Since there are different views Andreas says to cleanse the liver and colon first and as long you are clean you don't need parasite cleanse. They have no place to live.
Clark says to do parasite first but according to Andreas it would only work if your liver is clean otherwise it gets more clogged up.
So keep reading and do what you are comfortable with. I got liverflukes in 2 flushes and 2 years later did a parasite cleanse but did not see anything.
