I tried Black seed oil from various different sellers and places, here's what I found out. I bought it from a place known as piping rock and the color of it was yellow like olive oil. It tasted like back seed and had a sharp strong flavor. The question would be why would it be yellowish if the seeds are black? That never made sense to me but I assume since it tastes like black seed it must be real. But that is not necessarily the case because they can just add black seeds to oil and probably will likely give the same taste. I used it to try to treat Hodgkin's lymphoma that I had on and off since the age of 14. And I didn't get any improvement with my symptoms. I decided to use that black seed oil from that company because they are cheaper than all the other companies. But that doesn't necessarily mean that it's good or better, It could actually be worse because typically things that are cheaper than everyone else are usually worse than everybody else. But I decided to go to try it for about a year without any improvement with my symptoms and tumors were slowing down and growth, but weren't improving. So I decided to buy a bottle from amazing herbs, I tried it from them for about a year as well and I didn't feel any improvement with my symptoms. The color of the oil was yellowish but not exactly like olive oil a little bit darker. And it also tasted like black seed but a bit stronger than the one from piping rock. So my conclusion now, is that both of them were likely not real black seed oil. So what I advise anyone is to use black seed oil that is black or of dark color and sold in a glass bottle. I also tried it from Egypt from a store that's was a prophetic medicine type store, and the color was also light but not like olive oil, it was of a different color. One of them tasted like it was boiled like a black seed tea. Another tasted bitter and sharp but different from the ones in the US. I also tried a wide range of different remedies like curry powder, green tea, garlic, ginger, carrot juice, wheat grass, royal jelly, and I mixed so many of the remedies together and still no improvement and my dad bought me large gallon of zamzam when we went to mecca and it didn't improve my symptoms. I think this is a punishment from Allah, I have been sick so long, people who were young are now adults and people who were old and now dead. It's a sad problem that I have been put through, and 12 years of my life has just been stoked from me, I nearly cry when I think how much time has past and how much time has been wasted. Please make dua in last third of night that Allah heals me and all Muslims all over the world: https://www.youtube.com/watch?v=TRHBCLdb9xA
