（《拾遗》）
【修治】藏器曰∶此乃衣埋地下，七八年化为水，澄彻如冰。南方人以甘草、升麻和诸
药，瓶盛埋之，三五年后掘出，取为药也。
【气味】辛，凉，无毒。
【主治】小儿丹毒，诸热毒，发寒热不歇，狂言妄语，头上无辜发竖，虚痞等证，天行
热病，饮之立效（藏器）。反胃久病，饮一钟当有虫出
（《拾遗》）
【释名】命蒂。时珍曰∶胎在母腹，脐连于胞，胎息随母。胎出母腹，脐带既剪，一点
真元，属之命门丹田。脐干自落，如瓜脱蒂。故脐者，人之命蒂也。以其当心肾之中，前直
神阙，后直命门，故谓之脐。脐之为言齐也。
【主治】烧末饮服，止疟（藏器）。解胎毒，敷脐疮
【附方】新三。脐汁不干∶绵裹落下脐带，烧研一钱，入当归头末一钱，麝香一字，掺
之。（《全幼心鉴》）预解胎毒∶初生小儿十三日，以本身剪切脐带烧灰，以乳汁调服，可免
痘患。或入朱砂少许。（《保幼大全》）痘风赤眼∶初生小儿脐带血，乘热点之，妙。（《海
上方》）
（《纲目》）
【释名】阴茎。时珍曰∶人阴茎，非药物也。陶九成《辍耕录》载∶杭州沈生犯奸事露，
引刀自割其势，流血经月不合。或令寻所割势，捣粉酒服，不数日而愈。观此则下蚕室者，
不可不知此法也。故附于此云。
【主治】下蚕室，创口不合（时珍）。
【修治】陈藏器说：这是将胎盘埋在地下，经过七八年化成水，清澈透明像冰一样。南方人用甘草、升麻和其他药物混合，装在瓶子里埋入地下，三五年后挖出来，取用作药材。
【气味】味辛，性凉，无毒。
【主治】小儿丹毒，各种热毒证，寒热往来不止，胡言乱语，头上无根头发竖起，虚胀痞满等证候，时行热病，服用后立即见效（陈藏器）。反胃久病，饮服一钟会有虫体排出。
【释名】命蒂。李时珍说：胎儿在母腹中，脐带连接于胎盘，胎儿的呼吸随母亲而调节。胎儿产出母腹后，脐带被剪断，一点真元之气归属于命门丹田。脐带干枯自然脱落，就像瓜果脱离瓜蒂。所以脐带，是人的生命之蒂。因为它位于心与肾之间，前面正对神阙穴，后面正对命门穴，所以称为脐。脐字的含义是整齐、中心。
【主治】烧成粉末后用水冲服，可止疟疾（陈藏器）。解除胎毒，外敷治疗脐疮。
【附方】新收录三方。脐汁不干：用绵包裹脱落的脐带，烧成炭研末一钱，加入当归头末一钱，麝香一字量，撒敷伤口。（《全幼心鉴》）预先解除胎毒：初生婴儿十三天，将其自身剪下的脐带烧成灰，用乳汁调服，可以避免患痘疹。或者加入少许朱砂。（《保幼大全》）痘风赤眼：初生婴儿脐带血，趁热点涂患处，效果奇妙。（《海上方》）
【释名】阴茎。李时珍说：人的阴茎，不是药物。陶宗仪《辍耕录》记载：杭州沈生因奸情败露，用刀割下自己的生殖器，流血一个月伤口不愈合。有人让他寻找被割下的生殖器，捣碎成粉用酒送服，几天后就痊愈了。由此看来，接受宫刑的人，不能不知道这种方法。所以附记在这里。
【主治】接受宫刑后，创口不愈合（李时珍）。
[Preparation] Chen Zangqi stated: This is obtained by burying the placenta underground for seven or eight years until it liquefies, becoming clear and transparent like ice. People in the southern regions mix licorice root (Gancao), cimicifuga rhizome (Shengma), and other herbs, seal them in a bottle, and bury it underground. After three to five years, they dig it up and use it as medicine.
[Flavor and Nature] Pungent, cool, non-toxic.
[Indications] Erysipelas in children, various heat-toxin syndromes, persistent alternating chills and fever, delirious speech, erection of hair on the head without roots, deficiency-type distension and fullness, and epidemic febrile diseases. Drinking this yields immediate results (Chen Zangqi). For chronic regurgitation (Fanwei), drinking one cup may result in the expulsion of parasites.
[Names] Mingdi (Life Umbilical Cord). Li Shizhen stated: While the fetus is in the mother's womb, the umbilical cord connects to the placenta, and fetal respiration follows the mother's rhythm. After birth, once the umbilical cord is cut, a trace of true Yuan Qi belongs to the Mingmen Dantian. The dried umbilical cord falls off naturally, much like a melon detaching from its stem. Therefore, the umbilical cord is the "life stem" of humans. Because it lies between the heart and the kidneys, directly anterior to the Shenque acupoint and posterior to the Mingmen acupoint, it is called the umbilicus (Qi). The character "Qi" implies alignment or center.
[Indications] Ingested as a powder after calcination to stop malaria (Chen Zangqi). Resolves fetal toxins; applied externally to treat omphalitis (umbilical sores).
[Attached Prescriptions] Three new prescriptions.
1. For umbilical discharge that does not dry up: Wrap the fallen umbilical cord in cotton, burn it to ash, grind into powder (one qian), mix with powder of Angelica sinensis root head (one qian) and musk (one zi), and apply topically. (Quanyou Xinjian)
2. To preemptively resolve fetal toxins: On the thirteenth day after birth, take the infant's own severed umbilical cord, burn it to ash, and administer mixed with breast milk. This can prevent smallpox. A small amount of cinnabar (Zhusha) may be added. (Baoyou Daquan)
3. For measles-induced wind and red eyes: Take the blood from the newborn's umbilical cord while warm and apply it to the affected area. This is highly effective. (Haishang Fang)
[Names] Penis. Li Shizhen stated: The human penis is not used as medicine. Tao Zongyi's *Zhuogeng Lu* records: A man named Shen from Hangzhou, whose adultery was exposed, cut off his own genitals with a knife. The wound bled for a month without healing. Someone advised him to find the severed part, crush it into powder, and ingest it with wine. He recovered within a few days. From this, we see that those undergoing castration (entering the silkworm chamber) must know this method. Hence, it is recorded here.
[Indications] For wounds following castration that fail to heal (Li Shizhen).
