The precise medical definition of this is “increased blood pressure of unknown origin”. Just so that you know.
The origins have mostly to do with very poor quality blood (see the arthritis pages for more detail) and/or the chronic under function of the liver and kidneys. Whilst the large scale consumption of beef and/or pork and cow dairy produce will also cause high blood pressure, it will usually lead to arteriosclerosis as well.
The problem here is primarily emotional rather than physical so a slightly different procedure to that used for arthritis etc. is required to release it.
Logically, and experience also bears this out, the wearing of a Harmony Evolution upon the thymus gland for six weeks followed by one Harmony Evolution each front and back on the liver Photos men. Photos women. will cause this problem to gradually evaporate.
