• 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.

POSSIBLY EFFECTIVE

• Hypercholesterolemia. Several small studies suggest that oral safflower oil, as a substitute for coconut oil, butter, or other animal fats in the diet, may reduce total and low-density lipoprotein (LDL) cholesterol levels in patients with or without hypercholesterolemia. Details: Three small clinical studies in patients with or without hypercholesterolemia show that substituting coconut oil, butter, or other animal fats in the diet with safflower oil (36% of total daily calories) for 4-6 weeks can lower levels of total and LDL cholesterol, but has no beneficial effects on high-density lipoprotein (HDL) cholesterol or triglycerides (25391,25393,72310).

• Coronary heart disease (CHD). Safflower oil, which is high in oleic acid, may be beneficial for reducing the risk of CHD when used to replace other dietary oils. Details: Some safflower oil products contain high quantities of oleic acid. In 2018, the US Food and Drug Administration (FDA) determined that it would allow a qualified health claim stating that consuming 1.5 tablespoons daily of oils containing at least 70% oleic acid may reduce the risk of CHD. In order to obtain any benefit, this oil must be used to replace fats and oils higher in saturated fat. However, the FDA has determined that this statement is based on supporting, rather than conclusive, evidence (98563).
• Cystic fibrosis. It is unclear if oral safflower oil is beneficial in children with cystic fibrosis. Details: A very small clinical study in children with cystic fibrosis shows that taking safflower oil 1 gram/kg daily for one year does not affect sweat chloride concentrations or disease severity when compared with age-matched controls (72281).
• Diabetes. Small clinical studies of oral safflower oil for improving glycemic control in patients with diabetes have yielded mixed results. Details: One very small clinical trial in patients with type 2 diabetes shows that taking safflower oil 10 grams daily for 3 weeks increases fasting blood glucose by 11% when compared to baseline. Insulin levels, insulin sensitivity, and lipid levels were not affected (13146). However, another small clinical study in obese, postmenopausal patients with type 2 diabetes shows that taking safflower oil 2 grams four times daily for 16 weeks decreases HbA1c by 0.64% and increases high-density lipoprotein (HDL) cholesterol by about 5 mg/dL when compared with conjugated linoleic acid (CLA) 2 grams four times daily. Insulin sensitivity and fasting blood glucose levels do not appear to be affected (94039). These differing outcomes may be due to the small study sizes and varied patient populations.
• Diabetic nephropathy. Small clinical studies suggest that intravenous safflower yellow, a component of safflower flower, might improve symptoms and markers of diabetic nephropathy. Details: A meta-analysis of 14 small and low-quality clinical studies in adults with diabetic nephropathy shows that intravenous administration of safflower yellow as an adjunct to conventional treatment reduces urinary albumin excretion rate, fasting blood glucose, serum creatinine, and blood urea nitrogen when compared with conventional treatment alone. Overall, patients receiving safflower yellow were more likely to experience a clinical improvement in symptoms when compared with conventional treatment alone (102381).
• Familial hypercholesterolemia. Small clinical studies suggest that substituting safflower oil in place of butter in the diet may modestly reduce cholesterol levels in patients with familial hypercholesterolemia. Details: Two very small clinical studies in patients with familial hypercholesterolemia show that substituting safflower oil in place of butter in the diet (contributing 36% of daily calories) for 3 weeks decreases total and low-density lipoprotein (LDL) cholesterol levels when compared with butter (72246,72267).
• Hepatitis C. Oral safflower oil has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small, open-label clinical study in patients with chronic hepatitis C shows that taking a specific combination product containing safflower, pumpkin seeds, plantain seeds, and Japanese honeysuckle (EH0202) 1 gram daily for 3 months modestly reduces general discomfort, abdominal bloating, nausea, and vomiting when compared to baseline. However, hepatitis C RNA and hepatitis C virus antibody levels are not affected (72238).
• Hypertension. It is unclear if oral safflower oil is beneficial for reducing blood pressure; the available research is conflicting. Details: A very small clinical study in patients with hypertension shows that taking safflower oil 10 mL twice daily for 6-8 weeks reduces diastolic blood pressure when compared with placebo (72304). However, another small clinical study in patients with mild hypertension shows that taking safflower oil 30 mL daily for 6 weeks does not affect blood pressure when compared to baseline (72268).
• Low birth weight. It is unclear if oral safflower oil is beneficial in infants with low birth weight. Details: A small clinical study in low birth weight infants shows that fortifying formula or breast milk with a specific safflower oil product (Safola, Marico Industries Ltd.) does not improve weight gain or skin thickness when compared with coconut oil or unfortified formula or breast milk (72229).
• Metabolic syndrome. It is unclear if oral safflower oil is beneficial in patients with metabolic syndrome. Details: A small clinical study in patients with metabolic syndrome shows that taking safflower oil 2 grams four times daily for 12 weeks reduces waist circumference by 3.4 cm, systolic blood pressure by 7 mmHg, diastolic blood pressure by 3 mmHg, and fasting blood glucose by 8 mg/dL when compared with placebo. However, body weight, body mass index (BMI), and lipid levels were not affected (108889).
• Obesity. Although there has been interest in using oral safflower oil for obesity, there is insufficient reliable information about the clinical effects of safflower oil for this purpose.
• Myocardial infarction. Intravenous safflower yellow, a component of safflower flower, might improve outcomes when used as an adjunct to conventional therapy for the treatment of acute coronary syndrome (ACS). Details: A meta-analysis of 16 small, low-quality clinical trials in patients with ACS, including myocardial infarction and unstable angina, shows that intravenous administration of safflower yellow 20-40 mL daily for 10-15 days as an adjunct to conventional therapy improves clinical outcomes, electrocardiogram measures, and left ventricular ejection fraction when compared with placebo (108891).
• Phrynoderma. It is unclear if oral safflower oil is beneficial in patients with phrynoderma. Details: A small clinical study in patients with phrynoderma shows that taking 30 mL of safflower oil containing vitamin E 116 mg and linoleic acid 68% daily for more than 8 weeks can partially improve skin dryness and roughness when compared to baseline (72269). The validity of these findings is limited by the lack of a comparator group.
• Scarring. Topical safflower oil has only been evaluated in combination with other ingredients; its effect when used alone is unclear. Details: A small clinical study in patients with non-hypertrophic scars and striae shows that applying an oil containing safflower oil 55.9%, olive oil 42%, grapefruit oil 2%, and tocopherol 0.1% (Kneipp Bio Skin Oil, Kneipp GmbH) to the scars and striae twice daily for 8 weeks improves scores on the Patient Scar Assessment Scale (PSAS) by 20%, compared to a 6% improvement in untreated areas (95938).
• Stroke. Small clinical studies suggest that intravenous safflower yellow, a constituent of safflower flower, as an adjunct to conventional treatments, may improve neurological outcomes post-stroke. Details: A meta-analysis of seven small, low-quality clinical studies in Chinese patients with acute ischemic stroke shows that intravenous administration of safflower yellow 100-150 mg as an adjunct to conventional treatments, starting within 72 hours of stroke onset and continuing once daily for 14 days thereafter, increases the odds of neurological improvement by about 3-fold when compared with conventional treatments alone (94038).
• Unstable angina. Intravenous safflower yellow, a component of safflower flower, might improve outcomes when used as an adjunct to conventional therapy for the treatment of unstable angina. Details: A meta-analysis of seven low-quality clinical studies in Chinese patients with unstable angina shows that intravenous safflower yellow 50-150 mg daily for 14-15 days in addition to conventional treatment modestly improves electrocardiogram (ECG) measures and symptoms of angina when compared with conventional treatment alone (94041). Another meta-analysis of 16 small, low-quality clinical trials in patients with acute coronary syndrome (ACS), including unstable angina and myocardial infarction, shows that intravenous administration of safflower yellow 20-40 mL daily for 10-15 days as an adjunct to conventional therapy improves clinical outcomes, ECG measures, and left ventricular ejection fraction when compared with placebo (108891). More evidence is needed to rate safflower 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).

ANTICOAGULANT/ANTIPLATELET DRUGS Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = B High doses of safflower oil might increase the risk of bleeding when taken with anticoagulant or antiplatelet drugs.  Details Small clinical studies show that taking safflower oil, approximately 55 grams daily for 2-3 weeks, decreases platelet aggregation (72241,72303). However, taking lower doses of safflower oil, such as 5 grams daily for 4 weeks, does not seem to affect platelet function (66267). In one case report, a 74-year-old male stabilized on warfarin developed urinary tract bleeding and an elevated INR after taking a safflower extract 20 grams daily for 14 days (95939).

ANTIDIABETES DRUGS Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = B Theoretically, safflower oil might alter the effects of antidiabetes drugs.  Details Some clinical research shows that taking safflower oil 10 grams daily for 3 weeks can increase fasting blood glucose in patients with type 2 diabetes (13146). However, clinical research in patients with metabolic syndrome with or without impaired glucose tolerance shows that taking safflower oil 8 grams daily for 12 weeks reduces fasting glucose levels by around 8 mg/dL (108889). Some clinical research also shows that taking safflower oil 8 grams daily for 16 weeks does not affect fasting glucose levels in patients with type 2 diabetes (94039).

WARFARIN Interaction Rating = Moderate Be cautious with this combination. Severity = Moderate •  Occurrence = Possible •  Level of Evidence = D Theoretically, safflower oil might increase the risk of bleeding when taken with warfarin.  Details In one case report, a 74-year-old male stabilized on warfarin developed urinary tract bleeding and an elevated INR after taking a safflower extract 20 grams daily for 14 days (95939).
