I am the one who used the term "slicing and dicing." That was a little over the top I guess.
Some people actually do have a bad reaction to the silica in DE, but apparently not due to its sharpness.
GI tissues are far tougher than itty bitty worms. Aside from that, though, there are so many aninals that are given it for parasite cleansing, with no negative reports that I know of so far.
For sure we know parasites are doing awful things to our bodies. If you can get rid of them without DE, great. But if not, all I can say is I have used it off and on for over a year and a half as part of a maintainence program and I have seen no decline in my health, only increase in health. Plus, my nails are now tough as...nails.
