白炭火主治误吞金银铜铁等异物卡在腹中，将其烧红后迅速研成细末，煎汤服用；病情严重者，刮取炭末三钱，用井水调服，若未见效可再次服用。（出自《本草纲目》）
【产地】将木材烧制成炭，各地都有。各种木材都可以烧炭入药，但药用只使用白炭和栎炭。
【用法】白炭质地坚硬，木材久置则会腐烂，而烧成的炭埋入土中却不腐烂，这是因为木材具有“生性”，而炭没有“生性”。殡葬家用炭能使虫蚁不侵入竹木的根部，也是因为它没有生性。古代在冬至、夏至前两天，将土和炭悬挂在秤的两端使其平衡，阴气至则土重，阳气至则炭重。
【质地】长短不等，大小不齐。
【颜色】生炭呈红色，死炭呈黑色。
【性味】温热。
【治疗功效】（出自《百一方》）治疗白癞头疮，将白炭烧红投入沸水中，用温水清洗患处，可获疗效。○（出自《千金方》）治疗突然发生的咽喉噎塞，用炭末加蜜制成丸剂含咽。○（出自《济急方》）治疗汤火灼伤，用炭末调和香油涂抹。
【配合治疗】（出自《圣惠方》）治疗白虎痛风，疼痛日夜游走于全身关节，如被啃咬一般，用炭灰五升、蚯蚓泥一升、红花七捻混合熬制，用醋拌和，用旧布包裹做成两个药包，交替熨烫疼痛部位，可获疗效。
【解毒功效】（李时珍说）解除水银、轻粉的毒性，将带火的炭放入水中，能吸取出水银。站立放置炭火可以辟除邪恶鬼气，除夕夜立在门内也能辟除邪恶祟气。栎木炭火主要用于炼制各种金石药物。（出自《品汇分录》）○（出自周王普济方）治疗新旧肠风下血，用紧炭三钱、枳壳烧至存性五钱，研为细末，每次服用三钱，五更天用米饮送服，天明再服一次，当天见效。忌食油腻及有毒食物。
炭火主要用于烹煮、煎熬、焙烤炙制各种药物丸散。（出自《品汇分录》）○（出自陈氏经验方）治疗阴囊湿痹，用麸皮炭和紫苏叶末扑撒患处。
Bai Tan Huo (White Charcoal Fire) is indicated for the accidental ingestion of gold, silver, copper, or iron lodged in the abdomen. The charcoal should be heated until red-hot, rapidly ground into a fine powder, decocted in water, and taken orally. For severe cases, scrape off three qian of charcoal powder, mix with well water, and administer; if ineffective, repeat the dose. (From *Bencao Gangmu*)
[Origin] Wood burned into charcoal is available everywhere. Various types of wood can be carbonized for medicinal use, but only Bai Tan (White Charcoal) and Li Tan (Oak Charcoal) are used medicinally.
[Usage] Bai Tan (White Charcoal) is hard and solid. Wood decays over time, but charcoal buried in soil does not decay because wood possesses "Sheng Xing" (Vital Nature), whereas charcoal lacks it. Funeral practitioners use charcoal to prevent insects and ants from penetrating bamboo and wood roots, precisely because it lacks this vital nature. In ancient times, two days before the Winter Solstice and Summer Solstice, earth and charcoal were hung on opposite ends of a balance scale to achieve equilibrium. When Yin Qi arrives, the earth becomes heavier; when Yang Qi arrives, the charcoal becomes heavier.
[Texture] Unequal in length and size.
[Color] Raw charcoal appears red; dead charcoal appears black.
[Nature] Warm and hot.
[Qi Movement] The flame can ascend and descend; it is Yang within Yin, and also Yin within Yang.
[Therapeutic Actions] (From *Baiyi Fang*): Treats Bai Lai Tou Chuang (White Leukoderma of the scalp). Heat white charcoal until red-hot, immerse it in boiling water, and wash the affected area with the warm solution for efficacy. ○ (From *Qianjin Fang*): Treats sudden pharyngeal obstruction. Mix charcoal powder with honey to form pills, which are held in the mouth and swallowed. ○ (From *Jiji Fang*): Treats scalds and burns. Mix charcoal powder with sesame oil and apply topically.
[Combined Therapy] (From *Shenghui Fang*): Treats Bai Hu Feng Tong (White Tiger Gout), characterized by pain wandering day and night through all joints as if being bitten. Use five sheng of charcoal ash, one sheng of earthworm mud, and seven niann of Hong Hua (Carthamus tinctorius flowers). Mix and simmer, then combine with vinegar. Wrap in old cloth to make two packs, and alternately apply hot compresses to the painful areas for efficacy.
[Detoxification] (Li Shizhen stated): Resolves toxicity from Mercury (Shuiyin) and Calomel (Qingfen). Placing fire-laden charcoal into water extracts mercury from it. Standing charcoal wards off evil spirits and malevolent Qi; placing it indoors on New Year's Eve wards off evil influences. Oak charcoal fire is primarily used for refining metallic and mineral medicines. (From *Pinhui Fenlu*) ○ (From Zhou Wang Puji Fang): Treats chronic or acute Chang Feng Xia Xue (Intestinal Wind with lower bleeding). Use three qian of dense charcoal and five qian of Zhi Qiao (Aurantii Fructus) roasted until charred but retaining its nature. Grind into powder. Take three qian per dose at dawn with rice water, and another dose at sunrise. Efficacy is seen on the same day. Avoid greasy and toxic foods.
Tan Huo (Charcoal Fire) is mainly used for cooking, decocting, roasting, and baking various herbal pills and powders. (From *Pinhui Fenlu*) ○ (From Chen Shi Jingyan Fang): Treats Yin Nang Shi Bi (Damp Bi Syndrome of the Scrotum). Dust the area with Fu Pi Tan (Rice Husk Charcoal) and Zi Su Ye Mo (Perilla Leaf Powder).
