Ear candling, also called ear coning or thermal-auricular therapy, is an alternative medicine practice used to improve general health and well-being. Ear candling can remove excess ear wax which helps alleviate many sinus related symptoms. Ear candles are hollow cones made out of fabric, covered in wax. The base is placed in the ear, and the other end is lit. The wax melts down the tube and enters the ear.
