Pomegranate Rind: an Ancient Diarrhea Remedy — Doctor Luo Dalun on What to Do When Your Child Has Diarrhea in Autumn

Opening: pomegranates are everywhere on the streets — today’s herb is exactly that

Not long ago, pomegranates were everywhere on the streets — this is exactly pomegranate season. Doctor Luo Dalun says: since it’s the season, let me introduce a very special medicinal herb.

💬 Note from Doctor Luo: Dear parents, hello everyone. Today we’re going to introduce another herb — what herb? Pomegranate rind. Ah, pomegranates are in season right now, right? A few days ago I saw the streets full of pomegranate sellers.

How pomegranates changed: they used to be sour, now they’re sweet

The pomegranates you buy today are no longer the same fruit they used to be.

💬 Note from Doctor Luo: The pomegranate has been bred and improved. The old Chinese pomegranate was quite sour. Today’s pomegranates are bigger, and the flavor is sweeter. If you happen to find a slightly sour one — that’s fine, I think it’s especially good.

And what good is the pomegranate itself? It is extremely nutritious.

💬 Note from Doctor Luo: What does pomegranate do? Actually, pomegranate is very rich in nutrition. The juice — you can eat one often, it’s highly nutritious. Even abroad, people consider the pomegranate one of the most nutritious fruits you can find.

Chinese medicine doesn’t use the flesh — it uses the rind

We enjoy the fruit with gusto, yet when Chinese medicine treats illness, it deliberately passes over that nutritious flesh.

💬 Note from Doctor Luo: In Chinese medicine we don’t use the flesh inside the pomegranate to treat disease. What do we use? The rind. What does pomegranate rind do? It has detoxifying and astringent (shou se) actions, and its main use is to treat diarrhea.

An old formula from the Song dynasty: aged pomegranate rind

Using pomegranate rind for diarrhea is not a modern invention — this formula existed as early as the Song dynasty.

💬 Note from Doctor Luo: This kind of formula actually appeared in China very, very early — in the Song dynasty there was already such a formula. What is it? Aged pomegranate rind (chen shi liu pi) — that is, pomegranate rind that has been kept for a long time. Friends, pomegranate rind is not afraid of storage. I suggest that when you buy pomegranates, you peel them — eat the flesh inside, and dry the rind in the sun, then store it. Don’t throw the rind away — keep it. Once it’s dried, the drier it gets, the more it becomes like aged tangerine peel (chen pi). That’s what we call chen shi liu pi.

Parents, now you understand: next time you eat a pomegranate, don’t throw the rind away — dry it and store it. The drier the better, just like chen pi. That is your “aged pomegranate rind.”

How to use it? A few grams, boiled in water or cooked into porridge

Once you’ve saved up some aged pomegranate rind, how do you give it to your child?

💬 Note from Doctor Luo: When you use it, here’s how. Take just a few grams — say three to six grams — crush it into small pieces, then boil it in water to drink, or cook it into porridge. What does it do? It has an astringent action, and it can treat diarrhea.

Why do children get diarrhea so easily in autumn?

We’ve all noticed it: when autumn arrives, more and more children around us start having diarrhea. That’s not your imagination — Doctor Luo Dalun explains the whole chain of reasoning.

💬 Note from Doctor Luo: You know, in autumn, children are especially prone to diarrhea. Why? Because the weather in autumn is different from usual. In autumn the weather turns cold, and children easily catch a chill. Once they catch a chill, external pathogens (wai xie) easily invade. Why is that? Under normal conditions your spleen and stomach (pi wei) are warm and functioning normally. So when external pathogens come — say you eat some food that isn’t perfectly clean — almost all food carries some bacteria; there is no such thing as perfectly pure food. If your food has a little bacteria on it, it’s usually no problem — a healthy body can digest it and kill it off, because your spleen and stomach function normally.

So that’s the story: the few bacteria in everyday food are nothing to a person with a healthy spleen and stomach — they’re digested and destroyed without a second thought. But when autumn changes the weather, the situation is different.

💬 Note from Doctor Luo: But when the temperature drops and your spleen and stomach’s yang qi is no longer flourishing, their function declines. Then the environment inside the spleen and stomach changes. In adults, sometimes you can see the stomach mucosa turn pale — why? Because yang qi is insufficient and cold-dampness (han shi) is heavy, so the whole function is low — it’s not congested, it’s the opposite. In this condition, external pathogens easily multiply. You casually eat something that has been sitting out — a few hours, a day — normally you’d be fine, but now, when you eat it, the bacteria and viruses in it multiply easily. So diarrhea easily develops. That’s why when autumn turns cold, weak children get diarrhea — it’s a high-incidence season.

Why autumn diarrhea is the hardest to treat — antibiotics are cold

Autumn diarrhea can sometimes be severe. Parents habitually reach for “disinfection and killing” — antibiotics. In Doctor Luo’s view, that may actually backfire.

💬 Note from Doctor Luo: So do antibiotics work at this point? We disinfect, we kill. But antibiotics are often cold in nature. You can temporarily eliminate the pathogens, but the body gets colder and colder. So taking heat-clearing, toxin-resolving (qing re jie du) remedies at this time often makes the problem more complicated. On one hand you kill the external pathogens; on the other hand you worsen the gut environment even further. And the pathogens are still alive inside, right? So this is exactly why autumn diarrhea is so hard to treat — sometimes even IV antibiotics don’t work.

In one sentence: while killing the external pathogens, you’re making the “room” colder and damper — and the pathogens keep living right in there. That is the root of why autumn diarrhea is so stubborn.

The key point: for external-pathogen diarrhea, astringents are taboo — why is pomegranate rind the exception?

Here is an iron rule of Chinese medicine: for diarrhea caused by external pathogens, astringent anti-diarrheal herbs are strictly avoided.

💬 Note from Doctor Luo: In Chinese medicine, for diarrhea caused by external pathogens, we are especially careful not to use astringent herbs — the anti-diarrheal things, right? If you stop the diarrhea at that point, problems arise: you leave all the pathogens inside, and they multiply in there. That won’t do at all. So generally, Chinese medicine avoids astringent herbs in diarrhea caused by external pathogens.

This is what Chinese medicine calls bi men liu kou — shutting the door and leaving the bandit inside the house.

💬 Note from Doctor Luo: Pomegranate rind has an astringent action. What does astringent mean? It means holding things in place — for example, when you have diarrhea, it holds you back, it stops the water from gushing out. In plain words, it keeps the water from all pouring out of you. That’s the astringent, anti-diarrheal action. But ordinary astringent anti-diarrheal treatment can bring serious consequences — it leaves the pathogens inside. That’s called bi men liu kou. The traditional Chinese medicine saying is: close the door and you’ve left the bandit in the room. That won’t do at all, right?

Yet pomegranate rind is precisely the exception — in one hand it astringes, in the other it detoxifies.

💬 Note from Doctor Luo: And what else does pomegranate rind do? It also has a detoxifying action. That is, it helps you astringe, and at the same time it helps you eliminate those external pathogens. This is pomegranate rind’s very special quality. So when Chinese medicine treats autumn diarrhea, there is often one herb — pomegranate rind — added into the formula. This is its special use.

Close the door, and at the same time destroy the bandits inside the room — that is pomegranate rind’s unique talent. So when Chinese medicine treats autumn diarrhea, the formula often includes exactly this one herb.

What if the child is already sick and nothing works? — pomegranate rind porridge

And what if the child is already having diarrhea — antibiotics don’t work, berberine (huang lian su) doesn’t work, heat-clearing and detoxifying remedies don’t work? Doctor Luo offers a food remedy that is simple and practical.

💬 Note from Doctor Luo: If the child is still having diarrhea — the antibiotics don’t work, the berberine doesn’t work, the detoxifying remedies don’t work — what should you do then? My suggestion is you can drink pomegranate rind porridge. Use a few grams of pomegranate rind — aged rind. Can you use fresh? Fresh is of course fine, but the amount should be doubled — why? Because fresh rind contains water. Crush it into small pieces, the finer the better, and cook it together with rice into porridge. When the porridge is done, drink the porridge.

If the child dislikes the taste of the rind, there’s an even easier way:

💬 Note from Doctor Luo: Or, if you think it doesn’t taste good, wrap the pomegranate rind in gauze and cook it with the porridge; once it’s done, take the pouch out and let the child drink the porridge. This porridge has a wonderfully nourishing, regulating effect on a child’s diarrhea.

Fresh rind works too, but use double the amount — because fresh rind holds water. A few grams of aged rind, crushed as fine as possible, cooked with rice into porridge; if you don’t want your child to eat the bits, wrap it in gauze, cook it, remove the pouch, and drink the porridge.

Closing: learn this trick and you won’t panic in autumn

This method is simple, practical, and children will accept it. Doctor Luo says: once parents learn this, you’ll have confidence this season.

💬 Note from Doctor Luo: This method — you see, it’s simple and practical, and the child can accept it. So if parents learn this method, then when your child gets diarrhea this season, you won’t panic so much, right? You’ll have one more tool in your box. Today we introduced pomegranate rind. Good. Next time we’ll introduce more of these practical little herb tips. After learning them, you can apply them in daily life at any time — and that’s what makes you a qualified parent. Alright, thank you everyone, see you next time.
