HelloPharmacist Scorecard of Dong Quai (Chinese Angelica) Root 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 (Chinese Angelica) Root in powder form. There are no inactive fillers listed.
Does it work?
Couldn't assess
The evidence we hold does not establish that dong quai is effective for any of its claimed uses—iron-deficiency anemia, osteoporosis, heart disease, migraine, or eczema. All are rated as having insufficient reliable evidence to rate its benefit.
That doesn't mean it doesn't work; it means the science isn't settled yet in our data.
How safe is it?
Well-documented data
Dong quai is generally well tolerated by mouth, with burping and flatulence being the most common side effects reported. The main cautions: it may increase your bleeding risk and can make your skin more sensitive to sunlight, so use with care and sun protection.
The safety data advises against use during pregnancy because it may stimulate the uterus and affect bleeding. There isn't enough safety information to know whether it's safe while breastfeeding—talk with your doctor or pharmacist for personalized guidance.
One rare case of allergic asthma and stuffy nose occurred with occupational exposure. Dong quai also contains compounds with cancer-causing properties in lab studies, though whether the amounts in this powder are large enough to matter with long-term or high-dose use is unknown.
Meds to double-check
Major interaction found
Before taking this product, double-check with your doctor or pharmacist if you take warfarin or any other blood thinner (anticoagulant or antiplatelet drug)—the Major and Moderate risk of increased bleeding is real and documented. Also check if you use estrogen-based hormone replacement therapy or birth control, since dong quai may interfere with how well they 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 Root Powder is generally well tolerated, but it's mainly a wait-and-see product on effectiveness—the evidence we have doesn't yet support its traditional uses. Its real concern is if you take blood thinners or hormones; in those cases, don't start this without checking with your doctor or pharmacist first.
Avoid it in pregnancy, and be cautious in the sun.

HelloPharmacist Interaction Report
Dong Quai Root Powder by TerraVita Premium Collection has documented interactions with blood thinners and hormone medications.
The most serious concern is warfarin (Coumadin), a blood thinner: case reports show that dong quai can boost warfarin's blood-thinning effect and raise your bleeding risk. One case documented a significant increase in INR—the lab measure of how thin your blood is—after just 4 weeks of use.
Read the full breakdown — every affected drug type, severity by severity
Dong quai may also increase bleeding risk with other anticoagulants and antiplatelet drugs (the broader class of blood thinners and clot-fighting medications). Animal studies suggest it has compounds that interfere with clotting, though the human evidence is mixed.
Additionally, dong quai has mild estrogen-like activity and may theoretically reduce how well hormone replacement therapy or birth control works by competing for the same receptors your body uses to respond to those hormones.
Always check your exact medications with the search tool on this page before starting. If you take any blood thinner or hormone medication, discuss this product with your doctor or pharmacist first.

For each ingredient in Dong Quai (Chinese Angelica) Root 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, 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.
