（《纲目》）
【释名】猩红、紫粉霜。时珍曰∶昔人谓水银出于丹砂，熔化还复为朱者，即此也。名
亦由此。
【集解】时珍曰∶胡演《丹药秘诀》云∶升炼银朱，用石亭脂二斤，新锅内熔化，次下
水银一斤，炒作青砂头，炒不见星。研末罐盛，石板盖住，铁线缚定，盐泥固济，大火 之。
待冷取出，贴罐者为银朱，贴口者为丹砂。今人多以黄丹及矾红杂之，其色黄黯，宜辨之。
真者谓之水华朱。每水银一斤，烧朱一十四两八分，次朱三两五钱。
【气味】辛，温，有毒。
【主治】破积滞，劫痰涎，散结胸，疗疥癣恶疮，杀虫及虱，功同粉霜（时珍）。
【发明】时珍曰∶银朱乃硫黄同汞升炼而成，其性燥烈，亦能烂龈挛筋，其功过与轻粉
同也。今厨人往往以之染色供馔，宜去之。

[Names] Xinghong (Scarlet Red), Zifen Shuang (Purple Powder Frost). Li Shizhen stated: In the past, people believed that quicksilver (Shuiyin) originated from cinnabar (Dansha), and when melted, it reverted to vermilion; this substance is exactly that. Its name derives from this origin.
[Collection and Explanation] Li Shizhen stated: Hu Yan's "Secrets of Alchemical Pills" records: To refine Yin Zhu (Silver Cinnabar), use two jin (approx. 1 kg) of Shitingzhi (Styptic Stone), melt it in a new iron pot, then add one jin of quicksilver, stir-fry until it becomes Qing Sha Tou (Green Sand Head), stirring until no silver specks are visible. Grind into powder, store in a jar, cover with a stone slab, bind tightly with iron wire, seal firmly with salt mud, and calcine over high fire. After cooling and removing, the material adhering to the jar wall is called Yin Zhu, while that adhering to the mouth is called Dansha. Nowadays, many people adulterate it with Huang Dan (Litharge) and Fan Hong (Alum Red), resulting in a dull yellow color; this should be distinguished. The genuine product is called Shuihua Zhu (Water Flower Vermilion). For every one jin of quicksilver, fourteen liang eight fen of Yin Zhu can be produced, and three liang five qian of inferior Yin Zhu.
[Flavor and Properties] Acrid, warm, toxic.
[Indications] Breaks up stagnation, attacks phlegm-fluids, dissipates chest binding, treats scabies, tinea, and malignant sores, kills parasites and lice. Its efficacy is similar to Fen Shuang (Powder Frost) (Li Shizhen).
[Elucidation] Li Shizhen stated: Yin Zhu is formed by sublimating sulfur and mercury together. Its nature is dry and fierce; it can also cause gum rot and tendon contraction. Its harmfulness is comparable to that of Qing Fen (Calomel). Nowadays, cooks often use it for coloring food, which should be abandoned.
[Attached Prescriptions] Twenty new prescriptions.
Infant internal hookworm with excessive crying: Take half a qian of Yin Zhu, one qian of Ruxiang (Frankincense), and one qian of Wei Suan (Baked Garlic), grind into powder, and mix into pills the size of millet seeds. For infants half a year old, administer five pills each time, washed down with Bohe Tang (Mint Decoction). (From *Xin Jian*)
Yin Du (Yin Toxicity) in men and women: Take one qian of Yin Zhu and one qian of Qing Fen. Use one bulb of Dusu (Single-clove Garlic) grown for five days, mash and mix to form a cake. Apply to the palm of the hand; for men, apply to the left hand, for women to the right hand. Hold both hands together, place below the genitals. When qi returns and sweating occurs, recovery ensues. Survival is indicated if there is slight breath in the mouth. (From Tang Yao's *Jingyan Fang*)
Phlegm-qi Chest Binding: Heding Dan (Crane Top Pill): Regardless of yin or yang, deficiency or excess, use decoctions of Xianxiong Tang (Trap the Chest Decoction) and Xiexin Tang (Drain the Heart Decoction) that have been stir-fried. Take half a liang of Yin Zhu and one liang of Mingfan (Alum), grind together. Place fire in an ironer, hold the medicine in a clay cup, melt it, and quickly scrape and roll into pills. Take one qian per dose, mixed with true tea and a little ginger juice. If a faint sound is heard over the heart, the chest binding will disperse spontaneously. This method does not disturb the zang-fu organs nor damage the true qi, because Mingfan resolves phlegm and Yin Zhu breaks stagnation. (From Zeng Shirong's *Huoyou Quanshu*)
Edema with normal bowel movements: Take half a liang of Yin Zhu and four liang of Huangqi (Sulfur). Grind into powder, make pills the size of wutong seeds using wheat paste. Take thirty pills per dose with water. (From *Puji Fang*)
Sore throat: Take equal parts of Yin Zhu and Haipiaoxiao (Cuttlefish Bone) powder. Blow into the throat to induce salivation/phlegm discharge. (From *Ji Jiu Fang*)
Flame Erysipelas: Mix Yin Zhu with egg white and apply. (From Li Lou's *Guai Zheng Fang*)
Scalds and burns: Grind Yin Zhu finely, mix with vegetable oil, and apply. Two applications lead to cure. (From *Duoneng Bisshi*)
Back carbuncle: Take equal parts of Yin Zhu and Bai Fan (White Alum), decoct in water for warm washing. Then moxa far away with Sangchai Huo (Mulberry wood fire) three times daily; highly effective. (From *Jiu Ji Fang*)
Fish-umbilical Ding sore (carbuncle), red on all sides, black in the center: Take Yin Zhu, mix with water to form pills. Take one pill per dose, washed down with warm wine. Named Zouma Dan (Running Horse Pill). (From *Puji Fang*)
Syphilis (Yangmei Du Chuang): Take equal parts of Yin Zhu and Guanxiang (Official Fragrance/Musk substitute). Grind into powder, roll into paper cigarettes, light as a lamp, and place in a bucket. Inhale the smoke through the nose, once daily, cured in seven days. Another prescription: Take two qian of Yin Zhu, one qian of Hai'ercha (Child's Tea/Catechu), one qian of Longguaxiang (Dragon Hanging Incense), one qian of Zaojiaozi (Soap Bean Seed), grind into powder. Use as above. Another prescription: Take one qian of Yin Zhu and one qian of Qingfen, one liang of Huangla (Yellow Wax), and one liang of Qingyou (Clear Oil), melt and mix. Spread on oiled paper and apply; the crust will fall off naturally.
Bone and tendon pain: Take three qian of Xinghong (Scarlet Red/Yin Zhu) and four qian of Kufan (Burnt Alum). Grind into powder, make three paper twists. Every morning, take one twist, dip in oil, ignite, and moxa the navel. Cover with blankets and lie down to induce sweating. (From *Zuoya Qifang*)
Chronic stubborn sores that do not heal: Take one qian of Yin Zhu, five fen of Qiannian Dixia Duanshi (Ancient Underground Forge Stone), five qian of Songxiang (Pine Rosin), and one liang of Xiangyou (Sesame Oil). Grind into powder. Melt and spread on paper to apply. (From *Yingji Liangfang*)
Sores that do not close: Same prescription as above.
Blood Wind Sores appearing on the thighs, caused by damp-toxicity transforming into wind: Melt one liang of Huangla (Yellow Wax), add one liang of Yin Zhu, stir and spread on paper, prick holes, and apply. (From *Jianbian Fang*)
Yellow-water Damp Sores: Mash Yin Zhu and Yanmei (Salted Plum) together and apply. (From *Jixuan Fang*)
Tinea with worms: Mix Yin Zhu and Niu Gu Sui (Ox Marrow), dilute with Tongyou (Tung Oil), and rub on. (From *Yi Fang Jiangyao*)
Head Lice: Soak Yin Zhu in vinegar, comb hair daily. Wrap Yin Zhu in paper, burn under a bowl, collect the smoke residue with tea water, and rub the scalp. Wrap the head overnight; by morning, all lice will be dead. (From *Jide Tang Fang*)
