    Hello I heard about the great things this oil does tried it starting with 1/2 teaspoon with food. Had extreme diareah. I quickly cut back to just a few drops. After a couple of days started feeling week then stopped all internal use. Last was 6. Is there any known interaction? Thanks

    • Ed Small says:

      That’s funny, I take a teaspoon three times per day for 3 years now and I have had no ill effects from this oil at all. In fact, my health has improved tremendously. Are you absolutely sure you were taking oil of Nigella Sativa? I can’t imagine why you would react to it negatively. Maybe your body just isn’t made like mine. Some people can’t eat strawberries or tomatoes. While other people have no problem with strawberries or tomatoes. Some people get terrible diarrhea from prune juice, while United States Senator Strom Thurmond drank prune juice every day without any problems. I read it somewhere that he attributed it to one of the causes of his longevity. He lived to the age of 100 years. Perhaps he could have lived to the age of 110 years or more if he had taken Nigella Sativa regularly. You never know. Well, I am going to continue taking my Nigella Sativa Black Caraway seed. I crush the seeds in a coffee grinder and put it in honey. The oil on the market is much too expensive. Good God (as the late great James Brown, godfather of soul would have said), I wouldn’t be able to afford to get a hair cut if I bought the oil on the market. The seeds are much less expensive and they provide much more benefit. I’m sorry for you that you are unable to benefit from the consumption of this wonderful oil, there is really nothing that compares to it. For what were you taking it? Well good luck. I hope it is resolved. Godspeed.

    • Vasilios says:

      Yeah it’s ok to take blackseed oil . Try take them far apart like one in the morning and the other at night that’s what I do and just take a teaspoon full and wash down with water before bed and u will sleep well. . If u start to feel dizzy go to ur doctor coz u mite have to reduce coz the oil helps . I’ve been taking both for months now no issues at all

  2. Marilyn Chappell says:

    I took black seed oil before called Amazing herbs with no side effect, but this time I bought Kalonji oil which i believe is the same thing, from an India store. This one i notice cause me to be dizzy. I cut back on the dosage, but i am wondering if it make a difference on the brand or where the black seed came from. Also this one says 100 % pure oil. The Amazing herb one says Cold pressed oil maybe thats the difference. Does the oil need refrigeration.

  3. Jody Roper says:

    Just took my first Tsp. Of black seed oil and it made me feel like my heart was racing and now I feel strange. I know there are no known side effects, not sure if this is psychological, anyone else feel strange after first starting? I have had the blank seed oil pills with no problems but this was a virgin black seed oil liquid.

    • Garrick says:

      I had the same feeling of racing pulse and indigestion for more than a day with the cold pressed black seed oil-it was the first time I’d taken it (one teaspoon)

    • Vasilios says:

      Do t worry it just gives u a bit of a kick wen u take it coz it’s putting oxygen into your blood and it’s just great for circulation so don’t worry I get same thing doesn’t last long . If ur worried then see ur fix but they don’t know about the great benefits of this oil

    • Michelle says:

      I’ve had no issues with starting mine. You have to be careful where you get the black seed oil from. I was told to make sure I purchased from an authentic Indian store. Not the GNC’s and supplement stores because they still put some extra stuff in it. Even when buying online be careful

    • Matt says:

      I didn’t experience that when started taking it. I do know that a increased heart rate after ingestion can be food allergies or sensitivity.

    • Shalona King says:

      Hey Francis Perera, i was just asking my uncle if the black seed oil can help. If im reading this right did you say it gave you heartburn?

  4. Zulfa Dominick says:

    I also.started using the cold pressed oil and started getting dizzy spells and just feeling weird, like palpitations I’m not sure how to describe it. Like blood pressure is all over. The capsules had no side effects though. Will try reducing to less than I tsp of oil n see if it still happens.

    • Adriel says:

      I felt the same way. I took less than a teaspoon and still got the same bad feeling. The only difference was that it took longer for me to start feeling bad.

  5. Chakra says:

    I have started using this. 5ml of this oil + 5 ml of Olive oil. First two days, only some burping, no other issues. Now getting a slightly sore throat. Thinking of reducingthe dosage.

  6. Randall Edney says:

    Best thing I have ever taken and Im not the pill popling type. All together feel better. More energized and even the libido has gotten stronger at 42.

  7. David Brian says:

    I’m taking “Amazing Herbs Black Seed 100% pure cold-pressed black cumin seed oil” for the first time. (1 tablespoon by mouth) with an apple, mixed nuts and elderberry tea. At first the taste is bland but Then quickly changed to an oily bitter taste. #blackseedoil

  8. Vasilios says:

    I’ve been taking black see oil for a year now at night and I sleep like a baby . Sometimes it give me a mild rush for very short time nothing to worry about it’s great for your health and lowering blood pressure. Don’t take too much coz u will get the runs . Once a day is fine . If u want to lose weight take it in water and honey and cinnamon powder and scull it down . This will make the fat fall off . It’s true .

  9. Graciela says:

    Hello…I am experiencing alot of acne over the top half of my body since i have been taking black seed oil and drinking alkaline water…Could this be a side effect of the black seed oil?

    • Scott says:

      Stop taking alkaline water! You have low stomache acid. Get some HCl and diestive enzymes and changes your diet. Cyt out sugar. Grains. Starches. And raw veggies.

  13. Bless says:

    Am in South Africa, where can I find this black seed oil in South Africa and what kind of black oil do I need to take as there is a variety.

    • Mary says:

      The doctor in Africa that was using Black Seed Oilwas giving 5ml that equals 1 tsp.
      3x a day for 6 weeks. mixed with warm water and honey. the studies showed improved. in fact after treatment showed no present.. the only med used was black seed.. so I would surely check with a doc if you are on other meds. If you buy this be sure it is a trusted brand. it should say Nigella sativa cold pressed. There was stomach upset reported with this dose. If you have any known allergies you should question the seller for info.

  14. Kathleen says:

    I was taking black seed oil a teaspoon daily and started having my tongue get very dry. Stopped taking it and the dry tongue stopped within a few days. But I don’t know if this was an interaction with other.

  15. Pamela C Washington says:

    Saturday was a Bad day with the black seed oil. Sunday was a Good day! Felt good. Voice came back. I could sing high notes. Lots of energy! I know about all the benefits but worried about trying to swallow it. Got a bit of a sore throat last night… Are the pills any good?
    Also, if I want to delete a previous post, how do I do that? Don’t want to scare anyone away from trying it.

    Is this any danger to damaged my liver .for warming the black cumin oil

  19. TERRY L KELLY says:

    I started talking the Kalonji Oil for over a month ago and I like it. Only problem I am having trouble with is my face feels like it’s breaking out internally every few days and I have a small rash under my right arm. I follow the oil with organic honey every time I take it. I am eating less sweets but is that fighting against my body? I want to make sure I am doing all I can.

  20. Ali says:

    How does blackseed effect menstration, I’ve been irregular for the two months of taking it. I feel great otherwise but this is a bit concerning as I have prolonged pms and cramps but no actual cycle.

  21. Ursula Gehler says:

    I started using Black Seed Oil because a friend told me it might help. I was told that I practically “sailed through” the treatment which I had once a week for 5 months. I did not have much pain. My hair grew back and is very thick. I definitely keep taking Black Seed Oil for the rest of my life. I am 70 years old. Great productu

  23. Diane Myers says:

    I have been taking black seed oil, one teaspoon a day fo approximately 2 months. Recently, I’ve noticed an increase in anxiety, but less headaches and nausea. Thank you.

  24. Kimlee says:

    My first three days I received a headache and my throat was sore and I had a bit of anxiety bu know nothing but I am losing weight and I feel better o believe the side effects is the product getting all the garbage out of you. You know how when you detox at first you get sick then you feel better. I take the pill form I believe liquid is more potent and circulates through your system quicker try taking half the dosage and document how you feel

  25. Kim says:

    I have been taking a teaspoon twice a day for a few months to boost my immune system and it seems to be working!!! I take a little more throughout the day and my body will start to feel really tired and achy but I won’t get sick! After about a day I’ll feel fine! I assume the tired achy feeling is the oil helping my body. But I have a friend who had to stop taking it because it made her feel hot, itchy and irritable so each person must react differently.
