Dear Art.
Calcium buildup in your arteries is secondary to plaques or
blockagesPeripheral artery disease in them. It is unlikely that your herbal preparations would help this.
I would suggest a full medical evaluation by a physician to determine the significance if any of these blockage. Blockages in your carotid arteries can cause stroke and blockages or changes in the abdominal aorta can cause significant problems if left unattended to.
