【扁青】
味甘，性平，无毒。主治目痛，明目，跌打损伤及痈肿，金创久不愈合，破除积聚，解除毒瓦斯，使精神清爽，去除寒热风痹，以及男子尿道中的各种疾病，补益精气。长期服用可身体轻健，延缓衰老。产于朱崖山谷、武都、朱提，采集没有固定时间。《仙经》和世俗方书中都没有使用此药。朱崖郡以前属于交州，位于南海之中，晋代已废除该郡建制，朱提郡现在属于宁州。（参考《新修本草》第十页，《大观本草》卷三，《政和本草》第九十六页）
【石胆】
味酸、辛，性寒，有毒。主治明目，目痛，金创，各种癫痫痉挛，女子阴部蚀痛，石淋（泌尿系结石），寒热往来，崩中下血（妇科出血性疾病），各种邪气毒瓦斯，使人能够生育，消散症积，治疗咳逆上气，以及鼠瘘恶疮。经过炼制后饵服可延缓衰老，长期服用增加寿命，成仙得道。能化铁为铜，生成金银。又名毕石，又名黑石，又名棋石，又名铜勒。产于羌道山谷羌里句青山。在二月庚子日、辛丑日采集。（水英为其辅佐药，畏惧牡桂、菌桂、芫花、辛夷、白薇）。《仙经》中有此处记载，但世俗方书很少使用，这种药几乎绝迹。现在人们偶尔有采集的，其颜色青绿，形状像琉璃但有白色纹理，容易破碎折断。梁州、信都不再出产，世面上常用青色矾石来冒充，完全不像。《仙经》中又称其为立制石。（参考《新修本草》第十一页，《大观本草》卷三，《政和本草》第八十九页）
【云母】
味甘，性平，无毒。主治皮肤死肌，中风寒热。如在车船中晕眩不适，去除邪气，安五脏，补益精气，明目，降气，坚固肌肉，接续断骨，补中气，治疗五劳七伤，虚损少气，止痢。长期服用身体轻健，延年益寿，容颜润泽不老，耐寒暑，志向高远如神仙。又名云珠，颜色多赤红。又名云华，五色俱全。又名云英，颜色多青。又名云液，颜色多白。又名云砂，颜色青黄。又名磷石，颜色正白。产于泰山山谷、庐山，以及琅琊北定山石间，二月采集。（泽泻为其辅佐药，畏惧甲虫类药材，反流水，厌恶徐长卿）。
按《仙经》记载，云母共有八种：对着太阳看，颜色青白多黑的叫云母，颜色黄白多青的叫云英，这六种都可以好地服用，但各有适宜的季节；那些黯黯纯黑，有纹路斑斑像铁一样的，叫云胆，颜色杂黑且质地强肥的叫地涿，这两种都不能服用。炼制有方法，必须精细；否则，进入腹部会严重害人。现在虚劳家用的丸散中只用捣碎筛选，非常不妥。琅琊在彭城东北，青州也有。现在江东地区只认为庐山的云母最好，用沙土培育它，经过岁月生长而成。现在炼制时如果用矾石则会使云母柔烂，这也是相畏的效果。百草上的露水，胜过东流水，也使用五月茅屋的溜水。（参考《新修本草》）
[Bianqing]
Taste: Sweet. Nature: Neutral. Toxicity: Non-toxic. Indications: Ophthalmalgia (eye pain), improving vision, traumatic injuries with fractures and abscesses, non-healing metallic wounds, breaking up accumulations and masses, detoxifying poisonous vapors, benefiting the spirit and mind, expelling wind-cold-damp bi syndrome, and various diseases of the male urethra, tonifying essence. Long-term use makes the body light and delays aging. Habitat: Valleys of Zhuya, Wudu, Zhuti. Harvesting time: No fixed season. Note: Not used in *Xianjing* or secular prescriptions. Zhuya Commandery formerly belonged to Jiaozhou, located in the South China Sea; abolished in the Jin Dynasty. Zhuti Commandery currently belongs to Ningzhou. (Ref: *Xinxiu Bencao* p.10, *Daguan Bencao* Vol.3, *Zhenghe Bencao* p.96)
[Shidan / Copper Sulfate]
Taste: Sour, Pungent. Nature: Cold. Toxicity: Toxic. Indications: Improving vision, ophthalmalgia, metallic wounds, various epilepsy spasms, female genital erosion/pain, lithiasis (stone strangury), alternating chills and fever, metrorrhagia and metrostaxis, various pathogenic toxic vapors, promoting fertility, dissipating mass formations, treating cough and rebellious qi, and rat-sores/malignant ulcers. After refining and taking as an electuary, it delays aging; long-term use increases longevity and leads to immortality. It can transform iron into copper and generate gold and silver. Aliases: Bishi, Heishi, Qishi, Tongle. Habitat: Qianglijuqingshan Valley in Qiangdao. Harvesting time: Gengzi and Xinchou days in the second lunar month. Interactions: Facilitated by Shuiying; incompatible with Mugui, Jungui, Yuanhua, Xinyi, Baiwei. Note: Mentioned in *Xianjing*, rarely used in secular prescriptions, nearly extinct. Current specimens are greenish-blue, resembling glass with white veins, brittle. Unavailable in Liangzhou and Xindu. Often substituted with green alum stone, which bears no resemblance. *Xianjing* also calls it Lizhishi. (Ref: *Xinxiu Bencao* p.11, *Daguan Bencao* Vol.3, *Zhenghe Bencao* p.89)
[Yunmu / Mica]
Taste: Sweet. Nature: Neutral. Toxicity: Non-toxic. Indications: Dead skin/flesh, wind-stroke with chills and fever, motion sickness in vehicles/boats, expelling pathogenic factors, calming the Five Viscera, tonifying essence, improving vision, descending rebellious qi, firming muscles, healing fractures, tonifying the Middle Jiao, treating five labors and seven injuries, deficiency with shortness of breath, stopping dysentery. Long-term use makes the body light, prolongs life, beautifies complexion, resists cold and heat, elevates spiritual aspiration like a deity. Aliases: Yunzhu (mostly red), Yunhua (five colors present), Yunying (mostly green), Yunye (mostly white), Yunsha (green-yellow), Linshi (pure white). Habitat: Valleys of Mount Tai, Mount Lu, and between rocks at Beiding Mountain in Langya. Harvesting time: Second lunar month. Interactions: Facilitated by Zexie; incompatible with certain beetles, contrary to Liushui, adverse to Xuchangqing.
Note from *Xianjing*: There are eight types of Yunmu. Facing the sun, those that are green-white with much black are named Yunmu; those yellow-white with much green are named Yunying. These six types are good for consumption but have specific seasonal timings. Those that are dark pure black with patterns like iron are named Yundan; those mixed black and strong/fat are named Dizhuo. These two types must not be consumed. Refining requires meticulous methods; otherwise, ingestion causes severe harm. Currently, practitioners of deficiency-labor conditions only crush and sieve it for pills and powders, which is inappropriate. Langya is northeast of Pengcheng; Qingzhou also has it. In Jiangdong, only Mount Lu mica is considered superior, cultivated in sand soil over years. Refining with Alum Stone (*Fan Shi*) softens it, demonstrating incompatibility. Dew on hundred herbs surpasses East-flowing Water; May rainwater from thatched roofs is also used. (Ref: *Xinxiu Bencao*)
