Differentiation of Taiyin Disease Patterns and Treatment
Holistic Paraphrase
The Taiyin disease discussed in this chapter (in the Six Meridian differentiation system, the disease is located in the Spleen, predominantly a pattern of internal deficiency-cold due to insufficiency of spleen yang and exuberance of cold-dampness) mainly reflects dysfunction of the Spleen in its transporting and transforming functions. The typical manifestations of Taiyin disease include: abdominal distension and fullness, vomiting, inability to eat, diarrhea that worsens progressively, sometimes with abdominal pain; if purgation is mistakenly applied, it will further damage the interior, manifesting as hard and uncomfortable binding below the sternum in the epigastric region.
The Taiyin wind-stroke pattern manifests as vexing heaviness and pain in the four limbs; regarding the pulse, it is slightly faint on superficial palpation and choppy on deep palpation, yet the pulse body is relatively long—this indicates that healthy qi is gradually recovering and pathogenic qi is about to retreat, suggesting that the disease is approaching resolution. If the pulse is floating in Taiyin disease, it indicates concomitant exterior pathogen, and diaphoresis may be applied, making Cinnamon Twig Decoction (Guizhi Tang) appropriate.
Spontaneous diarrhea without thirst belongs to Taiyin disease, because there is cold in the spleen viscus; the warming method should be used, making Center-Regulating Decoction (Lizhong Tang) or Counterflow Cold Decoction (Sini Tang) and similar formulas for warming the middle and dissipating cold appropriate. In cold damage, if the pulse is floating and relaxed, and the hands and feet are naturally warm, the disease is associated with Taiyin. Taiyin disease inherently has a tendency toward jaundice; if urination is spontaneous and free, dampness has a pathway of elimination, making jaundice less likely to develop. By the seventh to eighth day, even if there is sudden vexation and diarrhea more than ten times daily, it will often stop on its own, because spleen yang is recovering, healthy qi is being fortified, and the putrid and turbid pathogenic accumulation in the intestines is being expelled.
Originally a Taiyang disease, if the physician instead applied purgation, resulting in abdominal fullness with periodic pain, this is a Taiyin disease, and the original text indicates Cinnamon Twig Plus Peony Decoction (Guizhi Jia Shaoyao Tang) as the main treatment; if the abdominal pain is severe with palpable firm fullness, Cinnamon Twig Plus Rhubarb Decoction (Guizhi Jia Dahuang Tang) is the main treatment. In Taiyin disease with a weak pulse and persistent loose stools, even if the condition requires Rhubarb or Peony, the dosages should be reduced, because the stomach qi is weak and easily disturbed by medicinals.
In Taiyin disease, if instead there is hard stool and abdominal distension, this indicates that spleen qi cannot transport and transform, making Atractylodes Macrocephala, Immature Bitter Orange, Dried Ginger, and White Honey Decoction (Baizhu Zhishi Ganjiang Baimi Tang) appropriate; if there is no abdominal distension but instead shortness of breath, Astragalus Five-Substance Plus Dried Ginger and Pinellia Decoction (Huangqi Wuwu Jia Ganjiang Banxia Tang) is appropriate. In Taiyin disease with thirst and desire to drink water, but vomiting immediately after drinking, this indicates water retention lodged above the diaphragm, making Pinellia and Poria Decoction (Banxia Fuling Tang) appropriate. In Taiyin disease with diarrhea and thirst, and a deficient, faintly rapid pulse, this indicates injury to body fluids, making Ginseng, Atractylodes, Peony, and Licorice Decoction (Renshen Baizhu Shaoyao Gancao Tang) appropriate. In Taiyin disease without vomiting or diarrhea, but with only great abdominal distension, this indicates qi stagnation due to spleen qi excess, making Magnolia Bark Four-Substance Decoction (Houpo Siwu Tang) appropriate. In Taiyin disease without vomiting or distension, but with fecal incontinence that cannot be controlled, this is a deficiency pattern, making Center-Regulating Plus Astragalus Decoction (Lizhong Jia Huangqi Tang) appropriate.
In Taiyin disease with nausea but inability to vomit, diarrhea that is sometimes severe and sometimes mild, and a floating-choppy pulse, Cinnamon Twig Decoction Minus Peony Plus Poria and Atractylodes Decoction (Guizhi Qu Shaoyao Jia Fuling Baizhu Tang) is appropriate. In Taiyin disease with vomiting, cold abdominal pain, borborygmus with diarrhea, and a deep-tight pulse, Minor Bupleurum Plus Poria and Atractylodes Decoction (Xiaochaihu Jia Fuling Baizhu Tang) is appropriate. In Taiyin disease with retention of undigested food, and a slippery, substantial pulse, the purgative method may be used, making Qi-Subduing Decoction (Chengqi Tang) type formulas appropriate; if the stool is loose, Magnolia Bark, Immature Bitter Orange, Atractylodes, and Licorice Decoction (Houpo Zhishi Baizhu Gancao Tang) is appropriate. The period in which Taiyin disease tends toward recovery is approximately between the hour of Hai (9–11 PM) and the hour of Chou (1–3 AM).

🧠 In-Depth Understanding
Core Principles 💡
- Taiyin governs the Spleen, deficiency-cold as the root: The outline of Taiyin disease—"abdominal fullness with vomiting, inability to eat, diarrhea that progressively worsens, and periodic abdominal pain"—is centered on insufficiency of spleen yang and internal stagnation of cold-dampness🌊. The Spleen governs transportation and transformation; when yang is deficient, grains and water cannot be transformed, and clear and turbid are not separated, thus producing distension, vomiting, and diarrhea.
- Treating Taiyin requires warming🔥: For spontaneous diarrhea without thirst and cold in the viscera, treat by warming the middle and dissipating cold, using Center-Regulating or Counterflow Cold formulas; erroneous purgation further damages yang, producing "hard binding below the chest."
- Taiyin is the counterpart of Yangming: Yangming predominantly involves excess-heat, while Taiyin predominantly involves deficiency-cold, giving rise to the saying "Excess manifests in Yangming, deficiency manifests in Taiyin." However, Taiyin may also present with excess manifestations such as "spleen qi excess" or "retention of undigested food," indicating that pattern differentiation cannot be rigid.
- Concomitant exterior, water retention, or stagnation are managed separately: With a floating pulse indicating concomitant exterior, use Cinnamon Twig Decoction to harmonize the nutritive and defensive layers; with water retention stalled above the diaphragm, use Pinellia and Poria Decoction to transform fluid and promote diuresis💨; with qi stagnation and great abdominal distension, use Magnolia Bark Four-Substance Decoction to move qi and relieve fullness; with retained food and a substantial pulse, use Qi-Subduing type formulas to guide out stagnation, while carefully attending to the strength of stomach qi.
- "Spleen becoming replete" is the return of healthy qi: Diarrhea more than ten times daily that ceases on its own is not worsening of the condition, but rather recovery of spleen yang and expulsion of putrid matter. The ancients had some awareness of distinguishing this "eliminative reaction" from true collapse, but clinical practice still requires extreme caution.
- Examples of formula principles🌿: Cinnamon Twig Plus Peony Decoction doubles the Peony, emphasizing relaxation of tension and relieving pain; Cinnamon Twig Plus Rhubarb Decoction adds a small amount of Rhubarb to unblock substantial stagnation without departing from harmonizing the nutritive and defensive layers; Atractylodes Macrocephala, Immature Bitter Orange, Dried Ginger, and White Honey Decoction warms and moves spleen qi, moistens the intestines, and moves stagnation; Center-Regulating Plus Astragalus Decoction supplements qi and secures containment, treating fecal incontinence.
Modern Perspectives 🌟
- The abdominal fullness, vomiting, inability to eat, and diarrhea of Taiyin disease bear symptomatic resemblance to chronic gastrointestinal hypofunction, dyspepsia, diarrhea-predominant irritable bowel syndrome, and the recovery phase of chronic enteritis in modern medicine, but they cannot be directly equated.
- The ancients observed the difference between "spontaneous diarrhea without thirst" and "diarrhea with thirst," suggesting clinical observational value in assessing fluids and cold-heat based on thirst; modern medicine places greater emphasis on objective assessment through dehydration status, electrolytes, and infectious markers.
- "Free urination prevents jaundice" reflects an early understanding of the relationship between water-dampness metabolism and jaundice, which is not entirely the same as the modern understanding of bilirubin metabolism and fluid balance, yet the concept of "giving dampness a pathway of elimination" has reasonable merit.
- The "diarrhea ceasing on its own" and "putrid matter should be expelled" in this chapter should not be interpreted as all diarrhea being detoxification; acute diarrhea, high fever, bloody stools, severe abdominal pain, and significant dehydration require immediate medical attention.
- The "resolution period of Taiyin disease from Hai to Chou" belongs to ancient chronomedicine observations and may suggest a relationship between nighttime spleen-stomach repair and circadian rhythms, but it lacks modern evidence-based support and should not be exaggerated.
Health Preservation Insights ⚡
- Eat with moderation, especially avoiding excessive cold-raw, greasy, or hard-to-digest foods, to prevent injury to spleen yang.
- Keep the abdomen warm and avoid invasion of external cold-dampness.
- Maintain emotional equanimity and reduce excessive rumination, to prevent qi stagnation from affecting spleen-stomach transportation and transformation.
- Maintain regular作息, rest quietly during the hours of Hai to Chou (approximately 9 PM to 3 AM), and avoid staying up late.
- If recurrent or worsening abdominal distension, diarrhea, bloody stools, or weight loss occur, seek medical attention promptly rather than self-administering classical formulas.
