HelloPharmacist Scorecard of Subdue Dampness 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 9 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.

Subdue Dampness Teapills contains 9 ingredients total, including extracts of peony, poria mushroom, Job's tears, phellodendron bark, alisma root, gardenia fruit, dictamnus root bark, dioscorea tuber, and tetrapanax pith. The product is formulated as a proprietary blend, so the exact amount of each active ingredient isn't broken out on the label.

The tablet also contains inactive ingredients — dextrin, hydrated magnesium silicate, activated charcoal, and china wax — which serve as binders and fillers to hold the formula together.

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: Herbal supplement for traditional dampness clearing.
  • We looked for evidence on: Diarrhea, Anxiety, Stress, Insomnia, Edema, Digestive support — and 1 related terms.
  • The closest evidence on file: Poria Mushroom is rated "Insufficient Reliable Evidence To Rate" for Diarrhea (Natural Medicines).
  • Also on file: Poria Mushroom is rated "Insufficient Reliable Evidence To Rate" for Insomnia.
  • Also on file: Phellodendron is rated "Insufficient Reliable Evidence To Rate" for Stress.

The evidence for Subdue Dampness Teapills is limited. For peony, the data shows insufficient reliable evidence to rate its effectiveness for aging skin, anal fissures, atherosclerosis, chronic fatigue syndrome, cirrhosis, and migraine headache.

Poria mushroom similarly lacks established evidence for cancer, chronic fatigue, dementia, diabetes, diabetic kidney disease, and diarrhea. Job's tears shows insufficient evidence for cholesterol management.

Phellodendron is rated insufficient for acne, prostate health, diabetes, weight management, joint pain, and ulcers. Gardenia also carries insufficient ratings for anxiety, dementia, depression, diabetes, high blood pressure, and flu.

The evidence we hold doesn't establish that this product works for any condition.

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 4 of the 5 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 5 of 5.
  • General safety write-ups exist for 5 of 5.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Peony is generally well tolerated for short-term use, though high-quality safety data are limited. The most common side effects are stomach upset — abdominal bloating, loss of appetite, diarrhea, and nausea — with diarrhea reported in a small number of trial participants.

There's one case report of bleeding problems in someone taking a different peony-containing product alongside warfarin. Poria mushroom is generally well tolerated but has limited human safety data; allergic reactions have been reported rarely.

Phellodendron has minimal safety data and is used short-term in traditional medicine. A combination product with phellodendron and magnolia reported isolated cases of sexual dysfunction, hand shaking, numbness, fatigue, headache, and heartburn in clinical trials, though a causal link wasn't established.

Job's tears is generally safe as a cooked food, but concentrated supplement evidence is sparse. Gardenia has limited safety information; topical exposure can cause allergic skin reactions in sensitive people, and there is one case report of blue-gray skin discoloration with long-term use of a multi-ingredient product containing gardenia.

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 5 of the 5 matched ingredients can interact with medications — Peony, Poria Mushroom, Phellodendron, Job's Tears, Gardenia.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; immunosuppressants / transplant drugs; diabetes medications.
  • For scale: 1,319 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 with your pharmacist before taking this product if you're on blood thinners or antiplatelet drugs (like warfarin or aspirin), birth control pills or hormone therapy, seizure medications (especially phenytoin), blood pressure medications, antidiabetes drugs, sedatives or sleep aids, or any drug your liver metabolizes through the CYP1A2, CYP2D6, CYP2C9, or CYP3A4 pathways. These are common enzymes, so most prescription medications go through at least one.

Additionally, if you take theophylline, dextromethorphan, chlorzoxazone, or diltiazem, this product may increase their absorption.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

Subdue Dampness Teapills is a traditional formula whose effectiveness hasn't been established in the data we hold. If you take any blood thinners, birth control, seizure medications, blood pressure drugs, diabetes medications, or sedatives, talk to your pharmacist before trying this product — the interactions are real enough to warrant a conversation.

The same goes for any other prescription drugs you're on. Generally well tolerated, but pregnancy and breastfeeding are not recommended due to limited safety data.

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 suffruticosa 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.

Coix lachryma jobi extract5 drug types · 128 drugs

Antidiabetes Drugs

Preliminary evidence shows that constituents of Job's tears might have hypoglycemic effects. Theoretically, concomitant use with drugs that decrease blood glucose levels might increase the risk of hypoglycemia. Some antidiabetes drugs include glimepiride (Amaryl), glyburide (DiaBeta, Glynase PresTab, Micronase), insulin, pioglitazone (Actos), rosiglitazone (Avandia), chlorpropamide (Diabinese), glipizide (Glucotrol), tolbutamide (Orinase), and others.

Likelihood Possible Evidence D
Chlorzoxazone (Parafon Forte, Paraflex)

Animal research suggests that Job's tears might enhance absorption of chlorzoxazone in the small intestine. Single dose and short-term oral administration of Job's tears bran ethanolic extract along with oral administration of a five-drug cocktail containing chlorzoxazone increases chlorzoxazone peak plasma concentration and area under the plasma concentration-time curve (AUC) without altering major cytochrome P450 activities in the liver. This effect has not been reported in humans.

Likelihood Possible Evidence D
Dextromethorphan (Robitussin Dm, Others)

Animal research suggests that Job's tears might enhance absorption of dextromethorphan in the small intestine.

Subdue Dampness Teapills by Plum Flower: Common Questions

Does Subdue Dampness Teapills by Plum Flower interact with any medications?
Yes. Based on its ingredients, Subdue Dampness Teapills has a known interaction with 1,318 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Subdue Dampness Teapills contains 9 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 while I'm pregnant or breastfeeding?
No. The safety data advises against use during pregnancy. There's also not enough reliable information to consider it safe while breastfeeding, so both are best avoided. Talk to your doctor or pharmacist if you're pregnant or nursing and want to discuss options.
What are the most common side effects?
Stomach upset is the main concern — bloating, loss of appetite, diarrhea, and nausea. These are generally mild and reported in small numbers of people who used peony-containing products. If you develop unusual bleeding or bruising, stop and contact your pharmacist right away.
Does this product actually work for dampness or the conditions it claims?
The evidence we hold doesn't establish that it works for any specific condition. All the ingredients carry ratings of insufficient evidence, meaning we simply don't have reliable data showing they're effective.
What is Job's tears, and why is it in here?
Job's tears is a grain-like plant used in traditional Asian medicine. It's included in this formula as part of the traditional blend, though we don't have strong evidence for what it does on its own or in this combination.
Will this interfere with my birth control?
Possibly, yes. Peony in this product has estrogenic activity and theoretically could interfere with hormonal contraceptives. Talk to your pharmacist or doctor before starting this product if you're on the pill or a hormonal method.
How long is it safe to take this?
The safety data are limited. Several ingredients are noted as generally well tolerated for short-term use in traditional medicine, but long-term safety hasn't been well studied. Check with your pharmacist about how long you should take it.
