We all carry parasites and those of us who have a dysfunctional digestive system and low immunity tend to carry more than healthy people in areas with good sanitation. Up to the early 1900's people would often do a spring parasite cleanse with sulfur or Wormwood . Flukes in the stool look similar to small pieces of tomato skin, the ova are too small to see. They are related to leeches, liver and intestinal flukes have a similar shape. It is rare to see adult flukes in the stool, most are quite small. Age spots and liver spots are referred to as fluke spots, brown, raised pigmented areas on the skin. Small Tapeworms are very common as are roundworms such as Ascaris.
