That was a good suggestion. It is worse to let them just die inside you and get stuck in bowels and liver.
So besides colosan you can start liverflushing, check on that forum and under cleanses at top of page.
Liverflushing gets the liverflukes out. Just doing parasite cleanse is not enough.
The colosan cleans all the intestines, like the small intestines, and the colonic only the large bowel.
