Sgt -- here's an excellent article explaining high blood pressure, it's effects, the various types, etc., and, going further down on the pages you will come across several modalities of treating it, including everything from prescription medications to natural alternatives, ways & means, etc.

If you opt not to take a blood pressure medication and wish to try alternative options, it would be best to find a reputatble naturopath who can help you in that sphere. Or even an integrative M.D., if possible.
