[Human Milk]
Its main efficacy is tonifying the five Zang organs, making the body plump, the skin white, and lustrous.
Tao Hongjing stated: Zhang Cang frequently consumed human milk, thus living beyond a hundred years old, with a body as plump and fair as a gourd. The *Xinxiu Bencao* (Newly Revised Materia Medica) annotation notes: *Mingyi Bielu* (Record of Famous Physicians) records that the milk from a newborn male infant treats toxic sores; when combined with strong soybean paste decoction, it yields miraculous effects. Furthermore, mixing human milk with sparrow feces treats red eyes and pterygium (fleshy growth over the cornea). Ministers Yu Xi et al. respectfully note according to the *Shu Ben*: Human milk is sweet in taste, neutral in nature, and non-toxic. Ri Huazi stated: Human milk is cold in nature. It benefits Qi, treats emaciation and frailty, beautifies the skin, and moistens hair.
*Shenghui Fang* (Holy Benefit Formulas): Treats sudden stroke with inability to speak and stiffness of the tongue root. Take five he of aged vinegar sauce (three-year-old is best) and five he of human milk, grind them together, and squeeze out the juice using raw cloth. Administer in small amounts at any time; after a while, speech should return.
*Qianjin Fang* (Thousand Gold Formulas): Treats amenorrhea (absence of menstruation); drink three he of human milk.
*Jingui Fang* (Essential Prescriptions of the Golden Cabinet): Regarding death caused by eating beef from a snake-bitten animal, how can one know? Beef from an animal that has eaten snake venom is identified by its hair lying flat backwards. If one feels like dying after eating it, drinking one sheng of human milk cures it immediately.
*Yanyi* states: Human milk has many effects in treating eye diseases. Why? The Heart generates blood, and the Liver stores blood; when the Liver receives blood, vision is possible. Water entering the meridians allows blood to form. It is also said: flowing upward it becomes milk, flowing downward it becomes menstrual blood; thus, we know milk is blood. Using it to drop into the eyes, how could it be inappropriate? Blood belongs to Yin, hence its nature is cold. People with internal cold should not consume too much dairy products like milk cakes or cheese. Although referring to cow and sheep milk, they do not transcend the creation of Yin and Yang. Western regions further make butter and cheese from camel and horse milk. For elderly people suffering from mouth ulcers unable to eat, drinking hot human milk is beneficial.

[Head Scum]
It mainly treats strangury (dysuria) with obstruction.
Tao Hongjing stated: Head scum floats on needles due to its greasiness. One should now use head scum from individuals who maintain a lustrous appearance, which can be formed into pills. It also treats dysphagia (difficulty swallowing) and post-illness relapse due to overexertion (Lao Fu). Ministers Yu Xi et al. respectfully note according to *Yaoxing Lun* (Discussion on Drug Properties): Head scum treats dysphagia. Decocted with sour bean water into a paste, immediate cure follows. Ri Huazi stated: It is warm in nature. It treats Gu poison (poisoning from ingested parasites/toxins) and mushroom toxicity; administer with rice water or wine until vomiting occurs.
*Waitai Miyao* (Secret Essentials from the Outer Cabinet): For typhoid fever, to prevent Lao Fu (relapse due to overexertion), burn head scum, make pills the size of sophora seeds, and swallow one pill with water.
*Qianjin Fang*: Treats various evil spirits and demonic influences. Swallow a dose the size of a soybean with water; thus, greasy head scarves are non-toxic. For epidemic Lao Fu with thirst, soak head scum to extract juice, warm and drink one sheng. Another prescription: For poisoning from eating liver of dead birds/beasts. Take one qianbi of old head scarf scum, dissolve in hot water, and ingest. Three-year-old head scarf scum treats sudden heart pain; take juice with boiling water, place the scarf in a quiet place, cover with a bowl, and open simultaneously for cure. "Head scarf" refers to the cloth used to tie hair.
*Zhouhou Beiji Fang* (Emergency Prescriptions Kept Up the Sleeve): For severe sores from dog bites, put a little head scum into the wound and apply hot cow dung externally. Ge Zhichuan treated tight lips by applying head scum. Mei Shi Fang: Treated death from eating horse liver (horse liver poisoning). Take one part head scum, mix with cooked water, and ingest.
Minister Qian's Box Formula: Treated centipede bites, mixed the greasy part of head scum with Sophora root powder, diluted with wine, and applied externally. Liu Juanzi treated splinters of bamboo/wood stuck in flesh; applying head scum makes them emerge.
*Shanghan Leiyao* (Classified Essentials of Cold Damage): For Lao Fu after Shanghan (Cold Damage) and epidemic diseases, hold a pill of head scum the size of a jujube pit in the mouth.
*Fuqi Jingyi* (Essentials of Breathing Practice) records: Liu Jun'an burned his own fallen hair and mixed it equally with head scum for ingestion, three pills the size of soybeans each time. Named "Huan Jing" (Returning Essence), it prevents graying of hair.
