    We strive to make sure our Black Cumin Seed Oil is the highest quality oil available. We are so confident about our product, we gladly offer a 14-day money-back guarantee.

    Using only the highest quality Black Seeds from around the world, we’re able to produce 100% unrefined virgin Black Cumin Seed Oil.

    Our Double Strength Black Seed oils are manufactured using a slow, cold-pressed method which helps preserve the volatile components found in the oil. Documented research has revealed that many of the potent activity found in Black Seed Oil resides in its volatile oil.

    We press our oils at the slowest speed possible, to ensure we have the finest quality cold-pressed oil available on the market.

    Our Packaging

    All our Black Cumin Seed oils are supplied in special UV protected amber glass bottles. 

    Glass does not leach and amber glass helps to keep the temperature down and UV light out. It is the best choice to protect and preserve the healing properties of the oil.

    • All our Black Seed oil bottles come fitted with tamper-proof seals for peace of mind.

      We package all orders securely using extra care to individually pack our bottles for increased protection.

      Very happy with the double strength BSO

      I suffer with both fibromyalgia and Neuroinflammation. I find the Black Seed Oil very effective at reducing inflammation, which decreases pain from the fibro and cognitive iissues from Neuroinflammation.

      I find it easiest to take by putting the dose directly under my tongue and washing it down with a glass of water. Barely any taste that way.


      I've really enjoyed this product, seems to be working great on inflammation.


      I found this to be even better than I thought.

      Black seed oil

      A bit too early to tell but I am starting to feel a bit better after a long bout with chest infection . I am not suffering as much from aching feet as well . The transaction and receiving product went smoothly .

      How to improve your health

      Since taking black seed oil I have had more control of my blood sugar levels, most important for a diabetic. I have suffered chronic back pain for years and black seed has enabled me to halve my painkillers to this point in time and I believe I will be able to cut them a lot more

      I bought this mainly for the capsules, for pain in my back, knee and elbow. Im almost through the first bottle. Its difficult to say if it's made a difference, but giving the benefit of the doubt, I've purchased another two bottles of the DS capsules to give it a fair go. I will say that it has DEFINITELY helped with my sinuses/ sneezing.....that is without any doubt! I take 2 morning and 2 at night. I did use the oil topically on a small rash I had, and it was gone in a couple of days!

      So far so good

      I just started the first bottle so I can't give much of a feedback. I hope that in a month or so I can give better one. Thanks Aleks.

      Jarrah Honey

      Reading the description on your sight for the Jarrah Honey, I feel I will get many benefits from it. Have not opened the jar as yet, but soon will.

      Very pleased with the items purchased will be ordering more in the future. .

      Highly recommend! a Must have boost for the immune system.

      My friend got me onto this as she bought it for her dad who had been diagnosed with a tumour. Within two weeks he was out of hospital and feeling a lot better. We figured if it can help with cancer it must be good for you so ordered some. We take it once or twice a week, normally when we're just feeling a little under the weather. It makes you feel better within an hour and neither of us haven't been sick since we started taking it. The capsules are better than the oil!
