Hypertension, An Alternative Approach

For many years high blood pressure has been defined based upon actuarial
tables prepared by life insurance companies. By that definition, blood pressure
of 140/90 is borderline hypertension in a person 40 years of age. The
suppressed fact is that blood pressure should rise by 5 points for every decade
of life. Therefore, 145/95 is borderline hypertension in a person of 50 years
old; 150/100, in a person 60 years of age, etc. However, that standard is
almost never applied in prescribing high blood pressure medications.

Recently, a new standard is being applied: 120/80 (for years the gold standard
in blood pressure) has been redefined as "pre-hypertension," with the
recommendation that medication be prescribed. And, there is no allowance for
increasing age. So, we see headlines such as "Hypertension - An Emerging
Epidemic" on WebMD.

Another very important fact is that most primary hypertension is diagnosed as
"idiopathic," which basically means the doctors do not know what's causing it.
We've had a variety of medical recommendations for years, but the overall
impact has been minimal (as evidenced by the statistic in paragraph 1, above).
These recommendations include: 1) drug therapy, 2) exercise, 3) dietary
restrictions on salt and fat, 4) weight loss, and 5)avoidance of drugs, including
tobacco and caffeine. The medical point of view is that lifestyle changes are
inadequate.2

I would like to share with you the basic mechanism of "essential" or "idiopathic"
hypertension. These terms are applied to primary hypertension unrelated to an
underlying disease of the kidney or diabetes. Essential hypertension is the
body's physiologic response to insuring an adequate blood supply to the brain.

For a moment, we need to digress so that you have a picture of how the
circulatory system for the brain works. Inside the cranial vault, the blood
reaches the brain through the carotid and vertebral arteries. It is drained out
into the jugular vein through a system of sinuses which are actually formed by
the meningeal membranes. The meningeal membranes (or dura) are the
fibrous structures which separate the lobes of the brain and actually give the
brain its shape. They include the falx cerebri (which divides the two cerebral
hemispheres), the tentorium cerebelli (which separates the cerebellum from the
occipital lobe of the cerebral hemispheres), the falx cerebelli (which divides the
cerebellar hemispheres) and the diaphragma sellae (which covers the
depression in the skull in which the pituitary resides).3 {You may visit my
website RichardsFamilyHealth.com and view the articles on "Cranial" to view a
cross section of these structures.}

Being membranous, the dura is affected by distortions in the cranial vault,
resulting in twisting of the sinuses and restriction of the outflow of blood from
the brain. Therefore, to bring in more fresh blood and oxygen, higher
peripheral pressure is required to force through the blockage. While in school,
I was privileged to see a dissection of an unpreserved cadaver, demonstrating
the lines of stress in the dura due to cranial distortions. Strokes may occur
when the cranium shifts, suddenly allowing a surge of high pressure through
the fragile capillaries in the brain.

Interesting confirmation of this mechanism comes from veterinary medicine. A
giraffe has a peripheral blood pressure of about 350/300 in order to get blood
to the brain. Yet, their intracranial pressure is very similar to humans. They
also have a specialized vascular structure at the base of their brain to
compensate for changes in pressure as they raise and lower their heads while
feeding and drinking. The critical point is that the higher pressure is necessary
to pump the blood up into the brain.

So, the question becomes: What can be done about essential hypertension?
Probably the most effective way to control it is through cranial adjusting,
restoring normal motion to the cranial vault and removing the restrictions
which cause the pressure to rise. I have spoken to many alternative health
practitioners, and the consensus of opinion is that the effect of herbal
interventions is minimal, compared to the benefits of cranial adjusting. As an
added benefit, cranial therapy is completely free of side effects! {See my article
on the side effects of high blood pressure medications at

Of course, if there is underlying pathology, either diabetes or renal disease,
that process needs to be addressed as well. In many instances, that means
herbal therapy or nutritional supplements.
