Opening: this bowl of yam water saved a woman on the verge of death
For the past several episodes, Doctor Luo Dalun has been showing us the wonders of Doctor Zhang Xichun’s use of Chinese yam (shanyao). Today’s case is a genuine, life-or-death emergency — the patient was already lying in bed, and the other physicians had all said she “could not be saved.” When Doctor Zhang Xichun stepped in, the medicine he leaned on was, once again, the humble Chinese yam.
💬 Note from Doctor Luo: Today I want to make one point very clear: Chinese yam is not just for cooking porridge for children. In Doctor Zhang Xichun’s hands, it is a medicine capable of turning the tide at the moment of greatest danger. Let us watch how he used it.
Who was the patient? A neighbor’s daughter-in-law, five months pregnant
This patient came from Doctor Zhang Xichun’s own village — a place called Tongzhuang near his hometown of Yanshan. She had married into the Guo family of a neighboring village. At the time she fell ill she was five months pregnant, and the baby was due before long.
💬 Note from Doctor Luo: She was a fellow villager — Doctor Zhang Xichun could call her name. So this case record is absolutely reliable; many of the cases in his book are about people close to him.
How did the illness begin? Typhoid fever at five months of pregnancy, and the baby slipped away
When she reached five months of pregnancy, she suddenly came down with a cold-induced febrile illness (shang han) — an external invasion, and a severe one at that. Just three or four days in, the fetus suddenly slipped out — she miscarried.
💬 Note from Doctor Luo: Why did she miscarry? The fetus was never firmly anchored to begin with; then a severe external invasion threw the whole body into disorder — and the pregnancy could not hold.
After the miscarriage: burning thirst, wheezing, phlegm surging up — and the doctors called in made it worse
What symptoms appeared after the miscarriage? Feverish thirst and dryness in the upper body — parched and dry, her mouth so dry she could not stop wanting water; continuous wheezing — she gasped and panted without pause; abundant phlegm surging upward — phlegm kept rising and she was forever spitting.
The state of things plainly was not good. The family hurriedly called in doctors to write prescriptions — but far from improving, the illness turned into slippery diarrhea (hua xie).
💬 Note from Doctor Luo: Pay attention — here is a crucially important point that Doctor Luo spelled out in detail today: slippery diarrhea (hua xie) and dysentery (li ji) are two entirely different conditions, and they are treated with completely different medicines. Never mix them up.
Slippery diarrhea vs. dysentery: both are diarrhea, but the treatments are worlds apart
What is dysentery? The belly hurts terribly — the pain is unbearable, you rush to the toilet, and even after you have emptied yourself, the belly still hurts — this is what we call tenesmus (li ji hou zhong). It is an externally contracted illness with a heavy load of external pathogen inside. At such a time you must clear the pathogen and push it outward, helping the body drive the evil qi out.
What is slippery diarrhea? Some people have diarrhea every day, but it is not the fierce, cramping pain of dysentery — there is a little discomfort, you go to the toilet, empty yourself, and feel fine for a while, then a little uncomfortable again. For example, in autumn, the moment you catch a chill, your stools turn loose and unformed — that is slippery diarrhea.
💬 Note from Doctor Luo: So remember: slippery diarrhea does not come with that violent abdominal pain, and Chinese yam treats slippery diarrhea — the kind rooted in insufficiency of upright qi. For dysentery, yam is generally not used; you need to resolve toxins and push the pathogen out — unless the upright qi is truly depleted, and only then might yam be considered. That is the difference! Some friends have left comments saying, “whenever my child has a tummy upset I give him yam” — that is not right. You must first distinguish whether it is slippery diarrhea or dysentery.
How grave was it? Ten-plus bowel movements day and night — the doctors flatly refused to treat her
The woman turned into slippery diarrhea, more than ten times in a day and night (zhou ye shi yu ci). Her belly felt slightly uncomfortable, she went to the toilet, emptied herself, felt a little better, and then a little while later felt bad again.
When the doctors saw this state — the illness not improving but instead draining downward — they flatly refused to treat her, saying: this patient is in imminent danger of death; she may not pull through; she cannot be saved.
The family was terrified.
💬 Note from Doctor Luo: The illness had become this dangerous — the other doctors had given up. Fortunately, her maternal family knew Doctor Zhang Xichun and knew how skilled he was, so they hurriedly invited him.
Doctor Zhang Xichun arrives: a surging-slippery pulse that turns empty on deep pressure — the upright qi is badly depleted
Doctor Zhang Xichun placed his fingers on the pulse: it was surging and slippery (hong hua) — it beat with vigor, somewhat slippery; but on heavy pressure it was suddenly hollow (zhong an ze huo ran) — press down, and the inside was empty! What does this mean? The upright qi is extremely insufficient. And the two chi (kidney) positions were the worst of all (liang chi mai you shen) — the chi pulse governs the kidneys, and the kidney qi was nearly exhausted.
💬 Note from Doctor Luo: On the surface the pulse seems strong, but pressed deeply it is hollow — this is the classic pulse of “strong outside, withered within” (wai qiang zhong gan). There is external pathogen on one side and badly depleted upright qi on the other. At such a time attacking the pathogen alone will not do, and tonifying alone will not do either. Doctor Zhang Xichun had his own emergency method.
First formula: raw Chinese yam 2 liang (about 60 g) plus one sour pomegranate — urgent astringing of the diarrhea
Doctor Zhang Xichun wanted to deal with the emergency first. His first move: sheng shanyao (raw Chinese yam) — meaning dried yam slices — 2 liang (about 60 g), plus one sour pomegranate.
What was the sour pomegranate for? Astringing and securing (gu se shou lian). And note carefully: Doctor Zhang Xichun used the sour pomegranate whole — rind and flesh pounded together — and decocted it that way, including the pomegranate rind.
💬 Note from Doctor Luo: The sour pomegranate is a very special anti-diarrhea medicine: it not only stops the diarrhea, it can also kill off the external pathogen inside. An ordinary astringent herb, once it secures things, simply locks the pathogen inside; a purely antibacterial herb, by contrast, cannot hold the upright qi in place. The pomegranate does both — it both astringes and secures, and it resolves toxins and clears the pathogen. That is why Doctor Zhang Xichun, when slippery diarrhea was severe, reached for raw Chinese yam paired with sour pomegranate.
Doctor Zhang Xichun pounded the sour pomegranate, rind and all, decocted it together with the yam into one large bowl of liquid, and had the woman take it in three divided doses. The result — the slippery diarrhea began to improve!
💬 Note from Doctor Luo: These days it may be hard to find sour pomegranates — the ones in the shops are all sweet. No matter — pomegranate rind (shiliu pi) has the same action. Paired with yam, it can stop the diarrhea and clear pathogenic qi from the intestines and stomach. This is another of Doctor Zhang Xichun’s combinations — write it down.
The external pathogen was still there: tidal fever at three in the afternoon — tonify the deficiency and clear the pathogen together
The slippery diarrhea was stopped, but the external invasion remained — the wheezing and phlegm were still there. Doctor Zhang Xichun felt the pulse again: the surging-slippery force was still quite solid (hong hua zhi li jiao shi) — still very strong. He reasoned: although she is deficient, the external pathogen is still present, so at this point he must tonify the deficiency and clear the external pathogen at the same time.
It happened to be about three o’clock in the afternoon, and the patient said: every afternoon I get tidal fever (chao re) — the body heats up at a fixed time, like the tide; moreover her spirits were extremely tired, and she slept poorly at night.
💬 Note from Doctor Luo: Tidal fever, weariness, and a still-forceful pulse — this is external pathogen and upright deficiency existing side by side. Doctor Zhang Xichun judged that both aspects had to be cared for, so he gave a very famous formula.
Second formula: Shanyao Huashi Tang (Chinese Yam and Talc Decoction), sipped slowly while warm
What formula? Sheng shanyao (raw Chinese yam) 1.5 liang (about 45 g) — not a large amount; huashi (talc) 1 liang (about 30 g) — talc is for clearing damp-heat and draining it outward; sheng hangshao (raw white peony) 4 qian (about 12 g) — to soften the liver and restrain yin; plus gancao (licorice root) 3 qian (about 9 g). Decocted into one large bowl of soup.
Doctor Zhang Xichun had written specially about the yam-and-talc pairing (shanyao pei huashi) — one side tonifies the upright qi, the other clears damp-heat.
💬 Note from Doctor Luo: How you drink this formula matters: sip it slowly while warm (xu xu wen yin) — take it little by little, one mouthful at a time. Why? Let the medicine act on the upper body and take effect gradually, instead of downing it all at once.
And the result? That very night, the woman slept peacefully — tonifying the upright qi on one side, restraining yin on the other, she gradually fell asleep. The thirst and the slippery diarrhea both recovered, and the wheezing eased by about half.
Third move: reduce the doses, add astringents — one dose completed the cure
Doctor Zhang Xichun wrote another prescription: the yam and the talc each reduced by 5 qian, plus sheng longgu (raw dragon bone) and sheng muli (raw oyster shell) 8 qian (about 24 g) each — these two are astringent and securing, holding the upright qi firmly in place.
The result: one dose of medicine and the illness was cured — one dose, complete recovery.
💬 Note from Doctor Luo: Look at this case: a woman who had miscarried, invaded by external pathogen, with insufficient upright qi and the external pathogen present at the same time. Doctor Zhang Xichun grasped the proportions just right — with good ratios, he essentially cured the illness with one and a half doses of medicine. What was the most crucial thing here? Using dried Chinese yam to support the upright qi — using it at the moment of crisis, when the illness is grave. That is the core lesson of this episode.
Bonus: Doctor Luo’s critical-care experience — yam water to revive the stomach qi
Doctor Luo says that today many patients are gravely weakened: hospitalized patients, people in the ICU, those who have lain in bed for a long time, the very old who are critically ill, people whose upright qi cannot hold up (zheng qi bu zhi) — at such a time, what can be poured into them?
Dried yam slices boiled in water — 100 grams of dried yam slices boiled in water. If any liquid at all can be given, give this water. Why? To support the upright qi.
💬 Note from Doctor Luo: The greatest quality of Chinese yam is that it activates the energy of the spleen and stomach and restores their function. In the old days, when a veteran physician took a pulse and said “this person’s stomach qi is already gone (wei qi yi jue),” the illness was usually desperate, and the patient might not be saved; if he said “the stomach qi is still present (wei qi shang zai),” then there was still a chance, still room to rescue. Feeling the pulse for whether the stomach qi is present is an extremely important key to judging the prognosis. How do you help the stomach qi revive? Chinese yam has this capacity — this is an experience I learned from Doctor Zhang Xichun’s book: when a severely ill person takes yam water little by little, the upright qi can gradually build up, the spleen-stomach qi revives, and once the patient can absorb a little nourishment, he has provisions — and can fight again.
Many people in hospital are kept alive by intravenous drips while their spleen-stomach function slowly withers. If at such a time you can help the stomach qi revive and stir it to growth, the patient may gain a chance at rescue and pull through.
💬 Note from Doctor Luo: That is why Doctor Zhang Xichun, in his case studies, so often placed Chinese yam into the treatment of severe, critical illnesses — many patients who seemed too breathless and too weak to survive were saved with dried yam. If you ever meet such a situation in life, I recommend yam: it is gentle, it is food, but its power to turn the tide is absolutely not to be underestimated. That is the lesson Doctor Zhang Xichun’s case gives us.
