Opening: in the dog days of summer, he insisted on scalding-hot food

Today we continue with more cases from Doctor Xue Lizhai (Xue Ji), the Ming dynasty director of the Imperial Academy of Medicine. The first patient was a ru zhe — a Confucian scholar, a man of letters. He had one habit that Doctor Xue Lizhai remembered at a single glance: si shi ji re yin shi — all four seasons, winter or summer, he would only eat food that was piping hot, almost scalding.

💬 Note from Doctor Luo: In winter, cold weather, hot food makes sense. But in high summer, in the dog days, when everyone else is eating cold noodles and mung bean soup, this man still had to have his food scalding hot — now that is interesting. This small detail is the most important clue in the whole case that follows.

Who was this patient, and what else was wrong?

Besides craving hot food, the scholar carried a whole string of complaints: tun suan — acid regurgitation; he would bring sour water up and then have to swallow it back down, which is why the Chinese character means “swallow”; ai qi — belching, and the belches carried the smell of rotting food; da bian bu shi — loose, unformed stools; and the most eye-catching of all: jiao zhi feng shi yang — the webs between his toes were itchy, damp, and oozing, looking very much like today’s athlete’s foot.

💬 Note from Doctor Luo: Look at this list — acid reflux, belching, loose stools, itchy oozing toes. A lot of people would immediately think: this must be damp-heat (shi re)! Athlete’s foot, heavy dampness, fire in the body. But Doctor Xue Lizhai did not think that way at all.

The stroke that decided everything: one “loves hot food” settles cold versus heat

How did Doctor Xue Lizhai judge it? He diagnosed spleen-stomach deficiency cold (pi wei xu han). On what grounds? On nothing more than that “craves hot food all year round.”

💬 Note from Doctor Luo: Why does he love hot food? Because his body is cold — his yang qi is insufficient. In summer the weather warms up and he feels a little more comfortable, but inside, his body is still cold. A person with fire inside longs for ice in summer; a person with cold inside feels awful at the least bit of cold food. So this one detail — “loves hot food” — told Doctor Xue Lizhai directly: this is a cold pattern.

Where is the cold? In the spleen qi. The spleen is weak, so it cannot transport and transform. Food should move downward, but instead it stops in the stomach and gets stuck there — so it pushes back up and becomes acid regurgitation and belching. A weak spleen cannot hold things in place, so the stools stay loose. With spleen qi deficiency cold and insufficient yang, diarrhea and unformed stools follow naturally.

The spleen is the “water controller”: why did the dampness run to the feet?

The most elegant diagnosis lay in the toe webs. When the spleen is weak, it not only loses the power to transport — it also loses control of the body’s fluids. The spleen governs the movement and metabolism of water in the body; when the spleen fails, water runs everywhere — this is what Chinese medicine calls dampness flooding (shi qi fan lan).

💬 Note from Doctor Luo: Where does the dampness go? If it runs upward, the eyes swell — the eyelids puff up as if a cicada were perched on them. If it runs downward, it reaches the feet — hence the itchy, oozing toe webs. Everyone, remember this: the moment you see itching and dampness and call it damp-heat, you may well be wrong. Here it is not damp-heat pouring downward; it is yang insufficiency plus spleen deficiency — too weak to control water, so cold-dampness floods the body. If you looked at the tongue, it would certainly be pale, swollen, and covered with saliva — the classic signature of yang deficiency with heavy dampness.

Breaking down the prescription: Six Gentlemen Decoction plus ginger and cinnamon, to strengthen the spleen and warm the yang

How was it treated? Doctor Xue Lizhai used Liu Jun Zi Tang (Six Gentlemen Decoction) plus ginger and cinnamon.

💬 Note from Doctor Luo: We have met the Six Gentlemen Decoction before: the Si Jun Zi Tang (Four Gentlemen Decoction) — ren shen (ginseng), bai zhu (atractylodes), fu ling (poria), gan cao (licorice) — is the foundation for tonifying spleen qi. Add ban xia (pinellia) to dry dampness and transform phlegm, and chen pi (aged tangerine peel) to move qi and eliminate dampness, and you have the Six Gentlemen Decoction — strengthening the spleen, moving qi, and draining dampness. On top of that he added ginger and cinnamon — sheng jiang (fresh ginger), though gan jiang (dried ginger) suits this better, and pao jiang (blast-fried ginger) works too — plus rou gui (cinnamon bark). What are those for? Warming the yang. One arm of the treatment strengthens the spleen, moves qi and drains dampness; the other warms the yang back up.

The setback: cured — but it came back whenever he tired himself out

The medicine worked, and the symptoms cleared. But there was a problem: any small lapse in care brought the disease back. If he let his habits slide, got tired, or ate something cold, it returned at once — zhu zheng reng zuo, all the complaints reappeared. What to do about that?

💬 Note from Doctor Luo: So many chronic diseases behave this way: take the medicine, feel better; stop, and it comes back. What does that tell you? The “engine” underneath is still short of power — the yang has not really been built back up yet.

Here is where Doctor Xue Lizhai’s skill shows: he added fu zi (aconite) to the same prescription — the formula unchanged, only one herb added, aconite, to push the warming action up a full notch.

💬 Note from Doctor Luo: Aconite is the heavyweight among warming herbs — its force is powerful. Ginger and cinnamon had warmed the yang, but not quite enough; add aconite, and the fire is complete. The result? Shu ji bu zai fa — after a few more doses, the disease never flared again. This is what happens when a quantitative change tips into a qualitative one: one herb added, and the whole picture transforms.

The second case: same itchy toe webs, but this time things were “sinking”

Right after that, Doctor Xue Lizhai saw a second patient: a man with a weary, listless body — one look, and the doctor’s visual diagnosis told him this man was constantly sluggish and lacking energy. His appetite was fine, but his toe webs were also itchy and damp, exactly like the first patient. And he had one distinctive extra symptom: xing zuo jiu ze zhong zhui — when he walked or sat for a long time, he felt a heavy, sinking sensation inside, as if his internal organs were being pulled downward.

💬 Note from Doctor Luo: Watch this! The symptoms look familiar, don’t they? Itchy toe webs again. But this man’s root problem is different from the first patient’s — the first was yang deficiency, craving hot food. This one is weariness and sinking — that is spleen qi deficiency with middle qi sinking (zhong qi xia xian).

Prescription comparison: Bu Zhong Yi Qi Tang plus fu ling and ban xia

What do you do for middle qi sinking? Doctor Xue Lizhai prescribed Bu Zhong Yi Qi Tang (Tonifying the Middle and Augmenting Qi Decoction) plus fu ling and ban xia — and the patient was cured.

💬 Note from Doctor Luo: Bu Zhong Yi Qi Tang works chiefly by tonifying the spleen, and it contains herbs like chai hu (bupleurum) and sheng ma (cimicifuga) that lift upward — they raise the sunken middle qi back up and supplement it. Fu ling is added to drain dampness; ban xia to dry dampness, move qi and regulate qi. Once the qi is lifted, the sinking feeling disappears — and the source of the dampness in the toe webs is cut off at the root.

The finishing touch: the same damp, itchy toes — treated in opposite directions

Setting the two cases side by side is where Doctor Xue Lizhai’s real mastery shows: the very same itchy, oozing toe webs, treated with completely different strategies.

💬 Note from Doctor Luo: The first patient craved hot food and was yang deficient — so the Six Gentlemen Decoction plus ginger, cinnamon and aconite, treating chiefly by warming the yang. The second was weary, with a sinking sensation and middle qi sinking — so Bu Zhong Yi Qi Tang plus fu ling and ban xia, treating chiefly by lifting. Why? Because the accompanying patterns differ: in one, the cold sits in the yang; in the other, the qi has collapsed downward. Once the disease mechanism (bing ji) is identified precisely, the very same symptom can be treated in almost opposite ways. This is the fine art of “same disease, different treatments” (tong bing yi zhi) — the heart of Chinese medicine.

Bonus one: Si Shen Wan for the “straight-pipe rectum” diarrhea

At this point in the lecture, Doctor Luo shared a personal story from a few days earlier. A friend came to him complaining of diarrhea that had dragged on for a long time — not severe, but the moment he ate anything the least bit off, he would immediately have to run. He described himself as having “a rectum like a straight pipe.”

💬 Note from Doctor Luo: The moment I heard that, I knew it was yang insufficiency! I recommended a prepared Chinese medicine — Si Shen Wan (Four Miraculous Herbs Pill), which Tong Ren Tang sells under the name Rou Kou Si Shen Wan. It is a traditional formula. My friend took it, and — my goodness, the effect was obvious — his stools formed up right away and the diarrhea stopped. This kind of loose stool caused by insufficient yang is extremely common, and warming the yang is the only way it will truly get better.

Bonus two: why does athlete’s foot keep coming back? Look at your internal environment first

Finally, Doctor Luo brought the conversation back to “athlete’s foot.” Today, itchy, oozing toe webs are often linked to fungal infection, and there are plenty of antifungal sprays and washes on the market — all of them usable.

💬 Note from Doctor Luo: But have you ever asked yourself — why can the fungus survive on your foot in particular? It is because your internal environment has changed. Doctor Xue Lizhai’s thinking here matters enormously: improve the environment inside the body. When the spleen is no longer weak and dampness stops flooding, the root cause is severed, and the problem on the foot resolves on its own. Some people say things like “the body is expelling dampness, don’t treat it — if you treat it, it will get blocked up.” I don’t really agree with that. Look at Doctor Xue Lizhai’s case records: he hurried to regulate the inside of the body so the dampness could be controlled, and then the problems naturally stopped. Local treatment is fine, but correcting the root is better. Of course, if the athlete’s foot is truly damp-heat pouring downward (shi re xia zhu), then you must clear damp-heat — use huang lian (coptis) and huang bai (phellodendron) to clear damp-heat, and tu fu ling (glabrous greenbrier) to eliminate dampness. That is a different path altogether.

What to take away

• “Loves hot food” is a diagnostic clue. A patient who craves scalding-hot food all year round is cold inside — treat by warming, not by clearing.
• A weak spleen loses control of water. When spleen qi fails, dampness floods: upward to the eyes, downward to the feet — where it shows up as itchy, oozing toe webs that look like athlete’s foot.
• Itching + dampness does not automatically mean damp-heat. Pale, swollen, saliva-covered tongue points to yang deficiency with cold-dampness — the treatment is warming the yang and strengthening the spleen.
• Same symptom, opposite treatments: yang deficiency → Six Gentlemen Decoction plus ginger, cinnamon, and finally aconite; middle qi sinking → Bu Zhong Yi Qi Tang plus fu ling and ban xia, lifting the qi with chai hu and sheng ma.
• When a chronic illness keeps relapsing, one more herb can be the tipping point — Doctor Xue Lizhai added a single herb, fu zi (aconite), and the disease never returned.
• Athlete’s foot that recurs is a message about your internal environment — strengthen the spleen and control the dampness, and the skin problem clears from the root.
