HelloPharmacist Scorecard of Nigella Sativa Powder by Nootropics Depot
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 contains one active ingredient: nigella sativa extract, commonly called black seed. Black seed has been studied for several health areas, including acne, hay fever, asthma, stomach infections, and blood sugar control.
The powder also includes maltodextrin as an inactive ingredient (a binder and filler).
Does it work?
Moderate evidence
Black seed is rated possibly effective for acne, allergic rhinitis (hay fever), asthma, Helicobacter pylori infection (a stomach bacterium), and diabetes, based on the evidence we hold. That means some clinical research supports its use, but the data isn't strong enough yet to call it proven.
If you're considering it for any of these purposes, talk with your doctor about whether it fits your situation.
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 constipation, stomach burning or discomfort, nausea, and vomiting.
A small number of trial participants reported gastrointestinal upset; one person required hospitalization for nausea and vomiting. One clinical trial also documented heavier-than-usual menstrual bleeding.
Larger medicinal doses are less studied long-term, so caution applies if you're considering supplement amounts beyond food-level doses. Pregnancy is rated likely unsafe for supplement doses, so avoid this product if you're pregnant.
For breastfeeding, we don't hold enough safety data, so talk with your doctor or pharmacist before taking it.
Meds to double-check
Moderate interaction found
Before taking this product, talk with your doctor or pharmacist if you take serotonergic drugs (antidepressants, migraine medications), blood pressure medications, blood thinners or antiplatelet drugs, diabetes medications, sedating drugs, diuretics, immune-suppressing drugs, or cyclosporine. Black seed may change how these medications work or raise the risk of side effects.
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 seed may be worth considering if you're interested in its possibly-effective uses—acne, hay fever, asthma, stomach infections, or blood sugar control—and you don't take medications from the types listed above. If you take any blood pressure drugs, blood thinners, diabetes medications, antidepressants, sedating drugs, or immune suppressants, you'll want to clear this with your doctor or pharmacist first.
Pregnant people should avoid it, and breastfeeding parents should check with their healthcare provider.

For each ingredient in Nigella Sativa Powder 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.
Nigella sativa extract
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.
