I haven't had geographic tongue myself.. but I had found a review on manuka honey getting rid of it.
I suggested it to a girl with geographic tongue and she ended up using 80+ mgo manuka honey, a spoon a day.. which got rid of it.
However, she started forgetting to have the honey and it came back. So if anyone tries and sees results, you may need to keep having the honey for a while before tapering off..
On another note, some believe geographic tongue could be caused by being around mould.
Whether it's a water damaged building or mould coming out of air conditioning units.. some might be living with it or working in it..
There's a study showing normal honey *quote* can inhibit the harmful and genotoxic effects of mycotoxins and improve the gut microflora.
So normal honey may help as well.
