Cold Exposure, Irregular Periods, Painful Menstruation, Prolonged Bleeding? The Sage’s Wen Jing Tang (Warming the Channels Decoction) from the Jin Gui Yao Lue: Warm the Yang, Dissolve Stasis, Nourish the Blood
Opening: Yesterday we talked yam; today we return to “the cold of women”
For the past few days, Doctor Luo Dalun’s series has been about women catching cold. Yesterday he inserted a side lecture on Huai yam; today he returns to the main topic.
💬 Note from Doctor Luo: Yesterday I jumped aside to talk about Huai shan yao (Huai yam). Because ever since we discussed Zhang Xichun’s case records, everyone has noticed how heavily Zhang Xichun used Huai yam — why do I love it so much? I learned it all from Zhang Xichun. Read his cases for long enough and you’ll see: whenever he supported the upright qi, he paid special attention to the spleen and stomach, so he used Huai yam constantly, and in large doses — often one liang (about 30 g) or more. For aftercare he would almost always grind Huai yam into powder, cook it into a paste, add a little sugar, and have the patient eat it as a snack. A physician of Zhang Xichun’s standing — at that time arguably the number one doctor in all of China — attached this much importance to yam. I think there must be good reason.
That “yam interlude” also produced a story of Doctor Luo’s own: he traveled to Henan specially to investigate and introduced everyone to dao-di (authentic) Huai yam — grown locally, without pesticides, chemical fertilizer, growth promoters or herbicides, exactly like what the ancients ate. Many readers wrote in saying they had benefited from it, and Doctor Luo said the messages moved him.
💬 Note from Doctor Luo: I may have no other contribution to Chinese medicine, but introducing this authentic Huai yam to everyone and guiding local farmers to grow this pesticide-free, high-quality yam identical to what the ancients ate — I think that is a small contribution. Why bring it up again now? Because this year the qi of heaven and earth has shifted in a very unusual way, so I want everyone to consolidate their upright qi and be ready for all sorts of changes in the weather.
Where does a woman’s cold really come from? — Blood deficiency is the first gate
Back to the main topic. When a woman catches cold, is it really as simple as drinking cold water and eating ice cream? Doctor Luo says that is the external cause; the true reason women are so vulnerable to cold is internal — something inside her own body has gone wrong first.
💬 Note from Doctor Luo: For women, the most common problem is blood deficiency — blood shortage. Because of their unique physiology and functions, women are especially prone to blood deficiency. Once your blood is deficient, your channels become empty; then when the outside temperature drops, you catch cold far more easily than others — and once that cold pathogen enters, it is hard to expel.
So the pattern of the past few days has been blood deficiency and yang deficiency tangled together — and in fact blood deficiency is often the root: once you catch cold, qi and blood stop flowing smoothly, which makes blood deficiency worse; and once yang is deficient, the power to generate and lift is weakened, which also deepens the blood shortage. That is how the vicious cycle turns.
💬 Note from Doctor Luo: For this kind of condition, I once introduced an ancestral formula called Jiao Ai Tang (Ass-Hide Glue and Mugwort Decoction). It is the prototype of Si Wu Tang (Four Substances Decoction), and Si Wu Tang is the master formula for nourishing blood — so Jiao Ai Tang is the “master of the master”: its strategy is to nourish blood and warm yang at the same time.
Today, the second pattern: blood stasis — a concept every woman must know
Besides blood deficiency, what problem do women run into especially often? Blood stasis (yu xue).
💬 Note from Doctor Luo: What is blood stasis? It is impaired, sluggish blood circulation. Women are especially prone to it, and it does tremendous damage to a woman’s body — again because of their unique physiology: the process of giving birth easily creates stasis; and if you catch cold during your period, that can also create stasis. So blood stasis is a concept every woman must understand.
Where does blood stasis come from? — Five sources, and don’t miss a single one
How does blood stasis form? Doctor Luo listed five sources, and every one maps onto modern women’s lives.
First: trauma. All kinds of injuries and gynecological surgery produce stasis; childbirth itself leaves stasis behind, and now that so many births are cesarean, poorly healed incisions make stasis even more likely.
Second: anger. Few people expect this one — it is called qi stagnation leading to blood stasis.
💬 Note from Doctor Luo: The liver governs free flow and keeps qi and blood moving smoothly. But when you get angry, your liver qi becomes constrained, qi and blood can no longer circulate — and stasis forms. Qi stagnates, then blood stagnates. Because modern people have endless chances to be angry and frustrated, modern women develop blood stasis at a staggering rate. Take nodules — thyroid nodules, breast nodules and the like: many of them are probably linked to anger. These days almost everyone who gets a checkup is told they have some nodule or other. A nodule is essentially a blocked spot — and it may well trace back to emotional frustration and anger. So regulating your emotions is absolutely critical.
Third: qi deficiency. Qi is the force that pushes blood along.
💬 Note from Doctor Luo: When qi is sufficient, the blood flows smoothly — the pump has strength and the blood moves freely through the vessels. When the pump loses its strength and movement stumbles, blood tends to stall inside the vessels. Many elderly people have stasis precisely because their upright qi is depleted. So when treating stasis, we usually also regulate qi — and often tonify qi. Dissolving stasis generally means adding qi tonics on top of invigorating the blood and freeing the channels.
Fourth: blood deficiency. Blood deficiency also produces stasis. Doctor Luo offered an analogy:
💬 Note from Doctor Luo: Think of a river. When the water is plentiful, it flows normally; after a drought the water level drops, and the current breaks into disconnected pools — here a pond, there a dry riverbed. The body’s qi and blood are the same: when blood is sufficient, the channels run normally; when blood is deficient, some sections simply stall because the flow can no longer connect.
Fifth: cold. Blood is a fluid, and fluids congeal when cold.
💬 Note from Doctor Luo: Like oil — when it turns cold it gets sticky and stops flowing. Many girls acquired their stasis exactly this way: dressing too lightly in cold weather; as students, not knowing any better, washing their hair in cold water, drinking cold water, and after exercise gulping down icy water — “glug, glug, glug.” Now they pay for it: agonizing cramps at every period. So cold and stasis almost always arrive together.
Doctor Luo added one more image, the “boulder blocking the pipe”: once stasis exists, some places have too much blood and others too little — which is why blood deficiency and stasis so often appear together. All these factors cause each other and reinforce each other — when qi and blood weaken you catch cold easily; cold makes stasis worse; stasis makes the deficiency worse.
Don’t treat with a one-track mind: warming the yang alone is not enough for most women
Once the mechanism is clear, the treatment strategy follows — and here lies the most common mistake: using only one method.
💬 Note from Doctor Luo: Say I just do moxibustion — but have I accounted for your blood deficiency? No blood nourishing, right? Say I only drink Fu Zi Tang (Aconite Decoction) — the other factors are not addressed. Warming yang alone works for some people — for instance, men. But for most women this is not enough. The warming approach is certainly correct — but wouldn’t it be better to add something that nourishes blood, something that dissolves stasis? Because whenever yang is deficient, it inevitably disturbs the menses, leukorrhea, pregnancy and childbirth, dragging in all the other factors.
The sage’s answer: Wen Jing Tang — one formula that thinks of everything
So what do we do? Doctor Luo’s answer today: a classic Zhang Zhongjing formula — Wen Jing Tang (Warming the Channels Decoction) from the Jin Gui Yao Lue.
💬 Note from Doctor Luo: See why Zhang Zhongjing is called the medical sage? He thought of every possibility, anticipated every problem — that is why his formulas are so classic. Wen Jing Tang treats deficient cold in the Chong and Ren vessels: a woman who has caught cold — especially cold in the uterus, deficient cold in the Thoroughfare and Conception vessels — with blood stasis blocking the way. In today’s language: this woman is both cold-exposed and yang-deficient, and on top of that she has stasis — and where does the stasis gather? In the uterus, in the lower abdomen.
What does the original text say? “She has previously miscarried, and blood stasis remains in the lower abdomen” — how do you know there is stasis? Dry lips and mouth.
💬 Note from Doctor Luo: The signs include dry lips and a dry mouth — that dryness is precisely the mark of stasis. What else? Fever toward dusk — the body starts running hot in the afternoon and evening; cramping urgency in the lower abdomen, pain inside; abdominal fullness, a bloated belly; and hot, restless palms. These symptoms are the portrait of this pattern.
And how does menstruation behave in a woman with this combination of “cold + stasis + blood deficiency”?
💬 Note from Doctor Luo: Dripping that will not stop — the period leaks on and on, with dark blood carrying clots, which indicates stasis; or scanty, sluggish flow; or periods arriving early, arriving late, or dragging past their time — the whole cycle is chaotic; some women have two periods in one month; others bleed without stopping. All of these can be cold combined with stasis. Today we use this formula’s strategy for dysfunctional uterine bleeding, chronic pelvic inflammatory disease, dysmenorrhea, infertility and more — as long as the pattern is deficient cold in Chong and Ren with stasis, this formula’s thinking applies.
Formula breakdown (1): wu zhu yu, gui zhi, sheng jiang — drive the cold out
How is the formula built? Start with the main warming force.
💬 Note from Doctor Luo: The most important herb is wu zhu yu (evodia fruit). It warms the yang and disperses cold. You know, China had no chili peppers before modern times — what did cooks use for seasoning? Mostly Sichuan pepper — what we call chuan jiao — and also wu zhu yu, because its flavor is so strong. Then gui zhi (cinnamon twig) warms the yang and frees the channels: you have stasis, don’t you? Gui zhi warms the yang and opens the network. These two are the backbone of the formula — one warms the yang, the other frees the channels and dissolves stasis. Add a third herb, sheng jiang (fresh ginger). With these three together, your yang deficiency with cold is basically resolved.
Formula breakdown (2): dang gui, bai shao, chuan xiong — Si Wu Tang “missing one ingredient”
The stasis frozen by cold must be dissolved, and the blood-deficient foundation must be nourished.
💬 Note from Doctor Luo: Next comes dang gui (Chinese angelica root), which nourishes blood and frees the channels; bai shao (white peony root), which nourishes yin and blood, astringes the liver and softens it; and chuan xiong (Sichuan lovage root), which nourishes blood, frees the channels, and moves the qi within the blood. Dang gui, bai shao and chuan xiong — add shu di huang (prepared rehmannia) and you have the complete Si Wu Tang. Why is rehmannia left out here? Because prepared rehmannia is slightly sticky and obstructing, which may hinder the freeing of the channels. But I think the formula can be adjusted — if blood deficiency is truly severe, you may add it.
Formula breakdown (3): ren shen and e jiao — tonify qi, then “catch” the blood
One cause of stasis is qi deficiency — nourishing blood alone is not enough; you must tonify qi.
💬 Note from Doctor Luo: Why ren shen (ginseng)? As I said earlier, people with stasis are often qi-deficient — their upright qi is insufficient, leaving no force to push the blood, so it stalls. So alongside nourishing the blood I add ginseng to tonify qi — tonifying both qi and blood. Qi generates blood, and blood carries qi. Once qi is tonified, more blood is generated, and the freeing of the channels works even better.
Now e jiao:
💬 Note from Doctor Luo: E jiao (ass-hide glue) nourishes blood and stops bleeding. Zhang Zhongjing was treating the dripping pattern — menstrual bleeding that would not end — so he used e jiao to stop the blood. If you don’t have that problem, you can leave e jiao out and simply keep the blood-nourishing herbs.
Formula breakdown (4): mai dong and dan pi — moisten dryness, clear deficiency heat
Warming herbs used heavily create dryness, and blood deficiency easily breeds deficiency heat — Zhang Zhongjing thought of both.
💬 Note from Doctor Luo: Mai dong (ophiopogon root) moistens dryness and checks wu zhu yu’s heat — use too much evodia and you feel dry lips, even blisters at the corners of the mouth. Mai dong nourishes yin and generates fluids, acting as a counterbalance to the drying heat of evodia while replenishing the body’s fluids — because this type of patient is short of both blood and fluids. Then dan pi (moutan bark): when blood is deficient, dry heat and a little deficiency heat tend to arise, and dan pi clears it — at the same time it drains liver fire, since one cause of stasis is emotional frustration with liver fire.
Formula breakdown (5): ban xia — guiding the action down to the lower abdomen
The last herb puzzles many people — why ban xia (pinellia)?
💬 Note from Doctor Luo: Ban xia moves qi and transforms phlegm, and its nature is to descend. Remember what I taught about Huang Yuanyu — in his formulas fu ling (poria) raises the qi of the left side, ban xia lowers the qi of the right side, and gan cao (licorice) sits in the middle — every formula is really about regulating the movement of qi. This formula treats disease of the lower abdomen; the illness sits in the lower belly, so the herbs must travel downward — where do I want the blood invigorated and the channels freed? Down below, moving through the lower body. So ban xia’s presence carries deep meaning.
This “descending” herb hides a true story:
💬 Note from Doctor Luo: Beijing University of Chinese Medicine once had an elder named Wang Mianzhi, who taught formula studies brilliantly — when I was a student I was captivated by his lectures. Professor Wang said that in his youth he didn’t understand this herb either and thought ban xia was useless. He was treating a woman with yang deficiency and stasis using this very formula — but without ban xia. The blood, once freed, came pouring out from above — nosebleeds. Vicarious menstruation: the period was coming out through the nose. In a flash he understood: ban xia in Zhang Zhongjing’s formula is truly indispensable. The moment he added ban xia back, her periods returned to normal and the stasis dissolved. Every single herb in Zhang Zhongjing’s formulas has its reasoning — do not casually remove them.
The sage’s strategy: one formula that blocks every route of stasis
Why is Zhang Zhongjing the medical sage? Doctor Luo used the image of a martial-arts master.
💬 Note from Doctor Luo: You caught cold and have stasis; you’re yang-deficient and have stasis — I give you wu zhu yu, gui zhi and sheng jiang to warm the yang. Blood deficiency — I give you dang gui, bai shao and chuan xiong to nourish the blood, and if you like add prepared rehmannia to complete the Si Wu Tang. On top of the stasis there’s some qi deficiency, no force to push — I add ren shen. There’s liver fire, women get angry easily — I add a little dan pi to drain liver fire. The stasis sits in the lower abdomen — I add ban xia to guide the qi downward. And the formula runs a bit hot — I add mai dong, in a generous dose, to moisten dryness, help nourish blood and supplement fluids. In one formula, every aspect of a woman who caught cold and developed stasis is accounted for. Like a martial-arts master’s opening move, with several variations — I’ve covered all your possibilities at once. Truly worthy of the title “medical sage.”
Every later Wen Jing Tang derives from this one:
💬 Note from Doctor Luo: There are many formulas called Wen Jing Tang in later literature — the Tai Ping Hui Min He Ji Ju Fang, the Fu Ren Da Quan Liang Fang, and many other medical books each have their own Wen Jing Tang. But they all build on this formula, using it as the foundation for their own additions and subtractions. So this is the master formula; Zhang Zhongjing set out the whole strategy for us.
How to use it yourself: modifications and foot baths
Can an ordinary person use this formula? Doctor Luo gave very practical advice.
💬 Note from Doctor Luo: If your anger is especially prominent, add a little rose bud, chen pi (tangerine peel), xiang fu (cyperus) — anything that moves qi. The ideal is to have a TCM practitioner prescribe and adjust it for you. But if you can’t see a practitioner and your symptoms all line up — irregular periods, a history of cold, genuine yang deficiency, and blood stasis — then what? Buy the herbs anyway and soak your feet in the decoction. Foot soaking works just as well. Once you understand the strategy, caring for your body becomes simple.
Closing: women should understand their own bodies better
At the end, Doctor Luo restated the theme of the whole series.
💬 Note from Doctor Luo: Don’t underestimate a woman’s cold — the mechanism inside it is quite complex. I talk about this every day so that, having heard it, you understand your body better: first, so you can prevent problems better; second, so you can adjust better. I hope women understand their bodies more, know how to regulate themselves, and gradually grow healthier — expel the cold pathogen, dissolve the stasis, build up the yang, tonify the qi, nourish the blood fully. Then your body will certainly be healthier. Next week we’ll continue on how to regulate a woman’s cold and take this theme to its full depth.
