Query: Great for blood pressure

This really helps with naturally controlling blood pressure. I have permanently added it to my supplements. My doctor said to me ...what ever I'm doing, keep it up. I would recommend giving this a try. It is inexpensive, and you got nothing to lose. No side effects for me (or any that I am aware of). Give it try for 30-60 days.
