A lit "candle" that can drip hot wax into your ear, usually as you lie on your side.
Sound dangerous? The Food and Drug Administration (FDA) thinks so, and is warning consumers to steer clear of products being sold as ear candles.
These "candles"—hollow cones that are about 10 inches long and made from a fabric tube soaked in beeswax, paraffin, or a mixture of the two—are being marketed as treatments for a variety of conditions. These conditions include ear wax buildup, sinus infections, hearing loss, headaches, colds, flu, and sore throats.
