HelloPharmacist Scorecard of David Winston's Uterine Tonic by Herbalist & Alchemist

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 7 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (3 mL) without saying how much of each component you get.

This tonic is a liquid blend of 7 ingredients. The active herbs are Saw Palmetto berry extract, Cinnamon bark extract, Cyperus root extract, Dong Quai root extract, Chaste Tree berry extract, Chinese Peony root extract, and Shepherd's Purse whole plant extract.

The liquid also contains ethyl alcohol, distilled water, and vegetable glycerin as inactive ingredients.

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: Supports uterine circulation.
  • We looked for evidence on: Dysmenorrhea, Menorrhagia, Amenorrhea, Infertility, Menopausal symptoms, Postpartum complications — and 4 related terms.
  • The closest evidence on file: Peony is rated "Insufficient Reliable Evidence To Rate" for Dysmenorrhea (Natural Medicines).
  • Also on file: Shepherd's Purse is rated "Insufficient Reliable Evidence To Rate" for Postpartum complications, Menorrhagia.
  • Also on file: Dong Quai is rated "Insufficient Reliable Evidence To Rate" for Menopausal symptoms, Dysmenorrhea, Infertility.

The evidence for these herbs is not established in our data. Saw Palmetto shows possibly ineffective for benign prostatic hyperplasia and possibly effective for one specific prostate procedure, but the others—including all the ingredients in this tonic's intended use—carry insufficient reliable evidence to rate.

We simply don't have strong clinical data on whether this blend works for uterine support or any other purpose.

The evidence, ingredient by ingredient Saw Palmetto Cassia Cinnamon Adrue Dong Quai Vitex Agnus-castus Peony Shepherd's Purse

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 6 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 these herbs are generally well tolerated in short-term use when taken alone. Saw Palmetto can cause mild side effects like abdominal pain, constipation, diarrhea, dizziness, headache, nausea, or rarely heart rhythm changes or drug rash.

Cinnamon can trigger rash or allergic reactions in sensitive people. Chinese Peony commonly causes stomach upset—diarrhea, nausea, bloating.

Dong Quai is well tolerated but can cause burping and raises sun sensitivity. Saw Palmetto, Dong Quai, Shepherd's Purse, and Chinese Peony all advise against use in pregnancy due to potential uterine stimulation or hormone effects.

Saw Palmetto and Dong Quai should be avoided while breastfeeding. Cinnamon is likely safe in food amounts during pregnancy but avoid supplement doses.

Peony and Shepherd's Purse lack enough safety data for breastfeeding, so avoid them as well.

Meds to double-check

Major interaction found
Known Interaction Concern · database check
Major identified

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

Why this rating?
  • 7 of the 7 matched ingredients can interact with medications — Peony, Adrue, Shepherd's Purse, Dong Quai, Vitex Agnus-castus, among others.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.
  • For scale: 1,229 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.

Blood thinners like warfarin are a top concern: Dong Quai can increase bleeding risk significantly. Check before use if you take any blood thinner or antiplatelet drug (ibuprofen, aspirin, etc.), birth control pills or hormone replacement, diabetes medicine, sedatives or anti-anxiety drugs, seizure medicine like phenytoin, thyroid hormone, or psychiatric drugs like clozapine.

The bottom line

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

This is a traditional herbal blend aimed at women's reproductive health, but we don't have strong evidence it works. More importantly, several ingredients interact with common medications—especially blood thinners, birth control, diabetes drugs, and thyroid medicines.

If you're pregnant, breastfeeding, or take any regular medications, talk with your pharmacist or doctor before adding this tonic.

For each ingredient in David Winston's Uterine Tonic 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.

Chinese Peony 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

Cinnamon bark extract2 drug types · 442 drugs

Antidiabetes Drugs

Theoretically, cassia cinnamon may have additive effects with antidiabetes drugs.
Cassia cinnamon may lower blood glucose levels, and have additive effects in patients treated with antidiabetic agents. Dose adjustments to diabetes medications might be necessary.

Likelihood Possible Evidence B
Hepatotoxic Drugs

Theoretically, large doses of cassia cinnamon might cause additive effects when used with hepatotoxic drugs.
There is some concern that ingesting large amounts of cassia cinnamon for an extended duration might cause hepatotoxicity in some people. Cassia cinnamon contains coumarin, which can cause hepatotoxicity in animal models. In humans, very high doses of coumarin from 50-7000 mg/day can result in hepatotoxicity that resolves when coumarin use is discontinued. Lower amounts might also cause liver problems in sensitive people, such as those with liver disease or those taking potentially hepatotoxic agents.

Shepherd's Purse whole plant extract2 drug types · 264 drugs

Cns Depressants

Theoretically, concomitant use with drugs with sedative properties may cause additive effects and side effects.

Likelihood Possible Evidence D
Thyroid Hormone

Theoretically, concomitant use may interfere with thyroid dysfunction therapy.

Likelihood Possible Evidence D
Shepherd's Purse whole plant extract full monograph & interactions

Cyperus root 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.

Saw Palmetto berry extract3 drug types · 174 drugs

Anticoagulant/Antiplatelet Drugs

Saw palmetto might increase the risk of bleeding with anticoagulant or antiplatelet drugs.
Saw palmetto is reported to prolong bleeding time. Theoretically, it might increase the risk of bleeding when used concomitantly with anticoagulant or antiplatelet drugs.

Likelihood Possible Evidence D
Contraceptive Drugs

Saw palmetto might reduce the effectiveness of contraceptive drugs.
Saw palmetto might have antiestrogenic effects. Theoretically, it might interfere with contraceptive drugs taken concomitantly.

Saw palmetto might reduce the effectiveness of estrogens.
Saw palmetto might have antiestrogenic effects. Theoretically, it might interfere with estrogens taken concomitantly.

Likelihood Possible Evidence B
Saw Palmetto berry extract full monograph & interactions

Dong Quai 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.

Antipsychotic Drugs

Theoretically, vitex agnus-castus could interfere with the activity of antipsychotic drugs.
Vitex agnus-castus might interfere with the action of dopamine antagonists such as antipsychotic drugs due to its dopamine agonist effects.

Likelihood Possible Evidence D
Contraceptive Drugs

Theoretically, vitex agnus-castus could interfere with oral contraceptives.
Vitex agnus-castus might interfere with the efficacy of oral contraceptives due to possible hormone modulating activity.

Likelihood Possible Evidence B
Dopamine Agonists

Theoretically, vitex agnus-castus could interfere with dopamine agonists.
Vitex agnus-castus might potentiate the actions of dopaminergic agonists due to possible dopaminergic effects.

David Winston's Uterine Tonic by Herbalist & Alchemist: Common Questions

Does David Winston's Uterine Tonic by Herbalist & Alchemist interact with any medications?
Yes. Based on its ingredients, David Winston's Uterine Tonic has a known interaction with 1,228 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?
David Winston's Uterine Tonic contains 7 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 on birth control?
No—not without checking with your pharmacist first. Saw Palmetto and Chinese Peony may reduce birth control effectiveness or raise estrogen-related side effects. You'll need to discuss this with your doctor or pharmacist to decide if it's safe for you.
Is this safe during pregnancy?
No. Saw Palmetto, Dong Quai, Shepherd's Purse, and Chinese Peony all advise against pregnancy use because they may stimulate the uterus or affect hormones. Talk with your OB or midwife before considering any herbal supplement while pregnant.
What are the side effects?
The most common are stomach upset—nausea, bloating, diarrhea—especially from Peony. Saw Palmetto can cause headache, dizziness, or constipation. Dong Quai may cause burping and increase sun sensitivity. Shepherd's Purse traditionally raises concerns about blood pressure and heart rhythm, though human data are limited.
Does this actually work for uterine health?
The evidence isn't established in our data. None of these herbs have strong clinical proof for the purposes this blend claims. Traditional use is not the same as proven effectiveness.
Can I take this while breastfeeding?
No. Saw Palmetto, Dong Quai, Shepherd's Purse, and Chinese Peony all lack enough safety data for breastfeeding. It's best to avoid them while nursing—talk with your doctor about safer alternatives.
What if I take thyroid medicine?
Shepherd's Purse may theoretically interfere with thyroid hormone therapy. Check with your pharmacist before starting this tonic if you take thyroid medication.
