I developed a sinus infection after battling pneumonia and the flu for a month. It started, of course, on a weekend. My face could barely be touched and my teeth ached so badly--- down to the jawbone. I was using hydrogen peroxide to rinse my mouth and throat and wondered if I could use it in a Neti pot. Thank you Earth Clinic for the confirmation of how to use it! I have used 3% hydrogen peroxide and distilled water, 1/2 and 1/2 in the Neti pot three times today. (10am-1pm-4pm.). Second and third time got better each time, face quit hurting, tmj joint pain almost gone and teeth feel like the fever they had in them is dissipating. Got a ways to go, it was bad! I'm on my way--thank you again!
