I'm probably the one you read in regard to lowering blood pressure. It did have a nice lowering effect initially. But like anything else having to do with BP it's hard to know. My BP has also been high lately and I've been forced to go back to my meds. They're unfortunately the only thing I can rely on to bring down the BP (though I'm at half the dosage and eliminated the other BP medications I was supposed to take with it).
I don't believe it's the OP though, since, after my first several months of OP I was able to almost completely wean off my meds (down to once or twice a week). I put it down to extra stress, and maybe Iodine
which I've just started, but not OPing since it had a clearly positive effect when I started. Of all my health issues/goals BP has been one of the hardest to get under control au naturale.
Also be aware that big pharma is at it again with BP. Based on no studies whatsoever, they've gotten physicians to lower what they consider normal BP from 90/130 to 80/120. Why? Obviously to bring millions of more people to the table to also pony up thousands a year for these dangerous drugs that cost pennies to make.
