The above two ingredients are boiled in seven sheng of water until three sheng remain. Take one sheng warm; the illness will be cured immediately upon swallowing.
For hiccups (Yue Ni), Ju Pi Zhu Ru Tang (Tangerine Peel and Bamboo Shavings Decoction) is the primary treatment.
Ju Pi Zhu Ru Tang Formula:
Ju Pi (Tangerine Peel, 2 sheng), Zhu Ru (Bamboo Shavings, 2 sheng), Da Zao (Jujube, 30 pieces), Sheng Jiang (Fresh Ginger, half jin), Gan Cao (Licorice Root, 5 liang), Ren Shen (Ginseng Root, 1 liang).
The above six ingredients are boiled in ten dou of water until three sheng remain. Take one sheng warm, three times a day.
[Commentary]: The Middle Jiao refers to the Spleen and Stomach. When Earth Qi (Spleen/Stomach) is deficient, Wood Qi (Liver/Gallbladder) from below can overact upon it, causing Grain Qi to fail to circulate freely, transforming into hiccups.
Ju Pi regulates the Qi of the Middle Jiao, promoting its ascending and descending movements. Ren Shen and Gan Cao tonify the deficiency of Earth. Sheng Jiang and Da Zao promote the circulation of Grain Qi and disperse rebellious Qi. Zhu Ru is cool in nature and possesses the correct Qi of Metal; it is used to descend the Wind-Heat of Gallbladder Wood.
When the Qi of the Six Fu Organs fails at the exterior, symptoms include cold hands and feet, upward rushing of Qi, and curling up of the legs. When the Qi of the Five Zang Organs fails within, symptoms include uncontrollable diarrhea. In severe cases, there is numbness of the hands and feet.
[Commentary]: The Six Fu Organs govern the exterior and belong to Yang; the Five Zang Organs govern the interior and belong to Yin. Yang corresponds to Wei Qi (Defensive Qi), and Yin corresponds to Ying Qi (Nutritive Qi). When the Qi of the Six Fu Organs fails, Wei Qi fails first to circulate at the exterior, hence cold hands and feet. Yang governs ascending; in respiration, it manifests as exhalation. If external Qi is severed, Qi rushes out and does not return, leading to the severance of lower Qi. Lower Qi failure causes tendon tension, hence curled legs. When the Qi of the Five Zang Organs fails, Ying Qi fails first to circulate within, leading to the departure of Yin Qi. Since stool belongs to Yin, uncontrollable diarrhea occurs. In severe cases, blood leaves its vessels, causing numbness of the hands and feet.
In diarrhea with a deep and wiry pulse, there is a sensation of heaviness in the rectum. A large pulse indicates the condition has not ceased. A weak and rapid pulse indicates it is about to stop spontaneously; even if fever is present, death will not occur.
[Commentary]: Zhang Zhongjing notes in the Jueyin syndrome section of *Shanghan Lun*: Deep pulse indicates disease in the interior; wiry pulse indicates tension. Interior Qi deficiency leads to rectal heaviness. A large pulse indicates disease progression, meaning diarrhea has not stopped. A weak and rapid pulse indicates pathogenic factors are fading and Yang Qi is recovering, signaling that diarrhea is about to stop. Although fever is present, it is due to Yang overcoming Yin, not pathogenic rebellion. Cheng Wuji's commentary states this. However, if weak Yin cannot overcome returning Yang, severe fever requires treatment, though death is unlikely. Great heat herbs should probably be avoided. *Neijing* states: "Diarrhea with fever indicates death." Nevertheless, this applies not only to Jueyin but also Shaoyin diarrhea. *Shanghan Lun* states: "With tight pulse and diarrhea, if the pulse suddenly becomes slight and hands/feet warm, diarrhea heals itself." It also states: "If hands/feet are not cold during diarrhea but instead feverish, death will not occur." These refer to Shaoyin diarrhea, not dysentery (Li Xia). Dysentery is mostly heat-related; if accompanied by fever, it is difficult to treat.
In diarrhea with cold hands and feet and absent pulse, if moxibustion does not warm the limbs and the pulse does not return, but mild wheezing appears, death ensues. If the Shaoyin pulse is weaker than the Fuyang pulse, it is a favorable sign.
[Commentary]: Hands and feet are the root of all Yang meridians, from which the twelve meridians originate. Theory states: Pulse is the house of Blood; Qi warms, and Blood nourishes. Qi controls pulse movement; Blood fills the pulse vessel. Blood cannot reach on its own but relies on Qi for transport. Qi is Yang/Fire. If Yin-Cold is excessive, Yang Fire declines, failing to distribute through meridians, causing fluid stagnation and diarrhea, resulting in absent pulse and cold limbs. If residual Yang remains rooted internally, moxibustion can guide this solitary fire to distribute through meridians; warmth of limbs indicates survival. If Yang is already extinct in the organs, breathing ceases; applying moxibustion may cause rootless Yang to flare up with the moxa fire, leading to wheezing and collapse, hence death. Fuyang pulse belongs to Stomach (Earth); Shaoyin pulse belongs to Kidney (Water). "Fu" means being overcome. If Shaoyin is overcome by Fuyang, post-heaven Yang still exists, and Yin-Cold can be reversed. Zhang Zhongjing says absent pulse in diarrhea belongs to Shaoyin; moxa Shaoyin points. Though unspecified here, since listed under Jueyin, Jueyin points should likely be moxaed.
In diarrhea with slight fever and thirst, and a weak pulse, spontaneous recovery is expected.
[Commentary]: This clause is also in the Jueyin section. Comparing with the previous clause on fever and diarrhea, they appear similar but differ. Weak and rapid pulse indicates Yang recovery and dominance, merely stating non-fatal. Here, solely weak pulse indicates Yin retreat and Yang recovery, manifesting as slight fever externally and thirst internally. It differs from severe heat overcoming Yin, hence spontaneous recovery. However, diagnosis requires precision; fever and thirst vary. For example, in Shaoyin Cold Damage after five-six days, self-diarrhea with thirst and white urine indicates Kidney deficiency seeking water; this is a variation, not easily summarized.
In diarrhea with a rapid pulse, slight fever, and sweating, spontaneous recovery is expected. If the pulse is tight, the disease is unresolved.
[Commentary]: In Jueyin syndrome, diarrhea is a Yin syndrome; rapid pulse is a Yang sign. Yin syndrome showing Yang pulse indicates life. Slight fever and sweating indicate Yin Qi is unblocked.
Furthermore, the text implies the principle of Yin-Yang retreat and return. *Neijing* states: Below Jueyin lies Shaoyin. Jueyin represents the end of two Yins where Yang returns. Yin is root, Yang is branch. Following root brings cold; following branch brings heat. Thus, Jueyin treats via the middle Qi (Shaoyin). This diarrhea stems from excessive root Yin-Cold. Slight fever reflects returning branch Yang-Fire. Return drives internal Yin pathogens to the exterior, dispersing via fever and sweat. Harmony restores health without treatment. Tight pulse indicates Cold dominance, hence unresolved.
In diarrhea with rapid pulse and thirst, spontaneous recovery is expected. If it does not improve, pus and blood will appear in stool due to Heat.
[Commentary]: In *Shanghan Lun* Shaoyin section, diarrhea with pus/blood is treated as deficiency-cold using Taohua Tang. Stagnation is treated with acupuncture. Why does Jueyin diarrhea involve pus/blood? Because of rapid pulse and heat. Shaoyin Taohua Tang cases have non-rapid pulses. Here, rapidity arises not from initial heat but from Yin excess followed by Yang recovery overcoming Yin. Rapid pulse and thirst indicate Yang recovery can dispel Yin-Cold, leading to recovery. If it persists, Yang recovery was excessive, overpowering Yin and forcing Yang-Heat to expel pus/blood. This differs from the previous clause (slight fever/thirst/weak pulse) where weak pulse means mild heat insufficient to overcome Yin, merely harmonizing. Now, rapid pulse with persistent diarrhea forms "Xie Re" (Collateral Heat) diarrhea.
In diarrhea with a reverse wiry pulse, fever, and sweating, spontaneous recovery is expected.
[Commentary]: The pulse was initially not wiry but became so, hence "reverse wiry." Wiry pulse is light and empty, characteristic of Spring, indicating Shaoyang Qi rising. Yang Qi, long suppressed by Yin-Cold and sinking to form diarrhea, now rises to attack Yin pathogens, driving them to the exterior via sweating, curing diarrhea. This differs from the previous clause (rapid pulse/slight fever/sweat) but shares the mechanism of resolution via the exterior.
In diarrhea with flatus, benefit from promoting urination.
[Commentary]: Diarrhea with flatus involves Qi and pathogens moving downward together. Due to failed Qi transformation, Water and Grain are not separated, merging in the Lower Jiao to cause diarrhea. Once the anterior Yin (urinary tract) opens, Yang Qi moves; Qi movement separates Water and Grain, stopping diarrhea.
In diarrhea, if the Cun pulse is reverse floating and rapid, while Chi pulse is naturally choppy, pus and blood will inevitably appear in stool.
[Commentary]: In *Shanghan Lun* Jueyin chapter: Cun probes Yang, Chi probes Yin. Yang is Qi, Yin is Blood. Diarrhea is Yin-Cold, so pulse should be deep. Reverse floating/rapid Cun indicates Yang excess above, failing to harmonize with Yin below. Blood fails to harmonize with Qi, failing to nourish meridians or store in Liver, scattering into intestines, causing choppy Chi pulse. Blood stagnates into pus. It must be drained.
In diarrhea with undigested food, do not attack the exterior. Sweating will cause abdominal fullness.
[Commentary]: Cheng Wuji notes: Diarrhea belongs to Stomach deficiency. Stomach is the mansion of fluids; sweating depletes fluids, worsening Stomach deficiency and causing fullness. Why is this in Jueyin rather than Yangming/Taiyang? Undigested food resembles Sun Xie (grain diarrhea). *Neijing* states: "Clear Qi sinking below generates Sun Xie." Clear Yang Qi arises from Liver Wood, governed by Shaoyang as the source of life. It should ascend. If it sinks, Grain Qi cannot lift, causing undigested food exit. Clear Yang sinking means Shaoyang hides within Jueyin. Instead of stimulating Shaoyang from Jueyin, attacking the innocent exterior forcibly dissipates Stomach Grain fluids, causing deficiency and fullness.
[Supplemental Debate]: Jueyin diarrhea differs from ordinary diarrhea. Named Jueyin because pathogen transmitted to this meridian. Why diarrhea? Jueyin travels from interior, thus prone to diarrhea. It has specific manifestations. Why not in Taiyang/Yangming? Those involve collateral heat, prioritizing interior rescue. Mr. He missed this point.
In diarrhea with deep and slow pulse, slight facial redness, slight body fever, and undigested food,郁冒 (vertigo/fainting) and sweating will occur before resolution. Patient likely has slight cold limbs. Reason: Facial redness ("Dai Yang") indicates lower deficiency.
[Commentary]: Cheng Wuji notes: Undigested food/deep-slow pulse indicates interior cold. Facial redness/slight fever indicates exterior unresolved. Patient becomes cold due to lower deficiency; exterior pathogen resolves. At sweating time, interior deficiency causes vertigo before sweating resolves. I argue Zhang Zhongjing describes Six Meridians progressing from exterior to interior. Can slight fever simply mean exterior unresolved? Perhaps pathogen entered Jueyin. Jueyin transforms into interior cold, repelling Yang outward. Interior cold causes undigested food/diarrhea and slight cold limbs. Yang repelled outward causes slight fever; repelled upward causes facial redness. "Lower deficiency" means lack of Yang below. Yang seeks recovery, entering deeply to struggle with Yin. Yin cannot reject but scatters Yang, preventing smooth flow, causing stifled heat and confusion (vertigo). After vertigo, Yang wins, Yin exits as sweat.
After diarrhea, if pulse vanishes and limbs are cold, but pulse returns and limbs warm later, life is preserved; if pulse does not return, death ensues.
[Commentary]: Also in Jueyin section. Pulse reflects Qi/Blood. Diarrhea with vanished pulse indicates loss of both Yin and Yang. Qi/Blood nourish Spirit. Loss of Qi/Blood leads to vanished pulse. Temporary return with warm limbs shows Qi/Blood merely paused, hence survival. No return means loss, hence death. Survival implies treating Qi/Blood and stopping diarrhea, not spontaneous cure. As in previous clause, moxa helped. Shaoyin undigested food/cold limbs/micro-pulse uses Tongmai Sini Tang. If pulse doesn't return after diarrhea stops, add Ren Shen to save lost blood. Two meridians differ, but cold/pulseless state is same. Here, diarrhea stops, limbs warm, pulse returns, allowing treatment.
In diarrhea with abdominal fullness and body pain, first warm the interior, then attack the exterior. Warm interior with Sini Tang; attack exterior with Guizhi Tang.
[Commentary]: From Jueyin section. Interior deficiency-cold causes diarrhea/fullness; exterior pathogen causes body pain. Diarrhea is severe, so treat interior first. Similar to *Shanghan Lun* Taiyang case where mistaken purgation caused undigested food/body pain; treat interior with Sini Tang first, then exterior with Guizhi Tang once bowels normalize.
In diarrhea with normal pulses in all three positions, but hardness upon pressing the epigastrium, urgent purgation is needed using Dachengqi Tang.
[Commentary]: *Shanghan Lun* reads "hard." Note: Diarrhea pulse should be micro; normal pulse indicates interior excess. Normal pulses here mean Qi leakage, not harmony. Food retention or cold-heat knotting in Middle Jiao causes hardness/excess. Use Dachengqi Tang to purge.
In diarrhea with slow and slippery pulse, it is excess. Diarrhea will not stop; urgent purgation with Dachengqi Tang.
[Commentary]: Cheng Wuji notes: Slow pulse from dry food; slippery pulse indicates substantial Grain Qi. Spleen/Stomach fail to digest Water/Grain, causing diarrhea. Dachengqi Tang removes retention, stopping diarrhea.
In diarrhea with reverse slippery pulse, something must be expelled; diarrhea stops upon purging, using Dachengqi Tang.
[Commentary]: Diarrhea is deficiency; slippery pulse is excess. Reverse slippery pulse in diarrhea indicates need to expel. Previous clause had slow pulse due to interior excess blocking Qi; this has slippery pulse indicating desire to expel. Both are tangible excesses, hence both use Dachengqi Tang.
If diarrhea recurs at the same year/month/day/hour after recovery, it is because the pathogen was not fully eliminated. Purge it using Dachengqi Tang.
[Commentary]: Accumulations caused by seasonal Qi reside in corresponding Zang organs. After diarrhea stops, if residue remains, and season changes, organ Qi wanes, hiding accumulation. When the season returns, Qi peaks, activating accumulation, causing recurrence. Gastrointestinal accumulation requires purgation.
In diarrhea with delirium, there is dry fecal mass; Xiao Chengqi Tang is indicated.
[Commentary]: *Shanghan Lun* places delirium/dry feces in Yangming. Here in Jueyin. Cheng Wuji notes delirium/dry feces is Stomach excess, diarrhea is Intestine deficiency, omitting Jueyin reason. Yangming usually lacks diarrhea unless combined with Shaoyang (Wood overacting on Earth). Self-diarrhea in Yangming implies Yang sinking, fatal. Yangming is double-Yang heat, associated with Dry Metal, prone to closure and fluid depletion. Heat causes delirium; dryness causes fecal mass, hence no diarrhea. Jueyin diarrhea arises from extreme Yin turning to Yang rise. Pathogenic heat enters Yin, unable to extend, descends as diarrhea. Hence many Shaoyin/Jueyin diarrheas. Yangming Dry Metal suppresses Wood, causing Jueyin diarrhea. Jueyin end transforms to rising clear Qi. *Neijing*: Clear Qi below causes grain diarrhea. From transmission view, Yangming lacks diarrhea. From meridian view, Yangming diarrhea is common. Yangming/Taiyin are exterior-interior, both related to Dampness (*Neijing*: Damp excess causes loose stool). Yangming is Dry Metal; Zang/Fu alternate dominance. Taiyin excess causes heavy body/diarrhea (Damp). Yangming excess causes stifled dry-heat and dry feces, requiring purgation, not just from external heat.
For diarrhea with pus and blood, Taohua Tang is indicated.
Taohua Tang Formula:
Chishi Zhi (Red Halloysite, 1.5 jin, sifted/crushed), Gan Jiang (Dried Ginger, 1 liang), Jing Mi (Rice, 1 sheng).
Boil three ingredients in seven sheng water until rice is cooked. Strain. Add one fangcunbi dose. Take three times daily. One dose cures; stop subsequent doses.
[Commentary]: This is Shaoyin syndrome. Kidney Water is cold, causing Water excess fighting Blood, seeping into intestines, rotting into pus. Cheng Wuji notes: Lower Jiao insecure, interior cold. Chishi Zhi astringes intestines; Gan Jiang disperses cold; Jing Mi tonifies Stomach. Chishi Zhi manages Blood/Water/leakage/astringency. Materia Medica uses it for difficult labor/placenta retention. Gan Jiang disperses cold/stops bleeding. Jing Mi guides drugs to intestines. However, some cases require draining, not astringing. Pus/blood can be drained (moving Qi/Blood). Moving Qi/Blood cannot be warmed; warming cannot move. They oppose. Zhang Zhongjing presents both; later scholars must discern. Cheng notes Yangming pus/blood is collateral heat. Do Yin meridian diseases always involve organ cold without pathogenic heat? Pathogens interact complexly. Zhang offers examples for future adaptation.
For hot diarrhea with rectal heaviness, Baitouweng Tang is indicated.
Baitouweng Tang Formula:
Baitouweng (Pulsatilla Root, 2 liang), Huang Lian (Coptis Rhizome), Huang Bai (Phellodendron Bark), Qin Pi (Ash Bark) (each 3 liang).
Boil four ingredients in seven sheng water until three sheng remain. Strain. Take one sheng warm. Repeat if ineffective.
[Commentary]: Also Jueyin syndrome. Cheng Wuji notes: Heat damages Qi; Qi deficiency causes heaviness. Lower Jiao deficiency requires bitter-cold to firm. However, heaviness varies. Previous clause (deep-wiry/heaviness) was Qi deficiency-cold failing to lift. Here, heat damages causing Qi stagnation, or Blood deficiency/stasis, or anal pain. Generally caused by dry-Qi exterior constraint. Liu Hejian states diarrhea results from dry-Qi郁 outside intestines and Dampness gathering inside. Blood movement stops stool; Qi movement relieves heaviness. Resolve dry-Qi郁 by distinguishing cold/heat. Mild heat uses acrid-warm to move Qi; severe heat uses bitter-cold to treat heat. Zhang Zihe song: Treat Fire, and Wind/Dryness resolve. Tonify Blood deficiency, move Blood stasis. Harmonized Blood/Qi resolves郁. Use bitter-cold to treat dryness, not just firm Lower Jiao deficiency. *Jingui Yaolue* cites Shaoyin/Jueyin diarrhea often. It questions why meridians are removed in miscellaneous diseases. Cold damage has transmission; miscellaneous diseases depend on location. Postpartum extreme deficiency diarrhea also uses Baitouweng Tang.
After diarrhea, if irritability worsens and epigastrium is soft upon pressure, it is deficiency irritability; Zhizi Chi Tang is indicated.
Zhizi Chi Tang Formula:
Zhi Zi (Gardenia Fruit, 14 seeds, fried), Xiang Chi (Fermented Soybean, 4 he, wrapped in silk).
Boil two ingredients in four sheng water. First boil Zhizi to 2.5 sheng, add Chi, boil to 1.5 sheng. Strain. Divide into two doses. Take one dose; stop if vomiting occurs.
[Commentary]: *Shanghan Lun* places post-treatment deficiency irritability in Taiyang. Here, it arises from diarrhea-induced deficiency irritability, noted in Jueyin. Though meridians differ, heat invading deficiency causes irritability similarly. Both use bitter Zhizi Chi Tang to vomit off pathogenic heat.
In diarrhea with undigested food, interior cold with exterior heat, sweating, and cold limbs, Tongmai Sini Tang is indicated.
Tongmai Sini Tang Formula:
Gan Cao (Licorice Root, 2 liang), Gan Jiang (Dried Ginger, 3 liang), Fu Zi (Aconite Root, raw, 1 piece), Cong Bai (Scallion White, 4 stalks).
Boil four ingredients in three sheng water until 1.2 sheng remain. Strain. Divide into two warm doses.
[Commentary]: Interior cold with exterior heat indicates Yang repelled outward. Yang cannot harmonize internally, causing undigested food diarrhea; Yin cannot harmonize externally, causing body heat.
