春温妇女往来寒热，经水适来，病发适断，昼
明夜昏，此热入血室。宜用小柴胡汤去半夏，加归
尾、桃仁·山楂、丹皮、赤芍、广郁金、鲜菖蒲等
味，破瘀透邪也。
仲景云：妇女伤寒，经水适来，热则适断，寒热往来，
昼则明了，夜则谵语，此热入血室，当刺期门穴。此穴在胁
下，肝之络也。血室者，血海也。考<内经>，冲脉为血
海。又心主血，脾统血，肝藏血。凡妇女经水贮于冲脉，必
由肝牌心三脏之续扰而能蓄泄有常。今热由少阳传入血海，
则瘀滞不行。血厉阴，夜亦属阴。凡人卫气，昼则行阳，夜
(1)犀角地黄汤：《伤寒论》无此方·乃后世注家之意
则行阴，故入血之邪，至夜则剧。陶氏仿小柴胡汤升泄少
阳，加归尾，桃仁、赤芍、丹皮、山楂凉血祛瘀，兼郁金、
菖蒲宣窍透邪，甚者加大黄、鳖虫逐之。总之，临症之识，
不外气血营卫，阴阳表里，用药之要，得中寒热温凉汗吐下
和而已也。
春温表证未解，大便忽泻，胸腕痞满，按之不
痛，舌黄脉滑，此邪陷成痞。宜用泻心汤，苦降辛通
也。
仲景论痞，都因误下邪陷而成。今表症未解，而忽加泄
泻，与误下之意相同。以致表邪乘虚陷入，势欲下泄。奈其
人胃气尚强，与热相抗，而邪难直泄。因而阻遏心下，蕴结
不散，遂致有形，按之不痛。斯时表之则邪难外越，攻之则
邪不下走。故仲景用泻心汤，得芩、连之苦寒泄热，半夏之
辛温通阳，积实(1)之苦燥破结，虚者合人参之甘温扶正，名
为泻心，非泻心也，乃泻心下之痞满耳。
春温病中，妇女出现寒热往来（忽冷忽热），月经恰好来潮，或发病时月经刚断，白天神志清醒，夜晚昏沉谵语，这是热邪陷入血室（子宫及冲脉等与月经相关的血分领域）的表现。适宜使用小柴胡汤（和解少阳的代表方剂）去掉半夏，加入当归尾、桃仁、山楂、牡丹皮、赤芍、广郁金、鲜石菖蒲等药物，以破除瘀血、透达邪气。
张仲景说：妇女患伤寒，月经恰好来潮，若遇热邪则经水突然中断，出现寒热往来，白天神志清楚，夜晚说胡话，这是热入血室，应当针刺期门穴。此穴位于胁下，是肝脏的络脉所在。所谓血室，就是血海。考证《黄帝内经》，冲脉被称为血海。另外，心主司血液，脾统摄血液，肝贮藏血液。凡是妇女的经血贮存在冲脉中，必须依赖肝、脾、心三脏的协调运作，才能蓄积和排泄有常度。如今热邪由少阳传入血海，导致瘀滞不通。血属于阴，夜晚也属阴。人体的卫气，白天运行于阳分，夜晚运行于阴分，所以侵入血分的邪气，到了夜晚就会加剧。陶氏（指清代医家陶华或后世仿效者）模仿小柴胡汤升散宣泄少阳之邪，加入当归尾、桃仁、赤芍、牡丹皮、山楂以凉血祛瘀，兼用郁金、石菖蒲宣通心窍、透达邪气，病情严重的加大黄、䗪虫（土鳖虫）以驱逐瘀血。总之，临证辨别的识见，不外乎气血营卫、阴阳表里；用药的要旨，不过是掌握寒热温凉以及汗、吐、下、和等治法罢了。
春温病表证尚未解除，大便忽然腹泻，胸脘部痞塞胀满，按压时不疼痛，舌苔黄，脉滑，这是邪气内陷形成痞证（气机阻滞而成的痞块）。适宜使用泻心汤，采用苦味降泄、辛味通散的治法。
张仲景论述痞证，多因误用攻下法导致邪气内陷而成。如今表证未解，却忽然出现泄泻，这与误用攻下法的机理相同。致使表邪乘虚内陷，势欲向下排泄。无奈患者胃气尚强，与热邪相抗，导致邪气难以直接排出。因而阻遏在心下（胃脘部），蕴结不散，遂形成有形之感，但按压时不痛。此时若发汗解表，则邪气难以向外透越；若攻下逐邪，则邪气又不向下走泄。因此张仲景使用泻心汤，利用黄芩、黄连的苦寒性质泄热，半夏的辛温性质通阳，枳实的苦燥性质破结消痞，体质虚弱者合用人参的甘温性质扶助正气。名为“泻心”，并非真的泻心脏，而是治疗心下部位的痞满症状。
In the context of Spring-Warmth disease, if a woman experiences alternating chills and fever (alternating cold and heat), her menses happen to commence, or the illness occurs just as menstruation ceases, with clear consciousness during the day but confusion or delirium at night, this indicates Heat entering the Blood Chamber (the uterus and related blood vessels such as the Chong Mai). The appropriate treatment is Xiaochaihu Tang (Minor Bupleurum Decoction), removing Banxia (Pinelliae Rhizoma), and adding Dangguiwei (Angelicae Sinensis Radix caudex), Taoren (Persicae Semen), Shanzha (Crataegi Fructus), Danpi (Moutan Cortex), Chishao (Paeoniae Radix Rubra), Guang Yujin (Curcumae Longae Radix), and Xian Changpu (Acori Tatarinowii Rhizoma) to break up stasis and expel pathogens.
Zhang Zhongjing stated: When a woman contracts Cold Damage (Shanghan) and her menses happen to arrive, if Heat causes the flow to stop abruptly, resulting in alternating chills and fever, clear mind by day, and delirium by night, this is Heat entering the Blood Chamber. One should puncture the Qimen acupoint. This point is located under the hypochondrium and is the collateral connection of the Liver. The Blood Chamber refers to the Sea of Blood. According to the *Neijing* (Inner Canon), the Chong Mai (Penetrating Vessel) is the Sea of Blood. Furthermore, the Heart governs Blood, the Spleen controls Blood, and the Liver stores Blood. In women, menstrual blood is stored in the Chong Mai, and its proper accumulation and discharge depend on the coordinated function of the Liver, Spleen, and Heart. Now, if Heat transmits from the Shaoyang (Lesser Yang) into the Sea of Blood, it causes stasis and obstruction. Blood belongs to Yin, and night also belongs to Yin. The body's Wei Qi (Defensive Qi) travels through the Yang aspects during the day and the Yin aspects at night; therefore, pathogens that have entered the Blood manifest more severely at night. Tao氏 imitated Xiaochaihu Tang to ascend and vent Shaoyang pathogens, adding Dangguiwei, Taoren, Chishao, Danpi, and Shanzha to cool the blood and dispel stasis, while using Yujin and Changpu to open the orifices and vent pathogens. In severe cases, Dahuang (Rhei Radix et Rhizoma) and Ezhong (Eupolyphaga seu Steleophaga) are added to drive out the stasis. In summary, clinical discernment revolves around Qi, Blood, Ying (Nutritive) Qi, Wei Qi, Yin-Yang, and Exterior-Interior. The essence of medication lies in balancing Cold-Hot-Warm-Cool and employing Sweating, Vomiting, Purging, and Harmonizing methods appropriately.
If the Exterior syndrome of Spring-Warmth has not yet resolved, but sudden diarrhea occurs, accompanied by fullness and stagnation in the chest and epigastrium, which is painless upon pressure, with a yellow tongue coating and slippery pulse, this indicates pathogens sinking inward to form Pi Syndrome (obstructive fullness). The appropriate treatment is Xiexin Tang (Drain the Epigastrium Decoction), utilizing bitter descending and pungent unblocking methods.
Zhang Zhongjing discusses Pi Syndrome, attributing it mostly to pathogens sinking inward due to erroneous purgative therapy. Here, the Exterior syndrome remains unresolved, yet sudden diarrhea appears, similar in mechanism to erroneous purgation. Consequently, Exterior pathogens sink inward exploiting the deficiency, intending to exit downward. However, the patient's Stomach Qi remains strong, resisting the Heat, making direct expulsion difficult. Thus, the pathogen obstructs the area below the heart (epigastrium), accumulates without dispersing, forming a sensation of fullness, though painless on palpation. At this stage, sweating would fail to release the pathogen externally, while purging would fail to guide it downward. Therefore, Zhang Zhongjing employs Xiexin Tang: Huangqin (Scutellariae Radix) and Huanglian (Coptidis Rhizoma) use their bitter-cold nature to drain Heat; Banxia (Pinelliae Rhizoma) uses its pungent-warm nature to unblock Yang; Zhishi (Aurantii Fructus Immaturus) uses its bitter-dry nature to break up knots. For deficient patients, Renshen (Ginseng Radix) is added for its sweet-warm nature to support Zheng Qi (Upright Qi). It is named "Draining the Heart," but it does not actually drain the Heart organ; rather, it treats the fullness and stagnation in the epigastric region.
