HelloPharmacist Scorecard of Dong Quai 4:1 Extract Powder by TerraVita Premium Collection
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
Full disclosure
This product contains one active ingredient: Dong Quai Extract in a 4:1 concentrated powder form. Dong quai is a plant root used traditionally in herbal medicine.
There are no other active ingredients, and no inactive fillers are listed.
Does it work?
Couldn't assess
The evidence we hold does not establish that dong quai is effective for the conditions it's marketed for—iron deficiency anemia, osteoporosis, heart disease, migraine, and eczema all carry insufficient evidence ratings in our data. That doesn't mean it doesn't work; it means reliable research supporting those uses isn't available in the sources we review.
How safe is it?
Well-documented data
Dong quai is generally well tolerated by mouth, though some people report burping and flatulence. The herb can increase bleeding risk and make your skin more sensitive to sunlight, so use with care if you're in the sun.
The safety data advises against using it during pregnancy because it may stimulate the uterus and affect bleeding. There isn't enough safety data to recommend it while breastfeeding, so talk with your doctor or pharmacist before use if you're nursing.
Rarely, occupational exposure has triggered allergic asthma and rhinitis. Dong quai contains compounds linked to cancer in lab studies, but whether the amounts in this product pose a real risk with long-term or high-dose use is unknown.
Meds to double-check
Major interaction found
Check with your doctor or pharmacist before using this product if you take warfarin or any other blood thinner (anticoagulant or antiplatelet drug), or if you take estrogen-based medications like hormone replacement therapy. Dong quai may increase bleeding risk and may reduce how well hormones work.
The bottom line
Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Major medication interactions have been identified, and safety information is well characterized.
Dong Quai 4:1 Extract Powder is a single-ingredient herbal product whose effectiveness for its listed uses is not well established in our data. The main concern is interaction with blood thinners—especially warfarin—and potential interference with hormone medications.
If you take any blood thinner or hormone therapy, check with your doctor or pharmacist before starting this product. Pregnant women and nursing mothers should discuss it with their healthcare provider first.

HelloPharmacist Interaction Report
Dong Quai 4:1 Extract Powder by TerraVita Premium Collection interacts with blood thinners and hormone medications, with the most serious concern being warfarin.
Dong quai can increase warfarin's blood-thinning effects and raise your bleeding risk—case reports show this happened within weeks of use.
Read the full breakdown — every affected drug type, severity by severity
Anticoagulant and antiplatelet drugs (blood thinners beyond warfarin) carry a moderate interaction risk. Animal studies suggest dong quai can thin the blood further, though human evidence is mixed.
Estrogens—including hormone replacement therapy—may be less effective when taken with dong quai, since the herb itself has estrogen-like activity and may compete for how your body uses these hormones.
Altogehter, these interactions span 163 individual medications. Before starting this product, check your exact prescriptions—especially any blood thinner or hormone medication—with your pharmacist or doctor.

For each ingredient in Dong Quai 4:1 Extract Powder with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.
Dong Quai Extract, Powder
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.
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.
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.
