HelloPharmacist Scorecard of Black Seed Oil Cardio-Plus by North American Herb & Spice
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 has 4 active ingredients: black cumin seed oil (the main one, also called black seed), thymoquinone (a constituent of black seed), and omega-6 and omega-9 fatty acids. Black seed is the traditional medicinal component; the omegas support its cardiovascular positioning.
The inactive ingredients — extra virgin black cumin seed oil, pomegranate syrup, and muscadine — are there as a base, sweetener, and supporting botanical.
Does it work?
Moderate evidence
Black seed has evidence backing it for acne, hay fever, asthma, Helicobacter pylori infection, and blood sugar control — all rated possibly effective in our data. That means there's some research supporting benefit, but it's not yet conclusive.
The product's 'Cardio-Plus' name suggests heart health, but effectiveness ratings specific to cardiovascular function aren't on file for us. If heart support is why you're considering this, ask your pharmacist what the research actually shows.
How safe is it?
Well-documented data
Black seed is generally well tolerated when taken by mouth or applied to skin. The most common side effects are gastrointestinal — constipation, stomach burning, nausea, and vomiting.
In clinical trials, about one in five people reported some stomach upset, though usually mild. One case of menstrual bleeding occurred in a trial, and one person needed hospitalization for severe nausea and vomiting.
The safety notes flag that higher supplement doses haven't been studied long-term, and that medicinal amounts are likely unsafe in pregnancy — the data rates it likely unsafe, so avoid supplement doses if you're pregnant. There isn't enough safety information for breastfeeding, so talk to your pharmacist or doctor before using it if you're nursing.
Meds to double-check
Moderate interaction found
Before taking this product, double-check with your pharmacist if you're on any CNS depressants (sleep aids, sedatives, anxiety drugs), serotonergic drugs (antidepressants, certain migraine or pain medications), blood pressure medications, blood thinners, diabetes medications, water pills (diuretics), drugs that suppress your immune system, or cyclosporine. All are documented as potentially affected.
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.
Black seed has research backing several health uses and is usually well tolerated, but it does interact with a significant number of medications — especially blood thinners, blood pressure drugs, diabetes drugs, and sedatives. If you take any prescription medications, check them against the tool on this page first.
Pregnant women should avoid it. It's a good fit for someone with no drug interactions looking for support with acne, allergies, asthma, or blood sugar, but always verify with your pharmacist.

Black Seed Oil Cardio-Plus by North American Herb & Spice Drug Interactions
HelloPharmacist Interaction Report
Black Seed Oil Cardio-Plus from North American Herb & Spice contains black cumin seed oil, which interacts with a number of medications.
The most serious documented concerns involve CNS depressants (drugs that make you drowsy or sedated) — animal research suggests black seed itself may have sedative properties, so taking it with these drugs could intensify drowsiness or sedation.
Read the full breakdown — every affected drug type, severity by severity
Black seed also affects serotonergic drugs (antidepressants and certain pain or migraine medications), antihypertensive drugs (blood pressure medications), blood thinners (anticoagulants and antiplatelet drugs), diabetes medications, diuretics (water pills), immunosuppressants, and cyclosporine — a calcineurin inhibitor used after transplant. In each case, the concern is moderate: the supplement may intensify the drug's effect or, in the case of blood thinners and diuretics, may increase risks of bleeding or potassium loss.
Black seed also lowers blood pressure modestly in research, so combining it with blood pressure medications needs watching.
We could not check the interaction data for thymoquinone, omega-6, and omega-9 — those ingredients weren't held in our monographs. Before you start this product, please check your exact medications using the search tool on this page.

For each ingredient in Black Seed Oil Cardio-Plus 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.
