HelloPharmacist Scorecard of Black Cumin Seed by Maxi Health
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 3 active ingredients: polyunsaturated fat, monounsaturated fat, and black cumin seed oil. Black cumin seed oil is the main active component and contains compounds like thymoquinone, which research suggests may support immune function and have mild effects on blood sugar and blood pressure.
The product also includes inactive ingredients — cellulose (a binder), silicon dioxide, and D-alpha-tocopheryl acetate (a form of vitamin E) — used to make and stabilize the capsule.
Does it work?
Moderate evidence
The evidence for black cumin seed is rated "possibly effective" for a number of conditions. Research suggests it may help with acne, hay fever (allergic rhinitis), asthma, helicobacter pylori infection, and blood sugar control in diabetes.
That said, "possibly effective" means the research is promising but not yet conclusive — more studies are needed to confirm how well it works and in whom.
How safe is it?
Well-documented data
Orally, black cumin seed is generally well tolerated in food amounts, but long-term safety at higher supplement doses isn't well studied. The most common side effects reported are constipation, stomach burning or discomfort, nausea, and vomiting.
One trial reported relatively severe menstrual bleeding in a patient taking black seed, and in another trial, about 20% of people taking black seed oil had gastrointestinal complaints; one patient was hospitalized for nausea and vomiting. The safety data advises against supplement doses in pregnancy, and there isn't enough reliable information about safety while breastfeeding — talk with your pharmacist or doctor before using it if you're pregnant or nursing.
Meds to double-check
Moderate interaction found
Before taking this product, check with your pharmacist if you use blood thinners or antiplatelet drugs (highest concern for bleeding), sedatives or CNS depressants, serotonergic antidepressants, blood pressure medications, diabetes drugs, diuretics, immunosuppressants, or cyclosporine. All of these have documented Moderate-severity interactions with black seed.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.
Black cumin seed may help with hay fever, asthma, acne, and blood sugar control based on current research, but the evidence is still developing. It's a bigger concern if you take blood thinners, blood pressure meds, diabetes drugs, or certain psychiatric medications — you'll need to check those carefully before starting.
Talk to your pharmacist before you add this to your routine, especially if you're on any regular prescriptions.

Black Cumin Seed by Maxi Health Drug Interactions
HelloPharmacist Interaction Report
Maxi Health Black Cumin Seed contains black cumin seed oil, which has documented interactions with several common medication types.
The most serious concern is with blood thinners and antiplatelet drugs (like warfarin or aspirin) — black seed may increase bleeding risk by thinning your blood further, potentially raising the chance of serious bleeding.
Read the full breakdown — every affected drug type, severity by severity
You'll also want to check if you take sedatives or other CNS depressants, serotonergic antidepressants (like sertraline or fluoxetine), blood pressure medications, diabetes drugs, diuretics, or immunosuppressants — black seed may add to their effects or interfere with how they work. There's also a specific concern with the immunosuppressant cyclosporine; animal data suggest black seed might lower its blood levels and reduce its effectiveness.
The product contains polyunsaturated fat and monounsaturated fat as well, but we don't have interaction data for those ingredients. Altogether, these interactions span 905 individual medications.

For each ingredient in Black Cumin Seed 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.
