禀地中阴水之气以生，故味甘、咸、微寒，无毒。咸能入血，甘能补血，寒能补
热，所以入血分以治金疮痈肿之患也。
无名异，治金疮折损，用之以醋摩涂，去瘀止痛，生肌长肉。
禀西方刚利之性，故味辛，平，有毒。善能治木平肝而降，亦能镇心辟邪而安，故
为利惊气、散风热、安魂魄、镇心平肝之用。然质重性刚，服之伤肌损骨。故古今以
难求死者，服金一二钱，则腹剜心痛肠胃如裂而毙。惟作箔用乃无伤耳。
金屑，除邪杀毒，却热驱烦，安魂魄，养心神，和血脉。禁癫疾狂走，止惊悸风
痫。幼科镇心丸，衣以金箔，饰即平肝，以治风，复镇心以除热。金星石，治肺损咳嗽吐红。
银屑，除谵语恍惚不睡，止热狂惊悸发痫，定志养神，镇心明目，安五脏，辟诸

忘，补齿缺落。
铜禀土中阴气以生，青则其英华秀出于外所结，然必仗咸酸之味而成。故味苦、
酸、涩，气寒，无毒。酸入肝而能敛。所以合金疮止血。苦寒能除风热，所以去肤赤息
肉。苦能泄结，所以又主气心痛吐风痰也。
铜青，乃铜之精华。治妇人血气心痛，洗眼目风热肿痛，敛金疮，吐风痰，去肤赤
除息肉，喉痹口疮并资，神效。
Wumingyi (Black Copper Ore): Born by inheriting the Yin water Qi from the earth, its taste is sweet and salty, with a slightly cold nature, and it is non-toxic. Salty flavor enters the blood level; sweet flavor nourishes blood; cold nature clears heat. Therefore, it enters the blood level to treat injuries caused by metal weapons (Jinchuang) and sores/swellings.
Wumingyi treats injuries from metal weapons and fractures. When ground with vinegar and applied topically, it removes blood stasis, alleviates pain, and promotes tissue regeneration.
Jinbo (Gold Foil): Inheriting the sharp and rigid nature of the West, its taste is pungent, nature is neutral, and it is toxic. It excels at pacifying the Liver and directing Qi downward, as well as calming the Heart, expelling evil, and stabilizing the spirit. Thus, it is used to benefit against fright Qi, dissipate wind-heat, calm the soul, and pacify the Liver while settling the Heart. However, being heavy in substance and rigid in nature, ingestion damages muscles and bones. Hence, throughout history, those who sought death by taking it would die if they ingested even one or two qian, suffering from abdominal excavation-like pain, heartache, and intestines splitting asunder. Only when made into foil for external use does it cause no harm.
Jinxie (Gold Dust) dispels evil and toxins, eliminates heat and irritability, calms the soul, nourishes Heart spirit, and harmonizes blood vessels. It prevents manic wandering due to epilepsy, stops palpitations and wind-phlegm seizures. In pediatric Zhenxin Wan (Calming the Heart Pill), coated with gold foil, the decoration itself serves to pacify the Liver to treat wind, and simultaneously settle the Heart to clear heat. Jinxingshi (Venus Stone) treats lung damage manifesting as cough and hemoptysis.
Yinxie (Silver Dust) eliminates delirium, trance, and insomnia; stops heat-induced mania, palpitations, and seizures; stabilizes will and nourishes spirit; settles the Heart and brightens the eyes; anchors the Five Zang organs; and repels various evils. Yinxingshi (Silver Star Stone) is treated using the same method as Jinxingshi. Yingao (Silver Paste) consists of tin foil, silver foil, and mercury combined; it specifically treats Heart deficiency causing forgetfulness and fills missing or lost teeth.
Tongqing (Verdigris): Copper inherits the Yin Qi from Earth; the green color is the essence blooming outwardly, but it must rely on salty and sour flavors to form. Thus, its taste is bitter, sour, and astringent; its nature is cold, and it is non-toxic. Sour flavor enters the Liver and has an astringent property. Therefore, it aids in stopping bleeding from metal weapon injuries. Bitter-cold nature dispels wind-heat, thus removing skin redness and polyps. Bitter flavor drains stagnation, thus also managing Qi-stagnation chest pain and vomiting of wind-phlegm.
Tongqing is the essence of copper. It treats Blood-Qi chest pain in women, washes away wind-heat swelling and pain in the eyes, contracts wounds from metal weapons, induces vomiting of wind-phlegm, removes skin redness and polyps, and is effective for throat obstruction (Houbi) and mouth ulcers, yielding miraculous results.
