@mobilian33 - Did you read the third paragraph. If you did then maybe you can understand why herbs can't replace prophylactic antibiotics. If you or someone in your family had bacteria growing in a heart value, are you going to tell me you would be happy taking garlic pills instead of one of these antibiotics?
Also, there are many people who have compromised immune systems and they depend on antibiotics to stay alive. Until we find something better we have little choice but to continue using antibiotics.
