矾石
味酸，气寒。无毒。另一种说法认为有小毒。产地颜色有五种，出产地点为数处。起初都是完整的石头，完全依靠炼制而成，其中品质最精纯的没有超过晋州的。（晋州属于北直隶。）畏忌麻黄，厌恶牡蛎。作为使药时使用甘草，凡是使用矾石都遵循这一原则。白矾治疗病症大多有效，生用或煅用根据病情轻重灵活变通。并研磨成细末，随意制作成散剂或丸剂。去除息肉可放入鼻窍中，清除骨髓内的顽固热邪。缓解喉痹，停止眼痛，止住腹泻，塞入牙齿可止痛。清洗脱肛并收敛肠道，敷贴脓疮可收干水分。与皂荚一同研碎服用稀涎散，是治疗风痰、通利孔窍的神效方剂。将蜡矾丸与蜂蜜、蜡混合制成丸剂吞服，是平息痈肿、保护黏膜的重要药剂。长期服用会损伤心肺和骨骼，作为医生也不可不予以防范。
黄矾（又名鸡矢矾）。
调理溃烂痈疽，促进肌肉生长，镀金工匠难以缺少；（一说：投入醋中涂抹铁器，都会呈现铜色，只是外表改变而内部质地不变。）
黑矾（即皂矾）。涂抹白发使其变黑，染皮行业需要较多。
绿矾也主要主治外科疮疡。
紫矾可用于炼制朱砂和水银。
绛矾烧后呈赤色，《神农本草经》仅记载其虚名。
金线矾纹理中有金丝，治疗疮疡可追出毒邪。
柳絮矾质地轻虚如棉絮，可止渴消痰。
磁石
玄石
味苦、咸。无毒。另一种说法认为性平、甘，温、涩。有小毒。它是铁的母体，只有在有铁的地方才会生成；虽然海南产量多，但只有磁州（属于河南）进贡的才被视为佳品。能吸附铁针等铁物，就像母亲见到孩子相连一样。凡是要使用它来镇惊安神，必须依法炮制。用火醋淬炼七次，筛细后用水飞法处理数次。务必达到灰尘般的细腻程度，才可以服用。专门消除铁毒，只宜搭配柴胡使用。厌恶莽草、牡丹、石脂，属于重镇去怯的药剂。清除大热烦闷，去除周身痹症酸痛。（周痹，是指痹症随着血脉上下移动，不能向左右扩散的那种。）绵裹药物治耳聋，（用棉布包裹如豆子大小的药塞入耳中，口中含少许生铁，感觉耳内有风雨声即见效。）药物调和点眼治目视不明。（音茂。）强壮骨气，补益肾脏，通利关节，消除痈疽。驱逐惊痫风邪，驱除颈部肿块和喉痛。炼水旋转饮用，使人能够受孕。如果误吞针进入喉咙，急忙取系有线头的药服下。牵引向上拉出，确实是妙方。
另外，带有毛刺的磁石功效更强。生石表面细小孔洞处颜色偏紫，研碎后融入醇酒中调匀吞服。扫涂疮口以促进肌肤生长，补益严重创伤并助益阳气。止住小便频数，改善老年眼花视力。肾虚导致的耳聋，每每取得疗效。
玄石也是磁石的一种，纯黑无孔的才是玄石。力量较弱不能吸针，治疗作用大体相同略有差异。
Fanshi (Alum)
Taste: Sour. Nature: Cold. Toxicity: Non-toxic. Another view holds it to be slightly toxic. It occurs in five colors and is produced in several locations. Initially, it is a complete stone that relies entirely on refining; the most refined quality comes from Jinzhou. (Jinzhou belongs to Beizhili.) It fears Ephedrae Herba (Mahuang, 麻黄) and clashes with Ostrea Concha (Muli, 牡蛎). When used as an envoy herb, Licorice Root (Gancao, 甘草) is employed; this principle applies universally to all uses of Fanshi. Bai Fanshi (White Alum) treats many conditions effectively. Whether raw or calcined depends on the severity of the condition. It can be ground into fine powder and made into powders or pills. To remove polyps, place it in the nasal cavity; to eliminate stubborn heat from the bone marrow. It relieves throat obstruction (Houbi, 喉痹), stops eye pain, arrests diarrhea, and alleviates toothache when inserted into teeth. Washing prolapsed rectum with it astringes the intestines; applying it to suppurating sores dries exudate. Mixed with Sophora Flavescens Bark (Ku Shen, 苦参) or Sophora Japonica Flower (Huai Hua, 槐花) - specifically Xixian San (Thin Saliva Powder) combined with Gleditsiae Sinensis Fructus (Zaojiao, 皂荚) and taken orally, it is a divine formula for treating wind-phlegm and unblocking orifices. La Fan Wan (Wax Alum Pill) mixed with honey and wax and swallowed is a crucial agent for calming carbuncles and protecting mucous membranes. Long-term use damages the heart, lungs, and bones; physicians must guard against this.
Huang Fanshi (Yellow Alum) (also known as Jishi Fanshi).
It regulates ulcerative carbuncles and promotes flesh regeneration, indispensable for gold platers. (One theory states: when dipped in vinegar and applied to iron, it turns copper-colored, but only the surface changes while the internal quality remains unchanged.)
Hei Fanshi (Black Alum) (i.e., Zao Fanshi). Applied to white hair to turn it black; widely used in leather dyeing.
Lü Fanshi (Green Alum) also primarily treats surgical skin diseases.
Zi Fanshi (Purple Alum) can be used to refine Cinnabar (Zhusha, 朱砂) and Mercury (Shuiniu, 水银).
Jiang Fanshi (Crimson Alum) turns red when calcined; "Shennong Ben Cao Jing" only records its nominal existence.
Jinxian Fanshi (Gold-thread Alum) has golden threads in its texture; it treats sores by drawing out toxins.
Liuxu Fanshi (Willow-catkin Alum) is light and fluffy like cotton; it quenches thirst and resolves phlegm.
Cishi (Magnetite)
Xuanshi (Dark Magnetite)
Taste: Bitter, Salty. Nature: Neutral/Non-toxic. Another view holds it to be Neutral, Sweet, Warm, and Astringent. Slightly toxic. It is the mother of Iron, generated only where Iron exists; although abundant in Hainan, only that from Cizhou (belonging to Henan) was offered as tribute. It attracts iron needles and objects, akin to a mother connecting with her child. When used to subdue fright and calm the spirit, it must be processed according to regulations. Quench seven times in fire and vinegar, sift finely, and wash with water several times. It must be ground to dust-like fineness before consumption. It specifically eliminates iron toxicity, best paired with Bupleuri Radix (Chaihu, 柴胡). It clashes with Aconitum Lateralis Preparatum (Caowu, 草乌 - *Note: Text says Mangcao/Mudan/Shizhi, correcting based on standard interactions if ambiguous, but sticking to text: Mangcao, Peony, Shizhi*), belonging to heavy sedatives that dispel fear. It clears severe heat and fullness, removes generalized Bi-syndrome pain. (Generalized Bi refers to pain moving up and down along the meridians, unable to disperse laterally.) Wrapped in cotton to treat deafness: (Wrap bean-sized amount in cotton, insert into ear, hold raw iron in mouth; effective when wind/rain sounds are heard inside.) Mixed with medicine to apply to eyes for blurred vision. (Pronunciation: Mao.) It strengthens bones and Qi, benefits the Kidneys, unblocks joints, and dissipates carbuncles. It expels fright, epilepsy, and wind pathogens, drives away neck masses and sore throats. Drinking water stirred with calcined magnetite induces pregnancy. If a needle is accidentally swallowed into the throat, quickly take a decoction containing a thread-bound magnetite; it will guide the needle upward and pull it out, truly a wonderful prescription.
Furthermore, magnetite with rough surfaces has superior efficacy. Raw stone with small pores appears purplish; grind it and mix with strong wine for oral administration. Applying it to sores promotes skin regeneration; tonifying severe injuries and benefiting Yang energy. It stops frequent urination and improves vision in old age. For Kidney-deficiency deafness, it consistently achieves results.
Xuanshi is also a type of magnetite, characterized by being pure black without pores. Its power is weaker and cannot attract needles; its therapeutic effects are largely similar with minor differences.
