I have parasites (for over 10 years), probably Tapeworm from undercooked beef. I eat about 1/3 cup canned pumpkin almost every day and it kills the tiny devils but not the large egg layer. This is the only thing that has given me relief. Gave 3 stool samples to Doctor at $100. each and they couldn't find them UGG. If I eat sugar/ sweet things and miss the pumpkin the parasites get very active around my rectum and virgina...it's horrible so I make sure and eat that pumpkin.
