What is the best blood pressure medicine for extremely high pressure?

The best medicine for blood pressure is relaxation. As long as you are both mentally and physically relaxed you will not have high blood pressure. You can think of doing Yoga as "The art of Living " by Ravishankarji. Then lessen your intake of salt. Very important thing do not discontinue your medicines without the advice of your family Physician, because once you discontinue your medicines,your hyper tension might become more. So take care. I see that this is the first posting you are making. So let me welcome you to Mylot.
