Craving Cold Drinks but Feeling Even More Stuffed? Chest Tightness, Irritability and Dawn Diarrhea — Doctor Zhang Xichun’s Liyin Decoction for Yang Deficiency Behind the False Heat
Opening: a morning in Singapore — let’s keep talking about dried ginger
Doctor Luo Dalun has been giving lectures in Singapore these past two days, and every morning he records a short talk for us. Yesterday he told the case of Doctor Zhang Xichun using dried ginger — the story of Zhang Shoutian. Today, let’s continue. How exactly did Doctor Zhang Xichun use dried ginger to regulate the body? Today’s patient was a woman in her forties, and her illness had a deeply deceptive feature: the heat she felt was actually fake.
💬 Note from Doctor Luo: Everyone, remember today’s theme — “sometimes the heat you feel is actually false heat (xu re).” This is one of Doctor Zhang Xichun’s most important lessons. If you fail to recognize the illusion and head in the wrong direction, the more you treat, the worse the illness becomes.
Who was the patient? In her forties, chest stuffed, mind restless, always craving cold food
This woman was in her forties, and when she came to see the doctor she felt deeply uncomfortable. What were her complaints? Fullness, stuffiness and irritability in the upper body — her chest constantly felt blocked, tight and swollen, and inside she was intensely restless. Strangest of all: she always wanted to eat something cold.
💬 Note from Doctor Luo: Do you see the problem here? Craving cold things, feeling irritable and restless — doesn’t that look like a heat condition? Many people would immediately think: this must be heat! Hold on. In Chinese medicine, patients’ symptoms are full of illusions. Let’s read on.
Eating cold made it worse, and she had diarrhea at dawn — this was no simple illness
Sure enough, here came the problem: whenever she ate something cold, the fullness and stuffiness got worse — even more blocked. Not only that, every morning at dawn she had diarrhea — in Chinese medicine this is called wu geng xie, the “five-watch diarrhea,” also known as dawn diarrhea. This diarrhea had dragged on for a long time without healing, and in the meantime her whole belly slowly began to swell up. When Doctor Zhang Xichun took her pulse: it was wiry, thin and slow (xian xi er chi) — taut and slender like a plucked string, and beating slowly.
💬 Note from Doctor Luo: Friends, once the belly starts to swell, that is never good news — this is a warning sign. A wiry, thin and slow pulse: a slow pulse indicates cold (chi mai zhu han), a wiry and thin pulse indicates fluids gathering (xian xi zhu yin) — and with that, half of the diagnosis was already fixed.
Doctor Zhang Xichun’s diagnosis: cold fluids have all stopped, blocking the transformation of qi
Doctor Zhang Xichun examined her and declared the nature of the illness: cold fluids have all stopped and gathered, blocking the transformation of qi (qi hua). What does that mean? It means that cold, carrying water-dampness with it, has settled in the chest and the middle burner, and as a result qi transformation is obstructed — the movement of qi is blocked, and it is stuck there. That is why she felt stuffy and swollen.
💬 Note from Doctor Luo: Cold fluids parked in the middle, the movement of qi blocked — this is the root of the “stuffiness and swelling.” But then why was this patient restless and craving cold drinks? The theory Doctor Zhang Xichun gives next is the most brilliant stroke of the whole case.
The key theory: when yang qi is insufficient, the qi mechanism stagnates — the heat is an illusion
Doctor Zhang Xichun had a theory: when a person’s yang qi is insufficient, the qi in the chest becomes blocked and stagnant, unable to circulate — and when stagnation builds up, it transforms into heat, so the person feels hot: restless, annoyed, and inclined to want something cold to drink. That heat is an illusion — it is false heat (xu re).
💬 Note from Doctor Luo: Friends, many patients present exactly this way, and some doctors cannot tell whether it is cold or heat. Doctor Zhang Xichun’s experience is crucial: in this situation the yang qi is insufficient, and insufficient yang can produce a false heat — the heat is an illusion! There are people whose yang has been injured and whose body is heavy with dampness, yet they crave cold water; the more they drink, the more uncomfortable they feel — restless, irritable, still craving cold — this is exactly the situation.
The prescription revealed: Liyin Decoction, with 5 qian of dried ginger leading the charge
So what did he do? Doctor Zhang Xichun gave Liyin Decoction (Li Yin Tang) — a famous formula from Records of Chinese Medicine with Reference to Western Medicine: dried ginger (gan jiang) 5 qian, atractylodes (bai zhu) 4 qian, cinnamon twig tips (gui zhi jian), raw white peony (sheng bai shao), poria slices (fu ling pian) and honey-fried licorice (zhi gan cao) 2 qian each, tangerine peel (chen pi) and magnolia bark (hou po) 1.5 qian each.
💬 Note from Doctor Luo: Dried ginger warms the middle and disperses cold; atractylodes strengthens the spleen and dries dampness; cinnamon twig opens the yang and transforms qi; poria promotes urination and drains dampness; white peony nourishes the yin and harmonizes the nutritive level (ying); tangerine peel and magnolia bark regulate qi and disperse distension — together they dissolve the cold-damp parked in the upper and middle burners bit by bit. Once the yang qi flows freely, the stuffiness and swelling naturally dissolve.
The family’s objection: “She wants cold things — how can you give hot medicine?” The dried ginger water test settled it
As soon as the prescription was written, the patient’s family panicked: “She keeps wanting cold things — doesn’t that mean she has heat? How can you give such hot medicine?” — exactly like the family in yesterday’s Zhang Shoutian case. Doctor Zhang Xichun did not argue. He said: “First boil some dried ginger water and let her drink it. See whether she feels comfortable. If it feels good, there is nothing to worry about.”
So the family boiled dried ginger water, and the moment the patient drank it — immediately, the irritability in her chest vanished, and that blocked, stuffed feeling was gone in an instant!
💬 Note from Doctor Luo: This is Doctor Zhang Xichun’s wisdom — he did not argue with the family; he let the medicine speak for itself. The moment the dried ginger went down, the false heat in the chest dissolved at once, proving that this was cold, not heat. The patient and her family were convinced, and from then on the whole household trusted Doctor Zhang Xichun completely.
The modification: for dawn diarrhea he dropped white peony and magnolia bark, and added chicken gizzard lining and psoralea
Because the patient had dawn diarrhea (wu geng xie) — her yang qi was extremely insufficient — Doctor Zhang Xichun removed the magnolia bark and the white peony from the formula: white peony is somewhat cooling, and magnolia bark drives qi downward, neither of which suited her. In their place he added raw chicken gizzard lining (sheng ji nei jin) 1.5 qian and psoralea fruit (bu gu zhi) 3 qian: chicken gizzard lining dissolves stasis and accumulation, and psoralea warms the kidney yang and stops dawn diarrhea. And the result? She took it continuously for ten doses, and all her complaints were cured.
💬 Note from Doctor Luo: Look at this modification — the same Liyin Decoction, but because there was diarrhea he removed the cooling and descending herbs and added herbs that warm the yang and firm up the intestines. The medicine follows the pattern — this is the fine precision of Doctor Zhang Xichun’s prescribing.
Why did she get this illness? Icy drinks and cold-natured medicines had wounded the yang of her chest
What lesson does this case teach us? Doctor Luo Dalun says that many people today have insufficient yang qi — how does insufficiency of yang in the upper and middle burners come about? Constantly drinking iced beverages and regularly taking cold-natured medicines; over the long run the yang of the chest is injured, and the yang of the heart, lungs and stomach is damaged.
💬 Note from Doctor Luo: What happens after the yang is injured? A person becomes distended — a swollen belly, a falsely bloated abdomen, chest tightness, and so on. Some patients prefer warm things and dare not touch anything cold; but other patients feel restless and crave cold drinks — remember, that is the illusion! The more cold you drink at this point, the more you wound your yang, the more distended your belly, the more blocked you feel inside — and then the problem becomes serious.
Dried ginger, aconite and cinnamon each govern their own territory: the channel affinities of warming herbs
So what should be done? Doctor Zhang Xichun’s experience is crucial: the heat is an illusion, and you must use warming medicine to warm the body back up quickly. But choosing the warming herb takes care. He said aconite (fu zi) and cinnamon (rou gui) were not quite suitable, because these two warm the middle and lower burners — especially the lower burner; whereas dried ginger’s action reaches the upper and middle burners. So in treating this kind of illness, Doctor Zhang Xichun used dried ginger for the upper and middle burners, paired it with atractylodes and the rest, and used Liyin Decoction to clear the cold-damp from the upper and middle burners, letting the yang qi move and rise again — and the patient recovered step by step.
💬 Note from Doctor Luo: Doctor Zhang Xichun was extremely particular about the channel affinities of herbs — which herb governs the upper burner, which governs the lower — he drew the lines sharply. For yang deficiency with cold fluids in the upper and middle burners, dried ginger is the first choice, not aconite or cinnamon. Remember this detail.
Doctor Luo Dalun’s reminder: learn to recognize the illusion, don’t get the direction wrong
Finally, Doctor Luo Dalun gives a special warning: we absolutely must learn to recognize this illusion, otherwise we get the direction wrong, and the more cooling medicine we give, the worse things become — this is no small matter. Some people’s bodies collapse from exactly this point; once the yang is wounded, the illness becomes hard to cure. And warming the body takes time: you saw Doctor Zhang Xichun cure other illnesses with one or two doses — medicine arrived and the disease left, two or three doses settled the matter. But this kind of warming took ten doses — the body has to be warmed back up little by little, and you cannot rush it.
💬 Note from Doctor Luo: This is the accumulated experience of Chinese medicine: acute conditions can be cut short with fierce medicine, but the recovery of depleted yang demands slow, gentle nourishing. Today’s case is the best teaching material for “the heat you feel is actually false heat.”
Well, friends, that is all for today. Next time we’ll continue talking about how Doctor Zhang Xichun used dried ginger. Thank you, and goodbye.
