There are 2 different views on this, since I was reading Andreas Moritz when I arrived here, I was never worried about parasites. At the first 2 flushes I saw liver flukes (like rolled up tomato skin) and never again. I did colon cleansing in between the flushes with Oxypowder . His view was that your colon and liver should be clean before you kill parasites so the dead ones can be eliminated.
As you know now there is the opposite view so you have to decide which way to go.
I did do a parasite cleanse after 2 years because I was curious, but I did not notice anything different.
