In reply to Paddy_nolan:
Have you seen a doctor about it?
I ask because my wife had tonsillitis a week or so ago.
Went to the doctor who said it looked like Strep A (something about red bands in the mouth or something).
Doc basically said it unlikely to clear up on it's own and Strep A kills a lot of people in the UK by it not being treated.
He also said that there's no antibiotic resistance in Strep A so antibiotics are very effective at treating it.
So I wouldn't self medicate for tonsillitis.
If it's viral, I can't imagine there's much in terms of home remedies that will make any difference. Except for eating lots of ice cream and hot toddies containing lots of yummy whiskey. You deserve it.
If it's bacterial (not sure how you would know) then saltwater and diluted tcp gargling sounds like as good as anything.
