I decided to try ozonated oils after reading about them on this site. I bought some ozonated hemp oil and watched my toes turn black. This was a good thing, as it killed the bacteria. I used a different toothbrush for each of the 4 toes affected, and used day and night. It took some time, and although I thought it was effective, I decided to add tamanu oil to the small container of ozonated oil. I mixed them together (half to half approx), and this has made all the difference. It's taken awhile, but they are finally clear. Well, the big toe that started it all, is almost done. There is still a tiny bit of black that needs to come to the top of the toe.
I am super excited that this worked, and wanted to share it. By the way, I'm using ozonated olive oil, but I don't think it really matters. I experimented with several and results were the same. And perhaps tamanu by itself might work. I didn't want to take the chance, since what I was using was working.
Good luck everyone, and I hope this helps someone.
