Whenever I got tonsillitis (and I did get that quite a lot), I normally would just gargle with hot water and salt. I’m afraid of doctors so that seemed to be the best solution for me. The tonsillitis would normally go away after a few painful days anyway.
When I got married, my mother in law introduced me to Kamillosan M Spray. At that time, she wanted me to use it on a big mouth sore that I had. So I did. Amazingly, the mouth sore went away the very next day - Which was perfect timing because we had a big benefit dinner at work, and with the mouth sore gone, I could eat all the foie gras that I wanted. Haha!
I made sure to keep a small bottle of Kamillosan handy since then. And when I got another bout of tonsillitis, I tried spraying Kamillosan right on there. Well, as far as I can get anyway. It tasted weird. It is a bit unpleasant, but tolerable. And I kept at it until my tonsillitis went away. On average, I noticed it would cure me of my tonsillitis within 2-3 days on average. Back then, I’d get it for about a week or so. So 2-3 days is wonderful!
