Yes, Spring, I did. I initially used it to cure a toothache. It worked so well, I just kept doing it. This bigest difference I noticed was my skin, it became so soft. It really does make your teeth whiter and brighter, too. I also had more energy afterwards.
As for the consistancy, um, well, yeah, it's a little yucky. I was so paranoid about accidentally swallowing some oil, because they say the oil becomes full of toxins and can make you ill if you ingest it. Peppermint is supposed to counter-act that, killing the bacteria, so I just use a few drops of peppermint oil with the oil. The peppermint also makes the oil more tolerable.
I started with sunflower oil, but now I just use olive oil and it works just as well.
