I just ordered Dr. Anderson's Tapeworm specific herbal blend http://www.cleanse.net I haven't used it yet but will soon.
According to Dr.Clark the problem is not really getting rid of the tapeworm. It's the fact that their eggs/cysts are very hard to kill and remain in your body so getting rid of them is crucial to success.
On the Animal Planet parasites t.v. show the other day they showed a brain operation in china where they were removing a bag of hydatid (tapeworm) cysts. It was quite disgusting but nonetheless confirmed what Dr. Clark says about them travelling to other parts of the body and residing there.
