〔论〕 乳汁由血所化。故滋血者还以乳。夫妇人之乳。资以冲脉。因冲与胃经通故也。
冲为血海。而胃为血液化生之府。安得不责其本乎。凡男子以气为主。究气之所生。所生者
肾也。女子以血为主。则当究血之所生。所生者心也。血赤火也。女子之乳白。男子之精亦
白。皆从金也。女子气盛。合于心包络血。即就血所生处而化乳。男子气盛。合于冲脉之血。
即就气所生处而化精。（乳与精俱从血化。而血化俱由于气。但分上下者。分于血与气所生
之处也。化不离生。生亦不离化。上之血生为气化。下之精生为血化耳。）但男女之化乳化
精者。皆不离于脾胃。以其为升降鼓煽运化精微之地也。然则乳汁固不徒少阴血主之所化。
实由肺胃气化之所成矣。第血化之乳。化原固在气。一离乳房。则徒存阴质。而气化已散。

味甘、咸。气性平凉，没有固定的定性。（如果产妇性情平和，饮食清淡，那么她的乳汁性质必然平和；如果产妇性情暴躁，饮酒并食用辛辣食物，或者体内有火病，那么她的乳汁性质必然偏热。）能滋养五脏，明亮眼目，安定神魂，滑利关格（指大小便不通的病症），治疗消瘦憔悴，润泽皮肤，以及筋脉拘挛、骨骼痿弱，肠胃秘结涩滞。又能补益心气，填补脑髓，止住消渴（糖尿病类症状），治疗风火证候，尤其适合老年人服用。又治疗痰火上冲导致的虚损证候，以及中风后不能言语、左侧肢体瘫痪右侧肢体弛缓、手足疼痛、行动不便、饮食减少等证候。（出自《摄生众妙》）
地黄、当归属于草木类药物，禀受天地偏颇之气，用来治疗血病，力量固然有余；但用来补血虚，力量还不足以达到理想效果。不如频繁服用人乳，不仅补血，而且那些因血病引起的病因，也能通过调养滋润而自愈。加入四物汤中，共同补益精血；加入四君子汤中，共同增益元阳。月经不通者，每日饮用三合人乳。突然失语者，用半合人乳配半升美酒，混合服用。失音不语者，用人乳二合、竹沥二合，温服。虚损劳瘵（慢性消耗性疾病），使用无病妇人的乳汁三酒杯，将瓷碟晒得极热，把乳汁放在其中，再放入少许麝香末、二分木香末，调匀服用。之后饮浓茶一酒盏。如果出现阳气败坏的情况，次日服用接命丹。方子用人乳三酒盏，像前面那样晒热的碟子盛装乳汁，并加入一副人胞（胎盘）粉末，调匀服用。服用完毕后，面部和膝盖都发红，像喝醉了一样想睡觉，只用白粥少量调养即可。眼睛红肿发热，用半合人乳，取十文古铜钱，在铜器中磨至变色，制成稀稠适中的煎剂，装入瓶中收藏，每天点涂数次。或者用人乳浸泡黄连，蒸热后清洗患处。
〔论述〕 乳汁是由血液化生的，所以滋补血液的药物最终还要依靠乳汁来辅助。妇女的乳汁，依赖于冲脉，因为冲脉与胃经相通的关系。冲脉是血海，而胃是血液化生的府库，怎么能不追究它们的根本呢？大凡男子以气为主，探究气的产生，根源在于肾。女子以血为主，则应当探究血的产生，根源在于心。血是红色的，属火；女子的乳汁是白色的，男子的精液也是白色的，都归属于金（白色属金）。女子气盛，结合于心包络之血，就在血产生的地方化为乳汁。男子气盛，结合于冲脉之血，就在气产生的地方化为精。（乳汁与精液都从血液化生，而血液的化生都由于气的作用，只是分为上下两部分，区别在于血与气产生的部位不同。化生不离生长，生长也不离化生，上部的血生化为气化，下部的精生为血化罢了。）但是男女化生乳汁和精液，都不离开脾胃，因为脾胃是升降、鼓动、煽运、化生精微物质的场所。既然这样，那么乳汁确实不仅仅是少阴血主要化生的，实际上是由肺、胃的气化作用所形成的。只是由血化生的乳汁，其化生的本源确实在气，一旦离开乳房，就只剩下阴质的形体，而气化已经消散。所以用来治疗疾病时，必须审慎判断病情是否适宜。比如血虚有热，燥渴枯涸，这是它的对症之处；即使用来培养身体，也必须审慎体质是否适宜。比如体质瘦弱无痰，脏阳胃强，才能见到益处。否则，一概投用只会带来累赘。至于医书说适宜于虚火及中风证候，虚火往往伴有燥痰，而属于阴虚的风证，也不能摄纳痰液归于元气。即使是这些适宜投用的证候，也应当让乳汁作为佐使药发挥作用即可。
人乳属于阴性冷性。如果是脏寒滑泄，以及胃弱脾虚的人，都不宜服用。（仲淳注）
〔修治〕 凡是服用必须热饮，希望使其流行于经络，可以加醇酒调和。如果晒曝成粉，入药尤其好。晒乳粉的方法：遇到有乳汁，立即放入银锅中煎成膏状，用大瓷盘盛放，在阳光下晾晒。必须以水浸湿盘子底部，否则久晒不干。这是未济卦（水火未济）的奥妙所在。
Tastes sweet and salty. The qi nature is neutral and cool, with no fixed qualitative attribute. (If the mother's temperament is peaceful and her diet is bland, her milk will necessarily be neutral in nature; if she is irritable, drinks alcohol, eats pungent foods, or suffers from internal heat diseases, her milk will necessarily be hot in nature.) It nourishes the five zang organs, brightens the eyes, calms the spirit and soul, unblocks obstruction of the upper and lower orifices (referring to conditions of urinary and fecal retention), treats emaciation and debility, moistens the skin, and addresses tendon spasms and bone flaccidity, as well as intestinal and gastric constipation. It also benefits heart qi, replenishes brain marrow, stops thirst-quenching disorders (symptoms similar to diabetes), and treats wind-heat syndromes; it is particularly suitable for the elderly. It further treats conditions of deficiency damage caused by rising phlegm-fire, aphasia following stroke, left-sided hemiplegia with right-sided flaccidity, pain in the hands and feet, difficulty in movement, and reduced appetite. (From *Shesheng Zhongmiao*)
*Rehmanniae Radix Preparata* (Dihuang) and *Angelicae Sinensis Radix* (Danggui) are herbal substances that acquire the biased qi of heaven and earth. While their strength is sufficient for treating blood diseases, it is still inadequate for tonifying blood deficiency. It is better to frequently consume human milk; not only does it tonify blood, but etiologies arising from blood disorders can also heal themselves through nourishing and regulating care. When added to *Sìwù Tāng* (Four Substances Decoction), it jointly tonifies essence and blood; when added to *Sìjūnzǐ Tāng* (Four Gentlemen Decoction), it jointly benefits primal yang. For amenorrhea, drink three *hé* (approx. 50ml) of human milk daily. For sudden aphasia, mix half a *hé* of human milk with half a *shēng* (approx. 200ml) of fine wine and take together. For loss of voice and inability to speak, take two *hé* each of human milk and bamboo sap (*Zhúlì*), warmed before administration. For deficiency consumption and chronic wasting diseases, use three wine cups of milk from a healthy woman. Heat a porcelain plate extremely hot in the sun, place the milk on it, add a small amount of *Moschus* powder and two *fēn* of *Aucklandiae Radix* (Mùxiāng) powder, mix evenly, and take. Afterwards, drink one wine cup of strong tea. If signs of yang collapse appear, take *Jièmìng Dān* (Life-Receiving Pill) the next day. This formula uses three wine cups of human milk, placed on the sun-heated plate as described above, mixed with one whole placenta powder (*Rénbāo*), and taken. After ingestion, the face and knees turn red, resembling drunkenness and sleepiness; nourish gently with small amounts of white rice porridge. For red, swollen, and hot eyes, use half a *hé* of human milk. Take ten ancient copper coins, grind them in a copper vessel until they change color, mix into a decoction of appropriate viscosity, store in a bottle, and apply several times daily. Alternatively, soak *Coptidis Rhizoma* (Huánglián) in human milk, steam until hot, and wash the affected area.
[Discussion] Milk is transformed from blood; therefore, those who nourish blood ultimately rely on milk. Women's milk relies on the Chong Mai (Penetrating Vessel) because the Chong Mai connects with the Stomach Meridian. The Chong Mai is the Sea of Blood, and the Stomach is the fu organ where blood is generated. How can one not trace back to these roots? Generally, men prioritize Qi; investigating the origin of Qi leads to the Kidney. Women prioritize Blood; investigating the origin of Blood leads to the Heart. Blood is red and belongs to Fire; women's milk is white, and men's essence is also white, both belonging to Metal (White corresponds to Metal). When women's Qi is abundant, it combines with the blood of the Pericardium Luo, transforming into milk at the site where blood is generated. When men's Qi is abundant, it combines with the blood of the Chong Mai, transforming into essence at the site where Qi is generated. (Both milk and essence transform from blood, and blood transformation depends on Qi. The distinction between upper and lower lies in the sites of blood and Qi generation. Transformation does not separate from generation, nor does generation separate from transformation; the upper blood generates via Qi transformation, while the lower essence generates via blood transformation.) However, the transformation of milk and essence in both men and women does not depart from the Spleen and Stomach, as these are the sites of ascending and descending, stirring and promoting, and transforming subtle essences. Thus, milk is indeed not solely transformed by the Shao Yin Blood, but is actually formed by the Qi transformation of the Lung and Stomach. Although the source of blood-transformed milk lies in Qi, once it leaves the breast, only the yin substance remains, and the Qi transformation has dissipated. Therefore, when using it to treat disease, one must carefully assess whether the condition is suitable. For instance, blood deficiency with heat, dryness, thirst, and dehydration are direct indications. Even when used for cultivation, one must assess bodily suitability: for those who are thin without phlegm and possess strong visceral yang and stomach heat, it provides benefit. Otherwise, indiscriminate use brings only burden. Regarding medical texts stating suitability for deficient fire and stroke syndromes: deficient fire often involves dry phlegm, and wind syndromes belonging to yin deficiency cannot retain phlegm returning to the primordial qi. Even for these indicated conditions, milk should serve merely as an assistant or guide herb.
Human milk is yin-natured and cold. It is unsuitable for those with cold viscera and loose stools, or weak stomach and spleen deficiency. (Note by Zhongchun)
[Processing] It must be drunk warm to facilitate circulation through the meridians; adding fine wine aids this. If dried into powder for medicinal use, it is especially effective. Method for drying milk powder: Upon obtaining milk, immediately boil it in a silver pot into a paste, spread it on a large porcelain plate, and dry it in the sun. The bottom of the plate must be immersed in water; otherwise, prolonged sun exposure will not dry it. This represents the subtlety of the *Wèijì* Hexagram (Fire over Water, Not Yet Completed).
