If you were me, I would do the parasite cleanse first! Get them out of there as fast as you can! Then when you are finished move on to the colon cleanse, and the Liver Flush you can do whenever, is my belief.
However, I would not do that while you are on the cleanse because you are going to feel horrible already....Also, I personally would not combine the parasite cleanse and colon cleans at the same time, as you don't want to bind any of the herbs to the fiber and loose its impact, BUT you can combine them...I just wouldn't...
Lastly, humaworm has such sweet staff! If you have any questions they are always happy to help there!
