I would like to know what makes calcium deposit on a heart valve and if there is any nutritional way to dissolve it (put it back into solutio, thus clearing up the heart valve? ). This is a friend's current problem. The man is 62 years old and has been working in carpentry 6 days a week and working on his house the 7th day. The cardiologists have told him to stop working altogether, but he still works but doesn't do any more lifting.
