When people are being told that Zimectrin Gold is "for the dog tapeworm"...take a look at what the dog Tapeworm cysts look like. There's a reason that Hulda Clark calls them the most dangerous parasite. That is what her "Clark cleanup" is for, the Hydatid cyst. It can get as large as an orange, and is full of scolexes. The brain and liver are the two most common places where they are found.
