妊妇有畏寒腹疼，因而堕胎者，人只知下部太寒也，谁知是气虚不能摄胎乎！夫人生于火，亦养于火，非气不
充，气旺则火旺，气衰则火衰。人之所以坐胎者，受父母先天之真火也。先天之真火，即先天之真气以成之。故胎
成于气，亦摄于气，气旺则胎牢，气衰则胎堕，胎日加长，而气日加衰，安得不堕哉！况又遇寒气外侵，则内之
火气更微，火气微则长养无资；此胎之不能不堕也。使当其腹疼之时，即用人参、干姜之类，补气祛寒，则可以疼
止而胎安。无如人拘于妊娠之药禁而不敢用，因致堕胎，而仅存几微之气，不急救气，尚有何法。
方用黄 补气汤。
黄 （二两，生用） 肉桂（五分，去粗皮，研） 当归（一两，酒洗）
水煎服。五剂愈矣。倘认定是寒，大用辛热，全不补气与血，恐过于燥热，反致亡阳而变危矣。
眉批∶肉桂须用好的，如无佳者，用炮姜代之，或一钱、二钱皆可，不可只用五分。
歌括∶妊妇腹痛畏寒凉，小产原因气虚张。
气旺胎牢气衰堕，此理精微细思量。
黄 补气生用良，二两黄 一两当。
肉桂五分同煎服，五剂全愈效非常。
妊妇有大怒之后，忽然腹疼吐血，因而堕胎；及堕胎之后，腹疼仍未止者，人以为肝之怒火未退也，谁知是血
不归经而然乎！夫肝所以藏血者也。大怒则血不能藏，宜失血而不当堕胎，何为失血而胎亦随堕乎？不知肝性最
急，血门不闭，其血直捣于胞胎，胞胎之系，通于心肾之间，肝血来冲，必断绝心肾之路；胎因心肾之路断，胞胎
失水火之养，所以堕也。胎既堕矣，而腹疼如故者，盖因心肾未接，欲续无计，彼此痛伤肝气，欲归于心而心不
受，欲归于肾而肾不纳，故血犹未静而疼无已也。治法宜引肝之血，仍入于肝，而腹疼自已矣。然徒引肝之血而不
平肝之气，则气逆而不易转，即血逆而不易归也。
方用引气归血汤。
白芍（五钱，酒炒） 当归（五钱，酒洗） 白术（三钱，土炒） 甘草（一钱） 黑芥穗（三钱） 丹皮（三
钱） 姜炭（五分） 香附（五分，酒炒） 麦冬（三钱，去心） 郁金（一钱，醋炒）
水煎服。此方名为引气，其实仍是引血也，引血亦所以引气，气归于肝之中，血亦归于肝之内，气血两归，而腹疼
自止矣。
眉批∶产后忌用白芍，因其酸寒也。胎堕后用白芍五钱，惟上元生人可用，若下元生人万不可用。必不得已
而用之，将白芍炒炭，用三钱也可。余药如法制。
歌括∶妊妇大怒血门开，其血直捣入胞胎。
胞胎之系通心肾，心肾路塞胎堕哉。
引气归血芍当归，术麦丹皮荆芥穗。
姜炭郁金香附草，煎服气归血亦回。
孕妇如果有畏寒、腹痛，从而导致流产的，人们只知道是下焦太寒了，哪里知道这是气虚不能固摄胎儿呢！人生于火，也靠火来滋养，如果没有充足的气，气旺盛则火旺盛，气衰弱则火衰弱。人之所以能安胎，是因为接受了父母先天的真火。先天的真火，就是由先天的真气形成的。所以胎儿形成于气，也依靠气来固摄，气旺盛则胎儿牢固，气衰弱则胎儿坠落，随着胎儿一天天长大，母体的气却一天天衰弱，怎么能不流产呢！况且又遇到寒气从外部侵袭，那么体内的火气就更加微弱，火气微弱则缺乏滋养胎儿的资源；这就是胎儿不得不流产的原因。如果在腹痛的时候，立即使用人参、干姜之类的药物，补气祛寒，就可以使疼痛停止而胎儿安稳。无奈人们拘泥于妊娠期间的用药禁忌而不敢使用，因此导致流产，只剩下微弱的元气，如果不紧急救治元气，还有什么办法呢？
方用黄芪补气汤。
黄芪（二两，生用） 肉桂（五分，去粗皮，研碎） 当归（一两，酒洗）
水煎服。五剂即可痊愈。如果认定是寒证，大量使用辛热药物，完全不补气和血，恐怕过于燥热，反而会导致亡阳而出现危重情况。
眉批：肉桂必须用好货，如果没有好的，可以用炮姜代替，用量一钱或二钱都可以，不可只用五分。
歌括：孕妇腹痛畏寒凉，小产原因是因为气虚张扬。
气旺胎儿牢固气衰胎儿坠落，这个道理精微需要仔细思量。
黄芪补气宜生用，二两黄芪一两当归。
肉桂五分同煎服，五剂全愈效果非常。
孕妇在大怒之后，突然腹痛吐血，从而导致流产；以及流产之后，腹痛仍然没有停止的，人们认为是肝中的怒火没有消退，哪里知道这是血液不能回归经脉所致呢！肝是用来藏血的器官。大怒则血液不能藏纳，应该出现失血而不应当流产，为什么失血的同时胎儿也随之流产呢？不知道肝的性质最急躁，血门不关闭，血液直接冲击胞胎，胞胎的系带，连通在心肾之间，肝血冲来，必然切断心肾之间的通路；胎儿因为心肾通路中断，胞胎失去了水火之气的滋养，所以流产。胎儿既然已经流产，而腹痛依旧，这是因为心肾尚未接通，想要接续却没有办法，彼此痛伤肝气，想要归于心但心不接受，想要归于肾但肾不收纳，所以血液仍然不稳定而疼痛不止。治疗方法应当引导肝脏的血液，重新进入肝脏，那么腹痛自然就会停止。然而仅仅引导肝脏的血液而不平抑肝的气机，那么气逆乱就不容易回转，即血液逆乱也不容易回归。
方用引气归血汤。
白芍（五钱，酒炒） 当归（五钱，酒洗） 白术（三钱，土炒） 甘草（一钱） 黑芥穗（三钱） 丹皮（三钱） 姜炭（五分） 香附（五分，酒炒） 麦冬（三钱，去心） 郁金（一钱，醋炒）
水煎服。这个方子名字叫引气，其实仍然是引血，引血也就是为了引气，气归于肝中，血也归于肝内，气血两归，腹痛自然停止。
眉批：产后忌用白芍，因为它是酸寒性质的。胎儿流产后使用白芍五钱，只有上元生人可以使用，如果是下元生人万万不可使用。如果不得已而使用，将白芍炒成炭，用三钱也可以。其余药物按照此法制备。
歌括：孕妇大怒血门开，其血直接冲击进入胞胎。
胞胎的系带连通心肾，心肾通路堵塞胎儿流产啊。
引气归血用白芍和当归，白术麦冬丹皮荆芥穗。
姜炭郁金香附草，煎服气归血亦回。
If a pregnant woman experiences aversion to cold and abdominal pain, leading to miscarriage, people only know that the lower jiao (Lower Burner) is too cold, but who knows that this is due to Qi deficiency failing to secure the fetus! Human life originates from Fire and is also nourished by Fire. Without sufficient Qi, when Qi is vigorous, Fire is vigorous; when Qi declines, Fire declines. The reason one can maintain pregnancy is receiving the True Fire of the parents' congenital essence. This congenital True Fire is formed by the congenital True Qi. Therefore, the fetus is formed by Qi and secured by Qi; when Qi is vigorous, the fetus is firm; when Qi declines, the fetus falls. As the fetus grows day by day, the mother's Qi declines day by day, how could it not miscarry! Moreover, if external Cold pathogen invades, the internal Fire Qi becomes even more微弱 (weak); with weak Fire Qi, there is insufficient resource for nourishment and growth; this is why the fetus inevitably miscarries. If at the time of abdominal pain, one immediately uses herbs like Ren Shen (Ginseng Root) and Gan Jiang (Dried Ginger) to tonify Qi and dispel Cold, the pain would stop and the fetus would be safe. Unfortunately, people are constrained by pregnancy medication taboos and dare not use them, resulting in miscarriage, leaving only a trace of Qi remaining. If Qi is not urgently rescued, what other method is there?
Prescription: Huang Qi Bu Qi Tang (Astragalus Qi-Tonifying Decoction).
Huang Qi (Astragali Radix, 2 liang, raw), Rou Gui (Cinnamomi Cortex, 5 fen, bark removed, powdered), Dang Gui (Angelicae Sinensis Radix, 1 liang, wine-washed).
Decoct in water and take orally. Five doses will cure it. If one assumes it is merely Cold and heavily uses acrid-hot herbs without tonifying Qi and Blood, fearing excessive dryness-heat might lead to Yang collapse and critical danger.
Commentary: Rou Gui must be high quality. If none is available, Pao Jiang (Charred Ginger Rhizome) can be substituted, using 1 qian or 2 qian; do not use only 5 fen.
Song Verse: Pregnant women with abdominal pain and aversion to cold, miscarriage is caused by Qi deficiency being prominent.
When Qi is vigorous, the fetus is firm; when Qi declines, the fetus falls; this principle is subtle and requires careful contemplation.
Huang Qi tonifies Qi and should be used raw; two liang of Huang Qi and one liang of Dang Gui.
Rou Gui 5 fen decocted together; five doses bring complete recovery with extraordinary effect.
After a pregnant woman suffers great anger, sudden abdominal pain and hemoptysis occur, leading to miscarriage; and after miscarriage, the abdominal pain does not cease. People assume it is because the Liver Fire has not subsided, but who knows that this is due to Blood failing to return to its vessels! The Liver stores Blood. Great anger causes Blood to fail to be stored, leading to hemorrhage, but why does miscarriage accompany hemorrhage? One does not realize that the nature of the Liver is most urgent/irritable. When the "blood gate" does not close, Blood rushes directly into the Bao Tuo (uterus/fetal sac). The ligament of the Bao Tuo connects between the Heart and Kidney. The rushing Liver Blood must sever the pathway between the Heart and Kidney; because this pathway is severed, the Bao Tuo loses the nourishment of Water and Fire, hence the miscarriage. Since the fetus has miscarried but abdominal pain remains, it is because the Heart and Kidney have not reconnected, and there is no way to restore the connection. They mutually injure the Liver Qi; attempting to return to the Heart but the Heart does not accept it, attempting to return to the Kidney but the Kidney does not receive it. Thus, Blood remains unsettled and pain continues unceasingly. The treatment method should guide the Liver's Blood back into the Liver, and abdominal pain will naturally stop. However, merely guiding Liver Blood without soothing Liver Qi means Qi rebellion will not easily reverse, and thus Blood rebellion will not easily return.
Prescription: Yin Qi Gui Xue Tang (Qi-Guiding-to-Blood Decoction).
Bai Shao (Paeoniae Radix Alba, 5 qian, wine-fried), Dang Gui (Angelicae Sinensis Radix, 5 qian, wine-washed), Bai Zhu (Atractylodis Macrocephalae Rhizoma, 3 qian, earth-fried), Gan Cao (Glycyrrhizae Radix et Rhizoma, 1 qian), Hei Jie Sui (Schizonepetae Spica, charred, 3 qian), Dan Pi (Moutan Cortex, 3 qian), Jiang Tan (Zingiberis Rhizoma Carbonisatum, 5 fen), Xiang Fu (Cyperi Rhizoma, 5 fen, wine-fried), Mai Dong (Ophiopogonis Radix, 3 qian, heart removed), Yu Jin (Curcumae Radix, 1 qian, vinegar-fried).
Decoct in water and take orally. This prescription is named "Guiding Qi," but essentially it guides Blood; guiding Blood is also guiding Qi. When Qi returns to the interior of the Liver, Blood also returns to the interior of the Liver; with both Qi and Blood returning, abdominal pain stops naturally.
Commentary: Bai Shao is contraindicated postpartum due to its sour-cold nature. Using 5 qian of Bai Shao after miscarriage is only suitable for those born in the "Upper Yuan" period; for those born in the "Lower Yuan" period, it must absolutely not be used. If unavoidable, stir-fry Bai Shao until carbonized and use 3 qian. Other herbs are prepared according to this method.
Song Verse: Pregnant woman's great anger opens the blood gate, her blood rushes directly into the fetal sac.
The fetal sac's connection links Heart and Kidney, blockage of Heart-Kidney pathway leads to miscarriage.
Yin Qi Gui Xue uses Bai Shao and Dang Gui, Bai Zhu, Mai Dong, Dan Pi, Jing Jie Sui.
Jiang Tan, Yu Jin, Xiang Fu, Gan Cao; decoct and take, Qi returns and Blood also returns.
