雷公真君曰∶凡人有腹痛不能忍，按之愈痛，口渴饮冷水则痛止，少顷依然大痛，此火结在
大小肠，若不急治，亦一时气绝。方用定痛至神汤∶炒栀子三钱，甘草一钱，茯苓一两、白芍五钱，苍
术三钱，大黄一钱，浓朴一钱，水煎服。此方妙在舒肝经之气，用白芍、甘草和其痛，尤妙多用茯苓
为君，以利膀胱之水，更妙在栀子以泻郁热之气，又恐行之欠速，更佐之大黄，走而不守，则泻火逐
瘀，尤为至神也。
雷公真君曰∶凡人有咽喉忽肿作痛，生双蛾者，饮食不能下，五日不食即死矣。但此症实火易
治，而虚火难医，实火世人已有妙方，如用山豆根，芩、连、半夏、柴胡、甘草、桔梗、天花粉治之
立消。惟虚火乃肾火不藏于命门，浮游于咽喉之间，其症亦如实火，惟夜重于日，清晨反觉少轻；若
实火清晨反重，夜间反轻。实火，口燥舌干而开裂；虚火，口不甚渴，舌滑而不裂也。以此辨症，断
不差错。此种虚痛，若亦以治实火之法治之。是人已下井，而又益之石也。故不特不可用寒凉，并
不可用发散。盖虚火必须补也，然徒补肾水，虽水能制火。可以少差，而火势太盛，未易制伏，又宜
于水中补火，则引火归源而火势顿除，有消亡于顷刻矣。方用引火汤，熟地一两；元参一两。白芥子
三钱，山茱萸四钱，北五味二钱，山药四钱，茯苓五钱，肉桂二钱，水煎服。一剂而痰声静，痛顿
除、肿亦尽消，二剂全愈。盖熟地、山茱萸、五味之类，纯是补肾水圣药，茯苓、山药又益精而利水，
助肉桂之下行，元参以消在上之浮火，白芥子以消壅塞之痰，上焦既宽，而下焦又得肉桂之热，则龙雷
之火有不归根于命门者乎。一剂便生，真有鬼神莫测之机，又胜于八味地黄汤也。倘喉肿闭塞，勺水
不能下，虽有此神方，将安施乎。我更有法，用附子一个，破故纸五钱。各研末，调如糊作膏，布摊如
膏药，大如茶钟。贴脚心中央，以火烘之一时辰，喉即宽而开一线路，可以服药矣，又不可不知此妙
法也。
雷公真君说：大凡有人腹痛难以忍受，按压时疼痛加剧，口渴喝冷水后疼痛暂时停止，但过了一会儿依然剧烈疼痛，这是火邪结聚在大小肠所致，如果不紧急治疗，也会导致一时气绝。方剂用定痛至神汤：炒栀子三钱，甘草一钱，茯苓一两，白芍五钱，苍术三钱，大黄一钱，厚朴一钱，水煎服。这个方子的妙处在于疏舒肝经之气，用白芍、甘草来调和缓解疼痛；尤其妙在重用茯苓为君药，以通利膀胱之水；更妙在用栀子来泻除郁积的热气；又担心药力运行不够迅速，所以再佐以大黄，大黄走而不守，从而泻火逐瘀，尤为神奇。
雷公真君说：大凡有人咽喉突然肿胀作痛，长出双蛾（扁桃体肿大），饮食无法吞咽，如果五天不进食就会死亡。但是这种病症中，实火容易治疗，而虚火难医。实火世人已有妙方，如使用山豆根、黄芩、黄连、半夏、柴胡、甘草、桔梗、天花粉来治疗，立刻就能消除。只有虚火是肾火不能藏于命门，浮游于咽喉之间，其症状也像实火一样，只是夜间比白天重，清晨反而觉得稍轻；若是实火，则清晨反而重，夜间反而轻。实火表现为口燥舌干且开裂；虚火表现为口不太渴，舌面滑润且不裂。以此辨别症状，绝不会出错。这种虚火引起的疼痛，如果也用治疗实火的方法来治疗，那就是把人已经推下井，又往里面加石头。所以不仅不能用寒凉药，也不可用发散药。因为虚火必须用补法，然而单纯补肾水，虽然水能制火，可以稍微好转，但火势太盛，不容易制服，又适宜在水中补火，这样就能引火归源，火势顿时消除，顷刻间就消亡了。方剂用引火汤：熟地黄一两，玄参一两，白芥子三钱，山茱萸四钱，北五味子二钱，山药四钱，茯苓五钱，肉桂二钱，水煎服。服用一剂后痰声平息，疼痛顿除，肿胀也完全消退，两剂后痊愈。大概熟地、山茱萸、五味子这类药物，纯粹是补肾水的圣药，茯苓、山药又能益精并利水，辅助肉桂下行，玄参用来消除在上部的浮火，白芥子用来消除壅塞的痰浊，上焦既然宽畅，而下焦又得到肉桂的热力，那么龙雷之火有不回归到命门的吗？一剂见效，真有鬼神莫测的机理，又胜过八味地黄汤。倘若喉肿闭塞严重，连一勺水都喝不下，虽然有此神方，又能施展在哪里呢？我还有更好的方法，用一个附子，五钱破故纸（补骨脂）。分别研成粉末，调成糊状做成膏药，布摊开像膏药那么大，如茶杯盖大小。贴在脚心中央，用火烘烤一个时辰，喉咙就会宽松并开辟出一条通路，就可以服药了，这妙法也不可不知道。
Lei Gong Zhen Jun said: Generally, when a person suffers from unbearable abdominal pain that worsens upon pressure, and thirst quenched by drinking cold water temporarily relieves the pain but severe pain returns shortly after, this indicates Fire pathogen binding in the Large Intestine (Da Chang) and Small Intestine (Xiao Chang). If not treated urgently, it may lead to sudden Qi collapse. The prescription is Ding Tong Zhi Shen Tang (Stabilize Pain Extremely Divine Decoction): Stir-fried Gardenia Fructus (Chao Zhizi) 3 qian, Licorice Root (Gancao) 1 qian, Poria Sclerotium (Fuling) 1 liang, White Peony Root (Baishao) 5 qian, Atractylodes Rhizome (Cangzhu) 3 qian, Rhubarb Radix et Rhizoma (Dahuang) 1 qian, Magnolia Bark (Houpo) 1 qian. Decoct in water and take orally. The brilliance of this formula lies in soothing the Qi of the Liver Meridian (Gan Jing); using Baishao and Gancao to harmonize and relieve pain; particularly brilliant is using Fuling as the sovereign herb to promote diuresis via the Bladder (Pang Guang); even more brilliant is using Zhizi to drain stagnant Heat; fearing the action might be too slow, Dahuang is added as an assistant, which moves without staying, thereby draining Fire and expelling Blood stasis (Yu Yu), making it extremely divine.
Lei Gong Zhen Jun said: Generally, when a person’s throat suddenly swells and hurts, developing double tonsillar hypertrophy (Shuang E), making swallowing impossible, death will occur if no food is taken for five days. However, among these conditions, Excess Fire (Shi Huo) is easy to treat, while Deficient Fire (Xu Huo) is difficult. For Excess Fire, there are already excellent prescriptions, such as using Manchu Walnut Tree Root Bark (Shandougen), Scutellaria Root (Qin), Coptis Rhizome (Lian), Pinellia Tuber (Banxia), Bupleurum Root (Chaihu), Licorice Root (Gancao), Platycodon Root (Jiegeng), and Trichosanthes Root (Tianhuafen), which can eliminate symptoms immediately. Only Deficient Fire occurs when Kidney Fire (Shen Huo) fails to reside in the Gate of Vitality (Ming Men) and floats between the throat and pharynx. Its symptoms resemble Excess Fire, but are worse at night and lighter in the early morning; conversely, Excess Fire is heavier in the morning and lighter at night. Excess Fire presents with dry mouth, dry tongue, and cracking; Deficient Fire presents with little thirst, a slippery tongue surface, and no cracking. By distinguishing symptoms thus, errors are avoided. If this Deficient Fire pain is treated with methods for Excess Fire, it is like pushing someone into a well and adding stones. Therefore, one must not use Cold/Cool herbs, nor dispersing herbs. Since Deficient Fire requires tonification, merely tonifying Kidney Water (Shen Shui) allows Water to control Fire, offering slight improvement, but if Fire is too strong, it is hard to subdue. It is better to tonify Fire within Water, guiding Fire back to its source (Yin Huo Gui Yuan), causing the Fire to vanish instantly. The prescription is Yin Huo Tang (Guide Fire Back to Source Decoction): Prepared Rehmannia Root (Shudi) 1 liang, Scrophularia Root (Yuanshen) 1 liang, White Mustard Seed (Baijiezi) 3 qian, Cornus Fruit (Shanzhuyu) 4 qian, Schisandra Berry (Beiwuweizi) 2 qian, Chinese Yam (Shanyao) 4 qian, Poria Sclerotium (Fuling) 5 qian, Cinnamon Twig (Rougui) 2 qian. Decoct in water and take orally. After one dose, phlegm sounds cease, pain disappears, and swelling vanishes completely; after two doses, full recovery occurs. Shudi, Shanzhuyu, and Wuweizi are purely sacred herbs for tonifying Kidney Water; Fuling and Shanyao benefit Essence (Jing) and promote diuresis, assisting Rougui in descending; Yuanshen eliminates floating Fire above; Baijiezi resolves obstructive Phlegm (Tan). With the Upper Jiao (Shang Jiao) cleared and the Lower Jiao (Xia Jiao) warmed by Rougui’s heat, how could Dragon-Lei Fire (Long Lei Zhi Huo) fail to return to Ming Men? One dose brings life, possessing mechanisms beyond human comprehension, surpassing Even-Numbered Rehmannia Pill (Ba Wei Di Huang Wan). If throat swelling causes complete obstruction, preventing even a spoonful of water from passing, although this divine formula exists, where can it be applied? I have another method: use one Aconite Lateralis Radix Praeparata (Fuzi) and 5 qian Psoralea Fruit (Pogu Zhi). Grind each into powder, mix into a paste-like plaster, spread on cloth like a patch, size of a teacup lid. Apply to the center of the sole (Yongquan acupoint area), warm with fire for one shichen (two hours). The throat will relax, opening a passage for medication. This wonderful method must also be known.
