Opening scene: a child falls into a pond

In the late Ming and early Qing dynasty there lived a famous physician named Doctor Yu Jiayan. He had a distinctive way of practicing: he was exceptionally skilled at using the formulas of the Shang Han Lun (Treatise on Cold Damage), and his diagnosis was extraordinarily precise — especially when it came to heat patterns. Even though the Shang Han Lun deals mainly with cold pathogens, his understanding of heat was unusually clear, which made him a rarity among the physicians of his time.

💬 Note from Doctor Luo: Today’s story is one of his classic cases. The protagonist was a gentleman named Yuan Zhongqing, whose child was playing by the pond catching small crabs (in the old days people called these little crabs peng qi). He lost his footing — “glug” — and fell straight into the water. In the south, children falling into ponds and streams was a common occurrence, and the family scrambled to pull him out.

He was rescued — but then the fever came

After being pulled out, the boy seemed fine at first. But after a while, his body began to run hot — a fever — and he moaned in pain. The family quickly called a pediatric doctor.

The pediatrician took one look: wasn’t this a fright? In those days, cases like this were routinely treated as “acute fright wind” (ji jing feng) — with settling-the-fright, clearing-heat medicines such as ox bezoar (niu huang) and heavy mineral preparations, made into pills or powders for the child.

💬 Note from Doctor Luo: Remember this pattern — “the child was frightened, so settle the fright and clear the heat.” It was a very common pediatric approach in the past. The problem is, after two days of taking the medicine, the child not only failed to improve — he fell into a coma! And the symptoms turned frightening: his chest (the stomach region) bulged up three inches, his neck went limp, his head lolled to one side, and his breathing grew so shallow it seemed he might stop at any moment. The family decided the boy was dying and sent urgently for Doctor Yu Jiayan.

Both physicians shook their heads: a pulse like a spider’s thread, a nose black as soot

Doctor Yu Jiayan arrived, took the pulse, and his heart sank — the pulse was barely a “spider’s thread,” so thin it vanished as soon as he pressed. He sighed and said: no matter how severe the outward signs, I have never been afraid; but this pulse has lost its root. It will be very hard to save.

Beside him sat another physician, a Doctor Zhao, who examined the child’s nose and pronounced: the nose is black as soot — the nostrils black as if smoked. This is lung qi exhausted; even a magic elixir could not save him now.

💬 Note from Doctor Luo: Here’s a teaching point. “Nose black as soot” is a special sign in Chinese medicine — blackened nostrils as if smoke-stained. Later the Warm Disease school clearly recognized it as a sign of warm-heat pathogen entering deeply, with dry heat bound in the interior. But in those days (before the Warm Disease theory had risen), everyone took it as a fatal sign of exhausted lung qi. Watch Doctor Yu Jiayan here — the pulse was almost gone and everyone said it was hopeless, yet he did not give up. He asked everyone to step back, sat alone in quiet reflection, and thought for a very long time.

He figured it out: how did the illness reach this point?

Suddenly Doctor Yu Jiayan slapped his thigh: “I’ve got it!” The father was startled and overjoyed; the other physician pricked up his ears, eager to hear the explanation.

Doctor Yu Jiayan said: yes, the child had a fright — but look at how he fell ill in the first place. He fell into freezing cold water and caught cold-damp evil qi — fundamentally the same as catching a cold from wind-cold. What’s more, the boy had almost certainly eaten before falling in, so food was sitting undigested in his stomach. When the external pathogen arrived, his upright qi (zheng qi) was insufficient, the stagnation couldn’t be moved, and it blocked the interior — in classical terms, this is “jia shi shang han” — cold-damage complicated by food stagnation!

💬 Note from Doctor Luo: This is the crux of the whole case. If it were plain cold damage, you could treat it by following the six-channel progression. But “jia shi shang han” is different — besides the external cold-damp, there is the extra factor of food stagnation, so in addition to dispersing cold, you must also eliminate the food stagnation for the child to recover quickly. Properly speaking, Wusan San (Five Accumulations Powder), from the Taiping Huimin Heji Ju Fang (Formulary of the Pharmacy Service), was the ideal first choice — it releases the exterior (with ma huang, ephedra), warms the interior (with gan jiang, dried ginger), moves blood and resolves stasis (with chuan xiong, ligusticum), removes dampness and phlegm, regulates qi, and also aids digestion — broad and complete in direction. But the earlier physician didn’t use it; instead he used heavy, settling, cold mineral medicines, which drove the external pathogen straight into the organs. The cold was “ice-packed” inside the body, and the consciousness went wrong.

The key diagnosis: fever is the body fighting back

Doctor Yu Jiayan analyzed further: the child’s fever is actually the body resisting — when you’re attacked by cold, the body mobilizes every resource to fight, and that’s why heat appears. If you can’t see the cold underneath and throw cold medicines at every fever, you’ve made a grave error.

💬 Note from Doctor Luo: Doctor Luo Dalun urges parents here: there’s a simple way to judge whether a child’s fever is cold or heat — touch the hands and feet and look at the tongue. If the hands and feet are hot, the body is genuinely hot, the tongue is red, and the tongue surface is dry — that’s heat; a cooling medicine may be appropriate. But if the tongue is pale, with lots of saliva and moisture on it, and the hands and feet are ice-cold, the fever is most likely from cold — the body fighting back. In that case you must warm the interior; you must never clear heat. The late great Doctor Zhao Shaoqin of Beijing University of Chinese Medicine often said: sometimes a gentle flick opens the qi mechanism and the pathogen disperses — he used light, aromatic medicines like huo xiang (patchouli), pei lan (eupatorium), fang feng (ledebouriella), bai zhi (angelica dahurica), and jing jie tan (charred schizonepeta) to open the qi mechanism. But people who don’t understand this throw niu huang (ox bezoar) and An Gong pills at every fever; the cold gets frozen in the interior, and the child immediately falls into a coma — the consciousness goes wrong.

So why was the child’s nose black as soot? Doctor Yu Jiayan explained: dry bound stool in the large intestine. Up above, the cold medicines had frozen things solid; but in the large intestine there was heat and dryness — the lung and the large intestine are interior-exterior paired organs (fei yu da chang xiang biao li). The lung opens into the nose, so the dry heat of the large intestine shows up on the nose. If the lung qi were truly exhausted, there should be drenching sweat and heavy panting. This child, however, had body heat without sweat, a raised chest but no panting, and the tip of his nose was even slightly moist — not at all the picture of scorching dryness. So Doctor Yu Jiayan concluded: it is not exhausted lung qi — it is cold above, dryness below, with the qi passage blocked.

First move: Lizhong Tang warms the stomach and brings up the wrongly given cold medicines

The treatment was now clear: first warm the spleen and stomach. Doctor Yu Jiayan used the Lizhong Tang approach — gan jiang (dried ginger), bai zhu (white atractylodes), fu ling (poria) and the like, to warm the spleen and stomach and get the qi mechanism moving again. He decocted a small cup, poured it into the child’s throat, and — “wa!” — the boy threw it up in a great gush: all those ice-cold medicines given over the previous two days came right back out! The bulge on his chest collapsed at once, and his neck firmed up a little.

💬 Note from Doctor Luo: There was the turning point. The vomiting meant the spleen and stomach had warmed up; the “ice-packed” state had begun to thaw. The pulse still wasn’t coming up and the child was still unconscious, but Doctor Yu Jiayan said: we already have results. He gave more Lizhong Tang; the child gradually warmed, stopped resisting violently, the fever broke, and the symptoms eased bit by bit.

Second move: a single herb, Xuanming powder, opens the dry bound stool of the large intestine

Next he dealt with the intestinal dryness. Doctor Yu Jiayan took one medicine — Xuanming powder (weathered mirabilite, a purgative that opens the bowels) — dissolved it in water alone and gave it three times, aimed precisely at the dry binding in the large intestine.

That night, the child passed a great deal of black stool — the accumulated dregs of long standing. The qi mechanism opened up, and the next morning the boy suddenly said: “I want some wine!” (probably mimicking the adults — the point is, he was asking for food).

💬 Note from Doctor Luo: Note that the child spoke a sentence but was “still not fully conscious” — partly dazed. At this point Doctor Yu Jiayan used his last move — frequent sips of fluid-nourishing herbs: the interior dryness had injured the body fluids, so he gave fluid-nourishing herbs little by little to replenish them. A day later, the child woke up fully, and the illness was cured.

The deep lesson in the third move: the seed of the Warm Disease school

💬 Note from Doctor Luo: Hidden inside this case is a great secret — Doctor Yu Jiayan was one of the originators of the Warm Disease (wen bing) school. Zhang Zhongjing, in treating febrile illnesses, preserved body fluids by “urgent purging to preserve yin” (ji xia cun yin). Doctor Yu Jiayan, however, “after purging, nourishes yin” — using fluid-nourishing herbs to restore what was lost. That step already carried the flavor of Warm Disease treatment. He left many formulas and ideas in this direction, which is why later generations count him among the pioneers of the Warm Disease school.

Doctor Luo’s summary: these are all good medicines — but only when prescribed for the right pattern

1. Don’t misuse heavy, settling, heat-clearing medicines. Niu huang (ox bezoar), An Gong pills, and mineral medicines are all good medicines — for someone with phlegm-heat clouding the orifices and coma, used correctly they save lives. But using them before the disease has reached that stage only makes things worse. The Warm Disease school divides disease into four levels — defense (wei), qi, nutrient (ying), and blood. If the pathogen is still at the wei or qi level and you go straight to cold medicines that clear the nutrient and blood levels, you might as well open the front door and invite the external pathogen in to fight. When dampness is heavy, you need light, aromatic medicines to open the qi mechanism — not cold, freezing medicines.

2. “Fright wind” must be differentiated; don’t abuse the label. Doctor Yu Jiayan was blunt — he called the term “fright wind” an “empty invention” of earlier physicians that had harmed countless children. That’s a bit extreme: acute fright wind and chronic fright wind do exist. What he opposed was slapping the fright-wind label on every case and immediately reaching for heavy settling medicines. To be fair, Qian Yi, the founder of pediatrics (creator of Liuwei Dihuang Wan), was remarkable — but some of his formulas contained mineral and mildly toxic substances that were gradually phased out as Chinese medicine developed. We should look at this objectively. Doctor Yu Jiayan said that in his youth he argued about this with local pediatricians; later he read Fang Youzhi’s Shang Han Lun Tiao Bian (Systematized Notes on the Treatise on Cold Damage) and its appended Jing Shu chapter, found its views matched his own, and sighed with satisfaction: “I am not alone on the Way.”

3. When a child has a fever, first tell cold from heat, then give medicine. A cold-induced fever often comes with cold hands and feet, a pale tongue with a moist coat; a genuine heat fever comes with hot hands and feet, a red tongue, dry coating. Get the direction wrong and a small illness becomes a big one — exactly what happened in this case: a minor problem was “ice-packed” into a coma by cold medicines, and it took Doctor Yu Jiayan’s step-by-step corrections to pull the child back.

💬 Note from Doctor Luo: One last word: Chinese herbs are all good medicines, but every good medicine is right only for its matching pattern — they are not health supplements anyone can pop at any season. Medicines like An Gong Niu Huang Wan save lives when used correctly and kill when used backwards — remember the child in this case: he is the best warning of all.
