I had scary bright red bits coming out of me for a while also. I was really worried about it, and did some researching and found all my answers here at curezone. Like dandilion said, you are probably just eliminating parasites due to the oregano oil.
I found out that parasites love to suck up the vitamin b-12 from your body, which is a bright rosy red color and it turns them bright red.
Refer to this thred from when I was figuring it out. I hope it helps you to feel better.
