Ear candling involves the use of a hollow candle, which looks like a thick straw coated with wax. It is placed gently in the ear and the outer end is lit. The flame creates a gentle warm air vacuum in the auditory canal that draws out wax and accumulated debris from the ears. Because the eardrum is semi-permeable, fluid can also be evaporated during candling. This benefits sinus sufferers greatly. Ear candling is used to bring relief from wax build up, hearing problems, sinus problems, earaches, headaches, vertigo and tinnitus.
