I'm surprised that you have no mention of horseradish on your website. I used to take antibiotics at least once a year for sinus infections until 12 years ago when my naturopathic doctor recommended horseradish. Since then, I have had no problems if I eat a lot of horeradish (usually about a jar a day) at the first sign of infection. Until now, that is. I have developed a sinus infection and the horseradish I just brought home from the grocery store is not strong enough. So, I am going to try some of the other things listed here, at least until I can get my hands on some stronger horseradish.
