气血充实胎自安，冲任虚弱损胎元。暴怒房劳伤肝肾，疾病相干跌扑颠。五月成形名小产，未成形象
堕胎言。无故至期数小产，须慎胎为欲火煎。
【注】孕妇气血充足，形体壮实，则胎气安固。若冲、任二经虚损，则胎不成实。或
因暴怒伤肝，房劳伤肾，则胎气不固，易致不安；或受孕之后，患生他疾，干犯胎气，致
胎不安者亦有之；或因跌扑筑磕，从高坠下，以致伤胎、堕胎者亦有之。然小产、堕胎，亦
自有别∶五、七月已成形象者，名为小产；三月未成形象者，谓之堕胎。以上小产、堕胎
皆出有因。若怀胎三、五、七月，无故而胎自堕，至下次受孕亦复如是，数数堕胎，则
谓之滑胎。多因房劳太过，欲火煎熬，其胎因而不安，不可不慎者也。

When Qi and Blood are abundant, the fetus remains secure naturally; when the Chong (Penetrating) and Ren (Conception) vessels are deficient, the fetal origin is damaged. Sudden anger or excessive sexual activity damages the Liver and Kidney; diseases interfering with the body or falls and blows also cause insecurity. Miscarriage at five months when the fetus has formed is termed "small birth" (Xiao Chan); abortion before formation is termed "falling of the fetus" (Duo Tai). If miscarriages occur repeatedly at expected intervals without obvious cause, one must exercise caution, as this is often due to the simmering of desire fire.
[Note] If a pregnant woman has sufficient Qi and Blood and a robust physique, the fetal Qi will be stable. If the Chong and Ren meridians are deficient, the fetus cannot develop fully. Alternatively, sudden anger may damage the Liver, and sexual fatigue may damage the Kidney, causing unstable fetal Qi and leading to insecurity; or after conception, contracting other illnesses may interfere with fetal Qi, causing insecurity; or falls, collisions, and jumping from heights may injure the fetus or cause abortion. However, there is a distinction between small birth and falling of the fetus: when the fetus has taken shape at five or seven months, it is called small birth; when it has not taken shape at three months, it is called falling of the fetus. The aforementioned cases of small birth and falling of the fetus all have specific causes. If the fetus spontaneously aborts at three, five, or seven months of pregnancy without cause, and this recurs in subsequent pregnancies, frequently resulting in abortion, it is termed "slippery fetus" (Hua Tai). This is mostly due to excessive sexual activity and the simmering of desire fire, which makes the fetus insecure; thus, caution is essential.

If fetal injury causes abdominal pain without bleeding, use Shengyu Decoction supplemented with Duzhong (Eucommia Bark), Xuduan (Dipsacus Root), and Sharen (Amomum Fruit) to stabilize it. If there is bleeding accompanied by abdominal pain, use Foshou Powder supplemented with Ejiao (Donkey-hide Gelatin), Qiai (Artemisia Argyi Leaf), Duzhong (Eucommia Bark), Xuduan (Dipsacus Root), Baizhu (Atractylodes Macrocephala Rhizome), and Huangqin (Scutellaria Root) to stabilize it. If maternal illness threatens the fetus and induces impending abortion, use Shisheng San, which is Shiquan Dabu Decoction (Ten Great Tonifying Decoction) minus Fuling (Poria) and Rougui (Cinnamon Bark), plus Xuduan (Dipsacus Root) and Sharen (Amomum Fruit). If fetal injury from falls or collisions threatens abortion, administer Yimu Wan (Motherwort Pill) washed down with Xiongtang (Ligusticum Decoction, composed of Chuanxiong and Danggui). If sudden anger or sexual fatigue damages the Liver and Kidney, causing fetal restlessness, treat with Xiaoyao San (Free and Easy Wanderer Powder) and Dihuang Tang (Rehmannia Decoction).
