Also called "Ear Coning". It involves placing the narrow end of a specially designed hollow candle at the entry of the ear canal, while the opposite end is lit. Primarily used for wax build up and related hearing problems, ear candling is also used for ear infections and sinus infections.
Ear candling, also called ear coning or thermal-auricular therapy, is a folk medicine practice intended to assist the natural clearing of earwax (cerumen) and "toxins" from a person's ear by means of a hollow candle placed in the ear. It involves lighting one end of the hollow candle, and placing the other end in the ear canal. Some proponents maintain the resulting vacuum can clean out the ear, but mainstream medical science and manufacturers of ear candles discount this theory due to lack of evidence supporting it.
