Opening: Doctor Xue Lizhai, this “legendary man” — how does treating illness get simpler the longer he practices?
After following this series of case records for a while, many of you may have the same impression: Doctor Xue Lizhai treats illness with the same handful of formulas, adding and subtracting a little here and there, and the results are astonishingly good — he seems almost supernatural. And yet, precisely because of this, some people in the Chinese medicine world look down on him — treatment this simple, how could it possibly work?
💬 Note from Doctor Luo: Let me say something more here. If your understanding of Chinese medicine is not deep, it is very easy to fail to see where Doctor Xue Lizhai’s true excellence lies. When you have practiced long enough, treatment ultimately comes down to just a few things: qi deficiency and blood deficiency, yin deficiency and yang deficiency, phlegm-dampness and blood stasis, and constrained liver qi. Solve those problems, and the body recovers on its own. Doctor Xue Lizhai, at the end of his cultivation, was like a martial artist who has trained to the highest level — the simpler his moves, the more powerful they became. The great way is simple (da dao zhi jian): being able to master such complex problems with such simple methods is precisely what makes a true master.
Who was the patient: a court official named Xue, passing blood from the anus
Today’s patient was an official, surname Xue. What was his illness? Blood in the stool — bright red blood dripping from the anus.
Now, when anyone sees blood in the stool, the first instinct is a heat pattern: heat forces the blood to move, so the blood is being pushed out by heat. The previous physicians accordingly prescribed cold-natured medicines such as Xi Jiao Di Huang Tang (Rhinoceros Horn and Rehmannia Decoction) — to clear damp-heat and stop the bleeding.
💬 Note from Doctor Luo: Xi Jiao Di Huang Tang is an extremely cold formula. Generally we believe that blood moves because heat breaks it loose — clear away the heat and the bleeding should stop. But this gentleman was different: the more cooling herbs he took, the more he bled. That is a signal — things are not that simple.
Symptoms: growing thinner, running a fever, unable to eat, pain after passing stool
The cooling medicine did not stop the blood; the man only grew worse:
- Emaciation — his body wasted away day by day;
- Fever with little appetite — his body felt hot, almost feverish, yet his appetite shrank;
- Tenesmus (li ji hou zhong) — his belly ached, he rushed to the toilet, and after passing stool the pain continued — unlike ordinary diarrhea, which brings relief once it comes out.
💬 Note from Doctor Luo: “Li ji hou zhong” is a classical term many people do not understand. In plain language: belly pain, the urge to go but unable to pass, and pain that persists after passing — that is tenesmus. With ordinary intestinal diarrhea, the belly relaxes once you have been to the toilet; this gentleman still hurt after passing stool, which tells us the problem is not stagnant material inside the intestines but something else entirely.
The diagnostic high point: Doctor Xue Lizhai sees it in one sentence — spleen qi sinking
Most physicians, at this point, would still be clinging to “heat.” Doctor Xue Lizhai took one look and pronounced his judgment: this is spleen qi sinking (pi qi xia xian) — the spleen qi has become deficient to such a degree that the whole qi mechanism is sinking downward.
💬 Note from Doctor Luo: This is Doctor Xue Lizhai’s brilliance. He was exceptionally good at deciding one thing: is the pathogenic qi flourishing, or is the upright qi deficient? He looked at this man — there was hardly any pathogen; it was purely upright deficiency. The spleen qi was deficient, the qi mechanism collapsed downward, the intestinal environment changed accordingly, and that is why he had both diarrhea and bleeding. If you still treat it as a heat pattern and keep clearing with cooling herbs that injure the spleen and stomach — are you not adding frost to snow?
Anatomy of the prescription: Buzhong Yiqi Tang plus blast-fried ginger — cured in one dose
Once the direction was set, the formula was remarkably simple: Buzhong Yiqi Tang (Tonify the Middle and Augment Qi Decoction) plus pao jiang (blast-fried ginger).
Buzhong Yiqi Tang — the name sounds familiar. It is Doctor Li Dongyuan’s immortal formula, tonifying qi and lifting it upward, raising the sinking qi mechanism. As for pao jiang — blast-fried ginger — it warms the middle burner and the lower burner, warming the whole system back into action.
💬 Note from Doctor Luo: Buzhong Yiqi Tang tonifies qi and lifts it up; pao jiang warms the middle and the lower burner. Is your overall function low and your temperature insufficient? I will warm you up. Is your qi too deficient and sinking? I will tonify and lift it, restoring the qi mechanism to normal operation. That was the entire prescription — one single dose, and he was cured.
Note from the commentator: the intestines are a “delicate environment”
The case itself is over in a sentence, but the principle within it — what Doctor Xue Lizhai did not spell out — Doctor Luo Dalun now fills in for us. And it begins with the intestines.
💬 Note from Doctor Luo: In Chinese medicine, part of the intestines’ function belongs to the spleen. The intestines are an extremely delicate system, part of the body’s internal environment — any change in the body’s yin-yang, cold-heat balance shows up in the intestines. Modern science tells us the gut harbors hundreds of millions of bacteria: beneficial bacteria in the majority, harmful ones in the minority, plus neutral strains that are neither clearly good nor clearly bad. These microbes are not foreign invaders; they are part of us. They help break down food and absorb nutrients — we cannot live without them.
So how did the ancients “manage” these microbes?
💬 Note from Doctor Luo: The ancients had no concept of gut flora, but their way of prescribing happened to match the principle. Spleen-tonifying herbs — shan yao (Chinese yam), lotus seeds — are “food” for the beneficial bacteria: tonifying the spleen means feeding the good microbes. Herbs that clear damp-heat — huang lian (coptis), huang bai (phellodendron), bai tou weng (pulsatilla) — restrain the harmful bacteria. That is why the ancients so often built formulas this way: a little spleen tonic plus a little damp-heat clearer, to change the intestinal environment. It was a remarkably intelligent design.
Extended reflection: why is diarrhea so complicated?
You may think diarrhea is a minor illness, but Doctor Luo says: do not underestimate it — diarrhea is quite complicated.
💬 Note from Doctor Luo: Any change in the body’s environment alters the intestinal environment and can produce diarrhea — sometimes lingering for months. Doctor Zhang Jingyue, a physician of the highest rank, once had diarrhea himself and needed a full year of constant adjusting and rewriting of his own formulas to recover — so no one should ever brag. Catch a chill, and the body temperature drops, blood and qi activity slows — diarrhea. Eat something unclean, and harmful bacteria multiply wildly, the body fights them, a heat pattern appears — diarrhea again. Hyperactive function, or exhaustion and weakness to the extreme, can both cause diarrhea. Same symptom, radically different causes — so you must always find out: what is actually happening inside? This is what we call treating the root of disease (zhi bing qiu ben).
And how do you determine it? The key lies in the principal contradiction.
💬 Note from Doctor Luo: Doctor Xue Lizhai’s method was to immediately decide whether the principal contradiction was upright deficiency or pathogen excess. When the pathogen was rampant, he too used clearing methods — remember the earlier case in which he added da huang (rhubarb) to Shao Yao Tang (Peony Decoction), one herb at one liang per dose, four doses with four liang of rhubarb in all, and cured the disease. So you cannot say Doctor Xue Lizhai only tonifies; when clearing is called for, he clears. But this official had hardly any pathogen — purely upright deficiency — so he tonified without hesitation and cured him in one dose, like a martial arts master ending the fight with a single strike of the sword.
Bonus: a small comparison with modern medicine
To close, Doctor Luo Dalun offers an interesting comparison: when Western medicine meets a child with diarrhea today, it often prescribes probiotics.
💬 Note from Doctor Luo: Probiotics go in and directly replenish the beneficial bacteria — that is essentially a form of “tonification.” See? Diarrhea treated with a tonifying method, and it works — the stools gradually firm up again. The thinking is the same as using Buzhong Yiqi Tang for qi-deficient diarrhea. The ancients already knew how to use Chinese herbs to adjust this environment — let the beneficial bacteria multiply, restrain the harmful ones, restore normal intestinal function, and then the diarrhea stops, and the bleeding stops with it.
Closing note: insufficient upright qi is the root of most illness
What is worth savoring again and again in this case is Doctor Xue Lizhai’s diagnostic skill.
💬 Note from Doctor Luo: Doctor Xue Lizhai left behind more than three thousand case records, and we are studying them slowly. He reminds us of a very important truth: most diseases appear only when your upright qi is insufficient and the body has gone wrong; pathogen excess usually arises on a foundation of upright deficiency — where pathogenic qi gathers, upright qi must be deficient (xie zhi suo cou, qi qi bi xu). And this applies not only to the intestines and the gut: when any organ, any part of the body goes wrong, the same list of causes is at play — qi deficiency and blood deficiency, yin deficiency and yang deficiency, phlegm-dampness and blood stasis, constrained liver qi. Resolve these clearly, and the body recovers on its own. That is the essence of regulating the body with Chinese medicine.
