The correct use of real, pure Sea Salt , and the right amount of water does NOT raise the blood pressure.
It's the use of bad salt, (denatured,iodized,bleached) and all that goes hand in hand with that -especially dehydration, and being starved for real food, ( which can manifest as holding onto a lot of acid accumulation in the form of fat and toxic sludge) that raises blood pressure.
Real salt and good water are a completely natural 'miracle'. They will reverse high blood pressure. Look into some of the archives here. Look at the book "Your body's many cries for water" ( the salt/water balance in the body is key) Or google Celtic salt, as an introduction to this area.
