CANDLING has gained popularity in recent years. In this technique, a candle is placed in the ear canal. The wick is lighted and the candle is allowed to burn for a short period of time. Supposedly, the burning flame creates a vacuum at the other end of the candle, which can suck wax and other evil humors from the canal. When the candle is removed, the base of candle typically will appear dark brown, leading the person to believe that their ear wax has been removed by candling.
THIS IS A HAZARDOUS AND INEFFECTIVE TECHNIQUE! Hot wax can burn the external ear, and if any gets into the canal it can cause a painful burn, infection, or even a perforation of the ear drum. One could conceivably set one's hair or clothing on fire. REMEMBER: Just because it's ALTERNATIVE, it isn't necessarily GOOD!
