If you want to add Bentonite Clay,that's perfectly fine.I would do colon - liver/gallbladder - parasite.Some parasite protocols would kill the beneficial bacteria as well.You could use probiotics or fermented foods such as yogurt or kefir.One non-toxic protocol is 10g MSM a day for 10 days.This greatly lessens the ability of the "glue" they use to latch on.Another good thing is Olive Leaf Extract.It has amazing anti-parasite-anti viral-anti bacterial properties.With this, many sub-clinical,chronic conditions may be relieved.I use both of these all the time as part of my regular supplementation.They are both available in cheap,bulk powder form at
