妊娠胎气本乎血气，胎不长者，亦惟血气之不足耳。故于受胎之后而漏血不止者有之，血不归胎也；妇人
中年血气衰败者有之，泉源日涸也；妇人多脾胃病者有之，仓廪薄则化源亏而冲任穷也；妇人多郁怒者有之，
肝气逆则血有不调，而胎失所养也。或以血气寒而不长者，阳气衰则生气少也；或以血热而不长者，火邪盛则
真阴损也。凡诸病此者，则宜补、宜固、宜温、宜清。但因其病而随机应之，则或以及期、或以过月，胎气渐
充，自无不长。惟是年迈血衰而然者，数在天矣，有非可以人力为也。
妇人有鬼胎之说，岂虚无之？鬼气果能袭人胞宫而遂得成形者乎？此不过由本妇之气质，盖或以邪思蓄
注，血随气结而不散，或以冲任滞逆，脉道壅瘀而不行，是皆内因之病，而必非外来之邪。盖即血 气瘕之
类耳。当即以 瘕之法治之，详见本条。此外如狐魅异类之遇者，则实有所受而又非鬼胎之谓，亦当于“ 瘕
类”求法下之。
又凡鬼胎之病，必以血气不足而兼凝滞者多有之。但见经候不调而预为调补，则必无是病。若其既病，则
亦当以调补元气为主，而继以去积之药，乃可也。然用补之外，而欲于补中兼行者，无如决津煎；欲去其滞而
不至猛峻者，无如通瘀煎；既加调补而欲直收其病者，则夺命丹、回生丹皆可酌用。或以当归红花煎浓汤送赤
金豆亦妙。

妊娠期间，胎气的形成根本在于血气。胎儿发育不良（胎不长），也是由于血气不足所致。因此，在受孕之后出现漏血不止的情况，是因为血液不能归附于胎元；中年妇女血气衰败的，是因为生命源泉日渐枯竭；妇女中多患脾胃病的，是因为脾胃虚弱则化源亏虚，导致冲任二脉气血穷竭；妇女中多情绪抑郁愤怒的，是因为肝气上逆导致血液运行不调，从而使胎儿失去滋养。有的因为血气寒凝而导致胎儿不长，这是因为阳气衰弱，生机减少；有的因为血热而导致胎儿不长，这是因为火邪旺盛损伤了真阴。凡是患有这些病症的，应当采取补益、固摄、温煦、清热的治疗方法。只要根据具体的病因随机应变，那么无论是到预产期还是过期未产，胎气逐渐充盈，自然没有不长大的道理。只有那些因年迈血衰而导致的，则是天数注定，不是人力所能改变的。
妇女中有“鬼胎”的说法，难道是虚无的吗？鬼气果真能侵袭人的胞宫并成形吗？这不过是源于妇女自身的体质状况，大概是由于邪念蓄积灌注，血液随着气机凝结而不散；或者是冲任二脉阻滞逆乱，脉道壅塞瘀滞而不行。这些都是内因引起的疾病，必定不是外来的邪气。这实际上就是血气瘕聚一类的病证。应当立即按照治疗瘕聚的方法来治疗，详见本条。此外，如遇到狐魅异类之类的事情，那确实是有所感受但又不是鬼胎，也应当在“瘕聚类”中寻找治法来攻下它。
另外，凡是鬼胎这类疾病，大多是因为血气不足兼有凝滞造成的。只要在月经失调时就预先进行调补，就一定不会得这种病。如果已经患病，也应当以调补元气为主，然后继之以消除积滞的药物，才可以治愈。然而，在使用补法之外，想要在补益的同时兼顾疏通的，没有比决津煎更好的；想要去除瘀滞而不至于猛烈峻烈的，没有比通瘀煎更好的；既加强调补又希望直接收效的，那么夺命丹、回生丹都可以酌情使用。或者用当归红花煎的浓汤送服赤金豆，效果也很好。

Pregnancy and fetal development are fundamentally rooted in Blood and Qi. Fetal growth retardation (Tai Bu Zhang) is solely due to a deficiency of Blood and Qi. Therefore, there are cases where bleeding persists after conception because the Blood fails to anchor the fetus; there are cases in middle-aged women where Blood and Qi decline because the source of life is gradually drying up; there are cases among women prone to Spleen and Stomach diseases because a weak Spleen and Stomach lead to a deficit in transformation sources, exhausting the Chong and Ren vessels; there are cases among women prone to depression and anger because Liver Qi rebellion causes irregular Blood flow, depriving the fetus of nourishment. Some have poor fetal growth due to cold in Blood and Qi, as Yang Qi deficiency leads to less vital energy; some have poor fetal growth due to heat in Blood, as excessive Fire pathogenic factors damage True Yin. For all such conditions, appropriate treatments include tonifying, consolidating, warming, and clearing. By addressing the specific pathology with flexible application, whether at term or post-term, as fetal Qi gradually fills, growth will naturally occur. Only when it is due to advanced age and blood decline is it a matter of destiny, beyond human intervention.
The concept of "Ghost Fetus" (Gui Tai) in women—could it be nonexistent? Can ghostly qi truly invade the uterus and take form? This is merely due to the woman's own constitution, perhaps caused by obsessive thoughts accumulating, causing Blood to knot with Qi without dispersing; or due to stagnation and rebellion in the Chong and Ren vessels, causing blockage and stasis in the meridians so that flow ceases. These are all internal pathological conditions, definitely not external pathogens. Essentially, this belongs to the category of Blood and Qi masses (Jia Ji). It should immediately be treated according to the methods for Jia Ji, detailed in the relevant section. Furthermore, encounters with supernatural entities like fox spirits, while real experiences, do not constitute Ghost Fetus; one should also seek treatment methods under the "Masses Category" to purge them.
Moreover, Ghost Fetus disease often arises from a combination of Blood and Qi deficiency with stagnation. If menstrual irregularities are addressed with preventive regulation and tonification beforehand, this disease will certainly not occur. If the disease has already manifested, treatment must primarily focus on regulating and tonifying Yuan Qi, followed by medications to eliminate accumulations. However, besides using tonification alone, if one wishes to combine tonification with unblocking, there is no better formula than Jue Jin Decoction (Decoction for Crossing the Ford); if one wishes to remove stagnation without being overly harsh, there is no better formula than Tong Yu Decoction (Decoction for Unblocking Stasis); if one seeks both strong tonification and direct therapeutic effect, then Duo Ming Dan (Life-Rescuing Pill) and Hui Sheng Dan (Return-to-Life Pill) can be used discretionarily. Alternatively, sending Chi Jin Dou (Golden Bean) with a concentrated decoction of Dang Gui Hong Hua Jian yields excellent results.
Jue Jin Decoction (See Menstrual Abdominal Pain)
Tong Yu Decoction (See Menstrual Abroad Pain)
Duo Ming Dan from *Liang Fang* (See *Fu Ren Gui Ancient Formulas*), treating Blood stasis entering the uterus, causing distension and difficulty in expulsion. Taking this medicine urgently causes the stasis to dissipate and the fetal membrane to descend. Note: This formula shares the efficacy of Hui Sheng Dan and is effective for expelling dead fetuses; it must include Dang Gui.
Prepared Fuzi (Cinnamon Twig Root, half tael), Ganshi (Dry Lacquer, crushed, stir-fried until smoke ceases), Mudanpi (Moutan Bark, each one tael).
Grind into fine powder. Separately, take one tael of Dahuang (Rhubarb) powder, add one sheng of good vinegar, and boil into a paste. Mix with the previous medicines, roll into pills the size of tung tree seeds, and swallow five to seven pills with warm wine. Another version includes one tael of Dang Gui.
Hui Sheng Dan (See *Fu Ren Gui Ancient Formulas*), treating various postpartum disorders in women, including retained lochia, pain from any excess pathogenic factors, dead fetus, and counterflow of Blood stasis.
Method for preparing Dahuang Paste: Use Sanmu (Sappan Wood) three taels and five bowls of river water, boil down to three bowls, strain and set aside. Honghua (Safflower) three taels, stir-fry until yellow, add one large pot of good wine, boil ten to twelve times, strain and set aside. Heidou (Black Soybean) three sheng, cook thoroughly, retain three bowls of juice, remove beans, dry the skins and grind into powder, set aside. Dahuang (Rhubarb) one jin, grind into powder, add eight bowls of good vinegar, boil into a paste. Then add the Honghua wine, Sanmu decoction, and Heidou juice, mix well, and boil again into a paste. Store in a basin for use. Roast the scorched residue in the pot until dry, grind into powder, and add together with the bean skin powder.
Renshen (Ginseng), Baizhu (Atractylodes Macrocephala Rhizome), Qingpi (Green Tangerine Peel), Mugua (Chaenomelis Fructus) (each three qian), Dang Gui (Angelica Sinensis Root), Chuanxiong (Ligusticum Wallichii Rhizome), Yuanhu (Corydalis Rhizome), Cangzhu (Atractylodes Lancea Rhizome), Xiangfu (Cyperi Rhizome, stir-fried with child's urine), Puhuang (Typha Pollen), Chifuling (Red Poria), Taoren (Peach Kernel Paste), Shudi (Rehmannia Glutinosa Root Prepared) (each one tael), Niuxi (Achyranthes Bidentata Root), Sanleng (Sparganium Rhizome), Shanzhuyu (Cornus Officinalis Fruit), Wulingzhi (Trogopterus Dung), Diyu (Sanguisorba Officinalis Root), Gancao (Licorice Root), Qianghuo (Notopterygium Root), Chenpi (Tangerine Peel), Baishao (White Peony Root) (each five qian), Liangjiang (Galangal Rhizome) (four qian), Wuyao (Litsea Petiolata Fruit) (two taels and a half), Muxiang (Vladimiria Root), Ruxiang (Frankincense), Moyao (Myrrh) (each one qian).
Grind all into powder. Use the previously prepared Dahuang paste to form pills the size of quail eggs, coat with gold foil. Take one pill at any time according to the syndrome, guided by a decoction.
Chi Jin Dou (See *Xin Fang Ba Zhen · Gong Zhen*), also known as Ba Xian Dan. Treating various types of stagnation and accumulation. Suitable for Blood coagulation and Qi stagnation causing pain and swelling, or hard parasitic accumulations. This pill removes disease rapidly and effectively, greatly surpassing agents like Xiaoshi (Mirabilite), Dahuang (Rhubarb), Sanleng (Sparganium), and E Zhu (Curcuma Phaeocaulis Rhizome) which excessively damage healthy Qi.
Badoushuang (Croton Seed Frost, peeled, oil slightly removed, one qian and a half), Sheng Fuzi (Raw Aconite Carleil, sliced, lightly stir-fried dry, two qian), Zaojiao (Gleditsia Sinensis Fruit, stir-fried until slightly scorched, two qian), Qingfen (Calomel, one qian), Dingxiang (Caryophylli Flos), Muxiang (Vladimiria Root), Tianzhuhuang (Calami Tuber) (each three qian), Zhusha (Cinnabar, two qian, used for coating).
Grind into powder. Soak steamed dough in vinegar to form pills the size of radish seeds, coat with Zhusha. To eliminate gradually, take five to seven pills per dose; to purge rapidly, take ten to twenty pills per dose. Guide with boiling water, herbal decoction, ginger, vinegar, tea, honey, Huixiang (Fennel Fruit), or Shijunzi (Quisqualis Indica Fruit) decoction. If diarrhea persists, drink one or two mouthfuls of cold water to stop it, as this medicine moves with heat and stops with cold. For treating Qi stagnation, Dampness stagnation, Excess stagnation, or Drum Distension, first cook red dates thoroughly, take about one qian of the flesh, mix with seven or eight pills (or ten to twenty for severe cases), mash together with the date flesh, and send down with hot liquor and a little white sugar.
