Opening scene: sweating a cold away — done wrong, it becomes a disaster

Catching a cold, breaking into a big sweat, and driving the cold pathogen out — that is probably what most people naively imagine. But the story the great master Doctor Xu Shuwei tells today is exactly the opposite: a merchant was sweated too hard, until his two hands crossed over his chest and pressed against his heart, his body swayed back and forth, and his heart was so frightened and restless it felt like he had been possessed.

💬 Note from Doctor Luo: Today we continue with the case records of Doctor Xu Shuwei, the Song dynasty master of classical formulas, and how he treated patients using the formulas of the Shang Han Lun (Treatise on Cold Damage). Xu Shuwei was a famous physician of the Northern–Southern Song transition. His Shang Han Jiu Shi Lun (Ninety Discussions on Cold Damage) is the earliest surviving medical casebook in Chinese history. It records not only “which formula was used” but also the fine art of “pattern discrimination” — Zhang Zhongjing was an extraordinarily careful observer, noting every detail of his patients’ symptoms, and that is precisely the foundation of pattern discrimination in later Chinese medicine.

Who was the patient? Eight or nine days of cold damage, and both hands pressed to the chest

The year was 1125 (the seventh year of the Xuanhe reign of the Northern Song), in the month of June, when the weather was scorching hot. In Jishui Tan there lived a merchant named Yucheng Nan, in the south of town. He had contracted cold damage (shang han), and eight or nine days had already passed. By this point he had developed a very particular gesture: his two hands were crossed and pressed over his chest, while his body swayed back and forth — his heart always felt uneasy, as if something terrible was about to happen at any moment.

Earlier, other doctors had been called in, and they all treated it as heart pain. It did no good. With no other option, the family finally sent for Doctor Xu Shuwei.

Doctor Xu Shuwei saw it at a glance: this is “cha shou zi mao xin” — hands crossed over the heart

Doctor Xu Shuwei arrived and, before even taking the pulse, took one look at the patient and knew what was going on. He said: look at his gesture — the two hands crossed and propped over the chest. This is exactly what Zhang Zhongjing described in the Shang Han Lun as “cha shou zi mao xin” (叉手自冒心) — the hands crossed over the heart!

💬 Note from Doctor Luo: These “casual gestures” matter enormously! A patient’s unconscious movements often reveal the real problem. Take the tongue: when a person sticks out a pointed tongue, that is liver qi constraint; when the tongue is plump and round, that is spleen deficiency. But some people, when they stick out their tongue, unconsciously tense it and make it round — you have to catch the split second when they start to withdraw it to see the tongue suddenly become pointed. That is the truth. A few days ago I was helping a friend examine a family member. In the photos the tongue always looked round, but in the video you could see that at the moment of withdrawal the tongue was sharply pointed. I said: this person has liver qi constraint and enormous stress. It turned out he worked at a famous accounting firm and screamed at his boyfriend every day — a frightening temper. The subtle details are where diagnostic skill lives.

What did Zhang Zhongjing say? “If after excessive sweating the patient crosses his hands over his heart, with palpitations under the heart and a desire to press on it, Guizhi Gancao Tang (Cinnamon Twig and Licorice Decoction) governs.” — When sweating has been excessive, the patient crosses both hands over the chest, the heart pounds uneasily, and he always wants to press down on it: treat it with Guizhi Gancao Tang.

And what did the patient himself feel? He said: xin xia zhui zhui ran (心下惴惴然) — a fearful, anxious feeling in the chest, thumping and thudding, with the rhythm all jumbled.

Why did a good sweat go so wrong?

Someone will ask: doesn’t cold damage call for sweating to push the cold pathogen out? How can sweating itself cause illness?

Doctor Xu Shuwei said the problem lies in sweating too much. In the Shang Han Lun, in the very first formula — Guizhi Tang — Zhang Zhongjing repeatedly warns: after taking the medicine, the body should be “moist with a fine, faint sweat all over” (遍身漐漐微似有汗) — just a light, even moisture is enough; never “sweat in great streaming rivulets” (大汗流漓). If the sweat pours down in sheets, “the disease will certainly not be cured” (病必不除) — the illness will not resolve, and the upright qi will be wounded besides.

💬 Note from Doctor Luo: There is a crucial idea in Chinese medicine here: sweating is not the goal; it is only a result. A faint sweat means the upright qi has returned, the qi and blood are moving normally, the fluids are full, and the body is warm — sweating is merely the sign of that state. It is not that the more you sweat, the more pathogen you drive out. Those practices of “drink some ginger-brown-sugar water, then bundle up and force a drenching sweat” may be fine for a sturdy constitution, but for a weak one they cause real trouble, with endless after-effects.

So what does a drenching sweat actually wound? First, the fluids are severely damaged — body fluids pour away. Second, qi escapes along with the sweat — Chinese medicine says “blood and sweat share the same source” (血汗同源): blood and sweat both arise from the body’s fluids, so excessive sweating injures the blood; and “qi is the commander of blood, blood is the mother of qi” (气为血之帅，血为气之母) — qi can only exist by attaching itself to blood. When blood is wounded, qi disperses with it. So after a great sweat, a person is not only deficient in yin fluids but deficient in yang qi as well.

Doctor Xu Shuwei also told a cautionary tale from the ancients: long ago there was a high minister who, just as he was to handle the grand ceremony of a new emperor’s enthronement, caught a cold. A famous physician was called, and said: your upright qi is insufficient. Sweating is possible, but it will shorten your lifespan. The minister, thinking only of getting the job done, quoted the saying “if I can hear the Way in the morning, I am content to die that evening” — never mind next year, let me sweat! So the ground was heated, pottery tiles were laid on it, and the man was steamed into a drenching sweat. The next day the cold was indeed cured, and he happily went off to complete the enthronement business. The following year, he died.

The formula, unpacked: just two herbs — Guizhi Gancao Tang

Zhang Zhongjing’s formula is wonderfully simple: only two herbs — gui zhi (cinnamon twig) and zhi gan cao (honey-fried licorice) — with the cinnamon twig at twice the dose of the licorice. Do not underestimate it: this is the master formula for restoring heart yang, a “parent formula” — its shadow runs through later formulas such as Zhi Gancao Tang (Honey-Fried Licorice Decoction).

💬 Note from Doctor Luo: What is gui zhi? The bark from the lower part of the cinnamon tree is rou gui (cinnamon bark); the thin twigs from the upper part are gui zhi (cinnamon twig). Gui zhi warms yang and frees the channels, and it is especially good at opening the heart vessels — it appears in Guizhi Tang, Zhi Gancao Tang, and many others. Paired with honey-fried licorice — zhi gan cao — its job is to tonify qi and protect the vessels: it fortifies the spleen and stomach, supports the upright qi, and above all can restore the rhythm of the heartbeat. Modern research has confirmed that honey-fried licorice has hormone-like effects and can regulate arrhythmias. How the ancients discovered these things on their own is truly remarkable.

Doctor Xu Shuwei went further: spleen yang, kidney yang, and heart yang adjusted together

The patient had sweated excessively and his heart yang was insufficient — was Guizhi Gancao Tang alone enough? Doctor Xu Shuwei did not stop there. He adjusted more comprehensively — on top of Guizhi Gancao Tang, he added two more formulas:

• Huangqi Jianzhong Tang (黄芪建中汤, Astragalus Fortifying the Middle Decoction) — to tonify spleen yang. This formula comes from the Jingui Yaolue (Essential Prescriptions of the Golden Coffer): it takes Guizhi Tang, doubles the white peony, and adds astragalus and maltose syrup, specifically to restore spleen-stomach function. Doctor Luo Dalun himself often uses it for stomach ulcers — especially the kind driven by bad emotions and liver qi attacking the stomach.
• Zhenwu Tang (真武汤, True Warrior Decoction) — to tonify kidney yang. Kidney yang is the root of yang qi for the whole body.

Spleen yang, kidney yang, and heart yang — all three formulas together, rotated back and forth. When the yang qi of the three burners was restored, the patient’s palpitations and dread gradually settled and leveled out.

💬 Note from Doctor Luo: Doctor Xu Shuwei used the classical formulas with wonderful flexibility — he did not stubbornly stick to “Guizhi Gancao Tang and done.” He went to the root: restore the spleen yang, apply the kidney yang, and tonify the heart yang on top. It is like boiling water: pouring hot water on the lid is not enough — you have to add fuel to the stove. The spleen and kidneys are the fuel in that stove.

What does heart-yang deficiency feel like?

What exactly does heart-yang deficiency feel like? Doctor Luo Dalun says he experienced it himself while studying in his youth: a constant feeling of fluttering and dread in the chest, as if some disaster was about to strike; when someone slapped the table, his heart would give a sudden “clunk”; at night he could not sleep peacefully, and even wondered whether he had been possessed. Only after slowly building his upright qi back up did the feeling disappear.

People with heart-yang deficiency tend to have cold extremities, a pale face, cold sweats, a cold aching heart, and easy palpitations. If the heart-yang deficiency is severe, one must add larger doses of yang-warming herbs; if it is merely palpitations and hands pressed to the chest after excessive sweating, Guizhi Gancao Tang is generally enough.

💬 Note from Doctor Luo: When heart yang is insufficient, a person’s “spirit” (hun po) also becomes unsettled — there is a constant sense of being dazed and disconnected. At such times you can add some ren shen (ginseng) — ginseng settles fright and calms the spirit; once the upright qi is fully tonified, those dazed feelings vanish on their own. If fluids are also insufficient, add mai dong (ophiopogon) to replenish them. The later formula Zhi Gancao Tang (Honey-Fried Licorice Decoction) is in fact a formula that tonifies both yin and yang, both qi and blood: gui zhi and gan cao warm yang, while e jiao (donkey-hide gelatin) and mai dong nourish yin — a two-way balance. And a side note: the huo ma ren (hemp seed) in Zhi Gancao Tang was used by the ancients to loosen the bowels; American research now shows it can repair damaged heart muscle cells — we are still chasing after our ancestors! The wisdom of the old masters is a true treasure.

What to take away

First, do not sweat recklessly, and do not sweat excessively. A robust person can take a strong sweat (the Ma Huang Tang pattern, for example) — but how many truly robust people are there these days? For a weak constitution, a faint sweat is enough. Sweating must have its measure — this is what Zhang Zhongjing urged again and again.

Second, you have learned a formula: Guizhi Gancao Tang — two herbs that restore heart yang. When palpitations and hands pressed to the chest follow excessive sweating, use it; the original formula brings results.

Third, you have learned Doctor Xu Shuwei’s approach: warm spleen yang, tonify kidney yang, and warm heart yang together — a more comprehensive and steadier way to restore the body.
