《病源论》云∶有产儿出而胞不落者，世谓之息胞。由产出而体疲，不能更用气，胞经
停之间外冷气乘之，则血道涩，故胞不出。
若挽其胞系断者，其胞上则毙人。
《产经》云∶（胞衣不出时，吞之立下，大吉。）
又方∶以水煮弓弦，令少少沸，饮之一升许。
又方∶多服猪肪。
《陶景本草注》云∶吞胡麻油少少。
又方∶取弓弩弦缚腰。
《葛氏方》云∶月水布烧末，以服少少。
又方∶末皂荚，纳鼻中得嚏，即下。
又方∶解发刺喉中，令得呕之，良。
《僧深方》云∶水银服如小豆二枚。
又方∶取夫单衣若巾，覆井立出。
《短剧方》云∶小麦，小豆，合煮汁饮，立出。
又方∶井中土如梧子大吞之。
《千金方》云∶服蒲黄如枣大者。
又方∶男吞小豆七枚，女吞十四枚。（《集验方》同。）
《集验方》云∶牛膝半斤，葵子三升，切，以水七升，煮取三升，分三服。（《医门方》
同之。）
《龙门方》云∶取灶中黄土末，着脐中。（今按∶《广济方》三指撮水服之。）
《产经》云∶凡欲藏胞衣，必先以清水好洗子胞，令清洁。以新瓦瓮，其盖亦新，毕乃
以真绛缯裹胞讫，取子贡钱五枚，置瓮底中罗烈，令文上向。乃已取所裹胞盛纳瓮中以盖覆
之，周密泥封，勿令入诸虫畜禽兽得食之，毕，按随月图以阳人使理之，掘深三尺二寸，坚
筑之，不欲令复发故耳。能顺从此法者，令儿长生，鲜洁美好，方高心善，圣智富贵也。且
以欲令儿有父才者，以新笔一柄着胞上藏之，大吉。此黄帝百二十占中秘文也。且藏胞之人
当得令名佳士者，则令儿辨慧多智，有令名美才，终始无病，富贵长寿矣。
又云∶一法先以水洗胞，令清洁讫，复用清酒洗胞，以新瓦瓮盛胞，取鸡雏一枚，以布
若缯缠雏置胞上，以瓦盖其口埋之。按十二月图于算多上藏之吉。其地向阳之处，深无过三
尺，坚筑之，勿令发也，大吉。男用雄雏。女用雌雏。（一说云∶如来云∶我不杀生，故得
寿长，何杀生求寿命？故不疏之。）
又云∶数数失子，藏胞衣法∶昔禹于雷泽之上，有一妇人悲哭而来，禹问其由，答曰∶
外家数生子而皆夭死，一无生在，故哀哭也。禹教此法，子皆长寿，无夭失也。取产胞衣善择
去草尘洗之清，作一土人，生儿男者作男像，生儿女者作女像，以绛衣裹土人。先以三钱置
新瓮中已，取土人着钱上，复取子胞置钱上，以盖新瓯，令周密封泥之。按算多地上，使儿
公自掘埋之，毕，祝曰∶一钱为汝领地主，一钱为汝寿领算，一钱为汝领口食，讫，以左足
蹈之。坚筑如上法。（今按∶后条儿公者儿父也。）
《诸病源候论》说：有婴儿出生后，胞衣不排出的情况，世人称之为“息胞”。这是因为分娩后身体疲惫，无法再用力，导致胞脉停滞，此时外界的冷气乘虚而入，致使血行涩滞，所以胞衣不能排出。
如果强行拉扯脐带导致断裂，胞衣上缩会危及产妇生命。
《产经》说：“（在胞衣不出时，吞服此药可立即排出，大吉大利。）”
另一个方子：用水煮弓弦，使其微微沸腾，饮用约一升。
另一个方子：多服用猪油。
《陶弘景本草注》说：少量吞服胡麻油。
另一个方子：取弓弩的弦绑在腰间。
《葛氏方》说：将月经布烧成灰末，少量服用。
另一个方子：将皂荚研成粉末，纳入鼻中引起喷嚏，胞衣即可下行。
另一个方子：解开头发刺入喉咙，引发呕吐，效果良好。
《僧深方》说：服用如水银如两粒小豆大小的剂量。
另一个方子：取丈夫的单衣或手巾，覆盖在井口，胞衣即可立出。
《短剧方》说：将小麦、赤小豆合在一起煮汁饮用，胞衣立即排出。
另一个方子：取井底泥土，如梧桐子大小吞服。
《千金方》说：服用蒲黄，量如枣大。
另一个方子：男孩吞服七粒小豆，女孩吞服十四粒。（《集验方》与此相同。）
《集验方》说：牛膝半斤，冬葵子三升，切碎，用水七升，煮取三升，分三次服用。（《医门方》与此相同。）
《龙门方》说：取灶中的黄土末，置于脐中。（今按：《广济方》是三指撮量的水送服。）
《产经》说：凡是想要收藏胞衣，必须先用清水仔细清洗子胞，使其清洁。使用新的瓦瓮，盖子也要新的，完成后用真红色的丝绸包裹好胞衣，取五枚子贡钱放在瓮底的罗网上，使钱币文字朝上。然后将被包裹的胞衣放入瓮中，盖上盖子，用泥严密密封，不要让各种虫畜禽兽吃到它。最后，按照随月图（按月令变化的禁忌图），让阳人（男性）进行理治，挖掘三尺二寸深的坑，夯实土壤，不希望再次翻动。能够顺从此法的人，孩子会长生，洁净美好，心胸高尚善良，具有圣智和富贵。况且如果想要让孩子具备父亲的才华，可以将一支新笔放在胞衣上一起收藏，大吉。这是黄帝百二十占中的秘文。而且收藏胞衣的人应当选择有名望、品德良好的士人，这样会使孩子聪慧多智，拥有美好的名声和才华，始终无病，富贵长寿。
又说：一种方法是先用水清洗胞衣，使其清洁后，再用清酒清洗胞衣，用新的瓦瓮盛放胞衣，取一只小鸡雏，用布或丝绸缠绕鸡雏放在胞衣上，用瓦片盖住瓮口埋藏起来。按照十二月图，在算多（吉位）处收藏为吉。地点选在向阳之处，深度不超过三尺，夯实土壤，不要挖开，大吉。男孩用雄鸡雏，女孩用雌鸡雏。（另一种说法认为：如来佛说：我不杀生，所以得长寿，为何要杀生求寿命？因此不予采纳。）
又说：多次流产失子的，收藏胞衣的方法：从前大禹在雷泽之上，遇到一位妇人悲伤哭泣而来，大禹询问原因，妇人回答说：“娘家多次生子都夭折死了，没有一个活下来的，所以哀伤哭泣。”大禹教给她这个方法，孩子都长寿，没有夭折失落的。选取产下的胞衣，仔细去除草尘清洗干净，做一个土人偶，生男孩就做男像，生女孩就做女像，用红色衣服包裹土人偶。先在新的瓮中放三枚钱，将土人偶放在钱上，再把胞衣放在钱上，用新的碗盖住，用泥严密密封。在算多地上，让孩子的父亲亲自挖掘埋藏，完毕后祝祷说：“一枚钱作为你的土地主，一枚钱作为你的寿命算数，一枚钱作为你的口粮。”完毕，用左脚踩踏。夯实土壤如同上述方法。（今按：后条文中提到的“儿公”即孩子的父亲。）
According to the *Zhu Bing Yuan Hou Lun* (Treatise on the Pathogenesis and Manifestations of All Diseases), there are cases where the placenta is not expelled after the birth of the infant, a condition known in common parlance as "Xi Bao" (Stagnant Placenta). This occurs because the mother's body is exhausted from delivery and unable to exert further effort. The meridians of the uterus stagnate, allowing external cold qi to invade. Consequently, the blood channels become obstructed, preventing the expulsion of the placenta.
If the umbilical cord is forcibly pulled and severed, the retraction of the placenta upwards can endanger the mother's life.
The *Chan Jing* (Classic of Childbirth) states: "(When the placenta fails to descend, swallowing this will cause it to come down immediately, bringing great auspiciousness.)"
Another prescription: Boil bowstrings in water until they simmer slightly, and drink approximately one sheng.
Another prescription: Consume large amounts of lard.
*Taohongjing Bencao Zhu* (Commentary on Materia Medica by Tao Hongjing) states: Swallow a small amount of sesame oil.
Another prescription: Tie a bowstring around the waist.
The *Ge Shi Fang* (Prescriptions of Ge) states: Burn menstrual cloth into ash and take a small amount orally.
Another prescription: Grind gleditsia sinensis seed pods into powder, insufflate into the nose to induce sneezing, which will cause the placenta to descend.
Another prescription: Untie hair and insert it into the throat to induce vomiting; this is effective.
The *Seng Shen Fang* (Prescriptions of Monk Shen) states: Take mercury equivalent to two small beans in size.
Another prescription: Place a husband's single-layer garment or handkerchief over a well mouth; the placenta will emerge immediately.
The *Duan Ju Fang* (Short Drama Prescriptions) states: Decoct wheat and adzuki beans together, drink the juice, and the placenta will be expelled immediately.
Another prescription: Swallow clods of earth from a well bottom, sized like a wutong seed.
The *Qian Jin Fang* (Prescriptions Worth a Thousand Gold) states: Take rhizoma cyperi powder (Puhuang), sized like a date.
Another prescription: Males swallow seven adzuki beans; females swallow fourteen. (This is consistent with the *Ji Yan Fang*.)
The *Ji Yan Fang* (Verified Prescriptions) states: Use half a jin of achyranthes bidentata root (Niuxi) and three sheng of okra seeds (Kuizi). Chop them, decoct in seven sheng of water to obtain three sheng of liquid, and divide into three doses. (This is consistent with the *Yi Men Fang*.)
The *Long Men Fang* (Dragon Gate Prescriptions) states: Take yellow earth powder from a stove and apply it to the navel. (Note: The *Guang Ji Fang* suggests taking three finger-pinches with water.)
The *Chan Jing* states: Whenever one wishes to inter the placenta, one must first wash the uterine membrane thoroughly with clean water until it is pristine. Use a new clay urn with a new lid. Afterward, wrap the placenta completely in genuine crimson silk. Place five Zigong coins at the bottom of the urn on a sieve, ensuring the inscriptions face upward. Then place the wrapped placenta into the urn, cover it, seal it tightly with mud to prevent any insects or animals from accessing it. Finally, following the Monthly Diagrams (taboo charts based on lunar months), have a male practitioner perform the ritual. Dig a pit three chi and two cun deep, compact the soil firmly to prevent future disturbance. Those who follow this method will ensure their child lives long, remains pure and beautiful, possesses a noble heart and virtuous character, and attains sage-like wisdom and wealth. Furthermore, if one desires the child to inherit the father's talents, place a new brush upon the placenta before interment for great auspiciousness. This is a secret text from the Hundred and Twenty Divinations of the Yellow Emperor. Moreover, the person entrusted with interring the placenta should be a reputable and virtuous scholar; this will endow the child with discernment, wisdom, a good reputation, and talent, ensuring lifelong health, wealth, and longevity.
It also states: One method involves washing the placenta with water until clean, then rinsing it with clear wine. Place the placenta in a new clay urn. Take one chick, wrap it in cloth or silk, place it on top of the placenta, cover the urn with a tile, and bury it. Inter it in an auspicious position according to the Twelve-Month Diagram. Choose a sunny location, no deeper than three chi, compact the soil firmly, and do not reopen it; this brings great auspiciousness. Use a male chick for a boy and a female chick for a girl. (Another view argues: As the Tathagata said, 'I do not kill living beings, thus I attain longevity. Why kill to seek longevity?' Therefore, this practice is rejected.)
It also states: For those who frequently suffer miscarriages, the method for interring the placenta is as follows: In ancient times, while at Leize, Yu the Great encountered a woman weeping bitterly. When asked why, she replied that her family had lost many children to premature death, leaving none alive, hence her grief. Yu taught her this method, and all subsequent children lived long without premature loss. Select the delivered placenta, carefully remove grass and dust, and wash it clean. Mold a clay figurine; if a boy was born, make a male figure; if a girl, a female figure. Wrap the figurine in red clothing. First, place three coins in a new urn. Place the clay figurine on the coins, then place the placenta on the coins. Cover with a new bowl and seal tightly with mud. On an auspicious spot, let the child's father dig and bury it personally. Upon completion, recite the incantation: "One coin serves as your lord of the land, one coin governs your lifespan, one coin provides for your sustenance." Then, stomp on the grave with the left foot. Compact the soil as described above. (Note: In later texts, "Er Gong" refers to the child's father.)
