（兼记难产胎衣不下方）
古人论胎在子宫，分经轮养∶一月肝经养，二月胆经养，三月心经养，四月三焦养，五
月脾
经交代，胆经交棒，此论实在无情无理。儿在母腹，全赖母血而成，一言可了，何必图取虚
名，故作欺人之论。又如子啼门云∶儿在母腹，口含脐带疙瘩，吮血养生。请问初结胎无口
时，又以何物吮血养生？既不明白，何不归而谋诸妇，访问收生婆，访问的确再下笔，断不
致遗笑后人。岂知结胎一月之内，并无胎衣。一月后，两月内，始生胎衣。胎衣既成。儿体
已定。胎衣分两段，一段浓，是双层，其内盛血；一段薄，是单层，其内存胎。浓薄之间，
夹缝中长一管，名曰脐带，下连儿脐。母血入胎衣内盛血处，转入脐带，长脏腑肢体，周身
齐长，并非先长某脏，后长某腑。一月小产者，并无胎衣；两月小产者，有胎衣，形如秤锤
，上小下大，不过是三指长短；三月小产者，耳目口鼻俱备，惟手足有拳不分指；至月足临
生时，儿蹬破胎衣，头转向下而生，胎衣随胎而下，胎衣上之血，随胎衣而下，此其长也。
最关紧要是难产，古人原有开骨散，服之有效者，有不效者，其方总论活血开骨，不重用力
劳乏。佘每用开骨散，重加黄 ，不过一时胎即下。至胎衣不下，古人原有没竭散，始而用
之，有效与不效，继而加倍用之，胎衣立下。药味要紧，分量更要紧。

This is the premier formula for promoting conception and calming the fetus.
(Also recorded: Difficult labor and retained placenta)
Ancients discussed fetal development in the uterus, claiming nourishment by meridians in rotation: The first month is nourished by the Liver Meridian, the second by the Gallbladder Meridian, the third by the Heart Meridian, the fourth by the San Jiao, the fifth by the Spleen taking over from the Gallbladder. This theory is truly heartless and unreasonable. The infant in the maternal abdomen is entirely formed relying on maternal blood; this can be explained in one sentence. Why seek empty fame and deliberately make deceptive arguments? Furthermore, the "Zi Ti Men" (Fetal Crying Gate) states: The infant in the womb holds the umbilical cord nodule in its mouth and sucks blood to sustain life. I ask, when the embryo is just formed and has no mouth, what does it suck blood from to sustain life? Since you do not understand, why not return home to consult women, visit midwives, inquire about the exact facts before writing? You would certainly not leave yourself open to ridicule by later generations. Who knew that within the first month of conception, there is no placenta. After one month but within two months, the placenta begins to form. Once the placenta is formed, the fetal body is determined. The placenta is divided into two sections: one thick, double-layered, containing blood inside; one thin, single-layered, containing the fetus inside. Between the thick and thin parts, a tube grows in the crevice, named the Umbilical Cord, connecting downwards to the infant's navel. Maternal blood enters the blood-containing area inside the placenta, transfers into the umbilical cord, nourishing the zang-fu organs and limbs, growing uniformly throughout the body, rather than growing certain zang organs first and fu organs later. In a miscarriage at one month, there is no placenta; in a miscarriage at two months, there is a placenta, shaped like a steelyard weight, small at the top and large at the bottom, only about three finger-widths long; in a miscarriage at three months, the ears, eyes, mouth, and nose are all complete, only the hands are clenched fists with indistinct fingers; until full term near delivery, the infant kicks through the placenta, turns the head downward to be born, and the placenta follows the fetus out, with the blood on the placenta draining down with it. This is the process of growth.
The most critical issue is difficult labor. The ancients originally had Kai Gu San (Bone-Opening Powder); some found it effective, others did not. The general principle of the formula is to invigorate blood and open the bones, without emphasizing physical exertion or fatigue. Whenever I use Kai Gu San, adding a heavy dose of Huang Qi (Astragalus Root), the fetus is delivered within a short time (one shichen). As for retained placenta, the ancients originally had Mo Jie San. Initially using it, results were mixed (effective or ineffective); subsequently doubling the dosage, the placenta was expelled immediately. The choice of herbs is important, but the dosage is even more important.
