I have often heard and read that high or low blood pressure is not a disease but a symptom of a basic physiological problem. Address the problem and the symptom will, in all likelihood, correct itself. In a search for the problem I would like to recommend a book that may, in many cases, lead to the source of the problem. The book is "Your Body's Many Cries For Water," by Dr. F. Batmanghelidg, M.D.
