传入厥阴经，则舌头紧缩如荔枝壳状，必然焦干燥裂，完全没有津液。又问：对妇女的诊断有什么特点？答：妇女表现为乳房收缩，男子表现为阴囊收缩，先观察舌头，情况自然明白，不需要详细询问了。因此，伤寒病通过观察舌头来诊断的方法不可不研究讲究。
Question: Why is abdominal fullness considered a syndrome of the Jueyin meridian transmission? Answer: The area above the chest and diaphragm is the domain of clear Yang, belonging to the Shaoyang meridian; the area between the chest/diaphragm and the lower abdomen is the junction of clear and turbid Qi, belonging to the Taiyin meridian; the area around the navel is the domain of the Shaoyin meridian; the lower abdomen is the domain of the Jueyin meridian. When cold damage (Shanghan) transmits to the Jueyin meridian, lower abdominal distension and fullness occur due to the accumulation of turbid Yin, representing an excess pathogen that requires urgent purgation. Another question arises: Blood stasis and dysuria also cause lower abdominal fullness; why is this so? Answer: Blood stasis refers to blood retention in the Taiyang Bladder meridian; dysuria refers to water retention in the Taiyang Bladder meridian. Since the bladder is located below the navel, lower abdominal fullness occurs. However, in blood retention syndrome, there is lower abdominal fullness with normal urination and black stools; in water retention syndrome (dysuria), there is lower abdominal fullness with difficult urination and normal stools. If the pathogen transmits to the Jueyin meridian, there will be constipation and scanty, dark urine, which constitutes a dry feces syndrome. Furthermore, Jueyin disease must present with vexation and fullness, retraction of the testicles, cold extremities, and excessive thirst, which are distinctly different from Taiyang Bladder meridian syndromes.
Question: Why are tongue curling and testicular retraction considered signs of Jueyin meridian transmission? Answer: The Liver governs the tendons of the whole body. When heat pathogens scorch internally, body fluids are depleted and cannot nourish the tendons, resulting in tongue curling and testicular retraction; this requires urgent purgation. Another question arises: Direct invasion by cold (Zhi Zhong) also causes tongue curling and testicular retraction; why is this so? Answer: Direct invasion by cold leads to contraction due to the decline and敛缩 (contraction) of Yang Qi, resembling the closure and storage of all things in winter. In contrast, internal heat consuming fluids resembles the drying up of fluids in summer. However, direct cold invasion presents with a deep and slow pulse, or symptoms such as diarrhea with undigested food and cold breath from the mouth and nose. Jueyin transmission involves extreme vexation, fullness, and thirst, or cracked lips, dry mouth, and a emaciated body like dried firewood, showing significant differences. Moreover, in direct cold invasion, although the tongue may be short and contracted, it remains moist; in Jueyin transmission, the tongue contracts tightly like a lychee shell, becoming necessarily scorched, dry, and devoid of fluids. Another question arises: How is diagnosis performed for women? Answer: Women present with breast retraction, while men present with testicular retraction. By examining the tongue first, the condition becomes clear without the need for detailed questioning. Therefore, the method of diagnosing Shanghan by observing the tongue must be studied carefully.
