How very odd that I came across this topic, sorry for digging up an old post...my brother buys and uses manuka honey on his cereal and stuff and a while back I had a bad sore throat and cold and started taking a couple of teaspoons of it a day on its own.
I began to notice spots of p on my chest fade out and nearly disappear and wondered "hmmm why has that faded out", now when my sore throat and cold went I stopped using the honey.
So I am now thinking maybe there was something to it, he was using really expensive (well £10 a bottle) organic manuka honey, my p literally in a few days had faded right out, I am stopping off to get some on my way home now!! Fingers crossed this works for me, how odd I never put two and two together before.
