Well, you are on the right path to heal HBP condition you are in right now. It will take 15-20 days fast, plenty rest (very important) and drinking warm water will help. It took you many years to have this condition, normal function of many organs is needed in order to correct the cause. Also post fast lifestyle will need to change for HBP to normalize.
This is what Dr. Shelton has to say on the matter..............
"The speed with which fasting results in a marked reduction of blood pressure indicates the importance of rest in reducing systemic tension and excitement. The reduction may be so great in a very few days as to astonish the patient. As the toxic load is reduced, the nervous system becomes less irritated, the functions of the kidneys, adrenal, thyroid and pituitary glands are restored to normal, so that blood pressure falls to new levels, even to normal or slightly below, and tends to remain down after eating is resumed. Indeed, it will remain at or about the normal level so long as the patient continues to live in a manner to avoid the redevelopment of toxemia.
All of this is to say that the reduction of Blood Pressure secured by means of the fast is a GENUINE reduction and not a FORCED state. The organism is not crippled in the process as it is when a gland or portions of the sympathetic system are removed. If we cut out causes instead of cutting out organs, we secure a genuine and lasting elimination of effects.
As in all things, the causes that have produced the condition in the first place, will reproduce it if they are not permanently removed. Fasting is not a substitute for achieving------and holding to a correct way of life".
