王叔和曰∶问曰∶妇人病如癫疾，郁冒，一日二十余发。师脉之，反言带下，皆如师言，其脉何类，何以
别之？师曰∶寸口脉濡而紧，濡则阳气微，紧则荣中寒。阳微，卫气虚，血竭凝寒，阴阳不和，邪气合于荣卫。
疾起年少时，经来以合房室，移时过度，精感命门开，经下血则虚，百脉皆张，中极感阳动，微风激成寒，因
虚合于荣卫。冷积于丹田，发动上冲，奔在胸膈，津液掩口，涎唾溢出胃，状如厥气冲，髀里热。粗医名为癫，
灸之，因大剧。
陈藏器曰∶一犯月水行房，精血相射，入于任脉，留于胞中，以致小腹结病，病如伏梁，水溺频涩，是名
积精。妇人闺房有三禁，此其一也。
《原病集》曰∶有妇人月经来时，交合阴阳，致伤血络，多成经漏淋漓，俗云血沙淋是也。治常调和血气，
使脏腑和平，经自止矣。
慎斋按∶以上三条，序妇人经行而交合，致有癫冒、伏梁、经漏之三证也。凡妇人经行，血海净尽而交合，
则精凝血聚，可以成胎。若经适来，而不禁房室，则败血不出，积精相射，致有诸证。此人之最易犯者，医者
审察病机，不可不晓。
慎斋按∶以上自褚侍中“合之非时”一论至此，其条序分十七段，皆属经候不调之故，以下始序治调经之
大法。
李氏曰∶妇人月水循环，纤 不作而有子。若兼潮热腹痛，重则咳嗽汗呕，或泻，有潮汗，则血愈消耗。
有汗咳呕，则气从上行，泻则津偏于后，痛则积结于中，是以必先去病，而后可以滋血调经。就中潮热疼痛，
尤为妇人常病。盖血滞积入骨髓，便为骨蒸。血滞积瘀，与日生新血相抟，则为疼痛。血枯不能滋养百骸，则
蒸热于内。血枯，胞络火盛，或挟痰气食积，寒冷则为疼痛。凡此诸病，皆阻经候不调，必先去其病，而后
可以调经也。
王叔和说：有人问：妇人患病症状像癫狂病，伴有头昏目眩、意识模糊（郁冒），一天发作二十多次。医生诊脉后，反而说是带下病，结果都符合医生的判断，这种病的脉象是什么样的？如何辨别它？医生说：寸口脉象濡软而紧，濡脉表示阳气微弱，紧脉表示营血中有寒邪。阳气微弱导致卫气虚弱，血液枯竭凝滞寒冷，阴阳失调，邪气与营卫之气相合。此病起于年少时，月经期间行房事，时间过长过度耗损，精气感召命门穴开启，经血下行导致身体虚损，全身血脉扩张，中极穴感受阳动之邪，微风激发形成寒邪，因虚而与荣卫之气相合。寒气积聚于丹田，发动上冲，奔突于胸膈之间，津液覆盖口腔，涎唾从胃中溢出，症状类似厥气上冲，大腿内侧发热。粗劣的医生将其诊断为癫病，施以艾灸治疗，导致病情加重。
陈藏器说：如果在月经期间行房事，精血相互冲击，进入任脉，滞留于胞宫，导致小腹结块病症，病状如同伏梁病（腹部积块），小便频繁且涩痛，这叫做“积精”。这是妇人在闺房生活中三条禁忌之一。
《原病集》说：有妇人在月经来潮时交合阴阳，导致损伤血络，多形成经血淋漓不尽的症状，俗称“血沙淋”。治疗通常调和气血，使脏腑功能平和，经血自然停止。
慎斋按语：以上三条，叙述了妇人在经期行房事，导致出现癫狂眩晕、伏梁积块、经血淋漓这三种证候。凡是妇女在经期，如果血海排空干净后再行房事，则精血凝结聚拢，可以受孕成胎。如果月经刚来，而不禁止房事，则败血不能排出，积精与败血相互冲击，导致各种病症。这是人们最容易犯的错误，医生审察病机，不可不明了。
慎斋按语：以上从褚侍中的“不合时宜交合”这一论述至此，条理顺序分为十七段，都属于月经不调的原因，以下才开始叙述调理月经的大法。
李氏说：妇女月经循环通畅，如果没有异常症状就可以怀孕生子。如果兼有潮热腹痛，严重的出现咳嗽、出汗、呕吐，或者腹泻，有潮热出汗，则血液更加消耗。如果有汗出、咳嗽、呕吐，则气机上逆；腹泻则津液偏走后方；疼痛则积结于中部。因此必须先去除疾病，然后才能滋养血液、调理月经。其中潮热疼痛，尤为妇女常见疾病。因为血液停滞积聚深入骨髓，就成为骨蒸劳热。血液停滞瘀阻，与每天生成的新血相搏结，就产生疼痛。血液枯竭不能滋养全身骨骼，则在体内产生蒸热。血液枯竭，胞络火盛，或者夹杂痰气、食积，遇寒冷则产生疼痛。所有这些疾病，都会阻碍月经调畅，必须先去除其病，然后才可以调理月经。
Wang Shuhe said: A question was asked: A woman suffers from a disease resembling mania (dian疾), accompanied by dizziness and faintness (yumao), occurring more than twenty times a day. The physician palpated the pulse and instead diagnosed it as leukorrhea (daixia). All symptoms matched the physician's diagnosis. What is the characteristic of this pulse, and how can it be distinguished? The physician replied: The cunkou (inch position) pulse is soft and tight (ru er jin). A soft pulse indicates deficient yang qi; a tight pulse indicates cold in the ying (nutrient) blood. Deficient yang leads to weak wei (defensive) qi; blood exhaustion with coagulation and cold causes disharmony between yin and yang, allowing pathogenic factors to combine with ying and wei qi. This disease originated in youth when sexual intercourse occurred during menstruation. Prolonged and excessive activity stimulated the Mingmen gate, causing blood loss through menstruation and bodily deficiency, while all vessels expanded. The Zhongji point felt the movement of yang, and slight wind triggered cold due to deficiency, combining with ying and wei qi. Cold accumulated in the Dantian, surged upward, rushing into the chest and diaphragm, covering the mouth with fluids, with saliva overflowing from the stomach. The condition resembled counterflow qi (jueqi) surging, with heat in the thighs. Crude physicians misdiagnosed it as mania and applied moxibustion, causing the condition to worsen significantly.
Chen Cangqi said: If sexual intercourse occurs during menstruation, essence and blood collide, entering the Ren Mai (Conception Vessel) and remaining in the uterus (baozhong), resulting in abdominal masses. The condition resembles Fuliang (a type of abdominal mass), with frequent and difficult urination. This is called "Jijing" (accumulated essence). This is one of the three prohibitions for women regarding sexual conduct.
The Yuanbing Ji states: When a woman engages in sexual intercourse during her menstrual period, she may injure the blood collaterals, often leading to prolonged dripping of menstrual blood, commonly known as "Xuesha Lin" (blood sand strangury). Treatment usually involves harmonizing qi and blood so that the zang-fu organs function peacefully, and menstruation will stop naturally.
Shenzhou commented: The above three passages describe three conditions caused by sexual intercourse during menstruation: mania and dizziness, Fuliang masses, and prolonged menstrual bleeding. Generally, if a woman has sexual intercourse after her menstrual blood has completely cleared, the essence and blood can condense and gather to conceive a fetus. However, if intercourse occurs while menstruation is just starting without abstinence, retained blood cannot exit, and accumulated essence collides with it, causing various disorders. This is an error people easily make; physicians must thoroughly understand these pathological mechanisms.
Shenzhou commented: From the discussion by Attendant Physician Chu on "intercourse at improper times" up to this point, the content is divided into seventeen sections, all attributing irregular menstruation to specific causes. The following section begins to outline the general principles for regulating menstruation.
Li Shi said: Women's menstrual cycles flow smoothly; if there are no abnormal symptoms, pregnancy can occur. However, if accompanied by tidal fever and abdominal pain, or severe cases involving coughing, sweating, vomiting, or diarrhea, and tidal sweating, the blood becomes further depleted. Sweating, coughing, and vomiting cause qi to ascend; diarrhea causes body fluids to drain posteriorly; pain causes accumulation in the center. Therefore, diseases must be removed first before nourishing blood and regulating menstruation. Among these, tidal fever and pain are particularly common ailments for women. When blood stagnation accumulates deeply into the bone marrow, it becomes bone-steaming consumption. Blood stasis and瘀 (stasis) contend with newly generated daily blood, causing pain. Blood dryness fails to nourish the bones, causing internal steaming heat. Blood dryness leads to excessive fire in the uterine collaterals, or combines with phlegm, qi stagnation, or food retention; exposure to cold causes pain. All these diseases obstruct regular menstruation; one must eliminate the disease first before regulating menstruation.
