No Bowel Movement for Half a Month With a Bloated Belly? Doctor Zhang Jingyue’s Case of Yang-Deficiency Constipation (Yin Jie) — Nourish Kidney Essence First, Then Warm the Yang
Patient search terms: constipation / can’t pass stool / no bowel movement in days / bloated belly / can’t poop / constipation in the elderly / ice-cold feet
Medical terms for this condition: yin-type constipation (yin jie) · yang-deficiency constipation · true cold with false heat (zhen han jia re) · kidney essence insufficiency
Opening: the thread we left hanging last time, picked up today
Last time we talked about Doctor Zhang Jingyue’s treatment of constipation, and how the old master split the whole subject into two roads: yang-type knotting (yang jie) and yin-type knotting (yin jie). Yang jie is heat — you purge it. Yin jie is deficiency, is cold — you tonify it. Doctor Luo left a thread hanging at the end of that story: “The yin-jie case, we’ll continue tomorrow.” Today’s case is that “tomorrow.”
💬 Note from Doctor Luo: This patient was the venerable mother of Hanlin scholar Zhu — a Hanlin is a scholar admitted to the Imperial Academy, so this was the mother of an imperial scholar, and she was nearly seventy years old. One May, walking along, the old lady took a fall. A fall usually just means a few days of rest, but this old lady was never right after it — she developed chills with fever (han re): she felt freezing cold, yet when you touched her she was burning hot, running a fever. In Chinese medicine this presentation is called “cold-heat.”
Worse and worse: yin-nourishing, fire-clearing herbs that only made things worse
The moment the old lady ran a fever, the family called a doctor. The doctor took one look: isn’t this a fever? Then clear heat and nourish yin — fresh rehmannia (sheng di) to nourish yin, matched with peony root, moutan bark, skullcap and anemarrhena — all fire-clearing, yin-nourishing herbs. And the result? “Qi bing ri shen” — the illness grew more severe day by day. The more they treated, the worse she got.
💬 Note from Doctor Luo: Strange, isn’t it? Nourishing yin and clearing fire looks perfectly reasonable — how could it make things worse? When Doctor Zhang Jingyue arrived, he saw the problem at a glance. He took her pulse: all six pulses were completely weak — no strength at all in any of them. Then he looked at the person: head, face, and upper body felt hot. But ask her if she was thirsty? Not thirsty — she had no desire at all for cold water. Then he felt downward — her feet were cold to the bone: the groin was cold, the knees, the ankles, the feet — a sheet of ice. How strange: the whole body shows heat signs, so why are the legs and feet this cold?
The crucial point: Doctor Zhang Jingyue’s “yin deficiency” is not the yin deficiency you’re thinking of
Doctor Zhang Jingyue’s diagnosis is a single sentence in the original text: “Ci yin xu shou xie, fei die pu zhi wei bing, shi yin zheng ye” — “This is yin deficiency receiving evil; it is not an illness caused by the fall — in essence it is a yin syndrome.” But when people hear “yin deficiency,” they’re baffled: doesn’t yin deficiency mean internal heat? How can he call it a cold syndrome?
💬 Note from Doctor Luo: Here is a major key — anyone who reads Doctor Zhang Jingyue must get this straight: when Doctor Zhang Jingyue says “yin deficiency” or “true yin insufficiency,” most of the time he means kidney essence insufficiency (shen jing bu zu). The Huangdi Neijing (Yellow Emperor’s Inner Canon) says “yin deficiency generates internal heat” — that is the broad sense of yin. Later, as the concept of yin kept expanding, kidney essence was folded into “yin” as well. So much of what Doctor Zhang Jingyue calls yin deficiency is really kidney essence depletion. “Yin deficiency receiving evil” translates as: the kidney essence is depleted, and external evil sneaks in through the opening.
What is kidney essence? It is the root of life stored in the kidney. Once kidney essence is depleted, both kidney yin and kidney yang are insufficient — and in this old lady the yang deficiency showed more clearly, which is why it was a yin syndrome (cold syndrome). Doctor Zhang Jingyue believed the disease was not caused by the fall itself; rather, kidney essence was depleted, yang qi was insufficient, and external evil (or something resembling an external contraction) took the opportunity to enter.
The prescription: Li Yin Jian plus ginseng and bupleurum — prepared rehmannia leading the charge
The formula: Li Yin Jian (Regulate Yin Decoction) plus ginseng (ren shen) and bupleurum (chai hu). Li Yin Jian is a famous formula of Doctor Zhang Jingyue’s own creation, collected in the “New Formulas in Eight Arrays” section of Jingyue Quan Shu.
💬 Note from Doctor Luo: What herb leads Li Yin Jian? Prepared rehmannia (shu di huang). In the original formula, prepared rehmannia runs from three to five qian up to one or two liang — one to two liang is sixty grams, so the dose can go very large. It is matched with angelica (dang gui) to nourish the blood, honey-fried licorice (zhi gan cao) to tonify the spleen and stomach, plus a little dried ginger (gan jiang) or cinnamon (rou gui) — if the yang deficiency is obvious, dried ginger can be used at three qian (about nine grams), a substantial dose. The logic is very clear: a large amount of prepared rehmannia to replenish kidney essence, paired with yang-warming dried ginger and cinnamon, steering the formula toward warming the yang. This formula is indicated broadly: true yin (kidney essence) weakness presenting as bloating, vomiting, phlegm-fluid nausea, diarrhea with abdominal pain, and in women, delayed periods with blood stasis — it covers all of those.
In the indications for Li Yin Jian, Doctor Zhang Jingyue writes it out plainly: people with insufficient kidney essence who tire easily, who suddenly catch cold evil that will not disperse, and then develop fever, headache, body aches — or flushed face with a parched tongue (mian chi she jiao), or thirst without liking cold drinks, or chills along the spine and limbs — while the pulse is weak — these are “all false-heat syndromes” (xi shu jia re zhi zheng), every one of them! In such cases, “if you attack with cold, cooling herbs, the patient will die.” Doctor Zhang Jingyue added bupleurum to push the evil outward — he judged that the old lady had a bit of external contraction mixed in.
The fever broke in two doses — but then came half a month without a bowel movement, and a swelling belly
Two doses, and the fever broke — no more burning. The family breathed a sigh of relief. But a new problem arrived: the old lady had not had a bowel movement in half a month. She was only taking two or three bowls of thin congee a day, and her belly was swelling up little by little — now the whole family was terrified again. A bloated belly is never a good sign.
💬 Note from Doctor Luo: Everyone gathered to discuss it: if the bowels won’t move, it must be fire — something is stuck in the intestines, so we need rhubarb (da huang) or some other cooling laxative to push it through! Doctor Zhang Jingyue “yu jian zhi bu cong” — he flatly refused. He said: “Ru ci zhi mai, ru ci zhi nian, ru ci zhi zu” — “with a pulse like this, an age like this, feet like this” — the pulse is this weak, the age this old, the feet this cold — if you give cold, fire-clearing herbs again, “qi yuan bi bai” — her upright qi will collapse completely, and then the disease truly cannot be treated.
The turning point: the kidney abhors dryness; urgently eat acrid flavors to moisten it
So what did he do? Doctor Zhang Jingyue cited a line from the Inner Canon: “Shen wu zao, ji shi xin yi run zhi” — “the kidney abhors dryness; urgently eat acrid flavors to moisten it.” The kidney hates dryness, so hurry up and use acrid-flavored herbs to moisten it. Therefore: to the previous formula he added aconite (fu zi), and doubled the ginseng and angelica — dried ginger and aconite added, ginseng and angelica doubled, qi and blood tonified further.
💬 Note from Doctor Luo: Why is this move so clever? The old lady was not hot — she had internal exuberance of yin-cold and insufficiency of upright qi. The intestines were frozen stiff; there was no strength to move, so the stool piled up. Warm it up, and the “ice” inside melts — the bowels naturally move again. And the result? Within a few doses the bowels moved and the bloating subsided (shu ji er bian ji tong, zhang ji tui) — a few doses and the stool passed, the belly was flat, and she steadily recovered. When she was well, even the people who had opposed him conceded: Doctor Zhang Jingyue “had firmly held judgment” — he had never once used cold, cooling herbs carelessly.
Liu Wei Hui Yang Yin: Li Yin Jian plus aconite and ginseng
Using this formula as a springboard, Doctor Luo introduces another important formula of Doctor Zhang Jingyue’s: Liu Wei Hui Yang Yin (Six-Ingredient Yang-Restoring Drink) — which is simply Li Yin Jian plus aconite and ginseng.
💬 Note from Doctor Luo: Liu Wei Hui Yang Yin is one of the signature formulas of Doctor Zhang Jingyue’s warming-and-tonifying school. Its architecture: a large dose of prepared rehmannia to replenish kidney essence, a small dose of cinnamon and dried ginger to warm the yang, angelica to nourish the blood, honey-fried licorice to hold the center, plus aconite to restore the yang and ginseng to tonify qi. It fills in kidney essence on one side and steers toward restoring yang on the other. A great many people today have weakened foundations, and this approach is genuinely useful — take some time to savor these two formulas.
Three lessons: constipation is not always “excess fire”
What do we learn from this case? Doctor Luo sums up three points.
💬 Note from Doctor Luo: First, constipation is not always a heat syndrome. Don’t assume that being constipated means you’re “on fire” and grab a handful of rhubarb or senna leaves (fan xie ye) to purge yourself — yang deficiency and internal yin-cold can also cause constipation; that is exactly what “yin jie” means. Second, for yang-deficiency constipation rooted in kidney essence insufficiency, nourish the kidney essence first and then warm the yang — the effect is far better than warming the yang alone. Dried ginger and aconite by themselves may not work; but once prepared rehmannia replenishes the kidney essence, then warming the yang achieves the root treatment (gen ben zhi zhi). Third, people with depleted kidney essence and insufficient yang qi are especially prone to “cold-like” presentations — sometimes even genuine external contraction. The treatment should nourish kidney essence and warm the yang on one side, while using bupleurum, ephedra, and similar herbs to disperse the evil outward — this is what is meant by “supporting the evil out” (tuo xie wai chu).
Bonus: “supporting the evil out” is a great art — and there’s also “repelling yang”
The concept of “supporting the evil out” deserves a closer look. Doctor Zhang Jingyue proposed: when a person with depleted kidney essence catches external evil, you cannot simply scatter the evil. First you must support the upright qi and “lift” the evil outward — lift it the way you lift a heavy object — and at the same time use dispersing herbs outside, so the evil is resolved through sweat.
💬 Note from Doctor Luo: This concept was used widely by later generations — the warm-disease school used it constantly. When I lectured on the Li Xuan Si Jia Yi An (Four Physicians’ Case Records Selected by Liu), I mentioned the same approach: use fresh rehmannia and prepared rehmannia to replenish kidney essence and support upright qi, so the evil is carried outward. There is also another direction for kidney essence insufficiency — repelling yang (ge yang): when internal yin-cold is so exuberant that it repels the yang outward, you get heat above (flushed face, swollen sore throat, restless heat) and cold below (ice-cold legs and feet) — it looks like an external contraction, but it is really deficiency. This is the same territory as the Dragon-Thunder Fire (long lei zhi huo) we discussed with Yin Huo Tang (Lead the Fire Down Decoction) — that case ran in the yin-deficiency direction of kidney essence depletion; today’s case runs in the yang-deficiency direction. Both paths start from the same shortage of kidney essence. (Yin Huo Tang’s original formula actually contained no cinnamon; adding a little later made it work even better — the reasoning is exactly the same.)
The old lady was nearly seventy. That she recovered, her family said, was like snatching her life back from death. Doctor Zhang Jingyue’s pattern discrimination was precise, his foundations deep — one decisive judgment, and from start to finish he never used a single cold, cooling herb carelessly. This is a living textbook of the principle “one who is skilled at tonifying yang must seek yang within yin” (shan bu yang zhe, bi yu yin zhong qiu yang): when you tonify the yang, first fill in the foundation of yin (kidney essence).
