子淋谓妊娠小便涩少也，乃肾与膀胱虚热不能治水。然妊妇胞系于肾，肾间虚热而成斯症。甚者心烦闷乱。用下方∶
子淋散
治妊娠小便涩痛频数。
麦门冬（去心） 赤茯苓 木通 大腹皮（洗去沙土，姜汁拌炒） 甘草 淡竹叶
上 ，水煎服。
车前散
治小便淋沥或不通，下焦有热者。
车前子 当归 陈皮 赤芍药 槟榔 赤茯苓 滑石 木通 石苇（去毛炙）
上 ，水煎服。
转胞谓妊娠卒不得小便也。因胎长逼近于胞，胞为所逼，令人数溲。胞即膀胱也。然子淋与转胞相类，但小便频数
点滴而痛为子淋，频数出少不痛为转胞，间有微痛，终是与淋不同，并宜五苓散加阿胶。
冬葵子散
治孕妇转胞小便不通。
冬葵子 滑石 栀子（炒） 木通（各五钱）
上 一剂，水一钟半，煎至一钟，空心温服。此药滑胎，临月可用。若六、七个月以前不可用。
又方∶冬葵子、滑石、栀子，为末，田螺肉捣膏或生葱汁调膏，贴脐中立通。
妊娠经水时下，此由冲任气虚，不能约制。盖心小肠二经相为表里，上为乳汁，下为月水。故妊娠经水壅之以养胎，
蓄之以为乳。若经水时下，名曰胎漏，血尽则毙矣。属气血虚有热。用下方∶
胶艾四物汤
当归 黄芩（酒炒） 白芍（酒炒） 白术（土炒） 熟地黄（姜汁炒） 艾叶（少许） 砂仁（炒） 香附（童
便炒黑） 真阿胶（蛤粉炒珠）
上 一剂，用粳米同煎服。
芎归汤（刘敏庵传）
治胎漏下血不止，或心腹胀满，一服立效。
当归尾 南川芎（各五钱）
上 一剂，黄酒煎，临卧服，入童便一盏，即止。
子淋是指妊娠期间小便涩滞、尿量减少的症状，这是由于肾与膀胱的虚热导致无法正常运化水液。然而孕妇的胞宫系连于肾，肾间的虚热引发了此症。病情严重者会出现心烦意乱、胸闷不安的表现。使用以下方剂：
子淋散
治疗妊娠期间小便涩痛且频数。
麦门冬（去除心部） 赤茯苓 木通 大腹皮（清洗去除沙土，用姜汁拌炒） 甘草 淡竹叶
以上药材，加水煎煮后服用。
车前散
治疗小便淋漓不尽或不通畅，且下焦有热的情况。
车前子 当归 陈皮 赤芍药 槟榔 赤茯苓 滑石 木通 石苇（去除毛刺并炙烤）
以上药材，加水煎煮后服用。
转胞是指妊娠期间突然无法排尿的症状。这是因为胎儿长大逼近胞宫，压迫胞宫，导致患者频繁想排尿但排不出。这里的“胞”即指膀胱。然而子淋与转胞症状相似，区别在于：小便频数、点滴而出且疼痛的是子淋；小便频数但量少且不痛的是转胞；偶尔有轻微疼痛的，终究与淋证不同，这两种情况都适宜使用五苓散加阿胶。
冬葵子散
治疗孕妇转胞导致的小便不通。
冬葵子 滑石 栀子（炒制） 木通（各五钱）
以上药材为一剂，用水一钟半，煎至一钟，空腹时温服。此药具有滑胎作用，临近预产期可以使用。若在怀孕六、七个月之前则不可使用。
另一个方子：将冬葵子、滑石、栀子研成粉末，用田螺肉捣成的膏或生葱汁调和成药膏，贴在肚脐上，很快即可通畅。
妊娠期间经血时下，这是由冲脉和任脉气虚，不能固摄制约所致。因为心和小肠两经互为表里，在上化为乳汁，在下化为月经。所以妊娠期经血应壅聚以滋养胎儿，蓄积以备日后化为乳汁。如果经血不时下泄，称为胎漏，若血液流尽则会导致死亡。这属于气血虚弱且有内热的证候。使用以下方剂：
胶艾四物汤
当归 黄芩（酒炒） 白芍（酒炒） 白术（土炒） 熟地黄（姜汁炒） 艾叶（少许） 砂仁（炒） 香附（童便炒黑） 真阿胶（蛤粉炒成珠状）
以上药材为一剂，用粳米同煎后服用。
芎归汤（由刘敏庵传授）
治疗胎漏下血不止，或伴有心腹胀满，服用一剂后立即见效。
当归尾 南川芎（各五钱）
以上药材为一剂，用黄酒煎煮，睡前服用，加入一盏童便，出血即可停止。
Zilin (Stranguria during Pregnancy) refers to the symptom of scanty and difficult urination during pregnancy, caused by deficient-heat in the Kidney and Bladder failing to manage water metabolism. However, since the Bao (uterus) is connected to the Kidney in pregnant women, deficient-heat within the Kidney gives rise to this syndrome. In severe cases, it manifests as mental restlessness and oppression. Use the following prescription:
Zilin San (Subling Dispersion)
Treats stranguria with pain and frequency during pregnancy.
Ophiopogonis Radix (Ouyidong, 麦门冬) [removed heart], Poria Cocos (Chifuling, 赤茯苓), Akebiae Caulis (Mutong, 木通), Arecae Pericarpium (Dafupi, 大腹皮) [washed to remove sand, stir-fried with ginger juice], Glycyrrhizae Radix et Rhizoma (Gancao, 甘草), Lophatheri Herba (Danzhuye, 淡竹叶).
The above ingredients are decocted in water and taken orally.
Cheqian San (Plantago Seed Dispersion)
Treats dribbling or obstruction of urine with heat in the Lower Jiao.
Plantaginis Semen (Cheqianzi, 车前子), Angelicae Sinensis Radix (Danggui, 当归), Citri Reticulatae Pericarpium (Chenpi, 陈皮), Paeoniae Radix Rubra (Chishaoyao, 赤芍药), Areca Semen (Binglang, 槟榔), Poria Cocos (Chifuling, 赤茯苓), Talcum (Huashi, 滑石), Akebiae Caulis (Mutong, 木通), Pyrosiae Frond (Shiwei, 石苇) [de-haired and roasted].
The above ingredients are decocted in water and taken orally.
Zhuanbao (Displacement of the Uterus/Bladder) refers to the sudden inability to urinate during pregnancy. This occurs because the growing fetus presses against the Bao (uterus/bladder), causing frequent urges to void without relief. Here, "Bao" refers to the Bladder. Although Zilin and Zhuanbao are similar, they differ as follows: frequent, scanty, and painful urination characterizes Zilin; frequent, scanty, but painless urination characterizes Zhuanbao; even if there is slight pain, it remains distinct from stranguria. Both conditions are suitable for treatment with Wuling San (Five-Ingredient Powder with Poria) plus Ejiao (Donkey-hide Gelatin).
Dongkui Zi San (Malva Seed Dispersion)
Treats urinary obstruction due to Zhuanbao in pregnant women.
Malvae Semen (Dongkuizi, 冬葵子), Talcum (Huashi, 滑石), Gardeniae Fructus (Zhizi, 栀子) [roasted], Akebiae Caulis (Mutong, 木通) [each 5 qian].
One dose is decocted in 1.5 zhong of water until reduced to 1 zhong, and taken warm on an empty stomach. This medicine has a slippery effect that may induce abortion; it can be used near term. It must not be used before the sixth or seventh month.
Another method: Powder Dongkui Zi, Huashi, and Zhizi. Mix with paste made from fresh apple snail meat or raw green onion juice, and apply to the umbilicus. Urination will clear quickly.
Vaginal bleeding during pregnancy is caused by deficiency of Qi in the Chong and Ren vessels, failing to restrain blood. Since the Heart and Small Intestine meridians are exterior-interior partners, fluids transform into milk upwards and menstruation downwards. Therefore, during pregnancy, menstrual blood should be retained to nourish the fetus and stored to become milk later. If vaginal bleeding occurs intermittently, it is called Tailou (Fetal Leakage); if the blood is exhausted, death ensues. This pattern belongs to Qi and Blood deficiency with internal heat. Use the following prescription:
Jiao'ai Siwu Tang (Ejiao and Four Substances Decoction)
Angelicae Sinensis Radix (Danggui, 当归), Scutellariae Radix (Huangqin, 黄芩) [stir-fried with wine], Paeoniae Radix Alba (Baishao, 白芍) [stir-fried with wine], Atractylodis Macrocephalae Rhizoma (Baizhu, 白术) [stir-fried with soil), Rehmanniae Radix Preparata (Shudihuang, 熟地黄) [stir-fried with ginger juice], Artemisiae Argyi Folium (Aiye, 艾叶) [a small amount], Amomi Fructus (Sharen, 砂仁) [roasted], Cyperi Rhizoma (Xiangfu, 香附) [stir-fried black with child's urine], True Ejiao (Donkey-hide Gelatin) [fried with clam powder into pearls].
One dose is decocted together with Oryza Sativa Germ (Jingmi, 粳米) and taken orally.
Xiong Gui Tang (Chuanxiong and Angelica Decoction) [Transmitted by Liu Min'an]
Treats persistent bleeding from Tailou, or abdominal distension and fullness; one dose brings immediate relief.
Angelicae Sinensis Radix Caudex (Dangguiwei, 当归尾), Ligusticum Chuanxiong Rhizoma (Nanchuanxiong, 南川芎) [each 5 qian].
One dose is decocted with yellow wine, taken before sleep, with one zhan of child's urine added; bleeding stops immediately.
