When I was little and I had an earache, my mom would take a cotton ball and dip it in warm olive oil that she had heated up to soothe the pain and make it feel better. It was also supposed to make the earache go away too. I know a lot of other kids had their parents do this too but I know my mom had gotten it from my grandma.
I’ve never had an earache so my mother never did this to me but after further research, I’ve learned that it is bad to put olive oil in anyones ear so I don’t know that this would be folklore I would pass on. I do know that this was a common way of soothing the pain.
