HelloPharmacist Scorecard of Organic Dong Quai by Five Flavors Herbs

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

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: dong quai root extract, a traditional herb used in Chinese medicine. The liquid also includes water and cane alcohol as inactive ingredients that help deliver the extract.

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 — see Dong Quai's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: promotes reproductive balance.
  • We looked for evidence on: Dysmenorrhea, Menopausal symptoms, Premenstrual syndrome (PMS), Infertility, menstrual irregularity, women's health — and 1 related terms.
  • The closest evidence on file: Dong Quai is rated "Insufficient Reliable Evidence To Rate" for Menopausal symptoms (Natural Medicines).
  • Also on file: Dong Quai is rated "Insufficient Reliable Evidence To Rate" for Premenstrual syndrome (PMS), Dysmenorrhea, Infertility.

The evidence for dong quai is not established in our data. We hold insufficient reliable evidence to rate it for iron deficiency anemia, osteoporosis, coronary heart disease, migraine headache, or eczema — the conditions most often cited.

That doesn't mean it doesn't work; it means rigorous studies haven't yet proven it does.

The evidence, ingredient by ingredient Dong Quai

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 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Dong quai is generally well-tolerated when taken by mouth; burping and flatulence are the most common side effects. However, it may increase bleeding risk and can make your skin more sensitive to sunlight.

The safety data advises against use during pregnancy because it may stimulate the uterus and affect bleeding. There isn't enough safety information on file to recommend it while breastfeeding — talk with your doctor or pharmacist for personalized guidance if you're nursing.

Additionally, dong quai contains some constituents linked to cancer in lab studies, though it's unclear whether the amounts in this product would pose a real risk with long-term or high-dose use.

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?
  • 1 of the 1 matched ingredient can interact with medications — Dong Quai.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 163 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 you take this product, double-check warfarin and other blood thinners (anticoagulants) with your pharmacist — this is a Major risk. Also check antiplatelet drugs and estrogen-based hormone therapy.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Major medication interactions have been identified, and safety information is well characterized.

If you don't take warfarin, other blood thinners, antiplatelet drugs, or hormone therapy, dong quai may be worth discussing with your pharmacist. If you're pregnant or breastfeeding, the safety data advises caution or avoidance — talk to your doctor before use.

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.
