火类 土类
主治痈疽发背不起。瘀肉不腐。及阴疮瘰 。流注 疮顽疮。然火吹灭。（日炙二次。）
未溃
拔毒止痛。已溃补接阳气。去腐生肌。凡一切补药诸膏。宜此火煎之。但不可点艾伤肌。（
震亨曰∶火以畅达、拔引郁毒、此从治之法也、时珍曰∶桑木能利关节、养津液、得火则拔
引毒瓦斯、而祛逐风寒、所以能去腐生新也、抱朴子云∶一切仙药、不得桑煎不服、桑乃箕星
之精、能助药力、除风寒痹诸痛、久服、终身不患风疾故也。）
栎炭火、宜 炼一切金石药。 炭火、宜烹煎炙焙百药丸散。（时珍曰∶烧木为炭、木
久则
腐、而炭入土不腐者、木有生性、炭无生性也、葬家用炭、能使虫蚁不入、竹木之根自回、
亦缘其无生性尔。）
宜煎一切滋补药。（时珍曰∶凡服汤药、虽品物专精、修治如法、而煎药者卤莽造次、
水火
不良、火候失度、药亦无功。观夫茶味之美恶、饭味之甘 、皆系于水火烹饪之得失、故煎
药须用小心老成人、以深罐密封、新水活火、先武后文、如法服之、未有不效者、火用陈芦
枯竹、取其不强、不损药力也、桑柴火取其能助药力、 炭取其力慢、栎炭取其力紧、温养
用糠及马屎牛屎者、取其暖、而能使药力匀遍也。）
治小儿惊风，昏迷搐搦窜视诸病。又治头风胀痛。视头额太阳络脉盛处。以灯心蘸麻油。
点
灯淬之。良。外痔肿痛者。亦淬之。油能去风解毒。火能通经也。小儿初生。因冒寒气欲绝
者。勿断脐。急烘絮包之。将胎衣烘热。用灯炷于脐下。往来燎之。暖气入腹内。气回自苏。
去风退赤甚妙。（时珍曰∶凡灯惟胡麻油苏子油然者、能明目治
病、其余诸油灯烟、皆能损目、亦不治病也。）
火类、土类（指以火为用或属土的药材/疗法）
主治痈疽发背（背部严重的化脓性感染）疮疡平塌不起，瘀死肌肉不腐烂，以及阴疮、瘰疬（颈部淋巴结结核）、流注（多发性深部脓肿）、顽疮。使用时需将火吹灭。（需经日晒两次。）
疮疡未溃破时：
具有拔毒止痛的功效。
疮疡已溃破后：
具有补接阳气、去除腐肉、促进新肌生长的功效。凡是所有的补益类药物及膏剂，适宜用此火煎煮。但不可使用艾火直接灼伤肌肤。（朱震亨说：火能疏通畅达，拔引郁结之毒，这是“从治”的治疗方法。李时珍说：桑木能利关节、养津液，得火则能拔引毒气，祛除风寒，所以能去腐生新。抱朴子说：一切仙药，不用桑木煎煮则不服用，桑树是箕星精气所化，能助药力，除风寒痹痛诸症，久服可终身不患风疾。）
栎炭火：适宜炼制各种金石药物。
炭火：适宜烹煎、炙焙各种丸散药物。（李时珍说：烧木成炭，木头久放会腐烂，而炭埋入土中不腐烂，是因为木头有生性，炭没有生性。葬家用炭，能使虫蚁不入，竹木根系自然回生，也是因为没有生性的缘故。）
适宜煎煮各种滋补药物。（李时珍说：凡服用汤药，虽然药材品种专精，炮制方法正确，但如果煎药者粗鲁草率，水火不调，火候失度，药物也无效。看茶味的美恶、饭味的甘苦，都取决于水火烹饪的得失，所以煎药需用小心谨慎的老成人，用深罐密封，用新水活火，先武火后文火，依法服用，没有无效的。用火方面，陈芦枯竹取其火力不强，不损药力；桑柴火取其能助药力；炭火取其火力缓慢；栎炭火取其火力紧实；温养药用谷糠及马屎牛屎，取其温暖，且能使药力均匀遍布。）
治疗小儿惊风，昏迷抽搐、眼球上窜等各种病症。又治疗头风胀痛。观察头部、额头、太阳穴络脉充盈处，用灯心草蘸麻油，点灯淬烫患处，效果良好。外痔肿痛者，也可用此法淬烫。油能祛风解毒，火能通经。小儿初生，因受寒气欲绝者，不要剪断脐带，急忙用烘热的棉絮包裹，将胎衣烘热，用灯芯在脐下往来燎烤，暖气进入腹内，气回自醒。祛风退赤效果极佳。（李时珍说：凡是用胡麻油、苏子油点燃的灯，能明目治病，其余各种油灯的烟，都能损伤眼睛，也不治病。）
Fire Category, Earth Category (Refers to medicinal materials or therapies utilizing fire or belonging to the Earth element)
Indications: Carbuncles and back sores (severe purulent infections of the back) that are flat and do not rise; necrotic flesh that does not rot; as well as yin sores, scrofula (tuberculous lymphadenitis of the neck), liuzhu (multiple deep-seated abscesses), and stubborn ulcers. Usage: Extinguish the flame. (Sun-dry twice.)
Before ulceration:
Has the effect of drawing out toxins and relieving pain.
After ulceration:
Has the effects of supplementing and connecting Yang Qi, removing necrotic tissue, and generating new muscle. All tonifying medicines and ointments should be decocted using this type of fire. However, moxa direct moxibustion should be avoided to prevent damaging the skin. (Zhu Zhenheng stated: Fire can facilitate unblocking and draining, drawing out stagnant toxins; this is a method of "treating in accordance with" (Congzhi). Li Shizhen stated: Mulberry wood can benefit joints and nourish body fluids. When ignited, it draws out toxic vapors and expels wind-cold, thereby enabling the removal of necrotic tissue and generation of new tissue. Baopuzi stated: All immortal medicines are ineffective unless decocted with mulberry wood. The mulberry tree is the essence of the Ji Star, capable of assisting medicinal potency, eliminating wind-cold bi-syndrome and various pains. Long-term use prevents wind diseases for life.)
Oak charcoal fire: Suitable for refining various mineral and metallic drugs.
Charcoal fire: Suitable for decocting, roasting, and baking various pills and powders. (Li Shizhen stated: Burning wood into charcoal; wood rots over time, but charcoal buried in soil does not rot because wood possesses a "living nature," whereas charcoal lacks it. Funeral practitioners use charcoal to prevent insects and ants from entering, allowing bamboo and wood roots to regenerate naturally, also due to its lack of living nature.)
Suitable for decocting all kinds of tonifying medicines. (Li Shizhen stated: Regarding the administration of herbal decoctions, even if the ingredients are of superior quality and processed correctly, if the person decocting is careless, the water and fire are improper, or the heat control is inaccurate, the medicine will be ineffective. Observe how the quality of tea flavor and the taste of rice depend on the success or failure of water and fire cooking. Therefore, decocting requires careful and experienced individuals, using deep pots sealed tightly, fresh water, and active fire. Start with strong fire (Wu Huo) then switch to mild fire (Wen Huo). Administer according to method, and there will be no ineffectiveness. For fuel, dried reeds and dead bamboo are chosen for their mild heat, which does not damage medicinal potency. Mulberry wood fire is chosen for its ability to assist medicinal potency. Charcoal fire is chosen for its slow heat. Oak charcoal fire is chosen for its intense heat. For warming and nourishing, bran, horse manure, and cow manure are used for their warmth, ensuring the medicinal potency spreads evenly.)
Treats pediatric convulsive disease (Jing Feng), including coma, spasms, and upward deviation of eyes. Also treats head wind causing distending pain. Observe the areas where collaterals on the head, forehead, and temples are prominent. Dip rush pith (Jiedixin) in sesame oil, light it, and cauterize the affected area. This is effective. External hemorrhoids with swelling and pain can also be treated by cauterization. Oil dispels wind and resolves toxicity; fire unblocks meridians. For newborns who are near death due to exposure to cold qi, do not cut the umbilical cord immediately. Quickly wrap them in heated cotton wadding. Heat the placenta, place the lamp wick below the navel, and roast it back and forth. The warm qi enters the abdomen, Qi returns, and consciousness recovers spontaneously. Dispelling wind and reducing redness is very effective. (Li Shizhen stated: Only lamps lit with sesame oil and perilla seed oil can brighten the eyes and treat diseases. The smoke from other types of oil lamps damages the eyes and does not treat diseases.)
