The opening: Doctor Xue Lizhai named the cause in one sentence
Today we continue with the case stories of Doctor Xue Lizhai (薛立斋), the great Ming dynasty physician. This case opens in an unusual way — in his very first line, Doctor Xue named the cause outright. No hedging, no roundabout.
💬 Note from Doctor Luo: People are always unsure how to tell an external invasion (外感) from an internal injury (内伤). Doctor Xue Lizhai simply tells you: stop going around in circles — this is internal injury! Why was he so sure? Because the very first line of the case record states the cause: irregular diet and overwork (饮食劳倦).
Who was the patient? Four words that describe half the modern world
The patient was a man, and the cause of his illness is written plainly: irregular diet and overwork.
What does that mean? Diet — eating badly, with poor habits. Overwork — burning yourself out, working too hard, resting too little. In plain words: it is a lifestyle problem.
💬 Note from Doctor Luo: Bad lifestyle habits are the easiest way to create internal injury: weakened spleen and stomach, insufficient kidney qi, excessive consumption… If people really solved those four words — “irregular diet and overwork” — I estimate internal-injury disease would drop by more than half. So don’t dismiss this simple-sounding cause; it’s actually a big deal.
How sick was he? Chills and fever — and a numb right hand
After the diet-and-overwork damage, this man developed chills and fever — cold one moment, hot the next. His body’s thermostat had gone wrong.
Why? After internal injury, qi and blood are insufficient and their circulation is disrupted; the body’s “temperature control system” fails. People with deficient qi often feel cold — when others wear one padded coat, they need two or three. When the deficiency deepens, the inside feels cold while the outside burns with fever.
Besides the chills and fever, he had one distinctive symptom — numbness in the right hand.
💬 Note from Doctor Luo: Note: the right hand, not both hands. That detail is the most brilliant part of this whole case — it’s the clue Doctor Xue Lizhai cracked the case with.
How did the earlier doctors treat him? Clearing heat and toxins — and making him worse
Looking at the numb right hand, the earlier doctors concluded: there must be some poison trying to come out — either an abscess forming or heat toxin brewing. So they applied ointments and gave decoctions, all cold, toxin-clearing medicines — the “clear heat and resolve toxin” (清热解毒) style.
The result? He only got worse. His body swelled; he felt a heavy, sinking sensation — as if his qi were dropping downward; his face turned sallow — that withered, lifeless yellow; and his limbs grew weary — no energy all day.
💬 Note from Doctor Luo: Every one of these symptoms is a signal. The sallow face means great injury to spleen earth. The swelling means the spleen qi is insufficient and dampness is excessive. The heavy, sinking feeling means qi deficiency with qi collapse. The weary limbs mean severe deficiency of spleen qi. And then the pulse — the six pulses floating and large, but empty when pressed: a floating, large pulse that loses its strength under the finger is a deficient pulse! That “large” is an illusion — not strong righteous qi, but the body making a last-ditch struggle.
Doctor Xue’s thinking: ask about the job — and the truth comes out
Doctor Xue Lizhai’s diagnosis: deficiency of spleen and stomach qi — the spleen qi was badly depleted. But one question remained: if this is qi deficiency, why is it specifically the right hand that is numb?
He was extremely thorough. He asked the patient: what do you do for a living?
The answer — he was a silversmith!
💬 Note from Doctor Luo: What does a silversmith do? Say you have a ring you no longer wear and want turned into a necklace. He has to heat the silver until it melts, then dip it in cold water to cool and set it, then heat it again, dip it again… over and over. When the hand is scorching hot, the pores open and the channels are free; the moment it goes into cold water, the channels are suddenly frozen shut by the cold — this is what Chinese medicine calls “cold congealing the tunnel” (寒凝隧道): the channels seized up by cold. His righteous qi was already insufficient — the spleen governs the four limbs, and qi and blood were barely reaching them — and on top of that, this hot-hand-into-cold-water routine all day long chilled the right hand. So the illness was tied directly to his occupation!
The prescription: two routes — drink it and soak it
Once the root was found, Doctor Xue Lizhai treated on two fronts:
First route: Buzhong Yiqi Tang (Tonify the Middle and Augment Qi Decoction) by mouth — to tonify the spleen and stomach and lift the qi upward. Why? Because of the heavy, sinking symptom: his qi mechanism was beginning to collapse downward.
💬 Note from Doctor Luo: Qi sinking is one manifestation of qi deficiency: when qi deficiency reaches a certain point, it can no longer hold the organs up, and the qi sags down. Buzhong Yiqi Tang tonifies the spleen and stomach and raises the qi mechanism — exactly on target. That’s the root treatment.
Second route: a warm herbal decoction to soak the hand — warming herbs simmered into a soup to soak that numb right hand.
💬 Note from Doctor Luo: Which herbs? Doctor Xue didn’t list them, but the thinking is clear: warming herbs like gan jiang (dried ginger), chuan jiao (Sichuan pepper) and ai ye (mugwort leaf) would all do. Internally, tonify the righteous qi; externally, soak the hand with warming herbs to open the local channels and drive out the cold — internal and external treatment together. That is exactly the hallmark of Doctor Xue Lizhai’s approach to this illness!
One comma in the classical text — Doctor Luo explains it for you
The original case record reads: “Buzhong Yiqi Tang, and warming herbs simmered into a decoction for soaking the hand, and he recovered.” Many people read it as: boil the Buzhong Yiqi Tang together with the warming herbs and use the whole thing to soak the hand.
💬 Note from Doctor Luo: No! There should be a comma in there: Buzhong Yiqi Tang (taken by mouth), and warming herbs simmered into a decoction (for soaking the hand). Why? Because Buzhong Yiqi Tang acts on the spleen and stomach — if you soak your hand in it, you’re going the long way around. The spleen and stomach absorb the decoction directly when you drink it; what good would soaking do? So the Buzhong Yiqi Tang was drunk, and only the warming herbs were used for soaking. The illness was local, and the local injury was unmistakable — treating it locally with a soak is precisely Chinese medicine’s external treatment method (外治法).
Three lessons from this case
Doctor Luo sums up three points especially worth learning:
Lesson one: the indications for Buzhong Yiqi Tang. Always feeling chills and fever (hot and cold in turns), swelling after cooling herbs were used, sallow complexion, weary limbs — these symptoms are all manifestations of qi deficiency and all fall within the indications of Buzhong Yiqi Tang. Once you read through Doctor Xue Lizhai’s cases, the indications of this classic formula become clear.
Lesson two: examine carefully — always ask how the illness began. Many illnesses are caught by accident, right out of work and daily life — tied to one’s occupation. If you don’t ask carefully, you would never guess.
💬 Note from Doctor Luo: When truly analyzing a case, you must ask: what happened right before you got sick? For example, someone went traveling, waded through a mountain stream, and came home with a sore heel; or the child came home and spiked a high fever — the cause is perfectly clear: local cold invasion! Without asking, you really cannot guess such a thing; once you ask, the puzzle solves itself. A good doctor should be like Sherlock Holmes — even a bit of a psychologist. Walk through the door, sweep the room once, and you can see the relationships in the family and who tends to get which illness. That’s inference on top of a “big data” of experience — something beyond the medical textbook.
Lesson three: the wonderful use of external treatment. If the pathogen came from the outside, and you can drive it out with herbs applied locally — of course that’s the best. Internal causes are adjusted by internal medicine; external causes are treated externally — combining internal and external treatment is a particularly good way of thinking about illness.
A bonus story: the “master” at a Shenzhen dinner table
Doctor Luo once told a true story: at a dinner in Shenzhen, a Western-trained doctor sat at the table, looked around the room, and began naming the traits of everyone present — even each person’s spouse: whose partner loved to lecture, who might have breast problems. He was startlingly accurate, and the whole table was stunned.
💬 Note from Doctor Luo: I was sitting right next to him and asked: “Brother, did you practice qigong or something?” He said no — it’s just from seeing patients: a hundred patients a day for decades. One glance and he could tell what disease a person had and what the family dynamics were. He was a Western doctor, but he was a good doctor: he saw things beyond the medical data. Doctor Xue Lizhai was the same kind of master — one question about occupation, and the illness was linked to the work. So a good doctor of Chinese medicine must be someone who understands human nature and reads the small signs (见微知著).
Closing: a short case, worth savoring
Today’s case is very short, but it’s fascinating: chills and fever, a numb right hand — it looks complicated, but the cause was hiding in four words, “irregular diet and overwork,” and in one occupation: silversmith. Treating illness is like solving a case. Once the cause is clear, the illness resolves itself.
💬 Note from Doctor Luo: Watching a master like Doctor Xue Lizhai work is basically a pleasure, and it inspires a lot of my own thinking. Thank you all for listening — tomorrow we’ll continue with more of Doctor Xue Lizhai’s case stories.
