Opening: the real secret of this case is not malaria
Today’s story is another of Doctor Zhu Danxi’s consultations, and the illness is again malaria — what ordinary people call “the shakes” or “the ague.” But Doctor Luo Dalun wants to set the stage honestly: this case is not really about malaria at all. It uses malaria as a doorway into a deeper lesson — every body is different, and when you treat illness you must always take each person’s uniqueness into account.
💬 Note from Doctor Luo: The same disease — this person treated one way, that person another way. What makes the difference? The “person” is different. Today’s patient carried this principle to its extreme.
Who was the patient? A woman whose period had not come for three months
The original text opens with six characters: “yi fu ren bing nue” — a woman fell ill with malaria. Her malaria had a distinctive rhythm — jian liang ri yi fa, it attacked every other day. Her appetite was also poor: yin shi jue shao — she ate very little, almost nothing. And then came the truly strange detail: “jing mai bu xing” — her menstrual flow had stopped. It had been three months since her last period.
💬 Note from Doctor Luo: Think about it — why would her period stop for three months? The interesting part of this case is exactly that “stopped period.” That is where the story turns.
The most frightening moment: the pulse in both hands could not be felt at all
When Doctor Zhu Danxi came to see her and felt her pulse — liang shou ju wu — there was no pulse in either hand. He could not feel it.
Now, readers, if this had been an ordinary physician, alarm bells would have gone off instantly: three months with no period, and now no pulse? This must be extreme deficiency! The qi and blood have drained to their last drop; the woman is at death’s door — rush in and build her up with heavy tonics!
💬 Note from Doctor Luo: A pulse you can’t even feel certainly looks dangerous. But Doctor Zhu Danxi did not jump to conclusions. He did something most physicians would never do — he took a careful look at the person.
What did Doctor Zhu Danxi think? The pivotal stroke of the whole case: look at the person
Doctor Zhu Danxi observed this woman and noticed that she was dressed and made up as usual, and her speech and gait showed no exhaustion — “shu zhuang ru chang, yan yu xing bu bing wu juan dai.” She looked and moved exactly as she always did. There was none of the collapse, none of the drained, listless appearance you would expect if her qi and blood were truly spent.
That was telling. If she were truly and deeply deficient, she should have been listless and prostrate, barely able to move. But this patient moved and acted normally — which meant the “missing pulse” had to have another explanation.
💬 Note from Doctor Luo: This is the art of inspection (wang zhen). Doctor Zhu Danxi excelled at miscellaneous diseases, and in one glance he could see: this woman does not look that deficient. So you cannot conclude from the pulse alone — you must combine inspection with the whole picture before deciding.
The truth comes out: not blood deficiency — phlegm had blocked the channels
Doctor Zhu Danxi thought it through and understood: the period had stopped not because the blood was depleted and gone, but because phlegm was stuck in the way — in his words, “nai tan suo ai er bu xing ye” — it was obstructed by phlegm and could not move. Her body was heavy with phlegm-dampness; once she fell ill, the phlegm-dampness erupted and blocked the channels.
And the undetectable pulse was not the “pulse extinction” of blood exhaustion either. Rather, accumulated phlegm generated heat; the phlegm joined with the external pathogen and clumped into masses that stuffed up the channels — so of course, when you feel for the pulse, you find nothing.
💬 Note from Doctor Luo: So this illness must not be treated as deficiency at all — it must be treated as excess heat; it is an excess pattern. If you looked at her tongue, you would expect a red tongue body with a thick, greasy coating, tinged yellow at the center — that is what heavy phlegm accumulation looks like.
The prescription explained: Sanhua Shenyou Wan, a fierce purgative that drains water downward
The formula Doctor Zhu Danxi wrote was called Sanhua Shenyou Wan (Three-Flower Spirit-Assist Pill). What kind of medicine is this? It is a water-draining, purgative formula — it contains da ji (Peking spurge root), qian niu zi (morning glory seed), da huang (rhubarb) and other herbs that drain outward — specifically to purge water and expel phlegm. It is extremely powerful.
💬 Note from Doctor Luo: When people talk about Doctor Zhu Danxi dissolving phlegm, they usually think of gentle formulas like Er Chen Tang (Two Aged Ingredients Decoction). But with this patient, he did not hold back at all — he went straight to purging. Why? Because he could see that this woman had been eating too well, that there was heavy accumulation inside her, so he drained and purged the phlegm directly. It is an aggressive strategy — but he made it into pills for her to take, dissolving a little each day, day by day, slowly.
The course of treatment: appetite opened in ten days, all six pulses returned in a month
After ten days of the pills, the woman’s appetite gradually returned and she could eat again. Why? Because the channels had been blocked; now that the purging had opened them, the appetite naturally recovered. And the pulse began to reappear.
After one month, liu mai ju chu — all six pulses of both hands (cun, guan, chi on each side) came out again, though with a slight wiry (xian) quality. At this point the malaria still had not resolved.
💬 Note from Doctor Luo: Pay attention — here Doctor Zhu Danxi made a bold decision: stop the medicine. He did not say “take a few more rounds to root out the disease.” Instead he told her to stop taking anything. Why?
The art of stopping: spring deepening, warmth rising — let the body heal itself
Doctor Zhu Danxi explained: the appetite has recovered, digestion is normal again, the body is gradually absorbing nutrients, and the upright qi will grow stronger and stronger — wei qi ju quan, the stomach qi is complete. And by now, spring was deepening — the season was turning from spring into summer, the weather warming day by day. Jing xue zi wang — the menstrual blood will flourish on its own; and this illness, too, will certainly recover by itself.
So, there is no need for more medicine. What comes next is dan zi wei, jie yin shi — eat plainly, eat moderately. Stop rich and heavy foods. This woman must have eaten extremely well — how else would a lady’s body carry such heavy phlegm and food stagnation? So Doctor Zhu Danxi stressed it especially: light food, controlled portions, no eating whatever you fancy.
💬 Note from Doctor Luo: Why don’t the other cases teach this, and why did this one have to? Because this patient could not control herself — she would definitely reach for the good food again. So Doctor Zhu Danxi gave her dietary guidance and lifestyle guidance targeted specifically at her. This was personalized treatment aimed at this particular patient.
The woman followed his instructions, and half a month later the malaria was cured and her period returned — the qi and blood had flowed freely again on their own.
The interpreter’s note: Doctor Zhu Danxi’s wisdom of “heaven’s timing”
Doctor Luo Dalun says this case shows more clearly than almost any other how deeply Doctor Zhu Danxi understood nature. He could already see that spring was turning toward summer — the qi and blood would inevitably flourish and circulate; as the body grows warmer, the qi and blood begin to move. So there was no need for more medicine — let the body restore itself.
💬 Note from Doctor Luo: Going along with the seasonal movements of qi is a profound skill. Take a child’s lingering cough after a cold: if the cold was caught in late autumn or winter, the cough will grow worse, and you must put real force into scattering cold and opening the lungs. But if the cold was caught in spring, the weather is warming, the yang qi is rising — the body can clear that cough by itself; you don’t need heavy medicine, just a little to support the upright qi and a little to push outward, and it resolves as the weather warms. Parents who don’t understand this often pile on the medication and overdo it — and actually harm the child. In some cases you could even use no medicine at all: a cough from cold pathogen, once summer arrives and the yang qi flourishes — some sunshine, a good sweat — the external pathogen is released on its own.
A bonus tangent: Qian Yi’s “medication rhythm”
Qian Yi, the founding father of Chinese pediatric medicine, was equally attentive to this kind of rhythm when treating children. Around the start of autumn and through the changing seasons, he would adjust whether warming or cooling herbs dominated — the proportions were constantly calibrated — because each season shifts the qi movements, and the proportions of the prescription must shift with them.
💬 Note from Doctor Luo: Doctor Zhu Danxi worked the same way. He saw that spring was deepening toward summer, the spleen and stomach had recovered — so he stopped the medicine. If he had kept on purging and dissolving phlegm, the treatment would have suppressed the body’s rising, generative qi. So he stopped and let the body heal itself; you simply had to stop adding more phlegm to the account — and that is exactly what “eat plainly, eat moderately” means.
A warning: strange diseases arise from phlegm — and modern people especially should take care
What else can we learn from this case? Doctor Luo Dalun gives a special reminder: accumulated phlegm, if it enters and blocks the channels, causes channel obstruction and all kinds of strange illnesses — the old saying of Chinese medicine, “guai bing duo tan” — strange diseases often arise from phlegm.
In modern society people eat too well, too rich and heavy, and phlegm-dampness is especially heavy — and it genuinely causes all sorts of problems. Many cardiovascular and cerebrovascular diseases, for example, are tied to high blood lipids — and in Chinese medicine terms, that is closely related to phlegm blocking the channels.
💡 Note from Doctor Luo: These days many women genuinely have a very weak pulse — sometimes you truly cannot feel it. Does that always mean depleted qi and blood? Put a question mark on that. Some women have ice-cold hands and feet in winter, and everyone assumes blood deficiency — possibly. But it could also be blood stasis, or it could be very heavy phlegm-dampness making the qi and blood circulation sluggish — when the weather turns cold, phlegm congeals harder, blocks the channels harder, and the hands and feet go cold.
So how do you recognize heavy phlegm? Look at the tongue — the coating is generally thick. The body tends toward overweight (though thin people can have it too — this is a rough guide). And the body often carries various nodules and phlegm kernels (tan he) — press here and there and you find a lump. Conditions like lipomas and fibroids are extremely common now; many people have them precisely because their internal phlegm-dampness is very heavy.
💬 Note from Doctor Luo: Doctor Zhu Danxi wrote this as a special case — this woman, because she caught malaria, had the problem erupt all at once: the period vanished, the pulse vanished. What he wants to tell us is that phlegm-dampness really does obstruct the channels and produce all kinds of strange illnesses. Especially all you “foodie” friends — lovers of fine eating — should follow Doctor Zhu Danxi’s advice and eat plainly and moderately. Otherwise, day after day of rich, heavy food, the phlegm grows heavier, and in the end something serious really can happen.
