Hi Oma,
When I was looking for the nutritional value of bay, I ran across this information:
http://www.ehow.com/how_586896...
If you read it I'm sure you'll understand it better than if I try to explain it. I also found reference to bay regarding HBP on other sites but I think this one explains it better. I'm not knowledgeable enough about medicine to do much more than guide you to answers, so this is about all I really know.
Hope this helps.
