痛而发黄为中湿，痛不得转侧为风湿。《活人》又以身痛脉沉为中湿，脉浮为风湿，亦通。治法见太阳病体
痛门。
妇人中风，发热恶寒，经水适来，得之七八日，热除而脉迟，身凉，胸胁下满，如结胸状，谵语者，此为
热入血室也。当刺期门，随其实而泻之。（东垣云∶妄见妄闻，夜梦亡人，皆肝木火盛而为邪也，刺期门。与此义同。）
许学士云∶有妇人患热入血室证，医者不识，用补血调气药，延养数日，遂成血结胸。或劝用前药。予曰∶
小柴胡已迟，不可行也。无已，则有一焉，刺期门穴斯可矣。予不能针，请善针者治之，如言而愈。或问曰∶
热入血室，何谓而成结胸也？予曰∶邪气传入经络，与正气相搏，上下流行，或遇经水适来适断，邪气乘虚而
入血室，血为邪迫，上入肝经，肝受邪则谵语而见鬼，复入膻中，则血结于胸也。何以言之？妇人平居，水当
养于木，血当善于肝。方未受孕，则下行之以为月水；既妊，则中蓄之以养胎；及已产，则上壅之以为乳，皆
此血也。今邪气蓄血，并归肝经，聚于膻中，结于乳下，故手触之则痛，非汤剂可及，故当刺期门也。
妇人伤寒发热，经水适来，昼日明了，夜则谵语，如见鬼状者，此为热入血室，无犯胃气及上二焦，
必自愈。（《活人》云∶小柴胡和之。犯胃气谓下之，犯上二焦谓发汗也。）
〔《衍》〕有一妇人，温病已十二日，诊之，其脉六七至而涩，寸稍大，尺稍小，发寒热，颊赤口干，不
了了，耳聋。问之，病数日经水乃行，此属少阳热入血室也。若治不对病，则必死。乃按其证与小柴胡汤，服
之二日，又与小柴胡汤加桂、干姜一日，寒热遂止。又云∶我脐下急痛。又与抵当丸微利，脐下痛痊，身渐凉，
脉渐匀，尚不了了。仍复与小柴胡汤。次日又云∶我但胸中热躁，口鼻干。又少与调胃承气汤，不得利。次日
又云∶心下痛。又与大陷胸丸半服，利三行。次日，虚烦不乐，时亦有所见，时复狂言。虽知其尚有燥屎，以
其极虚，不敢攻之。遂与竹叶汤，去其烦热。其夜大便自通，至晓两次，中有燥屎数枚，而狂言虚烦尽解。但
咳嗽唾，此肺虚也，恐乘虚而成肺痿。遂与小柴胡去人参、大枣、生姜，加干姜、五味子汤。一日咳减，二日
而病悉愈。以上皆用张仲景方。
妇人中风七八日，续得寒热，发作有时，经水适断者，此为热入血室，其血必结，故如疟状，发作
有时。小柴胡汤主之。
Pain accompanied by jaundice indicates dampness obstructing the middle (Zhong Shi); pain with inability to turn or lie on one's side indicates wind-dampness. The *Liu Ren Shu* (Book of Vitality) further states that body pain with a deep pulse indicates dampness obstructing the middle, while body pain with a floating pulse indicates wind-dampness; this interpretation is also valid. For treatment methods, refer to the section on "Body Pain in Taiyang Disease" (Taiyang Bing Ti Tong).
Sweating characterizes Soft Spasm (Rou Jing), while absence of sweating characterizes Stiff Spasm (Gang Jing). (For treatment methods, refer to the section on "Soft Spasm".)
When a woman contracts Wind Pathogen, presenting with fever and aversion to cold, and her menses happen to commence, after seven or eight days, if the heat subsides and the pulse becomes slow, the body feels cool, there is fullness and distension below the chest and hypochondrium resembling Chest Binding (Jie Xiong), and she speaks deliriously, this is called Heat Entering the Blood Chamber (Re Ru Xue Shi). One should puncture Qimen (LR14) and apply the reducing method according to the excess condition. (Li Dongyuan stated: Hallucinations of seeing and hearing things, and dreaming of deceased persons at night, are all caused by excessive Liver Wood Fire generating pathogenic factors; puncturing Qimen applies here. This shares the same principle.) Xu Xueshi said: A woman suffered from Heat Entering the Blood Chamber. The physician failed to recognize the condition and administered blood-nourishing and qi-regulating herbs. After several days of neglectful care, it developed into Blood Chest Binding (Xue Jie Xiong). Someone advised using the aforementioned prescription. I said: Using Xiao Chai Hu Tang (Minor Bupleurum Decoction) is now too late and cannot be applied. If forced to choose another method, puncturing the Qimen acupoint would suffice. I am not skilled in acupuncture, so I requested an expert to treat her. Following this advice, she recovered. Someone asked: Why does Heat Entering the Blood Chamber result in Chest Binding? I said: The pathogenic factor enters the meridians and contends with healthy Qi, circulating up and down. If it coincides with the onset or cessation of menstruation, the pathogen enters the Blood Chamber due to deficiency. The blood is forced by the pathogen to ascend into the Liver Meridian. When the Liver is affected by the pathogen, delirium occurs and hallucinations of ghosts appear. If the pathogen re-enters the Danzhong (Chest Center), blood coagulates in the chest. Why do I say this? In women, water nourishes Wood, and blood is managed by the Liver. Before conception, blood descends to become menstrual flow; during pregnancy, it accumulates centrally to nourish the fetus; after childbirth, it ascends to form milk. All these are the same blood. Now, pathogenic factors accumulate blood, directing it together into the Liver Meridian, gathering at Danzhong, and knotting below the breasts. Thus, palpation causes pain. This location is beyond the reach of herbal decoctions, hence puncturing Qimen is required.
When a woman suffers from Cold Damage with fever, and her menses happen to commence, if she is lucid during the day but delirious at night, appearing as if seeing ghosts, this is Heat Entering the Blood Chamber. Do not damage the Stomach Qi or the Upper and Middle Jiao; the disease will resolve spontaneously. (*Liu Ren Shu* states: Harmonize it with Xiao Chai Hu Tang (Minor Bupleurum Decoction). Damaging Stomach Qi refers to purgation; damaging the Upper and Middle Jiao refers to diaphoresis.)
[From *Yan Yi*] There was a woman who had suffered from Warm Disease for twelve days. Her pulse was rapid (six to seven beats per breath) and choppy; the Cun position was slightly large, and the Chi position slightly small. She presented with alternating chills and fever, flushed cheeks, dry mouth, unclear consciousness, and deafness. Upon inquiry, it was found that her menses began several days into the illness. This belongs to Shaoyang Heat Entering the Blood Chamber. If treated incorrectly, death is certain. Based on the syndrome, Xiao Chai Hu Tang (Minor Bupleurum Decoction) was administered. After two days, Xiao Chai Hu Tang (Minor Bupleurum Decoction) with added Guizhi (Cinnamon Twig) and Ganjiang (Dried Ginger) was given for one day, and the chills and fever ceased. The patient then complained of urgency and pain below the umbilicus. Didang Wan (Didang Pill) was given to induce mild purgation. The abdominal pain resolved, the body cooled gradually, and the pulse became even, though consciousness remained unclear. Xiao Chai Hu Tang (Minor Bupleurum Decoction) was administered again. The next day, she reported only chest heat and restlessness, with dry mouth and nose. A small dose of Tiaowei Chengqi Tang (Regulate the Stomach and Direct Downward Decoction) was given, but no stool was passed. The next day, she complained of pain in the epigastrium. Half a dose of Daxianxiong Wan (Major Draining the Chest Pill) was given, resulting in three bowel movements. The next day, she felt weak, irritable, and occasionally hallucinated or spoke madly. Although dry feces were suspected, due to her extreme deficiency, aggressive purgation was avoided. Zhuye Tang (Bamboo Leaf Decoction) was given to clear residual heat and irritability. That night, stool passed naturally. By morning, two bowel movements occurred, passing several pieces of dry feces. Delirium and irritability completely resolved. However, she coughed and expectorated phlegm, indicating Lung Qi deficiency, with a risk of developing Lung萎 (Fei Wei/Lung Atrophy) due to deficiency. Thus, Xiao Chai Hu Tang (Minor Bupleurum Decoction) was modified by removing Renshen (Ginseng), Dazao (Jujube), and Shengjiang (Fresh Ginger), and adding Ganjiang (Dried Ginger) and Wuweizi (Schisandra Berry). Cough decreased after one day, and the disease was fully cured after two days. All the above cases utilized formulas from Zhang Zhongjing.
When a woman contracts Wind Pathogen for seven or eight days, subsequently developing alternating chills and fever with regular timing, and her menses have just ceased, this is Heat Entering the Blood Chamber. The blood must be knotted, hence the symptoms resemble malaria with regular paroxysms. Xiao Chai Hu Tang (Minor Bupleurum Decoction) is the primary treatment.
