Photo by Komatsu/E+
Black seed oil, or black cumin seed oil, is extracted from Nigella sativa seeds. It contains compounds that have antioxidant and anti-inflammatory effects in people, and it’s sometimes recommended for pets to support a healthy coat and skin, modulate inflammatory conditions like allergies and joint disease, and help with immune support. However, there is very little direct canine research into black seed oil, and most of what we know comes from human studies, so it’s always a good idea to check with your vet before adding a new supplement to their diet.
Here’s what we know about black seed oil, whether it should be used in dogs, and when to talk to your vet about it.
Key Takeaways
- Black seed oil, extracted from Nigella sativa seeds, has antioxidant and anti-inflammatory effects in people.
- Studies using black seed oil in dogs are limited, so it’s best considered a supportive therapy recommended by your vet.
- Talk with your veterinarian before trying black seed oil, especially if your dog has a medical condition or is on medication.
- Side effects of black seed oil include digestive upset, vomiting and diarrhea, and allergic reactions.
How Does Black Seed Oil Work in Dogs?
Black seed oil is made from Nigella sativa seeds. It’s a rich source of compounds including thymoquinone, which is an antioxidant, and healthy fatty acids. In people, these compounds have been shown to help modulate inflammation and blood sugar, control blood lipids, and other healthful effects.
In dogs, however, there is very little direct research on the effects of black seed oil. Because of its antioxidant properties, some vets recommend it for uses including:
- Coat and skin support
- Reducing symptoms of allergies such as itching
- Supporting healthy joints
These recommendations are based on extrapolating black seed oil’s benefits in humans to dogs, which may not always be accurate.
As a result, it’s best to consider black seed oil a supportive therapy and not a primary treatment for any of the conditions listed above.
Potential Side Effects of Black Seed Oil in Dogs
Black seed oil’s safety profile in dogs is also limited, so potential side effects are not well mapped out. Because supplements can cause problems or interact with other products and medications, it’s best to use caution and consult your veterinarian rather than guessing.
In general, dogs taking black seed oil may experience digestive effects such as vomiting and diarrhea. They may also have an allergic reaction that would cause itchiness and skin issues.
In one canine study in Beagles, black seed oil interacted with medications the dogs were taking for other conditions. If your dog is taking any medications, don’t give them black seed oil without first talking it over with your vet.
How to Give Your Dog Black Seed Oil
Use black seed oil only if your veterinarian thinks it’s appropriate for your dog. There is no standard canine dose, so the safest move is to ask your veterinarian to review the exact product you’re considering and ask them to recommend a safe dose.
If your vet says it’s okay to try black seed oil, choose a product with clear labeling and avoid formulas with ingredients you don’t recognize. Keep the packaging handy in case you ever need to double-check what’s in the bottle.
What to Do If Your Dog Gets Into Black Seed Oil
If your dog gets into a bottle of black seed oil or seems unwell after taking a dose, call your veterinarian, an emergency hospital, or the Pet Poison Helpline (855-764-7661) right away. Have the package or bottle with you so you can relay details about the exact product and ingredients.
