Wearing a Cotton Coat in Summer and Still Freezing? Doctor Wang Mengying’s Bitter-Cold Herbs for True Heat with False Cold
Patient search terms: feeling cold / wearing thick clothes in summer / freezing even in a cotton coat / always feeling cold / grayish-green face / impotence / heavy breath odor Medical terms: true heat with false cold (zhen re jia han) · deep internal heat accumulation · stagnation of qi movement (extreme heat generating cold, the qi mechanism blocked and unable to reach the surface)
The opening: a man who was ruined by one hundred and thirteen doctors
Today we continue the case stories of the great Qing-dynasty physician Doctor Wang Mengying. And today’s patient is one of his old friends — Zhang Yangzhi. His story is remarkable, and he is a recurring figure in Doctor Wang’s case records — many members of Zhang Yangzhi’s family and household were treated by Doctor Wang over the years.
Zhang Yangzhi’s life was genuinely hard-luck. At twenty (the age of ruo guan, coming of age) he lost his father, and then fell ill with a mysterious disease — the records don’t say what it was, only that it dragged on for seven full years. Those seven years drained the family’s money completely. How many doctors did he consult? The record is precise: one hundred and thirteen physicians in all. One hundred and thirteen doctors — and not one of them could cure him.
💬 Note from Doctor Luo: Seven years, one hundred and thirteen doctors, and the illness never improved — that tells you something about the level of Jiangnan medicine at the time. But this still happens today. Patients write to me all the time saying, “I’ve seen every Chinese medicine doctor there is,” they’ve been to hospital after hospital, and the illness just won’t heal. This situation exists in every era.
Who was the patient? He taught himself Chinese medicine and cured himself — but his nose was ruined
What did Zhang Yangzhi do next? He “bought medical books” — he purchased Chinese medicine texts, studied them quietly at home, and taught himself the art. He became a devoted student of Chinese medicine, studying every day and treating himself. And guess what? He actually cured himself! But by then his nose was already ruined — presumably the illness had been so severe that his nose had become deformed, and it could never grow back.
💬 Note from Doctor Luo: Think of Huang Yuanyu — the famous Qing-dynasty physician whose eye was blinded by a quack doctor. Here, Zhang Yangzhi lost his nose. Under Qing-dynasty law, a man with an incomplete or disfigured face could not sit the imperial examinations. With a facial defect, a scholar’s whole future was basically finished. So Zhang Yangzhi, “bearing this injustice he could not speak of, ashamed of his own appearance,” stopped going out altogether and closed his door to practice calligraphy — he stayed home perfecting his brushwork, planning to earn a little money by selling his writing.
Meeting Doctor Wang Mengying: two layers of clothing in summer, and still cold
Later, Zhang Yangzhi met Doctor Wang Mengying, and the two became bosom friends (mo ni zhi jiao). When Doctor Wang looked at this fellow, he saw: a grayish-green face, a body that seemed very weak, prone to external attacks — catching colds at the slightest thing; wearing thick clothes even in summer — in summer the rest of us wear a tank top, but he would put on an extra layer, two layers in all; and he constantly spat white foamy phlegm — not yellow phlegm, but white foam. And when asked, it came out: impotence for many years. Now, impotence of many years — most people would instantly think kidney yang deficiency, right?
Zhang Yangzhi thought so too, which is why he had been taking warming, tonifying herbs for years — he always felt cold, so he took warming medicines to supplement. Doctor Wang repeatedly urged him: “Stop taking random medicines. Stop taking all these warming tonics.” But people rarely listen — and look at the man’s condition: grayish face, fear of cold, extra clothes in summer, spitting foam, easy to catch cold. Doesn’t that genuinely look like yang deficiency and insufficient upright qi? Yes, it does.
💬 Note from Doctor Luo: But Doctor Wang had a nagging feeling something was wrong with this picture. And sure enough, in September of that year, trouble erupted.
September onset: sudden chills and headache — his own diaphoretics did nothing
That September (autumn), Zhang Yangzhi suddenly developed aversion to cold and headache — suddenly freezing and a pounding head. He tried some warming, dispersing herbs on his own, the kind that induce sweating — no effect. So Doctor Wang Mengying was called in.
Doctor Wang took his pulse: extremely deep and firm — the pulse was very deep; you had to press all the way down, down to the bone, before you felt something like a taut lute string, smooth and slippery, beating with real strength. Then he looked at Zhang Yangzhi himself. The man was lying in a sealed inner chamber — the room was shielded so no wind could blow directly on him, and heavy curtains were drawn. In Jiangnan in September, before the weather had even turned cold, he had a stove fire burning inside his curtained bed, wrapped in a thick cotton coat, and still felt it wasn’t enough to keep out the cold. And the foam kept coming — spitting without pause; the cough never stopped, bringing up white foam. Was his chest or belly distended? No. His stools were more or less normal, his urine was scanty, and his breath was extremely foul — his mouth had a very strong odor.
The diagnostic highlight: it looked like yang deficiency; Doctor Wang said “extreme heat generates cold”
Here is where real skill shows. Before tongue diagnosis was in common use, this kind of hot/cold call was terribly easy to get wrong — because there are false appearances. Look at the picture: so afraid of cold that he sits behind a stove, wrapped in cotton, spitting foam, face grayish-green — this looks like textbook yang deficiency, doesn’t it? Extremely easy to misdiagnose. In Chinese medicine, a patient’s symptoms are not as simple as the textbooks; there is often falsehood on the surface.
What did Doctor Wang look at? He certainly looked at the tongue. Doctor Luo always teaches the tongue — and the tongue tells the truth here: the tongue body must have been red. Doctor Wang’s verdict: this is extreme heat generating cold — the heat accumulated inside your body is extremely deep; the qi mechanism is blocked and cannot reach the surface, so the heat stays hidden deep inside, obstructing the movement of qi. That is why the four limbs are cold and the whole body shivers — it is all qi failing to move through. The cold is a false appearance; the heat inside is real, and fierce. So what to do? Nothing but heavy bitter-cold herbs to drain it — you must use bitter, cold medicines to drive that heat out.
💬 Note from Doctor Luo: Diagnosis in Chinese medicine is genuinely hard — it looks like yang deficiency, and it turns out to be true heat. Here’s an analogy: a river. When the channel is clear, everything flows and the water level is the same on both banks. But if a rock blocks the middle, you’ll find the water piling up upstream while downstream goes dry. Why is the lower part cold? Because the water can’t get through. People are the same — heat trapped inside, unable to get out, makes the outside feel cold, because the qi mechanism is blocked. I saw exactly this when my own mother had nephritis: she wore a cotton coat in high summer, and anyone would have read it as yang deficiency and warmed her up — that would have been wrong, because her tongue was red! We cooled her blood instead; the blood cooled slowly, circulation returned, the qi mechanism opened up, and she went back to wearing normal clothes — never afraid of cold again. I lived through this, so I’m certain: some people who are freezing cold are actually burning hot inside — the heat is trapped so thoroughly that the channels cannot function, and that is what shows up as cold.
The prescription: heavy bitter-cold herbs to drain heat — Zhang Yangzhi put his life in Doctor Wang’s hands
Doctor Wang wrote out his diagnosis. Zhang Yangzhi hesitated at first: I’m this cold — you’re giving me bitter-cold herbs to drain heat; will that really work? But when he read Doctor Wang’s reasoning — clear, structured, flowing — he cried out: “My life is bound up with the lives of my whole family. Brother, only you can pity me and save me!”
Doctor Wang reassured him: “I am not fooled by the false appearance on the surface. I judge it plainly as true heat accumulating within — this is not guesswork; there is real pulse and symptom evidence to support it.” Rest easy and let yourself be treated; don’t harbor doubts. He then prescribed a heavy formula of bitter-cold herbs — containing fierce heat-draining medicines like mang xiao (Mirabilite, sodium sulfate) and da huang (rhubarb).
The rocky course: no response — and the relatives exploded
The bitter-cold formula was given. After two or three days, the illness had not lessened at all — nothing had changed. Now the relatives and friends began to mutter — the thing doctors fear most: the family chattering, saying the prescription is too fierce, too harsh; Zhang Yangzhi’s body is this weak, how could anyone give him such violent medicine? Someone stepped forward and said they should be more careful. A certain Mr. Yu declared publicly: “Zhang Yangzhi’s life is being handed over to Wang Mengying’s hands!” — this poor man is sure to die at Doctor Wang’s hands. Everyone buzzed with disapproval. The next day, two more physicians were invited — Dr. Chen Qidong and another Dr. Yu — recommended by well-meaning friends: “I know a doctor, let me introduce him.”
When Doctor Wang heard about this, he hurried straight to the sickbed — this is what a true brother does. Most physicians, when the medicine produces no reaction and the family starts bringing in other doctors, simply walk away. Doctor Wang fought for his patient.
💬 Note from Doctor Luo: He went to the bedside and spoke from the heart: “Brother, if you were not my closest friend, then take whatever medicine you like — I would not dare interfere. If your family were wealthy, go ahead, summon famous physicians from far and wide, spend whatever it costs — I would never stand in your way. But you are a poor scholar, and my closest friend. What famous physician could your money actually hire? If these doctors truly recognized your illness and their medicine cured at once, I would be the first to urge you to take it. What I fear is that they cannot recognize this disease at all — they will read it as yang deficiency, and their prescriptions will be nothing like as powerful as mine. They will write some bland, lukewarm formula that offends nobody, cures nothing, and simply wastes your time — that is what would truly ruin you.” He also urged Zhang Yangzhi: save the consultation fees of these two doctors — you’ll need the money for medicine later.
Standing firm: no reaction is precisely proof that the medicine hasn’t reached the disease yet
Doctor Wang also offered an argument of remarkable persuasiveness: “We have now been taking bitter-cold herbs for two or three days. If the prescription were wrong, trouble would already have appeared — if you were truly yang deficient, with your constitution, my bitter-cold herbs, mang xiao and da huang, these violent medicines, would have wrecked you long ago. The fact that nothing has happened tells us exactly what is going on: the heat inside you is so deep that the medicine has not yet truly struck the disease. So we must increase the dose!”
Zhang Yangzhi listened from his pillow and was profoundly moved — because who else would go this far for you? Doctor Wang’s reasoning was unassailable: if you really were yang deficient, the rhubarb and Mirabilite would have done you in already; no reaction means the medicine simply hasn’t reached the disease. So Zhang Yangzhi continued taking the medicine as directed.
💬 Note from Doctor Luo: This is what diagnostic confidence looks like. Without a rock-solid grasp of the case, who could withstand this kind of family pressure? Doctor Wang could pound his chest because he read the tongue and trusted the pulse — true heat with false cold, and the evidence was all there.
The result: glue-like stools, and the cold retreated day by day
After continuing the medicine, two days later, the bowels passed stools like glue — and the smell was enormous. And then the miracle: the chills gradually lessened; the large patches of dry skin became moist; he slowly started drinking congee again, the rice porridge increasing day by day; and after about ten days, the color of his stools returned to normal — this is a crucial sign, because stool color tracks the illness: when there is heat, the color runs dark, and when the color normalizes, the heat has cleared. After a hundred days, he was healthier than before — far better than he had been! From then on, even in the depths of winter he no longer feared the cold; if he caught a slight chill and a minor ailment, a light, cool-moistening formula would set it right. His yang path revived — the long-standing impotence resolved; everything functioned normally again. Later, the family welcomed another daughter — proof that his body had fully recovered.
💬 Note from Doctor Luo: You see — once the internal heat is cleared away with cold medicines, he stopped feeling cold. Why? Because the cold was a false appearance — the cold came from blocked channels. The cold you feel may look like yang deficiency, but it is not yang deficiency. Everyone, remember: being cold all over is not necessarily yang deficiency! Sometimes it is phlegm congealing, qi and blood clotting, blocked and unable to circulate; sometimes it is heat gathered inside, throwing the movement of qi into disorder. My mother, back then, recovered step by step on cooling, blood-cooling herbs — and after she recovered, her body was better than before; she went out and had real energy. This method of Doctor Wang’s, I know it from personal experience.
Epilogue: the technique can be learned; Doctor Wang’s heart cannot
After Zhang Yangzhi recovered, he praised Doctor Wang to others with a line that became famous: “Wang Mengying’s hands — those, perhaps, one could learn; but Wang Mengying’s heart — that, ordinary people cannot reach!” The skill Doctor Wang practices, you can study; but his kindness of heart, most people cannot match. Look at my case: a disease-root hidden for over ten years, swept clean at one stroke — I feel my spirit is stronger than before, and this will be the foundation of my remaining years. This is the grace of my second birth.
💬 Note from Doctor Luo: Doctor Wang Mengying’s level of medical ethics was extremely high — among the famous Qing-dynasty physicians, he absolutely ranks near the top. His character was sharply defined: he treated his patients with wholehearted warmth, and he constantly fought against mediocre doctors. Look at this case — over a hundred doctors had failed. If Doctor Wang had let it slide, if he hadn’t taken it seriously, the illness would never have been cured. Because he took it seriously, he saved the man. Compare that with some doctors today: if a patient knows a little Chinese medicine and uses a technical term, the doctor takes offense — “Whose books have you been reading? Go see him, then.” Doctor Wang was not like that; he genuinely considered the patient’s welfare. I hope the young Chinese medicine practitioners of the future will read Doctor Wang’s case records, learn about his character, and become people like him — responsible toward patients, and committed to pulling them through.
One more note to remember: being afraid of cold does not always mean yang deficiency — women with blood deficiency also feel cold: when the blood is insufficient and cannot spread warmth to the body surface, coldness shows itself. Anything that keeps the body surface from being warmed will appear as fear of cold; this kind of “false yang deficiency” must be treated by solving the root problem. And the key to distinguishing true heat with false cold is — look at the tongue: the tongue body must be red.
