I'm 69 And Do Not Take Any Drugs. However, My Blood Pressure Has Been Rising Since I Switched To ADA Approved Listerine Zero. It Has Been Running 150s over 86. My Doctor Expressed Concern A Couple Of Weeks Ago. I Went Home And Started A Search About Things That Could Cause Blood Pressure To Be Eleveated. (I've Always Been Athletic, Lift Even Today 25 lbs. Barbells, And Ride My Bike 20 Plus Miles A Day Several Days A Week. I Stopped Using Both Listerine Zero, and ACT Mousewashes. My Blood Pressure Within A Week Returned Back To 126 Over/80.
