HelloPharmacist Scorecard of China Tung Hsueh Pills by Plum Flower

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.

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 11 active ingredients.
  • “Proprietary Extract Blend” is a proprietary blend — the label gives one combined amount (1,250 mg) without saying how much of each component you get.

China Tung Hsueh Pills contains 11 ingredients, most of them traditional herbal extracts. The active ingredients include Dong Quai (Angelica sinensis), Frankincense (Boswellia carterii), Myrrh (Commiphora myrrha), Elecampane (Inula helenium), Cassia Cinnamon (Cinnamomum cassia), Rehmannia (Rehmannia glutinosa), Sangre de Grado (Daemonorops draco), and Corydalis yanhusuo.

The product also contains a proprietary extract blend—the exact amounts of each herb aren't listed. Three other ingredients—Salvia miltiorrhiza, Styrax tonkinensis, and Dipsacus asper—round out the formula.

Inactive ingredients include hydrated magnesium silicate, activated carbon, and China wax.

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: HIV/AIDS-related diarrhea — rated "Possibly Effective" (Sangre De Grado) (Natural Medicines).
  • On file: Travelers' diarrhea — rated "Possibly Effective" (Sangre De Grado) (Natural Medicines).
  • On file: Genital herpes — rated "Possibly Effective" (Sangre De Grado) (Natural Medicines).
  • On file: Chronic kidney disease (CKD) — rated "Possibly Effective" (Rehmannia) (Natural Medicines).

The evidence base for most of these ingredients is limited. Rehmannia is possibly effective for chronic kidney disease, and Sangre de Grado is possibly effective for HIV/AIDS-related diarrhea and traveler's diarrhea.

For the other conditions the formula may address—anemia, bone health, heart disease, migraines, eczema, acne, back pain, and others—the data we hold shows insufficient reliable evidence to rate whether these ingredients work. That doesn't mean they don't; it means rigorous clinical trials haven't yet established it.

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 6 of the 8 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 8 of 8.
  • General safety write-ups exist for 8 of 8.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Dong Quai is generally well tolerated but can cause burping and flatulence. Frankincense and Myrrh are generally well tolerated short-term.

Elecampane can trigger allergic skin reactions and stomach upset, especially in people sensitive to ragweed or related plants. Cassia Cinnamon is safe in food amounts but at supplement doses may stress the liver over time due to its coumarin content; rare cases of rash and allergy have been reported.

Corydalis yanhusuo has limited human safety data. Pregnancy and breastfeeding are concerns with several ingredients.

Dong Quai and Myrrh are possibly unsafe or likely unsafe in pregnancy; both may stimulate the uterus. Frankincense, Elecampane, Corydalis yanhusuo, Rehmannia, and Sangre de Grado lack enough safety information—avoid them in pregnancy and while breastfeeding unless your doctor advises otherwise.

Cassia Cinnamon is likely safe in food amounts but avoid medicinal doses in pregnancy. We hold no pregnancy or lactation data for Salvia miltiorrhiza, Styrax tonkinensis, or Dipsacus asper.

Major identified

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

Why this rating?
  • 6 of the 8 matched ingredients can interact with medications — Elecampane, Corydalis Yanhusuo, Myrrh, Dong Quai, Cassia Cinnamon, 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: 1,327 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.

Before taking this product, check with your pharmacist if you take blood thinners or antiplatelet drugs (including warfarin and aspirin)—Dong Quai and Corydalis yanhusuo raise bleeding risk. Also watch for blood sugar medications, blood pressure medications, CNS depressants (sleep aids and sedatives), estrogen-based birth control or hormone therapy, or any drug your liver metabolizes.

Myrrh may make warfarin less effective, and Cassia Cinnamon at high doses may stress the liver alongside other liver-stressing drugs.

Corydalis yanhusuo extract14 drug types · 1,160 drugs

Anticoagulant/Antiplatelet Drugs

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

Likelihood Possible Evidence D
Antidiabetes Drugs

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

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, Corydalis yanhusuo might have additive effects with antihypertensive drugs.
Corydalis yanhusuo 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, Corydalis yanhusuo might also reduce blood pressure.

Likelihood Possible Evidence D
Cns Depressants

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

Likelihood Possible Evidence D
Cyclosporine (Neoral, Sandimmune)

Theoretically, Corydalis yanhusuo might increase blood levels of cyclosporine.
Corydalis yanhusuo 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, Corydalis yanhusuo might also reduce the metabolism of cyclosporine.

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

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

Corydalis yanhusuo contains berberine. In vitro research and preliminary clinical evidence show that berberine can inhibit CYP2D6. Theoretically, Corydalis yanhusuo might also inhibit CYP2D6.

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

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

Likelihood Possible Evidence D
Dextromethorphan (Robitussin Dm, Others)

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

Likelihood Possible Evidence D
Losartan (Cozaar)

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

Likelihood Possible Evidence D
Metformin (Glucophage)

Theoretically, Corydalis yanhusuo might increase the therapeutic and adverse effects of metformin.
Corydalis yanhusuo 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 Corydalis yanhusuo might have this same effect.

Likelihood Possible Evidence D
Midazolam (Versed)

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

Likelihood Possible Evidence D
Pentobarbital (Nembutal)

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

Likelihood Possible Evidence D
Tacrolimus (Prograf)

Theoretically, Corydalis yanhusuo might increase blood levels of tacrolimus.
Corydalis yanhusuo 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 Corydalis yanhusuo might have this same effect.

Likelihood Possible Evidence D

Cinnamomum cassia extract2 drug types · 442 drugs

Antidiabetes Drugs

Theoretically, cassia cinnamon may have additive effects with antidiabetes drugs.
Cassia cinnamon may lower blood glucose levels, and have additive effects in patients treated with antidiabetic agents. Dose adjustments to diabetes medications might be necessary.

Likelihood Possible Evidence B
Hepatotoxic Drugs

Theoretically, large doses of cassia cinnamon might cause additive effects when used with hepatotoxic drugs.
There is some concern that ingesting large amounts of cassia cinnamon for an extended duration might cause hepatotoxicity in some people. Cassia cinnamon contains coumarin, which can cause hepatotoxicity in animal models. In humans, very high doses of coumarin from 50-7000 mg/day can result in hepatotoxicity that resolves when coumarin use is discontinued. Lower amounts might also cause liver problems in sensitive people, such as those with liver disease or those taking potentially hepatotoxic agents.

Rehmannia glutinosa extract2 drug types · 258 drugs

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.
Animal research shows that rehmannia may have hypotensive effects. Laboratory research shows that formulations of dried and processed rehmannia root inhibit angiotensin-converting enzyme (ACE).

Elecampane might have sedative effects.

Likelihood Possible Evidence D
Inula helenium 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.

Likelihood Possible Evidence D
Angelica sinensis extract full monograph & interactions

Commiphora myrrha extract2 drug types · 88 drugs

Antidiabetes Drugs

Theoretically, myrrh might increase the risk of hypoglycemia when taken with antidiabetes drugs.
In vitro and animal research suggests that myrrh has hypoglycemic effects.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, myrrh might decrease the effectiveness of warfarin.
In one case, a patient who was previously stable on warfarin had a significant decline in international normalized ratio (INR) following consumption of an aqueous extract of myrrh.

China Tung Hsueh Pills by Plum Flower: Common Questions

Does China Tung Hsueh Pills by Plum Flower interact with any medications?
Yes. Based on its ingredients, China Tung Hsueh Pills has a known interaction with 1,326 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?
China Tung Hsueh Pills contains 11 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.
Can I take this if I'm pregnant or breastfeeding?
No. Dong Quai and Myrrh are possibly or likely unsafe in pregnancy and may stimulate the uterus. Frankincense, Elecampane, Corydalis yanhusuo, Rehmannia, and Sangre de Grado don't have enough safety data—you shouldn't use them while pregnant or nursing. Talk to your doctor or pharmacist before taking any supplement if you're pregnant, planning pregnancy, or breastfeeding.
What's Dong Quai, and why is it in this formula?
Dong Quai is the root of Angelica sinensis, a traditional Chinese herb. It's used in formulas like this one for blood circulation and women's health. In this product it's paired with other herbs, though the exact amounts aren't labeled.
Does this actually work for what it claims?
The evidence is mixed. Rehmannia is possibly effective for chronic kidney disease, and Sangre de Grado is possibly effective for certain types of diarrhea. For most other uses—anemia, bone health, migraines—the data we hold just isn't strong enough to say either way yet.
What side effects should I watch for?
Most users tolerate it fine. Dong Quai may cause burping and gas. Elecampane can trigger allergic skin reactions or stomach upset, especially if you're sensitive to ragweed or related plants. At high doses, Cassia Cinnamon may stress your liver. If you notice a rash, trouble breathing, or unusual pain, stop and call your pharmacist.
Can I take this with my birth control pills?
Dong Quai has estrogenic effects and theoretically may interfere with estrogen-based contraceptives. Check the checker tool with your specific pill, and ask your pharmacist or doctor to be sure.
Is this safe long-term?
Most of these herbs have limited long-term human safety data. Cassia Cinnamon, if taken at high doses for months, raises concern about liver stress over time. Frankincense and most others are generally used short-term in traditional practice. Talk to your pharmacist about your timeline and health before committing to long-term use.
