HelloPharmacist Scorecard of Black Seed Oil Cardio-POWER by Physician's Strength
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
Black Seed Oil Cardio-POWER contains 4 active ingredients. The main one is black cumin (seed) oil—a traditional extract rich in compounds like thymoquinone that give it its active properties.
The other three actives are thymoquinone (a key component of black seed), omega-6, and omega-9 fatty acids. The product also contains inactive ingredients: extra virgin black cumin seed oil (cold-pressed), pomegranate syrup, and muscadine skin extract, which serve as fillers and for flavoring.
Does it work?
Moderate evidence
Black seed shows possibly effective evidence for several conditions in our data: acne, hay fever (allergic rhinitis), asthma, helicobacter pylori infection (a stomach bacterium), and diabetes. This means some clinical research supports its use, but the evidence isn't conclusive yet.
If you're considering this product for one of those reasons, talk with your pharmacist about what the research actually shows and whether it's right for your situation.
How safe is it?
Well-documented data
Orally, black seed is generally well tolerated. The most common side effects are gastrointestinal—constipation, nausea, vomiting, gastric burning, and discomfort—affecting roughly one in five people in one trial.
One patient was hospitalized for severe nausea and vomiting, and one trial reported unusually heavy menstrual bleeding. Small food amounts are considered likely safe, but higher supplement doses haven't been studied long-term.
Pregnancy is a concern: larger medicinal amounts are not considered safe in pregnancy, so you should avoid supplement doses if you're pregnant or trying to conceive. There isn't enough reliable safety information for breastfeeding, so talk with your doctor or pharmacist for personalized advice if you're nursing.
Meds to double-check
Moderate interaction found
Before you start, double-check your medications if you take blood thinners like warfarin or aspirin (Moderate), blood pressure lowering drugs (Moderate), diabetes medications (Moderate), antidepressants or migraine drugs that boost serotonin (Moderate), sedating medications (Moderate), water pills or diuretics (Moderate), immune-suppressing drugs like cyclosporine (Moderate), or other immunosuppressants (Moderate). No interactions are documented for thymoquinone, omega-6, or omega-9 since we could not check those ingredients.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
This product may help with acne, asthma, hay fever, stomach infections, or blood sugar—though the evidence is still developing. It's not for you if you take blood thinners, blood pressure medications, diabetes drugs, or immune-suppressing medications without checking first.
Avoid it in pregnancy. Talk to your pharmacist about whether it fits your health picture and your current medications.

Black Seed Oil Cardio-POWER by Physician's Strength Drug Interactions
HelloPharmacist Interaction Report
Black Seed Oil Cardio-POWER by Physician's Strength does interact with a number of medications, mainly because of its black cumin seed oil content.
The most serious category is blood thinners (anticoagulant and antiplatelet drugs)—black seed may increase bleeding risk by inhibiting clotting and platelet function, so if you take warfarin, aspirin, or similar medications, you'll want to check with us before starting this product.
Read the full breakdown — every affected drug type, severity by severity
Black seed also interacts with drugs that lower blood pressure (antihypertensives), sedating medications (CNS depressants), serotonin-boosting antidepressants and migraine drugs (serotonergic drugs), blood sugar medications (antidiabetes drugs), water pills (diuretics), immune-suppressing medications (immunosuppressants), and cyclosporine (an immunosuppressant used after transplants). All of these carry Moderate severity.
The blood pressure and blood sugar effects are particularly noteworthy: black seed can lower both on its own, so combining it with your medications could push them too low.
We were unable to check thymoquinone, omega-6, and omega-9 for interactions—we hold no interaction data for those ingredients. Altogether, these interactions span 905 individual medications.

For each ingredient in Black Seed Oil Cardio-POWER 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.
Black Cumin (seed) oil
Anticoagulant/Antiplatelet Drugs
Theoretically, black seed may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
In vitro and animal research suggests that black seed extract can inhibit platelet aggregation and clotting, and increase bleeding time. In addition, decreased platelet counts have occurred in a human case report and in animal research.
Antidiabetes Drugs
Theoretically, taking black seed with antidiabetes drugs might increase the risk of hypoglycemia.
Some clinical research and numerous animal studies suggest that black seed, especially its constituent thymoquinone, can have hypoglycemic effects.
Antihypertensive Drugs
Theoretically, taking black seed with antihypertensive drugs might increase the risk of hypotension.
Clinical research suggests that black seed powder and oil might reduce blood pressure by 2-3 mmHg. In animal research, black seed modestly reduces blood pressure and concomitant use of black seed and amlodipine (Norvasc) or metoprolol (Lopressor) increased the blood pressure lowering effects of these drugs.
Clopidogrel (Plavix)
Theoretically, black seed may increase the risk of bleeding if used with clopidogrel.
Animal research shows that taking black seed extract daily for 2 weeks prior to a single dose of clopidogrel increases maximum concentrations of clopidogrel by approximately 31% and modestly decreases oral clearance. Furthermore, bleeding time was increased by 12%. This has not been shown in humans.
Cns Depressants
Theoretically, concomitant use with drugs that have sedative properties may cause additive effects.
Animal research suggests that black seed may have CNS depressant effects.
Cyclosporine (Neoral, Sandimmune)
Theoretically taking black seed might reduce the levels and clinical effects of cyclosporine.
In animal research, black seed extract decreased the maximal levels of cyclosporine in the blood by 35.5%. This has not been shown in humans.
Cytochrome P450 2C9 (Cyp2C9) Substrates
Theoretically, black seed might increase levels of drugs metabolized by CYP2C9.
In vitro research suggests that thymoquinone, a constituent of black seed, can decrease the metabolism of phenytoin by a mechanism possibly related to the inhibition of CYP2C9. The effect of black seed on CYP2C9 is unclear. This has not been shown in humans.
Diuretic Drugs
Theoretically, taking black seed with diuretic drugs might increase potassium loss and the risk of hypokalemia.
Black seed extract has shown diuretic effects in animals, which could theoretically increase potassium loss. This has not been shown in humans.
Immunosuppressants
Theoretically, black seed might interfere with immunosuppressive therapy.
Animal and in vitro studies suggest that black seed might stimulate immune function. However, other animal studies suggest that black seed may suppress immune function.
Phenytoin (Dilantin)
Theoretically, black seed might increase or decrease levels and effects of phenytoin.
In vitro research suggests that thymoquinone, a constituent of black seed, can decrease the metabolism of phenytoin. This effect may be due to inhibition of cytochrome P450 2C9 (CYP2C9). However, animal research shows that black seed decreases the maximum concentration of and total systemic exposure to phenytoin by 57% and 87%, respectively. This seems to be related to increased clearance and steady state volume of distribution. This interaction has not been shown in humans.
Serotonergic Drugs
Theoretically, combining serotonergic drugs with black seed might increase the risk of serotonergic side effects, including serotonin syndrome and cerebral vasoconstrictive disorders.
Animal research suggests that black seed can increase brain serotonin levels. In one case report, a 35-year-old man undergoing endoscopic surgery experienced immediate postoperative serotonin syndrome that was likely associated with the use of black seed oil 600 mg daily starting 4 days before surgery, and precipitated by the use of serotonergic pain medications, including fentanyl and oxycodone. Monitor patients for signs of serotonin syndrome and other serotonergic side effects if using black seed with serotonergic drugs.
Sildenafil (Viagra)
Theoretically, black seed might reduce plasma levels and the therapeutic effects of sildenafil.
Animal research shows that black seed reduces the total systemic exposure to sildenafil by 43%. So far, this interaction has not been reported in humans.
Warfarin (Coumadin)
Theoretically, black seed might increase levels of warfarin and increase the risk of bleeding.
In vitro research suggests that thymoquinone, a constituent of black seed, can decrease the metabolism of warfarin. This effect may be due to inhibition of cytochrome P450 2C9 (CYP2C9). The effect of black seed on warfarin metabolism is unclear. This has not been shown in humans.
Prednisolone
Theoretically black seed might reduce plasma levels and therapeutic effects of prednisolone.
In animal research, oral administration of a single dose of black seed oil 15 minutes prior to oral prednisolone decreases the prednisolone maximum plasma concentration by 65% and area under the curve by 25%. This has not been shown in humans.
