I know it is a little late but I would like to put my 2 cents in here. What you need from the pumpkin seed is the oil. What this does is paralyzes the worm and detaches it from the intestinal lining so that you can pass it in your stool. I know this because it is what I have been using on my daughter to get her to pass her worms. It is non toxic and this method is used in Africa to deworm children. What you should do is ingest a good amount of the oil which you can purchase at GNC or any other health/vitamin store and take castor oil or a strong laxative with it. A sure fire way to get them to come out is to just do an enema an hour and a half to 2 hours after ingestion of the oil. With children you can purchase some suppositories that work immediately or just give them the oil a couple of hours before you know that they are going to go poo. This method is better for them. Anyway, the oil does not kill the worms it just paralyzes them. If you do have worms you should be able to find them in your poo after doing this. If you do put them in a ziplock and take them to your doctor for identification purposes!!
