Before we start: younger listeners, please step out of the room
Before telling today’s story, Doctor Luo Dalun makes a declaration: if there are children nearby, don’t let them listen — because today’s case touches on adolescence and on “the stirring of desire,” something of an adults-only topic.
💬 Note from Doctor Luo: Why warn everyone first? Because the core lesson of this case is that “every time desire stirs, kidney essence is silently drained” — telling this to children who haven’t grown up yet would do more harm than good. Once they’re grown, it will be exactly the right time to hear it.
The main character is a patient recorded in the medical books of Doctor Xue Lizhai (Xue Ji), director of the Imperial Medical Academy in the Ming dynasty: a 14-year-old tong zi (an unmarried boy).
Who was the patient? A 14-year-old boy who suddenly ran a fever and vomited blood
What does “tong zi” mean? It means a boy who has never married. Doctor Luo explains that in ancient times a 14-year-old could already be married — once married, a boy could no longer be called a “tong zi.” This boy wasn’t married, so that’s what he was called.
His illness sounds frightening: fever and vomiting blood.
💬 Note from Doctor Luo: This fever wasn’t a high burning one — it was a sensation of deficiency heat deep inside the body. Vomiting blood was genuinely common in ancient times, and hospitals still see it constantly. When the boy fell ill, his family hurriedly called in doctors — several of them — none helped, and he only got worse. Finally they came to Doctor Xue Lizhai.
The more cold medicine, the worse it got — where was the problem?
Doctor Xue Lizhai examined him and said the treatment should be to supplement the middle (bu zhong yi qi) and nourish the source of transformation (zi hua yuan) — in other words, to build up the spleen and stomach. “Hua yuan” means the source that generates and transforms, and in this framework that is the spleen and stomach. His point: first, support the upright qi.
💬 Note from Doctor Luo: Hearing this, the family balked: “Vomiting blood — blood coming out surely means heat! We should clear heat with cooling medicines. Your Buzhong Yiqi Tang is warm and tonifying — how could that be right?” So they ignored Doctor Xue Lizhai and went back to cold, cooling, fire-draining herbs. And the result? The illness grew worse and worse.
Defeated, they returned to Doctor Xue Lizhai. This time everyone gathered around and pressed him with the question everyone had been quietly wondering…
Everyone’s doubt: a 14-year-old who’s never married — where would kidney deficiency come from?
In the treatment that followed, Doctor Xue Lizhai used Buzhong Yiqi Tang plus Liuwei Dihuang Wan, two formulas together — one to build the spleen, one to nourish the kidneys. The family and other doctors were puzzled:
“The boy is 14 and unmarried. How could he have kidney deficiency? And why are you using ginseng and astragalus to supplement qi?”
💬 Note from Doctor Luo: That’s a good question. Whether or not the kidneys are deficient has nothing to do with whether someone is married. Doctor Xue Lizhai answered by citing two ancient authorities — the first being the great Yuan dynasty physician Zhu Danxi.
Zhu Danxi said it long ago: when desire stirs, kidney essence is silently consumed
Doctor Xue Lizhai quoted Zhu Danxi:
“The kidney governs storage and closure; the liver governs free flow and discharge. Both organs carry ministerial fire (xiang huo), and their root attaches upward to the heart. When the heart is moved by something in the world it stirs easily; once it stirs, ministerial fire flares up in response. Even if no union takes place, essence is silently drained.”
💬 Note from Doctor Luo: What does this mean? The kidney is in charge of storing, the liver of discharging, and both organs hold “ministerial fire” — whose home base is the heart. When the heart is touched by something — say, the mind is moved by what it sees — the ministerial fire leaps up at once. Even though nothing actually happens, kidney essence is already quietly being consumed. Zhu Danxi’s point: draining kidney essence doesn’t require sexual intercourse. Whenever your heart stirs and desire rises, the fire moves and essence drains silently.
A medical book “dug out of a tomb”: The Posthumous Writings of the Chu Family (Chushi Yishu)
The second ancient authority Doctor Xue Lizhai cited was a book — The Posthumous Writings of the Chu Family (褚氏遗书).
💬 Note from Doctor Luo: This book has an extraordinary history. During the Southern Qi dynasty, a high minister named Chu Cheng — a physician of great skill who treated many rulers and officials — wrote several books. Later his tomb was robbed — traditionally said to have happened during the chaos of the Tang dynasty, around the Huang Chao rebellion — and people discovered that the stone walls of his burial chamber were carved with writing. It turned out to be his posthumous writings! They were copied down and published — that became the Chushi Yishu.
The book is short, but it lays out a complete system of qi, blood, essence, and fluids in the human body. The ancients felt it resonated with the Huangdi Neijing (Yellow Emperor’s Inner Canon), so it was frequently quoted. Its chapter “Jing Xue Pian” (On Essence and Blood) says:
“If a young man, before his essence has fully accumulated, engages with a woman and lets his essence flow, then his five bodies will carry deficiencies, and in days to come strange and hard-to-name illnesses will arise.”
💬 Note from Doctor Luo: In plain words: if a boy lets his essence flow before it has fully accumulated and matured, then the five organs (the original text says “five bodies”) will be left deficient somewhere. He may look young, strong, and healthy now — but some day, without warning, strange and indescribable illnesses will surface. When Doctor Xue Lizhai quoted this he wrote “five organs,” but Doctor Luo notes the original text actually says “five bodies” — the meaning is the same. Why does this hold? In Chinese medicine, each of the five organs stores its own essence, and kidney essence is the root: when kidney essence is full, the essence of all five organs is full; when the five organs have surplus essence, it is stored back into the kidneys. If your kidney essence is depleted, the essence of the five organs can never be substantial — the foundation of the body is hollow.
Doctor Luo’s modern reading: the body really does “prepare”
Are these two ancient passages right? Doctor Luo Dalun unpacks them in plain language.
💬 Note from Doctor Luo: Many people think “a moment of desire drains essence” sounds too mystical. Western medicine will tell you “semen is just protein — losing it is harmless.” But think about this: a space shuttle — chemically analyzed, it’s just iron. Yet can you price it the same as scrap iron at a toll station? Think of how many companies ran, how much human effort went into building it! The body is the same. When desire begins to stir, the body has already started preparing for what might come: hormones adjust, functions mobilize. Chinese medicine calls this “ministerial fire flaring up”; in modern terms, the body’s engine has already started turning over. It’s like a missile that’s already ignited and left the launch tube — even if it’s never fired, the expenditure of that journey has already happened.
Doctor Luo also offered examples from nature: animals don’t breed year-round; they have seasons. Look at the kapok tree in front of your door — every year it blooms, sets seed, and sends seeds drifting on the wind, working a whole year just to reproduce. The Pacific salmon grows weak the moment it finishes laying its eggs and hurries toward death — reproduction consumes enormous energy. Humans can reproduce year-round, but the cost is just as real.
💬 Note from Doctor Luo: What shocked me most was once, in a net café in my hometown, I saw a group of boys in fifth or sixth grade, or first or second year of middle school, huddled together watching porn — utterly absorbed. Their parents thought their kids had gone to school early in the morning and had no idea what they were really doing. Stirring the mind and heart every single day like that — how could a child’s spirit not wither? The essence is being silently drained while the body has no idea. When such boys grow up, in their twenties and thirties their bodies are terribly weak, and they go doctor-shopping everywhere: stomach problems, endless diarrhea, fear of cold, listlessness, pale complexion… Young men like this are extremely common now, and doctors think they have mental problems. The truth is, their essence was wounded far too early.
Breaking down the prescription: why do Buzhong Yiqi Tang + Liuwei Dihuang Wan stop the fever and the bleeding?
Back to the case. A 14-year-old with fever and vomiting blood — what is the actual disease mechanism?
💬 Note from Doctor Luo: The fever is qi deficiency. He had wounded his upright qi; his qi had sunk — this is the path of “sweet and warm herbs dispel great heat” (gan wen chu da re), so the qi had to be lifted back up. The vomiting blood is deficiency fire — kidney yin insufficient, yin deficiency generating internal heat, deficiency fire rushing upward and forcing the blood out. So Doctor Xue Lizhai used two formulas: Buzhong Yiqi Tang to tonify qi, the spleen, and the lungs — when the spleen and stomach are fully built, lung qi is full; when the metal of the lung is full, it can generate the water of the kidney — this is the path of “tonify the lung to generate kidney water.” Then he added Liuwei Dihuang Wan to directly nourish kidney yin. Once kidney yin is nourished, deficiency fire naturally settles, the blood stops coming up, and the fever subsides.
Using cold herbs like huang lian (coptis) to clear heat was wrong — there was no excess heat here at all. This was deficiency fire arising from kidney yin deficiency.
The result and the formula pattern: the boy recovered, and Doctor Xue Lizhai’s “golden combination” is worth remembering
What happened? The boy was cured.
💬 Note from Doctor Luo: Remember this combination: Buzhong Yiqi Tang + Liuwei Dihuang Wan — this is Doctor Xue Lizhai’s signature pattern for kidney essence deficiency and deficiency fire from kidney yin deficiency. Used alone, Liuwei Dihuang Wan doesn’t have this much power. First use Buzhong Yiqi Tang to generate kidney water by tonifying the lungs, then pair it with Liuwei Dihuang Wan to nourish kidney yin — the effect is better. Many people today with depleted kidney essence can refer to this approach.
In closing: a calm mind and few desires are the best tonic
The meaning of today’s case isn’t just in the formula.
💬 Note from Doctor Luo: Some truths of ancient Chinese medicine can’t be verified by modern statistics, but they are genuinely true. Remember: keep the mind calm, keep desires few, and stay away from harmful content — especially middle school and high school students; exposing them to that material brings no benefit at all. Try to keep ministerial fire from stirring, and the body will be far healthier. That is the most important lesson to take away today.
