《妇人良方》曰∶妇人带下，其名有五，因经行产后，风邪入胞门，传于脏腑而致之。若伤足厥阴肝经，
色如青泥。伤手少阴心经，色如红津。伤手太阴肺经，形如白涕。伤足厥阴脾经，黄如烂瓜。伤足少阴肾经，
黑如 血。人有带脉，横于腰间，如束带之状，病生于此，故名为带。
《金匮要略》曰∶妇人中风七八日，续来寒热，发作有时，经水适断，此为热入血室，其血必结，故使如
疟状，发作有时，小柴胡汤主之。
徐注曰∶妇人热入血室有四，热入血室必谵语，此则不谵语，但如疟状，谓伤寒男女皆有之，而妇人有独
异，故首曰妇人中风，即伤寒中所主桂枝汤之风证也。七八日，则表邪已解，复有寒热，故曰续来。然不长热，
故曰有时，问其经水，则已来而适断，明是余热未尽，乘虚入之，则余血必结，故寒热有时。然非太阳传入少
阳此，因结血之热致有此病，故曰使如症状。虽非传入少阳，而药仍用小柴胡者，盖血室之气，肝主之，肝
与胆为表里，胆因肝受邪，而病如疟。非他药所宜，故主和表里，谓上焦之气和，而骤结之血将自行也。若峻
攻之如抵当汤证，则犯少阳之禁矣。
按∶以上一条，是言经行未尽而适断，虽有结血，未为全实，小柴胡加当归、丹皮、生地以凉之。
《妇人良方》说：妇女带下病，其名称有五种，是因为在月经期间或产后，风邪侵入胞宫门户，传导至脏腑而导致的。如果损伤足厥阴肝经，白带颜色像青色的泥；损伤手少阴心经，白带颜色像红色的津液；损伤手太阴肺经，白带形状像白色的鼻涕；损伤足太阴脾经（注：原文误作足厥阴，实为足太阴），白带黄得像腐烂的瓜；损伤足少阴肾经，白带黑得像瘀血。人体有一条带脉，横向位于腰间，形状像束带一样，疾病发生在这里，所以称为带下病。
《金匮要略》说：妇女患中风症七八天后，持续出现忽冷忽热的症状，且发作有定时，此时月经恰好中断，这叫做热入血室证，血液必然凝结，所以症状像疟疾一样，发作有定时，用小柴胡汤主治。
徐忠可注解道：妇女热入血室证有四种情况，热入血室通常会出现谵语（神志不清、胡言乱语），但此条文中没有谵语，只是像疟疾一样忽冷忽热。这是因为伤寒男女都会得，但妇女有其独特之处，所以开头说“妇人中风”，指的就是伤寒中桂枝汤所主治的风邪表证。到了七八天，体表的邪气已经解除，却又出现忽冷忽热，所以说“续来”（再次出现）。然而发热时间不长，所以说“有时”。询问她的月经情况，则是已经来了却突然中断，明确是余热未尽，趁着正气虚弱侵入体内，那么残留的血液必然凝结，所以忽冷忽热发作有定时。但这并非太阳经传入少阳经所致，而是因为血液凝结产生的热导致此病，所以说症状像疟疾。虽然病邪不是传入少阳，但用药仍然使用小柴胡汤，大概是因为血室之气由肝所主，肝与胆互为表里，胆因肝受邪气影响，而表现出类似疟疾的症状。其他药物不适合这种情况，所以主张调和表里，意思是上焦之气调和后，骤然凝结的血液将会自行消散。如果用峻猛攻下的方法，就像抵当汤证那样，就会触犯少阳病的禁忌了。
按语：以上这一条，讲的是月经行将结束却突然中断的情况，虽然有血液凝结，但尚未完全形成实证，应在小柴胡汤基础上加入当归、丹皮、生地以起到凉血作用。
The *Furen Liangfang* (Good Prescriptions for Women) states: There are five types of leukorrhea in women, caused by wind-pathogen invading the uterine gate during menstruation or postpartum, and transmitting to the zang-fu organs. If the Foot-Jueyin Liver Meridian is injured, the discharge resembles green mud. If the Hand-Shaoyin Heart Meridian is injured, the discharge resembles red fluid. If the Hand-Taiyin Lung Meridian is injured, the discharge resembles white nasal mucus. If the Foot-Taiyin Spleen Meridian [Note: Original text erroneously says Foot-Jueyin] is injured, the discharge is yellow like rotting melon. If the Foot-Shaoyin Kidney Meridian is injured, the discharge is black like clotted blood. The human body possesses a Dai Mai (Belt Vessel), which crosses horizontally at the waist, resembling a sash. Since diseases arise here, it is named Dai Xia (Leukorrhea).
The *Jingui Yaolue* (Essential Prescriptions from the Golden Cabinet) states: In women suffering from Wind-Cold for seven to eight days, if chills and fever continue to occur intermittently with regular timing, and the menstrual flow happens to stop abruptly, this is termed Re Ru Xue Shi (Heat Entering the Blood Chamber). The blood must be congealed, causing symptoms resembling malaria with intermittent onset. Xiao Chai Hu Tang (Minor Bupleurum Decoction) should be administered as the primary treatment.
Xu Zhongke annotates: There are four variations of Heat Entering the Blood Chamber in women. Typically, Heat Entering the Blood Chamber presents with delirium, but this case lacks delirium, presenting only with malaria-like symptoms. This indicates that while Shang Han (Cold Damage) affects both men and women, women have unique pathophysiology. Thus, it begins with "Woman suffering from Wind," referring to the Wind-pattern treated by Guizhi Tang (Cinnamon Twig Decoction) in Shang Han texts. By the seventh or eighth day, the exterior pathogen has resolved, yet chills and fever recur, hence described as "continuing to appear." However, the fever does not persist continuously, hence "intermittent." Inquiry reveals the menses had started but stopped abruptly, indicating residual heat remaining and invading due to deficiency, causing residual blood to congeal, thus resulting in intermittent chills and fever. This is not a transmission from Taiyang (Greater Yang) to Shaoyang (Lesser Yang); rather, the heat generated by congealed blood causes these symptoms, hence resembling malaria. Although the pathogen did not transmit to Shaoyang, Xiao Chai Hu Tang is still used because the Qi of the Blood Chamber is governed by the Liver, and the Liver and Gallbladder are interior-exterior partners. The Gallbladder is affected by the Liver's invasion, manifesting as malaria-like symptoms. Other medications are unsuitable; therefore, the method advocates harmonizing the interior and exterior. When the Qi of the Upper Jiao harmonizes, the suddenly congealed blood will dissipate on its own. Using harsh purgatives, as indicated for Didang Tang (Ephedra and Madder Decoction), would violate the contraindications for Shaoyang disease.
Commentary: The above passage discusses cases where menstruation ends abruptly before completion. Although there is blood congealing, it is not a full excess pattern. Xiao Chai Hu Tang should be modified with Dang Gui (Angelica Sinensis Root), Dan Pi (Moutan Cortex), and Sheng Di Huang (Rehmannia Root) to cool the blood.
