A quick apology before we begin
Doctor Luo Dalun opens by picking up where the series left off: how Doctor Zhang Xichun used gan jiang (dried ginger). But first, a short apology — he “skipped class” yesterday. He had felt the previous recording’s audio quality was not quite right, so he took a day off to adjust the equipment. When the episode went up, listeners worried that he must be seriously ill, and a flood of get-well messages arrived.
💬 Note from Doctor Luo: Oh my — nothing that serious at all, I’m fine, truly! Don’t worry, everyone. Today we continue with Doctor Zhang Xichun’s stories. And today’s case, once again, is one that looks so much like a heat condition that you’d want to treat it with cooling herbs — but whatever you do, don’t fall for it.
The patient: a woman in her forties with a stuffed chest, a strange heat, and a terrible wheeze every couple of weeks
The patient was another woman in her forties. Her complaint? Her chest constantly felt full and tight (胸中经常觉得胀闷), and she always felt hot — a dull, stuffy, oppressive heat. And there was a rhythm to it: every ten days or half a month, she would suffer a bout of heavy wheezing for a day or two — wheezing so severe she could hardly bear it.
💬 Note from Doctor Luo: Look at this combination: fullness, heat, and wheezing that comes in episodes. An ordinary doctor takes one look — fullness? That’s blockage, so regulate the qi. Heat? That’s fire, so clear the heat. Up come the qi-regulating, heat-clearing herbs. At first they seemed to work — and then the longer she took them, the worse she got. Finally, with no other option, Doctor Zhang Xichun was called in.
One touch of the pulse: deep, thin, almost gone — and Doctor Zhang Xichun understood
Doctor Zhang Xichun arrived and took her pulse — deep and thin, so faint it could barely be felt (脉沉细，几乎摸不到). He knew at once what was going on: the water-dampness in her body was very heavy.
The patient asked: Doctor Zhang, how did this illness come about?
💬 Note from Doctor Luo: Doctor Zhang Xichun replied: I believe this illness is caused by yang deficiency — and this heat of yours is a false image! You see, earlier in this series we discussed cases where yang deficiency puts on a disguise; here Doctor Zhang Xichun shows us another one. Remember: sometimes the heat you feel in your body is precisely a signal that your yang qi is insufficient.
The mechanism, taken apart: heart-lung yang deficiency, phlegm blocking the clear orifices, and yang qi squeezed out as “heat”
Doctor Zhang Xichun’s analysis was meticulous. The heart and lungs sit in the upper jiao (the upper region of the body). When the yang of the heart and lungs is deficient, it can no longer communicate with and activate the spleen and stomach — and so phlegm grows and dampness accumulates (痰越来越多、湿气越来越重). Heavy dampness breeds phlegm; phlegm then blocks the clear orifices — and with the upper region blocked, you begin to feel fullness and oppression in the chest.
And what happens when the chest stays blocked for a long time? It transforms into “heat.” The qi mechanism cannot move freely; the yang qi is squeezed out and trapped inside — and you feel heat all over your body.
💬 Note from Doctor Luo: In truth this heat is a false image — the yang of the heart and lungs cannot spread through the body, so it gets stuck. That’s why Doctor Zhang Xichun warned that in a severe case the patient would even develop dizziness, blurred vision, and deafness. Notice how today, the moment someone’s ears ring or hearing fades, everyone’s reflex is “tonify the kidneys” — that’s the only idea in the room. But the Inner Canon (《内经》) has a line: “When the nine orifices fail, they all arise from the stomach and intestines” (九窍不利，皆肠胃之所由生). What are the nine orifices? The eyes, the nostrils, the mouth and throat, and the ears. The saying means that disorders of the nine orifices have a great deal to do with the spleen and stomach losing harmony. When the spleen and stomach are out of balance, when dampness is heavy, when heart yang is insufficient — phlegm clouds the clear orifices, and dizziness, deafness, and ringing in the ears all follow. That is the root cause of the illness.
Why the cooling herbs made it worse: when the sun’s light fades, the fog rolls in
So why did the earlier doctors’ heat-clearing, qi-regulating formulas make things worse the longer they were taken? Doctor Zhang Xichun explained: the doctors didn’t understand. They saw heat and reached for cold-natured herbs. But the root of this illness is insufficient heart yang — and the more cooling herbs you take, the weaker the heart yang becomes. It’s like the sun’s light growing weaker — of course the fog rolls in. How could the water-dampness not get heavier?
💬 Note from Doctor Luo: Once the dampness grows heavy, the spleen and stomach are trapped, and a vicious cycle begins. This metaphor is wonderfully vivid: yang qi is the sun, water-dampness is the fog. When the sun weakens, the fog rises; once the fog is up, the sun can’t shine through even more. So the more cooling medicine she took, the sicker she became. What to do, then? Doctor Zhang Xichun said: let me write you a prescription.
The prescription, in the spotlight: Li Yin Tang — Ling Gui Zhu Gan Tang plus dried ginger, purpose-built for dampness rushing upward
Doctor Zhang Xichun prescribed Li Yin Tang (理饮汤, Regulating Fluids Decoction) — a formula he loved whenever he was about to use dried ginger in large doses. Its structure: bai zhu (atractylodes) 4 qian (about 12 g), gan jiang (dried ginger) 5 qian (about 15 g), gui zhi (cinnamon twig) 2 qian (about 6 g), zhi gan cao (honey-fried licorice) 2 qian (about 6 g), fu ling (poria) 2 qian (about 6 g).
💬 Note from Doctor Luo: Look closely — what is this formula? It is Zhang Zhongjing’s Ling Gui Zhu Gan Tang (苓桂术甘汤, Poria, Cinnamon Twig, Atractylodes and Licorice Decoction) with dried ginger added on top! What does Ling Gui Zhu Gan Tang treat? Exactly this situation: insufficient yang with dampness (water fluids) rushing upward. It is a very famous formula. Doctor Zhang Xichun then added bai shao (white peony) 2 qian, ju hong (tangerine peel) 1.5 qian, and hou po (magnolia bark) 1.5 qian — to help move the qi and restrain the yin. His worry: the warming herbs might run too hot and send qi rushing upward too violently, so he used bai shao, a cooling herb, to pull things down and hold the heat in check. And Doctor Zhang Xichun also believed bai shao promotes urination — so the formula drains dampness through the urine while it builds up yang at the same time, a two-pronged attack.
One dose, and the heat was gone — she actually felt a little cool
How did the formula work for this woman? After a single dose, the heat in her heart vanished — she actually felt a bit cool (服了一副药，心中的热就去掉了，反而觉得有点凉). The warming power of the dried ginger was calibrated just right.
💬 Note from Doctor Luo: At that point Doctor Zhang Xichun removed the bai shao and had her continue with the rest of the formula for twenty-plus doses. What happened? Her whole chest became free and open — suddenly light and clear (豁然开朗). And that heavy wheezing that had struck every ten days or so? It never came back. This is Doctor Zhang Xichun’s craft at work — his diagnosis was precisely on target.
Doctor Luo’s closing notes: heat does not always mean a heat pattern — put a question mark in your mind
What does this case teach us? When many people have insufficient yang and heavy dampness, the water-dampness pathogen pushes upward (水湿之邪往上顶), producing chest tightness, wheezing, and even body heat. Doctor Zhang Xichun took this kind of fever especially seriously, and he repeated the point again and again: this heat is a false image.
💬 Note from Doctor Luo: Yang qi is tremendously important. Whether in the upper, middle, or lower jiao — whichever region’s yang becomes deficient, trouble follows. This case of Doctor Zhang Xichun’s is about yang deficiency of the heart and lungs in the upper jiao, and what it produced was chest tightness, wheezing, restlessness, and heat. So please: never look at a fever and conclude “heat pattern” on the spot. Put a question mark in your mind first — could this, in fact, be a cold pattern, brought on by yang deficiency with yin pathogens like water and dampness rising upward? If we learn to make this distinction, that is our little step of progress in study.
