I have heard of parasites coming out in urine. Personally, I've been seeing 1/2" inch
"threads" and things that look like little pieces of tissue paper. From what I've read, they could be either Candida or threadworms. I've tried Oxypowder
with Paragone and am now on Colonix. I also take Primal Defense. I read a testimonial on the Colonix website (www.drnatura.com) of a woman who saw visible worms in her urine after starting the cleanse.
I've never looked very closely after I've gone to the bathroom, until recently, but I've noticed things that look like liver flukes, lots of mucus and "tissue paper" material (probably Candida). Not to sound gross, but there may be some "things" hiding in your stools that you cannot easily see.
Hope this helps.
