I don't know what this is but whenever I over do it with my candida diet, I get chunks of this stuff. One week ago I cut out all carbs (Fruits and brown rice) completely and I was taking oregano oil and undecenoic acid 3X a day. I got constipated and extremely ill (had such a bad sore throat I was spotting blood during coughing) and when I finally went to the bathroom I had lots of what you pictured.
Over the last week I've added olive leaf in and yesterday day I took 4X my normal dose before bed after having used a blood electrifier for an hour and today I had diahrea with the same stuff.
