Calcarea Flourica -- Hypertension

Dear All
I have read the posts by Dr.Sajjad Akram on Hypertension because i also suffer from the same.

He has prescribed Arnica and Calc flour for hypertension in one of his posts.

But in Materia Medica of Boericke , the dosage for calc flour is given as follows:-
' Dose.--Third to twelfth trituration. A 'chronic' remedy. Needs some time before manifesting its effects. SHOULD NOT BE REPEATED FREQUENTLY.'

After reading this i had some confusion. Can somebody throw some light on the restriction that why this medicine should not be repeated frequently.

As given in Dr.Schussler's
12 Tissue remedies,(Boericke),Calc Flour is described as a medicine to be given when the blood vessels has already lost the elasticity and is to be prescibed to tighten up the blood vessels.
But this medicine is prescribed when the patient is already having Blood pressure due to tightening of the arteries. Would'nt the medicine prove to be counterproductive , if we go by the characterestics of the medicine described in the standard texts?
let me quote the relevant paragragh from the book,

'... In the human body, Calcarea Fluorica, Calc. fluor., or Calcium Fluoride, is found in the surface of the bones and in the enamel of the teeth. It is also a constituent of the elastic fibers of epidermal tissues such as:
Skin
Connect Tissue
Vessel Walls
A disturbance in the balance of Calc. fluor. or Calcium Fluoride in any of the body tissues, can cause a chronically relaxed condition of any of the associated tissues. If the elastic fibers of any portion of the vessels of the connective tissues or lymphatic system have arrived at such a state of relaxation, it is thought that the osmotic transfer of body fluid can be interrupted and that fluids will accumulate in these cellular tissues. It is also known that when the elastic fibers of the blood vessels are disturbed by an imbalance of the molecules of Calc. fluor. or Calcium Fluoride, enlargements of blood vessels can take place such as:
Piles, hemorrhoids
Varicose or Enlarged Veins
Hardened Glands
Organ Displacements
Weakened Abdominal Walls
Hemorrhages of Organs or Tissues.....'

Any body in this forum who can clear my doubts, will be most welcome to reply to this post.

with regards,
