\r金屑\ph23.bmp\r，生益州。银屑，生永昌。陶隐居注云∶金之所生，处处皆有，梁、
益、宁三州多有，
出水沙中，作屑谓之生金。而银所出处，亦与金同，但皆生石中耳。苏恭以为银之与金，生
不同处。金又出水中。陈藏器云∶生金是毒蛇屎，常见人取金，掘地深丈余，至纷子石，石
皆一头黑焦，石下有金，大者如指，小犹若麻豆，色如桑黄，咬时极软，即是真金。麸金出
水沙中，毡上淘取，或鹅鸭腹中得之。注以陈说为非是。然今饶、信、南剑、登州出金处，
采得金亦多端，或有若山石状者，或有若米豆粒者，若此类未经火，皆可为生金。其银在矿
中，则与铜相杂，土人采得之，必以铅再三煎炼方成，故不得为生银也。故下别有生银条云
∶出饶州、乐平诸坑生银矿中，状如硬锡，纹理粗错自然者真。今坑中所得，乃在土石中，
渗溜成条，若丝发状，土人谓之老翁须，似此者极难得。方书用生银，必得此乃真耳，金屑
古方不见用者，银屑惟葛洪治痈肿五石汤用之。今人弥不用，惟作金银薄入药甚便，又金石
凌、红雪、紫雪辈，皆取金银取汁，此亦通用经炼者耳。
金屑，产于益州。银屑，产于永昌。陶隐居（陶弘景）注释说：金的产地，各地都有，梁州、益州、宁州三州较多，从水沙中产出，呈碎屑状的称为生金。而银的产地，也与金相同，只是都产于石矿中罢了。苏恭认为银和金的产地不同。金又产于水中。陈藏器说：生金是毒蛇的粪便，常见人们开采金子时，挖掘地面深达一丈多，到达纷子石层，石头都是一头黑焦，石头下面有金子，大的像手指，小的像麻豆，颜色像桑黄，咬起来极软，这就是真金。麸金产在水沙中，在毡上淘取，或者从鹅鸭腹中得到。陈藏器注解说上述说法是不对的。然而如今饶州、信州、南剑州、登州出产金子的地方，采得的金子也有很多种类，有的像山石形状，有的像米豆颗粒，像这类未经过火炼的，都可以作为生金。那些银在矿石中，则与铜混杂，当地百姓采得后，必须用铅反复煎炼才能成银，所以不能称为生银。所以下面另外有条目记载生银说：产于饶州、乐平各坑的生银矿中，形状像硬锡，纹理粗糙交错自然的为真品。如今坑中所获得的，是在土石中，渗透流淌形成条状，像丝发一样，当地人称之为老翁须，像这样的极其难得。医方中使用生银，必须得到这种才是真的。金屑在古代医方中不见使用，银屑只有葛洪治疗痈肿的五石汤中使用它。现在人更加不使用，只制作金银箔入药非常方便，另外金石凌、红雪、紫雪等药物，都是取金银汁液制成，这也是通用的经过炼制的材料罢了。
Gold Dust (Jin Xie), produced in Yizhou. Silver Flakes (Yin Xie), produced in Yongchang. Tao Hongjing (Tao Yinju) annotated: The sources of gold are found everywhere, particularly abundant in Liangzhou, Yizhou, and Ningzhou. It is extracted from river sand; when it appears as fragments, it is called raw gold (Sheng Jin). The sources of silver are similar to those of gold, but they are embedded within stone ores. Su Gong believed that the origins of silver and gold differ. Gold is also found in water. Chen Cangqi stated: Raw gold is actually the feces of venomous snakes. It is commonly observed that when people mine for gold, they dig more than one zhang deep into the ground until reaching "Fenzi" stones. These stones are blackened and scorched on one end, with gold located beneath them. The gold pieces vary in size, from as large as a finger to as small as hemp seeds. Their color resembles mulberry yellow; they are extremely soft when bitten, indicating genuine gold. Bran-like gold (Fu Jin) is found in river sands, collected by washing over felt, or obtained from the stomachs of geese and ducks. Chen Cangqi noted that these descriptions are incorrect. However, in current gold-producing areas such as Raozhou, Xinzhou, Nanjianzhou, and Dengzhou, the mined gold comes in various forms: some resemble mountain rocks, others look like rice or bean grains. Those unrefined by fire can all be considered raw gold. Silver found within ore deposits is often mixed with copper. Local miners must smelt it repeatedly with lead to refine it into silver; therefore, it cannot be classified as raw silver. Hence, a separate entry for raw silver states: Raw silver is sourced from mines in Raozhou and Leping. Genuine raw silver resembles hard tin, featuring naturally coarse and interlaced textures. What is currently obtained from pits is seeped and flowed within earth and stone, forming thread-like strands resembling hair, locally known as "Old Man's Beard." Such specimens are extremely rare. Medical texts require this specific form for the use of raw silver. Gold dust is rarely used in ancient prescriptions; silver flakes were only utilized in Ge Hong’s Five-Stone Decoction (Wushi Tang) for treating carbuncles and swellings. Contemporary practitioners seldom use them, preferring instead to process gold and silver into thin foils (Jinyin Bo) for medicinal convenience. Additionally, preparations such as Jinshi Ling, Red Snow (Hongxue), and Purple Snow (Zixue) utilize juices extracted from gold and silver, which are generally refined materials.
