What is Black Seed Oil?

Black seed is a plant that has been used for medicinal purposes for over 2,000 years. Black seed has been used for a wide variety of ailments, including toothaches, headaches, conjunctivitis, and parasites. It has many names, being called Black Cumin, Black Caraway, Black Sesame, Onion seed, and Roman coriander. These cumin seeds are typically compressed for their oil and are said to have a ton of great health benefits such as anti-inflammatory, anti-bacterial, anti-cancer, anti-fungal, and anti-oxidant. Black seed oil is also a great source of fatty acids, which may even help weight-loss. We’re quite impressed with the information available on Black Seed Oil and the scientific studies supporting it, but we’ll circle back to that…

What are Black Seed Oil Side Effects?

The first problem noticed related to Black Seed Oil side effects. “We did some digging on this herb, and we can honestly say that we were shocked at the adverse side effects it can produce,” said our Research Editor.

“Sent my pressure through the ROOF!!” said one user. According to WebMD, “Black seed might slow blood clotting and increase the risk of bleeding. In theory, the black seed might make bleeding disorders worse.”

Don’t be scared by the Black Seed Oil side effects though, there are plenty of people who take the oil and plenty of positive and rather compelling testimonials. “I will continue to keep a bottle of this oil on hand and have told others to read up on all the ailments it’s reported to help. I can only testify to it ridding my daughter of hives, but would recommend everyone learn more about this product.”

What is Black Seed Oil Good For?

The second problem with Black Seed Oil was authenticity. You never know what you are getting when there are so many distributors selling this oil. We found an outpouring of customer complaints who just were not satisfied with their order, from receiving the wrong type of oil to getting a less pure version than they had hoped for.

“DO NOT BUY!! In comparison to the previous batches is vastly less concentrated than the previous batches,” wrote one user of the herb.

Another user added, “This is NOT true potent Black seed oil. Do not buy this oil. I have been taking it since the day I purchased it, in spite of the fact that it is weak in color and taste, and it tasted like Olive oil infused with pencil shavings. It should be way stronger. It is NOT affective.”

There are plenty of distributors selling authentic black seed oil. So, all we’re saying is do your research before purchasing.

The Science Supporting Black Seed Oil Benefits

As said before, there is certainly scientific evidence on this ingredient. Black seed oil contains thymohydroquinone and thymoquinone which are responsible for the herb’s health benefits. One online study stated that “results indicate that THQ (thymohydroquinone and thymoquinone) antitumor activity may be improved with a further dose increase of the investigated substance.”

Another study highlighted that, “Thymoquinone was the best antifungal compound against all of the tested dermatophytes and yeasts, followed by thymohydroquinone and thymol respectively. Thymol was the best antifungal against molds followed by TQ and THQ respectively.” There is research backing this ingredient’s beneficial health properties, unfortunately, there is nothing regarding its weight-loss effects.

What Users Are Saying

“”I am using this product daily and am having better results in my health and well-being. I was able to clear up thrush in my mouth and bring the pinkness back to my tongue. I use this with other herbal products to lower my blood sugar!””

“”The taste isn’t as bad as I imagined. Will purchase again.””

“”I feel no change in me.””

Product Features

Black Seed Oil is a rich source of essentially fatty acids, which have a variety of health benefits, and may assist the body in transporting fat out of the body. Too many fatty acids though, can lead to weight gain, whether they are good or bad fats or not. Traditionally, black seed oil is used to treat: headaches, toothaches, congestion, hair and skin issues, diabetes, allergies, and digestive/gastrointestinal issues. Having said this, there is not much, if any of a weight loss benefit to this option, other than that it may be able to improve your digestion, which will make your body more efficient at using nutrients and removing waste. It can help stop nausea and upset stomach, as well as diarrhea.


  • Black Seed Oil has many health benefits.
  • This product is completely natural.


  • Black Seed Oil does not really have a direct link to weight loss.
  • Since there are so many different manufacturers of this product, you never know if two are really the same or not.
  • There are no free trials of this product.
  • Though there are customer testimonials, none of them support the use of this product as a weight loss aid.
  • This is a costly investment, at nearly $20 for only 8 ounces of the oil.


Black Seed Oil is probably something worth having in your medicine cabinet, whether you are trying to lose weight or not. Even though it is not likely to help you shed more fat or suppress your appetite to support your diet and exercise efforts, it could help you with a number of other health issues you or anyone else in your family may experience at any given moment. In terms of weight loss however, we recommend you keep looking for a clinically proven safe and effective appetite suppressant or fat burner and use it with a balanced diet and regular exercise program.

8 Black Seed Oil Reviews

  • Shawn T (Verified User)

    I’ve recently purchased black seed oil and I am hopeful to see some health benefits, however it is one of the foulest, most gag-inducing substances that I’ve ever tried to consume. I’m currently only taking 1 tsp every other day due to the trauma of literally throwing it up the first time. Mixing it with honey, apple cider vinegar and some warm water helps but it is still God-awful. I can see how it would be helpful to losing weight if you take it before eating. The taste lingers…. Good luck
