HelloPharmacist Scorecard of Emperor's Teapills 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 13 active ingredients.
  • “Proprietary Extract Blend” is a proprietary blend — the label gives one combined amount (1,360 mg) without saying how much of each component you get.

Emperor's Teapills contains 13 active ingredients presented as a proprietary extract blend plus individual extracts. The main components are Angelica sinensis (Dong Quai) root, Rehmannia root, Oriental Arborvitae seed, Ziziphus jujuba seed, Poria mushroom, Codonopsis root, Figwort root, Ophiopogon tuber, Platycodon root, Salvia miltiorrhiza root, and Schisandra fruit — all traditional Chinese medicine botanicals.

These are combined in a tablet form with inactive ingredients including magnesium silicate, maltose, and china wax.

Does it work?

Not established
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
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use.

Why this rating?
  • The label markets this product for: Sleep support and calming.
  • We looked for evidence on: Insomnia, Stress, Restlessness, Anxiety, Sleep quality.
  • The closest evidence on file: Zizyphus is rated "Insufficient Reliable Evidence To Rate" for Anxiety (Natural Medicines).
  • Also on file: Zizyphus is rated "Insufficient Reliable Evidence To Rate" for Insomnia.
  • Also on file: Poria Mushroom is rated "Insufficient Reliable Evidence To Rate" for Insomnia.

The evidence supporting Emperor's Teapills for any specific condition is not well established in the data we hold. Most of the individual ingredients carry ratings of insufficient reliable evidence for the conditions they've traditionally been used for — anemia, bone health, heart disease, headache, eczema, asthma, kidney disease, diabetes, and fatigue all fall into this category.

Only Rehmannia has one condition (chronic kidney disease) rated as possibly effective. Without clear evidence of benefit, it's hard to say who this product is designed for or whether it works as intended.

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 7 of the 9 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 9 of 9.
  • General safety write-ups exist for 9 of 9.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Dong quai is generally well tolerated, though the most common side effects are burping and flatulence. However, it may increase bleeding risk and cause skin sensitivity to sunlight, so use with caution.

Oriental Arborvitae contains thujone, a compound that at high doses or over long-term use can cause restlessness, vomiting, dizziness, tremors, kidney damage, hallucinations, and convulsions — similar to marijuana intoxication. Codonopsis at very high doses (30–60 grams) may cause chest pain, heart rhythm problems, throat pain, or voice loss; allergic reactions including anaphylaxis have been reported rarely.

Poria mushroom and figwort have limited human safety data. Several ingredients — dong quai, rehmannia, poria, codonopsis, figwort, schisandra, and asparagus root — advise against use during pregnancy; asparagus root alone is rated possibly unsafe.

Most of these ingredients are not recommended while breastfeeding due to insufficient safety data.

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

Why this rating?
  • 8 of the 9 matched ingredients can interact with medications — Zizyphus, Poria Mushroom, Asparagus, Schisandra, Figwort, 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; lithium.
  • For scale: 1,340 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 other blood thinners (anticoagulants or antiplatelet drugs) — dong quai and several other ingredients can increase bleeding risk. Also verify use if you're on antihypertensive drugs (blood pressure), antidiabetes drugs (blood sugar), tacrolimus or other immunosuppressants, sedatives or CNS depressants, diuretics, lithium, or voriconazole.

Schisandra in this product can significantly change how your liver processes many medications and may make some drugs less effective or cause levels of others to climb dangerously.

Schisandra chinensis fruit extract12 drug types · 803 drugs

Cyclophosphamide

Theoretically, schisandra might increase the levels and clinical effects of cyclophosphamide.
In vitro research shows that schisandra increases the concentration of cyclophosphamide, likely through inhibition of cytochrome P450 3A4. After multiple doses of the schisandra constituents schisandrin A and schisantherin A, the maximum concentration of cyclophosphamide was increased by 7% and 75%, respectively, while the overall exposure to cyclophosphamide was increased by 29% and 301%, respectively.

Likelihood Probable Evidence D
Cyclosporine (Neoral, Sandimmune)

Schisandra can increase the levels and clinical effects of cyclosporine.
A small observational study in children with aplastic anemia found that taking schisandra with cyclosporine increased cyclosporine trough levels by 93% without increasing the risk of adverse events. However, the dose of cyclosporine was reduced in 9% of children to maintain appropriate cyclosporine blood concentrations.

Likelihood Probable Evidence B
Cytochrome P450 2C19 (Cyp2C19) Substrates

Theoretically, schisandra might increase the levels and clinical effects of CYP2C19 substrates.
In vitro research shows that schisandra inhibits CYP2C19, and animal research shows that schisandra increases the concentration of voriconazole, a CYP2C19 substrate. Theoretically, schisandra may also inhibit the metabolism of other CYP2C19 substrates. This effect has not been reported in humans.

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

Theoretically, schisandra might decrease the levels and clinical effects of CYP2C9 substrates.
In vitro and animal research suggests that schisandra induces CYP2C9 enzymes. This effect has not been reported in humans.

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

Schisandra can increase the levels and clinical effects of drugs metabolized by CYP3A4.
Most clinical and laboratory research shows that schisandra, administered either as a single dose or up to twice daily for 14 days, inhibits CYP3A4 and increases the concentration of CYP3A4 substrates such as cyclophosphamide, midazolam, tacrolimus, and talinolol. Although one in vitro and animal study shows that schisandra may induce CYP3A4 metabolism, this effect appears to be overpowered by schisandra's CYP3A4 inhibitory activity and has not been reported in humans.

Likelihood Probable Evidence D
Midazolam (Versed)

Schisandra can increase the levels and clinical effects of midazolam.
A small pharmacokinetic study in healthy adults shows that taking schisandra extract (Hezheng Pharmaceutical Co.) containing deoxyschizandrin 33.75 mg twice daily for 8 days and a single dose of midazolam 15 mg on day 8 increases the overall exposure to midazolam by about 119%, increases the peak plasma level of midazolam by 86%, and decreases midazolam clearance by about 52%. This effect has been attributed to inhibition of CYP3A4 by schisandra.

Likelihood Probable Evidence B
P-Glycoprotein Substrates

Schisandra might increase the levels and clinical effects of P-glycoprotein substrates.
In vitro research shows that schisandra extracts and constituents such as schisandrin B inhibit P-glycoprotein mediated efflux in intestinal cells and in P-glycoprotein over-expressing cell lines. Additionally, a small clinical study shows that schisandra increases the peak concentration and overall exposure to talinolol, a P-glycoprotein probe substrate. Theoretically, schisandra might inhibit the efflux of other P-glycoprotein substrates.

Likelihood Possible Evidence D
Sirolimus (Rapamune)

Schisandra can increase the levels and clinical effects of sirolimus.
A small pharmacokinetic study in healthy volunteers shows that taking 3 capsules of schisandra (Hezheng Pharmaceutical Company) containing a total of 33.75 mg deoxyschizandrin twice daily for 13 days and then taking a single dose of sirolimus 2 mg increases the overall exposure and peak level of sirolimus by two-fold. This effect is thought to be due to inhibition of cytochrome P450 3A4 by schisandra, as well as possible inhibition of the P-glycoprotein drug transporter.

Likelihood Probable Evidence B
Tacrolimus (Prograf)

Schisandra can increase the levels and clinical effects of tacrolimus.
Clinical research in healthy children and adults, transplant patients, and patients with nephrotic syndrome and various rheumatic immunologic disorders shows that taking schisandra with tacrolimus increases tacrolimus peak levels by 183% to 268%, prolongs or delays time to peak tacrolimus concentrations, increases overall exposure to tacrolimus by 126% to 343%, and decreases tacrolimus clearance by 19% to 73%. This effect is thought to be due to inhibition of P-glycoprotein drug transporter and CYP3A4 and CYP3A5 by schisandra. Some clinical and observational studies suggest that schisandra increases tacrolimus levels similarly in both expressors and non-expressors of CYP3A5, while other studies suggest it does so to a greater degree in CYP3A5 expressors than non-expressors. Animal research suggests that the greatest increase in tacrolimus levels occurs when schisandra is taken either concomitantly or up to 2 hours before tacrolimus, and clinical and observational research in humans suggests that schisandra may increase whole blood levels of tacrolimus and decrease clearance of tacrolimus in a dose-dependent manner.

Likelihood Probable Evidence B
Talinolol

Schisandra can increase the levels and clinical effects of talinolol.
A small pharmacokinetic study in healthy volunteers shows that taking schisandra extract 300 mg twice daily for 14 days with a single dose of talinolol 100 mg on day 14 increases the peak talinolol level by 51% and the overall exposure to talinolol by 47%. This effect is thought to be due to the possible inhibition of cytochrome P450 3A4 and P-glycoprotein by schisandra. tly.

Likelihood Probable Evidence B
Voriconazole (Vfend)

Theoretically, schisandra might increase the levels and clinical effects of voriconazole.
Animal research shows that oral schisandra given daily for 1 or 14 days increases levels of intravenously administered voriconazole, a cytochrome P450 (CYP) 2C19 substrate. This effect is thought to be due to inhibition of CYP2C19 by schisandra. However, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, schisandra might decrease the levels and clinical effects of warfarin.
Animal research suggests that oral schisandra extract, given daily for 6 days, reduces levels of intravenously administered warfarin. This effect might be due to the induction of cytochrome P450 (CYP) 2C9 metabolism by schisandra. However, this interaction has not been reported in humans.

Ziziphus jujuba seed extract3 drug types · 469 drugs

Antidiabetes Drugs

Theoretically, zizyphus might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Animal research shows that zizyphus has hypoglycemic activity. However, a small clinical study shows that zizyphus fruit powder does not reduce fasting blood glucose levels in patients with type 2 diabetes.

Likelihood Possible Evidence D
Cns Depressants

Theoretically, zizyphus might cause additive sedative effects when taken with CNS depressants.
Some animal research has found that various parts of zizyphus have sedative effects. However, other animal research shows that zizyphus plant extract does not alter sleep parameters when used in combination with pentobarbital.

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

Theoretically, zizyphus might decrease the levels and clinical effects of drugs metabolized by CYP1A2.

Codonopsis pilosula Root Extract3 drug types · 211 drugs

Abiraterone (Zytiga)

Theoretically, taking codonopsis root with abiraterone might reduce the levels and therapeutic effects of abiraterone.
Animal research in rats shows that intragastric administration of codonopsis root along with abiraterone every 2 days for 2 weeks seems to increase the clearance of abiraterone and reduce the overall exposure and time to maximum concentration. This interaction has not been reported in humans.

Likelihood Possible Evidence D
Anticoagulant/Antiplatelet Drugs

Theoretically, codonopsis liquor might increase the risk of bleeding when used with antiplatelet or anticoagulant drugs.
A small clinical study in adults with coronary heart disease shows that consuming Codonopsis pilosula liquor for 4 weeks inhibits platelet aggregation but does not affect tissue-type plasminogen activator (t-PA) or plasminogen activator inhibitor (PAI).

Likelihood Possible Evidence B
Antidiabetes Drugs

Theoretically, codonopsis might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Laboratory and animal research suggest that codonopsis has antidiabetic effects.

Codonopsis pilosula Root Extract full monograph & interactions

Angelica sinensis Root 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

Scrophularia ningpoensis Root Extract2 drug types · 76 drugs

Diuretic Drugs

Theoretically, overuse of figwort might compound diuretic-induced potassium loss. There is some concern that people taking figwort along with potassium depleting diuretics might have an increased risk for hypokalemia. Initiation of potassium supplementation or an increase in potassium supplement dose may be necessary for some patients. Some diuretics that can deplete potassium include chlorothiazide (Diuril), chlorthalidone (Thalitone), furosemide (Lasix), hydrochlorothiazide (HCTZ, Hydrodiuril, Microzide), and others.

Emperor's Teapills by Plum Flower: Common Questions

Does Emperor's Teapills by Plum Flower interact with any medications?
Yes. Based on its ingredients, Emperor's Teapills has a known interaction with 1,339 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?
Emperor's Teapills contains 13 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?
Several ingredients advise against pregnancy use — dong quai, rehmannia, oriental arborvitae, poria, codonopsis, figwort, and schisandra — because there isn't enough safety data or traditional sources suggest they may affect the uterus. Asparagus root is rated possibly unsafe in pregnancy. For breastfeeding, most ingredients lack reliable safety information and are best avoided. Talk to your doctor or pharmacist before use if you're pregnant or nursing.
What are the most common side effects?
Dong quai most commonly causes burping and flatulence. Schisandra can cause decreased appetite, heartburn, stomach upset, or a rash. If you take very high doses of codonopsis (30–60 grams), chest pain or throat pain is possible. Allergic reactions including anaphylaxis have been reported rarely with codonopsis.
Is there any ingredient with no known drug interactions?
Oriental Arborvitae (Platycladus orientalis) has no documented interactions in our data. However, we could not check several ingredients — Polygala tenuifolia, Ziziphus jujuba, Ophiopogon japonicus, Platycodon grandiflorum, and Salvia miltiorrhiza — because we hold no interaction data for them.
Does this product actually work for anything?
The evidence supporting these ingredients for any specific health condition is not established in the data we hold. Most are rated as having insufficient reliable evidence. Only Rehmannia for chronic kidney disease is rated possibly effective — and that's a single condition. You'd want to talk to your doctor about what this product is meant to address in your case.
What is Oriental Arborvitae, and is it safe?
Oriental Arborvitae (Platycladus orientalis) is a plant seed extract. It contains thujone, a compound that can cause serious problems — restlessness, vomiting, dizziness, tremors, kidney damage, hallucinations, and convulsions — if used long-term or at high doses. Human safety data are limited, and it's traditionally avoided in pregnancy and breastfeeding.
What does Dong Quai do in this formula?
Dong Quai (Angelica sinensis) has been used in traditional Chinese medicine for various conditions like anemia, heart disease, and migraine, but the evidence for these uses is insufficient. It has estrogenic effects, so it may theoretically interfere with hormone replacement therapy. It also carries a significant risk of increased bleeding with blood thinners.
