Potent and Pure — You Can Feel the Difference
Flavor Name: Extra Strong, Size: 3.4 Fl Oz
This black seed oil is definitely strong — you can tell it’s pure and freshly cold-pressed from the first taste. The flavor is bold but clean, exactly what you’d expect from a high-quality oil. I appreciate that it’s ethically sourced and bottled in glass instead of plastic, which helps preserve its freshness.
I’ve noticed a difference in overall energy and digestion after adding it to my daily routine. It’s not the easiest oil to take straight, but it’s worth it for the results. Solid value for the quality and strength.
Black seed oil has become one of my go-to oils for skincare. It absorbs quickly without leaving a greasy film and helps calm irritation, dryness, and redness almost instantly. I like to mix a few drops with my regular moisturizer or apply it directly at night — it leaves my skin soft, hydrated, and with a healthy glow by morning. The natural antioxidants and fatty acids make it great for restoring balance, especially if you deal with uneven tone or occasional breakouts. It’s a strong oil, so a little goes a long way, but the results are worth it — smoother, clearer, and healthier-looking skin.

Said to have healing qualities - high quality and pure in nice package - but could use a drip spout
Flavor Name: Extra Strong, Size: 3.4 Fl Oz
Super high quality - pure - blackseed oil. If I were to change anything, I would want it in a container that I could control the flow out of. That said - I use this on my knee (which is giving me some trouble these days) - hearing from a co-worker that in another country, this oil used with some prayers, is known for healing. I can't vouch for that - but I do use it as a matter of hoping the oil might get into my joints and help my knee hurt a little less some days. The packaging is great, and I love the bottle. I would just encourage them to put a 'drip spout' on the bottle - because if you know anything about oil, it finds it's way down the sides of the bottle if you aren't careful. Easy clean up since it's a natural substance though. It does have an interesting 'gun oil' smell - to me. It's not bad in any way. And it also seems to absorb quickly into my skin. It is on the brown-ish side, and if you rub your skin against material before it dries - well just remember - it's 'oil'...and may discolor what you touch.

Best quality I've found on Amazon yet
Flavor Name: Extra Strong, Size: 3.4 Fl Oz
I've tried several different brands of black seed oil on here and so far this one seems like the best quality yet. It makes me feel really great when I take it regularly. I try to find one's with 2% tq or higher and this one has it. I see reviews where people won't take black seed oil bc of the taste and that it upsets their stomach and I concur on both, however, there are ways around both. To take, I put a teaspoon under my tongue and take a swig of water after to wash it down, then a few more swigs to get it all down and no taste left in the mouth. I never taste it that way. You also should take it after a meal, not on an empty stomach. It makes me very queasy and burpy if I don't eat first. So I make sure to take it after breakfast and no stomach issues at all! Highly recommend.
