本经逢原云∶北方炊食多用煤火，以地属坎，足胜其气，且助命门真火。食煤火长气于
阴，
所以膂力强壮，南人食之多发痈毒。受其毒者，以 汁解之。然煤火处置大缸水于旁，则毒
从水解。南方炊食多用薪火，人食薪火，长气于阳。气多轻浮不实，不似北方之禀气刚劲也
。然近日南方亦产煤，薪价日昂，市井多有用煤者，其煤在浙省则出于衢严，湖州较北，煤
坚细，以之代薪。瓦斯亦减薄，甚有如薪炭无臭气者，名曰香煤。出太湖山中，纲目石部收
乌金石，即煤也。其主治多言其质之用，而火部又不收煤火，故为补之。用以香煤为佳。
烹一切食物，能和脾胃。滋气力、通肾气、助阳道。妇人暖子宫。杂煤臭煤有毒。
能够驱散鬼磷和野外邪祟，用戛金（一种取火工具）取火照射它，邪祟就会消失踪迹。
就是人的元气，能够救治突然死亡或梦魇而死的人，用口对着患者吹气调理气息就能苏醒，能驱散鬼气，呵气吹拂它就能消散。治疗痘疮，凡是阴寒导致痘疹不起发、不灌浆的，用身体强壮之人的口气呵在患处，痘疹就会起发变得红润鲜活，浆液运行而毒素化解。停止腹痛腹泻，老年人多有因气弱受寒而患此病的，用壮年人将手搓得极热，频繁互相覆盖在患者的肚脐上，使手中的热气透入丹田即可自愈。这是借助君火（心火/阳气）的力量。
龙从石中兴起，石头内部一定有焦裂的地方，那是龙口喷出的火烧灼所致，刮下石末煎汤服用，治疗痞膈（胸腹间结块胀满不适）效果神奇，因为石头承受了龙火的……（原文此处似有缺漏，依文意补全逻辑：其性受热石之效）。
雷击的树木木材中有硫黄气味，是因为得到了雷火之气。能治疗惊痫和邪祟，配合辟瘟丹使用效果极佳。
（煤火/毒气）有毒，不宜接触物体。用纸捻蘸油点燃灯火照在疮口上，可以引出毒素排出体外。
（煤烟/毒气）附着在身上能腐蚀肌肉腐烂，可以用来按摩治疗风气病。
普通人都不能运用它，只有修道之士才能运用它来治病，让人起死回生。相火（命门之火）能凝结成舍利，形成坚固的子实体，三种火能杀死精魅。
用金属器具烧红后烙在肉上，能止血。凡是人神所在之处，误针导致出血不止的，烧红金属器具烙烫它（选自《选元方》）。
《本经逢原》说：北方做饭多用煤火，因为地势属坎（水），足以胜其寒气，并且能助长命门的真火。食用煤火煮的食物，能使阴气增长，所以体力强壮；南方人吃这种食物容易引发痈毒。受到毒气侵害的，用某种汁液解毒。然而如果在煤火旁放置大缸盛水，则毒性随水解去。南方做饭多用柴火，人食用柴火煮的食物，使阳气增长。阳气多轻浮不实，不像北方禀受的刚劲之气。然而近日南方也产煤，柴价日益昂贵，市井中很多人开始用煤。浙江地区的煤产自衢州、严州，湖州的煤比北方的更坚硬细致，用它代替柴薪。瓦斯也减少变薄，甚至有像薪炭一样没有臭气的，名叫“香煤”。出产于太湖山中，《本草纲目》石部收录了乌金石，就是煤。关于煤的主治大多讲的是其材质的用途，而火部又不收录煤火，所以在此补充。使用香煤为佳。烹煮各种食物，能调和脾胃。滋养气力、通利肾气、助益阳道。妇女用来温暖子宫。混杂的煤和臭煤是有毒的。
It can disperse ghostly phosphorus and wild malevolent influences; illuminating it with fire obtained from striking metal (Gajin) will cause the traces to vanish.
Human vital energy (Yuan Qi) can rescue those who have died suddenly or from nightmare death (Yan Si); breathing air into their mouths to regulate their breath brings them back to life, disperses ghostly qi, and blowing upon them causes the evil to dissipate. To induce the eruption of smallpox/variolous pustules, in cases where yin-cold prevents the lesions from rising or filling with pus, one should use the breath of a robust person to blow upon the affected area; this causes the lesions to rise, become red and vibrant, allows the pus to flow, and resolves the toxin. To stop abdominal pain and diarrhea—conditions common in the elderly due to weak qi and cold invasion—one should have a strong adult rub their hands until extremely hot and frequently cover the patient's navel, allowing the heat from the hands to penetrate the Dantian for self-healing. This utilizes the power of Jun Huo (Monarch Fire/Heart Yang).
Dragons rise from stones; within these stones, there must be scorched and cracked areas, burned by the fire from the dragon's mouth. Scraping the stone powder and decocting it in water treats Pi Ge (obstruction/fullness in the chest and abdomen) with miraculous effect, as the stone has absorbed the dragon's fire... [Text fragment missing].
Wood struck by lightning contains the scent of sulfur, having received the qi of thunder-fire. It can treat Jing Xian (convulsions and epilepsy) and malevolent influences; when combined with Biwen Dan (Plague-Dispelling Pill), it is most effective.
[Coal smoke/toxicity] is toxic and unsuitable for contact with objects. Dipping a paper wick in oil and lighting it to shine upon sores can draw toxins out.
[Coal smoke/toxicity] adhering to the body can corrode flesh and cause rot; it can be used for massage to treat wind-pathogen diseases.
Ordinary people cannot utilize it; only Daoist practitioners can employ it to treat illnesses, bringing the dead back to life. Xiang Huo (Ministerial Fire) can condense sarira (relics) and form solid seeds; the three types of fire can kill spirits and demons.
Heating a metal vessel until red-hot and cauterizing the flesh stops bleeding. If accidental needling at the location of the Shen (Spirit) causes unceasing bleeding, cauterize it with a heated metal vessel (Selected from *Xuan Yuan Fang*).
*Benjing Fengyuan* states: In the North, cooking mostly uses coal fire. Since the region belongs to Kan (Water), it sufficiently overcomes the cold qi and assists the True Fire of the Mingmen (Gate of Life). Consuming food cooked with coal fire nourishes Yin, resulting in strong physical strength; however, Southerners consuming such food often develop carbuncles and sores. Those poisoned by it are treated with specific juices to detoxify. However, placing large vats of water near the coal fire allows the toxicity to be dissolved by the water. In the South, cooking mostly uses wood/fire. Consuming food cooked with wood fire nourishes Yang. The qi generated is light and floating, lacking the robust quality of Northern qi. Recently, coal is also produced in the South, and as wood prices rise, many market people use coal. Coal from Zhejiang originates from Quzhou and Yanzhou; coal from Huzhou is harder and finer than northern coal and serves well as a substitute for firewood. Its gas emissions are thinner, and some varieties, like charcoal, have no odor, named "Fragrant Coal" (Xiang Mei). It comes from the mountains around Taihu Lake. *Bencao Gangmu* lists Wujinshi (Black Gold Stone) in the Mineral section, which is coal. Most treatments mentioned refer to the material use of coal, while the Fire section does not record coal fire, hence this supplement. Using Fragrant Coal is best. Cooking all foods with it harmonizes the Spleen and Stomach, nourishes vitality, unblocks Kidney qi, and aids Yang function. For women, it warms the uterus. Mixed coal and smelly coal are toxic.
