Restless Insomnia, Racing Heart, Forgetfulness? Doctor Luo Dalun on Tian Wang Bu Xin Wan (Heavenly King Tonify-the-Heart Pill): Nourish Yin, Nourish the Heart, for Heart-Yin Deficiency
What patients search for: restless insomnia / racing heart / heart pounding / forgetfulness / easily startled Medical terms for this condition: heart-yin deficiency · heart-kidney yin deficiency · restless insomnia from deficiency · palpitations with a pounding, frightened heart (zheng chong)
Opening: Summer has arrived — the season the heart fears most
In Chinese medicine, the five organ systems correspond to the four seasons, and summer corresponds to the heart. In summer the heart fire runs strong, and if a person’s internal environment is not stable, problems surface — people with yang deficiency actually get through summer fairly comfortably: the weather is warm and they feel fine. But people with yin deficiency run into trouble as soon as summer comes, and the trouble lands most often on the heart. That is why so many heart patients — those with heart and lung conditions — fear summer more than any other season.
💬 Note from Doctor Luo: In summer you should nurture the heart. Earlier I introduced a formula called Zhu Sha An Shen Wan (Cinnabar Calm-the-Spirit Pill) — that is for when heart-yin is deficient, fire is riding along with it, and the person has started to become manic, agitated and disordered. Zhu Sha An Shen Wan is led by zhu sha (cinnabar), which is heavy and settling; it pairs a little huang lian (coptis) to clear fire and sheng di (raw rehmannia) to nourish yin. You cannot take this medicine for long, because it contains cinnabar. But when someone is in that state of panic, fear and agitated sleeplessness, I generally have them take Zhu Sha An Shen Wan for a day or two first — to settle that frantic, frightened, fearful state of the spirit — and then move on to nourishing the heart.
After settling the spirit, it is time to nourish the heart: Tian Wang Bu Xin Dan
Once the panicky spirit has been settled, what comes next? Tonify the heart, nourish the heart. Doctor Luo next introduces two heart-nourishing formulas, and the first is Tian Wang Bu Xin Wan — the formula was originally called Tian Wang Bu Xin Dan (Heavenly King Tonify-the-Heart Pill).
💬 Note from Doctor Luo: My usual practice is this: take Zhu Sha An Shen Wan for one day, then follow it with several days of Tian Wang Bu Xin Dan. The two formulas share roughly the same line of thinking, but Tian Wang Bu Xin Dan contains many more yin-nourishing ingredients — its main thrust is nourishing yin.
Where does the formula come from? Ming-dynasty imperial physician Xue Lizhai
The origin of Tian Wang Bu Xin Dan is interesting, and it is connected to a famous work on gynecology.
💬 Note from Doctor Luo: This formula was collected by the famous Ming-dynasty physician Doctor Xue Lizhai. Xue Lizhai was the director of the Imperial Academy of Medicine — he treated the emperor. He wrote a book called the Annotated Edition of the Fine Formulas for Women — its base text was the Comprehensive Fine Formulas for Women written by the Song-dynasty physician Chen Ziming, which gathered many gynecological formulas; Xue Lizhai annotated it, expanded it and developed it further. It is in this book that Tian Wang Bu Xin Dan appears.
What does it treat? The whole chain of problems from heart-kidney yin deficiency and depleted blood
Tian Wang Bu Xin Dan nourishes yin and blood, and it specializes in spirit agitation caused by yin deficiency — all kinds of heart problems, and the emotional and mental disturbances that follow. Where is the root? Heart-kidney yin deficiency and depleted yin blood.
💬 Note from Doctor Luo: The symptoms of yin deficiency come one after another. First, insomnia — the insomnia of heart-yin deficiency is called xu fan bu mei (restless sleeplessness from deficiency): you lie in bed tossing and turning, unable to fall asleep; the more agitated you feel, the less you can sleep — that is restless insomnia with palpitations. Then there is palpitation — the heart thumps and pounds out of rhythm, and you can feel it yourself; today we would say this is connected to premature beats. Next comes forgetfulness: when heart-yin is insufficient, the capacity of the heart-spirit begins to decline — someone who normally has a good memory may start to forget; problems you could usually think through, you can no longer think through. I know this from personal experience — you only truly understand many conditions after you have felt them yourself. When the heart-spirit is insufficient, people who usually speak fluently will, when they stand up to speak in a weakened state, stammer and lose their train of thought mid-sentence — something you know perfectly well, you simply cannot recall. What else do men have? Nocturnal emissions — seminal loss during dreams. And there is a classic symptom called zheng chong: everyone else in the room is fine, then someone suddenly slams a table, and your heart leaps and pounds — you are terrified. That is the heart being flustered and unsettled — a sign of insufficient heart qi and heart spirit.
What about the tongue? Red tongue, thin coating, fast pulse
What does the tongue of a person with heart-yin deficiency look like? You can see it at a glance.
💬 Note from Doctor Luo: Such a person’s tongue is bright red, flushed, with a very thin coating — you can even see red grains on it. This tongue will never be pale-white. Instead it should be red tongue, thin coating, fast pulse.
Breaking down the formula: what each ingredient does
What is the most important ingredient in this formula? Sheng di (raw rehmannia) — and it is used in large quantity.
💬 Note from Doctor Luo: When I discussed Zhi Gan Cao Tang (Honey-Fried Licorice Decoction) I also paired large amounts of sheng di. What does sheng di do? It tonifies kidney yin. Kidney water can rise to moisten heart fire, keeping the heart fire from flaring alone. The heart belongs to fire, the kidney to water, and water and fire should be in harmony (ji ji) — water rises to cool the heart fire so it does not overheat; heart fire descends to warm the kidney water so it does not grow too cold. This is what the ancients called water and fire in mutual harmony, the best possible arrangement. The heart fire blazes too strongly because yin is insufficient — kidney water is insufficient — so you must tonify heart yin. The formula pairs xuan shen (figwort root) — xuan shen is cool, and it assists sheng di in nourishing water to control fire; its special quality is that it can draw kidney water upward. That is why in many throat conditions, when yin deficiency leaves the throat dry, physicians tonify kidney yin and pair in a little xuan shen, drawing kidney water up to moisten the throat — moistening dryness, nourishing yin, clearing fire. Tian dong and mai dong (asparagus root and ophiopogon root) nourish lung-kidney yin, especially lung yin — the lungs belong to metal, and excessive fire harms metal, so such patients usually have lung-yin deficiency as well; once lung yin is fully nourished, lung qi descends, and heart fire follows it downward. Lung yin in the upper burner is a major force that keeps heart fire in check. Below you replenish with kidney water, above you bring down with lung yin — and the fire in the heart channel cannot blaze too fiercely.
Then come three routes — nourishing blood, tonifying qi, and calming the spirit:
💬 Note from Doctor Luo: Dan shen (salvia) nourishes blood and frees the channels — “one dose of the Dan Shen drink equals the Si Wu Tang (Four Substances Decoction)”; it is the equivalent of a Four Substances Decoction for nourishing blood. When heart fire blazes too fiercely it scorches yin fluids, and when yin fluids are insufficient blood stasis easily forms — so dan shen both nourishes blood and invigorates it. It is paired with dang gui (Chinese angelica), which tonifies blood and also invigorates it. Then ren shen (ginseng) — when heart blood is insufficient, heart qi is also wounded; the moment someone slams a table you jump out of your skin, but once qi is tonified and the upright qi of the heart is sufficient, this symptom disappears. Qi generates blood, so ginseng plays a very important role here. Fu ling (poria) is paired in to dry dampness. Bai zi ren (arborvitae seed) and yuan zhi (polygala) calm the spirit and settle the heart — these two appear in many spirit-calming formulas. Yuan zhi can link heart and kidney: when heart fire and kidney water cannot communicate, yuan zhi gets them circulating again. Wu wei zi (schisandra) tonifies the five organs, has an astringent action and also calms the spirit; with restless sleeplessness, boil a little wu wei zi in water and drink it — it is very sour, it gathers and settles the spirit, and you may fall asleep. Suan zao ren (sour jujube seed) nourishes the heart, calms the spirit and nourishes blood — its spirit-calming effect is excellent; for restless sleeplessness, brew some powdered stir-fried suan zao ren and drink it, and it too can calm the spirit.
The last two ingredients, which finish the formula, each have their own special role:
💬 Note from Doctor Luo: Jie geng (platycodon) is the ingredient that carries medicine upward — it lifts the medicinal action into the upper burner, because the disease this formula ultimately treats is in the heart channel of the upper burner. When the medicine is finished, the outside is coated with a little zhu sha (cinnabar) powder, also for its heavy, settling action. Look at this formula: yin-nourishing, blood-nourishing, qi-tonifying, spirit-calming — and finally a coat of cinnabar to settle the spirit heavily. Compared with Zhu Sha An Shen Wan it has many more yin-nourishing ingredients — it is more comprehensive.
Bonus story: knocking the gallbladder channel until you knock out your sleep — what to do?
Doctor Luo once told a real story that beautifully illustrates the principle of “nourishing blood and nourishing yin.”
💬 Note from Doctor Luo: A friend read in a book that knocking the gallbladder channel is good for you, so he knocked it every day — and instead, the moment he knocked it, he could not sleep; that very night he lay awake. What was going on? This person had little blood — liver-blood deficiency. The blood was already insufficient; when he knocked the channel, the channels opened and the blood began to circulate, but there was not enough blood to go around, and at night there was no blood to nourish the heart — so he could not sleep. What to do? I told him: boil a little wu wei zi (schisandra) in water, boil a little shan yu rou (cornus fruit) too, and use that water to wash down powdered stir-fried suan zao ren (sour jujube seed) — nourishing blood and nourishing yin. Once blood and yin are fully replenished and qi and blood move through the channels, you can knock all you like. He drank it, and the response was immediate — he fell right asleep. When you understand the principles of Chinese medicine, you can solve such problems with very simple methods.
Who is this for? Who should avoid it?
Who should take Tian Wang Bu Xin Wan? Remember four characters: yin deficiency, heart-yin insufficiency.
💬 Note from Doctor Luo: For anyone with yin deficiency accompanied by heart-channel problems — red tongue, thin coating, dryness, thirst, dry eyes, hot palms and soles, plus restless insomnia, forgetfulness, palpitations, zheng chong (a pounding, frightened heart) — this formula is worth considering. The ready-made patent medicine is called Tian Wang Bu Xin Wan, and it is available in pharmacies. But remember: pregnant women should not take it casually — only under a doctor’s guidance; and this formula treats illness — it is not for health maintenance. When these problems really appear, the heart responds noticeably and sleeplessness is deeply miserable — and this formula can resolve it.
At the end, Doctor Luo leaves us with a teaser: how should you protect your heart in summer? In the coming lectures he will gradually introduce all kinds of summer heart-nourishing formulas.
💬 Note from Doctor Luo: Dear friends, that is all for today. As for how to protect the heart in summer, we will introduce all kinds of formulas one by one in the days ahead — see you next time!
