Rainy, I think it's been probably about ten months since I've been taking it. I can't say for sure what it's helped since I'm always trying a lot of different things at once but since I've been taking it, my sleep, pms symptoms, environmental allergies, have all been better. Also a couple of months ago, I had what's called costochondritis. It's really painful inflammation in the chest wall. I started using the blackseed oil externally where the pain was and it started helping immediately. I continued doing that and the pain was gone in a few days.
So I think it's good stuff. It's not been a cure-all for me for sure, since I still have lots of other issues it hasn't seemed to touch. But I'll keep taking it and see what happens.
I wish it didn't lower blood pressure since I already have really low blood pressure, but I haven't really noticed any worsening of symptoms in that way.
