Black Cumin Oil is one of my favorite supplements.  It seems to help many people with a diverse array of issues.




Nigella sativa, commonly known as Black Cumin, Black Seed, or Black Cumin Seed is native to South Asia (R).

  • Hosanna

    I’m surprised there isn’t anything in this post referencing methylation and this oil.

  • Glen

    Black Seed Oil and Black Cumin Oil are derived from two totally different plants: Black Cumin from the Fennel Flower and Black Seed from Nigella Sativa. The health benefits are different as well. This article is very confusing as the narrative flips between Black Seed Oil and Black Cumin Oil and attributes the bennefits of one to the other. Also, the authors product of choice is Black Cumin Oil and not Black Seed Oil.

  • andreia

    Hello. I didn´t understand the post below (the link you provided still states that Nigella Sativa and Black Cumin are the same thing)

    This is for the gentlemen ED that posted on 5/9/18 regarding the confusion between Nigella Sativa and Black Cumin….a few years we started realizing the difference and that’s been corrected…we are not as dumb as he thinks we are (thankfully) I think this article will enlighten him a bit.

  • andreia

    Do you know if Nigella Sativa Oil is high in phenols or salicylates? I am afraid to take it as I am salicylate intolerant.

  • Veronica. Whiteside

    Can anyone tell me if it helps with chronic Rhumatoid Arthritis / Osteoarthritis and Fybromyaligea

  • Barbara

    This is for the gentlemen ED that posted on 5/9/18 regarding the confusion between Nigella Sativa and Black Cumin….a few years we started realizing the difference and that’s been corrected…we are not as dumb as he thinks we are (thankfully) I think this article will enlighten him a bit.

  • Bledar

    I have used for 2 years and has saved me from radiation and cancer.

  • Ed

    Your article is a bit flawed. The picture at the top is not black cumin. It is Kalonji, or Nigella Sativa. Nigella Sativa and Black cumin aren’t the same thing. In fact, Nigella isn’t a cumin in the first place.

    With regards to this, the internet is full of wrong information, which i put down to white people not really knowing these things, but seeking to be an authority on everything without checking with the relevant experts, i.e. Indians.

    So many talk about the benefits of black cumin, while this is actually true of nigella and not black cumin. To us south indians, who use this in our cooking, black cumin is know as Kali Jeera.

  • eb11

    I’m thinking if combined with serrapeptase extract and/or corn silk tea, it would be very effective for circulation problems and good for the whole cardiovascular system. Any thoughts?!

  • fernella

    I Believe for this or any other oil and or herbs to fonction as they should, a complete diet and even life style is needed. As good as the oils and or herbs are, they wont work if we continue to poison our bodies with all the chemicals and poor eating habits……..

  • Jenny

    Black seed, which the sought after oil is made from, is actually nigella sativa and not related to cumin and Black seed is not a cumin. Black seed oil, nigella sativa, comes from the beautiful Love-in Mist flower.

  • Sujatha

    Black cumin seed is highly beneficial when it is taken with ajwain and fenugreek seed powder. This combination has reducef palpitation problem (increased heart beat).Now the heart beat is normal.

  • Cindy Post

    There is nothing here that tells me if this has blood thinner properties. Please let me know

  • CDix

    Yes! I couldn’t figure out which supplement it was that made my hot flashes and night sweats disappear because I started taking so many things all at the same time. Then I ran out of my black cumin seed for a week. Now I KNOW that it was the tsp of black seed I take in my (Nutribullet – so they are ground up) green drink twice a day. 57 years old, one year into menopause and ZERO hot flashes when on it. This stuff is amazing, and I’m not ever going to run out of it again! Lol

  • T p payne

    My wife has a circulation problem which is causing ulcers on her legs with severe pain. Although these are being treated with antiseptic fluid and crepe bandages as soon as she lies down the pain gets unbearable. Would rubbing black cummin oil be on the ulcers be advisable. She has not slept in her bed for 6 weeks and sleeps in her chair,when the pain lessens.


    21 seeds is equivalent for 1 teaspoon twice per day? Thanks

  • Lang

    Black Cumin Seed Oil is listed under “Supplements to Inhibit Th17/IL-17”. I tried for Grave’s Disease. It really cranked up the thyroid levels! (The opposite of what I needed) I believe this contains mega doses of iodine. And Iodine is listed under “Factors That Increase Th17 Immunity that You Should Avoid”. So these are conflicting.

  • Carol

    How do you make oil from the seeds. I have a one lb bag of seeds.

  • Paula

    Can you take the black cumin essential oil as opposed to the capsules or the oil in the article?

    1. Helen

      Hi Paula, there are many different oils available. 1 2

  • Rob

    The science coming out on blackseed cumin oil and its particular bioactive constituents is really interesting. That said, speaking from personal experience as someone who suffers from a Th1-mediated disease and has tried a range of brands, including Amazing Herbs, I haven’t found the oil to be a therapeutic ‘panacea’. Unfortunately, it seems anything that’s described as an ‘immune modulator’ doesn’t work for me. Don’t know exactly why? Perhaps, if the immune system is fundamentally dysfunctional and overreacting to a pathogen or healthy cells for whatever reason then immune modulators only serve to potentiate this dysfunction??

    Thankfully, I will add that I’ve had superb success with Th1 inhibitors/Th2 stimulants 🙂

  • Jade

    When is the best time to take this oil?with food or in an empty stomach?thank you

  • Ona

    I have struggled with numerous health issues the past few years, and one of them was a total loss of appetite. I was skin and bones. I have tried so many medicines, natural and Rx that did little to nothing for me. I have been munching black cumin seeds for a couple weeks and I have enjoyed three food items in the last three days! That may sound crazy, but I’m so grateful I could cry! I would wager the seeds will help you, don’t be afraid to try.

  • Servant of Allah

    For those underweight people like me (used to): read their two posts below:

Fast forward now after consuming black seed oil and NAD+ supplements along with light exercise and a better diet, i gained weight and loving it. I felt like a skeleton when i was admitted after the acidosis episode lol. Really thin back then. Now i feel so much better and healthier. Please do try the oil. Highly recommended

    Very interesting article,cumin seeds are always beneficial but the above tips gives more ideas to use these black cumin seeds.

  • maryjane

    It cures hot flashes,. I wasn’t taking it for hot flashes initially, I was taking it for allergies. But the hot flashes were just starting at the same time I began using BSO, I had prescriptions for two different treatment options but never got them filled because the hot flashes became milder and less frequent and then they stopped. I didn’t know it was BSO positively until I stopped taking it when I did a 10 day water fast. I didn’t restart it and within in 3-4 weeks the hot flashes were back and much stronger. So I’ve been taking it again for 4 weeks now and once again they slowly and steadily went away. I think every woman should try BSO before taking hormones for hot flashes. I saved over $200.00 a month (with insurance).

  • Paul

    Under antioxidant activity you wrote: “Reduced enzymes like Superoxide dismutase (SOD), Catalase and Gluthathione peroxidase (R).” Isn’t that exactly the opposite of what you want? I thought it was better to increase those three. the reference doesn’t seem to have anything to do with these three. Is this in error?

    1. Nattha Wannissorn

      I just corrected it and found the right reference. Thanks for this.

  • kathi

    what is the dosage recommendation for a child (10 yo; 55lbs). Can I assume the calculation based on what you wrote of 150b person 2tsp and divide accordingly, basically 1/3 of that dose? thanks!

  • Marina

      I have been giving Blackseed to my daughter every day. she used to get fungus on her tongue and she’s not getting that anymore.

    2. Alex B

      why is that?

  • Mark

    Should I take it with fish oil? Or other fats to enhance its absorption? Aren’t you concerned about the omega 6 content?

    1. Shan

      Black seeds or oil if taken with pure organic honey should also maximize the healing effect of this herb oil or seeds.

  • andrewh

    what is the basis for the 25g is toxic to humans claim. I’ve taken up to 35g in one day and have been fine. had decent effects at that dosage.

  • pamojja

    Thanks for the write up. I got a little confused about the different dosage recommendations. Here I read: 1 tsp (5ml) 2x daily for a 150 pound person. In the fatigue post: 1 tbsp (7.5ml) Black Cumin Seed Oil in the afternoon is recommended. Guess it doesn’t make much difference since both is still far from the allegedly toxic 25 g/d. But any specific reason for the afternoon recommendation?

    1. Joseph M. Cohen

      General vs specific.

      1 tsp is more cautious.

  • sam
