【铁衣】
气味平和。味道辛、甘。无毒。主治风热引起的恶疮、溃疡、疽疮。以及痂疥等病邪在皮肤中的病症。（用醋炒后研磨）
铁衣（生铁落）气味平和，禀受自然界秋季下降的金气。归入手太阴肺经。味道辛、甘，无毒，得自大地金土之味。归入足阳明燥金胃土经。其气味降多于升，性质沉重，颜色黑，属阴。肝为风木之脏，风热疮疽、痂疥属于肝火症状。铁衣气平可以平抑肝火；味甘可以缓解热势，所以能主治这些病症。皮肤是肺的外合部位。病邪在皮中，是因为气不能收敛。铁衣之所以能主治，是因为其气平能够收敛气机。《素问》记载使用铁落治疗狂症，狂症是肝木的病证，所以取金气来克制它。
制方：
铁衣同白芍、甘草、丹皮、枸杞子、牛蒡子、茯神、木瓜、远志配伍。治疗狂症。同白芍、北五味子、炮姜、枸杞子、肉桂、甘草配伍。治疗小儿惊风。
【丹砂】
气味微寒。味道甘。无毒。主治身体五脏百病。滋养精神。安定魂魄。益气明目。驱杀精魅邪恶鬼怪。长期服用可通神明、不老。（用水飞法处理）
丹砂气味微寒，禀受自然界初冬寒水之气。归入足少阴肾经。味道甘，无毒，得自大地中正的土味。归入足太阴脾经。颜色赤红而生出水银，归入手少阴心经。盖因心乃火脏而藏阴精。其气味降多于升，质地重而味薄，属阴。心和肾，是人身的水火。天地的作用在于水火。水火安和，则人身天地定位。丹砂，色赤质重可以镇安心火；气寒可以补益肾水。水升火降，心肾相交，身体五脏的疾病都能痊愈。心是生命的根本，神的居所。肾是气的源头，精的处所。心肾相交，则精神相互滋养。随神往来的叫做魂。并精出入的叫做魄。精神交相滋养，则魂魄自然安定。味甘补益脾气。脾为后天之本，气来源于天，充养于谷食。后天脾胃纳谷，所以能益气。心病多涉及肝脏。心火不亢盛，则肝血上奉于目，所以又能明目。色赤具备南方阳明的色泽。阳明能辟除阴幽之气，所以能驱杀精魅邪恶鬼怪。长期服用通神明、不老的原因在于：心所藏的是神明。长期服用丹砂，则心火清静。火清则血液充盈，所以心神虚灵不昧，面色光彩华丽。
制方：
丹砂一两，同人参、茯神、甘草各二钱，山药、马豆各四钱，青黛、僵蚕各一钱，冰片一分，制成丸药。名为安神丸。治疗小儿惊症。同生地、当归、白茯苓、甘草、川黄连配伍。名为朱砂安神丸。具有安神清热功效。
[Tieyi (Iron Rind / Calcined Iron)]
Qi is neutral. Flavor is pungent and sweet. Non-toxic. Primarily treats malignant sores, ulcers, carbuncles, and gangrene caused by wind-heat. Also treats scabies and crusts where pathogenic qi resides in the skin. (Stir-fry with vinegar and grind).
Tieyi possesses a neutral Qi, inheriting the descending Metal Qi of autumn from Heaven. It enters the Hand-Taiyin Lung Meridian. Its flavor is pungent and sweet, non-toxic, deriving from the Metal and Earth flavors of the Earth. It enters the Foot-Yangming Stomach Meridian (Dryness-Metal) and Spleen Meridian (Earth). The descending aspect of its Qi and flavor outweighs the ascending. Its nature is heavy, its color black, belonging to Yin. The Liver is the organ of Wind-Wood. Wind-heat sores, carbuncles, scabies, and crusts are symptoms of Liver Fire. The neutral Qi can pacify the Liver; the sweet flavor can alleviate heat, thus it serves as the primary treatment. The skin is the exterior correspondence of the Lung. Pathogenic qi residing in the skin indicates a failure of Qi to consolidate. Tieyi treats this because its neutral Qi can consolidate Qi. The *Suwen* records the use of Tieluo (Fallen Iron) to treat mania. Mania is a disorder of Liver Wood, hence the Metal Qi is taken to control it.
Prescription:
Tieyi combined with Baishao (Radix Paeoniae Alba), Gancao (Radix Glycyrrhizae), Danpi (Cortex Moutan), Qizi (Fructus Lycii), Niubangzi (Fructus Arctii), Fushen (Poria with Hostwood), Mugua (Fructus Chaenomelis), and Yuanzhi (Radix Polygalae). Treats mania. Combined with Baishao, Beiweizi (Fructus Schisandrae), Paojiang (Rhizoma Zingiberis Preparatum), Qizi, Rougui (Cortex Cinnamomi), and Gancao. Treats pediatric convulsions.
[Dansha (Cinnabar)]
Qi is slightly cold. Flavor is sweet. Non-toxic. Primarily treats various diseases of the five viscera and hundred ailments of the body. Nourishes spirit. Calms hun and po. Benefits Qi and brightens the eyes. Expels demons, evil spirits, and malevolent entities. Long-term consumption promotes spiritual clarity and longevity. (Processed by water levigation).
Dansha possesses a slightly cold Qi, inheriting the Cold-Water Qi of early winter from Heaven. It enters the Foot-Shaoyin Kidney Meridian. Its flavor is sweet, non-toxic, deriving from the central Earth flavor of the Earth. It enters the Foot-Taiyin Spleen Meridian. Its red color generates Mercury, entering the Hand-Shaoyin Heart Meridian. The Heart is a Fire organ but stores Yin essence. The descending aspect of its Qi and flavor outweighs the ascending. Its texture is heavy and flavor thin, belonging to Yin. The Heart and Kidney are the Water and Fire of the human body. The function of Heaven and Earth lies in Water and Fire. When Water and Fire are harmonious, the position of Heaven and Earth in the human body is established. Dansha, being red and heavy, can anchor Heart Fire; its cold Qi can benefit Kidney Water. Water ascends and Fire descends, Heart and Kidney interact, and diseases of the five viscera are healed. The Heart is the root of life and the dwelling of Shen (Spirit). The Kidney is the source of Qi and the repository of Jing (Essence). When Heart and Kidney interact, Spirit nourishes each other. That which accompanies Shen and moves with it is called Hun (Ethereal Soul). That which exits and enters with Jing is called Po (Corporeal Soul). When Spirit is mutually nourished, Hun and Po naturally calm. Sweet flavor benefits the Spleen. The Spleen is the Post-Heaven foundation. Qi originates from Pre-Heaven Heaven and is filled by grain. Post-Heaven digestion of grain thus benefits Qi. Heart disorders often involve the Liver. If Heart Fire does not flare upward, Liver Blood is offered upwards, thereby brightening the eyes. The red color possesses the Yangming hue of the South. Yangming can repel Yin darkness, thus expelling demons and evil spirits. The reason long-term consumption promotes spiritual clarity and longevity is that the Heart stores Shen Ming (Spiritual Clarity). Long-term consumption of Dansha clears Heart Fire. When Fire is clear, Blood is abundant, resulting in a vacant, spiritual, and unobscured mind, and a radiant complexion.
