It's amazing too inside her mouth - I know she's probably raw and it burns like a B^tch but I would put a teaspoon in my mouth let it melt swish for 1.5 minutes and swallow. It held off most of the bad side effects until the last three days of treatment when I finally broke down and had a pain med (I would get mouth sores and blisters but they wouldn't pop, so it was less painful.) I swear I used it from week three on. I stopped swishing probably the last week of treatment because it became crazy painful - then a week after treatment finished I thought I had a bit of thrush so I told my rads guy. He said the magic mouthwash will help it has nystatin in it... I had been using only that so I knew it wasn't helping so I started back on the manuka and in two days it was gone. after you swallow it numbs you. It's antibiotic, antibacterial, anti inflammatory. Love it. Plus it doesn't cause cavities becaus it is anti bacterial.
