I have a Tapeworm (for 10 years) which lays eggs and hatches tiny parasites. I eat pumpkin every day which helps keep the tiny wiggling parasites down. Along time ago I fasted for 3 days only drinking Sugar free metamucil with 1/4 c vinegar and started passing long stringy looking things like in your last picture. Doctors were no help. I eat 1/3 cup canned pumpkin right before bedtime. In the AM I drink a small glass of Sugar free metamucil with a splash of vinegar and I think that keeps my bowels clean most of the time. I especially eat pumpkin when I eat something with Sugar in it. The sugar make the parasites very active. The pumpkin kills them.
