Another recent human study also using Nigella Sativa, found that it is also capable of lowering high blood pressure. That's quite a combination!

Nigella Sativa (NS) is available at most on line vitamin suppliers as well as local health food stores and is reasonably priced as supplements go at the tested dosages in these two studies. NS has shown other potential health benefits and the number of studies are increasing. NS has been used in alternative medicine in other parts of the world for ages. I was able to find NS in 400mg capsules at 60 capsules per bottle for less than $4 online from a popular supplier. To reach the most effective dose in the cholesterol study would require 5 capsules per day or about 35 cents or less per day if my math is correct.
