有毒。
土黄主治枯瘤、赘疣、痔疮、乳房疾病及饮食积滞，以及各类疮疡恶肉（《本草纲目》）。【味】辛、酸。【性】热。【炮制】（李时珍说）取砒石二两、木鳖子仁、巴豆仁各半两、砂二钱，研为细末，与木鳖子油、石脑油调和成一块，用油纸包裹埋入土坑内四十九日，取出劈成小块，装入瓷器中收藏。【解释】（独孤滔说）土黄是雄黄的炮制品。
金刚石主治磨水涂抹于汤火烫伤处，或制成钗饰佩戴，可辟除邪恶毒气（《本草纲目》）。【名称】金刚钻、削玉刀（李时珍说）其砂石可以钻孔玉石、修补瓷器，所以称为“钻”。【产地】（李时珍说）产于西番、天竺等国。（葛洪《抱朴子》说）扶南国出产金刚石，生于水底石上。（周密《齐东野语》说）相传产于西域及回纥高山顶上，鹰隼粘带后吞食入腹，粪便遗落在河北沙碛之间，不知是否属实。（《元中记》说）大秦国出产金刚，又名削玉刀，大的长约一尺，小的如稻黍，穿在环中可以刻玉。观此可知金刚有非常大的，番僧将其作为佛牙供奉。（《十洲记》）记载西海流沙中有昆吾石，加工后做成剑，像铁一样光亮如水精，切割玉石如泥，这也是极大的金刚。又有兽类貘及啮铁狡兔，都能吃铁，它们的粪便都可以用来制作兵器。切玉详见兽部貘条之下。【采集时间】（采）于夏秋季节，趁天气炎热，人可潜入水中采集。【用途】可以刻玉（周密《齐东野语》说）玉工攻玉，以恒河之砂配合金刚钻镂刻。【质地】形状像钟乳石，体质似紫石英，又像鼠屎。【颜色】青黑色，像石头也像铁。【性质】非常坚硬，即使铁锤敲击也不能损伤。【炮制】如果觉得钝了，就烧红后冷却定形，就会重新锋利。【禁忌】（葛洪《抱朴子》说）用羚羊角扣击金刚石，则它像冰一样消融瓦解。（《丹房鉴源》说）紫背铅能粉碎金刚钻。【伪品鉴别】想要辨别真伪，烧红后淬入醋中，如果依然不酥碎的就是真品。○（《元中记》说）金刚石最坚硬，而羚羊角又能克制它，由此可以领悟嗜欲足以乱真，所以西方人以金刚比喻佛性，以羚羊角比喻烦恼。
Toxic.
Tuhuang (Earth Yellow) treats withered tumors, warts, hemorrhoids, breast diseases, and food stagnation, as well as various sores with foul flesh (Compendium of Materia Medica). [Flavor] Acrid, sour. [Nature] Hot. [Processing] (Li Shizhen states) Take 2 liang of Pishishi (Arsenic Stone), half a liang each of Muguezi Ren (Seed of Momordica charantia) and Badou Ren (Seed of Croton tiglium), and 2 qian of Sha (Sand), grind into fine powder, mix with Muguezi You (Oil from Seed of Momordica charantia) and Shinao You (Naphtha oil) to form a paste, wrap in oil paper, bury in an earth pit for 49 days, take out, split into small pieces, and store in porcelain vessels. [Explanation] (Dugu Tao states) Tuhuang is the processed form of Xionghuang (Realgar).
Jingangshi (Diamond) treats water ground from it applied to scalds and burns, or worn as a hairpin to ward off evil and toxic vapors (Compendium of Materia Medica). [Names] Jingangzuan (Diamond Drill), Xiaoyudao (Jade-Cutting Knife) (Li Shizhen states) Its sand can drill jade and repair porcelain, hence called "Zuan" (Drill). [Origin] (Li Shizhen states) Produced in Xifan (Western Regions), Tianzhu (India), etc. (Ge Hong's *Baopuzi* states) Funan produces Jiangangshi, which grows on stones at the bottom of water. (Zhou Mi's *Qidong Yeyu* states) It is said to be produced in high mountains of the Western Regions and Uyghur lands; eagles carry it, swallow it, and excrete it in the sandy deserts north of the Hebei River; whether this is true is unknown. (*Yuan Zhong Ji* states) Daqin (Rome) produces Jiangang, also known as Xiaoyudao; large ones are about one chi long, small ones like rice grains, can be threaded through rings to carve jade. From this, we see that there are very large diamonds; Tibetan monks use them as Buddha teeth. (*Shizhou Ji*) records Kunwu stone in the flowing sands of the West Sea; when processed into swords, they are bright as iron and crystal clear, cutting jade like mud; these are also extremely large diamonds. There are beasts such as Mo (Tapir) and Jiaotu (Iron-biting Hare) that can eat iron, and their feces can be used to make weapons. See details on carving jade under the entry for Mo in the Beast section. [Harvesting Time] (Harvested) in summer and autumn, when the weather is hot, people can dive into the water to collect it. [Usage] Can carve jade (Zhou Mi's *Qidong Yeyu* states) Jade workers process jade using Ganges sand combined with a diamond drill. [Texture] Shape resembles Zhongru (Stalactite), body similar to Zishiyingshi (Purple Quartz), also resembling rat droppings. [Color] Bluish-black, like stone or iron. [Nature] Extremely hard; even if struck by an iron hammer, it cannot be damaged. [Processing] If it feels dull, heat it until red, then cool it to set, and it will become sharp again. [Contraindications] (Ge Hong's *Baopuzi* states) If struck by Lingyangjiao (Antelope Horn), it melts away like ice. (*Danfang Jianyuan* states) ZiBei Qian (Lead with Purple Back) can crush diamond drills. [Adulterant Identification] To distinguish authenticity, heat it until red, quench it in vinegar; if it remains intact and does not crumble, it is genuine. ○ (*Yuan Zhong Ji* states) Diamond is the hardest, yet Antelope Horn can overcome it; thus one can understand that desires are sufficient to confuse truth. Therefore, in the West, Diamond is used to metaphorize Buddha-nature, and Antelope Horn to metaphorize afflictions.
