（论二首方三首）
师曰。病有奔豚。有吐脓。有惊怖。有火邪。此四部病。皆从惊发得之。
〔补注〕此仲景言奔豚之始本于惊。故并及他病之亦因于惊者。夫奔豚。水兽也。
奔豚证。肾病也。经曰。东方肝木病。发惊骇。夫肝为火之母。故肝病。则不足以生
君火。而所胜者侮之也。肝为水之子。故肝病。则必至于扰肾水。而所生者顾之
也。厥阴脏为藏血之地。惊则气凝。气凝则血滞。故厥阴篇有呕家痈脓。脓尽自
愈也。阳明土本畏木者也。木得邪助。下克斯土。故传而为惊怖。所以经谓见肝
之病。当先实脾也。至肝病已不得水之滋养。必热甚生风。故火炽而未得熄焉。
要之皆因于惊。而随人之所虚以致病焉耳。
师曰。奔豚病从少腹起。上冲咽喉。发作欲死。复还止。皆从惊恐得之。
〔补注〕夫惊者。实有可畏触于我也。因其可畏而惴惴焉恐。惕惕焉惧。则曰恐。故
惊则伤心。恐则伤肾。肾为作强之官。受伤则邪气斯盛。心为神明之出。受伤则
正气以衰。水本克火者也。于是肾邪欲上凌心。斯从少腹而上冲咽喉也。何也
夫少阴脉循喉咙。因其所系之经。而上冲殊便。纵使土可制水。乃由惊病肝。则
木气足以胜土。且因惊病心。则火气又不足以生土。然则水气之止。亦其势衰
而复还耳。岂诚阳明太阴足以堤防之耶。
奔豚。气上冲胸。腹痛。往来寒热。奔豚汤主之。

〔补注〕气上冲胸。较冲咽喉稍缓。然腹痛。明系木来乘土。若往来寒热。少阳本病。
以厥阴与少阳相表里也。故以作甘者益土为制水。半夏、生姜消散积滞。以辛
温去寒。以苦寒解热。当归益营。芍药止痛。凡发于惊者。皆以本汤主治。即以病名汤。

〔补注〕汗本心之液。发汗而脐下痛悸者。心气虚而肾气动也。肾邪欲上凌心。故
脐下先悸。取用茯苓直趋肾界以泄其水气。故真武汤以此为君。尚能摄外散
之水。坐收北方。况于少阴藏中欲作未作者耶。

(There are two discussions and three formulas in total.)
The Master said: There are diseases of Ben Tun (Rushing Pig), vomiting of pus, fright and terror, and fire pathogen. These four categories of diseases all arise from fright and shock.
[Supplementary Note] This is Zhongjing stating that the origin of Ben Tun lies in fright, thus also mentioning other diseases caused by fright. Ben Tun refers to a water beast. The syndrome of Ben Tun belongs to Kidney disease. The Classics state: "When Liver Wood in the East becomes diseased, it manifests as fright and alarm." Since the Liver is the mother of Fire, when the Liver is diseased, it fails to adequately generate Ministerial Fire, and the element that it normally controls may reverse to oppress it. The Liver is the son of Water; therefore, Liver disease inevitably disturbs Kidney Water, while its offspring tends to protect it. The Jueyin organ is the residence for storing blood. Fright causes Qi stagnation; Qi stagnation leads to Blood stasis. Thus, in the Jueyin chapter, it is mentioned that patients with carbuncles and pus vomiting will recover naturally once the pus is exhausted. Yangming Earth naturally fears Wood control. If Wood is aided by pathogens, it attacks Spleen Earth below, transmitting into fright and terror syndromes. Hence, the Classics say: "When seeing Liver disease, one should first strengthen the Spleen." Once Liver disease results in a lack of nourishment from Water, heat must become excessive generating wind, so the blazing fire cannot be extinguished. In summary, all these conditions stem from fright, manifesting according to the specific deficiency locations in the individual.
The Master said: Ben Tun disease begins in the lower abdomen, rushing up to the throat. During an attack, the patient feels as if death is imminent, after which it subsides and stops. All such cases arise from fright and shock.
[Supplementary Note] Fright implies being genuinely terrified by external stimuli. Due to this fear, one feels anxious and fearful, which is termed "terror" (Kong). Therefore, fright injures the Heart, and terror injures the Kidney. The Kidney is the official of strength and vigor; when injured, evil Qi becomes prevalent. The Heart is the residence of the Spirit; when injured, righteous Qi declines. Water naturally overcomes Fire. Consequently, Kidney evil desires to ascend and overwhelm the Heart, which explains why Qi rushes from the lower abdomen up to the throat. Why? Because the Shaoyin meridian circulates along the throat, making upward rush convenient along its connected pathway. Although Earth can control Water, because fright injures the Liver, Wood Qi is sufficient to overcome Earth. Furthermore, because fright injures the Heart, Fire Qi is insufficient to generate Earth. Thus, the cessation of Water Qi is merely due to its declining momentum returning, rather than truly being dammed by Yangming or Taiyin (Spleen/Earth).
Ben Tun disease, characterized by Qi rushing to the chest, abdominal pain, and alternating chills and fever, is primarily treated with Ben Tun Tang.
Ben Tun Tang Formula
Gancao (Licorice Root), Xiong (Ligusticum Chuanxiong Rhizome), Danggui (Angelica Sinensis Radix) (each 2 liang), Banxia (Pinellia Tuber) (4 liang), Huangqin (Scutellaria Root) (2 liang), Shengge (Pueraria Root) (5 liang), Shaoyao (Peony Root) (2 liang), Shengjiang (Fresh Ginger) (4 liang), Ganligen Baipi (Bark of Prunus Spinosa Root, White Part) (1 sheng).
These nine ingredients are decocted in 2 dou of water, reduced to 5 sheng. Take 1 sheng warm, three times daily and once at night.
[Supplementary Note] Qi rushing to the chest is slightly milder than rushing to the throat. However, abdominal pain clearly indicates Wood attacking Earth. Alternating chills and fever is a fundamental Shaoyang disease, as Jueyin and Shaoyang are exterior-interior pairs. Therefore, sweet herbs are used to tonify Earth to control Water; Banxia and Shengjiang dissipate accumulation; pungent-warm herbs dispel cold; bitter-cold herbs resolve heat. Danggui nourishes Ying (Nutritive) Qi, and Shaoyao alleviates pain. Any condition arising from fright is primarily treated with this formula, named after the disease.
After sweating therapy, if pricking with heated needles induces sweat, and the needle site becomes cold, presenting with nodular redness, Ben Tun will certainly develop, with Qi rushing from the lower abdomen to the heart. Moxibustion of one cone on each nodule should be performed, followed by Guizhi Jia Gui Tang.
Guizhi Jia Gui Tang Formula
Guizhi (Cinnamon Twig) (5 liang, peeled), Shaoyao (Peony Root) (3 liang), Shengjiang (Fresh Ginger) (3 liang), Gancao (Licorice Root) (2 liang, honey-fried), Dazao (Jujube Fruit) (12 pieces).
These five ingredients are decocted in 7 sheng of water over low heat, reduced to 3 sheng. Strain and take 1 sheng warm.
[Supplementary Note] Ben Tun is the evil of the North Kidney. Using heated needles to induce sweat may be improper, but how does this relate to Shaoyin to cause Ben Tun? It is because Taiyang and Shaoyin are exterior-interior partners. Cold invading the needle site causing nodular redness indicates that previous pathogens were not dispersed, and new pathogens have re-entered. Only Guizhi can subdue Kidney evil; hence, extra Guizhi is added to Guizhi Tang to release exterior wind pathogens externally and vent interior Yin cold internally. Moxibustion on each nodule eliminates swelling caused by cold.
After sweating therapy, if palpitations occur below the umbilicus, indicating impending Ben Tun, it is primarily treated with Fuling Guizhi Gancao Dazao Tang.
Fuling Guizhi Gancao Dazao Tang Formula
Fuling (Poria) (8 liang), Gancao (Licorice Root) (2 liang, honey-fried), Dazao (Jujube Fruit) (15 pieces), Guizhi (Cinnamon Twig) (4 liang).
These four ingredients are decocted in 1 dou of Ganlan Water (Agitated Water). First boil Fuling until the volume reduces by 2 sheng, then add remaining herbs. Boil to obtain 3 sheng. Strain and take 1 sheng warm, three times daily.
[Supplementary Note] Sweat is the fluid of the Heart. Palpitations below the umbilicus after sweating indicate Heart Qi deficiency and stirring of Kidney Qi. Kidney evil desires to overwhelm the Heart, causing initial palpitations below the umbilicus. Fuling is chosen to directly target the Kidney realm to drain dampness; thus, in Zhenwu Tang, Fuling serves as the sovereign herb, capable of capturing scattered exterior fluids and consolidating Northern Water. How much more so for impending Ben Tun within the Shaoyin storehouse?
Method for preparing Ganlan Water: Take 2 dou of water, place in a large basin, and agitate with a ladle until thousands of pearl-like bubbles form and chase each other on the surface. Use this water.
