• Atopic dermatitis (eczema). Although there is interest in using oral dong quai for atopic dermatitis, there is insufficient reliable information about the clinical effects of dong quai for this condition.
• Chronic kidney disease (CKD). There is limited evidence on the use of dong quai in patients with CKD. Details: A large propensity score-matched observational study over 15 years in Taiwanese adults with CKD suggests that taking dong quai is associated with a 5.1% risk of end-stage renal disease (ESRD) and 38% risk of overall mortality when compared with 7% and 56%, respectively, in controls. Higher cumulative doses (i.e., 15 grams or more) and longer duration of exposure (i.e., > 60 days) are also associated with fewer ESRD events (112362). However, the interpretation of these findings is limited by the lack of exact dosage information and retrospective study design.
• Coronary heart disease (CHD). Intravenous dong quai has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in patients with CHD shows that injecting 20 mL of an intravenous solution containing dong quai, ginseng, and astragalus (Yi-qi Huo-xue Injection) daily for 2 weeks reduces the frequency and severity of angina episodes when compared with placebo. It also seems to increase exercise tolerance and improve left ventricular function when compared with placebo (33046). It is unclear if these benefits are due to dong quai, other ingredients, or the combination.
• Dysmenorrhea. Although there is interest in using oral dong quai for dysmenorrhea, there is insufficient reliable information about the clinical effects of dong quai for this condition.
• Hypertension. Although there is interest in using oral dong quai for hypertension, there is insufficient reliable information about the clinical effects of dong quai for this purpose.
• Idiopathic interstitial pneumonia. Oral dong quai has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A meta-analysis of 17 studies conducted in China in patients with idiopathic interstitial pneumonia concludes that adding traditional Chinese medicine combinations containing dong quai root and astragalus root to treatment with conventional medicines improves pulmonary function index, six-minute walking distance, and the Borg scale of perceived exertion when compared with conventional treatment alone (103618). The included studies are of low quality, include a range of treatment durations from 1-12 months, and vary in the conventional medicines and Chinese herb combinations used. The doses of dong quai used were not stated.
• Infertility. Although there is interest in using oral dong quai for infertility, there is insufficient reliable information about the clinical effects of dong quai for this condition.
• Iron deficiency anemia. Although there is interest in using oral dong quai for iron deficiency anemia, there is insufficient reliable information about the clinical effects of dong quai for this condition.
• Menopausal symptoms. There is inconsistent and contradictory evidence about the effect of dong quai on menopausal symptoms. Benefits have only been seen when it is used in combination with other ingredients; its effect when used alone is unclear. Details: Some clinical research shows that taking dong quai, 1.5 grams three times daily for 24 weeks, does not affect menopausal symptoms (738). Other clinical research shows that dong quai improves menopausal symptoms when used in combination with other constituents. In one clinical trial, taking five chewable tablets of a specific combination of dong quai and chamomile (Climex) daily for 12 weeks reduced the frequency and severity of hot flushes when compared with placebo (48445). In another trial, taking a combination providing dong quai 75 mg, along with American ginseng, black cohosh, milk thistle, red clover, and vitex agnus-castus (Phyto-Female Complex) twice daily for 3 months reduces menopausal symptoms, including the number and intensity of hot flushes, the number of night sweats, and sleep quality (19552). Taking another combination product containing dong quai, burdock root, licorice root, motherwort, and Mexican wild yam root, 500 mg three times daily for 3 months, also reduces menopausal symptoms when compared with placebo (48522). It is unclear if the beneficial effects in these studies were due to dong quai, other ingredients, or a combination of ingredients.
• Migraine headache. Oral dong quai has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: Preliminary clinical research in patients with menstrual migraine shows that taking a combination of soy isoflavones 60 mg, dong quai 100 mg, and black cohosh 50 mg daily for 24 weeks reduces the frequency of attacks when compared with placebo (35797). It is unclear if this effect is due to dong quai, other ingredients, or the combination.
• Osteoporosis. Although there is interest in using oral dong quai for osteoporosis, there is insufficient reliable information about the clinical effects of dong quai for this condition.
• Peptic ulcers. Although there is interest in using oral dong quai for peptic ulcers, there is insufficient reliable information about the clinical effects of dong quai for this condition.
• Premature ejaculation. Topical dong quai has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: In one preliminary clinical trial in patients with premature ejaculation, a multi-ingredient cream preparation (SS Cream) containing dong quai, Panax ginseng root, Cistanches deserticola, Zanthoxyl species, Torlidis seed, clove flower, Asiasari root, cinnamon bark, and toad venom was applied to the glans penis 1 hour prior to intercourse and washed off immediately before intercourse. Patients using the cream had significantly improved ejaculatory latency when compared with placebo cream (2537). It is unclear if this effect is due to dong quai, other ingredients, or the combination.
• Premenstrual syndrome (PMS). Although there is interest in using oral dong quai for PMS, there is insufficient reliable information about the clinical effects of dong quai for this condition.
• Psoriasis. Although there is interest in using oral dong quai for psoriasis, there is insufficient reliable information about the clinical effects of dong quai for this condition.
• Pulmonary hypertension. Preliminary clinical research shows that intravenous dong quai may be effective in patients with pulmonary hypertension. Details: Some preliminary clinical research in patients with chronic obstructive pulmonary disease (COPD) and pulmonary hypertension shows that intravenous administration of 250 mL of a solution containing dong quai 25%, once daily for 5-10 days, reduces pulmonary arterial pressure and pulmonary vascular resistance when compared to baseline (48438,48442,48443). The validity of these findings is limited by the lack of comparator groups.
• Rheumatoid arthritis (RA). Although there is interest in using oral dong quai for RA, there is insufficient reliable information about the clinical effects of dong quai for this condition.
• Stroke. Preliminary evidence does not support the use of intravenous dong quai for acute ischemic stroke. Details: Preliminary clinical research in patients with acute ischemic stroke shows that administering 200 mL of a solution containing dong quai 25% intravenously daily for 20 days does not improve neurological symptoms when compared with dextran-40 (48483). More evidence is needed to rate dong quai for these uses.

ANTICOAGULANT/ANTIPLATELET DRUGS Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, dong quai may increase the risk of bleeding when used with anticoagulant or antiplatelet drugs; however, research is conflicting.  Details Animal studies suggest that dong quai has antithrombin activity and inhibits platelet aggregation due to its coumarin components (6048,10057,96137). Additionally, some case reports in humans suggest that dong quai can increase the anticoagulant effects of warfarin (3526,6048,23310,48439). 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 (96137). Until more is known, use dong quai with caution in patients taking antiplatelet/anticoagulant drugs.

ESTROGENS Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, dong quai may reduce the effects of estrogens.  Details Dong quai has estrogenic effects (6180,7860,15108,15535,48459). Theoretically, concomitant use of large amounts of dong quai might interfere with hormone replacement therapy due to competition for estrogen receptors.

WARFARIN (Coumadin) Interaction Rating = Major Do not take this combination. Severity = High •  Occurrence = Probable •  Level of Evidence = D Dong quai may increase the risk of bleeding when used with warfarin.  Details Case reports suggest that concomitant use of dong quai with warfarin can increase the anticoagulant effects of warfarin and increase the risk of bleeding (3526,6048,23310,48439). 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 (3526).
