Opening: the provincial official who was worn down by his own desk

Today Doctor Luo Dalun tells the case of Doctor Zhang Jingyue, the great Ming-dynasty physician. And he starts with a confession: when he was a child studying Chinese medicine, he secretly chose an ancient teacher for himself — and that teacher was Zhang Jingyue. Why? Because Zhang Jingyue was so complete, so deep in his learning: ask him about anything, and he could basically explain it all.

💬 Note from Doctor Luo: Zhang Jingyue (Zhang Jiebin, style name Jingyue, 1563–1640) is one of the most celebrated physicians of the Ming dynasty; later generations credit him with laying the foundation of the eight-principle pattern identification (ba gang bian zheng) system. He was immensely learned — astronomy above, geography below, a master of music, and thoroughly versed in the I Ching (Yijing). Without that kind of foundation, you can’t properly explain the Huangdi Neijing (Yellow Emperor’s Inner Classic). He also organized the Neijing into the Lei Jing (Classified Classic), which became the official textbook used by the Qing dynasty’s Imperial Medical Academy to train imperial physicians — that status is no small thing.

Who was the patient? Zhou, the forty-something official who poured out his essence

The patient’s surname was Zhou, and he served as an official in the provincial government (hence “sheng zhong Zhou gong”). He was a native of Shandong (called shan-zuo in the classics). In his forties — in the prime of life — yet he fell critically ill.

Where did the illness come from? “Yin an du zhi lao” — the toil of official paperwork. Day after day of exhausting deliberation, work that never ends, every thought spent on government affairs. Slowly, the man was boiled down into a hollow, weakened shell: spirit exhausted, no energy, and his appetite faltered — he couldn’t eat.

Stranger still, he lived with a constant feeling of dread — as if something terrible were about to happen.

💬 Note from Doctor Luo: This kind of fear only appears when the deficiency has gone deep. When the heart and its channels are drained to a certain point, with both qi and blood depleted, an unexplained fear sets in — on one level he’s afraid of his own body giving out: “Am I about to die?” On another level he’s afraid of the outside world too, feeling something bad is coming. Patients describe it strangely, but when the illness reaches that stage, that is simply how it is.

How bad was it? Half a year without real sleep, and urine gushing like an opened sluice

The illness dragged from winter to spring and on into summer. The most tormenting symptom: not a single proper night’s sleep for over half a year — lying awake, tossing and turning, night after night.

💬 Note from Doctor Luo: To be fair, “not a wink for six months” is an exaggeration. Sleep researchers have wired up patients who swore they hadn’t slept at all, and found they actually did sleep — but so shallowly, with no dreams at all, that waking felt blank; all they remembered was the sleepless stretch, so it seemed they’d been awake all night. Truly going without sleep for one night, and a person collapses within days. So Zhou was sleeping terribly poorly — not literally keeping his eyes open for six months.

By day he wasn’t thirsty and didn’t want to drink; on the rare occasions he took a sip, the water seemed to vanish — it never turned into urine. But at night, the urine came gushing — two or three times a night, in large volumes, two to three liters in total, and no one could figure out where the water was coming from. Elderly people often have exactly this: barely drinking all day, yet up again and again at night, passing a lot each time, wondering “where is all this urine coming from?”

The most frightening symptom: urine like paste — the essence leaking away

And the urine had a special quality — “ru gao zhuo ye”: half of it was a thick, pasty, turbid liquid.

💬 Note from Doctor Luo: In Chinese medicine this kind of urine is called “lin zhuo” (turbid strangury). What is being drained away is actually the body’s finest essence — the essential substances leaking out. Urine like this is never a good sign. Can’t drink by day, leaking essence by night, exhausted, appetite gone — Zhou himself concluded: “This time I’m finished for sure.”

Doctor Zhang Jingyue takes the pulse: the pulse is calm, the flesh intact, stomach qi still present — we can save him

The patient himself was certain he was dying; the family hurriedly called in Zhang Jingyue. One touch of the pulse, and Zhang Jingyue said: “The pulse is still calm (mai you dai huan); the flesh has not fallen away; stomach qi is still present — there is nothing to worry about.”

💬 Note from Doctor Luo: A racing pulse means the illness may still be advancing; a calm pulse shows the upright qi is still composed, not jumping wildly. And looking at the man — thin, yes, but the flesh had not melted away, which shows stomach qi is still there. Chinese medicine says “where there is stomach qi, there is life” (you wei qi ze sheng): as long as the spleen-stomach qi remains, the patient can be saved. Zhang Jingyue was confident, and first comforted the patient: it’s all right, I’ll regulate you.

The key diagnosis: spirit consumed above, essence consumed below — xiaoke is not always about fire

Zhang Jingyue’s diagnosis was four characters: “shen xiao yu shang, jing xiao yu xia” — the spirit is consumed above (hence the sleeplessness and dread), and the kidney essence is depleted below (hence the pasty night urine and leaking of essence).

💬 Note from Doctor Luo: A little background first. Zhang Jingyue’s Jingyue Quanshu (Complete Compendium of Jingyue) is an encyclopedia of Chinese medicine. Every disease gets a fixed structure: first he gathers everything the Neijing says about it (the “jing yi,” canonical meaning); then he discusses the symptoms and patterns (“lun zheng”); then the treatments and formulas (“lun zhi”); then he attaches the writings of later masters — Li Dongyuan, Zhang Jiegu, Zhu Danxi — (“shu gu,” recounting the ancients); and often finishes with cases and a formulary. A beginner should go to the Jingyue Quanshu first for any disease, get his bearings, and only then read other books.

Now, xiaoke (wasting-thirst — what the ancients called it, which overlaps considerably with today’s diabetes). It has three forms: upper xiaoke — thirst, drinking without end, still thirsty after drinking; the fluids of the upper burner are exhausted and there is heat. Middle xiaoke — voracious appetite, constantly hungry, always needing to eat; somewhat like the “faint with hunger” of diabetic hypoglycemia; it’s a spleen-stomach matter. Lower xiaoke — a kidney-channel disease: urine gushes out in streams, yellow-red and turbid like paste, with the face turning dark, the ears shriveling, the body wasting. The ancients assumed xiaoke must always involve fire, but Zhang Jingyue pointed out “xiao has yin and yang”: fire blazing and injuring yin is yang xiao. But there is also yin xiao — yang qi deficiency: “jin han shui leng, qi bu hua shui” — the metal (lung) and water (kidney) are cold, water cannot transform into qi, so it all pours out as urine; the more deficient, the more it leaks. As Zhang Jingyue wrote, “you can see that xiao has yin and yang; you cannot speak of fire in every case.” Most ancient treatments assumed fire and cleared fire. But this Zhou was someone who overworked his mind — heart and kidney both depleted. Exhausting the spirit drains the kidney essence; kidney essence is the fundamental substance of life, and day after day of deliberation is day after day of spending it. When kidney essence runs low, kidney qi is insufficient and cannot transform and govern water — water cannot be held, and it pours out; the upright qi is weak and cannot keep a grip, so the essential substances leak out with it. This is yin xiao / xu xiao (deficiency-type xiaoke) — it must be slowly replenished, not cleared of fire.

The prescription, unpacked: Guipi Tang nourishes yang, Dabuyuan Jian nourishes yin — the two alternated

Zhang Jingyue prescribed two formulas, “chu ru jian yong” — using them in alternation: Guipi Tang minus mu xiang (Spleen-Restoring Decoction without costus root), and his own invention, Dabuyuan Jian (Great Replenishing the Origin Decoction).

💬 Note from Doctor Luo: Guipi Tang nourishes yang; Dabuyuan Jian nourishes yin. How to use them? For example, Guipi Tang in the morning and Dabuyuan Jian at night; or Guipi Tang for a stretch, then Dabuyuan Jian for a stretch — the two rotating. Guipi Tang is a dual tonic for qi and blood (modern formulary texts file it under blood-nourishing formulas): built on Sijunzi Tang (Four Gentlemen Decoction) with qi-tonifying as the base, plus blood-nourishing and spirit-calming herbs — especially suited to people who have exhausted their minds: office workers who think all day, children studying too hard. When overthinking injures the heart spirit and drains heart blood and heart qi — insomnia, palpitations, even the spleen failing to govern blood — Guipi Tang works remarkably well.

Dabuyuan Jian is the first formula of the tonic battle-array (bu zhen) in Zhang Jingyue’s “new eight arrays.” In his youth Zhang Jingyue served as a staff officer with Li Rusong’s expedition to Korea and knew military strategy, so he arranged his formulas in “eight arrays”: tonic, harmonizing, attacking, dispersing, and so on. First in the tonic array is Dabuyuan Jian, for men and women whose qi and blood are gravely ruined and whose spirit has lost its hold — Zhang Jingyue called it “the very first formula for turning back heaven, aiding transformation, saving the root and cultivating the origin.”

The ingredients are plain, but the logic is razor-sharp:

• Ren shen (ginseng) — tonifies the qi of the heart and lungs, building the upper burner;
• Shu di huang (prepared rehmannia) — tonifies kidney essence and nourishes yin; as little as two or three qian or as much as two or three liang, the proportions adjusted freely;
• Shan yao (Chinese yam) — tonifies the spleen;
• Dang gui (Chinese angelica) — nourishes the blood;
• plus du zhong (eucommia) to open the collaterals and strengthen the lower back, shan zhu yu (cornus) to nourish liver yin, gou qi zi (wolfberry) to replenish the essence of liver and kidney, and zhi gan cao (honey-fried licorice) to harmonize.

💬 Note from Doctor Luo: The core logic of this formula runs along the same road as Liuwei Dihuang Wan (Six-Ingredient Rehmannia Pill) — prepared rehmannia tonifying kidney essence as the foundation; kidney essence is the root of life. On that base: need qi, add qi tonics (ginseng, huang qi, bai zhu); need blood, add blood tonics (dang gui); need spleen, add shan yao. If yang qi is insufficient, add fu zi, rou gui, pao jiang; if qi deficiency predominates, add huang qi and bai zhu; if blood isn’t moving, add chuan xiong; if there’s slippery diarrhea, add wu wei zi and bu gu zhi. Zhang Jingyue’s whole method is: tonify the kidney essence as the base, then build upward as needed — kidney essence is the root; everything else is branches and leaves.

Three hundred doses and twenty jin of ginseng: pulling a life back from the brink

How long did the treatment take? More than 300 doses, with about 20 jin (roughly 12 kg) of ginseng in total, before he recovered. A genuinely slow craft.

💬 Note from Doctor Luo: The danger with replenishing is replenishing on one side while consuming on the other. If you keep exhausting your spirit with deliberation, no amount of tonic can catch up. So the treatment demanded resting the mind, calming the spirit, and slowly building up. Twenty jin of ginseng, 300-odd doses — that is truly pulling a person back from the death line, inch by inch. Even today this illness would be very hard to manage. It overlaps with diabetes: in the late stages of diabetes, patients waste away terribly, ulcers and kidney failure are common — diabetic nephropathy ending in kidney failure is seen all the time in the clinic.

For modern readers: elderly people with heavy night urination should think about tonifying kidney essence

Doctor Luo closes with a specific piece of advice: many elderly people pass urine a lot at night — it is genuinely worth considering whether the kidney essence needs replenishing.

💬 Note from Doctor Luo: Zhang Jingyue’s medicine was built on seeking truth from facts — he identified patterns with extraordinary precision. The three xiaoke (wasting-thirst) are not all fire: there is yang xiao and there is yin xiao; the yang-deficient type must be slowly restored. Modern people resonate with this case enormously: desk-bound toil, too much mental expenditure, too much anxious thinking — how similar we are to that Ming official. So when regulating the body, remember these “replenish slowly, don’t consume” principles.

What to take away

1. Not all xiaoke (diabetes-like conditions) are fire. Fire-blazing that injures yin is yang xiao; but there is also yin xiao — cold metal and water, qi unable to transform fluids, the essence leaking out as pasty urine. Clear fire blindly, and you injure the patient further.
2. Overthinking drains kidney essence. The kidney essence is the root substance of life; endless deliberation spends it day by day. When the essence is depleted, qi loses its grip — urine pours out, essence leaks with it.
3. Two formulas, one yang one yin. Guipi Tang (minus mu xiang) for qi and blood, calming the overworked spirit; Dabuyuan Jian, the first tonic of Zhang Jingyue’s battle-array, built on prepared rehmannia tonifying kidney essence — the two alternated day by day or week by week.
4. A calm pulse, intact flesh, stomach qi present — still savable. “Where there is stomach qi, there is life.” Even in dire exhaustion, if the pulse is calm and the flesh hasn’t melted away, the root of life remains — slow replenishment can still pull the patient back.
5. For modern readers: elderly people with heavy nocturia, night after night of large volumes of urine, fatigue and poor appetite — don’t just shrug it off. Consider whether the kidney essence needs building up, slowly, without further consumption.
