6 year old thread bump. Actually found it through Google..clicked and was still logged in here so I'm posting.
I've been blending/grinding them and drinking them in a smoothie/shake and getting weird stomach cramps from it. I end up in the bathroom afterwards but even after the cramping is still there. Not painful but just something. I was also wondering if it's killing parasites or pissing them off. I don't think it's the particular seeds.. I've used a few different brands.
I've eaten the WFN brand in the past. Definitely quality products but just too expensive to use regularly
