You don't want to take too little at a time though, because then there is a chance you might make some parasites immune to it. While you may be shedding some parasites, you might not be shedding others, and making them immune. I was reading the Humaworm website. They claim that if one person in a houhold has parasites it is likely that the others do as well, and they suggest that everyone living there do a parasite cleanse. I was looking at the Paragone formula. It has some interesting things in it, however I don't like the fact it has castor bean, and cascara sagrada(buckthorn) While some still like castor oil as an antiparasitic, some think it has toxicity and should be avoided. It is hard for me to find a formula with many ingrdients though,and not have objections to at least one ingredient in there. Of course I could take each herb separately, but to get a cleanse with many herbs this would be annoying to do.
