Thanks for the info all, did a little bit of research last night, and found out that American Indians used to use pumpkin seeds as a parasite killer. Found different ideas about how much you should take, one was about 16g a day for a week, and the other was a one of dose of 1oz (30g or about 120 seeds) followed by a dose of caster oil. I am on the Hulda Clark Maintainance program so am taking these to kill of any stuborn Tapeworm.
