Medical terms: toxic blood in the intestines with rectal bleeding · chronic diarrhea · false heat, true cold (internal cold, external false heat) · spleen-kidney yang deficiency
Opening: a red face, bleeding bowels, and food that wouldn’t go down — every sign screamed “heat”
Today’s case was written down by the patient himself — not a physician, but a poor man named Zhu from Changzhou, who nearly died of his illness, and after he recovered wrote out the whole journey in careful detail and attached it to the back of Doctor Xue Lizhai’s book. He wanted later generations to see how a man who looked full of “fire” was rescued by a slow, gentle warming fire.
The illness began strangely. At first his face flushed in red patches, like wind spreading across it, his stools were dry, and he felt fire rushing upward — every sign pointed to heat. But as treatment dragged on, it turned into blood in the stool, a gurgling belly, watery diarrhea, abdominal distension and shortness of breath. In the end he could not eat at all, and he was nearly dead.
💬 Note from Doctor Luo: This is false heat, true cold — true cold on the inside wearing a mask of heat on the outside. In Doctor Xue Lizhai’s case records this pattern appears again and again; he saw enormous numbers of such patients. What makes this case precious is that the patient himself recorded it — every step is laid out plainly, with genuine feeling. You cannot fake a story like this.
Who was the patient: three years earlier, Doctor Xue Lizhai had already delivered a “prophecy”
Mr. Zhu first met Doctor Xue Lizhai three years before. At that first visit, Doctor Xue Lizhai looked at his face and said: your face is flushing in red patches — this is called “face-red as wind” (mian chi sheng feng), and it is a spleen-stomach problem. If you don’t treat it, something serious will come of it later.
Mr. Zhu worried about this, but then thought — well, maybe I’ll put it off. He gambled on luck. Three years passed.
💬 Note from Doctor Luo: Why is a red face a spleen-stomach problem? Because the spleen-stomach channels run upward and cross the face. When the spleen and stomach are weak, deficiency fire rides along the channel qi and flares up to the face. So when your face turns inexplicably red, in patches, don’t just reach for cooling herbs — first ask whether the spleen and stomach are deficient.
The illness that delay produced: liver wood attacking the spleen — red face, constipation, fire rushing up
Three years later, the illness truly arrived. Mr. Zhu’s emotions soured, his liver qi knotted up, and the wood of the liver attacked the earth of the spleen — the liver bullied the spleen-stomach, and the spleen-stomach collapsed. So came the red face, the dry, bound intestines, the fire rushing upward — on the surface, a textbook heat pattern.
But here, Doctor Luo Dalun urges us to pause and raise a question.
💬 Note from Doctor Luo: When liver wood attacks the spleen, there is indeed fire — but it is usually deficiency fire. For a person whose spleen-stomach was already weak, when deficiency fire flares up, no amount of cooling medicine will put it out. Warm the spleen and stomach a little, nourish them, and the deficiency fire withdraws by itself. So whether this was really a heat pattern at the start is very much open to doubt.
The more they cooled, the worse it got: every dose of huang lian doused another measure of yang
The physicians treating him at the time all followed the heat diagnosis: cold, bitter herbs like huang lian (coptis) to clear damp-heat, one prescription after another. The result? The illness only multiplied and worsened — the more they treated, the sicker he became.
💬 Note from Doctor Luo: Everyone sees diarrhea and immediately thinks “clear damp-heat” — this is one of the most common mistakes. Among people with long-standing diarrhea, deficiency-cold is the majority pattern. If you’ve been purging for months, how could damp-heat persist that long? Mostly it’s cold, at most with a little dampness mixed in — cold with heat tangled together. The anus burns during the diarrhea, so everyone assumes damp-heat and clears it — but the thinking is often simply wrong.
At the edge of the grave: bleeding, rumbling bowels, a swollen belly, no breath, no food
The cold herbs piled up, and Mr. Zhu’s illness grew worse and worse. First came “toxic blood descending from the viscera” (zang du xia xue) — blood in the stool, with abdominal pain. Then “rumbling bowels with gushing diarrhea” (chang ming dong xie) — his belly gurgled loudly, and everything that came out was watery. Then abdominal distension with rapid breathing (fu zhang chuan ji) — his belly swelled severely, until even breathing was hard. At the very end, he could not swallow food, and he hovered at death’s door.
Only then did he finally reach Doctor Xue Lizhai.
Doctor Xue Lizhai’s verdict: spleen-kidney deficiency — true cold within, false heat without
After examining him, Doctor Xue Lizhai cut through it with one sentence: your illness is spleen-kidney deficiency — true cold inside, false heat outside. The heat you feel on the surface is pure illusion. Where is your damp-heat? You are deficient.
💬 Note from Doctor Luo: This is the hardest moment to recognize — true cold inside, false heat outside. Outside he looks blazing hot, but inside the yang qi is already badly depleted. All that huang lian had savaged the yang of the spleen and kidney; the more the yang was wounded, the more the man looked “on fire” — and that illusion fooled every previous physician.
Anatomy of the prescription: a slow warming fire that roasted the spleen-kidney yang back
The formula Doctor Xue Lizhai wrote went in exactly the opposite direction from the previous doctors — warming and tonifying:
Ren shen (ginseng) and bai zhu (atractylodes) as the sovereign pair, with shan yao (Chinese yam) and huang qi (astragalus), to tonify the spleen and qi; gan jiang (dried ginger) and fu zi (aconite) to warm yang and scatter cold; rou dou kou (nutmeg) to warm the middle and astringe the intestines to stop diarrhea; wu zhu yu (evodia) to warm the middle and lower burner and warm the liver as well; bu gu zhi (psoralea) to warm and tonify the kidney yang of the lower burner; wu wei zi (schisandra) to astringe and stop the diarrhea; dang gui (angelica sinensis) to nourish and harmonize the blood; and fu ling (poria) to drain dampness. One whole stove of gentle fire, warming and tonifying spleen yang and kidney yang together.
💬 Note from Doctor Luo: Look at this formula — there is not one cold-natured herb in it. This is the strategy of warming and tonifying the yang of the spleen and kidney: restore the yang, the cold dissolves, the deficiency fire withdraws on its own, and the bleeding stops. Get the direction right, and the rest is just time.
The turning point: every other doctor shouted “This is fire!” — he would not be moved
When the prescription was written, the other physicians shook their heads: this is a fire illness, and you’re piling on hot herbs — adding fuel to the fire, will this ever work?
But this time Mr. Zhu would not be swayed. He knew too well: he had taken cooling medicine for a long, long time, and with every dose he grew worse, until he couldn’t even eat. Why should he believe them now? He trusted Doctor Xue Lizhai.
And so he took the medicine for about ten days — with careful diet and rest — and the bleeding stopped, the diarrhea ceased, and every symptom resolved.
💬 Note from Doctor Luo: The patient himself has the final word — he took cold-natured herbs for so long and only worsened; that is the irrefutable proof. Doctor Xue Lizhai had seen the root of his disease three years earlier — that is real skill. The other doctors only saw the “fire” in front of their eyes, but could not see the cold beneath it.
The patient’s tearful record: “Without you, Sir, I would already be a mound of yellow earth”
After he recovered, Mr. Zhu was overcome with emotion and wrote these words: “Without you, Sir, I would by now be a mound of yellow earth! Ah, your art, Sir — divine, simply divine!” Feeling he could never repay the debt of kindness, he recorded the whole course of the illness and attached it to the back of the book, hoping that patients who later met the same fate could draw guidance from it. He signed it: Zhu of Changzhou.
💬 Note from Doctor Luo: There is one more detail worth pondering. Mr. Zhu began with constipation and a red face, and only later shifted to bloody diarrhea. The commentators in the Xue Case Discriminations (《薛案辨疏》) believed it was a heat pattern at the start — but Doctor Luo Dalun deeply suspects his yang was already insufficient from the very beginning. Why? Because if the spleen-stomach had not already been weak, the cold herbs could not have wounded him so savagely. Recognizing false heat, true cold is one of the hardest passes in learning Chinese medicine — and one of the most worth practicing.
Doctor Luo’s closing note: in chronic diarrhea, don’t rush to clear damp-heat
The lesson ordinary people should remember most from this case is Doctor Luo Dalun’s plain talk:
💬 Note from Doctor Luo: Don’t trust the textbook too blindly. Textbooks say yang-deficiency diarrhea should be “undigested grains in the stool” (xia li qing gu). But in real clinical work, many people with cold-induced diarrhea pass brownish-yellow stools with a burning anus — you assume damp-heat, but it is very often just cold. So the more diagnostic information the better: look at the tongue, press the belly to feel whether it’s cool or warm, ask whether the patient prefers cold or warm drinks — the Ming-dynasty physician Doctor Zhang Jingyue summed this up in his famous “Ten Questions Song”: first ask about chills and fever, second about sweating, third about head and body, fourth about the bowels — question after question, and when the information is complete, diagnosis rarely goes wrong, and false heat/true cold can no longer hide.
Epilogue: a sharp eye for cold is what protects you
The reason Doctor Xue Lizhai dared to prescribe “warming and tonifying” is that he had seen too many patients like this. What ordinary people can do is remember this rule of experience: the longer an illness drags on, the more the body is consumed, the less yang remains, and the greater the chance that it is true cold — so a red face and blood in the stool may not be fire at all; they may well be cold. Keep this thread in mind, and the next time you meet an illness that “grows worse with every cooling herb,” you will know where to look.
