You need to start off with a bowel clease before you attempt doing a parasite cleanse, reason being that parasite will hide in a dirty bowel and the parasites herbs cannot get to the parasite because they hide inside the mucoid plaque. What does not kill the parasites makes them harder to kill.
I have only used psyllium and Bentonite for bowel cleansing. Click the link for information and instuctions on this.
Hopefully some one will come in and answer your question about other bowel cleansing products.
