I found a blog that gives links to more information about the insecticide in the CCWS and Candizolv: http://blogs.naturalnews.com/danger-chitin-synthesis-inhibitors/. There is even more scary information about it online, but this blog seems the most reliable collection of sources on the subject. Chitin Synthesis Inhibitors are the active ingredient in flea and tick medications. Chitins and Chitinase also used in treating wastewater and as a fertilizer for animal feed. They are not designed or approved for human consumption, much less is there an appropriate dose for humans. I don't know about you, but personally, I wouldn't ingest an insecticide, a fertilizer, or something used to treat wastewater, which is all these ingredients are approved for at the moment. Amazon and eBay refuse to allow anyone to sell CCWS or Candizolv through their websites, which alone should tell you something.
