孕妇麻症若相当。潮热蒸蒸胎易伤。子去母应无害事。症轻子母两无殃。
大热蒸蒸血海干。毒火内攻胎不安。急宜清热养营血。治不根据法生祸端。
古云。胎遇热则坠。麻为火候。内必有热。最易坠胎。孕妇出麻。此症极险。当于初热未出之
时。须察其热之轻重。正出之际。须验其麻色之红淡。法宜疏解。佐以清凉滋血安胎之药。不可
犯动胎气。初热时。宜用参苏饮去人参、半夏、木香、陈皮。加条实子芩、大腹皮以发之。或以四
物汤（见二十五条）加子芩、荆芥、苏叶、蕲艾主之。或以四物汤（见二十五条）加白术钱半、子芩、
蕲艾、枳壳、砂仁各二钱主之。或以安胎散、罩胎散主之。始终以安胎清热为主。则胎不动而麻易
出。此理诚当。愚按、孕妇出麻初热之时。而用四物汤加白术、艾叶、砂仁。与夫安胎散、罩胎散、
方中之人参、白术、川芎、砂仁、香附、白芍等味。恐燥悍之药。触动毒火。而热转甚。酸收之味。敛
固毒火。毒只内攻。麻难得出。症必增危。非但坠胎。且难保妊妇无虞。即如参苏饮。虽曰除去人
参、半夏、木香、陈皮。而要知桔梗、甘草亦不宜遽用。莫若以宣毒发表汤（见第五条）去升麻、桔
梗、甘草、枳壳、木通。加当归、条实子芩、生地黄、元参、酒炒黄连主之。使麻毒透出。内热自退。
而胎自安矣。麻出之后。则宜以四物汤（见二十五条）加条子芩、黄连、牛蒡子之类主之。至于麻
收之后。亦宜以四物（见二十五条）为主。如安胎散、罩胎散、四物加白术、砂仁、蕲艾、及安胎饮
等方。俱可加减选用。倘无溏泻。而大便闭涩结滞者。则人参、白术。又当慎用。大抵凡一切实脾
行气温燥之药。既碍麻症。复伤子气。咸宜禁用为是。
朱曰 妊娠出麻。在不知者必诧为希奇。其实男子在三十以内。亦间出麻。盖麻为先天
遗毒。于本人气血。原相融洽。故能留藏许久。而始发出。所云燥悍之药。触动
毒火。酸敛之味。敛固毒火。真是至理名言。当奉为金科玉律。

If the measles in a pregnant woman are moderate in severity, although tidal fever and steaming heat may occur causing potential harm to the fetus; if the mother's righteous qi remains sufficient, there will be no major issue even if the fetus is lost; if the symptoms are mild, both mother and child will remain unharmed.
If high fever and steaming heat deplete the Blood Sea (Chong Mai, which stores blood), and toxic fire attacks internally causing fetal instability, it is urgent to clear heat and nourish Ying-Blood. If treatment does not follow correct principles, disaster will ensue.
Ancient texts state: "The fetus falls when exposed to heat." Measles belong to the category of dry and hot pathogenic factors, inevitably generating internal heat, which most easily leads to abortion. Measles during pregnancy is an extremely critical condition. During the initial fever stage before the rash appears, one must carefully observe the severity of the fever; during the eruption phase, one must examine whether the color of the measles is bright red or pale. The treatment method should involve dispersing and resolving the exterior, assisted by cooling, blood-nourishing, and fetal-anchoring herbs. One must avoid using herbs that disturb the fetal qi.
During the initial fever stage, Shen Su Yin (Ginseng and Perilla Decoction) should be used, removing Ren Shen (Ginseng), Ban Xia (Pinellia Rhizome), Mu Xiang (Aucklandiae Radix), and Chen Pi (Citrus Peel), and adding Tiao Shi Zi Qin (Scutellariae Radix) and Da Fu Pi (Arecae Pericarpium) to promote eruption. Alternatively, Si Wu Tang (Four Substances Decoction) (see Article 25) can be used with added Zi Qin (Scutellariae Radix), Jing Jie (Schizonepetae Herba), Su Ye (Perillae Folium), and Qi Ai (Artemisiae Argyi Folium). Or, Si Wu Tang (see Article 25) can be used with added Bai Zhu (Atractylodis Macrocephalae Rhizoma, 1.5 qian), Zi Qin, Qi Ai, Zhi Qiao (Aurantii Fructus), and Sha Ren (Amomi Fructus, each 2 qian). Or, An Tai San (Fetal-Anchling Powder) or Zhao Tai San (Fetal-Covering Powder) can be used as the main formula. The principle should always be anchoring the fetus and clearing heat, so that the fetal qi remains stable and the measles erupt easily. This theory is indeed sound.
However, I opine that during the initial fever stage of measles in pregnancy, using Si Wu Tang with Bai Zhu, Ai Ye (Artemisiae Argyi Folium), and Sha Ren, as well as formulas like An Tai San and Zhao Tai San containing herbs such as Ren Shen, Bai Zhu, Chuan Xiong (Ligustici Chuanxiong Rhizoma), Sha Ren, Xiang Fu (Cyperi Rhizoma), and Bai Shao (Paeoniae Radix Alba), these dry and aggressive herbs might stir up toxic fire, exacerbating the heat. Sour and astringent flavors might consolidate the toxic fire internally, preventing it from venting outward, making it difficult for the measles to erupt, thereby worsening the condition dangerously. This could lead not only to abortion but also endanger the pregnant woman's life.
Take Shen Su Yin, for example. Although Ren Shen, Ban Xia, Mu Xiang, and Chen Pi are removed, one must realize that Jie Geng (Platycodonis Radix) and Gan Cao (Glycyrrhizae Radix et Rhizoma) should also not be used hastily. It is better to use Xuan Du Fa Biao Tang (Toxin-Releasing Exterior-Dispersing Decoction) (see Article 5), removing Sheng Ma (Ephedrae Herba - *Note: Text says Shengma but usually refers to Cimicifugae Rhizoma in this context, however literal translation of character is Ephedra, but standard TCM Sheng Ma is Cimicifuga. Given context of measles eruption, likely Cimicifuga, but sticking to text literalism or standard term? Standard term for 升麻 is Cimicifugae Rhizoma. I will use Cimicifugae Rhizoma*), Jie Geng, Gan Cao, Zhi Qiao, and Mu Tong (Akebiae Caulis), and adding Dang Gui (Angelicae Sinensis Radix), Tiao Shi Zi Qin, Sheng Di Huang (Rehmanniae Radix), Yuan Shen (Scrophulariae Radix), and Jiu Chao Huang Lian (Coptidis Rhizoma fried with wine). This allows the measles toxin to vent outward, internal heat will naturally recede, and the fetus will stabilize.
After the measles have erupted, Si Wu Tang (see Article 25) with added Zi Qin, Huang Lian (Coptidis Rhizoma), and Niu Bang Zi (Arctii Fructus) should be used as the main formula. After the measles have resolved, Si Wu Tang (see Article 25) should still be the basis. Formulas such as An Tai San, Zhao Tai San, Si Wu Tang with Bai Zhu, Sha Ren, Qi Ai, and An Tai Yin (Fetal-Anchoring Decoction) can all be selected and modified as needed. If there is no loose stool, but constipation and stagnation, then Ren Shen and Bai Zhu should be used with caution. Generally, all herbs that strengthen the spleen, move qi, and are warm and dry should be strictly prohibited, as they hinder the measles pathology and damage the fetal qi.
Zhu stated: Measles during pregnancy seem rare to those unfamiliar with them. In fact, men under thirty also occasionally contract measles. Measles are considered congenital latent toxins that originally harmonize with the individual's qi and blood, allowing them to remain dormant for a long time before erupting. The statement that "dry and aggressive herbs stir up toxic fire, while sour and astringent flavors consolidate toxic fire" is truly profound wisdom and should be regarded as an inviolable rule.
