Yeah, Hutzal, what medic8r cited. The residue inside the candles will be there ever burning whether or not the candle is placed in your ear. That part is complete bs. I also found an account where a person used an otoscope to look into a subject's ear before and after a candling session and saw no difference other than a slight mark where the end of the candle had touched.

Have you tried verifying the results in this way?
