Seminole -- ear candles are hollow conical tubes. The narrow tapered end is inserted in the ear and the other end is lit on fire. Yeah. Supposedly, the burning draws ear wax up into the candle. When finished, there is a substance that appears to be ear wax (and might be) or perhaps just residue from the burning candle. I can't say with any certainty based on the couple of experiences I've had.
Wasn't unpleasant, even somewhat soothing, but I can't claim much beyond that.
