【慈石】
气味：辛、寒，无毒。
主治：周痹（全身性痹痛），风湿，肢节疼痛，不能手持物品，肢体酸软消瘦，清除大热烦闷，以及耳聋。
（慈石产于泰山山谷及慈山山的北坡。现在的慈州、徐州以及南海旁边的山中都有出产。《南州异物志》说：涨海崎头水浅且多慈石，用铁叶加固的大船，到了这里都不能通过。由此说来，南海出产的尤其多。慈州出产的，每年进贡为最佳，能吸附铁器，虚连数十块铁片，或者一两斤刀具器具，旋转而不掉落，尤为优良。石头中有孔，孔中有黄赤色，上面有细毛，功效更好。土宿真君说：铁接受太阳之气，在最初生成时，卤石产生，经过一百五十年形成慈石，二百年孕育而成铁，所以慈石是铁的母亲精气。）
慈石颜色黑，味道辛，性质寒，大概是禀受了金和水的精气所生。周痹，在于血脉之中，真气不能周流全身。慈石能……（原文此处似有脱漏或语意未完，结合后文“济其火”等，意指其能调节阴阳气血）。风湿邪气侵袭肢节导致疼痛，致使手不能持物，脚酸软消瘦不能行走。“酸消”，就是“酸削”的意思。慈石禀受阳明、太阳的金水之气，来济助心火，阴与阳相交，也符合慈石引针下而升上的道理。
【石硫黄】
气味：酸、温，有毒。
主治：妇人阴部蚀烂，疽痔恶血，坚固筋骨，去除头部脱发，能够熔化金银铜铁等奇异之物。（“奇”字，怀疑是“等”字的误写。）
（石硫黄产于东海牧羊山谷及太行河西山中。现在南海各个番邦岭外州郡都有出产，然而不如从昆仑、雅州经海路运来的质量好。这是火石精华凝结而成，出产的地方一定有温泉，泉水也带有硫黄气味。以颗粒块状晶莹洁净光滑细腻，颜色黄，咀嚼无声的，最为好。夹杂泥土与石头的，不堪入药。）
硫黄色黄，形状像石头。黄色，是土的颜色。石头，是土的骨骼。遇到火就燃烧，其性质温热，这是禀受了火土相生的气化。火生于木，所以气味酸温，禀受火气而温通经脉，所以主治妇人的阴部蚀烂，以及疽痔恶血。禀受土石精华，所以能坚固筋骨。阳气生长则毛发发生，所以主治头部脱发。遇到火就燃烧，所以能够熔化金银铜铁等奇异之物。
[Cishi (Magnetite)]
Odor and Flavor: Pungent, Cold. Non-toxic.
Indications: Zhou Bi (generalized bi-syndrome), wind-dampness, pain in the limbs and joints, inability to hold objects, sensation of soreness and emaciation in the limbs, clearing severe heat and fullness/irritability, and deafness.
(Cishi is produced in the valleys of Mount Tai and on the shady slopes of Ci Mountain. It is currently found in Cizhou, Xuzhou, and mountains near the South Sea. The "Nanzhou Yiwu Zhi" states: At Qitou in the vast sea, the water is shallow and abundant with Cishi; large ships reinforced with iron leaves cannot pass through here. This indicates that the output from the South Sea is particularly abundant. Those from Cizhou are the best for annual tribute; they can attract iron, linking dozens of iron pieces or one or two jin of knives and utensils in rotation without falling, which is especially excellent. The stone has pores; within the pores is a yellow-red color with fine hairs on top, possessing superior efficacy. Tusu Zhenjun said: Iron receives the Qi of the Sun. In its initial generation, halite is produced. After 150 years, it becomes Cishi; after 200 years, it gestates into iron. Thus, Cishi is the maternal essence of iron.)
Cishi is black in color, pungent in flavor, and cold in nature, likely generated by inheriting the refined essence of Metal and Water. Zhou Bi resides within the blood vessels, where the True Qi cannot circulate fully. Cishi can... [text implies regulation of Qi/Blood]. Wind-damp pathogenic factors injuring the limbs and joints cause pain, resulting in the inability of hands to hold objects and feet being too sore and emaciated to walk. "Suan Xiao" (soreness and wasting) is synonymous with "Suan Xue" (sour and cutting sensation). Cishi inherits the Metal-Water Qi of the Yangming and Taiyang meridians to assist/control Fire, allowing Yin to intersect with Yang, consistent with the principle of Cishi attracting needles downward yet rising upward.
[Shi Liuhuang (Sulfur)]
Odor and Flavor: Sour, Warm. Toxic.
Indications: Erosion of the female yin, carbuncles, hemorrhoids with foul blood, strengthening tendons and bones, treating alopecia capitis, and capable of melting gold, silver, copper, iron, and other substances. ("Qi" is suspected to be a typo for "Deng" meaning "etc.")
(Shi Liuhuang is produced in the Muyang Valley of the East Sea and in the mountains west of the Taihang River. It is now found in various regions beyond the Ling Mountains in the South Sea, but those imported via ship from Kunlun and Yazhou are of superior quality. This is the结 (condensation) of the essence of fire stones; places of production must have hot springs, and the spring water also carries a sulfur odor. Pieces that are crystalline, clean, smooth, yellow in color, and silent when chewed are best. Those mixed with soil and rock are unsuitable for medicinal use.)
Sulfur is yellow in color and stone-like in shape. Yellow is the color of Earth. Stone is the bone of Earth. It flames upon contact with fire, and its nature is warm-hot, inheriting the Qi transformation of Fire generating Earth. Fire is born from Wood; therefore, its odor and flavor are sour and warm. By inheriting Fire Qi, it warms the meridians, thus indicating indications for erosion of the female yin, as well as carbuncles and hemorrhoids with foul blood. By inheriting the essence of Earth and Stone, it strengthens tendons and bones. When Yang Qi grows, hair occurs; thus, it treats alopecia capitis. Being able to flame upon contact with fire, it can melt gold, silver, copper, iron, and other substances.
