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 Oct 8, 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, the part of the herb that gives the product its purpose. Its inactive ingredients are purified water and cane alcohol.

Inactive ingredients are the non-active parts of a product, such as the liquid base and any alcohol used in the formula. They do not provide the herbal effect, but they are still listed on the label so you know what is in the bottle.

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: Infertility, Menopausal symptoms, Dysmenorrhea, Premenstrual syndrome (PMS), Irregular menstruation, Reproductive 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.

Dong quai has been rated for several uses, including iron deficiency anemia, osteoporosis, coronary heart disease, migraine headache, and atopic dermatitis (eczema). For every one of these, the rating is Insufficient Reliable Evidence To Rate, which means the evidence is not established in the data we hold.

In practical terms, we cannot tell you that dong quai helps with any of these conditions. If you are considering it for one of them, talk it over with your own doctor or pharmacist.

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 orally, though the most common side effects are burping and flatulence. Our safety notes also flag that it may increase bleeding and can cause skin sensitivity to sunlight, so use it with care.

A pharmacist once developed allergic asthma and rhinitis after occupational exposure to dong quai and other herbs. Dong quai contains constituents that are carcinogenic (cancer-causing in some settings).

It is unknown whether they are present in amounts large enough to cause cancer with long-term or high-dose use.

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?
  • 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.

Double-check warfarin (Coumadin), a blood thinner, first, since it carries the Major severity rating. Next, review estrogens and anticoagulant or antiplatelet drugs, both rated Moderate.

Confirm your full medication list with your own doctor or pharmacist before taking this product.

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.

Dong quai may be of interest to adults looking for an herbal liquid, but the evidence for its uses is not established in the data we hold. Anyone taking warfarin, estrogens, or other blood-clotting medicines should be especially careful.

Please talk this over with your own doctor or pharmacist before starting, stopping, or combining it with anything else.

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.
