Walk into any Chinese grocery and the herb wall can feel like a math problem with no answer key. How much astragalus goes in a pot of soup? Is a handful of goji berries too many? Do red dates have a limit?
This guide gives you real per-serving amounts for the six herbs you'll actually cook with at home: astragalus (huang qi), goji berries (gou qi zi), dang gui (angelica root), red dates (jujube), codonopsis (dang shen), and dried tangerine peel (chen pi). You'll also see how those everyday kitchen amounts compare to the bigger doses a herbalist uses in a medicinal decoction, how often to eat each one, and who should hold back.
Medical disclaimer: This article is for general education. It describes traditional Chinese food-therapy customs and published research. It is not medical advice and does not replace a licensed doctor or a qualified TCM practitioner. Herbs can interact with medications. If you take a prescription drug, are pregnant or breastfeeding, or have a chronic condition, talk to your doctor before adding herbs to your diet.
Quick Answer: How Much of Each Herb Per Serving?
- Cooking amounts are small. For a soup that serves 4, a normal home cook uses roughly 6-15 g astragalus, a small handful of goji berries (10-15 g), 3-6 g dang gui, 4-8 red dates, 9-15 g codonopsis, and one piece of dried tangerine peel (3-6 g). Divide by the number of bowls to get the per-person amount.
- Medicinal doses are bigger. A herbalist's decoction often uses the upper end of the Chinese Pharmacopoeia range or more (for example, 30 g of astragalus in the classic Dang Gui Bu Xue Tang formula) because it targets a specific pattern for a set number of days, not daily eating.
- Frequency matters more than a single dose. Tonic herbs like astragalus and dang gui are meant for a few times a week or in courses, not unlimited daily use. Gentle food-grade items like goji and red dates can be eaten most days in small amounts.
- Some people should use less or skip it. Anyone on warfarin or other blood thinners, pregnant, running a fever or fighting an acute cold, or with an autoimmune condition should cut amounts sharply or avoid certain herbs and ask a clinician first.
The rest of this guide explains where these numbers come from and how to adjust them.
Why Is There a Difference Between Cooking Amounts and Medicinal Doses?
In Chinese medicine, the same herb plays two roles. In the kitchen it's a food (the tradition calls this 食疗, shí liáo, or food therapy). In a clinic it's a medicine dosed for a pattern.
The official dosing ranges in the 2020 Chinese Pharmacopoeia are written for medicinal decoctions, where a herbalist boils down concentrated amounts to drink as a strong tea over days. Those ranges assume the herb is doing therapeutic work, often alongside several others, for a defined treatment course.
Home cooking is different. You spread the herb across a big pot, simmer it with chicken or pork and other vegetables, and split it among several bowls. Much of the active material stays bound up in the root you don't eat. So the dose per bowl ends up well below a medicinal dose, which is exactly why families can put astragalus and red dates in soup week after week without it being "treatment."
A useful way to think about it: a medicinal decoction is a short, targeted prescription. A pot of herbal soup is closer to seasoning your food with intention. This same logic shows up in our deeper write-up on how to cook Chinese herbal soup, including simmer times and how often to drink it.
Key idea: The Pharmacopoeia numbers below are the total herb in the pot for a family-size dish (serves about 4). They sit at or below the low end of a clinical decoction dose once you divide by the bowls.
How Much Astragalus (Huang Qi) Should I Use in Cooking?
Astragalus is the root you see sliced into pale yellow tongue-shaped pieces. It's the workhorse qi tonic of the Chinese kitchen and the most common herb in a tonic soup.
Cooking amount: Use about 6-15 g for a pot serving 4 (roughly 3-6 dried slices). That's a gentle, food-grade amount that flavors the broth and lends mild sweetness without overwhelming it.
Medicinal range: The standard decoction dose in the Chinese Pharmacopoeia is 9-15 g, and herbalists go up to 30 g or higher for specific patterns. A 2024 review in Chinese Medicine describes astragalus as a "time-honored nourishing herbal medicine" and confirms that both Astragalus membranaceus and Astragalus mongholicus roots are sold as huang qi under the 2020 Pharmacopoeia (Su et al., 2024, PMID 39215362).
For a sense of scale on the medicinal end: the classic two-herb formula Dang Gui Bu Xue Tang, created by Li Dongyuan in 1247, uses 30 g astragalus to 6 g dang gui in a 5:1 ratio, boiled down in water (Mayway Herbs reference). That's a therapeutic dose meant to be sipped, not a soup for the table. We break that formula down in our piece on the 5:1 astragalus and dang gui tonic, Dang Gui Bu Xue Tang.
Safety on the high end: Oral astragalus appears safe for most adults at doses up to 60 g per day for up to four months, but the U.S. National Center for Complementary and Integrative Health (NCCIH) stresses that "a thorough safety evaluation has not been done" (NCCIH, accessed 2026). NCCIH also warns that people with autoimmune diseases should avoid astragalus because it may worsen symptoms, that it can interact with immune-suppressing drugs, and that some animal research suggests it can be toxic to a fetus, so pregnancy is a reason to skip it. For a full profile, see our Huang Qi (astragalus) complete guide.
| Astragalus (Huang Qi) | Amount |
|---|---|
| Cooking, pot serves 4 | 6-15 g (3-6 slices) |
| Per bowl (after splitting) | ~1.5-4 g |
| Pharmacopoeia decoction range | 9-15 g (up to 30 g) |
| Classic tonic formula (DBT) | 30 g per batch |
| Frequency for home cooking | 1-3 times per week |
| Use less / avoid | Pregnancy, autoimmune disease, fever, immunosuppressants |
How Many Goji Berries (Gou Qi Zi) Per Serving?
Goji berries are the soft red berries that turn plump and sweet when simmered. They're the most food-like herb on this list, sweet enough to eat by the spoonful, which is why people overdo them.
Cooking amount: A small handful, about 10-15 g, for a pot serving 4, added in the last 5-10 minutes so they don't dissolve. Per bowl that's roughly 2-4 g, a teaspoon or so.
Daily-eating amount: Goji is gentle enough for most people to use most days. Research gives a helpful anchor: a 2021 randomized pilot trial in Nutrients had healthy adults aged 45-65 eat 28 g of goji berries five times a week for 90 days, and the goji group showed a meaningful rise in macular pigment optical density, a marker tied to eye health (Li et al., 2021, PMID 34959963). So even a generous daily handful sits inside what's been studied. Around 15 g a day is often cited as enough to supply a useful amount of zeaxanthin for the eyes.
The real watch-out is blood thinners. Goji can push up the effect of warfarin. A 2012 case in Pharmacotherapy described a woman whose INR shot to a dangerously high level after she started drinking goji juice while on warfarin (Rivera et al., 2012, PMID 22392461). A 2015 report in Toxicology Reports documented bleeding in a man on warfarin who drank goji-berry wine (Lam et al., 2015, PMID 28962463). If you take warfarin or another anticoagulant, keep goji minimal and tell your doctor. We cover the daily-tea question in depth in can you drink goji and astragalus tea every day.
| Goji Berries (Gou Qi Zi) | Amount |
|---|---|
| Cooking, pot serves 4 | 10-15 g (small handful) |
| Per bowl | ~2-4 g |
| Studied daily intake | 15-28 g/day |
| Frequency | Most days, in food amounts |
| Use less / avoid | On warfarin or other blood thinners |
How Much Dang Gui (Angelica Root) Goes in a Recipe?
Dang gui (Angelica sinensis root) is the strong, almost celery-meets-licorice root used in blood-building soups, especially for women's health and postpartum recovery. It's potent and the flavor is assertive, so a little goes a long way.
Cooking amount: Use 3-6 g for a pot serving 4, usually one or two thin slices. More than that and the soup turns medicinal and slightly bitter.
Medicinal range: The Pharmacopoeia decoction dose is 6-12 g, and a 2014 review in the Journal of Ethnopharmacology documents dang gui's long traditional use as a blood-nourishing herb in Chinese formulas (Hook, 2014, PMID 24365638). In the classic Dang Gui Bu Xue Tang the dose is just 6 g, paired with five times as much astragalus.
Frequency: Dang gui is a true tonic, not an everyday seasoning. Most families use it in occasional courses, a few bowls over a week, and traditionally it's avoided during a cold or when digestion is loose because it's rich and moving. It's also a herb to be careful with if you're on blood thinners (it contains coumarin-type compounds) or pregnant. For ten ways to use it well, see our dang gui (angelica root) recipes.
| Dang Gui (Angelica) | Amount |
|---|---|
| Cooking, pot serves 4 | 3-6 g (1-2 slices) |
| Per bowl | ~1-1.5 g |
| Pharmacopoeia decoction range | 6-12 g |
| Frequency | Occasional courses, not daily |
| Use less / avoid | Pregnancy, blood thinners, fever, loose stools |
How Many Red Dates (Jujube) Should I Add?
Red dates (da zao, Ziziphus jujuba) are the sweet, chewy fruits that soften the harshness of stronger herbs and add natural sweetness. They're the friendliest herb here and the one people worry least about, though more isn't always better.
Cooking amount: 4-8 dates for a pot serving 4. Each dried date is roughly 2-3 g, so that's about 10-20 g total, well inside food range. Pit them if you want a less "hot" soup, since the pits are said to add warmth.
Medicinal range: Traditional decoctions use about 10 g (a few dates) as a one-day dose, and supplemental ranges run 3-12 g daily. A 2020 review in Frontiers in Pharmacology catalogs jujube as an iron- and vitamin-rich food supplement studied for supporting blood (Rashwan et al., 2020, PMID 33324222).
Frequency: Red dates are safe for most days, often 2-4 in a daily tea. Because they're high in natural sugar, people watching blood sugar should keep the count modest. Curious which dates to buy? See our guide to 10 Chinese red date varieties.
| Red Dates (Da Zao) | Amount |
|---|---|
| Cooking, pot serves 4 | 4-8 dates (~10-20 g) |
| Per bowl | 1-2 dates |
| Traditional one-day dose | ~10 g |
| Frequency | Most days, in modest counts |
| Use less / avoid | Diabetes or blood-sugar concerns (high sugar) |
How Much Codonopsis (Dang Shen) Per Pot?
Codonopsis (dang shen) is the long, wrinkled, light-brown root often called "poor man's ginseng" because it's a gentler, food-friendly stand-in for true ginseng. It's a staple in everyday qi-building soups.
Cooking amount: Use 9-15 g for a pot serving 4 (one or two of the long roots, snapped into pieces). It's mild and slightly sweet, so it blends into broth easily.
Medicinal range: The Chinese Pharmacopoeia decoction dose is wide, 9-30 g, because codonopsis is mild and well tolerated even at the high end. That gentleness is why it's the go-to substitute when ginseng would be too stimulating. If you want stronger ginseng options for comparison, see our ginseng soup recipes and the milder American ginseng (xi yang shen) soup.
Frequency: Because it's gentle, codonopsis suits regular use, a few times a week, in fatigue- and digestion-supporting soups. It pairs naturally with astragalus and red dates in qi-building broths described in our overview of top TCM qi-building foods.
| Codonopsis (Dang Shen) | Amount |
|---|---|
| Cooking, pot serves 4 | 9-15 g |
| Per bowl | ~2-4 g |
| Pharmacopoeia decoction range | 9-30 g |
| Frequency | A few times per week |
| Use less / avoid | Acute infection or fever (it's a tonic) |
How Much Dried Tangerine Peel (Chen Pi) Do I Need?
Dried tangerine peel (chen pi) is the aromatic, slightly bitter orange peel that cuts richness, helps digestion, and keeps a heavy soup from feeling greasy. A small piece does a lot.
Cooking amount: One small piece, about 3-6 g, for a pot serving 4. Soak it a few minutes and scrape off the white pith if you want less bitterness.
Medicinal range: The Pharmacopoeia decoction dose is 3-10 g. Chen pi is classified as non-toxic and has a long history as both food and medicine, which is why it shows up in everything from soups to teas to braises. Our deep dive covers its uses in dried tangerine peel (chen pi) in cooking.
Frequency: Safe for regular use, even daily in small amounts, though people with a dry cough or a lot of internal heat are traditionally told to go easy because chen pi is warming and drying.
| Dried Tangerine Peel (Chen Pi) | Amount |
|---|---|
| Cooking, pot serves 4 | 3-6 g (1 small piece) |
| Per bowl | ~1 g |
| Pharmacopoeia decoction range | 3-10 g |
| Frequency | Daily in small amounts is fine |
| Use less / avoid | Dry cough, internal-heat patterns |
A Side-by-Side Dosage Cheat Sheet
Here's every herb in one place. "Cooking" is the total in a pot that serves about 4; "decoction" is the medicinal range a herbalist uses per day.
| Herb (Pinyin) | Cooking amount (serves 4) | Decoction range/day | Cook frequency | First-line caution |
|---|---|---|---|---|
| Astragalus (huang qi) | 6-15 g | 9-15 g (up to 30 g) | 1-3x/week | Pregnancy, autoimmune, fever |
| Goji (gou qi zi) | 10-15 g | 6-15 g | Most days | Warfarin/blood thinners |
| Dang gui (angelica) | 3-6 g | 6-12 g | Occasional courses | Pregnancy, blood thinners |
| Red dates (da zao) | 4-8 dates | ~10 g | Most days | High sugar / diabetes |
| Codonopsis (dang shen) | 9-15 g | 9-30 g | A few times/week | Acute infection/fever |
| Tangerine peel (chen pi) | 3-6 g | 3-10 g | Daily, small amounts | Dry cough, internal heat |
These ranges are a starting point, not a prescription. The classical texts that organized these herbs into "tonify qi," "tonify blood," and "regulate qi" categories, the Shennong Bencao Jing (Han dynasty) and Li Shizhen's Bencao Gangmu (1578), framed dosing as something a skilled practitioner adjusts to the person and the season, not a fixed pill.
How Often Should I Eat These Herbs?
Frequency is the part most home cooks get wrong. They treat a tonic soup like a daily multivitamin. Tradition is more careful.
The split that matters:
- Tonics (astragalus, dang gui, codonopsis): These build and move qi and blood. Use them in courses or a few times a week, not nonstop. In TCM, taking strong tonics when you don't need them, or when you have an "excess" pattern like a fever, can backfire. We spell out the timing in when NOT to eat tonic soups.
- Food-grade items (goji, red dates, tangerine peel): Gentle enough for most days in small amounts. These are closer to seasoning and snacks than to medicine.
A simple home rhythm: Many families cook a tonic soup once or twice a week, especially in cooler months, and keep goji and red dates around for daily teas. That cadence matches the slow-simmered Cantonese tradition without overloading the body. For the seasonal logic behind when to lean on warming tonics, see our seasonal Chinese food-therapy calendar.
Who Should Use Less, or None at All?
Some people need to scale these amounts down or skip certain herbs entirely. This is the most important section for safety.
- On blood thinners (warfarin, etc.): Be very cautious with goji and dang gui. Both have published interaction reports or coumarin content that can raise bleeding risk and INR (Rivera et al., 2012, PMID 22392461; Lam et al., 2015, PMID 28962463). Keep amounts tiny and tell your prescriber.
- Pregnant or breastfeeding: Avoid dang gui (it moves blood) and astragalus (limited safety data; possible fetal toxicity in animals per NCCIH). Goji, red dates, and tangerine peel are generally gentler, but clear any regular herb use with your OB.
- Running a fever or fighting an acute cold: Hold off on tonics. Traditionally you don't pour fuel on an "excess" or "heat" condition, that's a core rule of food therapy.
- Autoimmune disease: Skip astragalus unless a clinician approves, since it may stimulate immune activity (NCCIH).
- Diabetes or blood-sugar concerns: Go easy on red dates (high natural sugar) and watch astragalus, which can affect blood glucose.
- On other prescription drugs: Herbs and drugs can clash. Start with our overview of TCM herb-drug and herb-herb interactions, then ask a pharmacist.
When in doubt, start at the low end of the cooking amounts, eat one bowl, and see how you feel before scaling up.
How Do I Measure Herbs Without a Scale?
You don't always need a kitchen scale, though it helps for the stronger roots. Some rough field conversions for the herbs here:
- Astragalus: one dried slice is roughly 2-3 g, so 3-6 slices lands in the cooking range.
- Goji: a level tablespoon is about 8-10 g; a small cupped handful is 10-15 g.
- Dang gui: one thin slice is about 3 g, which is already a full cooking dose for a pot.
- Red dates: each dried date is 2-3 g, so just count them.
- Codonopsis: one long root snaps into pieces weighing about 9-12 g total.
- Tangerine peel: one palm-sized piece is roughly 3-5 g.
A cheap 5 g-resolution kitchen scale removes the guesswork for under twenty dollars and is worth it once you cook these regularly. Storing the herbs well keeps the doses accurate too (old, dried-out roots lose potency); see how to store Chinese herbs in your pantry.
Frequently Asked Questions
Can I just eyeball the amounts instead of weighing? For gentle items like goji, red dates, and tangerine peel, yes, eyeballing is fine; they're food-grade and forgiving. For the stronger roots, astragalus, dang gui, and codonopsis, weigh them at least until you know what a dose looks like. Dang gui especially is easy to overdo, and too much turns a soup bitter and overly "moving."
Is it bad to put several herbs in one soup? No, that's the norm. A classic tonic soup combines astragalus, codonopsis, goji, and red dates precisely because they balance each other. The combined amounts still stay in food range once spread across a pot and split into bowls. Just keep each individual herb near its cooking amount rather than maxing all of them out at once.
How is a soup dose different from taking a herbal supplement capsule? A capsule or concentrated granule delivers a measured, often higher dose straight to you. A soup spreads a small amount of herb across a big pot of broth and other ingredients, and you eat only one bowl. So a soup dose is almost always milder than a supplement labeled for the same herb. Follow the label on supplements; they aren't interchangeable with cooking amounts.
Do these amounts change for children or older adults? Yes. Children traditionally get smaller amounts (often half the adult cooking dose or less) and milder herbs like red dates and goji rather than strong tonics. Older adults often tolerate gentle tonics like codonopsis well, but anyone on multiple medications should clear herb use with their doctor first because interactions matter more with age. Our tonic soup traditions for elder care covers this in detail.
Why do herbalists use so much more than I do in cooking? Because they're treating a specific pattern for a set course, not feeding a family. A medicinal decoction concentrates a higher dose into a strong tea you drink directly, usually for several days, sometimes with five or more herbs working together. Your soup is preventive and gentle by design. The gap between the two doses is the gap between food and medicine, and it's intentional.
