[Names] Earwax (from *Ben Cao Gang Mu*), Brain Paste (from *Ri Hua Zi Ben Cao*), Mud Pill Fat.
Li Shizhen states: According to *Xiu Zhen Zhi Nan* (Guide to Cultivation), Kidney Qi ascends from the right side of the Spleen into the ear, transforming into "Er Sai" (earwax). The ears are the orifices of the Kidneys. When Kidney Qi is unobstructed, there is no blockage; when blocked, Qi flow is impeded, hence it is called "Sai" (blockage).
[Properties and Flavor] Salty, bitter, warm, toxic.
[Indications] Mania, possession by spirits, and alcoholism (from *Da Ming Ben Cao*). For bites/stings from snakes, insects, and centipedes, applying this substance is effective (Li Shizhen).
[Attached Prescriptions] Six new prescriptions.
Snake and insect bites: Mix human earwax with earthworm excrement and apply to the wound. Allow yellow fluid to drain completely for immediate cure. (*Shou Yu Fang*)
Traumatic wind-stroke: Use the membrane from the patient's ear and scrape powder from fingernails. Mix with saliva and apply to the wound for immediate effect. (*Ru Men Shi Qin*)
Ulcers caused by scratching infected with water-dampness, unbearable swelling and pain: Seal the area with earwax. After one night, all fluid drains out and healing occurs. Zheng Shifu said: I often suffered from this condition, and a beggar passed on this prescription. (*Yi Shuo*)
Carbuncles and malignant sores: Take fresh brain (i.e., earwax) and salt mud in equal parts, grind evenly. Mix with dandelion juice to form small cakes and apply as a sealant. Highly effective. (*Sheng Hui Fang*)
All eye diseases: Dry the earwax. Each time, take an amount the size of a millet grain and instill nightly. (*Sheng Hui Fang*)
Infant nocturnal crying, fright, and fever: Take 5 fen of human earwax, 5 qian each of Stone Lotus Heart (*Nelumbinis Plumula*) and Ginseng Root (*Ren Shen*), 2 fen of Frankincense (*Ru Xiang*), 1 zi of Lamp Wick Flower (*Deng Hua*), and 1 fen of Cinnabar (*Dan Sha*).

[Names] Sinus Retraction.
Li Shizhen states: Nails are the surplus of tendons and the external manifestation of the Gallbladder. The *Ling Shu Jing* states: The Liver corresponds to nails. Thick nails with yellow color indicate a thick Gallbladder; thin nails with red color indicate a thin Gallbladder. Hard nails with blue-green color indicate a tense Gallbladder; soft nails with red color indicate a relaxed Gallbladder. Straight nails with white color and no lines indicate a straightforward Gallbladder; ugly nails with black color and many lines indicate a knotted Gallbladder.
[Properties and Flavor] Sweet, salty, neutral, non-toxic.
[Indications] Epistaxis: Scrape finely and insufflate into the nostril for immediate cessation. If unavailable, nails from others can be used (Chen Cangqi). Used to induce labor, expel the placenta, promote urination, treat hematuria, Yin-Yang exchange disease, traumatic wind-stroke, and remove corneal opacities (Li Shizhen). Powder from the husband's nails of a pregnant woman, instilled in the eyes, removes opacities (Chen Cangqi).
[Attached Prescriptions] Two old prescriptions, eighteen new prescriptions.
Method to Cut Off the Three Corpses: *Tai Shang Xuan Ke* records: Usually cut hand nails on Geng Chen day and foot nails on Jia Wu day. On the 16th day of the seventh lunar month annually, burn the nails to ash and ingest with water. This eliminates the Three Corpses and Nine Worms, named "Cutting Off the Three Corpses." Another version says: On Jia Yin day, the Three Corpses roam the hands, so cut hand nails; on Jia Wu day, they roam the feet, so cut foot nails.
Eliminate Hong Kong Foot (podagra/tinea pedis): Cut hand and foot nails on every Yin day, slightly cutting into the flesh, to treat Hong Kong Foot. (*Wai Tai Mi Yao*)
Traumatic wind-stroke: Stir-fry ten finger/toe nails in sesame oil until charred, grind, and mix with hot wine for sipping.
