ESSENTIAL OILS - peppermint reducing AD Burning

OK for years I was like no friggin way, this is hippie BS, but recently I was in Whole Foods and just put some peppermint essential oil on my burning cheek. Holy freak!! It started to neutralize it

So I had to test it further - I have been back in 4 times and each time it has helped. Dont think its for internal/oral use, but freak that I hurt, so I tried it and it did not eliminate it but did help reduce the burning on my tongue, gums, teeth, lips. No idea how bad this is to ingest these oils and I have not purchased it, but Ill tell you EVERY time I go in there I do it now

Anyone else try these oils??
