This is true. My family has used H202 this way since I was a child. It was recommended by our family docter. It works like a charm, definately one of the first remedies I run to if my ears are popping and my tonsils are swelling. It is handy to have a fluffy handtowel that you can lay on then after the bubbeling subsides. It will itch and tickle like crazy. You can dump it out by placing your towel on the ear then tilting your head towards your shoulder. This is the best part. Then I clean the ear gently with a q tip or a soft cloth. Repeat the process on the other side. Also this is 3% regular H202 I am talking about, right off the shelf.
