Black Salve, whats going on?

I have a small (little smaller than a pencil eraser) basal cell skin cancer on my forehead. It was diagnosed and biopsied about three months ago. They recommended I come back to be tested to ensure they got it all.

Instead, I bought Bla-Cancema Black Salve distributed by McAdam Health in Montana. I've used it twice. The first time, I applied it and left it on for about 4 days, then reapplied it and left it on for two more days. I felt a little bit of tingling when I first put it on. Nothing apparent happened, I just assumed it must have worked. However, a few weeks later, it started to feel itchy and looked a little scaly like it did right before I had it diagnosed. So I applied it again after first opening it up with small punctures, and left it for 48 hours. It really burned this time, probably because I opened the skin. I washed it off and reapplied and again left it on for 48 hours. It got pus, then later a scap formed and fell off. Within a couple of days of the scab falling off, it again started feeling itchy and looking a bit scaly. I don't know what to do. Is this normal, part of the healing process? Is the cancer gone? Please help! Thank you. Tweet
