This message is very old but I thought I'd add some information about Parastat (by Premier Research Labs).
I came into contact with Parastat because I visited a quantum reflex analyst who confirmed (with muscle testing) that I had a parasite, from the Caribbean, that was still in my intestinal track (and it was making my intestines weak causing a loss of energy).
I was shocked, because I had just finished a Barefoot herbalist parasite cleanse (that week) and had just finished a Humaworm cleanse 4 months before that. And I've done a total of 5 complete parasite cleanses at this point.
So my questions was: "Were the eggs just not killed or did the other cleanse just not kill this particular parasite?"
We did the muscle testing and of course the parastat helped. Unfortunately when we tested Humaworm and Barefoot, they did not kill this particular parasite.
The naturopath stated that Humaworm and Barefoot were quite good at killing North American parasites but the same ingredients weren't always effective killed other parasites (from the Caribbean apparently), but the problem is that this particular parasite is perhaps the most common parasite that he sees in his practice (in Canada).
I don't want anyone to get the wrong idea, Humaworm and Barefoot's dewormer have helped me immensely. BUT, they don't kill everything
Also, I learned that castor oil packs (used with heat and on a special cloth) should be used to force parasite eggs to hatch. Also, coffee enemas are great for flushing the dead parasites out. Also, the parasite cleanse is more effective if your body is alkaline, because if your body is alkaline, parasites have trouble living anywhere except for your gut (this was not a problem for me since I now have optimal PH on the Primal Diet). A lot of this information was new to me regarding parasite cleanses.
Anyway, I thought someone might benefit from my experience when they Google.
