If she stops the BP meds for a week, there's a risk of BP going up suddenly, causing heart attack or stroke. It's too risky. Besides, those tattoo paper, which you can apply on the skin with some water, and wash away with soap, are pretty good. There're so many to choose from, you can change one every week, cost like 0.1 dollar each time. I got a red rose on my arm, it lasts fro 3 days, before the rose I had an EKG image on my chest, pretty cool. There's an alternative, so why take the risk?
