凡妊娠未满三月，形象未着男女，宜用方术转女成男，多验。特录。
法取明雄黄（一块，重两余者，）用绛囊盛之，佩于孕妇身左，更以弓弦同贮佩之。或萱花
同佩（名宜男草。）
又 常张弓弦于其父侧，悬弧以视母。
又 钺戈、斧斤，密置于床席之下，勿令人知，当诵诗书之声。
又 孕妇着夫衣冠，于井中左顾井内影三日，封并，半月方开，生男。
三个月足用白大川芎一个，研末三钱，空心温酒或艾汤调下，微动是。胎不动者，血阻也。
胎动时，头向左动者是男，头向右动者是女。诊左尺脉洪盛是男，右尺脉沉实是女。五月作
偶遣妊妇面南行，忽呼之，左 者男，右 者女。
夫半产堕胎之患，每至三月而落。盖妊娠三月名始胚，至此则血不流行，形象始化，未有定
仪，易于伤堕，皆由气血不充，肌体薄弱。有禀赋而致者，有劳损而致者，胎元虽成，而无以滋
养之故也。或因七情火炽，逼血妄行，或因行动跌磕致伤而堕，皆宜随证用药调理，最宜安静为
贵。盖胎元（说见胎前）仅得脐带系母腰肾，名紫河车蒂，甚微甚脆。有孕妇气血充足，胎元安
稳，饮食起居如常，忽然小产，实非产也。乃少年男妇，不谙事理，惟恣情欲， 褥妄为，致妇
蜷腰曲腹，忽断此蒂，瞬息母死胎亡，若此甚多，深可痛悯。
主方 （三个月服） 人参 黄 白术 条芩（各二钱） 当归身（一钱） 熟地 川
芎白芍（各七分） 陈皮（五分） 黄连
升麻 柴胡（各三分） 糯米八十一粒，水煎服。为丸亦可。
磐石散 因瘦而血虚有热，肥而气虚不实，少食体羸而致堕胎者。此方平和气血，补益脾
胃。有热倍芩，减砂仁，无热反之。
人参 黄 当归 川续断 熟地（各一钱） 白术（二钱） 川芎 白芍（各八分） 糯
米（一撮） 炙甘草（五分） 黄芩（一钱） 砂仁（五分）
上水钟半，煎七分，食远服。二、三、四月间日服。丸亦可。
凡怀孕未满三个月，胎儿的男女特征尚未显现时，适宜使用方术将女胎转为男胎，大多灵验。特此记录。
方法：取明雄黄（一块，重量在一两以上的），用红色丝袋装好，佩戴在孕妇身体左侧，再用弓弦一同装入佩戴。或者与萱花同佩（萱花名叫宜男草）。
又法：常在父亲身边常备弓弦，悬挂木弓来观察母亲。
又法：将钺、戈、斧、斤等兵器，秘密放置在床席之下，不要让人知道，应当诵读诗书的声音。
又法：孕妇穿着丈夫的衣帽，对着井中向左看井内的倒影三天，封存井口，半个月后才打开，生男孩。
满三个月时，用大白川芎一个，研成粉末三钱，空腹时用温酒或艾叶汤调服，微微胎动即为有效。如果胎不动，是血阻滞所致。
胎动时，头向左边动的是男孩，头向右边动的是女孩。诊察左尺脉洪大旺盛的是男孩，右尺脉沉实的是女孩。怀孕五个月时，偶然让孕妇面向南行走，突然呼喊她，向左回头的是男孩，向右回头的是女孩。
至于半产（小产）堕胎的祸患，往往在怀孕三个月时发生坠落。因为怀孕三个月名为“始胚”，到了这个时候气血运行不畅，形象开始变化，还没有固定的形态，容易受伤堕落，这都是由于气血不充足，肌体薄弱造成的。有因先天禀赋不足而导致的，有因劳累损伤而导致的，虽然胎元已经形成，却因为没有足够的滋养所致。也有因为七情过极化火，逼迫血液妄行，或者因为行动跌倒磕碰导致受伤而流产，都应当根据证候用药调理，最以安静为贵。因为胎元（说法见胎前章节）仅靠脐带系于母亲的腰肾，名叫紫河车蒂，非常微小脆弱。有的孕妇气血充足，胎元安稳，饮食起居如常，忽然小产，这实际上并非正常的生产。而是少年男女，不懂事理，放纵情欲，在褥被间妄为，导致妇女弯腰曲腹，忽然断绝此蒂，瞬息之间母亲死亡胎儿亡故，像这样的情况很多，深可痛惜怜悯。
主方（怀孕三个月服用）：人参、黄芪、白术、条芩（各二钱）、当归身（一钱）、熟地、川芎、白芍（各七分）、陈皮（五分）、黄连、升麻、柴胡（各三分），糯米八十一粒，水煎服。制成丸药也可以。
磐石散：适用于因瘦弱而血虚有热，肥胖而气虚不实，食欲少身体消瘦而导致堕胎的情况。此方平和气血，补益脾胃。有热的加倍黄芩，减少砂仁；无热的则相反。
配方：人参、黄芪、当归、川续断、熟地（各一钱）、白术（二钱）、川芎、白芍（各八分）、糯米（一撮）、炙甘草（五分）、黄芩（一钱）、砂仁（五分）。
以上药材用水半钟，煎至七分，饭后服用。第二、三、四个月期间隔日服用。制成丸药也可以。
Whenever pregnancy is less than three months, and the male or female characteristics of the fetus have not yet manifested, it is appropriate to use methods to transform a female fetus into a male one; this is often effective. It is recorded here.
Method: Take Ming Xionghuang (Realgar, 明雄黄) (a piece weighing more than one liang), place it in a crimson silk bag, wear it on the left side of the pregnant woman's body, and store it together with a bowstring for wearing. Alternatively, wear it together with Xuanhua (Daylily, 萱花) (known as Yinancao, "Suitable-for-Boy Grass").
Another method: Keep a bowstring always by the father's side, and hang a wooden bow to observe the mother.
Another method: Secretly place Yuege (Yue and Ge, ancient weapons), Fuxin (Axe and Hatchet) under the bed mats, without letting others know, while reciting poetry and books.
Another method: The pregnant woman wears her husband's clothes and hat, looks to the left at her reflection in the well for three days, seal the well mouth, and open it after half a month; this results in a male birth.
At three full months, take one large Chuanxiong (Rhizoma Chuanxiong), grind it into powder, take three qian, mix with warm wine or Mugwort Decoction on an empty stomach; slight fetal movement indicates efficacy. If there is no fetal movement, it is due to blood obstruction.
When fetal movement occurs, if the head moves to the left, it is a boy; if to the right, it is a girl. Palpating the Left Chi pulse (Left Radial Pulse at the Cinnabar position), if surging and abundant, indicates a boy; if the Right Chi pulse is deep and solid, it indicates a girl. At five months, occasionally have the pregnant woman walk facing south, suddenly call out to her; if she turns her head to the left, it is a boy; if to the right, it is a girl.
Regarding the misfortune of spontaneous abortion (Ban Chan, 半产) or miscarriage, it often occurs at three months of pregnancy. This is because at three months, the stage is called "Shi Pei" (Initial Embryo); at this point, blood circulation is not smooth, and the form begins to transform, lacking a fixed structure, making it prone to injury and falling. This is all due to insufficient Qi and Blood, and weak physique. Some are caused by congenital endowment deficiency, some by labor and damage. Although the Tai Yuan (Fetal Root, 胎元) has formed, it lacks nourishment. Others may be caused by excessive Seven Emotions transforming into fire, forcing blood to flow recklessly, or by physical trauma from falls and bumps leading to miscarriage. In all cases, medication should be adjusted according to the syndrome, with tranquility being most valuable. The Tai Yuan (see Pre-natal section) is attached to the mother's waist and Kidneys only by the umbilical cord, known as Ziheche Di (Placenta Stalk), which is very minute and fragile. Some pregnant women have sufficient Qi and Blood, stable Tai Yuan, and normal diet and起居, yet suddenly suffer a miscarriage; this is actually not childbirth. Rather, young men and women, ignorant of propriety, indulge in lust, acting recklessly in bed, causing the woman to curl her waist and bend her abdomen, suddenly severing this stalk. In an instant, the mother dies and the fetus perishes. Such cases are numerous and deeply pitiable.
