How many people know that acyclovir does not always work nor prevents the transmission of Herpes?

Why is it that no one promotes the safer treatment of L lysine for Herpes instead of the dangerous pharmaceuticals?
Is it all about money or is this because people are unaware like doctors?
L lysine is safer and more effective along with promoting a good healthy diet high in antioxidants.

acyclovir
causes cancer and birth defects in unborn children L Lysine does not.

I use L-lysine when I get a mouth cold sore I began getting them when I began smoking. They go away really fast and since I quit smoking I do not get them as often except under stress.
Do any of you read the itty bitty information they write as warnings on these pharmaceuticals?
