Why Does My Child’s Nose Sweat and the Middle of the Tongue Coating Look Thick? Doctor Luo Dalun: It’s Usually Food Stagnation — Jiao San Xian Can Clear It

💬 Note from Doctor Luo: Hello, parents. Today we continue analyzing children’s tongue photos. This parent asks: the child is 12 years old — why does he always have stomach pain? And his nose tip sweats easily.

Opening: a 12-year-old who keeps complaining of stomach pain, with a sweaty nose tip

A parent of a 12-year-old sent in a tongue photo asking for help: the child always has stomach pain, and the nose tip sweats very easily. Stomach pain is easy to understand — but what does a sweaty nose tip mean?

💬 Note from Doctor Luo: There’s an important point here — what does the nose represent? Let me tell you: the nose represents the spleen and stomach, especially the nose tip. If the nose tip sweats, it means there is either heat inside, or stagnation — because the middle jiao’s qi movement is blocked and congested, so fluids cannot circulate properly and tend to leak out. So a sweaty nose tip means there is either heat or blockage inside.

A map of the tongue: all five viscera and six bowels are written on it

Now look at the tongue photo. This child’s tongue coating covers the whole tongue. What is the biggest feature?

💬 Note from Doctor Luo: This child’s tongue has a slightly thicker coating in the middle. A normal person’s coating is thin in front and thick at the back — a thicker coating at the tongue root is normal. Don’t think, “Oh no, is something wrong with me?” It’s not a problem; everyone is like that. But a thick coating in the MIDDLE — that is a problem.

Why is a thick middle a problem? Because the tongue is a map of the five viscera:

💬 Note from Doctor Luo: The tongue tip corresponds to the heart; the area between the tip and the middle represents the lungs; the left side of the tongue represents the liver, the right side the gallbladder; the root represents the kidneys and the lower-jiao large intestine; and the MIDDLE of the tongue corresponds to the spleen and stomach. A thick middle coating means one very simple thing — this child has food stagnation (ji shi).

What is food stagnation? It’s the spleen and stomach getting “over-stuffed and injured”

When we talk about food stagnation, many parents have heard the term but may not know exactly what it means.

💬 Note from Doctor Luo: What is food stagnation? It’s when we eat too much of one particular thing — beyond what the spleen and stomach can handle — and as a result their function gets injured. That’s food stagnation. For example, a child eats rice cakes — a few at a time — and afterwards doesn’t want to eat anything: that’s food stagnation; it’s blocked inside.

Besides rice cakes, all other foods can cause food stagnation. And the No. 1 cause of food stagnation in children today is eating meat:

💬 Note from Doctor Luo: A child loves braised pork ribs. Grandma and Grandpa see this and think — he loves them so much, let’s make more! So they make more. The child overeats and gets food stagnation. What’s the main reaction after stagnation? The tongue coating thickens — especially the coating in the middle of the tongue.

What signals does a child with food stagnation show?

Besides a thicker tongue coating, children with food stagnation show a string of “smell and feel” signals.

💬 Note from Doctor Luo: At the same time, the child will also have bad breath, bloating after eating, stools that smell stronger than usual; the skin reacts easily when scratched — red patches, bumps, and so on. But the most important sign is still the tongue — if there’s a thick coating in the middle of the tongue, I judge it food stagnation.

Drinking congee every day — does that dissolve the stagnation?

Some parents ask: I give my child congee every day now — the stagnation should be dissolving, right? Doctor Luo’s answer surprised many parents.

💬 Note from Doctor Luo: The food accumulated before may not have dissolved at all. Because once the spleen and stomach have been injured — even though the food itself has moved on — the spleen and stomach are damaged, and we still call this state food stagnation. This state is very likely a change in the gastric mucosa structure, or a change in the stomach’s internal environment — no matter how Western medicine tests it, Chinese medicine regards it as food stagnation. We have seen too many children’s illnesses caused by food stagnation.

Children with food stagnation get fevers: a real case

Food stagnation may sound like just “eating too much,” but the trouble it causes is far more serious than you’d imagine. Doctor Luo told a real case he saw on television.

💬 Note from Doctor Luo: Some children run fevers. I once saw on TV: a child had a high fever for many days — Western medicine used hormones, used antibiotics, nothing worked. Finally they saw a Chinese medicine doctor, who took one look — food stagnation! He gave Jiao San Xian and similar herbs — and the medicine worked immediately. The fever broke the next day. Things like this happen all the time in real life.

That’s why every experienced pediatric Chinese medicine doctor, when seeing a child with a cold, first asks: what did the child overeat before the cold?

💬 Note from Doctor Luo: It’s often a matter of eating too much of something — too much birthday cake, too much meat, too much shrimp. After overeating, the spleen and stomach function is disrupted. Once the spleen and stomach malfunction, qi and blood transformation and the entire operation of the body go wrong.

The spleen-stomach is the mother of the lungs: how does food stagnation drag down the respiratory system?

Why does damaging the spleen and stomach eventually lead to exterior-contraction illnesses and fever? The reasoning here is one of the most classic links in Chinese five-element theory.

💬 Note from Doctor Luo: The spleen and stomach are the mother of the lungs — the spleen-stomach belongs to Earth, the lungs belong to Metal, and Earth generates Metal. When the mother has problems, of course the child has problems. So when the lungs are affected — the respiratory system is affected — exterior pathogens invade easily.

Doctor Luo’s view: behind almost every childhood exterior-contraction illness, there may be a shadow of spleen-stomach disharmony

Putting all this together, Doctor Luo offers a judgment that every parent should write down.

💬 Note from Doctor Luo: In my view, behind almost every childhood exterior-contraction illness, there may be a shadow of spleen-stomach disharmony. It must be that upright qi is insufficient, allowing exterior pathogens to invade. And what causes insufficient upright qi? For children, it’s basically eating wrongly and eating badly — leading to food stagnation. This kind of food stagnation is extraordinarily common among children.

So parents should learn to read the tongue: whenever the coating thickens — sometimes the whole coating is thick, meaning more severe stagnation; sometimes only the middle thickens, which is also classic food stagnation.

How to clear food stagnation? Jiao San Xian, 6 g each, decocted in water and drunk

Once you’ve identified food stagnation, the question is what to do. Doctor Luo gave a simple, practical little formula.

💬 Note from Doctor Luo: What to do about food stagnation? You can use Jiao San Xian — 6 g of each, decocted in water and drunk. Jiao San Xian is charred hawthorn berry (jiao shan zha), charred medicated leaven (jiao shen qu) and charred barley sprout (jiao mai ya) — three herbs. Just ask for “Jiao San Xian” at any herbal pharmacy and they’ll know.

Doctor Luo’s promise: he is developing a food to clear food stagnation for children

After the formula, Doctor Luo also revealed a “big project” in progress — he wants to solve the food stagnation problem at the food level, helping parents from the kitchen.

💬 Note from Doctor Luo: I am currently partnering with a company in Benxi, near Shenyang — Dashi Pharmaceutical. This is an excellent company; it exports Chinese medicine exclusively abroad — to Germany, the United States, Korea and so on. All its exported Chinese medicines meet international standards — German standards, no problem at all — with no heavy metal residue, no pesticide residue, no chemical fertilizer residue. I asked them: can you produce a food for children that clears food stagnation and strengthens the spleen and stomach — an actual food, not a health supplement? They agreed, and now they’re using international pharmaceutical standards to make this children’s food. When it’s on the market, I’ll let everyone know.

Closing

💬 Note from Doctor Luo: But parents must learn for themselves — later we’ll introduce more knowledge about children’s food stagnation: how to prevent it, how to clear it. All right? Thank you, everyone. See you next time.

What to take away

Doctor Luo’s central message in this lecture is one sentence every parent should remember: behind almost every childhood cold or fever, there may be a shadow of spleen-stomach disharmony — and for children, that usually means food stagnation.

The nose, especially the nose tip, represents the spleen and stomach. A sweaty nose tip means the middle jiao is blocked — heat or stagnation inside, fluids not circulating properly.
The tongue is a map of the five viscera: tip = heart, tip-to-middle = lungs, left = liver, right = gallbladder, root = kidneys and lower-jiao large intestine, middle = spleen and stomach.
A thick coating at the tongue root is normal (thin in front, thick at the back is the healthy pattern) — but a thick coating in the MIDDLE of the tongue is a reliable sign of food stagnation.
Food stagnation = eating too much of one thing, overloading the spleen and stomach — rice cakes, braised ribs, birthday cake, shrimp, and above all too much meat in today’s children.
Other signals: bad breath, bloating, strong-smelling stools, skin that reddens and bumps when scratched.
Drinking congee doesn’t automatically dissolve old stagnation — once the spleen and stomach are injured, the state can persist (possibly a change in gastric mucosa or stomach environment).
Why stagnation leads to colds and fevers: the spleen-stomach (Earth) is the mother of the lungs (Metal); Earth generates Metal, so when the mother is ill the child suffers — the respiratory system weakens and exterior pathogens invade.
Treatment: Jiao San Xian (charred hawthorn berry, charred medicated leaven, charred barley sprout) — 6 g of each, decocted in water and drunk. Ask for “Jiao San Xian” at any herbal pharmacy.
A real case: a child with a multi-day high fever that Western antibiotics and hormones couldn’t break — a Chinese medicine doctor saw food stagnation, gave Jiao San Xian, and the fever broke the next day.
Doctor Luo is also developing a children’s food to clear stagnation and strengthen the spleen and stomach with an export-grade pharmaceutical company (Dashi Pharmaceutical, Benxi), made to German and American standards — he will announce when it launches.
