Opening: the old man next door in the nursing home — one bite of food at midnight nearly turned into a catastrophe

The Chinese patent medicine Doctor Luo Dalun wants to discuss today is sold in almost every pharmacy — Mu Xiang Shun Qi Wan (Aucklandia Qi-Ordering Pill). But to explain how to use it properly, he must first tell a true story from his own life.

💬 Note from Doctor Luo: Last year my mother was living in a nursing home — a very nice one right by our house. Next door to my mother lived an elderly couple. One day my mother suddenly told me: “The old couple have been hospitalized. What happened?” It turned out the husband had had intestinal cancer years ago, recovered very well after surgery, and had plenty of hobbies — he even played the piano. So the two of them were living quite comfortably.

The story begins unremarkably — but one night nearly pushed that elderly couple into despair.

Hungry at midnight, he got up and ate something, and his stomach “locked up”

That night the old man woke up hungry in the middle of the night, got up by himself, and took something from the fridge.

💬 Note from Doctor Luo: And then it went terribly wrong. What happened? His stomach started to hurt, then it swelled up — really distended — and he couldn’t eat anything. His spirit instantly collapsed. In the daytime the old lady saw this and thought, no good, we have to get him to the hospital. So they took him to a big hospital near our home and admitted him.

Who could have imagined that a midnight snack would send an elderly man into a major hospital?

In the hospital: every department head was summoned, and no one could say what was wrong

Once admitted, the old man only got worse.

💬 Note from Doctor Luo: In the hospital his belly swelled up enormously. No bowel movement. Couldn’t eat — no appetite at all. His spirits failed, and he lay in bed unable to rise. They started treatment, but after several days nothing worked. Word had it they called in the department heads from every specialty for a consultation — but no one could say what was really going on, what the illness was, or how to treat it. The consultation produced nothing; after several chiefs conferred, there was still no plan. The old man’s condition was very poor: he could not eat, was kept alive on IV fluids, and drifted in and out of consciousness — a state bordering on critical.

Swollen belly, can’t eat, can’t go — and the department heads of every specialty had no answer. Where was the problem?

Leaving the hospital: one phone call recommended Mu Xiang Shun Qi Wan

Since the hospital had no plan, staying meant nothing. The old lady decided to discharge him and asked Doctor Luo’s mother: what does your son think about this?

💬 Note from Doctor Luo: My mother called me and described the whole situation. I said the qi mechanism in his abdomen was blocked — there are roughly two medicines that could work: one is Mu Xiang Shun Qi Wan, and the other is Mu Xiang Bin Lang Wan (Aucklandia and Betel Nut Pill). If you can buy Mu Xiang Shun Qi Wan, it is worth trying. So they bought it and gave it to him — and from the moment it went down, his belly started rumbling audibly, he could have a bowel movement, and the distension began to go down.

The moment the medicine touched his lips, the long-silent intestines finally stirred.

The turnaround: rumble rumble, the bowels opened — and the old man was sitting in the corridor again

After taking Mu Xiang Shun Qi Wan, the turnaround came faster than anyone expected.

💬 Note from Doctor Luo: By the next day the old man was up and could eat a little. He kept taking it, and on the second or third day, when I went to the nursing home, I saw him sitting in the corridor. I even chatted with him a little. He had simply taken this Mu Xiang Shun Qi Wan — and after a few days, he had no problems at all: he was eating normally, his swollen abdomen had gone down and flattened, and his bowels were moving freely. It was all fine. He had recovered.

Later the couple moved back to their hometown — but the gratitude stayed with them.

💬 Note from Doctor Luo: Every time they chat on WeChat, the old lady still brings it up with my mother: “Thank you so much for recommending Mu Xiang Shun Qi Wan back then. Don’t underestimate this little patent medicine — it saved a life! It solved a condition that several department heads, all consulted together, couldn’t figure out.” She said she would never forget it, and was deeply grateful.

Why does a tiny, cheap pill have such power? The secret is right in the name — shun qi: order the qi.

What is this medicine for? — it specializes in “regulating qi”

Mu Xiang Shun Qi Wan is one of the most classic qi-regulating (li qi) formulas in Chinese medicine.

💬 Note from Doctor Luo: Why regulate qi? Because sometimes, for certain reasons — cold-dampness, for example — the spleen and stomach, already weak, get their qi movement blocked. Damp turbidity, cold-dampness, and the like obstruct the middle burner, and the qi mechanism cannot flow, so you get chest and diaphragm distension and oppression, spleen and stomach distension and pain, and below, the belly is bloated and painful.

When the qi mechanism is blocked, what signals does the body send?

💬 Note from Doctor Luo: With qi stuck inside, you may feel nauseated — because the qi is not descending; the stomach qi cannot go down, so sometimes you feel like vomiting. Sometimes the qi rushes upward, and you lose your appetite, because things are blocked inside. And when the blockage is severe, the stools do not pass smoothly either. So when the spleen and stomach develop this kind of qi stagnation — distension, fullness, and pain in the middle — from cold-dampness or similar causes, Mu Xiang Shun Qi Wan can regulate the qi for you, smooth it out, and eliminate the distension. Once the qi mechanism is free, the spleen and stomach recover their function of ascending the clear and descending the turbid, and the body recovers.

Remember this positioning: move qi and resolve dampness, fortify the spleen and harmonize the stomach — it treats spleen-stomach qi stagnation caused by cold-dampness. And why does the formula work? Let’s look at it herb by herb.

Herb No. 1: Mu Xiang — the number-one qi regulator in Chinese medicine

The formula is called “Mu Xiang Shun Qi Wan,” so naturally the lead herb is mu xiang (Aucklandia root).

💬 Note from Doctor Luo: Mu xiang is a very famous qi-regulating herb in Chinese medicine, with the actions of moving qi to stop pain and warming the middle to harmonize the stomach. Its nature is warm — pungent, bitter, warm — and it enters the lung, liver, and spleen channels. You must understand: this kind of qi stagnation is almost always connected with the liver — because the liver governs free coursing. If a person’s qi mechanism is blocked, what should you always think? The liver cannot course freely. So soothing the liver and moving qi is crucial — and mu xiang has exactly that action. Because it is warm, it works especially well for qi stagnation caused by cold-dampness and cold qi; it has a warming-and-unblocking action, which is what “warming the middle to harmonize the stomach” means.

Mu xiang also has a specialty — stopping diarrhea.

💬 Note from Doctor Luo: When is mu xiang especially useful? When the spleen and stomach are attacked by cold and qi becomes stagnant — chest and abdominal distension and pain, vomiting, or diarrhea. Especially diarrhea: when it is severe, mu xiang can warm the middle and stop the diarrhea — it regulates the qi and stops pain at the same time, and it also stops diarrhea. That is why you so often see mu xiang in formulas for diarrhea — this is the reason.

Interlude: “mu xiang is nephrotoxic”? — that’s qing mu xiang! Don’t confuse them

Speaking of mu xiang, Doctor Luo stops to bust a myth.

💬 Note from Doctor Luo: There is a controversy right now. You often see popular-science articles claiming mu xiang is nephrotoxic, “mu xiang is poisonous.” That is a misunderstanding. Why? The toxic one is called qing mu xiang (Aristolochia root). That herb does have kidney toxicity. But we basically don’t use qing mu xiang anymore. What we use — and what reputable pharmaceutical companies use — is mu xiang proper, and mu xiang has no kidney toxicity. The reason some articles claim “mu xiang is toxic” is simply that people confuse the names. There are unscrupulous herb dealers who substitute qing mu xiang for mu xiang in prescriptions — that is absolutely not allowed. The ancients distinguished them very clearly. So no: mu xiang is not nephrotoxic. The mu xiang used by reputable manufacturers is definitely not qing mu xiang, and it has no kidney toxicity.

Next time you see an article saying “mu xiang is poisonous,” first check whether it is talking about mu xiang or qing mu xiang.

Herb No. 2: Xiang Fu — the master of soothing the liver and resolving depression

Mu xiang warms the middle, orders the qi, and stops pain. Its partner is xiang fu (cyperus tuber).

💬 Note from Doctor Luo: Xiang fu is also a qi-regulating, pain-stopping herb — pungent, slightly bitter, sweet, neutral, entering the liver and triple burner channels. It regulates qi, resolves depression, stops pain, and regulates menstruation — and it is especially good at soothing liver qi. When liver qi is bound up, xiang fu soothes it beautifully. So in my prescriptions, whenever a patient has emotional issues, I generally add xiang fu, yu jin (turmeric), and the like. Xiang fu is particularly skilled at treating the qi stagnation of liver-spleen disharmony — the kind of spleen-stomach qi stagnation caused by unsoothed liver qi. For that, xiang fu works extremely well.

Why, when the spleen and stomach are blocked, should you think of the liver?

💬 Note from Doctor Luo: Everyone should carry this awareness — why is your spleen-stomach qi stagnant? On one hand you caught cold; on the other your dampness is heavy. But there is always a third factor: your liver’s free-coursing function has declined and can no longer dredge and discharge, so the qi stagnates. At that point you must soothe the liver qi open — that is why herbs like xiang fu are used. You’ll notice a common feature: both mu xiang and xiang fu are somewhat warm. What does the warmth do? It raises the liver qi — because when liver qi is uncomfortable here, it is usually not liver yin deficiency but liver yang insufficiency, the liver qi unable to sprout and rise, which also causes stagnation. We call this liver wood depression-stagnation (gan mu yu zhi). So you use something warm to revive the liver’s rising, sprouting qi.

Xiang fu is also a regular in gynecological formulas — for the same reason.

💬 Note from Doctor Luo: The liver governs free coursing, and women’s reproductive functions are closely tied to the liver’s coursing and discharging. That is why the conditions xiang fu treats include irregular menstruation, metrorrhagia and leukorrhea (abnormal uterine bleeding and vaginal discharge), and menstrual abdominal pain — disorders of the uterus (the liver also governs the blood vessels) caused by liver-qi stagnation that leaves the blood unable to move smoothly. Xiang fu can help regulate all of them. So women will notice that xiang fu appears in many gynecological medicines.

Mu xiang and xiang fu — two herbs that soothe the liver and regulate qi, serving as the formula’s monarchs for regulating qi and stopping pain. Next come the “heavy hitters.”

Hou Po + Qing Pi: transforming phlegm-dampness and breaking qi masses

Hou po (magnolia bark) — bitter, pungent, warm, entering the spleen, stomach, and large intestine channels.

💬 Note from Doctor Luo: Hou po warms the middle, descends qi, dries dampness, and transforms phlegm — these are its main actions. It warms the middle on one side, smooths the qi, and dissolves phlegm-dampness, especially pushing it downward and out. It treats the distension and oppression of the stomach and belly caused by phlegm-dampness obstructing the middle. When you see that a person, through cold-dampness or similar, has phlegm-dampness accumulating inside, plus food stagnation — food that was never digested, piling up in the abdomen — hou po is the herb that dissolves it and moves it downward. This is a fairly strong herb; its force is quite fierce. That is why I use it sparingly — usually around 3 grams, 6 grams at most, and I find that already achieves the effect. Its phlegm-transforming and accumulation-dissolving action is excellent.

Qing pi — the peel of the tangerine while it is still green, the partner of chen pi (aged tangerine peel), yet with a completely different temperament.

💬 Note from Doctor Luo: What is chen pi? The peel of the tangerine after it has turned red-yellow. Qing pi is the green one. Qing pi is a qi-breaking (po qi) herb. Its action is similar to chen pi’s, but it is much better at breaking qi. When qi gathers together and, mixed with phlegm-dampness inside the body, forms a mass — when it can no longer circulate at all and has formed a lump — qing pi is what dissolves the lump. That is qing pi’s role. Chen pi, by contrast, is for when the phlegm-dampness has not yet formed a mass: it regulates qi and transforms phlegm gently. Qing pi is called “breaking qi,” and its force is clearly greater. Qing pi enters the liver and gallbladder channels; its key actions are soothing the liver, breaking qi, scattering masses, and resolving phlegm.

What does qing pi treat? Doctor Luo gives two examples.

💬 Note from Doctor Luo: Hernia, for instance — hernias often arise when liver yang is insufficient and the coursing function declines, producing a hernia along the pathway of the liver channel. The treatment should use warm herbs with qi-breaking, qi-regulating power — qing pi works. Also, the various nodules and masses women get in the breast — those are related to the liver channel too, and qing pi is used for them. So qing pi soothes the liver and regulates qi, and it is especially effective for the masses and depressions caused by unsoothed liver qi. If you know Chinese medicine, you will see how extraordinarily careful the ancients were in thinking about the natural world — they worked out the different actions of a plant’s stems, leaves, and the peel of its fruit at different stages. Using the ten thousand things of this world to regulate the human body — that is a very great wisdom.

Zhi Ke + Bing Lang: opening up the “dead end”

Zhi ke is from the same family as the tangerine — north of the river they call it zhi (bitter orange), south of the river ju (tangerine). It is the fruit of the sour orange before it ripens, and its force is considerable.

💬 Note from Doctor Luo: Zhi ke also breaks qi and transforms phlegm; it dissolves accumulations and descends qi. It can dissolve phlegm-dampness and push it downward and out. So for chest and hypochondriac distension and oppression, food stagnation, or phlegm-dampness obstructing the middle causing qi stagnation, zhi ke is used to break the qi, dissolve the mess, and unload it.

Bing lang (betel nut) — this herb has quite a story: it is the “snack” of Hunan and Hainan people.

💬 Note from Doctor Luo: I lived in Hainan, and I really did see young men everywhere chewing betel nut. True, betel nut is not good for the mouth — it is somewhat carcinogenic, and long-term use is not acceptable — but we can use it occasionally: occasionally in a formula, in a very small dose. Why do so many people in Hunan chew betel nut, and so many in Hainan? Think about it: in damp-heavy regions, cold-dampness obstruction is common. Hainan is hot — how can there be cold-dampness obstruction there? Because when it is hot, people crave cold things and easily overindulge in them, which creates cold-dampness in the body. Add food stagnation: cold-dampness blocks the qi mechanism, things accumulate inside, and you get abdominal distension with un-resolved cold-dampness. That is when bing lang is used — bing lang breaks accumulations, descends qi, resolves water, and disperses phlegm. Whatever is piled up inside, it can dissolve and push out.

Bing lang also has a hidden skill: killing parasites.

💬 Note from Doctor Luo: Bing lang also kills parasites — in the south there can be parasitic infections and so on. So bing lang is a botanical medicine that ordinary people discovered can break up the pattern of cold-dampness accumulation in the body. Of course, we do not recommend chewing betel nut casually — chew it for many years and it may eventually cause oral cancer. But using a little betel nut in a prescription occasionally is fine. This is true of all medicines: many have some toxicity, but we must weigh the degree of toxicity against the urgency of the illness. Like the old man I mentioned — when life itself is at stake, a formula that contains a little bing lang is perfectly fine: it helps break open the qi mechanism, and it is not going to cause a new disease. We are always balancing the severity of the illness against the potency of the drug. If you insisted on using it continuously for ten years or more, of course we would not approve. Both Chinese and Western medicine hold this measure — Western drugs have side effects too; the question is how urgent the disease is. When the disease is urgent, use what is needed to save the life.

Chen Pi + Sha Ren: the gentle “qi-regulating pair”

After the qi-breaking heavy hitters comes a gentler pair — chen pi paired with sha ren (amomum fruit).

💬 Note from Doctor Luo: Chen pi, as everyone knows, is the partner of qing pi. Chen pi regulates qi and transforms phlegm, and removes dampness. Chen pi paired with sha ren — both regulate qi, resolve dampness, and harmonize the middle; both harmonize and regulate the spleen and stomach. These two are gentle: they do not break qi; they regulate qi and harmonize the middle. Especially sha ren — sha ren has the action of moving qi and regulating the middle (“xing qi tiao zhong”). What does “xing pi” mean? Li Shizhen said in the Ben Cao Gang Mu (Compendium of Materia Medica): “tonify the lung, move the spleen, nourish the stomach, benefit the kidney.” What does moving the spleen mean? It means rousing the spleen and stomach qi, awakening the recovery of their function. When qi stagnation and cold-dampness obstruct the middle, the spleen and stomach sink into a suppressed, function-inhibited state; sha ren can rouse the spleen and stomach qi and connect the qi mechanism upward and downward. So sha ren is a truly excellent qi-regulating herb.

Speaking of sha ren, Doctor Luo recalls the clever trick of a folk healer.

💬 Note from Doctor Luo: I once told the story of a folk healer I met. This old gentleman would tell patients: “Your spleen and stomach function is too weak — you may not even absorb the herbs I prescribe.” When the stomach itself is not working, and the medicine cannot be absorbed, what do you do? He would put sha ren into the formula, then tell the patient: “Take a handful of sha ren, break it open — take one fruit, crack the shell, and chew the little seeds inside like a snack. That opens up the spleen and stomach qi. Then drink the herbal decoction — only then will it work.” Look at this gentleman’s insight — his treatments were extremely effective, his clinic was packed, and everyone marveled: “How is it that a few doses cure me?” They said he paid great attention to spleen and stomach function. That is the experience of Chinese medicine.

Cang Zhu + Gan Cao: drying dampness, fortifying the spleen, harmonizing the herbs

The formula also contains cang zhu (atractylodes) and gan cao (licorice).

💬 Note from Doctor Luo: Cang zhu resolves dampness — pungent and warm, drying dampness, transforming phlegm, and fortifying the spleen; it pushes the dampness out of the body. Why? Because in this kind of spleen-stomach qi stagnation, it is too simple to think only of qi stagnation. Stagnation always involves cold-dampness obstructing the middle: once the qi stagnates and cannot circulate, phlegm-dampness stays behind even more easily. So you use cang zhu to dry dampness, transform phlegm, and fortify the spleen, expelling the dampness outward. Once the dampness is drained, then regulating and breaking the qi becomes much easier — the qi can actually be dissolved open. And gan cao? It harmonizes all the other herbs.

Overall assessment: an army of qi-regulating and qi-breaking herbs, reinforced with liver-soothing and phlegm-dampness-resolving power

Having examined all ten herbs, the formula’s structure is clear.

💬 Note from Doctor Luo: What characterizes this formula? It uses a large quantity of qi-regulating and qi-breaking herbs. Remember the concept of breaking qi: when qi stagnation is pronounced and the spleen and stomach function is already suppressed, blocked inside like a dead-end street — like a frozen computer. There is the situation. What do you do? You must open it up. And how? With qi-regulating and qi-breaking herbs. So the power in this formula is considerable. Then add liver-soothing herbs — you can see the intent: some of these herbs also address the liver channel, because the liver governs free coursing. At the same time add dampness-resolving, phlegm-transforming herbs — hou po, cang zhu, sha ren and the like all eliminate phlegm-dampness. Only when the phlegm-dampness is dissolved can the qi truly depart. So this formula, I think, is used quite classically — this famous formula is classic.

When to use it? — qi stagnation from cold-dampness and cold-yin causes; damp-heat won’t do

However good a formula is, it must be used in the right situation.

💬 Note from Doctor Luo: When is this formula used? Remember: basically when the qi mechanism is blocked by cold-dampness, cold, or yin-cold causes. If there is damp-heat — if the pattern is heat — Mu Xiang Shun Qi Wan is not really suitable, because all its herbs are warm and dry. At most you might use it briefly to break the deadlock, and then what do you add? Heat-clearing, damp-heat-resolving herbs. Usually the situation here is caused by yin-cold, and the qi stagnation is more pronounced: the spleen and stomach function is suppressed, the belly is distended and painful, the stomach and abdomen swell and ache, and the upper and lower cannot communicate — the qi mechanism is not flowing, the stomach qi cannot descend and instead goes upward, and below there is no stool, or the stool passes with difficulty — mostly the middle is severely distended. In that situation, Mu Xiang Shun Qi Wan can break the deadlock.

Crucial reminder: after breaking the deadlock, you must tonify and regulate the spleen and stomach

Finally, the point Doctor Luo keeps stressing — this medicine must not be taken long-term.

💬 Note from Doctor Luo: Remember: this formula is not for long-term use. Saying “Mu Xiang Shun Qi Wan is great, I’ll take it for six months” — no. It is not something you take for half a year; it is there to break the deadlock. And after breaking the deadlock, what next? You must tonify and regulate the spleen and stomach — use something like Xiang Sha Liu Jun Zi Wan (Aucklandia and Amomum Six Gentlemen Pill), Gui Pi Wan (Spleen-Restoring Pill), or Bu Zhong Yi Qi Wan (Tonify the Middle and Augment Qi Pill), and gently regulate the spleen and stomach with food therapy — shan yao (Chinese yam), lian zi (lotus seed), qian shi (fox nut), and so on. Tonifying the spleen and stomach, supporting the upright qi, is what follows Mu Xiang Shun Qi Wan: once I have helped you build up the upright qi, the qi mechanism will not be blocked again by other factors, and this state of qi stagnation will not return.

Open up the blocked qi mechanism, then nourish the weakened spleen and stomach — that is the complete way to use Mu Xiang Shun Qi Wan.
