味辛，平，有毒。主安五脏，定心神，止惊悸，除邪气，久服轻身长年。生永昌，
采无时。
银之所出处，亦与金同，但皆是生石中耳。炼饵法亦相似。今医方合镇心丸用之，不可
正服尔。为屑当以水银磨令
消也。永昌本属益州。今属宁州，绝远不复宾附。《仙经》又有服炼法，此当无正主疗，故
不为《本草》所载。古者名金
为黄金，银为白金，铜为赤金。今铜有生熟，炼熟者柔赤，而《本经》无用。今铜青及大钱
皆入方用，并是生铜，应在
下品之例也。
〔谨案〕银之与金，生不同处，金又兼出水中。方家用银屑，当取见成银薄，
以水银消之为泥。合硝石及盐
研为粉，烧出水银，淘去盐石，为粉极细，用之乃佳。不得已乃磨取屑耳。且银所在皆有，
而以虢州者为胜，此外多锡
秽为劣。高丽作帖者，云非银矿所出，然色
为器辟恶，乃为瑞物也。
味辛，寒，有毒。主疥瘙，痂疡，白秃，杀皮肤中虫虱、堕胎、除热。以傅男子阴，
阴消无气。杀金银铜锡毒，熔化还复为丹。久服神仙，不死。一名汞。生符陵平土，出于丹
砂。
畏磁石。今水银有生熟。此云生符陵平土者，是出朱砂腹中，亦别出沙地，皆青白色，
最胜。出于丹砂者，是今烧
粗末朱砂所得，色小白浊，不及生者。甚能消金银，使成泥，人以镀物是也。还复为丹，事
出《仙经》。酒和日曝，服之
长生。烧时飞着釜上灰，名汞粉，俗呼为水银灰，最能去虱。
〔谨案〕水银出于朱砂，皆因
热气，未闻朱砂腹中自出之者。
火烧飞取，人皆解法。南人又蒸取之，得水银少于火烧，而朱砂不损，但色少变黑耳。

味辛，性平，有毒。主治安养五脏，安定心神，停止惊悸，驱除邪气，长期服用可使身体轻盈、延年益寿。产于永昌，采集没有固定时间。
银的产地，也与金相同，但都是从矿石中产出。炼制服用的方法也相似。如今医方中配制镇心丸时使用它，但不能直接服用。制作银屑应当用水银研磨使其溶解。永昌原本属于益州。现在属于宁州，距离遥远不再向朝廷进贡。《仙经》中又有服用炼制的记载，这里应当没有主要的治疗作用，所以不被《本草》收录。古时候称金为黄金，银为白金，铜为赤金。现在的铜有生熟之分，炼制成熟的铜柔软呈红色，而《神农本草经》中没有使用。现在的铜青及大钱都是生铜，应该归在下品的类别中。
〔谨案〕银与金，产地不同，金又兼从水中产出。医家使用银屑时，应当选取现成的银薄片，用水银将其溶解成泥状。加入硝石和盐研磨成粉，烧制出水银，淘洗去除盐和石头，得到的粉末极细，使用效果才好。不得已的情况下才研磨取屑。而且银到处都有，以虢州出产的最好，其他地方多混杂锡等杂质，品质较差。高丽制作的银箔，声称不是从银矿中产出，然而其色泽能辟邪，被视为瑞物。

味辛，性寒，有毒。主治疥疮瘙痒，痂疡，白秃疮，杀灭皮肤中的虫虱，堕胎，清热。涂抹于男子阴部，会导致阴部萎缩、无精气。能杀灭金银铜锡的毒性，熔化后重新变为丹砂。长期服用可成神仙，不死。又名汞。产于符陵平坦的土地上，出自丹砂。
畏磁石。现在的水银有生熟之分。这里说产于符陵平坦土地上的，是出自朱砂内部的，也有另外出自沙地的，都是青白色，品质最好。出自丹砂的，是现在烧制粗末朱砂所得到的，颜色小白且浑浊，不如原生者好。非常能溶解金银，使其变成泥状，人们用来镀物就是这种方法。重新变为丹砂，事情出自《仙经》。用酒调和后在阳光下曝晒服用，可以长生。烧制时飞散附着在锅上的灰，名叫汞粉，俗称水银灰，最能去虱。
〔谨案〕水银出自朱砂，都是因为热气，没听说过朱砂内部自然产出的。火烧提取的方法，人们都了解。南方人又用蒸取的方法，得到的水银比火烧少，而朱砂不损坏，只是颜色稍微变黑而已。
[Mercury (Shuiyin) Entry]
Pungent in flavor, neutral in nature, toxic. It primarily nourishes the five Zang organs, calms the mind and spirit, stops palpitations and fright, expels pathogenic factors, and long-term use can make the body light and prolong life. Produced in Yongchang, collected at any time.
The source of silver is also the same as that of gold, but both are produced from stones. The method of refining and taking them internally is also similar. Currently, medical prescriptions use it when compounding Zhenxin Wan (Calming Heart Pill), but it cannot be taken directly. To make silver powder, one should grind it with mercury until it dissolves. Yongchang originally belonged to Yizhou. Now it belongs to Ningzhou, which is extremely far away and no longer submits tribute. The "Immortal Canon" also contains records of ingestion and refining methods; however, this [silver] likely lacks primary therapeutic effects, so it is not recorded in the "Bencao". In ancient times, gold was called Huangjin (Yellow Metal/Gold), silver was called Baijin (White Metal/Silver), and copper was called Chijin (Red Metal/Copper). Copper now exists in raw and refined states; refined copper is soft and red, while the "Shennong Bencao Jing" does not record its use. Current Tongqing (Copper verdigris) and large coins are all raw copper and should fall under the category of lower-grade herbs.
[Note] Silver and gold have different sources; gold also comes from water. When physicians use silver powder, they should take ready-made thin silver sheets, dissolve them into a paste using mercury. Mix with saltpeter and salt, grind into powder, heat to extract mercury, wash away the salt and stones, resulting in an extremely fine powder, which is best for use. Only if unavoidable should one grind to obtain flakes. Moreover, silver is found everywhere, but that from Guozhou is superior; others often contain impurities like tin and are inferior. Korean-made silver foil claims not to come from silver mines, yet its luster repels evil and is considered an auspicious object.
[Mercury (Shuiyin) Entry Continued]
Pungent in flavor, cold in nature, toxic. It primarily treats scabies and itching, crusty sores, tinea capitis (white baldness), kills insects and lice in the skin, induces abortion, and clears heat. Applied to the male genitals, it causes genital atrophy and loss of vital energy. It kills the toxicity of gold, silver, copper, and tin, melting them back into cinnabar. Long-term use leads to immortality. Also known as Geng (Mercury). Produced in flat lands of Fuling, originating from Zhusha (Cinnabar).
It fears Magnetite (Cishi). Currently, mercury exists in raw and refined forms. What is described here as produced in the flat lands of Fuling refers to that extracted from within Cinnabar, or separately from sandy soil; both are bluish-white and of the highest quality. That derived from Cinnabar is obtained by burning coarse Cinnabar powder today; it is pale white and turbid, inferior to the raw form. It effectively dissolves gold and silver into a paste, which people use for plating. Returning to become cinnabar is a matter recorded in the "Immortal Canon". Mixed with wine and sun-dried, it can be taken for longevity. The ash that flies up and adheres to the pot during heating is named Gongfen (Mercury powder), commonly called Shuiyinhui (Mercury ash), which is most effective against lice.
[Note] Mercury originates from Cinnabar due to heat; there is no hearing that it naturally emerges from within Cinnabar. The method of extraction by fire and sublimation is understood by everyone. People in the south also use steaming to extract it, yielding less mercury than fire extraction, without damaging the Cinnabar, only causing a slight darkening of color.
