Narrowed, hardened arteries seem to be part of the cardiovascular picture, and is one of the causes of hbp. I did cheleton therapy before to clean up my arteries, but it did not seem to work for my bp. Then I went on to do "master cleansing"
for a week. I don't know how much it cleared up the plague in my arteries neither, but I know it was very good for my bp.
Regarding Mukta Vati, I went back to http://www.herbs2healyou.com
to read the ingredients of this formular, and it said that many of the herbs in this formula actually deal with cardiovascular system. So perhaps you can check it out in their page
I guess herbs work differently than drugs. You gotta give it some time to slowly show its power. But you get so side effects at all. So our choice is not that hard to make.
