HelloPharmacist Scorecard of Fertile Fields 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 10 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.

Fertile Fields Teapills contains 10 active ingredients, most of them botanical extracts drawn from traditional Chinese medicine: dong quai root, rehmannia root, Baikal skullcap root, Eucommia bark, nutgrass rhizome, lovage rhizome, Dipsacus root, mugwort leaf, donkey gelatin, and peony root. Each plays a role in the traditional herbal formulation, though the product's actual effectiveness for its stated purposes hasn't been reliably established in modern research.

The tablet also contains inactive ingredients—microcrystalline cellulose, hydrated magnesium silicate, maltose, and China wax—which are binders and fillers that hold the pill 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: Women's fertility and reproductive health.
  • We looked for evidence on: Dysmenorrhea, Premenstrual syndrome (PMS), Polycystic ovary syndrome (PCOS), Menopausal symptoms, Infertility, Uterine fibroids — and 4 related terms.
  • The closest evidence on file: Peony is rated "Insufficient Reliable Evidence To Rate" for Polycystic ovary syndrome (PCOS) (Natural Medicines).
  • Also on file: Peony is rated "Insufficient Reliable Evidence To Rate" for Premenstrual syndrome (PMS), Dysmenorrhea.
  • Also on file: Mugwort is rated "Insufficient Reliable Evidence To Rate" for Dysmenorrhea.

The data we hold shows insufficient reliable evidence to rate most of what Fertile Fields Teapills is used for—iron deficiency anemia, osteoporosis, heart disease, migraines, and eczema all fall into that category for dong quai and several other ingredients. Rehmannia is rated possibly effective for chronic kidney disease, one of the few positive effectiveness ratings in this formula.

Gelatin is rated possibly ineffective for diarrhea. Overall, this is a traditional herbal blend with limited modern research backing its specific health claims.

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

Most of the individual ingredients are generally well tolerated when used orally, though side effects can occur. Dong quai may cause burping and flatulence, and it can make your skin more sensitive to sunlight, so use with care.

Baikal skullcap can trigger abdominal pain, constipation, diarrhea, nausea, or vomiting in some people; rare cases of liver inflammation and a serious lung condition called hypersensitivity pneumonitis have been reported with one branded product containing Baikal skullcap. Peony may cause abdominal bloating, loss of appetite, diarrhea, or nausea.

Gelatin can cause belching, bloating, and indigestion, and allergic reactions including hives and in rare cases anaphylaxis are possible. None of these ingredients have adequate safety data in pregnancy—dong quai may stimulate the uterus and affect bleeding—or breastfeeding.

Talk to your doctor or pharmacist before using this product if you're pregnant, nursing, or planning to become pregnant.

Scutellaria baicalensis Root Extract12 drug types · 946 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, Baikal skullcap might increase the risk of bleeding when used concomitantly with anticoagulant and antiplatelet drugs.
Preliminary clinical research suggests that taking capsules containing a combination of astragalus, goldthread, and Baikal skullcap daily for 4 weeks inhibits platelet aggregation; the effect seems to be similar to that of aspirin 50 mg daily. It is unclear if this effect is due to Baikal skullcap, other ingredients, or the combination.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, concomitant use of Baikal skullcap with antidiabetes drugs might enhance blood glucose lowering effects.
Baicalein, a constituent of Baikal skullcap, has alpha-glucosidase inhibitory activity in vitro. Animal research also suggests that Baikal skullcap enhances the antidiabetic effects of metformin. However, in a small human study, taking Baikal skullcap extract did not enhance the antidiabetic effects of metformin, although it did modestly lower glucose levels during an oral glucose tolerance test (OGTT). Until more is known, use cautiously.

Likelihood Possible Evidence B
Antihypertensive Drugs

Theoretically, concomitant use of Baikal skullcap with antihypertensive drugs might have additive effects and increase the risk of hypotension.
Animal research suggests that baicalein, a constituent of Baikal skullcap, might lower blood pressure.

Likelihood Possible Evidence D
Antithyroid Drugs

Theoretically, concomitant use of Baikal skullcap and antithyroid drugs may result in additive activity and increase the risk of hypothyroidism.
In an animal hyperthyroid model, Baikal skullcap improved levels of triiodothyronine (T3), thyroxine (T4), and thyroid stimulating hormone (TSH). The clinical significance of this effect is unclear.

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

Theoretically, Baikal skullcap may increase levels of drugs metabolized by CYP1A2 enzymes.
In vitro evidence suggests that constituents of Baikal skullcap inhibit the activity of CYP1A2. This effect has not been reported in humans.

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

Theoretically, Baikal skullcap might increase levels of drugs metabolized by CYP2C19 enzymes.
In vitro evidence suggest that wogonin, a constituent of Baikal skullcap, modestly inhibits the activity of CYP2C19 enzymes. This effect has not been reported in humans.

Likelihood Possible Evidence D
Estrogens

Theoretically, concomitant use of large amounts of Baikal skullcap might interfere with hormone replacement therapy, due to competition for estrogen receptors.
In vitro evidence suggests that Baikal skullcap has estrogenic activity.

Likelihood Possible Evidence D
Lithium

Theoretically, Baikal skullcap might reduce lithium excretion and increase serum levels of lithium.
Baikal skullcap is thought to have diuretic properties, which may reduce lithium excretion. The dose of lithium might need to be decreased.

Likelihood Possible Evidence D
Alcohol (Ethanol)

Theoretically, Baikal skullcap might potentiate the sedative effects of alcohol.
In vitro and animal research suggests that Baikal skullcap binds to GABA-A receptors and causes sedation. Theoretically, Baikal skullcap might potentiate the sedative effects of alcohol. Preliminary clinical research has not identified clinically relevant sedation after use of Baikal skullcap; however, a thorough evaluation of safety outcomes has not been conducted.

Likelihood Unlikely Evidence D
Cns Depressants

Theoretically, Baikal skullcap might cause additive therapeutic and adverse effects when used concomitantly with drugs with sedative properties.
In vitro and animal research suggests that Baikal skullcap binds to GABA-A receptors and causes sedation. Theoretically, Baikal skullcap might cause additive therapeutic and adverse effects when used concomitantly with drugs with sedative properties. Preliminary clinical research has not identified clinically relevant sedation after use of Baikal skullcap; however, a thorough evaluation of safety outcomes has not been conducted.

Likelihood Unlikely Evidence D
Organic Anion-Transporting Polypeptide Substrates (Oatp)

Theoretically, Baikal skullcap might alter the levels and clinical effects of OATP substrates.
Some pharmacokinetic research shows that baicalin, a constituent of Baikal skullcap, can decrease plasma levels of rosuvastatin. The mechanism is thought to involve stimulation of the activity of the organic anion-transporting polypeptide 1B1 (OATP1B1), which transports rosuvastatin into the liver. This decreases plasma levels of the drug, but increases levels at the site of action in the liver. The degree to which rosuvastatin levels are affected depends on the OATP1B1 haplotype of the individual. Baikal skullcap might also affect other OATP1B1 substrates.

Likelihood Possible Evidence B
P-Glycoprotein Substrates

Theoretically, Baikal skullcap might increase levels of drugs transported by P-glycoprotein.
In vitro and animal research suggests that baicalein, oroxylin A, and wogonin, constituents of Baikal skullcap, can inhibit P-glycoprotein. This effect has not been reported in humans.

Likelihood Possible Evidence D

Paeonia lactiflora Root 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.

Likelihood Probable Evidence D

Rehmannia glutinosa Root 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).

Likelihood Possible Evidence D

Cyperus rotundus Rhizome Extract3 drug types · 256 drugs

Barbiturates

Animal research suggests that taking adrue in combination with sodium thiopental increases total sleep time three-fold compared to the effects of sodium thiopental alone. Theoretically, concomitant use of adrue and barbiturates might increase the risk of drowsiness and motor reflex depression. Some barbiturates include amobarbital (Amytal), butabarbital (Butisol), mephobarbital (Mebaral), pentobarbital (Nembutal), phenobarbital (Luminal), secobarbital (Seconal), and others.

Likelihood Possible Evidence D
Benzodiazepines

Animal research suggests that taking adrue in combination with diazepam increases total sleep time four-fold compared to the effects of diazepam alone. Theoretically, concomitant use adrue and benzodiazepines might increase the risk of drowsiness and motor reflex depression. Some benzodiazepines include clonazepam (Klonopin), diazepam (Valium), lorazepam (Ativan), and others.

Likelihood Possible Evidence D
Cns Depressants

Animal research suggests that taking adrue in combination with sodium thiopental or diazepam increases total sleep time up to four-fold compared to the effects of the drugs alone. Theoretically, concomitant use of adrue with CNS depressants might cause additive sedation. Some CNS depressants include benzodiazepines, such as diazepam (Valium), alprazolam (Xanax), triazolam (Halcion), and estazolam (ProSom); barbiturates, such as mephobarbital (Mebaral), phenobarbital (Luminal Sodium), and pentobarbital sodium (Nembutal); zolpidem (Ambien); and others.

Likelihood Possible Evidence D

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.

Fertile Fields Teapills by Plum Flower: Common Questions

Does Fertile Fields Teapills by Plum Flower interact with any medications?
Yes. Based on its ingredients, Fertile Fields Teapills has a known interaction with 1,259 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?
Fertile Fields Teapills contains 10 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 Fertile Fields Teapills safe to use while pregnant or breastfeeding?
No. Dong quai may stimulate the uterus and affect bleeding during pregnancy, and safety data for rehmannia, Baikal skullcap, and peony in pregnancy are too limited—the advice is to avoid them. Breastfeeding safety information is also insufficient for these ingredients. Talk with your doctor or pharmacist about whether this product is right for you if you're pregnant, trying to conceive, or nursing.
What is dong quai, and why does it interact with blood thinners?
Dong quai (Angelica sinensis) is a root used in traditional Chinese herbal medicine. It contains compounds with blood-thinning properties of their own; when combined with warfarin or other anticoagulants, it may increase bleeding risk beyond what the medication alone would cause. Case reports have documented this interaction, which is why it's Major severity.
What side effects might I experience?
Common ones are mild: burping, flatulence, belly bloating, constipation, diarrhea, nausea, and loss of appetite. Some people get skin sensitivity to sun exposure. Rarely, Baikal skullcap—one of the main ingredients—has been linked to liver inflammation and a serious lung condition called hypersensitivity pneumonitis. Gelatin can cause allergic reactions in sensitive people.
Does this product actually work for fertility or its other claimed uses?
The evidence isn't established. Our data shows insufficient reliable evidence to rate dong quai for anemia, bone health, heart disease, migraines, or eczema. Rehmannia is possibly effective for chronic kidney disease, but most of the other ingredients lack proven benefits in modern research.
Can I take this if I'm on birth control or hormone replacement therapy?
Not without checking with your pharmacist first. Dong quai, Baikal skullcap, and peony all contain compounds with estrogenic activity that may theoretically interfere with how your hormones work or reduce their effectiveness. Moderate interactions are documented.
What's gelatin, and why is it in here?
Gelatin is a protein derived from animal collagen—in this case, it's from donkey. It's used as a binder to hold the tablet together. It's generally well tolerated, but some people are allergic to gelatin, especially if they've been exposed to it in vaccines or other medicines before.
