The opening: have you ever seen an injury that doesn’t bleed?
Today we continue with the case stories of Doctor Xue Lizhai (薛立斋). This case has a particularly amusing origin — a scholar went for a pedicure, and the pedicure produced something very strange.
💬 Note from Doctor Luo: Pedicuring was already a trade in the Ming dynasty, exactly as it is today — a craft built on a small knife. But this time, one stroke of the knife raised a question: he was cut, yet no blood came out. What is going on? Let’s savor it slowly.
Who was the patient? A Ming-dynasty scholar, and a pedicure that went wrong
The patient was a scholar — a studious, learned man. One day he went for a pedicure, and the pedicurist, not paying close enough attention, cut into the flesh of his left big toe — not just the nail, but deep into the flesh.
An injury to the flesh should bleed and should hurt, right? Here’s the strange part: there was no blood, no pain — his body seemed entirely normal, as if nothing had happened at all.
💬 Note from Doctor Luo: He was cut, yet there was no bleeding and no pain, just like usual. Why? Keep reading — this is the most important signal in the whole case. There really are such people: their qi and blood are so insufficient that when they are injured, the blood simply “won’t come out.” They look as if nothing happened.
The strange thing comes later: after a nap, the foot is as good as new
Later, this scholar fell into irregular eating and overwork — erratic meals, tiring work — and his body was gradually consumed, his condition slipping day by day. That’s when his foot began to act up: it became heavy, slightly swollen and painful — the foot felt heavy, mildly puffy and sore.
But here’s the marvel: all he had to do was sleep — day nap or night sleep, when he woke, the foot was back to normal (“昼寝夜寐，足如故”).
💬 Note from Doctor Luo: Note this detail — he felt better after sleeping. Sleep nourishes qi and blood; if the foot returns to normal after rest, the problem is not an excess pathogen but a failure of qi and blood to reach the part — give it a rest and it recovers. This is an important clue pointing to deficiency. So he decided to get some treatment and asked a doctor for a prescription.
How did the earlier doctor treat him? Clearing heat and toxins — and bringing on chills, fever, swelling and pain
The doctor took one look: a swollen, painful foot? That must be heat toxin! So he prescribed a heat-clearing, toxin-resolving decoction (清热解毒之剂).
The result? Chills and fever, swelling and pain — his body alternated between cold and hot, and the swelling and pain only got worse.
💬 Note from Doctor Luo: Heat-clearing, toxin-resolving medicines are not forbidden — when heat toxin is really present, you genuinely need them. But in Doctor Xue Lizhai’s case records we see far too many people misusing them: the body is clearly deficient, yet the moment there’s swelling, pain or fever it gets treated as heat toxin, and the more it’s cleared, the worse it becomes. Why? Keep reading.
Doctor Xue’s thinking: one detail cracks the case — the spleen channel starts at the big toe
Doctor Xue Lizhai examined him and said it in a single sentence: the spleen qi has been injured.
What made him so sure? Besides all the earlier symptoms, there was one especially crucial clue — “the spleen channel starts at the big toe” (盖脾起于足大指).
The spleen channel’s course begins at the big toe. And this patient was injured precisely on his left big toe — right at the starting point of the spleen channel!
💬 Note from Doctor Luo: The injury itself may not have been serious, but it acted as the “trigger”: the patient’s spleen and stomach were already weak from irregular eating and overwork; then the starting point of the spleen channel was injured, and the injured channel in turn affected the spleen — multiple clues all pointing to one answer: the spleen qi is injured and qi and blood are greatly depleted. When Doctor Xue Lizhai diagnosed, the channel pathways were the ruler in his hand.
The truth revealed: not that the wound is shallow — the qi and blood are too deficient
Why does flesh get cut without bleeding? Doctor Xue Lizhai’s explanation is thorough: this man’s qi and blood were extremely insufficient.
A normal injury bleeds a little; but this man’s blood basically never came out — not because the wound was shallow, but because qi and blood were so deficient that even the blood “couldn’t come out.” The body was barely managing on a “low-level balance”: functions were running at a low ebb, but everything tolerated everything else, so he looked like a healthy person. Then irregular eating and overwork injured the spleen qi, the righteous qi weakened, this fragile balance broke — and only then did symptoms show. And when the cold, heat-clearing, toxin-resolving medicines arrived, the spleen qi was injured even more, so chills, fever, swelling and pain erupted together.
💬 Note from Doctor Luo: This is a very telling sign of deficiency — people who are extremely deficient sometimes don’t look deficient at all. They seem fine day to day, then collapse at the first gust of wind. Such patients are the last ones who should be attacked with cooling, purging methods as if they had excess — attack once, the righteous qi sinks further, and the illness worsens.
The prescription: Shiquan Dabu Tang — why not Buzhong Yiqi Tang?
Once the direction was set, Doctor Xue Lizhai prescribed: Shiquan Dabu Tang (Ten Complete Great Tonification Decoction). After drinking it, the illness was cured.
But you might ask: isn’t Doctor Xue Lizhai famous for Buzhong Yiqi Tang? If the spleen qi is deficient, why not use Buzhong Yiqi — why Shiquan Dabu instead?
💬 Note from Doctor Luo: Good question. The key is this: this patient’s spleen qi was injured too severely, and qi and blood were already greatly depleted — the spleen is the source that generates qi and blood, so spleen deficiency ends in qi-and-blood insufficiency. At this point the picture is dominated by righteous deficiency; the urgent task is not to lift the qi mechanism but to rebuild qi and blood quickly! That’s why he used Shiquan Dabu Tang. Once qi and blood are restored — and only if the qi is still tending to sink — then Buzhong Yiqi Tang can be used to lift it. No rush.
Breaking the formula apart: Bazhen Tang as the base, with huang qi and cinnamon as the finishing touches
What exactly is Shiquan Dabu Tang? It is built on Bazhen Tang (Eight Treasures Decoction) — the qi-tonifying Sijunzi Tang (Four Gentlemen Decoction) (ren shen, bai zhu, fu ling, gan cao) combined with the blood-nourishing Siwu Tang (Four Substances Decoction) (shu di huang, dang gui, bai shao, chuan xiong), tonifying both qi and blood — then huang qi (astragalus) is added to strengthen the qi, and rou gui (cinnamon) to warm things up slightly.
💬 Note from Doctor Luo: Why add cinnamon to warm things up? Because all those cold medicines the earlier doctor gave had injured the body, and it needed a little warmth. Notice the finesse of Doctor Xue’s prescribing — he doesn’t tonify mechanically; he has also factored in the damage done by “the previous doctor’s mistake.” Once qi and blood are replenished, for follow-up care, spleen-regulating formulas like Xiang Sha Liu Jun Zi Tang (Six Gentlemen Decoction with amomum and costus root) or Buzhong Yiqi Tang can all follow.
Extension one: injuries that don’t bleed, and pale limp sores — both are qi-and-blood deficiency
Though this case record is short, Doctor Luo uses it to explain a common surgical phenomenon: when people’s qi and blood are deficient, even their wounds can’t produce blood.
He says he has really seen it: someone has a sore on the body that bursts open with no blood inside; some sores are pale and limp — not red, not swollen, sitting there for a long time without developing. Why? Qi and blood are insufficient, too weak to push the pathogen out, so the body and the sore maintain a “low-level balance”: it can neither expel the pathogen nor get worse.
💬 Note from Doctor Luo: At such a moment, giving heat-clearing, toxin-resolving medicine only injures the spleen qi further — the more the righteous qi is damaged, the less able the body is to expel the pathogen, and the worse the illness gets. So the answer is to tonify — build up the righteous qi until the body can drive the pathogen out by itself. The ancients said huang qi can “support and expel toxins and pus” (托毒排脓) — for those sores that drag on forever without healing, it’s the tonifying qi that “supports” the sore out. I explained this principle in detail when I talked about huang qi.
Extension two: surgical history — Chen Shigong also loved Shiquan Dabu Tang
So you see, tonifying formulas like Shiquan Dabu Tang were routinely used in ancient surgery.
💬 Note from Doctor Luo: The great Ming-dynasty surgeon Chen Shigong — the author of Orthodox Surgery (《外科正宗》) — created his Bazhen Gao (Eight Treasures Paste) precisely for this kind of condition: righteous qi insufficient and sores that never heal. And when qi and blood were truly exhausted and the sore couldn’t even erupt, Chen Shigong also used Shiquan Dabu Tang. In the old days many people were malnourished: they had wounds, the pathogen couldn’t be expelled, so Shiquan Dabu Tang was used to build up the righteous qi and let the pathogen out — this is an especially important thread of thinking in surgery.
Extension three: when channels are blocked, the organs go wrong — the famous pig experiment
Doctor Xue’s phrase “the spleen channel starts at the big toe” rests on a major Chinese medicine theory: channels connect to the organs. The channels provide defense for the body surface and deliver nourishment to the organs; when a channel goes wrong, the organs go wrong.
Doctor Luo tells of an experiment done by the Acupuncture Institute of the China Academy of Chinese Medical Sciences: they located the spleen and stomach channels on pigs and blocked them with a pectin-based gel — and the pigs began refusing food, their bellies swelling bigger and bigger, until finally they died. The researchers were puzzled: they hadn’t eaten, so why were the bellies so distended? On dissection — whoosh, a blast of foul gas came out. The bellies were full of gas! With the channels blocked, the organs received no nourishment and every function went haywire.
💬 Note from Doctor Luo: This explains a great deal: why does Zusanli (ST36) — an acupoint on the leg — strengthen the spleen and stomach? Because needling and moxibustion open up the blocked channel, and the organ function recovers. I’ve seen it myself: someone sprained an ankle, injuring the area of the urinary bladder channel, and afterward he couldn’t urinate — once we activated blood circulation and repaired the channel passage, the urine flowed again. So if symptoms appear after a body injury, you can analyze: where is the injury, which channel does it relate to, which organ? This is the wisdom the ancients left us.
Closing: an injury without bleeding — first ask whether the body is “deficient”
Today’s little case record is short but thought-provoking: a cut that doesn’t bleed and doesn’t hurt is not a light injury — it means the qi and blood are too deficient; and the more heat-clearing, toxin-resolving medicine you take, the worse it gets, because a deficient person cannot withstand attack. Doctor Xue Lizhai used Shiquan Dabu Tang to rebuild qi and blood, and the illness was cured.
💬 Note from Doctor Luo: When qi and blood truly run out, the body no longer even has the ability to bleed — that is the ultimate signal of “deficiency.” The beauty of studying Chinese medicine is that you can use this framework to analyze where exactly the body has gone wrong and how to adjust it. Thank you all for listening — tomorrow we’ll continue with more of Doctor Xue Lizhai’s case stories.
