Legs and Feet Swelling, Urine Drying Up?

The swelling crept up from the soles of her feet

Today’s case is special — special because of the medicine. The great Qing-dynasty physician Doctor Wu Jutong (吴鞠通) wrote a prescription for an elderly woman that weighed more than half a kilogram for a single dose. He used cinnamon bark and cassia twig in amounts that ordinary doctors would not dare imagine. Listen closely.

The patient, a woman named Hong, was 68 years old. In ancient times, living to nearly seventy meant she had reached a venerable old age — and the illnesses of the elderly have never been easy to treat. What she suffered from was edema: a body full of water that could not be drained.

💬 Note from Doctor Luo: There is an old saying: “Men fear pulling on boots; women fear putting on hats.” Men dread swelling that starts in the legs, as if pulling on a pair of boots; women dread swelling that starts above, as if putting on a hat. But this is not a hard-and-fast rule — swelling that rises from below can be just as dangerous.

Who was the patient? Thirty years a widow, heavy and full of sorrow

Ms. Hong had been widowed for more than 30 years — her husband died young, and she had lived alone, keeping her widow’s vow for over three decades.

💬 Note from Doctor Luo: Those thirty years were not kind to her. Her two defining traits: she was very heavy-set — a large, stout body — and she had been depressed for decades — more than thirty years of grievances and disappointments, all locked inside. Her liver qi had been bound up and unhappy for a very, very long time.

From the very first lines, Doctor Wu Jutong located the origin of the illness: this disease was inseparable from emotion.

The root cause: it all came down to “emotion”

When depression goes on for years, the qi inside the body can no longer circulate freely; and when qi does not circulate, over time cold yin accumulates within. Recently, Ms. Hong had also suffered a bout of violent rage and deep worry — and when the emotions flare, the Jueyin (Liver channel) and Taiyin (Spleen channel) fall ill together. Water can no longer move as it should: the water that ought to be expelled stays in, and the urine stops flowing.

And so the swelling began at the instep — creeping up from the top of the foot and the calf, little by little.

How serious was it? Six pulses thin as silk thread

Doctor Wu Jutong took one look: so old, so heavy, so unhappy, and the swelling climbing up from the feet — this was no light illness. He felt her pulse: all six positions were sunken and thready, thin as a strand of silk.

💬 Note from Doctor Luo: Doctor Wu Jutong’s verdict was immediate: “This is certainly not something light doses can handle.” The yin was too heavy, the yang too weak — nothing but a heavy hand would do.

Doctor Wu Jutong’s thinking: swelling below the waist calls for promoting urination

Doctor Wu Jutong followed an ancient and vital rule of treatment: when the swelling is below the waist, promote urination — drain the water out through the urine.

What formula did he use? Wuling San (Five-Ingredient Powder with Poria).

💬 Note from Doctor Luo: Wuling San is the famous warming-yang-and-promoting-urination formula handed down by Zhang Zhongjing (张仲景), the founding father of clinical Chinese medicine. It treats both the surface and the interior — a truly remarkable creation. Why warm the yang? Think of it this way: kidney yang is the fire under the stove. When kidney yang is insufficient, the bladder loses its power of qi transformation — the water that should be distributed is not distributed, and the water that should be expelled is not expelled. It is like the sun slowly being covered by clouds while the mist grows thicker and thicker. When the yang inside the body weakens, dampness begins to flood. Warming yang to dispel dampness is one of the most famous strategies in Chinese medicine, and Wuling San is its representative work.

Dissecting the prescription: reading the wisdom herb by herb

This prescription was written with great precision. Let us take it apart, one ingredient at a time:

• Gui zhi (cassia twig), 15 g — warms yang and transforms qi, opens the channels — and, notably, it also soothes the liver qi. Wasn’t the problem a bound-up liver? The cassia twig does double duty.
• Rou gui (cinnamon bark), 12 g — Doctor Wu Jutong was especially skilled with cinnamon bark. Cassia twig and cinnamon bark come from the same tree: the tender young branches are the twig, while the bark of the lower trunk is the cinnamon. Cinnamon bark is the dedicated yang-warmer, and it also has the ability to draw qi downward.
• Fu ling pi (poria peel), 18 g — we usually use the whole poria sclerotium; the peel has an even stronger power to drive out dampness.
• Zhu ling (polyporus), 15 g — works with poria to drain water, opening the “valve” below so the water can leave.
• Ze xie (alisma), 15 g — enters the kidney channel and opens the waterway of the bladder. Poria, polyporus, and alisma are precisely the three herbs in Wuling San that “transform water and push it outward.”
• Sheng cang zhu (raw atractylodes lancea), 15 g — note that he did not use bai zhu (atractylodes) here but cang zhu (atractylodes lancea). Cang zhu “moves without staying” — strong at draining water; bai zhu “stays without moving” — strong at tonifying the spleen. When you need the water to leave in a hurry, you reach for cang zhu.
• Guang pi (tangerine peel) — moves qi and opens the lung qi so that water can be transformed — once the lung qi opens, all the qi of the body can circulate. This is called “opening the upper source of water.”
• Hou po (magnolia bark), 12 g — regulates qi, moves qi, and resolves dampness, helping push the water-damp downward and out.

💬 Note from Doctor Luo: Zhang Zhongjing laid the foundation of clinical practice; with a single Wuling San he established the method of warming yang and dispelling dampness, and even today this approach still works with striking immediacy. I love using Wuling San in my own clinic — modern people carry far too much water-damp. When I see a swollen tongue with teeth marks, a thick greasy coating, and obvious water-damp, I build on a base of Wuling San, adding aromatic herbs that resolve dampness and open the middle burner, such as huo xiang (patchouli), pei lan (eupatorium), and bai dou kou (cardamom seed), sometimes with a little yi yi ren (job’s tears). Once the dampness is removed, the body begins to recover.

The prescription was made up, cooked into three cups, taken in three doses. Surely it would work now, right? But then —

Setback one: five doses, and not the slightest change

The patient took it for three to five doses, with no effect — not worse, but not better. The urine still did not grow; the volume stayed exactly the same.

💬 Note from Doctor Luo: If the qi-transformation function were normal, the urine should pour out in a torrent and the swelling should dissolve. When the urine will not grow, something is wrong.

Setback two: raise the dose! Cinnamon by the handful, cassia twig by the half-pound

Doctor Wu Jutong judged: the direction of treatment is not wrong — perhaps the dose is insufficient. Increase it!

Cinnamon bark was raised to 60–90 g; cassia twig to 120–150 g. In one single dose, just the cinnamon and cassia twig alone reached this enormous quantity. The whole prescription, weighed out, came to more than half a kilogram, decocted into five or six bowls, to be drunk in a single day.

💬 Note from Doctor Luo: My goodness — even I was stunned reading this. Sixty to ninety grams of cinnamon bark, one hundred twenty to one hundred fifty grams of cassia twig! In all the case records I have read across the ages, Doctor Wu Jutong is the only physician I have ever seen dare to use such ferocious doses. It has to do with his own experience: when he was young, he caught a cold and used Gui Zhi Tang (Cassia Twig Decoction), made it up in the full quantities of Zhang Zhongjing’s original text, drank a big pot, and recovered almost immediately. From then on he believed that the ancient doses (from Zhang Zhongjing’s time) really were large, and he dared to use them in full. Please, everyone, do not imitate this at home!

And the result? After five or six days of this, the six pulses did not rise in the slightest — the pulse was still weak, the swelling had not gone down, and the urine still would not grow.

Doctor Wu Jutong’s verdict: if the cinnamon fails, there must be stagnation

When even such ferocious yang-warming medicine produced no response, one can see how deep the cold-yin was. Doctor Wu Jutong said: “Why? Because the cinnamon was not good.” — the quality of the cinnamon itself was poor!

💡 Note from Doctor Luo: Doctor Wu Jutong cared enormously about authentic, geo-authentic herbs (dao di yao cai). When the medicine is genuine, it works the moment it is used; when it is not genuine, even a dose this huge accomplishes nothing. At the same time, he understood something else in his heart: after years of depression and a recent attack of rage that injured the liver, there must be stagnation inside — the blockage was simply too severe.

What to do? Doctor Wu Jutong reached for a special move: keep the original formula exactly as it was (at the huge dose), add 18 g of Ji Shi Li (Chicken-Droppings Fermented Drink), and add 24 g of fu zi (aconite) to strengthen the yang-warming power.

The secret weapon appears: Ji Shi Li from the Huang Di Nei Jing

This Ji Shi Li — is chicken droppings.

💬 Note from Doctor Luo: Don’t laugh — this is a formula straight from the Huang Di Nei Jing (Yellow Emperor’s Inner Classic). That vast and profound classic actually records only 13 formulas in total, and they are very simple ones. The ancients believed that if you keep your emotions in order — calm, empty, and free of desire — you rarely fall ill; and when a minor complaint appeared, they would first press acupoints, needle, or moxa, using medicine only as a last resort. Those 13 formulas are all simple: sheng tie luo (iron filings) — the iron dust knocked off a blacksmith’s anvil, boiled into water for mania; ban xia shu mi tang (Pinellia and Sorghum Decoction) — insomnia, treated with pinellia and sorghum. And the one for edema was Ji Shi Li. How was it made? You take a rooster, feed it sorghum for a few days to cleanse its intestines, then collect the droppings (the white portion), dry and roast them on a tile until scorched, then take them with boiling water, drinking it like tea. The ancients said “one dose and you know, two doses and it is done” — one or two doses should finish the job. Some people steeped it in wine, but according to the statisticians among the old physicians, the wine version worked poorly — just take it in water.

💬 Note from Doctor Luo: What does Ji Shi Li do? It clears stagnation and purges the triple burner — once the stagnation blocked inside the body is cleared, the edema slowly recedes. But this remedy was endlessly debated by physicians through the ages; case records using it are extremely rare, and today almost nobody uses it — it sounds disgusting, after all! Yet among the common people it is still used, and in cases of truly severe edema it is worth trying. Doctor Wu Jutong was a master of finding new uses for ancient formulas — his treatment of the “Sun Simiao carp soup” was another case of borrowing inspiration from the classics. The old physicians argued about whether Ji Shi Li worked; he did not care. The ancients said it was good, so he simply put it into his prescription and used it!

The turning point: once the urine flows, the water pours away

After adding the aconite and the Ji Shi Li — the urine gradually began to flow, and the output started to increase.

💬 Note from Doctor Luo: The ancients recorded that this thing worked — and they were not writing nonsense. We simply have not mastered the method. Doctor Wu Jutong used it correctly, combining it with the yang-warming aconite, and the urine flowed.

Seven consecutive doses: the swelling gradually receded; the appetite gradually returned — she began to eat more; the complexion brightened — that gloomy, sunken face began to come alive. So he gradually reduced the earlier doses — 60 grams of cinnamon was too much, and it was slowly dialed back.

In all, 14 days (half a month) of treatment — and the swelling was completely gone.

💬 Note from Doctor Luo: Everyone, consider this: a 68-year-old woman with such heavy swelling, completely resolved in half a month — that is no small feat!

Aftercare and closing the case: tonify the spleen yang, soothe the liver qi

Once the swelling was gone, how did he follow up? Tonify the spleen yang and soothe the liver qi — strengthen the spleen on one side, smooth the liver on the other, and bring the case to a close with slow, steady regulation.

💬 Note from Doctor Luo: This case teaches two different ways of treating illness. Some diseases need long-term, gradual regulation — slow change, quantity turning into quality. Other acute situations cannot wait: they demand heavy doses and fierce medicine to overturn the situation first, and only then small spleen-tonifying, liver-soothing formulas to close the case — even a few pills will do. But using fierce medicine in the overturning stage requires real skill. This is not something to try casually.

Epilogue: great skill makes for great daring — but do not imitate it

The most valuable thing in this case is Doctor Wu Jutong’s spirit of exploration. The direction was right, but it did not work — so he asked himself: is the quality of the medicine poor? Or is the dose insufficient?

💬 Note from Doctor Luo: There is a saying in Chinese medicine: “The unspoken secret of Chinese medicine lies in the dose.” When treatment fails, the reason is often one of two things: the herbs are of poor quality, or the dose is too small. Some timid doctors give one or two grams of ma huang (ephedra) at a time, a few grams here and there — of course nothing happens. Doctor Wu Jutong gave the full dose from the start, and the illness responded. A prescription with 120 to 150 grams of cassia twig — no ordinary pharmacy would dare fill it. Only people who knew it was written by Wu Jutong would even hand it over. This is what they call “great skill, great daring.”

💬 Note from Doctor Luo: To be honest, I have never used it this way myself — I have dared to use 200 grams of huang qi (astragalus), but cassia twig and cinnamon bark in these quantities, no, never. When you hear this case, let it open your eyes and widen your horizons: such things really happened in history, and it is worth knowing that they did. And if one day you face a crisis where the situation must be turned around at once, maybe then heavy doses will be called for. But in ordinary life, please never experiment at home — you do not have Doctor Wu Jutong’s skill!

The 68-year-old Ms. Hong carried a body full of water that climbed from her instep to cover her whole frame. Doctor Wu Jutong kept the direction and kept raising the dose, and finally called upon the Chicken-Droppings Fermented Drink from the Huang Di Nei Jing — and in half a month, a body full of water was gone. The direction was right; all that was missing was a bigger fire. That is the learning hidden in the dose.

What to take away

• Edema below the waist calls for promoting urination — an ancient rule that still guides treatment today. Wuling San is its classic representative: warming yang, transforming qi, and letting the water leave through the urine.
• Emotion can be the root of the water. Decades of suppressed grief and a sudden storm of rage disturbed the liver and spleen channels, and the water could no longer move. When treating swelling, ask about the life and the feelings, not just the legs.
• Cang zhu moves and drains; bai zhu stays and tonifies. For water that must leave quickly, the physician chose cang zhu — herb choice is always tailored to the job at hand.
• When the right medicine at ordinary doses fails, the dose itself may be the missing fire. But dose is the unspoken secret of the craft — the huge amounts in this case are for viewing, not for copying. Never reproduce them at home.
• The ancients recorded Ji Shi Li — chicken-droppings drink from the Huang Di Nei Jing — as a way to clear deep stagnation. It sounds strange, but it reminds us that the classics hold remedies far stranger than we imagine, and that a master can find new uses for the oldest formulas.
