Opening scene: a chancellor of the realm, running to the bathroom twenty-plus times a day

💬 Note from Doctor Luo: Today we continue with the healing stories of Doctor Luo Tianyi. Today’s patient is a man of no small importance — the Right Vice Chancellor of the Secretariat, which in modern terms is a minister of the highest rank, a chancellor-level official. Yet this great man was tormented by a most embarrassing complaint: he had to go to the bathroom more than twenty times a day, and each time barely a few drops came out. Frequent urination, scant urine — he could get no peace, day or night. Where did the illness come from? Doctor Luo Tianyi put it in one blunt sentence: he had been eating too well.

Who was the patient? He Chihesun, Right Vice Chancellor of the Secretariat

The patient was called He Chihesun (a transliteration of his Mongolian name), and he held the office of Right Vice Chancellor of the Secretariat — in the Yuan dynasty, the Secretariat (Zhongshu Sheng) was the highest governing body of the empire, and its right vice chancellor was a true minister of state.

💬 Note from Doctor Luo: Notice how in the old case records the patient is given name and surname, even his official rank, all written out clearly. Modern medicine protects privacy — patients are “Mr. So-and-so.” Not so back then: when the imperial physician treated a chancellor, the case record carried the real name and the real office. And this, in turn, shows just how reliable these case records are — when you treat an official of this rank, who would dare write carelessly? A mistake could cost you your head. So the cases Doctor Luo Tianyi left behind carry an extremely high degree of credibility.

How bad was it? Urinating often with little output, and legs so heavy he could hardly walk

In the spring of the guiwei year of the Zhiyuan reign (1283 AD), the vice chancellor fell ill. What were his symptoms?

• Frequent urination with scant output (xiao bian shu er qian): more than twenty trips to the bathroom a day, very little urine each time — shu means frequent, qian means insufficient;
• Fullness and distension of the abdomen: the lower belly below the navel felt bloated and uncomfortable;
• Heaviness in the lower back and legs: when walking, his back and legs felt extraordinarily heavy and leaden;
• Unable to sleep peacefully: even lying down felt wrong; he could not settle into rest.

💬 Note from Doctor Luo: When the Emperor saw his chancellor this ill, he issued an imperial decree ordering the imperial physician Doctor Luo Tianyi to attend him at once. Doctor Luo Tianyi took the pulse: deep and moderate yet replete (chen huan er shi), with occasional rapidity — deep and moderate indicated the disease was in the interior and tied up with dampness; yet it was not purely deficient, but carried a replete quality, and now and then the beat quickened unevenly. The moment his fingers met the wrist, he understood the case.

The diagnostic centerpiece: “Urinary difficulty has three patterns — you cannot treat them all alike”

Before opening his prescription, Doctor Luo Tianyi set down a rule: when the urine will not flow freely, you must not grab one formula just because the disease name looks familiar. In one breath he laid out three distinct patterns:

Pattern one: fluids diverted into the intestines. The body’s water ought to be apportioned evenly between stool and urine — the stool passes somewhat dry, and the urine flows. When this distribution goes wrong, the water all runs into the gut instead: the stool becomes loose or diarrhea, while the urine grows scanty and difficult. How to treat this? Restore the function between the large and small intestines — strengthen the spleen and astringe the stool while also promoting urination, so the water is redistributed. Doctor Luo Tianyi called this “a single act of redistribution” (yi fen li er yi) — just re-apportion the fluids, and the problem resolves itself.

Pattern two: heat binding in the lower burner. Dampness and heat tangle together, accumulate in the lower burner, and block things below, so the urine is squeezed down to less and less. The treatment here is called bland percolation to drain dampness (dan shen li shi): percolate the dampness out through the urine, adding a little heat-clearing medicine along the way. Once damp and heat are separated, the heat retreats on its own, and the fluids leave through the urine.

Pattern three: stagnation of spleen-stomach qi. The spleen and stomach are weak, the qi mechanism is stuck, the water passages cannot be opened, and water cannot be transformed and sent down to the bladder. The spleen normally governs the movement and transformation of water and dampness; when spleen qi is blocked, the water cannot be transformed. This pattern calls for moving the qi and fortifying the spleen and stomach: once the spleen and stomach are strong and the qi flows smoothly, the water passages open naturally.

💬 Note from Doctor Luo: Which pattern did the vice chancellor belong to? Doctor Luo Tianyi judged: chiefly the second — damp-heat accumulating in the lower burner; but with a touch of the third — the spleen-stomach qi mechanism was not quite flowing. How do we know? Look at his analysis of the cause — it is remarkably down to earth.

The cause: the trouble was “eating too well”

Doctor Luo Tianyi had served as an imperial physician for years and knew the bodies of the wealthy all too well. One look at the pulse and signs, and he knew: ordinarily the man lived on rich, fatty foods — he had been eating too well.

💬 Note from Doctor Luo: In Mongolian dietary custom, mutton is eaten in great quantity, and the table was piled high with rich, fatty delicacies. What happens when you eat too much rich, fatty food? Damp-heat builds up within — the body stockpiles dampness and heat. The damp-heat accumulates in the lower burner, the qi mechanism cannot turn, and the water stays trapped inside, unable to be transformed and carried away, so the bladder’s opening becomes blocked (pang guang qiao se): he wanted to urinate but could not, each time only a few drops came — and so the trips multiplied. That is the whole story behind “frequent urination with scant output.”

And Doctor Luo Tianyi made an especially frank remark: why should we study this formula? Because people today eat almost exactly like that vice chancellor. Middle-aged men with big bellies who still dash from one banquet to another through the evening — there are plenty of them, and many end up, just like him, defeated by urinary trouble.

The prescription: Fuling Hupo Tang (Poria & Amber Decoction) — one “sovereign” herb commanding a court of “ministers, assistants and envoys”

The treatment principle was settled: percolate and separate, drain dampness with bland herbs, and get the urine moving. The formula is called Fuling Hupo Tang (Poria & Amber Decoction).

The sovereign herb: Fuling (Poria). Doctor Luo Tianyi quoted the Neijing: “The liver is relaxed by sweetness, and drained downward by blandness” — sweet-tasting herbs relax, bland-tasting herbs percolate downward. This was a principle their school treasured (Zhang Yuansu → Doctor Li Dongyuan → Doctor Luo Tianyi): to fortify the spleen you must first dispel dampness, and sweet-bland percolation is a key move. Poria is precisely such a sweet, bland herb. Zhang Yuansu said it is slightly warm, able to dispel dampness and lift spleen qi upward, and also to percolate and drain water blandly; once the water-dampness is transformed away, the spleen relaxes — hence its power to fortify the spleen and harmonize the stomach; and beyond that it can settle the spirit and calm the heart. Poria is a hard fungal mass that grows clasping the roots of pine trees; the kind that grows wrapped around the wood is called fushen (Poria with hostwood), and it calms the spirit even better.

💬 Note from Doctor Luo: Poria was used enormously throughout Chinese history. Someone once did a count: in all the Chinese medical books from antiquity to the present, there are roughly over five hundred thousand formulas, and when they ran the statistics by computer — which single herb appears most often? Poria ranks first! What does that tell us? Dispelling dampness and fortifying the spleen has been the main theme of Chinese medicine for thousands of years. To be sure, the counting method is a bit crude — every disease and every formula differ, after all — but the very fact that Poria appears most frequently of all shows how dearly the ancients favored it.

Three minister herbs, helping Poria move the water:

• Huashi (Talcum): sweet and cold, able to smooth the passages and open the orifices, clearing summer-damp and damp-heat, draining the water downward while clearing heat. When damp-heat is bound together and the heat must be led out through the urine, talcum is the customary choice;
• Zhuling (Polyporus): like Poria, a fungus, and likewise a bland percolator that drains water. But there is a difference: Poria is gentle and is often used in nourishing formulas; Zhuling drains urine more forcefully and must not be taken long-term — drain too much water and the body cannot bear it, so it rarely appears in tonic formulas. Moreover, Poria’s nature tends upward, while Zhuling’s is mainly downward — when dampness is heavy and the water must be expelled urgently, add Zhuling;
• Hupo (Amber): the fossilized resin of pine trees, buried in the earth for years and years. Its medicinal actions are three: settling the spirit and calming the mind (some people wear amber on their chest; even skin contact can soothe the spirit — for palpitations, fright and unrest of the spirit, grind it to powder and take it with water), dispersing stasis and stopping bleeding (it invigorates the blood, dissolves stasis, and at the same time stops bleeding), and promoting urination and treating strangury (it enters the blood aspect and excels at resolving stasis — if urinary difficulty is caused by blood stasis, amber is the herb of choice).

💬 Note from Doctor Luo: Look at the name of the formula — Fuling Hupo Tang, Poria & Amber Decoction — the amber’s place in it is important precisely because it resolves blood stasis and opens the water passages. Speaking of this, I cannot help thinking of modern prostate problems: many prostate patients cannot pass urine, and when examined, stasis is often found inside. This line of thinking — and the Poria & Amber Decoction — I believe will have very wide application.

Two assistant herbs, fortifying the spleen and percolating dampness: the spleen detests dampness and loves dryness; when dampness is heavy, spleen qi cannot do its work. Doctor Luo Tianyi said, “one must use sweetness as the lead,” and added Baizhu (Atractylodes macrocephala) and Gancao (Licorice) to fortify the spleen — this was his nod to the third pattern (stagnation of spleen-stomach qi): clear the damp-heat while protecting the spleen and stomach.

Two envoy herbs, the finishing touch:

• Zexie (Alisma): “saltiness enters the kidney, and salty flavors drain downward as yin” — Alisma is salty in taste, able to drain hidden water from the kidney. Zhuling paired with Zexie is a classic treating both spleen and kidney combination;
• Guizhi (Cinnamon twig): acrid and warm, warming and freeing the qi transformation.

💬 Note from Doctor Luo: When Doctor Luo Tianyi wrote up his cases he loved to anchor his reasoning in the Neijing; here he cited “when the kidney suffers dryness, urgently give it acrid flavors to moisten it,” using the acrid, warm cinnamon twig to moisten the kidney and assist qi transformation. But reading that sentence alone is not enough — the addition of cinnamon twig is brilliant: think about it — the whole formula is made of sweet, cold, bland, percolating herbs, a whole current of coldness flowing downward. The water is being drained, yes — but who is going to drive the qi transformation? It is like a little boiler whose fire is too weak: the water never comes to a boil, and no steam is produced — at that point you must add a little flame. Cinnamon twig is that flame: acrid and warm, it stirs qi transformation and gets the water-dampness moving; it can also course the liver and move qi — the liver governs free coursing, so when the body has stagnation, adding one herb that courses the liver restores normal function, and the whole strategy becomes complete. That is why in this formula the cinnamon twig is used in a considerable dose (three qian, about 9 grams) — it is no walk-on extra, but a real working measure.

The decoction detail: “Ganlan water,” lifted and poured a thousand times

The formula was settled — but how should it be decocted? Doctor Luo Tianyi required Ganlan shui (swept water, also called chang liu shui, long-flowing water) for the preparation.

💬 Note from Doctor Luo: What is Ganlan water? Take water from a constantly flowing river or stream, put it in a basin, and with a ladle scoop it up and pour it back, over and over, a thousand times — keep it up for hours, until tiny beads of water roll and bubble across the surface — that is Ganlan water. The ancients were particular about the water for boiling medicine, just as tea connoisseurs are particular about the water for steeping tea: different waters, different results. Medicine decocted in Ganlan water carries a lighter medicinal force; the formularies always say it “does not assist kidney qi” — meaning it does not add burden to the kidneys.

Does that sound mystical to modern ears? Doctor Luo Dalun addressed it directly: people have actually run experiments — lift and pour the water a thousand times and the droplets look exactly the same as before; the change the old books describe does not show up. Yet the ancients’ feel for physical detail was extremely refined — dead water and living water truly are different: leave a bottle of mineral water for two years and the molecules clump together through static charge into “dead water”; shake it vigorously and the clumps break apart into “living water” again — even the oxygen content changes. The biggest fish gather at the little waterfall in a stream precisely because the tumbling spray churns, touches the air, and carries more oxygen. Lifting and pouring water a thousand times also subtly shifts the molecular clusters and oxygen content — the ancients grasped this and used it for their decoctions. Nobody decocts with Ganlan water today, but this “living water” culture is worth remembering — if you truly care, giving the water a spin with a blender works on the same principle.

The outcome: halved in two doses, essentially cured in ten days

The medicine was prepared and presented to the Right Vice Chancellor. What happened?

“Two doses, and it was halved” — after drinking the decoction twice, his suffering was cut in half; “xun ri liang chai” — within about ten days, he was essentially well.

💬 Note from Doctor Luo: Look at how Doctor Luo Tianyi prescribed — every herb has its textual basis: the theoretical guidance of the Neijing, which flavor treats which part of the disease, where it is positioned — all spelled out with perfect clarity. Cases like this are what make a classic. How many people around us today resemble that vice chancellor — rich, fatty food every day, until at last the urine will not flow and they crouch in the bathroom unable to pass a drop? For those whose damp-heat has accumulated in the lower burner, would it not be worth consulting Doctor Luo Tianyi’s line of thinking? That is the lesson of this case.

What to take away

• “Eating too well” can genuinely block your urine: a constant diet of rich, fatty, heavy food stockpiles damp-heat in the lower burner, clogs the bladder’s opening, and produces exactly this pattern — frequent trips to the bathroom with only a few drops each time.
• Three patterns, three treatments: if fluids are being diverted into the gut (loose stool plus scanty urine), redistribute them; if damp-heat binds the lower burner, percolate the dampness with bland herbs and clear heat; if spleen-stomach qi is stagnant, move the qi and fortify the spleen. Never treat every case of urinary difficulty with a single formula.
• The Poria & Amber approach: sweet-bland Poria percolates dampness and fortifies the spleen; amber resolves stasis and opens the water passages — a line of thinking worth remembering for modern prostate-type problems in which stasis is often present.
• Don’t forget the little flame: in a formula of cold, draining herbs, a touch of acrid, warm cinnamon twig keeps qi transformation alive — the whole system needs someone to drive it.
• Respect the water: the ancients chose their decoction water with care. The “living water” idea — fresh, aerated, moving water — is a piece of that culture worth keeping in mind even if you never lift a ladle a thousand times.
