Thanks for the tip about using oregano oil for tooth aches. I always used oil of cloves, which also works well. The oil of cloves will burn mucus membrances and skin, so when I use it for tooth aches, I stick a tooth pick in the the bottle and apply it with the tooth pick.
When I eat the oregano oil, I just put it straight from the dropper into my mouth, half a dropper full or more, and then chase it with a glass of water. *S*
