味辛，性平，有毒。归入心、肺二经。主要功效为安定心神，平息惊悸，镇摄癫狂，清除邪热。
按语：金银之所以能入肺经，是因为它们同属金类。其性质沉重，能够制约心脏（火脏）轻扬浮越的特性，所以也能入心经。过量服用必然导致中毒，可以用鹧鸪肉来解毒。
味辛，性微寒，有毒。未记载归经。主要功效为催吐逆气，治疗癫狂，止痛，促进肌肉生长。
按语：黄丹是由熬炼铅制成的。铅本是水中的金，最能克制火邪。呕吐、发狂等证候，哪一样不是由火邪引起？既然能制火，为何不能治愈呢？
味辛，性寒，无毒。未记载归经。主要功效为治疗各种痈肿及诸般毒邪，以及腐烂的肉芽。杀灭三虫，破除症结积聚。
按语：胡粉又名粉锡，实际上也是由化炼铅制成的。能够破除结聚、杀灭寄生虫，大概也是依靠其沉降坠下的功效吧。
味苦涩，性平，有微毒。未记载归经。主要功效为收敛金创伤口，治疗视力昏暗，止血杀虫，能够去除腐肉。
按语：铜青即铜绿，原本是醋淋在铜上而获得的精华。醋具有收敛作用，所以能收敛疮口、止血；它去除腐肉的作用，也是醋的功效。
味甘涩，性平，无毒。归入心、肺二经。主要功效为治疗癫痫、狂乱，解除进入腹部的各种毒素，治疗蛇和狗咬伤，镇安心神，明亮眼目，可用于清洗膝部溃疡，随手即可痊愈。
按语：铁浆是浸泡铁器所得的液体，颜色青黑，可以用来染黑丝织品。其本质属金，适宜归于肺经；其性质沉潜，适宜镇摄心神。明目和治疗漆疮，都是依靠其伐木（金克木）的功效。铁锈也可以敷贴疮毒。这也是因为发散在外的事物具有消散的含义吧。
味辛，性寒，有毒。未记载归经。主要功效为治疗疹子结痂、溃疡，头部秃疮及皮肤病，杀灭虱子，堕胎绝育，解除金银铜锡的毒性。将其熔化后重新炼制成丹药服用，据说可以成仙不死。但畏惧磁石和砒霜。
按语：水银治疗虫疹等证候，确实是因为它的毒性所致。又能杀灭五金之毒，大概是因为它性质阴柔，能将五金溶解为泥状罢了。水银进入耳朵能食尽脑髓，进入肌肉会导致全身关节挛缩，导致阴阳断绝。其性质滑利沉重，极易侵入肌肉，必须极其谨慎。它能排出死胎，可以灌服。
雷公说：凡是草本植物中提取的，以及朱漆中含有的，都不可使用。经过其他药物炮制过的不要使用，曾经包裹过死尸或半生半死者不要使用。如果在朱砂中产出的，其水银色欲呈红色，收集后用葫芦盛装，以免遗失。如果先用紫背天葵和夜交藤的自然汁液两种药材共同煮沸一个时辰，其毒性自然消退。如果要炼制十两水银，只需用煎煮好的两种汁液各七镒，混合煮沸至足量为止。
Pungent in flavor, neutral in nature, toxic. Enters the Heart and Lung meridians. Primarily serves to calm the Spirit (Shen), stabilize palpitations and fright, subdue mania and epilepsy, and eliminate pathogenic heat.
Note: The reason gold and silver enter the Lung meridian is due to their elemental affinity with Metal. Their nature is heavy and dense, capable of restraining the light and ascending qualities of the Fire organ (Heart); therefore, they also enter the Heart meridian. Overconsumption will inevitably lead to poisoning, which can be antidoted with Partridge meat.
Pungent in flavor, slightly cold in nature, toxic. Meridian tropism is not recorded. Primarily serves to induce vomiting for rebellious Qi, treat mania and epilepsy, relieve pain, and promote tissue regeneration.
Note: Huangdan (Lead Oxide) is produced by smelting Lead. Lead is essentially "Metal within Water," possessing a strong capacity to suppress Fire. Since conditions such as vomiting and mania are largely driven by Fire, how could they fail to heal given this suppressing action?
Pungent in flavor, cold in nature, non-toxic. Meridian tropism is not recorded. Primarily serves to treat various carbuncles, swellings, and diverse toxins, as well as necrotic flesh. It kills three types of parasites and breaks up accumulations and masses.
Note: Hufen (Basic Lead Carbonate), also known as Fenxi, is actually derived from smelted Lead. Its ability to break up stagnation and kill parasites likely stems from its heavy and descending properties.
Bitter and astringent in flavor, neutral in nature, slightly toxic. Meridian tropism is not recorded. Primarily serves to consolidate traumatic wounds, treat blurred vision, stop bleeding, kill parasites, and remove necrotic tissue.
Note: Tongqing (Verdigris) is the essence obtained by applying vinegar to copper. Vinegar has astringent properties; thus, it consolidates sores and stops bleeding. Its ability to remove necrotic tissue is also attributed to the action of vinegar.
Sweet and astringent in flavor, neutral in nature, non-toxic. Enters the Heart and Lung meridians. Primarily serves to treat epilepsy and manic confusion, resolve various toxins ingested into the abdomen, treat snake and dog bites, calm the Spirit, brighten the eyes, and cleanse knee ulcers, leading to immediate healing.
Mixed with oil for topical application, it can cover malignant sores and scabies; ground with garlic and applied, it treats spider bites.
Note: Tiejiang (Ferrous Sulfate solution) is the liquid obtained from soaking iron. It is blue-green in color and can dye silk black. Its substance belongs to Metal, making it suitable for the Lung meridian; its nature is sinking, making it suitable for calming the Heart. Brightening the eyes and treating lacquer dermatitis are both due to its Wood-subduing (Metal overcoming Wood) function. Tielu (Iron Rust) can also be applied to sores and toxins. This is because substances acting on the exterior possess the meaning of dispersal.
Pungent in flavor, cold in nature, toxic. Meridian tropism is not recorded. Primarily serves to treat rash crusts, ulcers, alopecia capitis, and skin diseases; kill lice; induce abortion and sterilization; and detoxify gold, silver, copper, and tin. When melted and re-refined into pills and taken, it is said to confer immortality. However, it is inhibited by Magnetite (Cishi) and Arsenic Trioxide (Pishuang).
Note: The efficacy of Shuiyin (Mercurius, Mercury) in treating worm-related rashes and other conditions is indeed due to its toxicity. Its ability to neutralize the toxicity of the five metals is likely because its Yin and soft nature can dissolve metals into mud. If it enters the ear, it can consume the brain entirely; if it enters the flesh, it causes contraction of all joints, leading to the severance of Yin and Yang. Its nature is slippery and heavy, easily penetrating the flesh, requiring utmost caution. It can expel dead fetuses and may be administered via enema.
Lei Gong stated: Substances extracted from herbs or found in vermilion lacquer should not be used. Those processed by other medicines should not be used. Those that have wrapped corpses or half-dead bodies should not be used. If produced within Cinnabar (Zhusha), the mercury appears reddish in hue. After collection, store it in a gourd to prevent loss. If first boiled together with the natural juices of Zibeitiankui (Basella rubra) and Yejiaoteng (Polygonum multiflorum vine) for one shichen (two hours), its toxicity will naturally dissipate. To process ten taels of mercury, use seven yi of each of the two decocted juices, mix them, and boil until sufficient.
