【紫河车】
性味归经，各类书籍均未记载。主治男子身体消瘦虚弱，因内伤几乎致死的情况，能解除药箭之毒。初潮的经血（首经）仍属纯阳之性，能够起死回生。
按语：月经血的补益作用，确实有起死回生的功效，但如今很少有人能使用它，真是可惜啊！
【发】
味道苦，性质微温，无毒，入心经。主治咳嗽、五种淋证（五淋），大小便不通。烧成灰后吹入鼻腔，可立即止住鼻出血（衄血）。也主治小儿惊风癫痫。胎发以及儿童男女剃下的头发效果更佳。多产妇人的头发，烧成灰后用酒送服，极善于催生。
按语：头发是血液的剩余部分。而心脏主司血液。所以头发独入心经。朱丹溪称其补阴非常快捷，这确实是有所依据的。
雷公说：凡是要使用的头发，必须选用二十岁以上、无疾病、面色红白健康的男子头顶剪下的头发为佳。凡是用于丸剂、散剂或膏剂中，需先……（原文此处中断）
【紫河车】
味道甘甜，性质大温，无毒，入心、脾、肾三经。主治各种虚损、百种损伤、五种劳损和七种内伤、骨蒸潮热、身体虚弱气短、吐血鼻衄、男子精液衰少、妇人不孕，确实是仙丹般的药物。选取肥壮者洗净，抽去紫色的筋络切碎，放入两碗童便中，装入铅瓶，在沸水中隔水炖烂，经过一昼夜才能打开，捣碎成膏状使用。世俗中有埋藏地下日久化作清泉的，名叫“河车水”，主治时行疫病引起的热狂、小儿丹疹热毒。
按语：紫河车味道甘甜，适宜归于脾经；它是父亲的精液，适宜归于肾脏；它是母亲的血液，适宜进入心家。由于它是精血结合而成，在没有形成男女之前，先确立了胚胎，浑然如太虚之境，实际上是乾坤的橐龠（风箱），铅汞（炼丹术语，喻阴阳）的根基。九九之数足满，胎儿便承载其中而得名“河车”。又名为“紫”，是因为红色与黑色相杂。契合坎离之色，得到妙合之精华，虽然形成了后天的形体，实则禀受了先天的元气，其补益之功，更没有什么能与之相比。只是它的性质温热，如果有火证的患者，必须经过炮制处理，才不会产生其他祸患。
[Placenta Hominis (Zi He Che)]
The nature, flavor, and meridian tropism are not recorded in various texts. It primarily treats emaciation in men, near-fatal internal injuries, and resolves the toxicity of medicated arrows. The first menstruation (Shou Jing) still belongs to pure Yang nature and can restore life.
Commentary: The tonifying effect of menstrual blood indeed possesses the power to revive the dead, yet nowadays few people know how to use it. What a pity!
[Hair]
Bitter in flavor, slightly warm in nature, non-toxic, enters the Heart Meridian. It primarily treats cough, five types of strangury (Wu Lin), and obstruction of both urination and defecation. When burned to ash and blown into the nasal cavity, it immediately stops epistaxis (Nu Xue). It also primarily treats pediatric convulsions and epilepsy. Fetal hair, as well as hair shaved from children (male or female), is particularly effective. Hair from women who have given birth many times, when burned to ash and taken with wine, is extremely effective for facilitating childbirth.
Commentary: Hair is the surplus of blood. Since the Heart governs blood, hair exclusively enters the Heart Meridian. Zhu Danxi claimed that its ability to tonify Yin is very rapid, which is indeed well-founded.
Lei Gong stated: For usage, one must select hair cut from the crown of the head of a man aged twenty or above, who is free from disease and has a ruddy complexion. When used in pills, powders, or ointments, it must be processed first... [Text cuts off here]
[Placenta Hominis (Zi He Che)]
Sweet in flavor, strongly warm in nature, non-toxic, enters the Heart, Spleen, and Kidney meridians. It primarily treats various deficiencies and hundred damages, five labors and seven injuries, bone-steaming tidal fever, physical weakness and shortness of breath, hematemesis and epistaxis, seminal depletion in men, and infertility in women. It is truly an elixir of immortality. Select plump specimens, wash them clean, remove the purple veins, and chop them into pieces. Place them in two bowls of infant urine (Tong Bian), put them in a lead bottle, and simmer over boiling water until soft. Only open after a full day and night, then pound into a paste for use. In secular practice, those buried underground for a long time that transform into clear spring water are named "He Che Shui" (River Cart Water), primarily treating heat-induced mania from epidemic fevers and heat toxins in pediatric erysipelas (Dan Zhen).
Commentary: Zi He Che is sweet in flavor, thus suitable for entering the Spleen; it is the essence of the father, thus suitable for entering the Kidney; it is the blood of the mother, thus suitable for entering the Heart. As it is formed by the union of essence and blood, before the formation of male or female characteristics, the embryo is established first, resembling the Great Void. It is essentially the bellows of Heaven and Earth, and the foundation of Lead and Mercury (alchemical terms for Yin and Yang). When the cycle of ninety-nine is complete, the fetus rides upon it, hence the name "He Che" (River Cart). It is also called "Zi" (Purple) because red and black colors mix. It harmonizes the colors of Kan and Li, obtaining the essence of subtle union. Although it forms a postnatal shape, it actually inherits prenatal Qi. Its tonifying merit is unmatched. However, since its nature is warm, patients with Fire syndromes must undergo processing to avoid adverse effects.
