Hey - not to sway you in either direction - but here's the difference: The main focus of Colonix is colon cleansing with parasite removal being secondary. HUMAWORM's main focus is parasite removal with colon cleansing being secondary. With Colonix, you take three different products - with HUMAWORM you take one. Colonix is a fine product, ours is just different. Their website is http://www.drnatura.com and ours is posted over at the Ask Humaworm Forum here on CureZone.
