Opening: the illness looks entirely like a spleen-stomach problem — but Doctor Xue Lizhai said, “This is not a spleen-stomach disease”
Doctor Xue Lizhai (Xue Ji), director of the Imperial Medical College in the Ming dynasty, went back and forth using just a handful of formulas, and yet he could cure all kinds of intractable diseases. What makes today’s story special is this — the case record was written by the patient himself. After he was cured, this patient set down the whole course of the illness stroke by stroke, in far more detail than the doctor would have recorded.
💬 Note from Doctor Luo: This case is precious. When the patient writes it himself, he remembers many details very clearly, and we can see the entire journey of an illness from start to finish. He said one thing at the very beginning — the illness “looked like a spleen-stomach disease,” yet Doctor Xue Lizhai insisted: this is not a spleen-stomach disease. That is the single most valuable line in the whole case.
Who was the patient? A man who had taken a fall and whose left foot went numb
The patient was called Zhu Zuo, a Ming dynasty man from a fairly poor family. Years before, he had tripped and fallen, and at the moment of the fall there was an “audible sound” — where exactly the sound came from, he never made clear; Doctor Luo suspects it was the sound of the injury itself. Ever since, whenever he sat or stood for a long time, his left foot went numb.
💬 Note from Doctor Luo: A numb left foot after long standing or sitting looks like the qi and blood are not circulating — it is connected with the old fall: blood stasis, qi and blood failing to move freely. But there is a deeper layer underneath: people with insufficient kidney qi and insufficient yang have cold congealing inside the body, so the qi and blood can hardly move in the first place; then falling once is like frost on top of snow — the qi and blood move even worse, and the left foot goes numb. The patient knew nothing of medicine and wrote all of this down together, but in fact these events are connected.
The strange thing in summer: feet as cold as ice
Stranger than the numbness was this: in summer, both his feet were as cold as ice.
💬 Note from Doctor Luo: Notice — both feet, not just the left foot from the fall. If your feet are like ice even in summer, what does that tell you? The yang qi really is insufficient. This is not the same as the numbness from the fall — a fall may simply block the local qi and blood, but if both feet are cold in summer, it is a problem of the body’s foundation.
The turning point: drinking liquor, gulping cold water, and the belly began to make trouble
That year, in the summer of the ji-hai year, Zhu Zuo got drunk on liquor. He woke up thirsty, drank some cold water, and went back to sleep. When he woke again, he found: a blocked, stuffy mass in the right abdomen (you fu pi jie). When he pressed and massaged it, his belly gurgled and rumbled; only after massaging until it grew warm and he passed a few farts did he feel some relief.
💬 Note from Doctor Luo: The gurgling and rumbling is yang qi being insufficient — too weak to transform dampness — so the water-dampness just sits in the belly. It improves when you rub it warm and pass gas, which shows it is water-dampness and stagnant qi parked right there. Of course, a gurgling belly is not always yang deficiency — there are damp-heat types and cold-heat-mixed types, and you must tell them apart; here, combined with feet that are cold even in summer, this is water-dampness stopping because of insufficient yang qi.
Eating a bit more brings on diarrhea — and it dragged on for six years
From then on, Zhu Zuo’s problem became fixed: if his food increased even slightly, his stomach would ache and he would have pouring diarrhea (tong xie). After the diarrhea passed he felt somewhat better, but the moment he touched something cold or ate anything greasy, the diarrhea returned.
He went to see doctors, and the formula he was given — the one mentioned earlier — was Zhizhu Wan (Immature Bitter Orange and Atractylodes Pill). He took it faithfully for a stretch, with not the slightest effect. And so the illness dragged on for six years, until finally he came to Doctor Xue Lizhai.
💬 Note from Doctor Luo: This pattern — “diarrhea the moment I touch something cold, some relief after the stool passes” — is called in Chinese medicine spleen-kidney yang deficiency. Why must the kidney be included? Because when an illness drags on for a long time, it generally accumulates down into the kidney — this is not something the spleen and stomach can warm back up with a bowl of hot soup and a little extra ginger. When a disease has lasted years, you must think of the kidney.
Doctor Xue Lizhai’s diagnosis: “This is not a spleen-stomach disease — it is mingmen fire deficiency failing to generate earth”
At a single examination Doctor Xue Lizhai pronounced: “This is not a spleen-stomach disease. It is mingmen fire deficiency, failing to generate earth — deficiency-cold has made it so. If you treat only the spleen and stomach, you will be wrong.”
💬 Note from Doctor Luo: What does that mean? Look at the illness: gurgling belly, diarrhea — the symptoms are all in the spleen and stomach, but the root is not there. It is mingmen fire deficiency, kidney yang insufficiency; when fire cannot generate earth, the spleen yang becomes deficiency-cold. The mingmen fire is like the flame in a stove — if the fire is weak, the pot on top (the spleen-earth) cannot get hot. If you only fiddle with the spleen and stomach, you are treating the branch, not the root. His six years of Zhizhu Wan with no effect — that is exactly where he got stuck.
The prescription: one ingredient of Bawei Wan, and the illness was cured
Doctor Xue Lizhai said: “Take Bawei Wan” (the Eight-Ingredient Pill — Guifu Dihuang Wan, also known as Jinkui Shenqi Wan). Zhu Zuo found the reasoning sound and began taking it. Sure enough, the illness was cured.
💬 Note from Doctor Luo: How much aconite (fu zi) is in Bawei Wan? Very, very little. Here is an analogy: the kidney-essence tonics in the formula are like a barrel of oil, and the aconite is the lighted match — just a tiny bit, yet it can set the whole barrel ablaze and carry the direction of the entire formula toward warming the yang. As long as the aconite is properly processed, putting in this little amount causes no trouble at all. Even today, some people take aconite in doses of hundreds of grams — as long as it is decocted long enough, that is safe too.
The patient’s admiration: “Doctors dare not lightly use aconite — Master Lizhai is the Zhuge Liang of our day”
Zhu Zuo wrote in his case record: Bawei Wan contains aconite, which ordinary physicians “dare not lightly use” (wang gan qing yong) — fearing its toxicity. But Doctor Xue Lizhai said of aconite: “To cut the gate, seize the banner, and snatch the dying back to life — only a great general can wield it.” In other words: only an experienced, highly skilled physician dares to use it.
💬 Note from Doctor Luo: Zhu Zuo sighed: Master Lizhai is the “Wuhou” (Zhuge Liang, the great strategist) of the medical world today! This is a patient’s heartfelt reverence for the man who saved his life. Seen with today’s eyes, Doctor Xue Lizhai’s pattern-differentiation skill was indeed very high, but the little bit of aconite in Bawei Wan need not be deified. Still, this reveals an important fact about the times: by the Ming dynasty, physicians had already grown afraid to use aconite and afraid to warm the yang — and Doctor Xue Lizhai stood up to champion the idea that “yang qi matters enormously.” That is his courage.
Too poor to repay the debt of kindness: he wrote down the case and bowed himself out
Zhu Zuo’s family was poor — “jia pin bu neng bao de”, he could not afford the consultation fee or a lavish gift of thanks. So he wrote down the entire case record, stroke by stroke, recording the “marvel” of Doctor Xue Lizhai’s treatment, and bowed himself out (dun shou bai chu). It was both a thank-you and a testimony left for later generations.
Extension: diarrhea when chilled, or diarrhea at dawn — use Sishen Wan
Using this case, Doctor Luo shared an experience ordinary people can put to use: this kind of “diarrhea the moment I touch something cold,” when it has accumulated into kidney yang insufficiency — especially when you have to run to the toilet first thing after waking in the morning (wu geng xie, dawn diarrhea, also called cockcrow diarrhea) — just as the morning yang is about to rise and the yin is still heavy, you get the urge before you are even out of bed — for this, Sishen Wan (Four Spirits Pill) works especially well. Tong Ren Tang sells it in finished form under the name Roukou Sishen Wan (Nutmeg Four Spirits Pill).
💬 Note from Doctor Luo: I often recommend Roukou Sishen Wan to patients; it is generally available to buy online. For this kind of diarrhea-on-chilling that ends in kidney yang insufficiency, the results are quite good. Remember the signal: people with insufficient yang qi touch a little something cold, eat a little something oily, get a cold breeze — and the diarrhea comes pouring out.
Two lessons to take with you
Finally, Doctor Luo summed up the two most valuable lessons from this case:
First, when you see a spleen-stomach problem, if it is caused by insufficient yang qi, think of spleen-kidney yang deficiency — the root is in the kidney. Especially for chronic problems that have not healed for a very long time: when you regulate the spleen and stomach in every way and nothing works, you must consider whether the kidney yang is involved.
💬 Note from Doctor Luo: This is our clinical experience: spleen-stomach problems are generally easy to adjust, but once an illness has accumulated into the kidney, it becomes chronic and serious. Think of a building — if a wall cracks here or the wind damages a spot there, there is nothing to fear; if the foundation is damaged, that is the real catastrophe. At such a time do not be impatient — the fire of life must be relit little by little: warm the kidney yang, warm the spleen yang, and slowly consolidate the foundation.
Second, when a long-standing illness has accumulated into the kidney, treat it at the root — stoke the mingmen fire brighter, and the yang qi of the spleen-earth above will naturally be sufficient. Only then is the root problem solved.
