妇人有怀妊，终年不产，面色黄瘦，腹如斗大，肌肤消削，常至二、三年未生
者，此鬼胎也。或入神庙山林，起交感之念，皆能召祟成胎。幸其人不至淫荡，见
祟惊惶，遇合愧恧则鬼祟不能久恋，一交媾而去，然而淫气妖氛已结于腹，遂成
鬼胎。其先人尚未觉，迨后渐渐腹大。盖人身之气血不行，内外相包，一如怀胎之
兆，有似血臌之形，其实非胎非臌也。治法必用逐秽之药为主。但人至怀胎数年，
即非鬼胎，其气血必衰，况非真妊，则邪气甚旺，正不敌邪，虚弱可知，乌可以迅
利之药竟用祛荡乎。自必从补中逐之为得。方用荡鬼汤∶
雷丸（三钱） 大黄（一两） 红花（三钱） 枳壳（一钱） 浓朴（一钱） 桃仁（二十粒） 当归（一两）
人参（一两） 牛膝（三钱） 丹皮（三钱） 水煎服。一剂腹必大鸣，泻出恶物半桶，再服二煎，又
泻恶物而愈，断不可用三剂也。
此方用雷丸以祛秽，又得大黄之扫除，佐之红花、浓朴等药，皆善行善攻之品，
亦何邪能留于腹中，自然尽情逐下。然用参、归以补气血，则邪去而正又不伤，否
则单用雷丸、大黄以迅下之，必有血崩气脱之害矣。倘或自知鬼胎，如室女寡妇之
人，一旦成形，虽邪气甚盛，而真气未漓，可用岐天师新传红黄霹雳散∶红花半斤，
大黄五钱，雷丸三钱，水煎服，亦能下胎。然未免过伤血气，不若荡鬼汤，有益无
损之更佳也。亦在人斟酌而善用之耳。
用追祟丹亦神效。
大黄（五钱） 枳实（三钱） 丹皮（一两） 红花（半斤） 附子（二钱） 当归尾（一两）
人参（五钱） 牛膝（五钱） 麝香（一钱） 鳖甲（一两） 半夏（三钱） 南星（三钱） 桃仁（十四粒）
水煎服。一剂而胎破矣，不须二剂。泻出恶物之后，单用当归三
两，红花一两，水煎服。自然败血净而新血生也。连用四剂，自庆安然。
Women who conceive but do not deliver for a full year, presenting with a sallow and emaciated complexion, an abdomen enlarged to the size of a dou (a traditional unit of volume), wasted skin and muscles, and often failing to give birth for two or three years, are suffering from "Ghost Fetus" (Guǐ Tāi). Entering temples or mountains and forests and generating thoughts of sexual union can all attract malevolent spirits to form a fetus. Fortunately, if the individual is not excessively licentious, and upon seeing the spirit feels panic, and upon encountering coitus feels shame and embarrassment, the malevolent spirit cannot linger long; after one act of intercourse, it departs. However, the lascivious qi and demonic aura have already condensed in the abdomen, thus forming the Ghost Fetus. Initially, people do not notice, but later the abdomen gradually enlarges. This is because the qi and blood in the human body fail to circulate properly, wrapping internally and externally, resembling the signs of pregnancy, with a shape similar to Blood Distension (Xuè Gǔ - a condition characterized by abdominal distension like a drum, yellowish skin, and visible collateral vessels), yet it is neither a fetus nor distension. The treatment method must primarily employ drugs that purge filth. However, when a person has carried a fetus for several years, even if it were not a Ghost Fetus, their qi and blood would inevitably be depleted. Moreover, since it is not a true pregnancy, the pathogenic qi is extremely vigorous, and the healthy qi is unable to resist it, making the debility obvious. How could one use swift and purgative drugs directly to dispel and cleanse? It is necessary to adopt a strategy of tonifying while purging. The prescription used is Dangui Tang (Ghost-Scouring Decoction):
*Pleurotus tuber* (Sanqian, 3 qian) *Rhei Radix et Rhizoma* (Dahuang, 1 liang) *Carthami Flos* (Honghua, 3 qian) *Aurantii Fructus Immaturus* (Zhiqiao, 1 qian) *Magnoliae Officinalis Cortex* (Houpo, 1 qian) *Persicae Semen* (Taoren, 20 grains) *Angelicae Sinensis Radix* (Danggui, 1 liang)
*Ginseng Radix* (Renshen, 1 liang) *Achyranthis Bidentatae Radix* (Niuxi, 3 qian) *Moutan Cortex* (Danpi, 3 qian) Decoct in water and take orally. After one dose, the abdomen will certainly rumble loudly, evacuating half a bucket of foul matter. Take the second decoction again, evacuate more foul matter, and recover. Do not use a third dose under any circumstances.
This formula uses *Pleurotus tuber* to remove filth, aided by the sweeping action of *Rhei Radix et Rhizoma*, assisted by herbs such as *Carthami Flos* and *Magnoliae Officinalis Cortex*, all of which are potent agents for promoting circulation and attacking stagnation. Thus, what pathogenic factor could remain in the abdomen? Naturally, it will be thoroughly expelled. However, by using *Ginseng Radix* and *Angelicae Sinensis Radix* to tonify qi and blood, the pathogens are removed without injuring the healthy qi. Otherwise, using only *Pleurotus tuber* and *Rhei Radix et Rhizoma* for rapid purgation would inevitably lead to the harm of hemorrhage and qi collapse. If individuals are aware they have a Ghost Fetus, such as unmarried women or widows, once the formation occurs, although the pathogenic qi is very strong, the true qi remains intact. In such cases, the newly transmitted Honghuang Pilei San (Red-Yellow Thunderbolt Powder) by Master Qi may be used: *Carthami Flos* (8 liang), *Rhei Radix et Rhizoma* (5 qian), *Pleurotus tuber* (3 qian), decocted in water and taken orally, which can also expel the fetus. However, this inevitably causes excessive damage to blood and qi. It is not as superior as Dangui Tang, which benefits without causing harm. Ultimately, it depends on careful consideration and appropriate usage.
Using Zhuisui Dan (Spirit-Chasing Pill) is also miraculous.
*Rhei Radix et Rhizoma* (5 qian) *Immature Bitter Orange Fruit* (Zhishi, 3 qian) *Moutan Cortex* (1 liang) *Carthami Flos* (8 liang) *Aconiti Lateralis Radix Praeparata* (Fuzi, 2 qian) *Angelicae Sinensis Radix Cauda* (Dangguiwei, 1 liang)
*Ginseng Radix* (5 qian) *Achyranthis Bidentatae Radix* (5 qian) *Moschus* (Shexiang, 1 qian) *Trionycis Carapax et Plastrum* (Biejia, 1 liang) *Pinelliae Tuber* (Banxia, 3 qian) *Arisaematis Rhizoma* (Nanxing, 3 qian) *Persicae Semen* (14 grains)
Decoct in water and take orally. After one dose, the fetus ruptures; a second dose is unnecessary. After evacuating the foul matter, use only *Angelicae Sinensis Radix* (3 liang) and *Carthami Flos* (1 liang), decocted in water and taken orally. Naturally, the stale blood will be cleared, and new blood generated. Use continuously for four doses, and one can rejoice in safety and well-being.
