堕胎后荣卫损伤，腠理虚疏，未得平复，若起早当风取凉，即着于风。初止羸弱，或饮
食减少，气力不即平复。若风挟冷入腹内，搏于血，结成刺痛。若入肠胃，亦下痢。入经络
，或痹，或疼痛。若入太阳之经，则腰背强直成痉，或角弓反张，或口 僻，或缓弱不
随，或一边挛急。各随所伤处而成病也。
此谓妊娠之人羸瘦，或挟疾病，既不能养胎，兼害妊妇，故去之。
人处三才之间，禀五行之气，阳施阴化，故令有子。然五行虽复相生，而则柔刑杀，互
相害克。至于将产，则有日游、反支禁忌，若犯触之，或横致诸病。故产时坐卧产处，须顺
四时五行之气，故谓之产法也。
防运者，诸临产若触犯日游、反支诸所禁忌，则令血气不调理，而致运也。其运之状，
心烦闷，气欲绝是也，故须预以法术防之。
有产儿下，苦胞衣不落者，世谓之息胞。由产妇初时用力，比产儿出而体已疲顿，不能
更用气产胸，经停之间，外冷乘之，则血道痞涩，故胞久不出。弥须急以方药救治，不尔，
害于儿。所以尔者，胞系连儿脐，胞不出，则不得以时断脐浴洗，冷气伤儿，则成病也。
旧方胞衣久不出，恐损儿者，根据法截脐，而以物系其带一头。亦有产而看产人不用意慎
护，而挽牵甚，胞系断者，其胞上掩心，则毙人也。纵令不死，久则成病也。
堕胎之后，荣气与卫气受到损伤，腠理（皮肤纹理及汗孔）空虚疏松，身体尚未恢复平静。如果此时过早起身，迎风取凉，风邪就会侵入人体。起初仅表现为身体瘦弱，或者饮食减少，气力不能立即恢复。如果风邪夹带寒气进入腹内，与血液搏结，就会形成刺痛的症状。如果风邪进入肠胃，则会导致腹泻痢疾。如果风邪进入经络，或导致肢体麻木不仁（痹证），或引起疼痛。如果风邪侵入太阳经（足太阳膀胱经），则会出现腰背僵硬挺直而发展为痉病（以项背强直、四肢抽搐为特征的病证），或者出现角弓反张（身体向后弯曲如弓状）、口眼歪斜、半身软弱无力不能随意运动、或者一侧肢体拘挛紧急等症状。这些都是根据风邪所伤害的部位不同而形成的疾病。
这说的是妊娠期间妇女身体消瘦羸弱，或者兼有疾病，既不能滋养胎儿，又损害孕妇自身，所以应当终止妊娠（堕胎）。
人处于天、地、人三才之间，禀受五行之气，阳气施布，阴气化生，因此能够孕育子女。然而五行虽然相生，但也存在相克制约的关系，互相妨害克制。到了临产之时，就有“日游”、“反支”等禁忌日子，如果触犯这些禁忌，可能会导致各种疾病。所以在分娩时坐卧于产床，必须顺应四时五行之气，这就称为产法。
所谓“防运”，是指各位产妇在临产时如果触犯了“日游”、“反支”等各种禁忌，就会导致血气不调和，从而引发“运”症。这种“运”症的表现是心中烦闷，气息微弱几乎要断绝，所以必须预先用法术来预防它。
如果有婴儿已经生下，但痛苦于胎盘（胞衣）排不下来的情况，世人称之为“息胞”。这是因为产妇在刚开始生产时用力过猛，等到婴儿产出时身体已经极度疲劳，无法再使用力气推动胸部以下的宫缩，在这停顿的间隙，外面的寒气乘虚而入，导致血脉通道痞塞不通，所以胎盘久久不能排出。这时必须紧急用方药救治，否则会对婴儿造成伤害。之所以这样，是因为胎盘通过系带连接着婴儿的脐带，胎盘如果不出来，就不能及时剪断脐带并给婴儿洗澡清洁，寒气伤及婴儿，就会使婴儿生病。旧有的医方中，对于胎盘久出不下来、担心损伤婴儿的情况，按照方法剪断脐带，并用物体系住脐带的一端。也有在生产时，接生的人不用心谨慎护理，拉扯过于猛烈，导致胎盘系带断裂的，如果胎盘上移掩蔽心脏，就会导致产妇死亡。即使不死，久而久之也会变成疾病。
After abortion, the Ying (Nutrient) Qi and Wei (Defensive) Qi are damaged, the Couli (pores and interstices of the skin) become deficient and loose, and the body has not yet recovered. If one rises too early to face the wind and seek coolness, Wind pathogen will invade. Initially, it only manifests as emaciation and weakness, or reduced food intake, with strength not immediately recovering. If Wind carries Cold into the abdomen and clashes with Blood, forming stabbing pain. If it enters the Stomach and Intestines, it also causes dysentery. If it enters the meridians, it may cause Bi syndrome (obstruction causing numbness or pain) or pain. If it enters the Taiyang Meridian (Foot-Taiyang Bladder Meridian), it results in stiffness and straightening of the waist and back developing into Jing disease (spasm characterized by neck/back rigidity and limb convulsions), or opisthotonos (body bent backward like a bow), or facial paralysis (deviation of mouth and eye), or flaccid weakness and inability to move voluntarily, or spasms and tightness on one side. Diseases form according to the site injured by the pathogen.
This refers to pregnant women who are emaciated or complicated by diseases; since they cannot nourish the fetus and simultaneously harm the mother, termination is indicated.
Humans exist between Heaven, Earth, and Humanity, inheriting the Qi of the Five Elements. Yang exerts its influence and Yin transforms it, thus allowing conception. Although the Five Elements generate each other, they also restrain and kill each other through mutual conflict. At the time of delivery, there are taboos such as "Ri You" (Daily Traveling Deity) and "Fan Zhi" (Reverse Branch). If these are violated, various illnesses may arise. Therefore, when sitting or lying during labor, one must conform to the Qi of the Four Seasons and Five Elements; this is called the Method of Delivery.
The term "Fang Yun" (Preventing Yun) refers to: if parturients violate taboos like Ri You and Fan Zhi during labor, it causes disharmony of Qi and Blood, leading to Yun syndrome. The manifestation of Yun is mental restlessness and oppression, with breath nearly failing; thus, magical methods must be used in advance to prevent it.
When a child is born but suffers from the failure of the placenta (Baoyi) to expel, it is commonly called Xi Bao (Stagnant Placenta). This occurs because the mother exerted herself heavily at the beginning of labor; by the time the child is out, her body is exhausted and she cannot use Qi to push down from the chest/abdomen again. During this pause, external Cold attacks, causing blood vessels to become obstructed and sluggish, hence the placenta remains for a long time. It is urgent to treat with herbal formulas; otherwise, it harms the infant. The reason is that the placental cord connects to the infant's umbilical cord. If the placenta does not come out, the umbilical cord cannot be cut and the infant bathed in time. Cold Qi injuring the infant leads to illness. Old prescriptions for prolonged retention of the placenta fearing injury to the infant dictate cutting the umbilical cord according to method and tying one end of the cord with an object. Also, if attendants are careless during delivery and pull too forcefully, breaking the placental cord, if the placenta moves up to cover the Heart, it causes death. Even if not fatal, it becomes a disease over time.
