Wow! Lots of views and misinformation on this thread. I'm a complimentary therapist and qualified in ear candling in 2006. It's not a sure fire cure for tinnitus. It's had no effect on mine at all, but I have had clients with tinnitus that have found it very beneficial so it is horses for courses.
It's only dangerous is you use unregulated candles and don't know what you're doing. It's not a difficult therapy to administer but there is obviously fire involved!
Biosun are the only candles I use. They meet EU safety standards which are pretty stringent!
The wax you find in the candle after treatment isn't from the ears, it's the beeswax from the candle. Some unrepeatable practioners will tell you it's the residue from your ears, but that's rubbish. The candle does produce a slight vacuum but it's not strong enough to such ear wax out of the ear canal. What it does do is equalise the pressure in the ears, which is why you have to do both. The warmth from the candle does soften ear wax and therefore makes it easier for your ears, which are self cleaning, to get rid of it. Also means it's more likely to come out in the shower and some people do find it deposited on their pillow! But the candles don't suck it out, that's a ridiculous claim really.
It is also a very relaxing treatment in it's own right. There's something very calming about the crackle and the smell is lovely too. I have clients who have ear candles specifically for relieving stress.
It's unlikely that much difference would be made to tinnitus after one treatment. I find a minimum of 4 treatments are needed to make a difference, but like I said, it doesn't help everyone, myself included. But I definitely wouldn't dismiss it if you've not yet given it a go.
