how about this :
This rang a bell for me. I remember about 4/5 years ago, went to stay with a friend for a week. And every morning, he sprinkled nigella seeds on my porridge in the morning. By the time I went home, I did feel a lot better. He gave me a jar to take home, but I lost it, and thought no more about it. Think I'll be buying myself some more of these...
