Suggest Treatment For High Blood Pressure

I m just doing some research on calcified granuloma disease and calcified lymph nodes. These are stable and no change has occurred since last x-ray for my mom. Her Dr. has scheduled a ct scan in a few days just to make sure of X-ray result. She is 84 non-smoker. She s been pretty healthy and takes medication for high blood pressure. Needs to take vitamin d and multi vitamin. No other meds.
