Adenophora & Polygonatum Duck Soup
Adenophora & Polygonatum Duck Soup
A classic lung-nourishing soup that clears deficiency heat and soothes chronic dry cough.
Ingredients
- 1/2 to 1 whole duck
- 50g adenophora root (sha shen)
- 50g polygonatum root (yu zhu)
- 3 slices ginger
- 1 tbsp Shaoxing wine
- Salt to taste
How to Prepare
- Clean and chop the duck into large pieces. Blanch in boiling water, then rinse.
- Place duck, ginger, and Shaoxing wine in a clay pot. Cover with water and simmer on low heat for 30 minutes.
- Rinse adenophora and polygonatum roots. Add to the pot.
- Continue simmering on low heat for 2 hours.
- Season with salt. Serve the broth and meat together.
Why This Works
Adenophora (sha shen) and polygonatum (yu zhu) are a classic TCM pair for nourishing lung yin and clearing deficiency heat. Duck is cool in nature, making it ideal for reducing internal heat while replenishing fluids.
Modern Perspective
Duck meat is rich in selenium and B vitamins. Adenophora contains polysaccharides with immune-modulating effects, while polygonatum is studied for its antioxidant and anti-inflammatory properties.
Why This Combination
A cooling, moistening soup, and it is the answer to a very specific dryness rather than a general one. Duck is cooling in the Chinese material rather than warming, which distinguishes it from chicken, and the two herbs here are the classical pair for the dry version of a lung pattern: adenophora and polygonatum are both sweet, both cooling, and both specifically moistening. Lily bulb would sit naturally alongside them, which is why the soup is often described in the classical material as being for a dry cough and a dry throat rather than for lung qi weakness. The practical translation is a soup for someone who is hot, dry, and thin — dry cough, thirst for small sips, dry skin — and who would be made worse by the warming, tonic recipes elsewhere on this site. The whole dish is a cooling, nourishing one and it should be taken cool or lukewarm.
What Each Ingredient Is Doing
Dishes are combinations, not lists, and the reason for including an ingredient is often not the one you would guess from the name. Here is what each one is actually contributing.
- Duck
Cooling rather than warming in the framework, which is what distinguishes this from a chicken soup. Duck fat is also a good source of fat-soluble vitamins on ordinary grounds.
- Adenophora root (sha shen)
Sweet, cooling, and moistening. One half of the classical pair for a dry lung pattern, and it is a genuine medicine rather than a food.
- Polygonatum (yu zhi)
The other half of the pair. Nourishes the yin and generates fluids, and it is what makes the soup moistening rather than merely cooling.
A small amount only. This is a cooling soup and a large amount of ginger would be working against it — a couple of slices to cut the duck fat is right.
- Rock sugar or pear
A little sweetness, and pear is the more classical version. Either softens what is otherwise a slightly medicinal-tasting broth.
The Properties of This Dish
The three properties each of these ingredients carries, so you can see what the dish as a whole adds up to. The full profile for each is below the table.

| Ginger in Chinese Medicine | 🔥 Warm | Pungent | Lung, Spleen, Stomach |
The Key Ingredients in Full
How each is described in the traditional material, what the research says about it, and the safety notes. Where those two accounts disagree, both are given.
Ginger is perhaps the most versatile ingredient in TCM food therapy. Learn about its warming properties, health benefits, and why it appears in so many healing recipes.
In the traditional material
Ginger is pungent and warm in nature. It enters the Lung, Spleen, and Stomach meridians. Fresh ginger (Sheng Jiang) is prized for its ability to release the exterior (induce mild sweating), warm the middle burner (aid digestion), and stop nausea. In TCM, it is the go-to remedy for cold-stomach patterns, morning sickness, and digestive sluggishness.
What the research supports
- Powerful anti-inflammatory compound gingerol supports joint health and reduces exercise-related muscle discomfort
- Well-documented anti-nausea effects — studies confirm ginger is effective for motion sickness, morning sickness, and post-operative nausea
- Supports digestive health by stimulating saliva, bile, and gastric enzyme production
- May help regulate blood sugar and improve insulin sensitivity markers
- Warming properties help improve circulation and reduce cold hands and feet — a common TCM cold-stagnation pattern
How it is used
- Slice fresh ginger and steep in hot water for a simple digestion-supporting tea
- Add generous slices to soups, stews, and bone broths — the longer it simmers, the more warming properties are released
- Grate fresh ginger into stir-fries, marinades, and salad dressings for a pungent kick
- Combine with red dates and goji berries for a balanced, daily wellness tea
Safety
Ginger is very safe in culinary amounts. Medicinal doses (over 4g daily) may cause mild heartburn in sensitive individuals. Ginger may interact with blood-thinning medication — consult your doctor if you take anticoagulants.
When and How to Eat It
Timing
Lunch or dinner, and it suits a hot season or a hot constitution rather than a cold one. Two hours. As a cooling dish it works better served cool or lukewarm than steaming hot, and eating it hot works against the direction it is going.
Who it suits
The dry, thin, hot picture: a dry tickly cough with little coming up, a dry throat, thirst for small sips rather than large amounts, dry skin, and someone who is easily tired and does not have much reserve. It is the cooling, moistening answer for someone who is not well served by the warming soups on this site. Within the framework, the specific indication is a dry lung pattern rather than a phlegmy one.
Who should skip it
This is a cooling, moistening soup and it is the wrong direction for a large number of people. If you run cold, have cold hands and feet, or are easily tired and heavy, it will make the cold worse. If you have a damp-phlegm picture — a wet cough with thick phlegm, a chest that feels full, a greasy tongue coating — this is the wrong soup and the phlegm version is what you want. And the two herbs are real medicines: adenophora is not something to take indefinitely without knowing what you are doing.
How it fits into a day
Lunch or an early dinner, with rice. Served cool rather than hot, which is the detail that matters for a cooling dish. It is a good version for a hot summer week for someone who runs warm, and a poor choice for a cold one. The herbs keep for months dried and the soup reheats well, so it is a practical dish once you have bought the ingredients.
Adjusting the Dish
- Add white fungus for a more strongly moistening version, which is the right addition if the throat is the main problem.
- Add lily bulb, which is the natural third member of this herb group and makes the soup more clearly a lung-and-dryness dish.
- Use chicken instead of duck for a lighter, less rich version. You lose the cooling quality of the duck and gain a soup more people will make twice.
- Add a small amount of goji in the last ten minutes for colour and a little extra yin nourishment.
What This Dish Is Not
It does not treat a cough, a lung condition, or any other medical problem, and a cough that persists beyond three weeks, coughs blood, or comes with breathlessness or weight loss needs a doctor. Adenophora and polygonatum are real medicines rather than vegetables and are not for indefinite self-directed use. The dry-versus-phlegm distinction on this page is a pattern description and not a diagnosis, and a productive cough needs assessment rather than a cooling soup.
Before You Start
Adenophora root needs a soak and the woody ends trimmed. It is a firm, fibrous root — expect to fish it out before serving.
Practical Notes
- Adenophora and codonopsis are often confused because they are related plants. If you cannot find adenophora, codonopsis is a reasonable swap.
- This is a dry-season and autumn dish rather than a summer one.
Substitutions & Swaps
| Instead of | Use | Trade-off |
|---|---|---|
| Adenophora root | Codonopsis, or skip it entirely | Adenophora is not essential. This is a mild, clean broth and it works with duck and ginger alone. |
| Duck | Chicken, or 500g of pork ribs | Chicken is the accessible version. Duck is more traditionally correct for dryness and cough. |

Open Tool →FAQ
Can I use chicken instead of duck?
Duck is preferred for its cooling nature. For a milder version, use lean chicken but the effect will be less cooling.
Where can I buy adenophora root?
Asian grocery stores and Chinese herbal shops carry dried sha shen. It is also available online through TCM herb retailers.
How is this different from the bird's nest chicken soup?
They are the same shape aimed at the same dryness, and the differences are in the degree. This one is cooler and more actively moistening, because the duck is cooling where the chicken is neutral and because the adenophora and polygonatum are more directly yin-nourishing than a neutral protein. The bird's nest version is gentler and much more expensive. If your dryness is mild, either works; if you are genuinely hot, flushed, and thirsty for small sips, this is the more correct one. If you are phlegmy rather than dry, neither is right.
What is the difference between a dry cough and a phlegmy one, practically?
A dry cough produces little or nothing, and the throat feels dry and scratchy; you may wake up coughing because the air is dry. A phlegmy cough produces something, and it is thick, white or clear, and sticky; the chest feels full and you may feel heaviness in the upper body. A yellowish or greenish phlegm is a different matter again and is worth a doctor, because in this framework that is a heat or infection picture rather than a simple one. The distinction matters practically because the two need opposite foods — moistening for the dry version, clearing dampness for the phlegmy one — and using the wrong list makes both worse.
Sources for This Dish
Every claim on this page falls into one of two groups, and they are sourced differently. Statements about the traditional use of an ingredient are references to the classical and modern literature that describes it, and they are not claims that it works. Statements about research point at the published work, including the work that came back negative. Where a search link appears it goes to the current results for that query rather than to a single paper, so you can see the whole record for the ingredient instead of the most favourable part of it.
