Today I woke up with inflamed swollen tonsils. Having had tonsillitis at least twice a year for most of my life, I have tried A LOT of home remedies. The BEST and quickest acting one (that I used today) has been hydrogen peroxide!
I mix a dilution of 3% H202 (the one with NO additives! ) with distilled water. Usually about a tablespoon of each will suffice, then nebulize for 15 - 20 mins.
You can do this as many times a day as you need. I do it four times. I also increase my vitamin C intake (only natural vitamin C! NOT ascorbic acid! ) I make raw honey and lemon tea and gargle a 50/50 mix of ACV and water. I may attempt the coconut oil gargle also as I need to put in a full day at work and I have no voice!
