hanna
This might be a strange answer but I found this
parasite cleanse on the pet forum. I went to the site and it is for humans and can also be used by animals. And the price is right($6.95). I don't how good it is, but it might be worthwhile to try. A lot of the cleaners use the herb senna, this one too, it is suggested in general since you can become dependent on it to do it not more, some say 10 days, and some say 4 weeks. I know the colonix use senna tea with their cleanser too and a lot of cleanses do.
