I was reading about internal cleansing products at www.drnatural.com . They also have a link down the page a ways to information about the most common internal parasites:
I have to say, the photos and descriptions there are enough to give one nightmares. It’s pretty horrifying to think of these things living inside of one’s body. I did have parasite lab tests done (on feces) on several occasions and they came out negative, but I’m still concerned. Having a giant tape worm living in one’s body could cause all kinds of symptoms and conditions. I wonder if it’s as widespread as they claim or if they’re just trying to scare the bejeebers out of us so that we’ll buy their products.
