Mainly tonifies the five Zang organs (Five Viscera), making the body plump, skin white, and lustrous.
Zhang Cang of the Han Dynasty constantly consumed human milk, thus living to over one hundred years old, with a plump and white appearance like a gourd.

[Verification] *Bie Lu* (Record of Distinction) states: The milk from a male infant born first can treat redness and pain in the eyes with excessive tearing;
it resolves toxicity from eating beef liver cooked alone. If taken mixed with strong decoction of fermented soybeans (Douchi), it is miraculously effective. Additionally, mixing it with sparrow droppings can eliminate eye redness and pterygium (fleshy growth over the cornea).

Taste: bitter. Nature: warm or slightly cold. Non-toxic. Mainly treats five types of strangury (difficult, painful urination) and Guan-Ge syndrome (obstruction preventing urination and causing vomiting), facilitating water passages. It treats epilepsy in children and [stroke/seizures] in adults. Through calcination (burning to ash while preserving properties), it undergoes transformation. When decocted with egg yolk until dissolved into liquid,
it treats pediatric convulsive fever and dysentery.

Li Dang identifies this as hair from an intact boy. The matter of "divine transformation" is not found in other prescriptions. Currently, among common people, elderly women prepare egg preparations for children by boiling hair mixed in for a long time to obtain juice,
and when using hair, they all use the messy hair gathered from fathers' combs. It is unknown what specific substance this "certain hair" refers to? Moreover, this character is absent from dictionaries; its pronunciation might be similar to "Suan". People now refer to alopecia areata as "Suan Fa". Calligraphers also refer to messy hair as "[Character]", fearing that "[Character]" is indeed the pronunciation of "[Character]". The rationale regarding intact boys remains unclear.

[Verification] This refers to the root of the hair. Those aged for a long time are used with miraculous effect. Thus, the character "[Character]" following "Fa" (Hair) is erroneous. Since descriptions of messy hair and scalp dandruff already exist, the explanation for "[Character]" is missing. Furthermore, the efficacy of scalp dandruff is inferior to that of hair roots. Similarly, Tao Hongjing used aged combs, boat algae (Chuan Ru), decaying Pholiota nameko (Bai Tian Gong), and rush mats in his works, which fall under this category. Zhen Liyan wrote "[Character]", which is also "[Character]". Checking dictionaries reveals no "[Character]", only "Fa Quan" (curly/beautiful hair). "Quan" describes beautiful hair, pronounced "Qiu Quan", having sound but no physical substance, whereas "[Character]" is authentic.

Nature: slightly warm. Mainly treats cough, five types of strangury, obstruction of both large and small intestines, pediatric epilepsy, stops bleeding, treats epistaxis (nosebleed). Burned into ash and blown into the affected area brings immediate relief.
This is merely ordinary human hair. Daoist practitioners burn messy hair and nails together; mountain dwellers drink it to foster affection. Its therapeutic nature is similar to that of "[Character]".

[Verification] Ash of messy hair treats Zhuan Bao (retention of urine due to bladder displacement), urinary obstruction, bloody and purulent dysentery, dysphagia, epistaxis, Hu Niao Ci (a type of skin lesion or symptom), Shi Zhu (chronic wasting disease), Ding Zhong (carbuncle), Gu Ju (bone abscess), and miscellaneous sores. Ancient prescriptions use it. Tao Hongjing only knew that the character "[Character]" was absent from dictionaries, failing to realize that "[Character]" was a miswriting of "Fa" (Hair).
