Hi Hilary: I believe that. My ex-husband had an enlarged heart. It would beat with so much fluid in heart sack that it created leasions. They finally just removed the heart sack. The one problem he had was getting sick. They (doctors) told him, no colds, no flu, no sore throats, etc. Now I couldn't figure out how you would accomplish that, but low and behold a script appeared. I can't off the top of my head remember the name, but he would take the med and poof, no cold, no flu, no sore throat, nothing. You tell me. Millions are made each year on cold/flu/sore throat remedies, someone is making BIG BUCKS to keep this junk on the market. Just my observation! TTFN G (don't mention my name)!
