HelloPharmacist Scorecard of Black Seed Oil by plnt Organics
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: certified organic black cumin seed oil. Black seed has been studied for several health purposes, including skin, respiratory, and metabolic support, and the oil form delivers the plant's compounds in liquid format.
There are no other inactive ingredients listed.
Does it work?
Moderate evidence
The evidence we hold shows black seed is possibly effective for acne, hay fever, asthma, H. pylori infection, and diabetes. That means some clinical research supports it, but we don't have strong proof yet.
If you're taking it for one of these uses, talk with your doctor or pharmacist about whether the data matches what you're hoping for.
How safe is it?
Well-documented data
Black seed oil is generally well tolerated when taken by mouth or applied to skin. The most common side effects reported are constipation, stomach burning or discomfort, nausea, and vomiting.
In one trial, gastrointestinal complaints showed up in about 20% of people taking the oil, though other trials reported these effects rarely. One case of unusually heavy menstrual bleeding was noted in a trial, and one person was hospitalized for severe nausea and vomiting thought to be linked to black seed oil.
The safety data advises against using supplement doses during pregnancy. We don't have enough reliable information about safety during breastfeeding, so talk with your doctor or pharmacist for personalized advice.
Meds to double-check
Moderate interaction found
Before taking this product, double-check if you're on blood thinners or antiplatelet drugs (Moderate risk of bleeding), blood pressure medications (Moderate risk of low pressure), diabetes drugs (Moderate risk of low blood sugar), sedating medications (Moderate risk of extra drowsiness), serotonergic antidepressants (Moderate risk of serotonin-related side effects), immune-suppressing drugs, diuretics, or cyclosporine. Your pharmacist can help you decide if it's safe to combine them.
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 oil may help with acne, hay fever, asthma, and blood sugar control if the evidence holds up for your situation. It's generally well tolerated, but stomach upset can happen.
Because it may lower blood pressure and blood sugar and thin the blood, check your medications first — especially if you're on blood thinners, pressure drugs, or diabetes medications. Talk with your pharmacist before you start.

Black Seed Oil by plnt Organics Drug Interactions
HelloPharmacist Interaction Report
Black Seed Oil by plnt Organics does interact with a number of medication types.
Animal and lab research suggest that black seed may thin the blood, so combining it with blood thinners or antiplatelet drugs (like warfarin or aspirin) could theoretically increase bleeding risk.
Read the full breakdown — every affected drug type, severity by severity
Black seed may also lower blood pressure and blood sugar, which means it could add to the effects of blood pressure medications and diabetes drugs — potentially causing your pressure or sugar to drop too far. It appears to have mild sedative effects in animals, so taking it with sedating drugs might cause extra drowsiness.
Additionally, the ingredient may increase brain serotonin levels, which raises a theoretical risk of serotonin syndrome if you're on serotonergic antidepressants or similar drugs.
Black seed may also interfere with immune-suppressing medications and theoretically reduce cyclosporine levels. It could increase potassium loss if combined with diuretics.
Altogether, these interactions span 905 individual medications.

For each ingredient in Black Seed Oil 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.
certified organic 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.
