a word of warning from my vcousin who is an ear nose and throat doctor:
he has seen ears damaged by wax dripping down and hurting the ear drum.
BUT i have heard of positive results, too.
the ear candles are long --one foot or so--conical hollow tubes which
are inserted in the ear, often with a paper plate with hole cut out
under them to catch ash and ear stuff. i have seen a plate with big
globs of stuff that came out of an ear..yuck! here are some sites..
