“A review of the literature identified one systematic review of the available evidence on ear candling. Seely et al (1996) found that ear candling does not produce any negative pressure (the purported mechanism of action) and does not remove cerumen (ear wax) from the ear canal. They found no existing evidence to evaluate regarding claims that ear candling treats other medical conditions such as sinus infections. Safety concerns associated with ear candling include danger of burns, of depositing melted wax into the ear canal, and perforated eardrum. During the past few years, the FDA has banned the importation of auricular candles marketed by at least four Canadian companies.” Clinical practice guideline from American Speciality Health Inc.
