咸苦温，小毒。
发明 头垢乃相火之余气结成，专开郁结之气。乳痈初起， 灰，酒服即消，以其善祛
胃中积垢也。
甘咸平，无毒。
发明 乳汁治目之功甚捷。目得血而能视，乳即血之源也。用以点眼岂不相宜，老人服
食尤良。但脾虚易泻者勿食。日中曝干入参苓丸服尤为合宜。
甘咸小毒。
发明 爪乃肝气之余，其性锐利，故能催生下胞衣，利小便，治尿血及阴阳易病，破伤
风，去目翳。刮末治鼻衄 之立止。又能治乳蛾。用爪指甲不拘多少 为末，硼砂、白矾各
一钱、西牛黄一分、乌梅、白梅肉各五枚，共捣如泥，含弹大一丸，痰大涌出，三四丸即愈
。但其方酸收太速，不无萌发之患，莫若探吐顽痰迅扫病根为愈。
甘咸热有毒。
发明 牙乃肾之标、骨之余。痘疮倒 用人牙散。因痘疮为风寒秽气所触而变黑倒
，用此 灰，以酒麝达之，窜入肾经，发出毒瓦斯，乃劫剂也。若伏热在心，昏冒不省人事，
及气虚色白痒塌不能作脓，热痱紫泡之证，正宜凉血解毒。苟误用之则郁闷声哑，反成不救
，临证审诸。
甘咸寒无毒。造法，用大竹截段，两头留节，削去外皮，傍钻一孔，用甘草细
末入满于中，以蕉扇柄削圆塞孔，冬至浸大粪池内，立春后取出，悬风处晾干，取用。又法
如前制竹，不入甘草，但用蕉扇柄或杉木塞孔，浸粪池中，以取其汁与金汁无异，仅供一时
取用，不能久藏。粪清亦解瘟热诸毒。又误食毒菌、枫树上菌、及过食银杏，胀闭欲死者，
悉能解之。并解砒石、野葛、野芋等毒。即家芋三年不收，花开如莲者亦能杀人，急取灌吐
，方可得生。
发明 人中黄取粪土之精，以解天行狂热温毒发斑最捷。然汁则性速而能下泄，甘草制
者则性缓而能解毒。兼治河豚菌毒，一切恶疮灾病，用人中黄、酒、大黄末等分，无灰酒服
，须臾泻利，毒即随出。虽大渴不可饮水，饮水则毒邪不散而难救也。急切不可得，以粪坑
代之。
[Head Scum]
Salty, bitter, warm, slightly toxic.
Invention: Head scum is formed from the residual qi of ministerial fire and is specifically used to open up stagnant qi. For early-stage mastitis (acute suppurative disease of the breast), burning head scum into ash and taking it with wine can dissipate the swelling, as it excels at removing accumulated filth in the stomach.
[Milk]
Sweet, salty, neutral, non-toxic.
Invention: Milk has a very rapid effect in treating eye diseases. The eyes require blood nourishment to see, and milk is the source of blood. Is it not appropriate to use it for eye drops? It is especially beneficial for the elderly when ingested. However, those with spleen deficiency prone to diarrhea should avoid consuming it. Drying it under the noon sun and incorporating it into Ren Shen Ling Zhu Wan (Ginseng and Poria Pill) is particularly suitable.
[Nails]
Sweet, salty, slightly toxic.
Invention: Nails are the remainder of liver qi; their nature is sharp, thus they can induce the expulsion of the placenta, promote urination, treat hematuria, yin-yang exchange disease (relapse of cold damage due to sexual intercourse after recovery), tetanus, remove corneal nebulae, and stop epistaxis immediately when applied as powder. They can also treat tonsillitis. Take an unspecified amount of fingernails, grind them into powder, mix with one qian of Borax, one qian of Alum, one fen of Western Musk (Calculus Bovis), five dried dark plums, and five pieces of white plum flesh. Pound together into a paste, form a pill the size of a bullet, and hold in the mouth. Phlegm will surge out profusely; three or four pills will cure the condition. However, this formula's astringent action is too rapid, potentially causing hidden dangers. It is better to induce vomiting of stubborn phlegm to swiftly sweep away the root of the disease.
[Human Teeth]
Sweet, salty, hot, toxic.
Invention: Teeth are the external marker of the kidneys and the remainder of bones. Ren Ya San (Human Tooth Powder) is used for inverted smallpox (where pustules fail to rise). Since smallpox turns black and inverts due to invasion by wind-cold and turbid qi, using this medicine burned to ash, guided by wine and musk into the kidney meridian, expels toxic vapors. This is a drastic method. If there is latent heat in the heart causing coma and unconsciousness, or if there is qi deficiency with pale complexion, itching, collapse, inability to suppurate, or heat prickly heat with purple blisters, cooling blood and resolving toxicity is indicated. Misusing human teeth will cause depression and hoarseness, rendering the condition incurable. Clinical judgment must be prudent.
[Ren Zhong Huang]
Sweet, salty, cold, non-toxic.
Preparation: Cut a section of large bamboo, retaining nodes at both ends, peel off the outer skin, drill a hole on the side, fill it completely with fine Licorice powder, plug the hole with a rounded banana fan handle, soak it in a large fecal pit on the Winter Solstice, retrieve it after the Start of Spring, hang it in a ventilated place to dry, then use. Another method: prepare the bamboo tube as above but do not add licorice; plug the hole with a banana fan handle or cedar wood, soak in the fecal pit to obtain the juice, which is identical to Jin Zhi (Golden Juice), suitable only for immediate use and cannot be stored long-term. Fecal supernatant can also resolve various toxins from epidemic heat. Additionally, it resolves poisoning from poisonous mushrooms, fungi on maple trees, and excessive consumption of ginkgo nuts causing abdominal distension and closure nearing death. It also resolves poisoning from realgar, wild kudzu vine, and wild taro. Even cultivated taro left unharvested for three years, blooming like lotuses, can be fatal; urgent induction of vomiting upon ingestion can save life.
Invention: Ren Zhong Huang extracts the essence of feces and earth, making it most effective for resolving epidemic febrile diseases characterized by high fever and macular eruptions caused by warm toxins. However, the juice acts rapidly and promotes downward purgation, whereas that processed with Licorice acts mildly and resolves toxicity. It treats pufferfish and mushroom poisoning, and all malignant sores and calamitous diseases. Mix equal parts of Ren Zhong Huang, wine, and Rhubarb powder; take with non-ash wine. Diarrhea occurs shortly after, and toxins are expelled. Although extreme thirst may occur, water should not be drunk, as drinking water prevents the dispersion of toxic pathogens and makes rescue difficult. If Ren Zhong Huang is urgently unavailable, fecal pit water can serve as a substitute.
