I was wondering if you have tried using a neti pot? A friend suggested that I get one. So, I did last week and it has helped clear my head. I don't have sinus problems, but she had a friend who used one for sinus problems and it help a lot.
It uses salt water and if you know about salt it pulls moisture out.
2tuff recommends mixing some xylitol with colloidal ionic silver and using this as a nasal spray. It worked for me in clearing up a sinus infection. I also use a neti when I get sinus infections. I have thought about making homemade tooth paste with xylitol and baking soda but haven't done it yet. It has anti cavity properties too.
Hi. I think for mouthwash it is just fine to put some xylitol in water and swish. However, I had bad experience with making my own sinus stuff. I just used 1/4 tsp, xylitol in like 2/3 cup water, but it BURNED like crazy, so I tried the Xlear and it worked much better,
