主妇人产难，血闭，月水不通，阴阳隔塞。
此即今人所用射者耳，取烧赤内酒中，饮汁，亦以渗之，得古者弥胜，制镂多巧也。
味咸，无毒。主鬼疰、毒蛊、诸疰。生蜀郡，如金色者良。
今出蜀汉，似粗金，而大小方皆如棋子。又有铜牙亦相似，但色黑，内色小浅，不入药
用。金牙唯以合酒、散及五
疰丸，余方不甚须此也。
〔谨案〕金牙离本处入土水中，久皆色黑，不可谓之铜牙也。此出
汉中，金牙湍湍两岸入石间，
打出者，内则金色，岸崩入水，年久者皆黑。近南山溪谷茂州、维州，亦有胜于汉中也。
味辛，温。主疽疡，疥瘙，热气，恶疮，癞疾，死肌，堕眉，杀痔虫，去黑子息肉。疗

中山属代郡。今近山生石，青白色，作灶烧竟，以水沃之，则热蒸而解末矣。性至烈，

差也。

主治妇女难产，血闭不通，月经不行，阴阳气机阻隔闭塞。
这就是现在人们用来射箭的铜弩牙，将其烧红后放入酒中，饮用其汁液，也可以用来外敷渗透，效果比古代更好，因为现在的制作雕刻更加精巧。
味咸，无毒。主治鬼疰、毒蛊、各种疰病。产于蜀郡，颜色如金色的为佳。
现在出产于蜀汉地区，质地像粗金，大小形状都像棋子。又有铜牙也与此相似，但颜色发黑，内部颜色较浅，不入药使用。金牙只用于配合酒剂、散剂以及五疰丸，其他方剂不太需要用到它。
【考证】金牙离开产地进入泥土或水中，时间久了都会变黑，不能称之为铜牙。这种出自汉中，金牙在湍急河流两岸的石缝间，被打捞出来的，内部呈金色；岸边崩塌落入水中的，年代久远的都变黑了。靠近南山的溪谷茂州、维州等地，也有胜过汉中的。
味辛，性温。主治痈疽疮疡，疥癣瘙痒，热气，恶疮，癞疾，死肌，眉毛脱落，杀灭痔疮虫，去除黑痣息肉。治疗髓骨疽。又名恶灰，又名希灰。产于中山地区的山川河谷。
中山属于代郡。现在近山处出产石头，呈青白色，用作灶台烧完后，用水浇淋，就会热气蒸腾并分解成粉末。药性非常猛烈，人如果用酒送服，会导致腹痛腹泻，但治疗金创（金属利器造成的创伤）也非常有效。俗名石垩差也。
【考证】《别录》记载，人们用它治疗金创，止血效果显著。如果在五月五日采集蘩蒌、葛叶、鹿活草、槲叶、地黄叶、芍药叶、苍耳叶、青蒿叶，与锻石一起捣碎，做成鸡蛋大小的团块，晒干后研末，治疗各种疮疡生肌有极神奇的疗效。
味辛，微温。主治黑子、云疣、息肉、疽蚀，疥癣瘙痒。又名藜灰。产于方谷川泽。
这就是现在用来洗衣服的黄灰，将各种蒿草和藜草堆积焚烧炼制而成，药性猛烈，其中荻灰尤其猛烈。想要消除黑痣和疣赘，取这三种灰用水调和蒸煮后点涂即可去除，不可广泛使用，否则会腐蚀人的皮肉。
【考证】桑薪灰最适宜入药使用，治疗黑子和疣赘的功效胜过冬灰。用其煮小豆，能大幅消除水肿。然而冬灰本应是藜灰，其余草木灰并不正宗。又有青蒿灰，是焚烧蒿草制成的。柃灰，是焚烧……
Indicated for difficult childbirth in women, blood obstruction, amenorrhea, and blockage of the yin and yang qi mechanisms.
This is the copper bow trigger currently used by people. When heated red-hot and immersed in wine, the juice is drunk or applied externally to penetrate the lesion. Its efficacy is superior to that of ancient times due to more exquisite carving and manufacturing techniques.
Salty in flavor, non-toxic. Indicated for ghostly zhu (chronic infectious diseases attributed to supernatural causes), toxic gu (poisonous parasites), and various types of zhu diseases. Produced in Shu Commandery; those resembling gold in color are considered superior.
Currently produced in the Shu-Han region, resembling coarse gold, with sizes and shapes similar to chess pieces. There is also a "copper tooth" similar to this, but it is black in color with a lighter interior, and is not used in medicine. The "gold tooth" is only used in combination with wine preparations, powders, and the Wuzhu Wan (Five Zhu Pills); other formulas rarely require its use.
[Verification] When the gold tooth leaves its source and enters soil or water, it turns black over time and cannot be called a copper tooth. This variety comes from Hanzhong, where gold teeth are found in stone crevices along the banks of rapid streams, retrieved by washing; those internal to the stones retain a golden color, while those washed down from collapsing banks turn black after many years. Areas near the southern mountains, such as Xigou in Maozhou and Weizhou, also produce varieties superior to those from Hanzhong.
Pungent in flavor, warm in nature. Indicated for carbuncles and sores, scabies and pruritus, heat pathogens, malignant ulcers, leprosy-like diseases, necrotic tissue, loss of eyebrows, killing hemorrhoid worms, and removing black moles and polyps. Treats osteomyelitis of the marrow bone. Also known as Ehui (Evil Ash) and Xihui (Xi Ash). Produced in the mountain valleys of Zhongshan.
Zhongshan belongs to Dai Commandery. Currently, stones are found near mountains, appearing bluish-white. After being used to build stoves and burned, pouring water on them generates steam and breaks them down into powder. Its nature is extremely potent; if taken orally with wine, it causes abdominal pain and diarrhea, but it is very effective for treating metal-induced wounds (jin chuang). Colloquially known as Shi'e Cha.
[Verification] *Bielu* records that people use it to treat metal-induced wounds, with significant hemostatic effects. If collected on the fifth day of the fifth lunar month—along with leaves of Artemisia lactiflora, Pueraria lobata, Abutilon theophrasti, Quercus dentata, Rehmannia glutinosa, Paeonia lactiflora, Xanthium sibiricum, and Artemisia annua—and pounded together with calcined iron oxide (duanshi) into dumpling-sized balls, then dried and powdered, it has miraculous efficacy in promoting tissue regeneration for various ulcers.
Pungent in flavor, slightly warm. Indicated for black moles, cloud-like warts, polyps, ulcerative erosion, scabies, and pruritus. Also known as Li Hui (Lycium Ash). Produced in Fanggu river marshes.
This is the yellow ash currently used for laundry, made by burning accumulated mugwort and goosefoot plants. Its nature is potent, with reed ash being particularly strong. To eliminate black moles and warts, mix these three types of ash with water, steam, and apply topically to remove them. Do not use extensively, as it can corrode human skin and flesh.
[Verification] Ash from mulberry wood firewood is most suitable for medicinal use, surpassing Dong Hui (Winter Ash) in efficacy for treating black moles and warts. Boiling adzuki beans with it greatly reduces edema. However, Dong Hui should originally be Lycium ash; other grass ashes are not authentic. There is also Qinghao Hui (Artemisia annua Ash), made by burning mugwort. Ling Hui (Eurya Ash), made by burning...
