Vomiting Clear Water All Day? Doctor Miao Xiyong’s Case of Fluid Retention — One Dose Stopped It, Two Doses Cured
Patient search terms: vomiting all day / vomiting clear water / vomiting that won’t stop / vomiting by the basin and bucketful / no appetite
Opening: this famous doctor was like a knight-errant — he lived wherever he went
In the Ming dynasty there lived a famous physician named Doctor Miao Xiyong, a native of Changshu in Jiangsu, and a close friend of the Donglin literati. He had a wonderfully lovable personality — something of a knight-errant about him. He practiced medicine as he roamed, with no fixed home: he stayed here one day, there the next, renting houses wherever he went, and gave himself the elegant nickname “the Lodger” (yu gong). Wherever he went, he treated whoever was sick — and the results were astonishingly good.
💬 Note from Doctor Luo: A small digression — I record one of these short talks on Ximalaya every day and have done so for years. The other day a friend told me I now have 1.99 million followers — Teacher Guo Degang only has 1.5 million. I never usually look at these numbers, but it did move me: when you sincerely work for people, people sincerely support you. Thank you all. Now, back to Doctor Miao Xiyong’s story.
Who was the patient: a housewife worn down by work and pent-up frustration
Today’s patient was the wife of Ge Wenxue, a scholar from Danyang. The case record says it plainly: “Because of housework and labor at home, she fell ill with fluid retention” (yin zheng). Note — the phrase “zuo jia” here doesn’t mean “becoming a writer”; it means she managed the household, worked in the fields, and was exhausted. And the phrase that follows hints at something more — she was also nursing some unhappiness at home, a certain suppressed frustration.
Overwork plus suppressed emotion — and illness arrived.
💬 Note from Doctor Luo: Remember this combination: labor injures spleen qi, and frustration injures liver qi. When liver qi knots up, the wood element bullies the spleen, and the spleen-stomach lose their ability to transform and transport dampness. This is the seed of the whole disease mechanism to come.
How sick was she: vomiting that shook heaven and earth — and all of it clear water
The most terrifying part of her illness was the vomiting. Whenever an attack came on, she vomited without stopping — and with terrible violence, as if she wanted to bring up even the contents of her intestines. Strangest of all, she wasn’t bringing up food — it was all clear water, water-like fluid.
And the volume was astonishing: counted in basins and buckets. One attack filled a large basin, a whole bucket. And it continued day and night, without pause. On top of that she had no appetite — she simply could not get food down. Think about it: she already couldn’t eat, and everything she brought up was water. This was truly serious.
What the previous doctor did: the logic looked right — and the patient only got worse
The family took her to Jintan to see a doctor. The Jintan physician looked and thought: spleen deficiency, heavy dampness. The logic sounded quite reasonable — strengthen the spleen, move the qi, resolve the depression, clear the phlegm. All the appropriate medicines were used: spleen-strengthening, qi-moving, liver-soothing, phlegm-resolving.
The result? The illness grew steadily worse. Tou zhi yu ju — the more they treated, the worse it became. Ge Wenxue was at his wit’s end. There seemed to be no cure for this disease anywhere.
💬 Note from Doctor Luo: Now wait — was the doctor’s thinking wrong? Strengthening the spleen and moving the qi is not wrong at all! So why did the patient get worse? Because the treatment didn’t hit the mark — the force and the direction were each off by a layer. The true master is different precisely because he can see in one glance where the disease lives and which medicine will seize it at once.
The turning point: Doctor Miao Xiyong arrives, introduced by Zhuang Lianzhi
As luck would have it, Doctor Miao Xiyong had just come to the area from Huzhou. Being the perpetual “Lodger,” this time he was lodging next door to a local gentleman named Zhuang Lianzhi.
And Zhuang Lianzhi was no ordinary man — he was Doctor Miao’s number-one fan. Doctor Miao’s celebrated Xian Xing Zhai Yi Xue Guang Bi Ji (Notes from the Studio of Fresh Awakening on Broad Medical Learning) was transcribed and published thanks to Zhuang Lianzhi and his circle. Zhuang himself had once fallen ill — poisoned by croton-bean juice (ba dou) — and Doctor Miao had cured him, so his faith in the doctor was absolute.
Zhuang Lianzhi and Ge Wenxue were in-laws, related by marriage. When he heard that the Ge family’s lady was gravely ill, Zhuang said to Doctor Miao: “This relative of mine is very sick, and ordinary physicians can’t help. Would you trouble yourself to see her?”
One look, one verdict: this is fluid retention, beyond doubt
Doctor Miao arrived at the Ge household, examined the tongue, felt the pulse — and pronounced it in a single breath: this is “yin” — fluid retention. No doubt about it. Zhi wei yin wu yi.
💬 Note from Doctor Luo: And here comes the most important knowledge of today’s talk — what exactly is “yin” (fluid)? Chinese medicine speaks of tan yin, “phlegm and fluid,” but phlegm and fluid are two different things: tan (phlegm) is the thick, sticky fluid of the body; yin (fluid) is the thin, watery, freely flowing fluid. These days we talk a lot about “water-dampness,” and everyone understands “heavy dampness.” But the ancients divided abnormal fluids far more finely — dampness, water, fluid, phlegm — layer by layer, each with its own name.
Dampness, water, fluid, phlegm: each layer thicker than the last
Right here Doctor Miao Xiyong lays out the whole pathological progression of body fluids with perfect clarity:
Dampness (shi) is a diffuse state, like vapor spreading everywhere; where dampness gathers and comes to rest, it becomes water (shui); when water keeps concentrating and condensing, it becomes fluid (yin) — the thin, slightly sticky kind, almost transparent, a bit like raw egg white; and when fluid condenses further, it becomes phlegm (tan) — the very thick, sticky kind that plugs things up.
💬 Note from Doctor Luo: So you see, from dampness to water to fluid to phlegm, it’s a step-by-step “concentration” process. What this lady was bringing up was clear water — so it was fluid (yin), not phlegm. The fluid was sitting in her stomach, and whenever an attack came on, it all came gushing out. Diagnosis — settled with a single stroke.
Bonus: how finely the ancients classified “fluid”
Doctor Miao Xiyong says “there are five kinds of fluid,” and the phrase has deep roots. The medical sage Zhang Zhongjing, in the Jingui Yaolue (Essential Prescriptions of the Golden Cabinet), divides fluid into four kinds:
- Tan yin (phlegm-fluid): the patient was usually plump but has now grown thin; water runs through the intestines, and the belly gurgles and sloshes audibly — this is tan yin;
- Xuan yin (suspended fluid): after drinking water, the fluid lodges between the ribs, and coughing or spitting brings pain in both flanks — this is xuan yin;
- Yi yin (spilling fluid): the fluid spreads to the four limbs; the person should sweat but cannot — dang han chu er bu han chu — with body aches, heaviness and swelling — this is yi yin;
- Zhi yin (supporting fluid): coughing and panting while propped up, unable to lie flat, gasping for breath, miserable even lying down, the whole body swollen — this is zhi yin.
Doctor Miao Xiyong’s “five kinds” is another way of slicing it: fluid stopped below the heart is liu yin (retained fluid); fluid stopped beneath both ribs is pi yin (side fluid); fluid in the stomach is dan yin (bland fluid); fluid above the diaphragm among the five organs is yi yin (spilling fluid); fluid in the intestines that sloshes audibly at the slightest movement is liu yin (flowing fluid).
💬 Note from Doctor Luo: Look how finely the Chinese ancients studied this! Every place water can stop has its own name, its own treatment, even its own formulas — there were general-purpose pills like Wu Yin Wan (Five-Fluid Pill) and Da Wu Yin Wan (Great Five-Fluid Pill). The ancients also said “a hundred diseases are often caused by phlegm” — to have studied water, fluid, phlegm and dampness to this depth is real precision. Modern practice is sometimes not so fine-grained anymore, but when you truly encounter a body that always holds water, the ancients’ classifications still work.
Where did it come from: the spleen is the core — lung, spleen and kidney together govern water
Where does fluid come from? Doctor Miao Xiyong’s answer is consistent: insufficient upright qi (zheng qi) is the core. When upright qi is insufficient, and external pathogens and dampness interfere, the transformation and transport of fluids breaks down.
Within that, spleen-stomach deficiency is the very heart of it — the spleen belongs to earth, and earth controls water; when spleen earth is weak it can no longer manage the water. Kidney qi deficiency is also critical, because the yang of the spleen and stomach comes from kidney yang. And the lung regulates water too — the lung governs the waterways (tong tiao shui dao). So of all the organs, the lung, spleen and kidney have the closest relationship with fluid retention.
Getting more specific about causes, Doctor Miao Xiyong sums up three great sources:
- From drinking alcohol: people who love wine gulp it down, get drunk and thirsty, then drink large amounts of water. If upright qi is strong, fine; if not, they can no longer control the water and dampness. Wine is hot in nature, so this produces damp-heat;
- From drinking cold beverages: gulping ice-cold water and chilled drinks in hot weather — the ancients had chilled wine too. Cold and cool fluids stay in the body — this is cold-damp;
- From bottled-up emotion: illness from depression — liver qi knots, the wood element runs rampant and attacks spleen earth, the spleen-stomach break down and lose the power to transform dampness.
💬 Note from Doctor Luo: So the grand strategy for treating fluid retention emerges — descend the qi, dry the dampness, disperse the depression, strengthen the spleen, move the qi. The prescription Doctor Miao Xiyong writes next follows these five characters to the letter, not one missing.
The prescription, unpacked: ban xia leads, qi moves and dampness drains all the way down, ginseng holds the center
Doctor Miao Xiyong wrote a formula specially for fluid retention, and both the herbs and the logic are exquisitely arranged:
Ban xia (pinellia), processed in ginger juice and alum until soaked through, 4 liang — the lead herb. Ban xia descends qi and resolves phlegm; ginger-processed ban xia is exceptionally strong at directing rebellious qi downward and stopping vomiting, and at warming the middle burner to stop vomiting. This patient’s main problem was vomiting with qi rushing upward, so ginger-processed ban xia was exactly right.
💬 Note from Doctor Luo: Let me pause on the lore of ban xia — many friends have asked me to go deeper on this. When you buy ban xia at a pharmacy, they ask: qing ban xia, fa ban xia, or which one? — Ban xia comes in several processed forms. Raw ban xia (sheng ban xia) is toxic; taken orally it must be prescribed and prepared by a physician — never chew it casually yourself. If you pick wild ban xia and taste it, within a minute or two your throat will close up and you won’t be able to breathe. To control the toxicity it must be processed: boiled through with fresh ginger and alum, then sliced thin — that is jiang ban xia (ginger-processed pinellia), strongest at warming the middle and stopping vomiting; soaked in licorice and lime water — that is fa ban xia, strongest at resolving phlegm and stopping cough, used for copious phlegm with cough and phlegm-fluid dizziness; soaked in alum water — that is qing ban xia, gentler, used for damp phlegm. This patient’s chief complaint was vomiting, so Doctor Miao used jiang ban xia.
Next: guang chen pi (Cantonese aged tangerine peel, white pith removed), 4 liang — resolves phlegm and moves qi; fu ling (poria), 4 liang — drains dampness. Ban xia, chen pi, fu ling and licorice together are the famous Er Chen Tang (Two Aged [Ingredients] Decoction), the basic formula for damp phlegm (Doctor Miao left out the licorice here). To those he added zhu ling (polyporus), 2 liang, and ze xie (water plantain), 2 liang — both drain water and seep dampness; ze xie especially drains the water-dampness of the kidney channel. Then xuan fu hua (inula flower), 3 liang — everyone knows flower herbs mostly rise; xuan fu hua is the one flower that descends — zhu hua jie sheng, wei xuan fu hua du jiang: “of all flowers that ascend, only xuan fu hua descends.” Paired with ban xia it presses the rebellious qi back down. Hou po (magnolia bark), stir-fried in ginger juice, 1.5 liang — dries dampness and moves qi. Bai zhu (atractylodes), stir-fried in earth, 2 liang — tonifies the spleen-stomach and strengthens spleen earth’s transforming power. Zhi shi (bitter orange), bran-fried — breaks and moves qi, resolves phlegm and disperses accumulations, pushing the phlegm and fluid down and out.
And the finishing stroke: ren shen (ginseng), 1 liang. All the herbs before it move qi, circulate qi, and drain water-dampness outward — but that won’t do without upright qi. Ginseng tonifies upright qi; ginseng with bai zhu, fu ling and licorice is Si Jun Zi Tang (Four Gentlemen Decoction) (again, licorice omitted). So Doctor Miao’s formula combines strengthening the spleen, moving the qi, draining dampness, and resolving phlegm in one — Er Chen Tang and Si Jun Zi Tang standing inside the same prescription.
💬 Note from Doctor Luo: And the modifications are spelled out for you too: if the cause is damp-heat from drinking alcohol, add huang lian (coptis), 1 liang, and mu xiang (costus root), 5 qian; if it is cold-damp from cold drinks, add cang zhu (black atractylodes) — which dries dampness and is warm in nature — plus mu xiang and bai dou kou (white cardamom) to rouse the qi of the spleen-stomach; if it is depression and stagnation from bottled-up emotion, add zi su ye (perilla leaf), 4 liang — a generous dose; perilla leaf moves the qi, and it also balances the drying heat of cang zhu. There you are — cold, heat, and depression, three causes, three clear sets of modifications.
How it was taken: pills washed down with weak ginger soup — one dose stopped the vomiting, two doses cured
This formula was not meant to be decocted by the liang. Doctor Miao ground it to fine powder, cooked rice porridge, added a little ginger juice, and formed it into pills the size of mung beans. Each dose was 5 qian (about 15 g), swallowed with weak ginger soup, three doses in succession, also possible on an empty stomach. Ginger throughout — because ginger juice moves the qi and benefits the water.
For Lady Ge, Doctor Miao adjusted the formula slightly and made it as a decoction — with the ginseng at 3 qian (about 10 g). Prescribing for a patient isn’t done by rote; you scale the proportions into a soup.
And the result? One dose stopped the vomiting — after a single bowl, the vomiting ceased. The second dose brought sudden recovery — zai ji huo ran. The patient whose stomach had nearly been ruined by vomiting, whom other doctors had completely failed, was cured in two doses. Afterward she simply recovered on thin congee, letting the spleen qi slowly return. When the illness later flared up again, a few doses of this formula cured her at once.
💬 Note from Doctor Luo: Friends, this is the power of accurate pattern recognition. Doctor Miao saw at a glance that it was fluid, the logic was crystal clear, and the formula landed on target with the first prescription. If you ever meet a similar situation, you can borrow his thinking — no need for 4 liang in modern practice; 6 g or 9 g is plenty, and making it a decoction is perfectly fine. If you truly need treatment, ask a local Chinese medicine practitioner to guide you — that’s even better.
What to take away: the ancients classified finely because they truly saw and truly treated
The most moving thing about this case is the fineness of Doctor Miao Xiyong’s division of fluid disorders — dampness, water, fluid, phlegm; stopped below the heart, under the ribs, in the stomach, above the diaphragm, in the intestines — each with its own name, each with its own formula. We moderns speak vaguely of “water-dampness,” but the condition of a body that always holds water, that gushes clear water the moment an attack comes on, is absolutely real.
Chinese medicine is vast and profound — every bit you understand is better than not knowing. The two doses that cured Lady Ge did more than stop her vomiting: they left posterity a complete skill — “recognize clear water, and you can treat fluid.”
