且夫天地阴阳，各有分位，伤寒杂病，岂无各科，男妇何可同治也。男子调气为主，女子养血
为先。女子血蓄，则血室不蓄，二气和平。一有凝结，水火相刑。凡气口紧盛者，即宜下。人迎紧
盛者，即宜汗。但妇人左关浮紧者，不可下，当发汗，以救血室。荣卫得和，津液得行，浃然汗出
而解。凡妇人经水适断，昼则明了，暮则谵语，如见鬼状，此为热入血室。无犯胃气及上中二焦，
言无犯胃气者，谓不可下也，以小柴胡汤主之。若行阳迟则热入胃，令津液燥，中焦、上焦不荣，成
血
结胸，须针期门可也。但妇人伤寒，发热恶寒，四肢拘急，口燥舌干，经脉凝滞不得往来，以桂枝
红花汤。
若伤寒，口燥咽干，不思饮食，以黄芩芍药汤。
若伤寒，喘急烦躁，战而作寒，阴阳俱虚，不可下也，以小柴胡汤。
若伤寒，经水适来，邪乘虚而入，昼则明了，暮则谵语，如见鬼状，此为热入血室，无犯上中
二焦胃气者，宜小柴胡汤。
若伤寒，瘥后犹有余热不去，谓之遗热，宜地黄汤主之。
《黄帝内经》曰∶有故无殒也。大积大聚，其可犯也。损其大半而止，过则杀也。且妊妇伤寒，
保胎宜阿胶散。大抵妊妇伤寒，仲景无治法，最宜避忌，诸药不可以寻常例视之。凡妊妇用安胎饮，
散寒邪以白术汤。
妊妇憎寒壮热，宜发其汗，以芍药汤。妊妇或中时行，洒淅寒热，作寒振栗而
悸，如哕者，宜苏木汤。妊妇伤热，默默欲眠，不欲食，胁下痛，呕逆痰气，及产后病伤风，热入
胞宫，寒热如疟，并经水适来适断，病后劳复，饮热不解，以黄龙汤。妊妇头目眩疼，壮热心躁，
以旋覆花汤。妊妇发斑，以栀子大青汤。
Furthermore, Yin and Yang in heaven and earth each have their specific positions and attributes. Are there not different specialties for Shanghan (Cold Damage) diseases and miscellaneous diseases? How can men and women be treated in the same manner? The treatment for men primarily focuses on regulating Qi (vital energy), while for women, nourishing Blood takes precedence. If a woman's Blood is stored and flows smoothly, the Blood Chamber (uterus and related blood vessels) will not stagnate, and the two Qi (Yin and Yang) will remain in harmony. Once condensation occurs, Water and Fire will punish each other (indicating disharmony between Yin and Yang, or cold-heat complex). Wherever the Qi Kou pulse (right radial artery, reflecting Lung and Qi status) is tight and vigorous, purgation should be employed. Wherever the Ying Ren pulse (left radial artery or neck artery, here referring to exterior syndrome or Yang meridian pathology) is tight and vigorous, diaphoresis should be employed. However, if a woman's left Guan pulse (reflecting Liver status) is floating and tight, purgation must not be used; instead, diaphoresis should be applied to rescue the Blood Chamber. When Ying and Wei (Nutritive and Defensive Qi) are harmonized and body fluids circulate freely, the patient will recover through mild sweating.
Whenever a woman’s menstruation has just ceased, she is clear-minded during the day but delirious at dusk, seeing things as if ghosts were present, this is Heat entering the Blood Chamber. One must not harm Stomach Qi or the Qi of the Upper and Middle Jiao (Upper and Middle Burners). "Not harming Stomach Qi" means one must not use purgation; instead, Xiao Chai Hu Tang (Minor Bupleurum Decoction) should be administered. If Yang movement is sluggish causing Heat to enter the Stomach, drying up body fluids, and failing to nourish the Middle and Upper Jiao, it results in Blood-Jie Xiong (Blood Bind-Chest, a condition where blood stasis and heat bind in the chest/diaphragm); in such cases, needling the Qimen (LR14) acupoint is required.
If a woman suffers from Shanghan with fever and aversion to cold, spasm and stiffness of the four limbs, dry mouth and tongue, and stagnant meridians preventing smooth flow, Gui Zhi Hong Hua Tang (Cinnamon Twig and Safflower Decoction) should be used.
If Shanghan presents with dry mouth and throat, and loss of appetite, Huang Qin Shao Yao Tang (Scutellaria and Peony Decoction) should be used.
If Shanghan presents with panting, urgency, irritability, shivering followed by coldness, and deficiency of both Yin and Yang, purgation is contraindicated; Xiao Chai Hu Tang (Minor Bupleurum Decoction) should be used.
If Shanghan occurs while menstruation is currently flowing, pathogenic factors enter due to deficiency. The patient is clear-minded during the day but delirious at dusk, seeing things as if ghosts were present. This is also Heat entering the Blood Chamber. One must not harm the Qi of the Upper and Middle Jiao and Stomach Qi; Xiao Chai Hu Tang (Minor Bupleurum Decoction) is appropriate.
If after recovery from Shanghan, residual heat remains unexpelled, this is called residual heat (Yi Re); Di Huang Tang (Rehmannia Decoction) should be administered.
The Huang Di Nei Jing (Yellow Emperor’s Inner Canon) states: "When there is an existing disease, the medicine attacks the disease without injuring the healthy Qi." For large accumulations and聚 (masses), attack is permissible. However, stop when half or more of the pathogen is eliminated; exceeding this limit will kill the patient.
Regarding pregnant women suffering from Shanghan, Bao Tai San (Fetus-Safeguarding Powder) is suitable for protecting the fetus. Generally speaking, Zhang Zhongjing did not provide specific treatment methods for Shanghan in pregnancy; extreme caution is advised, and ordinary medications cannot be viewed through standard rules. Whenever An Tai Yin (Fetus-Anchoring Infusion) is used for pregnant women, Bai Zhu Tang (Atractylodes Macrocephala Decoction) is used to disperse cold pathogens.
For pregnant women experiencing aversion to cold and high fever, diaphoresis is indicated using Shao Yao Tang (Peony Decoction). If a pregnant woman contracts seasonal epidemic pathogens, presenting with alternating chills and fever, trembling chills accompanied palpitations, or hiccups, Su Mu Tang (Sappan Wood Decoction) is appropriate. For pregnant women injured by heat, presenting with silent desire to sleep, anorexia, hypochondriac pain, vomiting with rebellious Qi and phlegm, as well as postpartum wind injury, Heat entering the Bao Gong (Uterine Palace), alternating chills and fever resembling malaria, menstruation just starting or stopping, relapse after illness due to overexertion, and inability to resolve symptoms by drinking hot water, Huang Long Tang (Yellow Dragon Decoction) should be used. For pregnant women with dizziness and headache of the head and eyes, high fever, and mental restlessness, Xuan Fu Hua Tang (Inula Flower Decoction) is indicated. For pregnant women developing macules/rashes, Zhi Zi Da Qing Tang (Gardenia and Isatis Root Decoction) should be used.
