〔大〕夫妊娠不长者，因有宿疾，或因失调，以致脏腑衰损，气血虚弱而胎不长也。
当治其疾疚，益其气血，则胎自长矣。
〔薛〕前证更当察其经络，审其所因而治之。一妊妇胎六月，体倦懒食，面黄晡
热而胎不长，因劳欲坠。此脾气不足也，用八珍汤倍加参、术、茯苓，三十余剂，脾胃
渐健，胎安而长矣。一妊妇因怒寒热往来，内热晡热，胁痛呕吐，胎至八月而不长。此
因肝脾郁怒所致，用六君加柴胡、山栀、枳壳、紫苏、桔梗，病愈而胎亦长矣。

【大】如果妊娠期间胎儿发育迟缓，是因为患者原本就有旧疾，或者因为调养不当，导致脏腑功能衰退损伤，气血虚弱，从而使胎儿不能正常生长。
应当治疗其原有的疾病，补益其气血，那么胎儿自然就会生长发育了。
【薛】上述症状更应当观察其经络情况，审查致病原因并据此进行治疗。有一位孕妇怀孕六个月，身体疲倦、食欲不振，面色萎黄，傍晚时分发热且胎儿发育迟缓，这是因为劳累和房事过度导致胎气下坠。这是脾气不足的表现，使用八珍汤（Bazhen Tang, Eight-Treasure Decoction）并加倍人参、白术、茯苓的用量，服用三十多剂后，脾胃功能逐渐强健，胎气安定，胎儿也正常发育了。还有一位孕妇因愤怒导致寒热往来，体内发热、傍晚发热，胁肋疼痛、呕吐，怀孕至八月时胎儿仍不发育。这是由于肝脾郁结愤怒所致，使用六君子汤（Liujunzi Tang, Six-Gentlemen Decoction）加入柴胡、山栀、枳壳、紫苏、桔梗，病愈后胎儿也随之发育了。

[Da] If the fetus fails to grow during pregnancy, it is due to pre-existing chronic diseases or improper regulation, leading to the decline and damage of Zang-Fu organs, and deficiency of Qi and Blood, thereby preventing normal fetal growth.
The treatment should focus on curing the underlying disease and tonifying Qi and Blood, after which the fetus will naturally grow.
[Xue] In the aforementioned conditions, one must further examine the meridians and investigate the etiology to guide treatment. One pregnant woman at six months gestation presented with fatigue, poor appetite, sallow complexion, afternoon fever, and fetal growth retardation, caused by overexertion and sexual indulgence leading to sinking of fetal Qi. This indicated Spleen Qi deficiency; she was treated with Bazhen Tang (Eight-Treasure Decoction) with increased doses of Renshen (Ginseng), Baizhu (Atractylodes Macrocephala Rhizome), and Fuling (Poria), administered for over thirty doses. Her Spleen and Stomach function gradually strengthened, fetal stability was restored, and the fetus grew normally. Another pregnant woman presented with alternating chills and fever, internal heat, afternoon fever, hypochondriac pain, and vomiting due to anger, with no fetal growth by the eighth month. This was caused by Liver and Spleen Qi stagnation due to anger; she was treated with Liujunzi Tang (Six-Gentlemen Decoction) added with Chaihu (Bupleurum Root), Zhizi (Gardenia Fruit), Zhike (Aurantium Fructus), Zisu (Perilla Leaf), and Jiegeng (Platycodon Root). Upon recovery from illness, the fetus also grew.
Ante-Natal Bai Zhu Powder: Treats cases where a pregnant woman has pre-existing cold pathogens, resulting in fetal atrophy and failure to grow, or where improper care damages the fetal Qi causing multiple miscarriages.

Cut the herbs into small pieces. Take 3 qian per dose, add one cup of water, three slices of Shengjiang (Fresh Ginger), and one Dazao (Jujube). Decoct until reduced to 70%, strain, and take warm.

Carp (one chi long, cleaned of intestines and scales).
Soak in water until submerged, cook with salt and jujubes until done. Take the broth and drink it slowly. Sweat will appear on the abdomen corresponding to the fetus's location, resembling sweat on an ox's nose. Even if there are signs of threatened abortion or fetal instability, performing this method every ten days or so will promote fetal growth and ensure safety.
