Yes parasites look like your pictures here when they are whole and have not suffered from decomposition. But, with herbal treatments they usually do not come out whole and undecomposed. With Praziquantel or some of the other medicines sometimes they will come out quickly enough to be identified before they decompose, but mostly they won't. I myself had this happen after taking praziquantel and doing a flush within a day of taking the prazi. A whole fluke undecomposed came out looking exacly like it was suppose to look. Even with Prazi though they will still come out like tomato skins and partially decomposed as well. Unless you have a surgery or an instrument to pull a live one out this will always be the problem. Anyone who says that the parasites don't decompose inside of you after they are killed is being very misleading.
