Four Treasures Braised Eel for Stomach Nourishment
Four Treasures Braised Eel for Stomach Nourishment
A richly flavored eel dish with four herbal ingredients that soothes stomach cold and supports digestion.
Ingredients
- 500g freshwater eel, cleaned and cut into sections
- 15g Solomon's seal (Yu Zhu)
- 15g Chinese yam (Huai Shan)
- 5g dried tangerine peel (Chen Pi)
- 15g goji berries
- 10g gum plant seed (Qian Zhang Zhi) — optional
- 1 tbsp lard or cooking oil
- 3 slices fresh ginger
- 1 tbsp rice wine
- Salt to taste
How to Prepare
- Rub eel pieces with fresh ginger slices, then pour boiling water over them to remove the slimy coating. Rinse and drain.
- Bring a pot of water to a boil. Add eel, ginger, and lard. Cook for 20 minutes.
- Add Solomon's seal, Chinese yam, tangerine peel, goji berries, and gum plant seed (if using). Reduce heat to low.
- Simmer for 1 hour until the broth is thick and fragrant. Season with salt and a splash of rice wine.
- Serve warm as a nourishing meal.
Why This Works
Eel is traditionally considered a warming food that strengthens the spleen and stomach. The four herbs — Solomon's seal, yam, tangerine peel, and goji — work together to nourish yin, support digestion, and warm the middle burner.
Modern Perspective
Eel is rich in omega-3 fatty acids, vitamin A, and protein. Chinese yam contains prebiotic fibers that support gut health.
Why This Combination
A rich, brown, slow-cooked eel stew, and the four treasures are what make it a tonic rather than a dish. Eel is one of the strongest nourishing foods in the Chinese material — used for deficiency, for the kidneys, for weakness, and in the classical material specifically for someone depleted after illness or overwork. The four treasures are the standard tonic quartet, and the interesting thing is that the version here uses herbs rather than the classical meat-and-organ set, which makes it far more practical. Codonopsis and astragalus for qi, Chinese yam for the spleen, goji for yin, dried tangerine peel to move it. The eel does the heavy nourishing and the aromatics do the work of keeping a rich stew from stagnating.
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.
- Eel
The strongest nourishing food in this dish and one of the classic deficiency foods in the Chinese material. Buy it cleaned and frozen, which is both easier and less expensive.
A gentle qi tonic and the safer of the two qi herbs here when digestion is uncertain. Milder than astragalus and much less likely to cause bloating.
The stronger qi tonic. Together with the codonopsis this is the standard two-herb combination for building qi, and the pair is gentler than either alone.
Supports the spleen and gives the stew body as it breaks down. It is the ingredient that makes this a complete rather than a partial tonic.
Goji for the yin side, added late. The peel moves the qi the herbs build, and without it the whole thing can feel heavy.
To deodorise the eel and add warmth. The rice wine is traditional and does most of the smell work.

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.
Chinese yam (shan yao) is a gentle, nourishing ingredient prized in TCM for supporting digestion and spleen function. Learn about its benefits, uses, and recipes.
In the traditional material
Chinese yam is sweet and neutral in nature, entering the Spleen, Lung, and Kidney meridians. It is one of the most gentle Qi-tonifying foods in TCM, making it suitable for all ages. It strengthens the Spleen (digestive function), nourishes Lung Yin, and consolidates Kidney essence. Unlike stronger herbs, yam can be used daily as a food rather than a medicine.
What the research supports
- Supports healthy digestion — Chinese yam contains digestive enzymes and prebiotic fibers that nourish gut bacteria
- Strengthens the spleen in TCM terms, helping with poor appetite, loose stools, and fatigue after eating
- Supports respiratory health by moistening the lungs, beneficial for dry coughs
- Helps stabilize blood sugar levels due to its low glycemic index and high fiber content
- Nourishes kidney Yin, supporting urinary health and joint lubrication
How it is used
- Peel and slice fresh yam into soups or stews — it absorbs flavors while adding a subtle creamy texture
- Steam and mash as a side dish, similar to mashed potatoes but lighter
- Use dried yam slices (available at Asian groceries) in herbal soups for a more concentrated effect
- Cook into congee (rice porridge) with red dates and goji berries for a nourishing breakfast
Safety
Chinese yam is very safe and can be eaten daily. Fresh yam skin may cause mild itching due to calcium oxalate crystals — use gloves when peeling. Cooking eliminates any irritant compounds. People with diabetes should monitor portions as yam contains natural carbohydrates.
Aged tangerine peel (chen pi) is a cornerstone ingredient in TCM for digestion. Learn about its benefits for bloating, appetite, and phlegm, plus how to use it.
In the traditional material
Dried tangerine peel is pungent, bitter, and warm in nature. It enters the Spleen and Lung meridians. In TCM, it is the premier herb for regulating Qi circulation, especially in the digestive system. Chen pi dries dampness, transforms phlegm, and harmonizes the Stomach. Importantly, the peel must be aged (traditionally 1+ years) — fresh peel is too harsh and lacks the therapeutic depth.
What the research supports
- Relieves bloating, indigestion, and abdominal distension by promoting healthy Qi flow
- Helps reduce phlegm and clears congestion in the chest and respiratory tract
- Stimulates appetite, especially during illness or digestive sluggishness
- Supports healthy gut motility and may reduce nausea
- Contains antioxidant flavonoids (hesperidin, nobiletin) with anti-inflammatory properties
How it is used
- Add 1–2 pieces of aged peel to soups, stews, or braises — it infuses a subtle citrus aroma while aiding digestion of rich foods
- Brew as a digestive tea: steep a small piece in hot water for 5 minutes, optionally with a slice of fresh ginger
- Use in marinades for meat dishes — chen pi pairs especially well with beef and pork
- Incorporate into congee or rice dishes for gentle digestive support
Safety
Chen pi is safe for culinary use. Because it is warm and drying, people with severe Yin deficiency or dry cough should use it sparingly. Fresh tangerine or orange peel should NOT be substituted — only aged chen pi has the proper therapeutic properties. Look for chen pi aged at least 1 year; premium varieties are aged 5–30 years.
Codonopsis root (dang shen) is a mild Qi tonic in TCM, often called "poor man's ginseng." Learn about its benefits, uses, and recipes.
In the traditional material
Codonopsis root is sweet, neutral, and enters the Spleen and Lung meridians. In TCM, it is a classic Qi-tonifying herb that is milder and more affordable than ginseng, making it suitable for long-term daily use. It strengthens the Spleen (digestive function), tonifies the Lungs, and generates body fluids. Unlike ginseng, codonopsis has a very low risk of causing excess heat or irritability.
What the research supports
- Supports energy and stamina — traditionally used for fatigue, weak appetite, and shortness of breath
- Strengthens digestion by tonifying the Spleen, helping with loose stools and poor nutrient absorption
- Supports immune function with polysaccharides that enhance white blood cell activity
- Helps maintain healthy blood sugar levels and supports adrenal function
- Gentle enough for children, elderly, and people recovering from illness
How it is used
- Simmer dried codonopsis slices in soups for 30-60 minutes — commonly paired with astragalus, goji berries, and red dates
- Brew as an energy tea (5g per cup, steep for 10 minutes with a slice of ginger)
- Cook into congee or rice porridge for a gentle daily Qi tonic
- Combine with astragalus for a powerful but gentle Qi-tonifying duo
- Use in slow-cooked herbal soups alongside angelica, white peony, and rehmannia for comprehensive blood and Qi nourishment
Safety
Codonopsis is very safe and well-tolerated. It is suitable for long-term use and rarely causes side effects. People with acute infections or inflammatory conditions should use it cautiously, as it is a tonic. Those with severely weak digestion may experience slight bloating — pair with dried tangerine peel if this occurs. Not recommended for people with uncontrolled high blood pressure.
Astragalus root (Huang Qi) is one of traditional Chinese medicine's most important qi-tonifying herbs. Learn how it supports immunity, energy, and overall vitality.
In the traditional material
Astragalus (Huang Qi) is sweet and slightly warm in nature. It enters the Lung and Spleen meridians. In TCM, it is the primary herb for tonifying Qi (vital energy) and raising the body's defensive energy (Wei Qi). It is often used for fatigue, frequent colds, weakened immunity, and poor appetite. Astragalus is considered a gentle adaptogen suitable for long-term use.
What the research supports
- Supports immune function — studies show astragalus polysaccharides enhance natural killer cell activity and antibody production
- May improve energy and reduce fatigue, particularly in people with chronic exhaustion or recovery from illness
- Supports heart health by improving circulation and reducing oxidative stress markers
- Has adaptogenic properties that help the body respond to physical and environmental stress
How it is used
- Simmer dried astragalus slices in soups and broths — the root is tough and should be removed before serving
- Combine with goji berries, red dates, and ginger for a classic immunity-strengthening tea
- Use in bone broths and long-simmered stews where the root can release its compounds over time
- Avoid eating the fibrous root pieces directly — they are used to infuse liquids, then discarded
Safety
Astragalus is safe for most people in food amounts. Avoid if you have an autoimmune condition or take immunosuppressant medication, as astragalus stimulates the immune system. Not recommended during acute infections with fever.
Goji berries (wolfberries) are one of traditional Chinese medicine's most prized ingredients. Learn about their health benefits, how to use them, and which recipes feature this superfood.
In the traditional material
In traditional Chinese medicine, goji berries are considered sweet and neutral in nature. They primarily nourish the Liver and Kidney meridians, making them a cornerstone ingredient for vitality, vision, and longevity. TCM texts describe goji as a substance that "brightens the eyes, strengthens the lower back, and builds essential essence (Jing)."
What the research supports
- Rich in antioxidants, particularly zeaxanthin, which supports eye health and may reduce age-related vision decline
- Supports immune function — studies show goji polysaccharides can enhance white blood cell activity
- May improve sleep quality and mood when consumed regularly, thanks to their calming effect on the nervous system
- Supports liver health and detoxification pathways, as recognized in both TCM and modern hepatology research
- Helps maintain healthy blood sugar levels and supports energy metabolism
How it is used
- Add a tablespoon to your morning tea or hot water for a gentle energy boost throughout the day
- Simmer in soups and broths — goji berries pair especially well with chicken, ginger, and red dates
- Stir into congee or oatmeal for a nutrient-dense breakfast
- Snack on them raw (dried) as a sweet, chewy treat that beats processed snacks
Safety
Goji berries are safe for most people in food amounts. If you take blood-thinning medication (warfarin), consult your doctor first, as goji may interact. Pregnant women should stick to culinary amounts — medicinal doses are not recommended.
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
Dinner, and this is a once-a-week dish rather than a weekly one — the eel is rich and the combination of two qi herbs is strong. Two hours of simmering, and the flavour is markedly better on the second day. Taken as a tonic it is a course, not a one-off, but a strong one taken less often is better than a strong one taken constantly.
Who it suits
Genuine, long-standing depletion — someone recovering from a serious illness, coming back from a period of overwork, or with the specific picture of fatigue, a poor appetite, and weakness in the limbs that has lasted months. It is a rich, satisfying, whole-meal dish, which is part of why it works for people who cannot manage plain rice.
Who should skip it
This is a strong tonic and the wrong direction for a lot of people. If you are hot, flushed, or sleep badly, two qi herbs plus a rich eel is very likely to make it worse. If you have a thick tongue coating or feel bloated and heavy, the qi tonics need the tangerine peel in generous quantity or the dish is not for you. If you are pregnant, on immunosuppressants, or have an autoimmune condition, both astragalus and a rich eel are questions for a doctor. And eel is a pricey, rich food — this is not a dish to eat twice a week if cost matters.
How it fits into a day
A dinner, once a week, and a rich dish like this is genuinely disruptive within a couple of hours of bed. The reasoning that matters is this: a strong tonic is a course, and the error most people make is taking a strong tonic continuously and then concluding that tonics do not work. Gentler tonics more often, or stronger ones less often, both work better than the usual pattern of trying something once. The eel version is best kept as the once-a-week item and paired with the gentler soups on other nights.
Adjusting the Dish
- Add red dates for more sweetness and qi, and use a little less salt. This is the change that makes it more approachable if you are not used to strong tonics.
- Drop the astragalus and keep only the codonopsis for a much gentler version that still builds. The best single edit if you are new to this.
- Add dried shiitake for depth, and use the soaking liquid in place of some of the water.
- Use chicken instead of eel for a much cheaper version with a similar direction. You lose the classical specificity and gain something most people will cook more often.
What This Dish Is Not
It does not treat anaemia, thyroid disease, or fatigue from an unknown cause, and those are the far more likely explanations for the symptoms people make eel stew for. Astragalus is a genuine medicine with immunological effects, not a vegetable. Eel is rich and oily, so it is not a dish to build a diet around. Unintentional weight loss, breathlessness on minor exertion, or fatigue lasting more than a month need a doctor and a blood test rather than a four-herb stew.
Before You Start
Eel must be cleaned and blanched before the braise. As with the other eel recipes here, this is the difficult part — the braise itself is straightforward.
Practical Notes
- The "four treasures" are a fixed traditional combination and swapping one out changes the formula meaningfully. Use all four or none.
- Eel is traditionally considered one of the strongest kidney foods in the TCM repertoire. It is also an environmental concern — check where yours comes from.
Substitutions & Swaps
| Instead of | Use | Trade-off |
|---|---|---|
| Eel | Any firm white fish, or 500g of beef tendon | Tendon is the closer substitute for the gelatinous quality. Fish makes it a lighter dish. |
| The four herbs | A pre-blended four-herb tonic | Widely available and removes the sourcing problem entirely. |

Open Tool →FAQ
Can I use unagi (pre-cooked eel) from the store?
Fresh eel is best for this slow-braised remedy. Pre-cooked eel is meant for quick grilling and won't produce the same medicinal broth.
What is gum plant seed (Qian Zhang Zhi)?
A traditional herb sometimes added for cough relief. It is optional — the soup works well without it.
Why is eel so highly regarded in Chinese medicine?
It has been used as a deficiency food for a very long time, and the reasoning is nutritional as much as traditional: eel is a fatty, protein-rich fish high in omega-3, and in a dietary tradition that emphasised restoring what had been depleted, a rich animal protein that is easy to digest made obvious sense. What is not defensible is treating it as having a specific medicinal action — it is a genuinely nutritious food, and there is no evidence it does anything a comparable amount of fish or chicken would not. The classical association with the kidneys has no relationship to renal function.
Do I have to use both qi herbs?
No, and using just one is the more sensible approach for most people. The two-herb combination — astragalus with codonopsis — is a standard pairing in the Chinese material, and the codonopsis is there to moderate the astragalus, which is why they are usually given together rather than separately. If you are new to strong tonics, or you bloat easily, or you are not sure how you will react, keep the codonopsis and drop the astragalus. The gentler version builds more slowly and is much better tolerated, and if it causes no problems after a few servings you can add the astragalus back.
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.
