HelloPharmacist Scorecard of Serene Spirit 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.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 11, 2026

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 6 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.

Serene Spirit Teapills contains six active ingredients in a proprietary blend. The main component is fo-ti stem extract (also called He shou wu), a traditional herb; the other actives are extracts from wheat fruit, poria mushroom sclerotium, jujube fruit, lily bulb, and Albizia julibrissin bark.

The product also contains several inactive ingredients: dextrin, magnesium silicate, activated charcoal, china wax, and wheat.

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 and calming support.
  • We looked for evidence on: Insomnia, Anxiety, Stress, Mood support.
  • 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 we hold for Serene Spirit Teapills does not establish effectiveness for any condition. Fo-ti is listed for age-related cognitive decline, Alzheimer disease, hair loss (androgenic alopecia), osteoporosis, and heart disease — but all carry an Insufficient Reliable Evidence rating.

Poria mushroom extract is similarly unrated for cancer, fatigue, dementia, diabetes, diabetic kidney disease, and diarrhea. No effectiveness data are on file for the wheat fruit, jujube, lily bulb, or Albizia ingredients.

Traditional use does not equal proven benefit in clinical trials.

The evidence, ingredient by ingredient Fo-ti Wheatgrass Poria Mushroom Zizyphus Albizia Julibrissin

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.

Fo-ti is the key safety concern in this product. It has been linked to around 450 documented cases of liver injury — ranging from hepatitis to cirrhosis — in people of all ages and at varying doses and formulation types, both processed and unprocessed.

Gastrointestinal side effects (stomach pain, diarrhea, nausea, vomiting) are most common, especially with unprocessed fo-ti. Poria mushroom is generally well tolerated based on traditional use, though human safety data are limited; rare allergic reactions including allergic rhinitis and asthma have been reported.

Albizia julibrissin has limited human safety data as well. None of these ingredients should be used during pregnancy — safety is not established.

Fo-ti, poria, and Albizia are all best avoided while breastfeeding due to insufficient safety information.

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 — Zizyphus, Poria Mushroom, Fo-ti, Wheatgrass, Albizia Julibrissin.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications; heart-rhythm medications.
  • For scale: 1,430 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 Serene Spirit Teapills, double-check with your pharmacist if you take blood thinners or antiplatelet drugs (especially warfarin), heart medications like digoxin, sedatives or other CNS depressants, anti-inflammatory drugs like sulindac, anticholinergic or cholinergic medications, diuretics, or any drugs metabolized by your liver — the interactions are Moderate and documented.

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.

This product may appeal to those interested in traditional herbal support, but it carries real risks that demand careful consideration. If you take a blood thinner, heart medication, sedative, diuretic, or any prescription drug, talk to your pharmacist before trying it — the interactions are documented and potentially serious.

Liver safety is a significant concern with fo-ti. Because this is not an urgent medical need with proven benefit, pregnancy and breastfeeding are contraindications.

Polygonum multiflorum Stem Extract17 drug types · 1,257 drugs

Anticoagulant/Antiplatelet Drugs

Fo-ti has been linked to cases of acute liver failure which can decrease clotting factor production and increase the effects of anticoagulants. In one case, a patient who had been stable on warfarin presented with acute hepatitis and an INR elevated to 14.98. The patient had been taking fo-ti for 90 days prior to admission. Discontinuation of warfarin and fo-ti lead to a decrease in the INR and full recovery. Theoretically, concomitant use of fo-ti with anticoagulant or antiplatelet drugs may increase the risk of bleeding in some patients. Until more is known, monitor patients taking fo-ti and drugs that affect bleeding.
Some of these drugs include aspirin, clopidogrel (Plavix), dalteparin (Fragmin), dipyridamole (Persantine), enoxaparin (Lovenox), heparin, ticlopidine (Ticlid), warfarin (Coumadin), and others.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, fo-ti might increase the risk of hypoglycemia when taken with antidiabetes drugs.
Fo-ti reportedly has hypoglycemic effects.

Likelihood Possible Evidence D
Contraceptive Drugs

Theoretically, taking large amounts of fo-ti might interfere with contraceptive drugs due to competition for estrogen receptors.
In vitro research suggests that fo-ti extract has estrogenic activity.

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

Theoretically, fo-ti might increase or decrease the levels and clinical effects of drugs metabolized by CYP1A2.
In vitro research suggests that fo-ti might inhibit CYP1A2. Additionally, in vitro research suggests that the degree of CYP1A2 inhibition depends on the type of fo-ti extract (i.e., the raw plant leads to greater inhibition than extensively processed extracts). However, in an animal study, an aqueous extract of fo-ti inhibited CYP1A2 while an alcoholic extract of fo-ti induced CYP1A2. Induction or inhibition of CYP1A2 by fo-ti has not been reported in humans.

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

Theoretically, fo-ti might increase the levels and clinical effects of drugs metabolized by CYP2B6.
Animal research suggests that fo-ti might inhibit CYP2B6. One in vitro study suggests that the degree of CYP2B6 inhibition may depend on the type of fo-ti extract (i.e., the raw plant leads to greater inhibition than extensively processed extracts). However, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2C19 (Cyp2C19) Substrates

Theoretically, fo-ti may increase the levels and clinical effects of drugs metabolized by CYP2C19.
Animal and in vitro research suggests that fo-ti may inhibit CYP2C19. An in vitro study suggests that the degree of CYP2C19 inhibition may depend on the type of fo-ti extract (i.e., the raw plant leads to greater inhibition than extensively processed extracts). However, this interaction has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2C8 (Cyp2C8) Substrates

Theoretically, fo-ti might increase the levels and clinical effects of drugs metabolized by CYP2C8.
In vitro research suggests that fo-ti might inhibit CYP2C8. However, this interaction has not been reported in humans.

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

Theoretically, fo-ti may increase the levels and clinical effects of drugs metabolized by CYP2C9.
Animal and in vitro research suggests that fo-ti may inhibit CYP2C9. However, this interaction has not been reported in humans.

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

Theoretically, fo-ti may increase the levels and clinical effects of drugs metabolized by CYP2D6.
Animal research suggests that fo-ti might inhibit CYP2D6. Additionally, an in vitro study suggests that the degree of CYP2D6 inhibition may depend on the type of fo-ti extract (i.e., the raw plant leads to greater inhibition than extensively processed extracts). However, this interaction has not been reported in humans.

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

Theoretically, fo-ti might increase the levels and clinical effects of drugs metabolized by CYP3A4.
In vitro research suggests that fo-ti might inhibit CYP3A4. One in vitro study suggests that the degree of CYP3A4 inhibition may depend on the type of fo-ti extract (i.e., the raw plant leads to greater inhibition than extensively processed extracts). However, this evidence conflicts with animal research suggesting that fo-ti does not inhibit CYP3A4. This interaction has not been reported in humans.

Likelihood Possible Evidence D
Digoxin (Lanoxin)

Theoretically, fo-ti, particularly raw fo-ti root, might increase the risk of hypokalemia and cardiotoxicity when taken with digoxin.
Raw fo-ti root contains anthraquinone derivatives, which might have stimulant laxative effects. In vitro research shows that fermented and processed fo-ti root have reduced laxative effects compared with raw fo-ti root.

Likelihood Possible Evidence D
Diuretic Drugs

Theoretically, fo-ti, particularly raw fo-ti root, might increase the risk of hypokalemia when taken with diuretic drugs.
Raw fo-ti root contains anthraquinone derivatives, which might have stimulant laxative effects and compound diuretic-induced potassium loss. In vitro research shows that fermented and processed fo-ti root have reduced laxative effects compared with raw fo-ti root.

Likelihood Possible Evidence D
Estrogens

Theoretically, taking large amounts of fo-ti might interfere with hormone replacement therapy through competition for estrogen receptors.
In vitro research suggests that fo-ti extract has estrogenic activity.

Likelihood Probable Evidence D
Hepatotoxic Drugs

Theoretically, fo-ti might increase the risk of liver damage when taken with hepatotoxic drugs.
Fo-ti has been linked to liver damage in many reports.

Likelihood Possible Evidence D
Stimulant Laxatives

Theoretically, fo-ti, particularly raw fo-ti root, might increase the risk of fluid and electrolyte depletion when taken with stimulant laxatives.
Raw fo-ti root contains anthraquinone derivatives, which might have stimulant laxative effects. However, in vitro research shows that fermented and processed fo-ti root have reduced laxative effects compared with raw fo-ti root.

Likelihood Possible Evidence D
Sulindac (Clinoril)

Theoretically, fo-ti might increase or decrease the levels and clinical effects of sulindac.
Animal research suggests that the type of fo-ti extract might affect the levels of sulindac differently; the raw plant may increase levels, but processed parts may decrease levels. Induction or inhibition of CYP1A2 by fo-ti has not been reported in humans.

Likelihood Possible Evidence D
Warfarin (Coumadin)

Theoretically, fo-ti might increase the effects and adverse effects of warfarin.
Fo-ti may have stimulant laxative effects and cause diarrhea, especially when the raw or unprocessed fo-ti root is used. Diarrhea can increase the effects of warfarin, increase international normalized ratio (INR), and increase the risk of bleeding. Also, fo-ti has been linked to cases of acute liver failure which can decrease clotting factor production and increase the effects of warfarin. In one case, a patient who had been stable on warfarin presented with acute hepatitis and an INR elevated to 14.98. The patient had been taking fo-ti for 90 days prior to admission. Discontinuation of warfarin and fo-ti lead to a decrease in the INR and full recovery.

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.

Serene Spirit Teapills by Plum Flower: Common Questions

Does Serene Spirit Teapills by Plum Flower interact with any medications?
Yes. Based on its ingredients, Serene Spirit Teapills has a known interaction with 1,429 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Serene Spirit Teapills contains 6 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.
Is it safe to take fo-ti if I'm on warfarin?
No — fo-ti and warfarin together carry a Moderate interaction risk. Fo-ti can damage your liver, which affects how clotting factors work and can dangerously increase your blood-thinning level. There's a documented case where a patient's INR spiked to 14.98 after 90 days. Do not take this product if you're on warfarin without talking to your doctor or pharmacist first.
What are the main side effects of fo-ti?
The most common ones are stomach pain, diarrhea, nausea, and vomiting, especially with unprocessed fo-ti. More seriously, fo-ti can cause liver injury — around 450 cases have been documented in medical literature, ranging from mild hepatitis to cirrhosis. Liver damage has occurred at many different doses and durations of use.
Can I take this while pregnant or breastfeeding?
No. Safety is not established during pregnancy for any of the main ingredients — fo-ti, poria, and Albizia. While breastfeeding, there isn't enough safety data for any of them either, so avoidance is recommended. Talk to your doctor about what's right for you.
Does this product have fillers?
Yes. In addition to the six active herbal ingredients, it contains inactive ingredients: dextrin, magnesium silicate, activated charcoal, china wax, and wheat.
Does this product actually work for cognitive decline or memory?
We don't have reliable evidence to say so. Fo-ti is traditionally used for cognitive support and is listed for conditions like Alzheimer disease and age-related memory loss, but all the effectiveness ratings are insufficient — meaning the clinical evidence isn't strong enough to confirm a benefit.
Will poria mushroom make me drowsy?
It could if you're already taking sedatives or other drugs that depress the central nervous system — animal studies show poria has sedative properties, and theoretically it could enhance their effects. If you take any sleeping pills, antianxiety drugs, or sedating medications, check with your pharmacist first.
