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。
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.
