性平，微毒。治疗妇女血气心痛，用于金创止血，明目，去除皮肤上的赤色息肉。生铜表面都会产生青色物质，青色是铜的精华，即铜器上绿色的部分，其中北庭出产的最好。治疗眼疾时需淘洗后使用。（新补充内容见陈藏器、日华子记载。）
陈藏器说：陶隐居认为青铜不入药方使用。我认为青铜能明目，去除皮肤赤色息肉，治疗金创，止血，入水不腐烂，使疮口呈现青黑色。生铜和熟铜表面都有青色，这就是铜的精华，颗粒大的叫空青，次一级的叫空绿。而铜青特指仅在铜器表面形成的绿色物质。
经验方：治疗痰涎壅盛，突然中风不能言语，备急大效。碧琳丹：取生绿矾二两洗净，在乳钵中研细，用水溶解后过滤去石渣澄清，与绿矾粉一起在慢火上熬干。制作时要选择辰日辰时在辰位上进行，再次研匀后加入一分麝香共同研磨，用糯米糊调和制成如弹子大小的丸药，阴干。如果是中风患者，每丸分两次服用，用薄荷酒研磨送下。治疗瘫缓及一切风证，用朱砂酒研磨化开送服，等待吐出涎沫，颜色呈青碧色，泻出恶物。又一方：治疗小儿绿云丹：不分剂量，研细如粉，用醋面糊调和制成如鸡头大小的丸药。凡是患此病的人，刚感觉不适就立即用薄荷酒磨下一丸服用，不久就会呕吐，其涎液像胶一样，让人用手拔除，待吐完后，神效。
（井底沙）性质极冷，主治汤火烫伤。
千金方：蝎子螫人。用井底泥涂抹患处，变温了就更换。肘后方：睡觉时突然昏迷不醒，不要用火光照射，用火照会致死。只需用力咬其脚后跟及足大脚趾甲边缘，并多向其面部唾唾液即可救活。用井底泥涂目毕，令人垂头于井中，呼其姓名便起。又一方：治疗孕妇感染时疫传染病令胎儿不受伤害，取井底泥敷在心下。
Nature: Neutral, slightly toxic. Indications: Treats heart pain due to blood and qi disorders in women; used for metal wounds to stop bleeding; brightens the eyes; removes red polyps on the skin. Green patina forms on all raw copper; this green substance is the essence of copper, specifically the green layer found on copper vessels. The variety from Beiting is considered the best. For treating eye conditions, it must be washed thoroughly before use. (Newly supplemented content recorded by Chen Cangqi and Ri Huaizi.)
Chen Cangqi stated: Tao Hongjing believed that bronze should not be used in prescriptions. However, I observe that bronze can brighten the eyes, remove red skin polyps, treat metal wounds, stop bleeding, does not rot when submerged in water, and causes wounds to turn greenish-black. Both raw and refined copper develop a green surface layer, which constitutes the essence of copper. Larger granules are called Kongqing (Hollow Malachite), while smaller ones are called Konglv. Tongqing (Copper Green) specifically refers only to the green substance formed on the surface of copper vessels.
Empirical Formula: For treating excessive phlegm-fluid retention and sudden stroke with aphasia, offering great emergency efficacy. Bilin Dan (Jade-Like Pill): Take 2 liang of raw Lvshi (Green Alum), wash it clean, grind it finely in a mortar, dissolve it in water, filter out insoluble residues to clarify, and then slowly boil the mixture with the alum powder until dry. The preparation should be conducted at the Chen hour (7-9 AM) on a Chen day, facing the Chen direction. Grind uniformly again, add 1 fen of Shexiang (Musk), and mix well. Bind with rice flour paste into pills the size of a bullet, and dry in the shade. For stroke patients, divide one pill into two doses, grinding each dose with Bohe Jiu (Mint Wine) for administration. For paralysis, flaccidity, and all wind syndromes, dissolve the pill in Zhusha Jiu (Cinnabar Wine) and administer. Wait for the patient to expectorate phlegm; if the phlegm is greenish-blue and foul matter is purged, it indicates efficacy. Another Formula: Xia'er Lüyun Dan (Infant Green Cloud Pill): Dosage is not fixed. Grind finely into powder, bind with vinegar-flour paste into pills the size of a chicken head. For any infant suffering from this condition, administer one pill ground in Mint Wine as soon as symptoms appear. Vomiting will occur shortly after; the expelled phlegm will be gelatinous. Assist by manually extracting it. This method is highly effective after vomiting ceases.
(Jingdi Sha / Mud from the Bottom of a Well) Nature: Extremely cold. Main indications: Treats scalds and burns.
Qianjin Fang (Essential Prescriptions Worth a Thousand Gold): For scorpion stings. Apply mud from the bottom of a well to the affected area; replace it when it warms up. Zhouhou Fang (Prescriptions Kept in the Sleeve for Emergencies): For sudden unconsciousness during sleep. Do not illuminate with fire, as exposure to light may cause death. Instead, bite firmly at the heel and the edge of the big toenail, and spit saliva onto the face frequently to revive the patient. After applying well-bottom mud to the eyes, have the person hang their head into the well and call their name to restore consciousness. Another Formula: To protect the fetus when a pregnant woman contracts seasonal epidemic diseases, apply mud from the bottom of a well to the epigastrium (below the heart).
