Just regurgitation of conjecture and slanted bias being spouted by someone who has not seen in first-person the effectiveness of CS/IS or watch the wife stop a case of pneumonia(doctor diag + labs) without Antibiotics ! This silver has stoped the wife from having to use 5 to 7 doses of Antibiotics a year, and the problems that come their use. My 2yr old grandson stopped in 2 days a flu/cold that left the rest of his daycare class sick for over 10 days! Now everyone wants to use the ultrasonic nebulizer with CS when their kids get sick!(word got around how grandson got better just in 2 days)
