脐带烧灰存性，主疗虚寒疟疾，更解胎毒稀痘，调元免惊。
这是气血所化生的液体。味道甘甜，气性平和，没有毒性，归入心、肾、脾经，是滋润肺脏、有益寿命、延年益寿的圣药。
将人乳晒干后，加入四君子汤（由人参、白术、茯苓、甘草组成的补气基础方）中，能大补气血，调和畅达营卫之气，培补元阳，滋润生长肌肉，保持容颜年轻、视力明亮，安定滋养神魂，五脏都能得到补益，肠胃得以滋润，可治疗消渴病（糖尿病类症状），退除虚热，缓解噎膈（吞咽困难），补益虚劳，祛除眼睛红肿，停止流泪，长期服用使人气息冲和，身体肥壮白皙、光泽润泽。又用于治疗中风导致的瘫痪，手足疼痛，不能行动行走，驱除一切虚损劳症，这是以人体之血来补益人体的方法。但是其功效专门在于补阴，如果是阳气虚弱、胃气衰弱、脾寒导致腹泻的人禁止服用。
主治（参考《痘疹合参》）：治疗眼睛发热、红肿疼痛，补益五脏的精血，停止流泪、明亮视力，痘疮不出浆者，用此来辅助它，但已经断奶很久的人，初次服用容易大便溏薄。
按语：乳汁由血液转化而来，主要归属于脾胃，受冲脉和任脉的统摄，未怀孕时向下成为月经，一旦怀孕则留存下来滋养胎儿。产后则由赤色变为白色，由下降转为上升，这是造化玄妙细微的奥妙，是祛病延年的药物。世俗人多认为乳汁能滑利肠道，如果真是这样，那么天下就没有拉肚子的婴儿了。等到与食物混合进食，反而可能引发腹泻，所以在半夜时分进服较好。前后都建议在远离饮食的时候服用最好。服用孔歌说：仙家的酒，仙家的酒，两个葫芦盛一斗，五行酿造出的真醍醐，不离人间处处都有。丹田若是干涸的时候，咽下重楼（食管/气管部位）滋润枯朽。清晨如果能饮一升多，就能返老还童，像天地一样长久。曝晒制作成粉末，名为乳金丹尤其好，只有脾胃泄泻的人不适合使用。
脐带，是生命的蒂结。位于心与肾之间，是真元之气归宿的地方，在母腹中治疗期间，脐带连接胞宫，喘息呼吸滋养的奥妙，从此通畅，胎儿离开母腹，脐带剪断，则一点真元之气，从此回归入命门丹田。所以脐带被称为命蒂。脐带也是真气汇聚的地方，用它来治疗疟疾，是因为久疟导致极度虚寒，借助其气来补益不足。当今世人用小儿脱落的脐带，烧灰存性后服用，可以解除胎毒、使痘疹稀疏，以及培补元气，避免惊风，这也是返本还元的意义。脐带烧灰存性，主治虚寒疟疾，更能解除胎毒、使痘疹稀疏，调理元气、避免惊风。
It is the fluid transformed from Qi and Blood. Its taste is sweet, its nature is neutral, it is non-toxic, enters the Heart, Kidney, and Spleen meridians, and is a sacred medicine for moistening the Lungs, benefiting longevity, and extending life.
When human milk is dried and added to Sijunzi Tang (Four Gentlemen Decoction), it greatly tonifies Qi and Blood, harmonizes and unblocks Ying (Nutritive) and Wei (Defensive) Qi, cultivates Yuan Yang (Original Yang), moistens and promotes muscle growth, preserves youthful appearance and brightens vision, calms and nourishes the Shen (Spirit), tonifies all five Zang organs, moistens the intestines and stomach, treats Xiao Ke (Wasting-Thirst syndrome), clears deficient heat, relieves Ye Ge (dysphagia/choking sensation), supplements deficiency exhaustion, dispels eye redness, stops tearing, and long-term consumption makes one's Qi harmonious and vigorous, resulting in a plump, fair, and lustrous complexion. It also treats stroke-induced paralysis, pain in the hands and feet, inability to move or walk, and drives away all deficiency-exhaustion syndromes; this is a method of using human essence to supplement the human body. However, its efficacy specializes in tonifying Yin; therefore, it is contraindicated for those with Yang deficiency, weak Stomach Qi, or Spleen Cold causing diarrhea.
Main indications (referencing *Douzhen Hecan*): Treats eye heat, redness, and pain; tonifies the Essence and Blood of the five Zang organs; stops tearing and brightens vision; for pustular eruptions that fail to fill with pus, use this to assist them. Note: For those who have been weaned for a long time, initial consumption may easily lead to loose stools.
Commentary: Milk is transformed from blood, primarily governed by the Spleen and Stomach, and regulated by the Chong and Ren vessels. Before pregnancy, it flows downward as menstrual blood; once pregnant, it remains to nourish the fetus. After childbirth, it changes from red to white, shifting from descending to ascending. This is the profound subtlety of creation, a medicine for dispelling illness and extending life. The common people often believe that milk can lubricate the intestines; if this were true, there would be no infants suffering from diarrhea in the world. When mixed with food, it may induce diarrhea, so it is best administered at midnight. It is advisable to take it well away from meals. As sung in Kong's verse: "The Immortal's wine, the Immortal's wine, two gourd flasks hold one dou, brewed from the Five Elements into true醍醐 (Ghee/Essence), present everywhere in the human realm. When the Dantian (Elixir Field) is dry and barren, swallow down the Chonglou (Esophagus/Throat) to moisten the withered and decayed. If one can drink over a sheng in the early morning, one returns to youth and old age, lasting as long as heaven and earth." Sun-dried and made into powder, named Rujin Dan (Milk Golden Pill), is especially good, but not suitable for those with Spleen-Stomach diarrhea.
The umbilicus is the root of life. Located between the Heart and Kidney, it is the residence of True Yuan Qi. During gestation in the womb, the umbilical cord connects to the uterus; the wonder of breathing and nourishment flows through here. After birth, when the umbilical cord is cut, a point of True Yuan Qi returns to the Mingmen (Gate of Life) and Dantian. Thus, the umbilical cord is called the "Life Root." The umbilical cord is also a gathering place for True Qi. Using it to treat malaria addresses cases of chronic malaria with severe deficiency-cold, borrowing its Qi to supplement insufficiency. In modern times, the umbilical cords shed by infants are burned to ash while retaining their nature and taken orally to resolve fetal toxins, attenuate smallpox/rashes, cultivate Original Qi, and prevent convulsions; this embodies the principle of returning to the origin and restoring originality. Umbilical cord ash, prepared by burning to retain nature, treats deficiency-cold malaria, resolves fetal toxins, attenuates rashes, regulates Original Qi, and prevents convulsions.
