Arteriosclerosis develops very slowly and takes years for arteries to develop zones of hardness and rigidness. The affected arteries turn out to be thickened and at the same time the arterials’ membrane loses elasticity. Arteriosclerosis may form in the coronary arteries, as well as in the vessels of kidneys, brain, and limbs. The deposition of an excess of calcium causes hardness of the arterial membranes.More:https://www.philahomeopathy.com/arteriosclerosis-atherosclerosis/
