I'm sorry, but... WTF?
Here's a quote from the web site:
It was long believed that ear candling actually "drew out" earwax through suction, or a vacuuming effect. However, we now know that very little if any of the residue left in the unburned portion of the candle is actually ear wax. Most of it is created by the burning of the candle itself. It is just not possible for an ear candle to be powerful enough to suck out ear wax. Candling can however, soften and loosen impacted wax allowing the wax to find its way out of the ear canal naturally.
You know what else softens ear wax and allows it to "find its way out"? Hot showers.
Given the aroma I've experienced rolling off some of the "dirty hemp people" I've met, perhaps they should try a little soap and hot water first. It's much cheaper, and doesn't leave you smelling like a wet llama in a smokehouse... with a burning candle sticking out of your ear, let's not forget.
