I used RAW pumpkin seeds and they work to expel TONS of parasites. I ate them at night, maybe 20-30 seeds, the day of a colon irrigation. I had eaten little food that day, so the parasites ate all the pumpkin. I had eaten pumpkin seed before, but it was not raw. It must be raw. If this oil is pressed after toasting it might not be effective. Hope this helps.
