Stomach Pain After Overeating and Mixing Cold and Hot Food?
How this Ming-dynasty eater ate — enough to leave even Doctor Luo speechless
Today’s story features Doctor Gong Tingxian — the imperial physician who was honored with the plaque “Number One Doctor of the Medical Forest” by the Prince of Lu and lived to the age of ninety-seven. Why does Doctor Luo keep coming back to him? Because the patients of Doctor Gong’s era look remarkably like us modern people. When life gets comfortable, all the greed and craving in human nature bubbles up — people want to gorge on everything delicious. The protagonist of today’s case was the extreme example of that.
💬 Note from Doctor Luo: Doctor Gong Tingxian’s case records are wonderfully detailed — he tells you exactly who the patient was and what caused the illness. This one is all about diet.
After marital exertion: a dozen persimmons, cold water, then hot noodles
This patient’s trouble began after marital exertion. Intimacy mobilizes a huge amount of the body’s energy, and afterward a person is naturally a little depleted — that’s exactly when you should rest. Not this fellow. After marital exertion, he wolfed down a dozen or more red persimmons in one go; thirsty from that, he gulped down several bowls of cold water; and before long, he ate several more bowls of hot noodles.
💬 Note from Doctor Luo: Some people say marital intimacy is no big deal — Westerners sometimes claim it costs you nothing. That’s not possible. In animals, mating mobilizes a large amount of energy; a person genuinely does feel a bit weaker afterward, though a good sleep and some rest restores you. The problem here is that this man didn’t rest — he went straight back to gorging. When the body’s functions were at their weakest, he dumped all this food in at once. Of course something went wrong. And honestly — what an appetite! I couldn’t eat a dozen persimmons, then two bowls of water, and then still manage noodles. But this man added several bowls of hot noodles, and then came violent pain in the heart and belly! He was clearly someone who could really push his body around, and this was no way to eat. With eating like that, who else was going to get sick but him?
“Cold and heat locked in combat” — Doctor Gong’s four-character diagnosis
The family rushed Doctor Gong in. He took the pulse: the six pulses were deep and faint, but the qi opening (the right guan position, which reflects the stomach and spleen) was tight and large. Doctor Gong understood at once — the qi opening governs the spleen and stomach; a large qi opening means food stagnation: something was stuck in the stomach.
One more question about how it all started, and the diagnosis was complete. He said: “This is caused by cold and heat locked in combat.” — Your cold and your heat got tangled up together inside the spleen and stomach, and that’s what produced this violent illness.
💬 Note from Doctor Luo: Why were the pulses deep and faint? After marital exertion, the upright qi was already insufficient. Then all this food flooded in at once — cold, hot, hard — and the spleen and stomach simply couldn’t process it. Everything piled up inside, cold and heat went to war, and of course it hurt.
The prescription: warm it, dissolve it, move the qi
Doctor Gong’s strategy was to rescue the cold first. The patient’s pain had actually gotten worse after the hot noodles — which told him the main problem was cold injury: those bowls of cold water had wounded the yang qi of the spleen and stomach. So he used fuzi (aconite), ganjiang (dried ginger) and rougui (cinnamon bark) — all strongly warming herbs — to heat the spleen and stomach back up.
But warming alone wasn’t enough, because the stomach was still stuffed with food. So he added shanzha (hawthorn berry) and shenqu (medicated leaven) — to dissolve food stagnation and push the accumulation downward bit by bit; xiangfu (cyperus) to move the qi; and ezhu (zedoary) to break up the stuck mass — that clump of food needed something strong to split it open.
💬 Note from Doctor Luo: This is a fixed method: if the spleen and stomach have been chilled, warm them; if there’s too much food piled up, immediately add digestion-promoting herbs. Much of what we call “spleen-stomach disharmony” is really eating too much of cold and hot things mixed together, leaving a blockage inside. If it’s meat stuck in there, use shanzha, shenqu and maiya (sprouted barley) to dissolve it, while adjusting to the cold-heat picture — more cold, add some ganjiang, fuzi and rougui to warm things. Combine them like this and the effect is usually immediate.
And the result? One dose stopped it. After a single dose of the medicine, the violent pain stopped.
One dose stopped the pain — then the whole body ran hot: one dose of Minor Bupleurum Decoction
The pain was gone, but now the patient’s whole body started running a fever. Doctor Gong prescribed Xiao Chai Hu Tang (Minor Bupleurum Decoction) — one dose settled it. After one dose the fever broke and the patient was completely well.
💬 Note from Doctor Luo: Why the fever? When food stagnation gets severe, it produces fever and headache, which looks almost like an external invasion. That’s exactly when Minor Bupleurum Decoction comes in — it’s the great “harmonizing” formula: chaihu (bupleurum) disperses outward, banxia (pinellia) sends things downward, huangqin (scutellaria) clears internal heat, renshen (ginseng) builds upright qi — up and down, left and right, cold and heat, it adjusts everything at once. One dose, the qi opens up, and the illness is done.
Why is this patient so much like us?
Doctor Luo is struck by the parallel: in Doctor Gong’s day the Ming dynasty was comparatively prosperous, ordinary people lived well, and those with means could eat whatever they fancied — the disease of binge eating looked exactly like his era, and it looks exactly like ours today.
💬 Note from Doctor Luo: The other day I saw a news story — a woman invited people over for crabs, and she herself ate a dozen or more. She ended up with terrible belly pain, went to the hospital, and it was acute pancreatitis. She nearly died — they rescued her in the ICU! That’s binge eating. This way of eating is terribly hard on the spleen and stomach, yet so many people just follow their whims and gorge on whatever they love.
Doctor Gong’s dietary wisdom: bland flavors keep the spirit clear
Doctor Gong wrote about diet at length in his books. His advice: flavors should be bland — keep the taste light, and the spirit stays clear and the qi stays fresh; that’s a good thing. Overpowering flavors harm the five organs:
- Too much sour harms the spleen
- Too much salty harms the heart
- Too much bitter harms the lungs
- Too much sweet harms the kidneys
- Too much pungent harms the liver
And above all, raw, cold and hard foods are the worst thing for the spleen and stomach.
💬 Note from Doctor Luo: Look at restaurant food these days — the chef ladles in MSG and seasonings by the scoop, and you think it tastes amazing. But that just drives your craving for rich food higher and higher, until you can no longer enjoy the naturally sweet, mild flavor of ordinary food. Every day you agonize: this place has no flavor, that place has no flavor — you only crave the place that dumps in the most seasoning. That isn’t enjoyment. That’s harming yourself!
The spleen loves stillness
Doctor Gong also taught a great principle: the spleen belongs to yin, the stomach belongs to yang. Within yin, “in stillness the spirit is stored; in agitation it is lost” — the spleen is an organ that loves quiet. If you double your portions and force the spleen and stomach to work double shifts, you wound them.
So food must be governed by restraint: eat until satisfied and well, keep qi and blood harmonious, keep the stomach and intestines at peace, and a person lives long; but if you greedily stuff yourself, you overeat, food blocks up inside and fails to digest, the earth qi is damaged, the body is quietly wounded, and eventually all kinds of illness come calling.
💬 Note from Doctor Luo: Doctor Gong’s own words were — “Restrain the food that satisfies you; spare the flavors that delight you.” When you see food you’re delighted by, restrain yourself; when you taste something wonderfully rich, hold back a little. Then no meal wounds you; every meal becomes something beneficial, transformed into qi and blood. Essence stays guarded within, defensive qi stands firm without, and evil toxins cannot strike. Why is it that when external evil arrives, you’re the first to fall? Because the inside collapsed first — the upright qi inside is insufficient and qi and blood don’t circulate properly, and a large part of that traces back to an unregulated diet. The seven emotions wounding internally, and diet and fatigue, are the causes of internal injury diseases — and diet matters most of all, because you eat three meals a day, every single day.
The Huangdi Neijing (Yellow Emperor’s Classic of Internal Medicine) says it well: “When diet doubles itself, the spleen and stomach are wounded.” The words of the sages, passed down to teach ten thousand generations — this is the great law of health preservation.
Ice water plus hot noodles is not “neutralizing” — it’s double damage
Doctor Luo used this case to dismantle a very widespread misconception: people say — if I drink ice water and then some boiling hot water, don’t they neutralize into warm water?
💬 Note from Doctor Luo: That idea is bizarre. Do you think your stomach is a glass bottle? The ice water goes down, and the stomach takes a cold injury; then the hot water goes down, and the esophagus and stomach get hit with heat stimulation all over again — this is double injury, not neutralization at all! I’ve also met people who say “let me add some sugar to neutralize the saltiness,” or “add sugar to balance out the vinegar” — none of that is neutralizing; all of it makes the body miserable on both sides. Whether your stomach survives all this depends entirely on how strong your body is. This patient, bounced between cold water and hot noodles, left his spleen and stomach with no idea what to do — so they simply went on strike. Pain!
Food stagnation 101: Doctor Gong’s diagnostic guide
Doctor Gong had a systematic teaching on food stagnation (shang shi). Food stagnation means eating too much — too much food, too many meals — so the spleen and stomach can’t process it, and the food sits trapped in the chest and belly. The symptoms:
Fullness and nausea — blocked up and queasy; aversion to food — no desire to eat anything; belching and acid regurgitation — burping up sourness; loose stools and foul gas — diarrhea and stinky farts; or abdominal pain with vomiting and diarrhea; in severe cases, fever and headache.
💬 Note from Doctor Luo: The pulse of food stagnation has a distinctive signature: the left guan position is calm and level, while the right guan position is tight, full and large. For treatment, in the early stage when the food has just blocked up, one good vomit cures it — bring it up and it’s over. But if it’s been sitting there for days without resolving, and the stagnation is deep, then you have to dissolve and guide it out gradually. In this case, Doctor Gong warmed and dissolved and moved the qi all at once — treating both the branch and the root together.
Bonus: the science of persimmons — tannic acid and stomach stones
About those “dozen persimmons” in this case, Doctor Luo offers a special warning.
💬 Note from Doctor Luo: Persimmons contain tannic acid. Eat too many, and the tannic acid combines with minerals and proteins, and it can easily form stones in the stomach — clinically, doctors have seen gastric bezoars as big as a chicken egg! So with persimmons, one taste is enough. Never eat them together with high-protein foods (like crab), and certainly never wolf down a dozen in a row. If something truly blocks up in there and forms a stone-like mass, then you’d need all the digestion-dissolving herbs — shanzha, shenqu, jiao shanzha (charred hawthorn) — at once.
Children show the truth fastest
Why take diet so seriously? Doctor Luo says you see it most clearly in children: adults’ overeating shows up slowly; in children the effect is immediate — overfeed a child, wound the spleen and stomach, and the very next day comes a cold, a fever, swollen tonsils. It’s remarkably accurate.
💬 Note from Doctor Luo: Watch children and you’ll understand that we adults are all being wounded too — we just have stronger compensatory ability and slower reactions. But the damage is real. I speak from experience: on days when I’ve eaten something that didn’t agree with me and my stomach feels off, I brew up a couple of packets of hawthorn paste in water and drink it — the discomfort lifts within a short while. That tells you the food was stuck in there and the spleen was weak. So first, restraint: don’t eat too much. Second, if you really have overeaten, use something that dissolves food stagnation to work it out — the discomfort disappears right away.
What to take away: health lives in the small details
This case looks small, but the lesson inside is not. Doctor Gong stopped violent pain with one dose of medicine and finished the job with one dose of Minor Bupleurum Decoction — his skill was genuinely brilliant. But what he really wanted to tell the world is contained in one word: restraint.
💬 Note from Doctor Luo: In this era, nobody dies of starvation — everyone is being overstuffed. More than ninety percent of diet-related illness is from overeating! Exactly like the Ming dynasty. So the greatest good we can do for ourselves at the table is restraint: however delicious the food is, hold back a little, and it can only do you good. Today’s main task is restraint — when you see something spicy and heavy, dip it in a glass of water before eating. It will do you good.
Major illness is built up bit by bit from small disharmonies — the seven emotions wounding internally, unregulated diet and fatigue, all quietly accumulating. Tend to the details, and you won’t end up with a catastrophe. From today, eat well, and know restraint — that is the greatest kindness you can show your spleen and stomach.
