Ear candling is generally classified as quackery and pseudoscience, as no scientific evidence supports it. Skeptics note that wax forms inside the hollow candle even when it is not placed inside the ear.
Placing a candle inside the ear may leads to burns, infection, obstruction of the ear canal and perforation of the eardrum.
At present, selling candles for ear-candling is illegal in Canada. It is also illegal to import such candles into Canada or the United States.
