I started back in August. I cared for 3 I’ll family members one at a time but it was over a 3 1/2 week period of different severe cold and flu like symptoms. I suffer asthma when I get respiratory infections so I tried this to fight off getting sick. It worked for me. After being around the strep infection my tonsils were swollen like golf balls when I woke. I did the inhalation sprays. In 30 minutes my tonsils were normal! I was shocked! This happened at least 4 more times. I carry a bottle in my purse and keep one by my kitchen sink and 1 by my toothbrush. I have seen positive results. My family refused to try it. I like to do it before I brush my teeth. That way instead of rinsing my mouth right away I brush my teeth while the hydrogen peroxide coats my mouth. Then I rinse it out.
