Hi Karen, My mother occasionally experiences the same heartburn discomfort after taking ACV. She can't take it on an empty stomach and has to sip it slowly. She does take it every morning after breakfast diluted in 16 oz of filtered water. In regards to lowering blood pressure, she's had wonderful success with cayenne pepper. Do a search on Dr. Richard Schultz for lots more info. My Mom's doctor reduced her blood pressure med in half several months ago and my Mom hopes to be able to stop completely when she goes back in for her checkup in a couple of months. Besides eating well and taking the ACV and cayenne, she walks several miles 3 - 4 times a week.
