HelloPharmacist Scorecard of Yudai Wan by Min Shan

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 7 active ingredients.
  • “Proprietary Extract Blend” is a proprietary blend — the label gives one combined amount (1,320 mg) without saying how much of each component you get.

Yudai Wan contains 7 active ingredients as a proprietary blend and individual extracts. The active ingredients are Angelica sinensis (dong quai), Ligusticum chuanxiong, Phellodendron chinense, Rehmannia glutinosa, Paeonia lactiflora (peony), Ailanthus altissima, and Alpinia officinarum.

These are combined with inactive ingredients including microcrystalline cellulose, hydrated magnesium silicate, dextrin, and China wax, which serve as binders and fillers.

Does it work?

Moderate evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed

This product doesn't appear to be marketed for a specific use, so we graded its ingredients' overall clinical evidence instead.

Moderate

Some clinical evidence supports its ingredients for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredients' overall clinical evidence instead.
  • On file: Chronic kidney disease (CKD) — rated "Possibly Effective" (Rehmannia) (Natural Medicines).

We hold no established effectiveness ratings for Yudai Wan as a whole product. For the individual ingredients, the data we have shows only insufficient evidence for most claimed uses.

Rehmannia glutinosa is rated possibly effective for chronic kidney disease — the strongest evidence rating in this product. All other ingredients lack enough reliable evidence to rate their effectiveness for their traditional uses, which include iron deficiency anemia, osteoporosis, heart disease, migraines, eczema, acne, diabetes, obesity, arthritis, and others.

The evidence, ingredient by ingredient Dong Quai Phellodendron Rehmannia Peony Tree Of Heaven Alpinia

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 5 of the 6 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 6 of 6.
  • General safety write-ups exist for 6 of 6.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Dong quai is generally well tolerated orally, with burping and flatulence most common. It can increase bleeding risk and cause skin sensitivity to sunlight.

Peony is well tolerated for short-term use, with gastrointestinal side effects (abdominal distension, lack of appetite, diarrhea, nausea) most common — diarrhea occurred in 5% of trial participants taking a peony product at high dose. Phellodendron has limited human safety data; one combination product (with magnolia) reported sexual dysfunction, hand shaking, numbness, fatigue, headache, and heartburn in single cases, though it's unclear if phellodendron caused them.

Alpinia may cause gastrointestinal effects — around 5% of trial participants discontinued due to GI side effects. Rehmannia, tree of heaven, and alpinia have limited safety information overall.

Tree of heaven in large amounts may cause queasiness, dizziness, headache, tingling, and diarrhea.

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 6 of the 6 matched ingredients can interact with medications — Peony, Alpinia, Tree Of Heaven, Dong Quai, Phellodendron, among others.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; diabetes medications.
  • For scale: 1,217 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Check your medications if you take warfarin or any blood thinner (anticoagulant or antiplatelet), blood pressure drugs, diabetes medications, hormone-based birth control or hormone replacement therapy, clozapine, phenytoin, metformin, any drug metabolized by cytochrome P450 (CYP1A2, CYP2D6, CYP2C9, or CYP3A4), stomach acid reducers (H2-blockers, antacids, PPIs), or indomethacin. Severity ranges from Major (warfarin) to Minor (stomach drugs and indomethacin).

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence behind its ingredients' uses. Major medication interactions have been identified, and safety information is well characterized.

If you take warfarin or any blood thinner, stop — dong quai in this product raises your bleeding risk significantly. If you take blood pressure drugs, diabetes medications, or drugs cleared by your liver's P450 enzymes, talk to your pharmacist before starting.

This product isn't well studied in humans, and most of its uses lack solid evidence. It's not for you during pregnancy or breastfeeding.

Phellodendron chinense extract14 drug types · 1,160 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, phellodendron might increase the risk of bleeding when used with anticoagulant or antiplatelet drugs.
Phellodendron contains berberine. In vitro and in vivo research suggest that berberine can inhibit platelet aggregation. Theoretically, phellodendron might also inhibit platelet aggregation.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, phellodendron may increase the risk of hypoglycemia when taken with antidiabetes drugs.
Phellodendron contains berberine. Clinical research shows that berberine may lower blood glucose levels. Theoretically, phellodendron might also lower blood glucose levels.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, phellodendron might have additive effects with antihypertensive drugs.
Phellodendron contains berberine. Animal research suggests that berberine can have hypotensive effects. Also, a clinical study suggests that taking berberine in combination with amlodipine can lower systolic and diastolic blood pressure when compared with amlodipine alone. Theoretically, phellodendron might also reduce blood pressure.

Likelihood Possible Evidence D
Cns Depressants

Theoretically, phellodendron might increase the sedative effects of CNS depressants.
Phellodendron contains berberine. Animal research suggests that berberine may have sedative effects. Theoretically, phellodendron might also have CNS depressants effects.

Likelihood Possible Evidence D
Cyclosporine (Neoral, Sandimmune)

Theoretically, phellodendron might increase blood levels of cyclosporine.
Phellodendron contains berberine. Preliminary clinical research shows that berberine can reduce metabolism of cyclosporine and increase serum levels, likely through inhibition of cytochrome P450 3A4 (CYP3A4), which metabolizes cyclosporine. Theoretically, phellodendron might also reduce the metabolism of cyclosporine.

Likelihood Possible Evidence D
Cytochrome P450 2C9 (Cyp2C9) Substrates

Theoretically, phellodendron might increase serum levels of drugs metabolized by CYP2C9.
Phellodendron contains berberine. Preliminary clinical research shows that berberine can inhibit CYP2C9. Theoretically, phellodendron might also inhibit CYP2C9.

Likelihood Possible Evidence D
Cytochrome P450 2D6 (Cyp2D6) Substrates

Theoretically, phellodendron might increase serum levels of drugs metabolized by CYP2D6.
Phellodendron contains berberine. In vitro research and preliminary clinical evidence show that berberine can inhibit CYP2D6. Theoretically, phellodendron might also inhibit CYP2D6.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, phellodendron might increase serum levels of drugs metabolized by CYP3A4.
Phellodendron contains berberine. In vitro research and preliminary clinical research show that berberine moderately inhibits CYP3A4. Theoretically, phellodendron might also inhibit CYP3A4.

Likelihood Possible Evidence D
Dextromethorphan (Robitussin Dm, Others)

Theoretically, phellodendron may increase serum levels of dextromethorphan.
Phellodendron contains berberine. Preliminary clinical research shows that berberine can inhibit cytochrome P450 2D6 (CYP2D6) activity and reduce the metabolism of dextromethorphan. Theoretically, phellodendron may also inhibit the metabolism of dextromethorphan.

Likelihood Possible Evidence D
Losartan (Cozaar)

Theoretically, phellodendron might reduce the therapeutic effects of losartan by decreasing its conversion to its active form.
Phellodendron contains berberine. Preliminary clinical research suggests that berberine can inhibit cytochrome P450 2C9 (CYP2C9) activity and reduce metabolism of losartan. Theoretically, phellodendron might also inhibit the metabolism of losartan.

Likelihood Possible Evidence D
Metformin (Glucophage)

Theoretically, phellodendron might increase the therapeutic and adverse effects of metformin.
Phellodendron contains berberine. In vitro and animal studies show that berberine can increase the systemic exposure and half-life of metformin, potentially increasing metformin's effects and side effects. This interaction seems to be most apparent when berberine is administered 2 hours prior to metformin. Taking berberine and metformin at the same time does not appear to increase systemic exposure to metformin. It is unclear if phellodendron might have this same effect.

Likelihood Possible Evidence D
Midazolam (Versed)

Theoretically, phellodendron might reduce metabolism of midazolam, which might increase the risk of severe adverse effects.
Phellodendron contains berberine. Preliminary clinical research shows that berberine can inhibit cytochrome P450 3A4 (CYP3A4) activity and reduce metabolism of midazolam. Theoretically, phellodendron might also inhibit the metabolism of midazolam.

Likelihood Possible Evidence D
Pentobarbital (Nembutal)

Theoretically, phellodendron might increase the sedative effect of pentobarbital.
Phellodendron contains berberine. Animal research shows that berberine can prolong pentobarbital-induced sleeping time. Theoretically, phellodendron might increase the sedative effects of pentobarbital.

Likelihood Possible Evidence D
Tacrolimus (Prograf)

Theoretically, phellodendron might increase blood levels of tacrolimus.
Phellodendron contains berberine. In a 16-year-old patient with idiopathic nephrotic syndrome who was being treated with tacrolimus 6.5 mg twice daily, intake of berberine 200 mg three times daily increased the blood concentration of tacrolimus from 8 to 22 ng/mL. Following a reduction of the tacrolimus dose to 3 mg daily, blood levels of tacrolimus decreased to 12 ng/mL. It is unclear if phellodendron might have this same effect.

Paeonia lactiflora extract7 drug types · 811 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, combining peony with anticoagulant or antiplatelet drugs might increase the risk of bleeding.
In vitro research suggests that peony might have antiplatelet, anticoagulant, and antithrombotic effects.

Likelihood Possible Evidence D
Clozapine (Clozaril)

Theoretically, peony might increase the levels and clinical effects of clozapine.
In vitro research shows that peony suppresses the metabolism of clozapine via weak-to-moderate inhibitory effects on cytochromes P450 (CYP) 1A2 and CYP3A4. This effect has not been reported in humans.

Likelihood Possible Evidence D
Contraceptive Drugs

Theoretically, peony might interfere with contraceptive drugs due to competition for estrogen receptors.
In vitro and animal research shows that peony extract has estrogenic activity. Concomitant use might also increase the risk for estrogen-related adverse effects.

Likelihood Possible Evidence D
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, use of peony may increase the levels and clinical effects of drugs metabolized by CYP1A2.
In vitro research shows that peony suppresses the metabolism of clozapine via weak-to-moderate inhibitory effects on CYP1A2 and CYP3A4. This effect has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, use of peony may increase the levels and clinical effects of drugs metabolized by CYP3A4.
In vitro research shows that peony suppresses the metabolism of clozapine via weak-to-moderate inhibitory effects on CYP1A2 and CYP3A4. This effect has not been reported in humans.

Likelihood Possible Evidence D
Estrogens

Theoretically, concomitant use of large amounts of peony might interfere with hormone replacement therapy and/or increase the risk for estrogen-related adverse effects.
In vitro and animal research shows that peony extract has estrogenic activity. Theoretically, peony might compete for estrogen receptors and/or cause additive estrogenic effects.

Likelihood Possible Evidence D
Phenytoin (Dilantin)

Theoretically, peony might reduce the levels and clinical effects of phenytoin.
Animal research shows that taking peony root reduces levels of phenytoin. Some researchers suggest that peony root might affect cytochrome P450 (CYP) 2C9, which metabolizes phenytoin. However, preliminary research in humans shows that peony root does not alter levels of losartan (Cozaar), which is also metabolized by CYP2C9.

Antidiabetes Drugs

Theoretically, rehmannia might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Animal research shows that rehmannia may have hypoglycemic effects.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, rehmannia might increase the risk of hypotension when taken with antihypertensive drugs.

Likelihood Possible Evidence D
Rehmannia glutinosa extract full monograph & interactions

Angelica sinensis extract3 drug types · 163 drugs

Warfarin (Coumadin)

Dong quai may increase the risk of bleeding when used with warfarin.
Case reports suggest that concomitant use of dong quai with warfarin can increase the anticoagulant effects of warfarin and increase the risk of bleeding. In one case, after 4 weeks of taking dong quai 565 mg once or twice daily, the international normalized ratio (INR) increased to 4.9. The INR normalized 4 weeks after discontinuation of dong quai.

Likelihood Probable Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, dong quai may increase the risk of bleeding when used with anticoagulant or antiplatelet drugs; however, research is conflicting.
Animal studies suggest that dong quai has antithrombin activity and inhibits platelet aggregation due to its coumarin components. Additionally, some case reports in humans suggest that dong quai can increase the anticoagulant effects of warfarin. However, clinical research in healthy adults shows that taking 1 gram of dong quai root daily for 3 weeks does not significantly inhibit platelet aggregation or cause bleeding. Until more is known, use dong quai with caution in patients taking antiplatelet/anticoagulant drugs.

Likelihood Possible Evidence D
Estrogens

Theoretically, dong quai may reduce the effects of estrogens.
Dong quai has estrogenic effects. Theoretically, concomitant use of large amounts of dong quai might interfere with hormone replacement therapy due to competition for estrogen receptors.

Yudai Wan by Min Shan: Common Questions

Does Yudai Wan by Min Shan interact with any medications?
Yes. Based on its ingredients, Yudai Wan has a known interaction with 1,216 medications, including 2 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Yudai Wan contains 7 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
What is dong quai, and why is it in this product?
Dong quai is Angelica sinensis, a root used in traditional Chinese medicine. It's included here as part of the herbal blend, though we don't have established evidence that it works for any specific condition.
Can I take this while on birth control?
Peony in this product has estrogenic activity and may theoretically interfere with hormonal contraceptives. Talk to your pharmacist or doctor before combining them.
Is this safe during pregnancy or breastfeeding?
No. Dong quai may stimulate the uterus and affect bleeding, and phellodendron contains berberine, which may not be safe in pregnancy. Dong quai is not safe while breastfeeding. The safety data for the other ingredients during pregnancy and lactation aren't complete enough — avoid this product and speak with your doctor or pharmacist.
What are the most common side effects?
Dong quai most commonly causes burping and flatulence. Peony may cause abdominal distension, loss of appetite, diarrhea, and nausea. Alpinia may cause gastrointestinal effects. Tree of heaven in large amounts may cause queasiness, dizziness, headache, tingling, and diarrhea.
Does this product have any fillers?
Yes. Inactive ingredients include microcrystalline cellulose, hydrated magnesium silicate, dextrin, and China wax, which are used as binders and fillers.
Why can't you check one of the ingredients?
We have no interaction data on file for Ligusticum chuanxiong. That doesn't mean it's safe — just that we haven't checked it yet. Your pharmacist can help assess any additional risk.
