The plaque which causes the blokage can be cleared by proper use of a naturally derived product called Cantron. A reputable website which sells Cantron is cancerchoices.com
I have personally witnessed the results of arterial scans before and after 6 months of treatment with Cantron. There was complete or partial clearing in almost all cases. The website will give you all instructions for its use- they have a consultation form. You must ask for this. Note that they are not allowed to say they can "treat" anything. The FDA has targeted them with hefty fines already for explained how Cantron functions. I can tell you. Cantron causes abnormal cells to die, and arterial plaque is an abnormal cell.
