\r金牙\ph57.bmp\r，生蜀郡，今雍州亦有之。《本经》以如金色者良，而此物出于溪
谷，在蜀、汉江岸石
间打出者，内即金色，岸摧入水年久者多黑。葛洪治风毒厥，有大、小金牙酒，但浸其汁而
饮之。古方亦有烧淬去毒入药者。孙思邈治风毒及鬼疰、南方瘴气、传尸等，各有大、小金
牙散之类是也。又有铜牙，亦相似，而外黑色，方书少见用者。小金牙酒，主风疰百病，虚
劳湿冷缓不仁，不能行步，近人用之多效，故着其法云∶金牙、细辛、地肤子、莽草、干
地黄、蒴 根、防风、附子、茵芋、续断、蜀椒各四两，独活一斤，十二物，金牙捣末，别
盛练囊，余皆薄切，并金牙共内大绢囊，以清酒四斗渍之，密泥器口，四宿酒成，温服二合
，日三。渐增之。
\r锻石\ph58.bmp\r，生中山川谷，今所在近山处皆有之。此烧青石为灰也，又名石锻。
有两种∶风化、水
化。风化者，取锻了石，置风中自解，此为有力。水化者，以水沃之，则热蒸而解，力差劣
。古方多用合百草团末，治金创殊胜。今医家或以腊月黄牛胆，取汁搜和，却内胆中，挂之
当风百日，研之更胜草叶者。又败般茹灰，刮取用亦同。又冬灰，生方谷川泽。浣衣黄灰，
烧诸蒿藜积聚炼作之。今用灰，多杂薪蒸乃不善。惟桑薪灰，纯者入药绝奇。古方以诸灰杂
锻石熬煎，以点疣、痣、黑子等，丹灶亦用之。又锻铁灶中灰，主坚积，古方二车丸用之。
灶中对釜月下黄土，名伏龙肝。灶额上墨，名百草霜，并主消化积滞，今人下食药中多用之
。铛下墨、梁上尘，并主金创。屋尘煤，治齿断肿出血。东壁土，主下部疮、脱肛，皆医家
常用，故并见此。伤寒黑奴丸，用釜底墨、灶突墨、梁上尘三物，同合诸药，盖其功用亦相
近矣。

金牙，产于蜀郡，如今雍州也有出产。《神农本草经》认为颜色如金色者品质优良，而这种物品出自溪谷，在蜀地、汉江岸边的石缝间开采出来，内部呈现金色，若岸边岩石崩塌落入水中年代久远者则多呈黑色。葛洪治疗风毒厥证，有大金牙酒和小金牙酒，只需浸泡取其汁液饮用即可。古方中也有将其烧淬以去除毒性后入药使用的。孙思邈治疗风毒及鬼疰（一种具有传染性的慢性消耗性疾病）、南方瘴气、传尸（类似肺结核的传染病）等，各有大金牙散、小金牙散之类的方剂。还有铜牙，形态相似但外部呈黑色，医方书中较少使用。小金牙酒，主治风疰百病，以及虚劳湿冷导致的肢体麻木不仁、行走困难等症状，近代人使用此方多有效验，因此记录其制法如下：金牙、细辛、地肤子、莽草、干地黄、蒴藋根、防风、附子、茵芋、续断、蜀椒各四两，独活一斤。以上十二味药，将金牙捣成粉末，单独装入丝织袋中，其余药物均切成薄片，与装金牙的袋子一同放入大绢袋内，用清酒四斗浸泡，密封容器口，经过四个夜晚酒即制成，每次温服二合，每日三次，逐渐增加剂量。
锻石，产于中山地区的山谷，如今靠近山的地方都有出产。这是将青石烧制成灰，又名石锻。有两种类型：风化和水化。风化的方法，是取烧过的锻石，放置在风中自然分解，这种方法效力较强。水化的方法，是用浇水淋洒它，则热气蒸腾而分解，效力较差劣。古方中多用它与百草混合研成粉末，治疗金属利器造成的创伤特别显著。现在的医家有时用腊月里黄牛胆的胆汁，取汁调和锻石，再放回胆中，挂在通风处一百天，研磨后使用比加草叶更好。又有败蒲灰，刮取使用也相同。还有冬灰，产于方谷川泽。浣衣黄灰，是将各种蒿草藜类积聚起来炼制成的。现在使用的灰，大多掺杂了柴薪灰烬，效果不好。只有桑木燃烧的纯灰，入药效果极佳。古方中将各种灰与锻石混合熬煎，用来点涂疣、痣、黑子等，炼丹术中也使用它。另外，锻铁灶中的灰，主治坚积（体内形成的坚硬肿块），古方“二车丸”中使用它。灶台中对着锅底下方的黄土，名为伏龙肝。灶台额头上的烟墨，名为百草霜，都主治消化积滞，现在人常在下食消食药中加入这些成分。锅底的墨、房梁上的灰尘，都主治金属利器造成的创伤。屋顶尘埃煤渣，治疗牙齿断裂肿胀出血。东壁土，主治下部疮疡、脱肛，这些都是医家常用的药物，所以一并记载于此。伤寒黑奴丸，使用釜底墨、灶突墨、梁上尘这三种物质，与其他药物配合，大概是因为它们的功能相近。

Jin Ya (Gold Tooth), produced in Shu Commandery, and currently also found in Yongzhou. *Shennong Bencao Jing* states that those resembling gold in color are of superior quality. This substance originates from streams and valleys; it is extracted from stone crevices along the banks of the Shu region and the Han River. Internally, it appears golden, whereas stones that have collapsed into the water over many years often turn black. Ge Hong treated wind-toxin jue syndrome with Da Jin Ya Jiu (Large Gold Tooth Wine) and Xiao Jin Ya Jiu (Small Gold Tooth Wine), simply by soaking the material and drinking the infusion. Ancient prescriptions also included methods of calcining and quenching to remove toxicity before incorporating it into medicine. Sun Simiao treated wind-toxin, Gui Zhu (ghostly infection, a contagious chronic wasting disease), southern miasma, and Chuan Shi (transmitting corpse, similar to tuberculosis) using formulas such as Da Jin Ya San (Large Gold Tooth Powder) and Xiao Jin Ya San (Small Gold Tooth Powder). There is also Tong Ya (Copper Tooth), which is similar in appearance but black on the exterior, and is rarely used in medical texts.
Xiao Jin Ya Jiu (Small Gold Tooth Wine) primarily treats wind-zhu (wind-infection) and various diseases, as well as deficiency-fatigue caused by damp-cold leading to numbness and inability to walk. Recent practitioners have found it effective, so its preparation method is recorded as follows: Jin Ya (Gold Tooth), Xixin (Asarum Root), Difuzi (Kochia Fruit), Mangcao (Artemisia Argyi Leaf), Gadihuang (Dried Rehmannia Root), Shuogen (Polygonatum Rhizome), Fangfeng (Saposhnikovia Root), Fuzi (Aconite Lateral Root), Yinyu (Epimedium Herb), Xuduan (Dipsacus Root), Shujiao (Sichuan Pepper) each 4 liang, and Duhuo (Angelica Pubescens Root) 1 jin. These twelve ingredients: crush Jin Ya into powder and place separately in a silk bag. Slice the remaining herbs thinly, and put them together with the Jin Ya bag into a large linen bag. Soak in 4 dou of clear wine, seal the vessel mouth tightly with mud, and let stand for four nights until the wine is ready. Warm and take 2 he per dose, three times daily, gradually increasing the dosage.
Duan Shi (Calcined Stone), produced in the valleys of Zhongshan, and currently available in areas near mountains everywhere. This is ash made by burning bluestone, also known as Shi Duan. There are two types: Fenghua (Wind-weathered) and Shuihua (Water-treated). For Fenghua, take the calcined stone and leave it in the wind to decompose naturally; this method yields stronger efficacy. For Shuihua, pour water over it, causing heat and steam to facilitate decomposition, but the efficacy is inferior. Ancient prescriptions often mixed it with powdered herbs to treat metal wounds effectively. Modern physicians sometimes use bile from a yellow ox gallbladder collected in the twelfth lunar month, mixing it with the stone, returning it to the gallbladder, hanging it in a ventilated place for one hundred days, and grinding it for use, which is considered superior to adding herbal leaves. Alternatively, ashes from decaying cattail roots can be scraped and used similarly. Dong Hui (Winter Ash) is produced in Fanggu river marshes. Huanyi Huanghui (Yellow Ash for Laundry) is made by burning accumulated mugwort and chenopodium. Current usage often involves ash mixed with firewood residues, which is less desirable. Only pure ash from mulberry wood is excellent for medicinal use. Ancient prescriptions boiled various ashes with Duan Shi to apply to warts, nevi, and black spots, and it was also used in alchemy. Furthermore, ash from iron-smelting furnaces treats Jian Ji (hard accumulations); it is used in the ancient prescription Er Che Wan (Two-Cart Pill). The yellow earth beneath the pot in the furnace is named Fulong Gan (Dragon Liver). Soot from the top of the stove is named Baicao Shuang (Hundred Herbs Frost); both promote digestion and resolve stagnation, and are commonly added to digestive aids today. Mo from the bottom of a wok and dust from roof beams both treat metal wounds. Dust and coal from roofs treat swollen and bleeding gums. Earth from the east wall treats lower body sores and rectal prolapse. These are all commonly used by physicians, hence they are recorded here. Shanghan Heinu Wan (Black Slave Pill for Cold Damage) uses Mo from the wok bottom, Mo from the stove flue, and dust from roof beams combined with other herbs, likely because their functions are similar.
