Opening: this famous doctor’s first advice — “stay away from the beautiful women”

Today’s physician is the great Yuan-dynasty master Doctor Zhu Danxi. He had a distinctive way of practicing: he put enormous weight on the patient’s upright qi (zheng qi), and he was not afraid to say things people did not want to hear. This case concerns an elderly gentleman named Mr. Zhan — a government official with a very solid physical foundation. In Doctor Zhu’s own words, his “natural endowment was strong” (bing fu zhuang) — his inborn constitution was exceptional. Looking at his body and spirit, he was robust and sturdy, nothing like a frail scholar; his complexion was pale (se cang), which in that era’s terms was actually a sign of health. Mr. Zhan was nearly sixty — the age when a man ought to be settling into quiet retirement.

💬 Note from Doctor Luo: Doctor Zhu Danxi loved to describe a patient’s form and spirit — how sturdy the person was, what the complexion looked like, what the spirit was like. Writing down “strong natural endowment,” “walks very vigorously,” “pale healthy complexion” was his way of telling later generations: this patient’s foundation is good; the problem lies in acquired consumption, not in anything inborn.

Malaria in February: attacks every other day — the ancient “jia nue”

Mr. Zhan caught malaria in February — just after the New Year, when the weather was still cold. The attacks followed a strict pattern: every other day. Ancient texts called this every-other-day malaria “jia nue” (痎疟), and also “lao nue” (老疟) — the “old malaria” that drags on and on and never seems to end. Today we all know what malaria is: an infection caused by the Plasmodium parasite. It is still extremely common in Africa; in the past it raged through China too, and in ancient times it was one of the great scourges.

💬 Note from Doctor Luo: Malaria is one type of external-contraction disease (wai gan). What Doctor Zhu Danxi’s case actually demonstrates is the principle for treating all external-contraction diseases. He happens to talk about malaria, but the underlying approach applies to every one of them — which is why this case is especially worth listening to.

Doctor Zhu arrived and first looked at the man. Mr. Zhan was a high official who ate extremely well — rich, fragrant, greasy food day after day. Doctor Zhu was blunt: a person who eats this well has excess nutrition; food enters the body but is not fully digested, and some of it gets stored away — turning into phlegm-dampness, turning into garbage. Put such a man on an exam table today, and he would probably have all “three highs” (high blood pressure, high blood sugar, high blood lipids). So Doctor Zhu’s instructions were four characters: yuan se — stay far away from sensual indulgence — and shi dan — eat plainly. Mr. Zhan was an official with wives and concubines: at nearly sixty, heavy indulgence would wound the kidney qi and kidney essence — that is internal consumption. And eat plainly. Adjust the lifestyle first, then use medicine, allowing about a month, because the body had already fallen into disorder — a slow process. And at the end, the patient should break into a big sweat — the evil qi leaves through the sweat, the qi and blood flow freely, and the illness is cured.

The setback: the patient refused the advice and switched to a “cured in days” doctor

Doctor Zhu’s words were perfectly reasonable — but Mr. Zhan did not want to hear them. You want me, an important official, to keep away from beautiful women, eat plainly, and take a whole month to get better? The great man was displeased. Another physician chimed in: this illness is easy — I’ll have you cured in a few days! He used “jie nue yao” — the “malaria-cutting” herbs, strong, fierce medicines meant to chop the malaria attack off short.

💬 Note from Doctor Luo: Jie nue yao were the potent herbs used specifically to intercept a malaria attack. Here’s a classic trap in reading ancient books: the old text’s punctuation was often added by later editors, and it was sometimes wrong. The phrase “以白术，粥和丸” (take bai zhu, mix with porridge into pills) was once mis-punctuated as “白猪粥和丸,” making readers think of “white-pig porridge pills.” Not at all — it means: grind bai zhu (atractylodes) into powder, mix it with cooked porridge, and form it into pills; the porridge is only the binder. Different punctuation, completely different meaning — always read carefully.

Mr. Zhan thought this sounded wonderful, so he took the malaria-cutting herbs for three to five doses. And hey — the illness seemed to retreat; no more attacks. But about ten days later it came back. He took the medicine again; it improved; ten days later it relapsed again… and so it dragged on, never really healing. The case record says it “lingered until winter” (chan mian zhi dong) — an illness that began in February stretched all the way to the following winter, nearly a full year! By then Mr. Zhan was worn to a shadow by the disease and came back to beg Doctor Zhu for help.

A second look: the evil qi is weak now — but so is the upright qi

This time Doctor Zhu reassessed. The earlier physician had spent a year driving out evil and resolving phlegm with strong herbs — the phlegm-dampness was, in fact, mostly cleared. The early treatment cannot be called a complete failure. But the problem now was different: the upright qi was insufficient and the spleen-stomach had been injured. On top of that, the weather was cold — even getting a sweat out was difficult, so the evil qi had no way out. Upright qi too weak to produce sweat; weather too cold to sweat anyway. What to do?

Doctor Zhu’s decision: support the upright qi.

The prescription: one herb, two jin of pills, straight to the point

The formula Doctor Zhu gave is astonishingly simple — bai zhu (atractylodes), and nothing else. He had the herb ground into powder, mixed with cooked porridge, and formed into pills — two jin (about one kilogram) in total. How to take them? On an empty stomach before meals, one to two hundred pills at a time, washed down with warm water.

💬 Note from Doctor Luo: One to two hundred pills is no small dose! In those days pills were made the size of wutong (Chinese parasol) seeds — like today’s small water pills — but one to two hundred of them still amounts to several dozen grams. These days we take pills gently, slowly. But when you are genuinely treating an illness, you need not be bound by “one or two pills”; when necessary the dose can be adjusted. Doctor Zhu Danxi dared to give a patient tens of grams at a single sitting.

Why take them before meals, when hungry? Because when you are hungry, the spleen and stomach are calling for nourishment — and at the very moment nourishment is needed, you supply it, directly tonifying the spleen. Bai zhu tonifies the spleen, drains dampness, and supports the upright qi. Meanwhile, the diet was plain congee — no rich food for now — so the spleen and stomach could recover. Doctor Zhu said: finish the two jin of pills, and you should break into a great sweat and be healed.

And that is exactly what happened. When the pills were finished, the patient broke into a big sweat — and the illness was gone.

💬 Note from Doctor Luo: Why the sweat? Because the upright qi had recovered, the spleen and stomach were full again, the qi and blood moved normally, and the body pushed the last of the residual evil qi out. Sweating is simply a manifestation of normal qi-blood circulation. The beauty of this case: the evil-dispelling medicines had already been used more than enough; the phlegm was mostly resolved; what remained was only deficiency of upright qi. Doctor Zhu topped the upright qi up, and the body expelled the evil all by itself. One herb cured an illness that had dragged on for a year — when a true master has identified the root cause, the formula becomes incredibly simple, even down to a single herb, straight to the point.

Why tonify only? Doctor Zhu saw through the disease of his era

Why did Doctor Zhu Danxi value upright qi so highly? Because he saw that the people of his own time were completely different from those of Doctor Li Dongyuan’s era. Li Dongyuan lived in the Jin-Yuan period, when people could not even get food and were fleeing famines everywhere. By Doctor Zhu’s day life had improved a little, and people began to think about enjoying themselves. What Doctor Zhu observed over the years: among people under fifty, very few had sufficient upright qi — most were weak and timid constitutions; and indulgence in desire was ten times what it had been before.

What were the people of that time like? Doctor Zhu described them: when the weather got even slightly hot, they retreated to cool terraces and waterside pavilions and shady groves, waving fans, or bathed in cold spring pools — such people hardly sweat at all. When sweat cannot come out, it stagnates inside and turns into phlegm-dampness. Add reckless eating — dining out every day, rich and greasy food; excessive labor — enormous workloads, staying up late working; plus indulgence in sex, which wounds the kidney essence. The stomach qi is badly damaged, and illness arises — for such a person, it is not just malaria: any external evil finds it easy to enter.

💬 Note from Doctor Luo: Doctor Zhu observed life with remarkable care — what he described matches today almost exactly. Think of modern young people: in summer we live in air conditioning — precisely the season when we sweat least; we eat well — every day hunting down the best-reviewed restaurant and eating hard; we overwork — staying at the office until eight, nine, ten at night. I once took a taxi in Shenzhen and the driver told me that huge numbers of young people hail cabs home at three or four in the morning. And add indulgence that wounds the kidney essence. The four causes Doctor Zhu listed — reckless eating, overwork, indulgence, and not sweating — line up with modern life perfectly.

So for diseases of this kind, Doctor Zhu’s killer moves were ren shen (ginseng) and bai zhu (atractylodes) — tonifying qi and strengthening the spleen-stomach; these are the two herbs he used most often in his case records. He paired them with chen pi (tangerine peel) to move the qi — tonifying without stagnation, smoothing the qi flow — and with shao yao (peony) to restrain yin and nourish the blood, building up both yin and yang, qi and blood. On top of that he added channel herbs (ben jing yao) — for whatever channel the disease sat in, he used the herb that disperses evil from that channel. In this way the qi and blood circulate freely, the body naturally works up a light sweat, the upright qi recovers, and the evil qi is dissolved. But while treating, one must also: eat plainly — do not add more phlegm-dampness to the body; reduce comings and goings — lighten the workload, do not run yourself ragged chasing promotion and wealth; avoid wind and cold, seek warmth — do not go to places of strong wind and severe cold; and be moderate in sex. Nurture yourself carefully, and the body will surely recover.

The master principle for external-contraction illness: check the upright qi first

Doctor Zhu’s case is about malaria, but what it actually teaches is the master principle for treating all external-contraction diseases: first look at whether the person’s upright qi is sufficient, how much has been consumed, and how heavy the phlegm-dampness inside is. If the internal problems are substantial, you must genuinely invest effort in regulating the internal environment — once the internal environment is well adjusted, add just a little evil-clearing medicine and the illness resolves. If you ignore the internal environment and simply keep driving out evil, again and again, you end up wounding the upright qi — and the illness drags on: it looks cured for the moment, then flares up again a while later.

💬 Note from Doctor Luo: Many children today catch colds every few days — two or three times a month. Why? Because previous treatments paid too much attention to clearing external evil — every cough treatment was “diffuse the lung and scatter cold,” “diffuse the lung and stop the cough,” sometimes with herbs too fierce, wounding the upright qi. The correct approach is to recognize the deficient upright qi, tonify the spleen and stomach, add just a tiny bit of evil-clearing medicine — and the child gradually stops catching colds. Always see the “person” behind the “disease” — insufficiency of upright qi is the root of illness. This is what Chinese medicine means by “treating the root” (zhi bing qiu ben). In treating Mr. Zhan, others had already used plenty of evil-dispelling herbs; Doctor Zhu simply tonified the upright qi — and once it was sufficient, the body cleared the evil by itself. And after recovery, the patient’s spleen and stomach were stronger than before, his body in better shape overall — that is the philosophy worth learning.

What to take away

• One herb, straight to the root. When a true master sees the pattern clearly, the formula can be as simple as a single herb. For a malaria that had dragged on nearly a year, Doctor Zhu used only bai zhu (atractylodes), made into two jin of pills — and the patient broke into a great sweat and recovered.
• First check the upright qi. In any external-contraction illness, ask first: is this person’s upright qi sufficient? If the internal environment (spleen-stomach, phlegm-dampness) is disordered, fix that first; then a little evil-clearing medicine is enough. Endlessly attacking the evil while the upright qi keeps failing only makes the illness linger.
• Ancient lifestyle advice that still applies today. Plain food, less overwork, avoid cold wind, moderate indulgence, and — especially in summer — do not live entirely in air conditioning; let yourself sweat. Doctor Zhu’s four observed causes of disease — reckless eating, overwork, indulgence, and not sweating — match modern life almost one for one.
• Tonifying is not “doing nothing.” When the upright qi is restored, the body expels the residual evil itself — sweating is the sign that qi and blood are moving normally again.
