HelloPharmacist Scorecard of Pinellia & Magnolia 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 5 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.

This product contains five active herbal extracts in a proprietary blend: Magnolia officinalis bark, Poria cocos mushroom, Pinellia ternata rhizome, ginger (Zingiber officinale), and Perilla frutescens leaf. The inactive ingredients are maltose, microcrystalline cellulose, magnesium silicate, activated charcoal, and china wax — standard tablet 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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: Traditional herbal digestive and respiratory support.
  • We looked for evidence on: Nausea and vomiting, Cough, Dyspepsia, Asthma, Atopic dermatitis (eczema), Allergic rhinitis (hay fever) — and 4 related terms.
  • The strongest evidence on file: Ginger is rated "Possibly Effective" for Pregnancy-induced nausea and vomiting (Natural Medicines).
  • Also on file: Ginger is rated "Possibly Ineffective" for Chemotherapy-induced nausea and vomiting (CINV).
  • Also on file: Magnolia is rated "Insufficient Reliable Evidence To Rate" for Allergic rhinitis (hay fever), Anxiety, Stress.

The evidence for what this product does is mixed and largely incomplete. Ginger has possibly effective evidence for pregnancy-related nausea, period pain, and osteoarthritis.

Magnolia bark has possibly effective evidence for gingivitis (gum disease), but the other conditions studied — allergic rhinitis, anxiety, and dental plaque — lack reliable evidence. For the other three ingredients, the effectiveness research we hold either shows insufficient evidence or hasn't been established in our data.

The evidence, ingredient by ingredient Magnolia Poria Mushroom Pinellia Ternata Ginger Perilla

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 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.

Magnolia bark is generally well tolerated orally, though human safety data are limited. The safety notes advise against use in pregnancy and breastfeeding because there isn't enough information.

Poria mushroom is well tolerated in traditional use, but pregnancy and breastfeeding data are inadequate — avoidance is recommended. Pinellia ternata carries a caution: raw material is toxic and irritating, so only properly processed preparations should be used.

It also contains ephedrine alkaloids, which may cause high blood pressure, rapid heartbeat, heart attack, stroke, or seizures. Avoid in pregnancy and breastfeeding.

Ginger is generally well tolerated at typical food and supplement doses, though higher doses (over 5 grams per day) increase side effects like heartburn, diarrhea, and stomach upset. Perilla is well tolerated as a food, but rare anaphylaxis has been reported with perilla seeds.

Pregnancy and breastfeeding data are insufficient.

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?
  • 4 of the 5 matched ingredients can interact with medications — Magnolia, Poria Mushroom, Ginger, Pinellia Ternata.
  • 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: 1,211 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 before taking this if you use benzodiazepines or other sedatives (Pinellia may make them stronger), blood thinners like warfarin (Magnolia and ginger may raise bleeding risk), diabetes medications (ginger may lower blood sugar more), blood pressure drugs like losartan or nifedipine (ginger may enhance effects), anticholinergic or cholinergic drugs (Poria may interfere), or certain cancer medications (ginger may alter how your body processes them). All of these interactions are rated Moderate.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This is a traditional herbal blend used for respiratory and digestive support, but the evidence for what it actually does is sparse. If you take sedatives, blood thinners, diabetes drugs, or blood pressure medication, you need to check with your pharmacist before starting it — the interactions are real enough to matter.

If you're pregnant or nursing, talk with your doctor first; safety data are too thin to move ahead on your own.

For each ingredient in Pinellia & Magnolia Teapills with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.

Zingiber officinale Rhizome Extract14 drug types · 1,007 drugs

Anticoagulant/Antiplatelet Drugs

Ginger may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs. However, research is conflicting.
Laboratory research suggests that ginger inhibits thromboxane synthetase and decreases platelet aggregation. However, this has not been demonstrated unequivocally in humans, with mixed results from clinical trials. Theoretically, excessive amounts of ginger might increase the risk of bleeding when used with anticoagulant/antiplatelet drugs.

Likelihood Possible Evidence B
Antidiabetes Drugs

Theoretically, taking ginger with antidiabetes drugs might increase the risk of hypoglycemia.
Animal and human research suggests that ginger might increase insulin levels and/or decrease blood glucose levels.

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

Ginger might increase or decrease the levels of CYP3A4 substrates.
In vitro research and some case reports suggest that ginger inhibits CYP3A4 activity. Three case reports from the World Health Organization (WHO) adverse drug reaction database describe increased toxicity in patients taking ginger and cancer medications that are CYP3A4 substrates (imatinib, dabrafenib, and crizotinib). However, the causality of this interaction is unclear due to the presence of multiple interacting drugs and routes of administration.
Conversely, other in vitro research suggests that ginger induces CYP3A4 activity, leading to reduced levels of CYP3A4 substrates. However, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Losartan (Cozaar)

Theoretically, ginger might increase levels of losartan and the risk of hypotension.
In animal research, ginger increased the levels and hypotensive effects of a single dose of losartan. It is not clear if ginger alters the concentration or effects of losartan when taken continuously. Additionally, this interaction has not been shown in humans.

Likelihood Possible Evidence D
Nifedipine (Procardia)

Ginger may have antiplatelet effects and increase the risk of bleeding if used with nifedipine.
Clinical research shows that combined treatment with ginger 1 gram plus nifedipine 10 mg significantly inhibits platelet aggregation when compared to nifedipine or ginger alone.

Likelihood Possible Evidence B
P-Glycoprotein Substrates

Ginger might increase the absorption and blood levels of P-glycoprotein (P-gp) substrates.
In vitro research and case reports suggest that ginger inhibits drug efflux by P-gp, potentially increasing absorption and serum levels of P-gp substrates. Two case reports from the World Health Organization (WHO) adverse drug reaction database describe increased toxicity in patients taking ginger and cancer medications that are P-gp substrates (trametinib, crizotinib). However, the causality of this interaction is unclear due to the presence of multiple interacting drugs and routes of administration.

Likelihood Possible Evidence D
Phenprocoumon (Marcoumar, Others)

Ginger might increase the risk of bleeding with phenprocoumon.
Phenprocoumon, a warfarin-related anticoagulant, might increase the international normalized ratio (INR) when taken with ginger. There is one case report of a 76-year-old woman with a stable INR on phenprocoumon that increased to greater than 10 when she began consuming dried ginger and ginger tea.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Ginger might increase the risk of bleeding with warfarin.
Laboratory research suggests that ginger might inhibit thromboxane synthetase and decrease platelet aggregation. In one case report, ginger increased the INR when taken with phenprocoumon, which has similar pharmacological effects as warfarin. In another case report, ginger increased the INR when taken with a combination of warfarin, hydrochlorothiazide, and acetaminophen. A longitudinal analysis suggests that taking ginger increases the risk of bleeding in patients taking warfarin for at least 4 months. However, research in healthy people suggests that ginger has no effect on INR, or the pharmacokinetics or pharmacodynamics of warfarin. Until more is known, monitor INRs closely in patients taking large amounts of ginger.

Likelihood Possible Evidence B
Calcium Channel Blockers

Theoretically, taking ginger with calcium channel blockers might increase the risk of hypotension.
Some animal and in vitro research suggests that ginger has hypotensive and calcium channel-blocking effects. Another animal study shows that concomitant administration of ginger and the calcium channel blocker amlodipine leads to greater reductions in blood pressure when compared with amlodipine alone.

Likelihood Unlikely Evidence D
Cyclosporine (Neoral, Sandimmune)

Theoretically, when taken prior to cyclosporine, ginger might decrease cyclosporine levels.
In an animal model, ginger juice taken 2 hours prior to cyclosporine administration reduced the maximum concentration and area under the curve of cyclosporine by 51% and 40%, respectively. This effect was not observed when ginger juice and cyclosporine were administered at the same time.

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

Theoretically, ginger might increase the levels of CYP1A2 substrates.
In vitro research shows that ginger inhibits CYP1A2 activity. However, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2B6 (Cyp2B6) Substrates

Theoretically, ginger might increase the levels of CYP2B6 substrates.
In vitro research shows that ginger inhibits CYP2B6 activity. However, this interaction has not been reported in humans.

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

Theoretically, ginger might increase the levels of CYP2C9 substrates.
In vitro research shows that ginger inhibits CYP2C9 activity. However, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Metronidazole (Flagyl)

Theoretically, ginger might increase levels of metronidazole.
In an animal model, ginger increased the absorption and plasma half-life of metronidazole. In addition, the elimination rate and clearance of metronidazole was significantly reduced.

Likelihood Possible Evidence D
Zingiber officinale Rhizome Extract full monograph & interactions

Poria cocos Sclerotium Extract3 drug types · 417 drugs

Anticholinergic Drugs

Theoretically, poria mushroom might decrease the clinical effects of anticholinergic drugs.
In animal research, poria mushroom essential oil reduces acetylcholinesterase activity. This interaction has not been shown in humans.

Likelihood Possible Evidence D
Cholinergic Drugs

Theoretically, poria mushroom might have additive effects when used with cholinergic drugs.
In animal research, poria mushroom essential oil reduces acetylcholinesterase activity. This interaction has not been shown in humans.

Likelihood Possible Evidence D
Cns Depressants

Theoretically, taking poria mushroom extract may enhance the therapeutic and adverse effects of sedatives.
Animal research shows that poria mushroom extract has sedative properties. This interaction has not been shown in humans.

Likelihood Possible Evidence D
Poria cocos Sclerotium Extract full monograph & interactions

Magnolia officinalis Bark Extract2 drug types · 351 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, magnolia might have additive effects and increase the risk of bleeding when used with anticoagulant or antiplatelet drugs.
In vitro research shows that the chemicals magnolol and honokiol, isolated from magnolia bark, inhibit platelet aggregation that is experimentally induced by collagen and arachidonic acid. However, they do not inhibit platelet aggregation that is induced by adenosine diphosphate, platelet-activating factor, or thrombin. This interaction has not been reported in humans.

Likelihood Possible Evidence D
Cns Depressants

Theoretically, concomitant use of large doses of magnolia bark and CNS depressants might have additive effects.
In vitro and animal research shows that constituents extracted from magnolia bark, especially honokiol and magnolol, have sedative effects. These effects may be due to the inhibition of catecholamine release and modulation of gamma-aminobutyric acid-A (GABA-A) receptors.

Likelihood Possible Evidence D

Barbiturates

Evidence from animal research shows that a Pinellia ternata preparation decreases activity and increases sleeping time. Theoretically, Pinellia ternata can potentiate the therapeutic effect of barbiturates. Some of these sedative medications include pentobarbital (Nembutal), phenobarbital (Luminal), secobarbital (Seconal), and others.

Likelihood Possible Evidence D
Benzodiazepines

Evidence from animal research shows that a Pinellia ternata preparation decreases activity and increases sleeping time. Theoretically, Pinellia ternata can potentiate the therapeutic effect of benzodiazepines. Some benzodiazepines include lorazepam (Ativan), alprazolam (Xanax), diazepam (Valium), midazolam (Versed), and others.

Likelihood Possible Evidence D
Cns Depressants

Evidence from animal research shows that a Pinellia ternata preparation decreases activity and increases sleeping time. Theoretically, Pinellia ternata can potentiate the therapeutic effect of CNS depressants. Some of these medications include antihistamines, barbiturates, benzodiazepines, tricyclic antidepressants, and others.

Pinellia & Magnolia Teapills by Plum Flower: Common Questions

Does Pinellia & Magnolia Teapills by Plum Flower interact with any medications?
Yes. Based on its ingredients, Pinellia & Magnolia Teapills has a known interaction with 1,210 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Pinellia & Magnolia Teapills contains 5 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 Pinellia ternata and why is it in this product?
Pinellia ternata is a rhizome (underground stem) extract used in traditional herbal medicine. This product contains it as a processed extract. Raw Pinellia is toxic, so it's important that supplement-grade material is properly prepared — which this should be — and used as directed.
Does ginger in this product help nausea?
Ginger has possibly effective evidence for pregnancy-related nausea. However, the product facts don't specify the ginger dose here, so you'd need to check with the manufacturer about whether there's enough to help. Either way, if you're pregnant, check with your doctor first.
What are the most common side effects I might notice?
Ginger can cause heartburn, diarrhea, stomach discomfort, or a peppery taste in your mouth or throat, especially at higher doses. Perilla is generally well tolerated, though rare severe allergic reactions (anaphylaxis) have been reported with perilla seeds. Magnolia and Poria are usually well tolerated, though allergic reactions are possible.
Is this safe to take while I'm pregnant?
The safety data for pregnancy are incomplete or advise against use for all the main ingredients in this product. Magnolia, Pinellia, Poria, and Perilla all lack enough safety information or are cautioned against in pregnancy. Ginger is sometimes used for morning sickness but should only be taken under your doctor's guidance. Talk with your OB or pharmacist for personalized advice.
Is this safe while breastfeeding?
No reliable safety data exist for any of the main ingredients while breastfeeding, so avoidance is recommended. Talk with your doctor or pharmacist before taking this product if you're nursing.
Can this product lower my blood sugar?
Ginger may increase insulin levels and lower blood glucose, so theoretically it could add to the effect of diabetes medications and increase the risk of low blood sugar. If you take diabetes medication, check with your pharmacist before starting this product.
