Sinus infections! I dread that word. I used to suffer from it when I was young. Have had numerous doctor consultations and much expenses plus sufferings, plus much medicines. When I was a student in Belgium 30+ years ago, an ENT (Ear, nose and throat) specialist in a University hospital even wanted to pour liquid nitrogen into my nose. I don't know if he had wanted to use me as a guinea pig.
What are the sinus infection symptoms? That site give a list of symptoms which if you have, you will have to take action. A normal person's reaction is to consult an ENT (Ear Nose Throat) specialist. I have been through that and I know what is involved. I wished that the Internet exist then and I had found this site: how to cure a sinus infection because they offer a natural cure for sinus infections. They use ionic colloidal silver solution, a 100% natural mineral supplement. Just look at their long list of testimonials.
According to Dr. Henry Crooks, silver is highly germicidal, quite harmless to humans and absolutely nontoxic. His conclusions from his bacteriological experiments with silver is that there are no microbe that is not killed in laboratory experiments within six minutes. If I had came to know about the above site, I might just give them a try.
