Black stringy substance after liver flush

Today I did my 3rd Liver Flush and am a little confused as to what actually left my body. I performed the Andreas Moritz flush except I used lemon juice and olive oil. I released about 20 pea-sized green stones which was a little disapointing considering my last flush had about 200 or so, but I started to have a very dark diarehea. Close to black. Then for the rest of the day I was releasing this black stringy thread-like substance that came out in clumps of a half-inch or so. Not brown, black. Can someone tell me what this is. Is it parasites or bacteria or is it coming from the liver and gallbladder? Tweet
