大便不通名锁肚，皆缘热毒受胎中，朱蜜捻金俱可用，急咂五心脐下通。
【注】小儿初生之日或次日即大便者，俗
云下脐屎。此肠胃通和，幽门润泽也。若至二三日不大便者，名曰锁肚，乃胎中受辛热
之毒，气滞不通也。其儿必面赤、腹胀、不乳、多啼，宜先用朱蜜法治之，设若不应，用
一捻金量儿与之。继令妇人以温水漱口，咂儿前后心、手足心并脐下，共七处，以皮见
红赤色为度，须臾大便自通矣。
朱蜜法（方见拭口）
一捻金（方见不乳）
二便俱秘胎热极，木通散与紫霜丸行热开结真神妙，口嘬之法悉如前。
【注】小儿初生大小便不通者，最为急候，乃胎中热毒太甚而成也。急用前口咂五心脐
下法，再以木通散行其热，紫霜丸开其结，庶可望生。若延至七日，谓之一腊，肚腹硬胀，
常作呻吟，则难治矣！

【方歌】二便闭兮如何医，木通散用甚为奇，车蓄瞿通苓栀子，滑芩甘草大黄宜。
紫霜丸
代赭石（火煨醋浸三、五次，研，一两） 赤石脂（一两） 杏仁（炒，去皮尖，六十粒） 巴豆（去

大便不通称为“锁肚”，都是因为胎儿在母体内受热毒影响所致。朱砂蜜法和一捻金方剂都可以使用，紧急时可用口吸吮法刺激五心（两手心、两足心及膻中穴）和脐下部位以通利大便。
【注】小儿出生当天或第二天排大便的，俗称“下脐屎”。这是肠胃通畅调和、幽门润泽的表现。如果到了二三天还不排大便，就叫做“锁肚”，这是因为胎中受辛热之毒，导致气机阻滞不通。患儿必然出现面红、腹胀、不吃奶、多啼哭等症状。适宜先用朱蜜法治疗，如果无效，则给患儿服用适量的一捻金。随后让妇女用温水漱口，吸吮患儿的前后心、手足心以及脐下，共七处，以皮肤呈现红赤色为度，不久大便自然通畅。
大小便都闭塞是胎热极盛所致，木通散与紫霜丸可行热开结，效果神奇巧妙，口吸之法完全如前所述。
【注】小儿出生后天小便都不通的，是最危急的情况，这是由于胎中热毒太甚而形成的。紧急时使用前面的口吸五心和脐下法，再用木通散行其热，紫霜丸开其结，这样才有望存活。如果拖延到七天，称为“一腊”，此时肚腹硬胀，经常发出呻吟声，那就难以治疗了！
木通散

引用灯心草水煎服，或者加入薄荷同煎。
【方歌】二便闭兮如何医，木通散用甚为奇，车蓄瞿通苓栀子，滑芩甘草大黄宜。
紫霜丸
代赭石（火煨醋浸三至五次，研细，一两） 赤石脂（一两） 杏仁（炒，去皮尖，六十粒） 巴豆（去油膜，三十粒）
以上研成细末，用饭糊制成如麻子大小的丸剂，每日服用三丸，白开水送服。
Impassable defecation is named "Suo Du" (Lock Belly), all caused by heat-toxin received in the womb. Zhu Mi (Cinnabar Honey) and Yi Nian Jin (One Pinch Gold) are both applicable; urgently, apply the mouth-sucking method to the Five Centers (Wu Xin) and below the umbilicus to unblock.
[Note] When an infant passes stool on the day of birth or the next day, it is colloquially called "Xia Qi Shi" (Passing Umbilical Stool). This indicates that the intestines and stomach are smooth and harmonious, and the pylorus is moist. If there is no stool for two or three days, it is named "Suo Du" (Lock Belly), resulting from heat-toxin of acrid and hot nature received in the fetus, causing qi stagnation and blockage. The child must present with a red face, abdominal distension, refusal to nurse, and frequent crying. It is appropriate to first use the Zhu Mi method; if ineffective, administer an age-appropriate dose of Yi Nian Jin. Subsequently, have a woman rinse her mouth with warm water and suck the child's anterior and posterior heart areas, palms, soles, and below the umbilicus, totaling seven points, until the skin turns reddish. Shortly thereafter, the stool will pass naturally.
Zhu Mi Method (Formula see Chapter: Cleaning Mouth)
Yi Nian Jin (Formula see Chapter: Refusal to Nurse)
When both urine and stool are blocked, it indicates extreme fetal heat. Mu Tong San (Akebia Decoction) and Zi Shuang Wan (Purple Frost Pill) can move heat and resolve accumulation, truly miraculous; the mouth-sucking method is exactly as described before.
[Note] When an infant cannot pass both urine and stool at birth, it is the most critical condition, formed by excessive heat-toxin in the fetus. Urgently apply the aforementioned mouth-sucking method to the Five Centers and below the umbilicus, then use Mu Tong San to clear heat and Zi Shuang Wan to resolve accumulation, so there is hope for survival. If delayed to seven days, termed "Yi La" (One Lunar Month/Week), with a hard and distended abdomen and constant moaning, it becomes difficult to treat!
Mu Tong San
Plantaginis Semen (Cheqianzi), Polygoni Cuspidati Caulis (Bianxu), Dianthi Herba (Qumai), Akebiae Caulis (Mutong), Poria Cocos with Red Bark (Chiling), Gardeniae Fructus (Shanzhi), Talcum (Huashi, flown), Scutellariae Radix (Huangqin), Glycyrrhizae Radix et Rhizoma Recens (Sheng Gancao), Rhei Radix et Rhizoma (Dahuang).
Decoct with Junci Medulla (Dengxin) water, or decoct together with Menthae Haplocalycis Herba (Bohe).
[Formula Song] How to treat blocked urine and stool? Mu Tong San is very strange. Cheqian, Bianxu, Qumai, Mutong, Lingzhi, Zhizi, Huashi, Huangqin, Gancao, Dahuang are suitable.
Zi Shuang Wan
Haematitum (Daizheshi, calcined, soaked in vinegar 3-5 times, ground, 1 liang), Halloysit Rubra (Chishizhi, 1 liang), Armeniacae Semen Amarum (Xingren, stir-fried, peel and tip removed, 60 grains), Crotonis Fructus (Badou, oil membrane removed, 30 grains).
Grind all into fine powder, mix with rice paste to make pills the size of hemp seeds. Take three pills daily, washed down with plain water.
