疏通经络，祛除风寒。
治疗心腹冷痛，风寒湿痹，附骨阴疽。凡是筋骨间隐痛的症状，用火针针刺。火气能直达疼痛部位，效果显著。（李时珍说：神针火的制作方法，是取农历五月初五当天生长的向东延伸的桃树枝，削成如鸡蛋大小、长五六寸的木针，晾干备用。使用时用三到五层绵纸垫在患处，将木针蘸取麻油点燃，吹灭明火，趁热迅速刺入患处。）
雷火神针。（配方为：陈年艾叶末二两，乳香、没药、穿山甲、硫黄、草乌头、川乌头、桃树皮末各一钱，麝香五分。将这些药材研成细末与艾叶混合，用厚纸裁成长条，将药艾铺在内层，紧紧卷成手指粗细、长三四寸的艾条，装入瓶中密封，埋入地下七天。取出后，在灯上点燃一端，吹灭明火，隔十层纸，趁热针刺患处，热气直透体内，疗效更快，同时忌食冷水。）
疏通经络，祛风。
治疗风寒引起的筋脉拘急，抽搐牵引导致的痹痛，或中风瘫痪肢体麻木不仁者。针刺后快速出针，立即按压针孔则疼痛停止；若不按压则疼痛加剧。对于症瘕积聚等寒凝病症，针刺后缓慢出针，并转动针体以排出污浊之气。对于痈疽发背，有脓但无疮头者，针刺使脓液溃破，不要按压针孔。
凡使用火针，刺得太深会损伤经络，太浅则不能去除病邪，关键在于掌握深浅适度。针刺后出现发热恶寒，这是中病的表现（即药力/针力作用于病灶）。凡是面部以及夏季，湿热之邪在下肢时，都不可使用此法。（李时珍说：《素问》记载：病在筋，调理筋，用燔针劫刺其下方，及筋脉拘急者；病在骨，调理骨，用淬针配合药物熨烫。另外《灵枢经》叙述十二经筋所发的各种痹痛，都说治疗在于燔针劫刺，以病情好转为度，以痛点为腧穴。又说：经筋的病，受寒则反折筋脉拘急，受热则松弛不收，阳痿不用。淬刺适用于寒性筋急，而松弛不收者，不宜用燔针。由此可见，燔针是为筋寒而拘急者设立的，以热治寒，是正治之法。而后世用火针治疗积块，也是借火气来散寒湿，排出污浊。或者又用它治疗痈疽，则是采用从治之法，溃泄毒瓦斯。而那些不明事理的人用它治疗伤寒热病，就错了。张仲景说：太阳伤寒证加用温针，必定引发惊悸；营气微弱者，加用烧针则血液运行不畅，更加发热而烦躁。太阳病误用下法，导致心下痞满，表里俱虚，阴阳俱竭，若再误用烧针，会出现胸烦，面色青黄，皮肤润泽者难治。这些都是用针者不了解古代哲人设立针法的原理，而错误使用导致害人的案例。另外，凡是肝血虚导致目昏多泪，或风热赤眼及生翳膜，顽固浓稠成病，后来生出白膜失明，或五脏虚劳，风热上冲于目生翳，病症适宜用熨烙疗法。因为气血得温则宣通流畅，得寒则凝涩。具体方法是使用平头针，大小如孔，烧红后轻轻在翳膜中央烙之。烙后翳膜破裂，随即用除翳药物敷点。）
火针。《素问》称之为燔针、淬针。张仲景称之为烧针。川蜀地区人称之为煨针。（其制作方法：用一盏麻油，点燃七根灯草作为灯芯，将针频繁涂抹麻油，在灯上烧至通红使用。如果不红或冷，则不能去病，反而损害人体。这种针最好用火箸铁制造，点穴时用墨记号标记，位置偏差则无效。）
Unblock meridians, dispel wind and cold.
Treats cold pain in the heart and abdomen, bi-syndrome caused by wind-cold-dampness, and Yin abscesses adhering to bones (Fugu Yinju). For any hidden pain in the muscles and bones, needle with fire needles. The fire energy reaches directly to the site of pain, yielding very effective results. (Li Shizhen said: To make the Divine Needle Fire, take peach branches growing eastward on the fifth day of the fifth lunar month, carve them into wooden needles the size of a chicken egg, five or six cun long, and dry them. When using, place three to five layers of cotton paper on the affected area, dip the needle in sesame oil, ignite it, extinguish the flame, and prick the area while hot.)
Thunder-Fire Divine Needle. (Formula: Two liang of aged mugwort leaf powder; one qian each of frankincense (Ruxiang), myrrh (Moyao), pangolin scales (Chuanshanjia), sulfur (Liuhuang), aconite root lateralis preparata (Caowutou), aconitum carmichaelii deoxyaconitine root preparata (Chuanwutou), and peach tree bark powder; five fen of musk (Shexiang). Grind these herbs into fine powder and mix with mugwort. Roll tightly into strips the thickness of a finger and three to four cun long using thick paper, store in a bottle, and bury underground for seven days. Take out, light one end over a lamp, extinguish the flame, place ten layers of paper between the needle and the skin, and prick the affected area while hot. The heat penetrates directly, making the effect even faster. Cold water is contraindicated during use.)
Unblock meridians, dispel wind.
Treats tendon stiffness caused by wind-cold, spasmodic牵引 leading to bi-pain, or paralysis with numbness. Withdraw the needle quickly after insertion; immediately press the acupoint hole to stop pain; if not pressed, pain worsens. For conditions involving masses, accumulations, and cold diseases, withdraw the needle slowly and rotate it to discharge turbid pathogenic factors. For back carbuncles (Yongju Fabei) where pus exists but has no head, needle to allow pus to drain; do not press the hole.
When using fire needles, inserting too deeply damages meridians and collaterals, while inserting too shallowly fails to eliminate disease. The key lies in judging the depth appropriately. Fever and aversion to cold after needling indicate that the treatment has struck the disease (Zhongbing). This method is contraindicated on the face, during summer months, and when damp-heat affects the lower limbs. (Li Shizhen said: The *Suwen* states: If the disease is in the tendons, regulate the tendons by burning needles and seizing the acupuncture points below, and for those with tendon stiffness... If the disease is in the bones, regulate the bones by quenching needles and applying medicinal moxibustion/warming. Furthermore, the *Lingshu Jing* describes various bi-pains arising from the twelve tendon meridians, stating that treatment involves burning needles and seizing acupuncture points, taking improvement as the limit, and using the painful point as the shu point. It also states: Diseases of the tendon meridians, when cold, cause reverse bending and tendon stiffness; when hot, they cause flaccidity and inability to contract, or impotence and inability to use. Quenching/acupuncture is for cold-induced stiffness; flaccidity should not be treated with burning needles. Thus, burning needles are designed for cold-induced tendon stiffness, using heat to treat cold, which is the correct method. Later generations used fire needles for masses, borrowing fire energy to dispel cold-dampness and discharge turbidity. Or used for carbuncles, employing the contrary method to drain toxins. However, ignorant people using it for cold damage and febrile diseases is incorrect. Zhang Zhongjing said: In Taiyang cold damage, adding warm needles will surely cause palpitations/fright; in those with weak Ying Qi, adding burning needles causes blood flow stagnation, worsening fever and irritability. After purgative therapy for Taiyang disease leads to epigastric fullness, with both exterior and interior deficient, and Yin and Yang exhausted, adding burning needles again causes chest vexation, bluish-yellow complexion, and moist skin—these are difficult to treat. These are all cases where practitioners, not understanding the principles set by ancient sages, misuse needles causing harm. Additionally, for liver deficiency causing dim vision and excessive tearing, or wind-red eyes and pterygium formation, stubborn purulent disease, subsequent white membrane blindness, or five viscera deficiency labor with wind-heat rushing upward to the eyes causing pterygium, warming and cauterizing methods are suitable. This is because Qi and Blood flow freely when warm and stagnate when cold. The method uses a flat-headed needle, sized like a pore, heated red, and gently cauterized at the center of the pterygium. After cauterization breaks the membrane, apply depurating eye medicine.)
Fire Needle. Known as Burning Needle (Fan Zhen) or Quenching Needle (Cui Zhen) in the *Suwen*; Burning Needle (Shao Zhen) by Zhang Zhongjing; Warming Needle (Wei Zhen) in Sichuan/Shu regions. (Method: Fill a cup with sesame oil, light seven reed grass wicks. Frequently coat the needle with sesame oil and burn it over the lamp until thoroughly red before use. If not red or cold, it cannot cure disease and may harm the person. Needles made of iron from fire tongs are best. Mark acupoints with ink; deviation renders it ineffective.)
