Feet Too Swollen for Shoes, Pain Too Severe to Touch? Doctor Luo Tianyi’s Danggui Niantong Tang (Angelica Pain-Plucking Decoction) for Damp-Heat Leg Swelling, Gout & Ancient Jiao Qi

Patient search words: gout / swollen feet / swollen painful legs / jiao qi ｜ Medical terms: damp-heat bi syndrome · ancient jiao qi disease

Opening scene: a grand official whose feet were too swollen for shoes

The hero of this story is Master Nianhe Gong (粘合公) of the Central Secretariat of the Yuan dynasty. Anyone familiar with Doctor Luo Dalun’s series will smile at the name — this is an old patient of the Li Dongyuan school. Doctor Li Dongyuan had treated him while he was alive; now the master had passed away, and the official came knocking again — this time asking Doctor Luo Tianyi to carry on the treatment.

💬 Note from Doctor Luo: Notice this — from Doctor Li Dongyuan to Doctor Luo Tianyi, two generations of master and disciple treating the same patient. Classical medical books occasionally let you glimpse this kind of “fate between master, disciple, and patient,” and it is especially wonderful. Master Nianhe was a little over forty years old (nian si ju you yu) and burly of build (qu gan kui wu) — a stout, sturdy man.

That year, in the spring of the bingchen year (c. 1256 AD), the Yuan army was campaigning against the Southern Song, fighting its way down toward the Yangzhou region. As a Yuan official, Master Nianhe accompanied the army on the march. North of Yangzhou, his old trouble flared up again — his jiao qi attacked.

First, let’s clear up a misunderstanding: ancient “jiao qi” is not athlete’s foot

Some readers may ask: even an imperial physician treats athlete’s foot? We need to clear up a big misunderstanding right away — the “jiao qi” of ancient Chinese medicine has nothing whatsoever to do with what we call “Hong Kong foot” (athlete’s foot, tinea pedis) today.

💬 Note from Doctor Luo: In ancient times, jiao qi referred to a class of illness — weakness, numbness, swelling and pain of the lower limbs — caused by heavy dampness, heavy phlegm-dampness, and the like. In severe cases, the dampness can rush upward and attack the heart, bringing on whole-body illness and even endangering life. Many simplified-Chinese editions of ancient texts circulating online have been machine-translated with “jiao qi” rendered as “Hong Kong foot” — that is wrong. What the ancients meant by jiao qi is not the same disease as athlete’s foot at all.

So what disease does ancient jiao qi correspond to today? It is complicated: gout — many experts link gout to ancient jiao qi; and diabetic foot — in the late stages of diabetes, the toes ulcerate and rot, which also closely matches the descriptions in the ancient texts. Most ancient physicians believed the disease was connected to eating too well, being overweight, and having heavy dampness in the body.

How bad was it? Pain you couldn’t even touch, riding horseback barefoot

What did Master Nianhe’s attack look like? “Bian shen zhi ti wei zhong” — his whole body was slightly swollen. “Tong shou bu neng jin” — the swelling was so painful that the touch of a hand made it worse, and it grew steadily more severe. Worst of all were his feet and shins (the tibia): they swelled so much he could not put on shoes — putting on shoes was sheer agony.

💬 Note from Doctor Luo: Picture the scene: a high-ranking official, reduced to riding horseback barefoot, with two large bamboo tubes fitted into the stirrups so he could rest his feet inside them. How miserable! Only when he could no longer bear it did he come to ask Doctor Luo Tianyi (by then an imperial physician of the Taiyi Yuan, the imperial medical institute) for treatment.

Doctor Luo Tianyi’s diagnosis: classics in hand, seeing through at a glance

Doctor Luo Tianyi had a habit: cite the classics, keep the theoretical foundation solid. He first quoted the Huangdi Neijing (Yellow Emperor’s Inner Classic):

• “Yi yu zhong, fu zhong yu shang” — when water-dampness is extreme inside the body and the spleen and stomach are trapped by damp-heat, the whole body swells;
• “Zhu tong wei shi” — all painful conditions essentially belong to the excess (shi) category;
• “Xue shi zhe yi jue zhi” — when qi and blood are congested and stagnant, you must breach them and drain them out, the way you breach a riverbank.

The highlight: one jab of the three-edged needle — dark purple blood spurting two chi high

With the diagnosis clear, Doctor Luo Tianyi acted — with the three-edged needle (san leng zhen), several times, aiming precisely at the most swollen places and letting blood.

💬 Note from Doctor Luo: At the jab, the blood “spurted two chi and more high” (tu chu gao er chi yu) — it shot up about two feet into the air! Then it gradually streamed down to the ground like a thread, until fully half a sheng (about 500 ml) had been released — and the color was dark purple, almost black. What does the dark color tell us? That what was blocked inside was stagnant blood. Doctor Luo Tianyi’s reasoning: your qi and blood are congested, the whole body is blocked — so breach the most congested spot and let the qi and blood flow again. That is “xue shi zhe yi jue zhi” put into practice.

After the bloodletting, “qing zhi zhong xiao tong jian” — within a short while, the swelling subsided and the pain eased.

The prescription: Danggui Niantong Tang, a hefty one-and-a-half-liang dose

Next, Doctor Luo Tianyi wrote the formula: Danggui Niantong Tang (Angelica Pain-Plucking Decoction, 当归拈痛汤), at a dose of one and a half liang (about 45 g).

💬 Note from Doctor Luo: A dose of one and a half liang counts as relatively heavy in the prescribing habits of Doctor Luo Tianyi and his teacher Doctor Li Dongyuan — they usually reserved such large doses for treating sores and carbuncles or acute emergencies. That very night, this official — who had been in so much pain he could not sleep — slept wonderfully. The next day he took another dose, and the illness was simply cured — “ming ri zai fu er yu” (“a further dose the next day, and he recovered”).

Why was this formula so effective? Danggui Niantong Tang still appears in today’s Chinese formula textbooks — it is a very important formula. Where did it come from? It was created by Zhang Yuansu, the teacher of Doctor Li Dongyuan — Zhang Yuansu discussed its use specially in his own book; Doctor Li Dongyuan also recorded it in his, with the proportions slightly adjusted; and Doctor Luo Tianyi carried on using it.

Breaking down the formula: removing dampness on three fronts, plus clearing heat and supporting upright qi

Before explaining the formula, we need one piece of prescribing theory: “xuan ke qu yong, tong ke qu zhi” — use dispersing methods to open up blockage, use unblocking methods to get qi and blood moving again.

💬 Note from Doctor Luo: This comes from a book on prescribing methods, the Bencao Shiyi (Supplement to the Materia Medica). Some experts say it was written by Chen Cangqi of the Tang dynasty; Doctor Luo Dalun believes that is wrong — it should be the work of Xu Zhicai (徐之才), a famous physician of the Northern and Southern Dynasties. The book’s summary of ten prescribing methods — xuan (disperse), tong (unblock), bu (tonify), xie (drain), and the rest — exerted enormous influence on later generations, and Doctor Luo Tianyi constantly cited it in his prescribing. He then quoted the Neijing: “shi yin yu nei, zhi yi ku wen” — when dampness overflows within, treat it with bitter and warm medicinals to transform the dampness away.

Across the whole formula, dampness is attacked on three fronts:

Front one: wind herbs open the road (qianghuo, fangfeng, shengma, gegen) — the sovereign herbs

• Qianghuo (notopterygium): bitter and pungent; it penetrates the joints and conquers dampness (tou guan jie er sheng shi). The Jin-Yuan physicians were especially skilled with wind herbs — wind conquers dampness; once qi and blood move, the dampness can finally be expelled;
• Fangfeng (saposhnikovia root): sweet, pungent, and warm; it disperses the dampness lingering in the channels (san jing luo zhong liu shi). Qianghuo opens the joints, fangfeng travels the channels — paired together, channels and joints are unblocked at once;
• Shengma (cimicifuga) and gegen (kudzu root): bitter, pungent, and neutral; they are “the thin part of the stomach, the yang within yin,” with a medicinal nature that moves upward — they lift the water-dampness up and disperse it, keeping it from pooling below. This too is a working of “wind conquers dampness.”

Front two: strengthen the spleen and transform dampness (baizhu, cangzhu)

• Baizhu (white atractylodes): bitter, sweet, and warm; harmonizes the middle and conquers dampness, tonifying spleen-earth and controlling water-dampness;
• Cangzhu (black atractylodes): light and floating in nature, with a powerful, forceful qi; it specializes in removing the dampness between skin and muscle (cou li), and is strong at draining water (though slightly weaker than baizhu at tonifying the spleen). Used together, the two atractylodes both tonify the spleen and remove dampness — a stronger combination.

Front three: bland percolation to drain dampness (zhuling, zexie) These two are the assistant herbs — they promote urination and drain the water-dampness out through the lower passage, “guiding the stream and drawing it off” (dao qi liu yin).

Then two more groups of herbs:

• Clearing heat: Zhang Zhongjing said “dampness and heat combining makes the body vexingly painful (shi re xiang he ze shen fan teng)” — when dampness and heat are tangled together, the person is vexed and in pain. So he added the bitter-cold medicinals kushen (sophora root), huangqin (baical skullcap root), zhimu (anemarrhena), and yinchen (oriental wormwood) to clear damp-heat (“yi ku xie zhi” — drain it with bitterness; bitterness dries dampness);
• Supporting upright qi: danggui (Chinese angelica), renshen (ginseng), and gancao (licorice) — danggui is pungent and warm, letting qi and blood each return to their proper place so they no longer stagnate (the formula is named after it); renshen and gancao are sweet and warm, tonifying the spleen and stomach, nourishing upright qi, and shielding the stomach from injury by the bitter-cold medicinals.

💬 Note from Doctor Luo: Look at this formula — wind herbs scatter the dampness, the spleen is strengthened to transform dampness, bland herbs percolate the dampness away, plus clearing heat and supporting upright qi — the logic is exceptionally clear. Why must upright qi be supported? The root of heavy dampness lies in spleen-stomach deficiency: when upright qi is insufficient, dampness is able to settle. Renshen, baizhu, and gancao build the upright qi back up, and only then can the dampness truly be driven out.

Why is it named “Danggui” Niantong Tang? — supporting upright qi is the real key

The formula’s indications: damp-heat as the disease, vexing pain of the limbs, heaviness of the shoulders and back, discomfort of the chest and diaphragm, dampness flowing down to the calves with unbearable swelling and pain. Today, any pain and swelling caused by damp-heat in the body can use it — when gout attacks severely, many people turn to it; and various skin diseases (erythema nodosum, neurodermatitis, psoriasis), lumbar disc herniation, prostate conditions… search online for “clinical applications of Danggui Niantong Tang” and you will find it used for almost everything — precisely because its intent is clear and its construction ingenious.

💬 Note from Doctor Luo: Interestingly, this formula contains the most dampness-removing herbs, yet it is named after danggui — “nian” means to pluck or take something away, so “Danggui Niantong Tang” means “the pain is taken away as if plucked off.” Why not call it “Dispel Wind, Scatter Dampness, Pluck the Pain Decoction”? Because supporting upright qi is the key: once the dampness is removed, the channels are left empty; if you don’t nourish blood and support upright qi, the pathogen will slip right back in no time. It is the same reasoning behind Zhang Zhongjing’s placing Guizhi Tang (Cinnamon Twig Decoction) as the very first formula in the Shang Han Lun (Treatise on Cold Damage) — first regulate the spleen and stomach and build up the upright qi; once ying and wei are in harmony, the external pathogen can finally be cleared.

So what kind of damp-heat pain suits this formula? Doctor Luo Dalun teaches a simple tongue-reading method: a swollen, enlarged tongue body, a red tongue body (heat inside), a thick, greasy tongue coating with a slight yellow tint, and lots of saliva in the mouth (heavy dampness) — for any illness caused by damp-heat, especially damp-heat pain of the limbs, Danggui Niantong Tang works particularly well.

Bonus: the grand “four seasons pattern” system of this school of medicine

Finally, Doctor Luo Dalun also told us about the larger background: the master-disciple lineage of Zhang Yuansu, Doctor Li Dongyuan, and Doctor Luo Tianyi possessed a vast theoretical system — combining the four seasons, the four directions, and the thickness and thinness, yin and yang, of medicinals, using “the pattern of the four seasons” to regulate the body in correspondence with the ascending, descending, floating, and sinking of the qi movement of nature.

💬 Note from Doctor Luo: So sometimes the medicine is meant to move upward, sometimes downward — the ascending, descending, floating and sinking of herbs correspond to the rhythm of the seasons. The creator of this system was Zhang Yuansu, its great completer Doctor Li Dongyuan, and its practitioner Doctor Luo Tianyi. Unfortunately, part of this body of knowledge has already been lost; few people today master it — but for those who truly study it, it is a precious treasure of Chinese medicine.

Back to the case itself: such a severely ill patient, and Doctor Luo Tianyi settled it with one day of bloodletting and two doses of medicine. From then on, Master Nianhe trusted the master-disciple pair even more — he had sought treatment from the master while he lived, and after the master’s death he sought treatment from the disciple. The bond of fate stretched on for a long time.

💬 Note from Doctor Luo: The case record ends there; nothing more is written. But we can imagine that they were indeed good friends — a patient willing to entrust his body to two generations of master and disciple is, in itself, the most moving thing about the transmission of Chinese medicine.
