（解毒汤∶黄芩、黄连、黄柏、栀子）
孕妇或感伤寒，或染时令火症，烧热昏昏不退，急用凉药清解，以保其胎，如三黄、解毒、芩、连、羚羊，
惟犀角伤胎之物，不宜用。如不解，至胎损腹中，不得下，孕妇昏愦，斯时极难着手，须验产母之舌。如面赤
舌青，其子已损，急用平胃散加朴硝，服下立出。但死胎不得不下，下之又恐气随下脱，不下又难保产母。倘
面青舌赤，及面舌俱青而口吐白沫者皆两命难存，不可为也。设遇胎下面转赤，尚有一息之存，随即以参
归地救之，间可活十中一二。
热入血分，不用犀角。经曰∶有故无殒，亦无殒也。第不可过剂耳。
平胃散
苍术（二钱） 浓朴（一钱五分） 陈皮（一钱五分） 甘草（八分）
加朴硝（五钱） 煎服。又方∶独用朴硝三四钱，童便一盅和热酒调服，即下。但下后即如产后温补，若
仍作热症医，即错矣。
热病伤胎，下后即用温补，是促其母死耳。（徐评）
凡遇伤寒必保胎，莫与寻常一样猜，最稳只宜香苏饮，分经加味变通来。
香苏饮
香附 紫苏 陈皮 甘草 砂仁
如太阳经加防风，荆芥，秦艽，阳明经加
葛根、知母，少阳经加柴胡、黄芩、人参。
（即是少阳症，邪在半表半里之间）
此症乍寒乍热，过时神清。有一日一发者，有隔日一发者，始则亦宜香苏饮表之。如待寒热分明，始用小
柴胡汤和解之，切勿早用柴胡。若汗多宜加人参，如热盛寒少而有汗，可加石膏、知母以凉散退热，勿致热伤
胎气，早为留意。

[Decoction for Detoxification: composed of Huangqin (Scutellariae Radix), Huanglian (Coptidis Rhizoma), Huangbai (Phellodendri Cortex), and Zhizi (Gardeniae Fructus)]
If a pregnant woman contracts Shanghan (Cold Damage) or is infected with seasonal fire syndromes (warm-heat diseases), presenting with persistent fever and drowsiness, cool-natured herbs must be urgently used to clear heat and resolve the pathogen to protect the fetus. For example, Sanhuang Decoction (Three Yellows Decoction), Jiedu Decoction, Huangqin, Huanglian, and Lingyangjiao (Antelope Horn) may be used. However, Xijiao (Rhinoceros Horn) is a substance that damages the fetus and should not be used. If the condition does not resolve, leading to a dead fetus retained in the uterus unable to be expelled, and the pregnant woman falls into coma, treatment becomes extremely difficult at this stage. One must examine the mother's tongue. If the face is red but the tongue is cyanotic, the fetus has already died; urgently use Pingwei San (Regulate the Stomach Powder) added with Poxiao (Mirabilite). After ingestion, the dead fetus will be expelled immediately. However, the dead fetus must be expelled; yet, after expulsion, there is fear of Qi collapsing with the expulsion, while failing to expel it makes it difficult to save the mother. If the face is cyanotic and the tongue is red, or if both face and tongue are cyanotic accompanied by foaming at the mouth, both lives are difficult to save, and no cure is possible. If, upon expulsion of the fetus, the discharge turns red, indicating a remaining breath of life, one should immediately administer Shengmai San-like rescue with Renshen (Ginseng), Danggui (Angelicae Sinensis Radix), and Dihuang (Rehmanniae Radix); occasionally, one or two out of ten may survive.
When Heat enters the Blood level, Xijiao (Rhinoceros Horn) is not used. The classic states: "Where there is pathology, there is no injury [to the healthy body], nor injury to the fetus." It is merely necessary not to overdose.
[Pingwei San]
Cangzhu (Atractylodis Rhizoma) (2 qian) Nongpo (Magnoliae Officinalis Cortex) (1.5 qian) Chenpi (Citri Reticulatae Pericarpium) (1.5 qian) Gancao (Glycyrrhizae Radix et Rhizoma) (0.8 qian)
Add Poxiao (Mirabilite) (5 qian), decoct and take. Another prescription: Use only Poxiao (Mirabilite) 3-4 qian, mixed with one cup of Tongbian (Child's Urine) and warm wine, taken orally; the dead fetus will be expelled immediately. However, after expulsion, treatment should follow postpartum warming and tonifying protocols. If treated as a Heat syndrome again, it would be an error.
Treating fetal damage from Heat disease by using warming and tonifying methods immediately after expulsion of the dead fetus accelerates the mother's death. (Comment by Xu)
Whenever Shanghan (Cold Damage) is encountered, the fetus must be protected; do not guess casually as with ordinary cases. The most stable approach is to use Xiangsu Yin (Fragrant Perilla Infusion), varying it according to channel differentiation.

Xiangfu (Cyperi Rhizoma) Zisu (Perillae Folium) Chenpi (Citri Reticulatae Pericarpium) Gancao (Glycyrrhizae Radix et Rhizoma) Sharen (Amomi Fructus Rotundus)
For Taiyang Channel (Taiyang Meridian) involvement, add Fangfeng (Saposhnikoviae Radix), Jingjie (Schizonepetae Herba), and Qinjiao (Gentianae Macrophyllae Radix). For Yangming Channel (Yangming Meridian) involvement, add Gegen (Puerariae Lobatae Radix) and Zhimu (Anemarrhenae Rhizoma). For Shaoyang Channel (Shaoyang Meridian) involvement, add Chaihu (Bupleuri Radix), Huangqin (Scutellariae Radix), and Renshen (Ginseng).
(This is a Shaoyang Syndrome, where the pathogen is between the exterior and interior.)
This syndrome presents with alternating chills and fever, with clarity of spirit returning after intervals. It may occur once daily or every other day. Initially, Xiangsu Yin (Fragrant Perilla Infusion) should be used to release the exterior. Wait until the chills and fever are distinct before using Xiaochaihu Tang (Minor Bupleurum Decoction) to harmonize. Do not use Chaihu (Bupleuri Radix) too early. If sweating is profuse, add Renshen (Ginseng). If Heat is severe with mild chills and sweating, add Shigao (Gypsum Fibrosum) and Zhimu (Anemarrhenae Rhizoma) to cool and dissipate Heat, preventing Heat from damaging the fetal Qi; attention must be paid early.
