I am not a medical professional so I am not handing out medical advice. This is MY earache remedy. It was good enough for my Gram and that makes it good enough for me. She used this on me my whole childhood and I keep a bottle on hand because I still get earaches.I warm a tiny bit of this by wrapping the bottle in a warmed towel or cloth. I soak the cloth in hot water and wrap it for a few minutes at most. Then I add a few drops to my ear, put a piece of cotton in it and cover with the warmed cloth. Then I lie down and keep that ear warm. Usually within a few hours I can tell it's getting better.I've tried all the traditional meds. They work but... They take forever to give me relief. I prefer this. It's cheap, I don't need to change into actual clothes, I don't have to go to the pharmacy, etc. Add in that it helps me faster and it's a grand slam folks. It's out of the park and in the next zip code. I don't need any further research. This is my remedy.
